  • [Title] A peculiar complication of suprapubic catheterization: recurrent ureteral obstruction and hydronephrosis.
  • Some serious complications include bowel perforation and obstruction.
  • Computed tomography (CT) of the abdomen revealed severe right hydronephrosis and hydroureter due to obstruction of the right distal ureter by the SPC tip.
  • CT of the abdomen again revealed severe right hydronephrosis and hydroureter due to obstruction of the right distal ureter by the SPC tip.
  • Follow-up CT of the abdomen 2 months later showed complete resolution of the hydronephrosis and hydroureter.
  • CONCLUSION: This case illustrates that obstruction of the ureter by the tip of an SPC can be a cause of recurrent hydronephrosis and urosepsis.

  • [Title] Etio-pathogenic and morphological correlations in congenital hydronephrosis.
  • Hydronephrosis, "distension in varying degrees of pelvis and calyces, accompanied by progressive atrophy of renal parenchyma due to obstruction in urinary flow", is an apparently simple reno-urinary disease, but, in reality, by association of its own characters with those conferred by causative lesions, becomes of a significant complexity.
  • The purpose of this paper is to demonstrate the plurivalent character of this entity on a batch of cases with congenital hydronephrosis, by identification of lesional features correlated with cause of disease.
  • The etiology of hydronephrosis in analyzed cases was characterized by heterogeneity: polar inferior artery, horseshoe kidney, extrarenal pelvis, transverse valves of pelviureteral junction (PUJ), adhesion of ureter to PUJ, intrinsic stenosis of PUJ, vesico-ureteral reflux, posterior urethral valves, stenosis of urethral meatus.
  • The way of intervention of urinary obstruction and the uni- or bilateral character of damage were definitory for the macroscopical appearance of the hydronephrotic kidney, renal pelvis demonstrating its role of expansion room for kidney protection.
  • In analyzed cases of congenital hydronephrosis, correlation specific cause-pelvic lesion evidenced histopathological differences related to etiology.
  • Regardless of etiology, all cases of congenital hydronephrosis were characterized by varying degrees of fibrosis in chorion of renal pelvis, accompanied by active chronic inflammation, observation that support the idea of connection between the two pathological changes.

  • [Title] Retrocaval ureter: the importance of intravenous urography.
  • Retrocaval ureter is a rare cause of hydronephrosis.
  • Differentiation from other causes of urinary tract obstruction, especially the more common urolithiasis, is important for successful surgical management.
  • Current practice has seen multislice computed tomography (MSCT) rapidly replaces intravenous urography (IVU) in the assessment of patients with hydronephrosis due to suspected urolithiasis, especially ureterolithiasis.
  • However, MSCT, without adequate opacification of the entire ureter, may allow the physician to overlook a retrocaval ureter as the cause of hydronephrosis.
  • High-resolution IVU images can demonstrate the typical appearance that leads to the accurate diagnosis of a retrocaval ureter.

  • [Title] 'Tissues' associated with 'No Hydronephrosis': Top Publications.
  • [Transliterated title]
  • Background: There are articles published each month which present 'Tissue' for 'no hydronephrosis'.
  • Finding such articles is important for researchers, clinicians, and patients.
  • However these articles are spread across thousands of journals, and there are many types of 'Tissue'.
  • This makes searching and locating the relevant publications a challenge.
  • We have used BioMedLib's semantic search technology to address the issue, and gathered all the pertinent publications in this review article.
  • Methods: We categorized the publications we found into two groups.
  • We used the strength of textual-association to separate the groups.
  • In group one there are publications with the strongest evidence of association. We focused finding the most relevant publications pertinent to our goal, rather than combining them into a conclusion section. Such textual synthesis will be the focus of our next project.
  • Results: Group one includes 15 publications, and group two 6663 publications.
  • Here are the top 9.

  • [Title] Antenatal hydronephrosis.
  • The diagnosis, workup, and management of prenatal hydronephrosis have undergone a swing from preemptive surgical treatment to a more conservative approach as the natural history of the differential diagnoses becomes more appreciated.
  • We examine different radiologic tests for determining the diagnoses associated with antenatal hydronephrosis.
  • A review of the more common differential diagnoses of prenatal hydronephrosis and current treatment options for ureteropelvic junction obstruction, vesicoureteral reflux, ureteroceles, ectopic ureters, and megaureters is undertaken.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Pure transperitoneal laparoscopic correction of retrocaval ureter.
  • BACKGROUND: Retrocaval ureter is a rare congenital abnormality.
  • Operative repair is always suggested in cases of significant functional obstruction.
  • Laparoscopic procedures have been employed as the minimally invasive therapeutic option for retrocaval ureter.
  • However, the laparoscopic techniques for retrocaval ureter might be technically challenging to some surgeons.
  • The aim of this article was to present our experience and surgical techniques of pure transperitoneal laparoscopic pyelopyelostomy and ureteroureterostomy in nine patients with retrocaval ureter.
  • METHODS: A total of nine patients of retrocaval ureter underwent pure laparoscopic pyelopyelostomy or ureteroureterostomy.
  • The distal part of the dilated renal pelvis was transected at the ureteropelvic junction and the ureter was relocated anterior to the inferior vena cava.
  • The symptoms disappeared and hydronephrosis decreased substantially after surgery.
  • CONCLUSIONS: Pure transperitoneal laparoscopic correction for retrocaval ureter was associated with an excellent outcome, minimal invasiveness and short hospital stay.
  • It is technically feasible and reliable for retrocaval ureter treatment.
  • Laparoscopic surgery could be the standard treatment for retrocaval ureter.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ureter myogenesis: putting Teashirt into context.
  • After the basic shape of the mammalian ureter is established, its epithelia mature and a coat of smooth muscle cells differentiate around nascent urothelia.
  • The ureter actively propels tubular fluid from the renal pelvis to the bladder, and this peristalsis, which starts in the fetal period, requires coordinated smooth muscle contraction.
  • Teashirt-3 (Tshz3) is expressed in smooth muscle cell precursors that form the wall of the forming mammalian ureter.
  • Null mutation of Tshz3 in mice leads to failure of functional muscularization in the top of the ureter and this is followed by congenital hydronephrosis.
  • The phenotype of Tshz3 mutant mice resembles that of human congenital pelviureteric junction obstruction, and we suggest these individuals may have mutations of genes encoding molecules in the differentiation pathway mediated by Tshz3.

  • [Title] Hydronephrosis following ureteral reimplantation: when is it concerning?
  • OBJECTIVES: Hydronephrosis without obstruction is common prior to ureteral reimplant, especially in patients with high-grade VUR.
  • Consequently, when hydronephrosis is present post-operatively, it is unclear when it should be concerning.
  • We evaluated the finding of hydronephrosis in children undergoing reimplantation and its evolution following surgery.
  • RESULTS: Hydronephrosis was observed in 24% pre-operatively and 21% post-operatively.
  • 52% with pre-operative hydronephrosis had it post-operatively, while 12% without pre-operative hydronephrosis had it post-operatively.
  • 71% of post-operative hydronephrosis resolved on average in 1.36 years.
  • 19% didn't resolve and 0.1% had ureteral obstruction.
  • Risk factors for post-operative hydronephrosis included increasing severity of VUR, and high degree of pre-operative hydronephrosis.
  • CONCLUSION: Hydronephrosis following ureteral reimplantation is not rare, and correlated to pre-operative evaluations.
  • Post-operative hydronephrosis is frequently transient and benign, and usually resolves within the first 2 years.
  • Patients with high-grade VUR and hydronephrosis pre-operatively, however, are at risk for developing worsened hydronephrosis and should be followed with a 3-month post-operative ultrasound.

  • [Title] Results of a practical protocol for management of prenatally detected hydronephrosis due to ureteropelvic junction obstruction.
  • INTRODUCTION: Several algorithms exist for the management of prenatally diagnosed hydronephrosis due to ureteropelvic junction obstruction (UPJO).
  • RFS was reserved for those with worsening hydronephrosis or that which failed to improve on US by 1 year.
  • Gender, side of UPJO, degree of hydronephrosis, mode of management, and current status of the patients were noted.
  • Obstruction was bilateral in 55 (39%) patients.
  • Initial US grade of hydronephrosis was Grade 1 in 56 RU (28%), Grade 2 in 51 RU (26%), Grade 3 in 50 RU (25%) and Grade 4 in 41 RU (21%).
  • Spontaneous resolution of hydronephrosis was observed in 87 RU (49%), while 10 RU (5.6%) eventually required surgery for worsening appearance or function on US or RFS, respectively (n=8), symptom development (n=3), and/or parental preference due to persistently prolonged T1/2 (n=4).
  • Seventy-two RU (40.4%) remain under surveillance with improvement (47.2%) or stable hydronephrosis (47.2%) in 94.4%.
  • Spontaneous resolution of hydronephrosis and/or favorable prognosis was encountered in 87% of conservatively managed RU.

  • [Title] Impaired EphA4 signaling leads to congenital hydronephrosis, renal injury, and hypertension.
  • Experimental hydronephrosis induced by partial ureteral obstruction at 3 wk of age causes hypertension and renal impairment in adult rats and mice.
  • Genetically modified mice, where the cytoplasmic domain of the EphA4 receptor has been substituted by enhanced green fluorescent protein (EphA4gf/gf), develop spontaneous hydronephrosis and provide a model for further studies of the disorder.
  • The present study aimed to determine if animals with congenital hydronephrosis develop hypertension and renal injuries, similar to that of experimental hydronephrosis.
  • EphA4gf/gf mice developed variable degrees of hydronephrosis that correlated with their blood pressure level.
  • In conclusion, congenital hydronephrosis causes hypertension and renal damage, similar to that observed in experimentally induced hydronephrosis.
  • This study further reinforces the supposed causal link between hydronephrosis and later development of hypertension in humans.

  • [Title] Molecular pathology of murine ureteritis causing obstructive uropathy with hydronephrosis.
  • Primary causes of urinary tract obstruction that induces urine retention and results in hydronephrosis include uroliths, inflammation, and tumors.
  • In this study, we analyzed the molecular pathology of ureteritis causing hydronephrosis in laboratory rodents.F2 progenies of C57BL/6 and DBA/2 mice were studied histopathologically and by comprehensive gene expression analysis of their ureters.
  • Incidence of hydronephrosis was approximately 5% in F2 progenies.
  • Histopathologically, this hydronephrosis was caused by stenosis of the proximal ureter, which showed fibrosis and papillary malformations of the proliferative epithelium with infiltrations of B-cell-dominated lymphocytes.
  • Eosinophilic crystals were characteristically observed in the lumen of the ureter and the cytoplasm of large granular leukocytes, eosinophils, and transitional epithelial cells.
  • The Ym1 protein was mainly localized to the cytoplasm of the transitional epithelium, infiltrated cells, and eosinophilic crystals in diseased ureters.We determined that the primary cause of hydronephrosis in F2 mice was ureteritis mediated by the local hyperimmune response with malformation of the transitional epithelium.

  • [Title] Evaluation of hydronephrosis with tubeless cutaneous ureterostomy using Tc-99m MAG3 diuretic renography.
  • PURPOSE: To assess hydronephrosis of tubeless cutaneous ureterostomy using Tc-99m mercaptoacetyltriglycine (MAG3) diuretic renogram.
  • Stomal obstruction was evaluated with Tc-99m MAG3 diuretic renography 3 months after the surgery.
  • RESULTS: T1/2 means were 7.27 +/- 7.11, 5.69 +/- 4.63, and 8.96 +/- 8.37 minutes for total, ipsilateral, and contralateral kidneys, respectively, in side relationships between ureter and stoma.
  • Six months after the surgery, of 26 renal units (96.3%) that had achieved a tubeless condition, and 25 renal units (92.6%) had no hydronephrosis.
  • Mild hydronephrosis without the need for intervention was present in 1 renal unit (T1/2, 31.70 minutes).
  • Catheterization was performed in one renal unit (T1/2, 21.04 minutes) due to acute pyelonephritis and persistence of grade 2 hydronephrosis 5 months after the surgery.

  • [Title] Bilateral congenital midureteric strictures associated with multicystic dysplastic kidney and hydronephrosis: evaluation with MR urography.
  • The severity of obstruction differed in the two ureters, resulting in a multicystic dysplastic kidney (MCDK) with an atretic ureter on one side and hydronephrosis that worsened over time due to progressive stenosis on the other.
  • Although midureteric strictures are usually misdiagnosed as ureteropelvic junction (UPJ) or ureterovesical junction (UVJ) obstruction on conventional imaging, MR urography was able to clearly demonstrate both the anatomical and functional abnormalities.

  • [Title] Hydronephrosis after radical hysterectomy: a prospective study.
  • One part of the operative procedure of radical hysterectomy (RH) is the dissection of the ureter from its overlying tissue and this may result in injury to the ureteric adventitia.
  • This might induce ureteric obstruction and consequently produce hydronephrosis.
  • The objective of this prospective study was to evaluate the incidence of hydronephrosis after RH in patients with early stage cervical cancer.
  • Patients who had hydronephrosis before surgery, suffered intraoperative ureteric injury, or were lost follow-up at 7 days after surgery were excluded from the study.
  • Right hydronephrosis was detected in 16, 7, 5 and 3 patients, and left hydronephrosis in 16, 11, 3 and 1 , at 7 days, 6 weeks, 3 months and 6 months, respectively, after the operation.
  • Hydronephrosis persisted in 8 patients (15%) after 3 months.
  • One patient who developed hydronephrosis had local recurrence and received further treatment with concurrent chemoradiation therapy.
  • In conclusion, the incidence of persistent hydronephrosis over 3 months after RHPL was 15%, even without intra-operative ureteric injury.

  • [Title] Management of ureteric endometriosis associated with hydronephrosis: An Australian case series of 13 patients.
  • BACKGROUND: Hydronephrosis is a rare but serious manifestation of ureteric endometriosis.
  • Thirteen of the 126 women were identified as having ureteric obstruction at the time of their procedure and were included in the case series.
  • The point of ureteric obstruction was noted to occur most commonly at a small segment of distal left ureter, where it is crossed by the uterine artery (54%).
  • In all cases the hydronephrosis had resolved at six months follow up.
  • CONCLUSIONS: Our findings support the growing body of literature supporting ureterolysis as the optimal treatment for ureteric endometriosis causing moderate to severe ureteric obstruction.

  • [Title] Appearances of the circumcaval ureter on excretory urography and MR urography: A single-center case series.
  • OBJECTIVES: To describe Magnetic Resonance Urography (MRU) appearances of the circumcaval ureter, a rare congenital cause of hydronephrosis.
  • MATERIALS AND METHODS: Seven cases of circumcaval ureter, suspected on intravenous urography (IVU), underwent subsequent static MRU using heavily T2-weighted sequences.
  • RESULTS: The various appearances of circumcaval ureter on IVU and MRU were studied and compared.
  • The circumcaval portion of the ureter was especially well seen on axial MRU sections, though this portion was routinely not visualized on IVU.
  • In one case with a ureteric calculus, MRU also depicted a circumcaval course of the ureter, thus providing a complete diagnosis.
  • In yet another case, where a circumcaval ureter was suspected on IVU, MRU proved the actual cause of ureteric obstruction to be a crossing vessel.
  • CONCLUSION: Static MRU using heavily T2-weighted coronal and axial sequences can make or exclude the diagnosis of circumcaval ureter unequivocally.

  • This study investigated whether p53-dependent apoptosis is correlated with APE using an experimental rat model of hydronephrosis.
  • Hydronephrosis was induced by partial ligation of the right ureter.
  • Animals were sacrificed on scheduled time after unilateral ureteral obstruction and the expression of 8-OHdG, γ-H2AX, apoptotic proteins and APE was determined.
  • The accumulated p53 activated Bax and caspase-3 7 days after hydronephrosis induction and the resulting high levels of p53-dependent apoptotic proteins and γ-H2AX tended to decrease APE.
  • The intensities of 8-OHdG and caspase-3 immunolocalization significantly increased in obstructed kidneys than in sham-operated kidneys, although APE immunoreactivity increased after hydronephrosis induction.

  • [Title] Laparoendoscopic single-site repair of retrocaval ureter: first case report.
  • OBJECTIVE: We describe a case of retrocaval ureter treated with laparoendoscopic single-site surgery (LESS).
  • Radiological imaging demonstrated hydronephrosis, suggesting the presence of a retrocaval ureter.
  • RESULTS: Retrograde pyelogram confirmed a classic appearance for retrocaval ureter.
  • The entire ureter was mobilized posterior to the vena cava and transected at the caudal-most point where the dilated portion of the proximal ureter ended.
  • The distal ureter was repositioned lateral to the inferior vena cava and spatulated laterally.
  • The proximal ureter was spatulated medially.
  • At the 3-month follow-up, diuretic radionuclide scan revealed no evidence of obstruction of the right kidney and the patient was symptom-free.
  • CONCLUSIONS: Albeit challenging, LESS repair for retrocaval ureter is a feasible procedure that can be considered as a treatment option for this rare anatomic anomaly.

  • [Title] Retroperitoneal laparoscopic ureteroureterostomy for retrocaval ureter: report of 10 cases and literature review.
  • OBJECTIVES: To present our surgical techniques and experience with retroperitoneal laparoscopic ureteroureterostomy in 10 patients with retrocaval ureter and review the data on the laparoscopic management of retrocaval ureter published in English.
  • METHODS: A total of 10 patients with retrocaval ureter underwent laparoscopic ureteroureterostomy.
  • The retrocaval segment of ureter was mobilized and transposed anterior to the inferior vena cava.
  • At a mean follow-up of 52 months, remarkable improvement in the ureteral obstruction was observed.
  • CONCLUSIONS: Our results indicate that retroperitoneal laparoscopic ureteroureterostomy is a safe and effective procedure, and an excellent minimally invasive treatment option for retrocaval ureter.
  • Moreover, a thorough review of published data supports our viewpoint that laparoscopic surgery should probably be the first-line treatment for retrocaval ureter.

  • [Title] Double obstruction of ureter: A diagnostic challenge.
  • INTRODUCTION: Isolated obstruction of the ureteropelvic junction and the vesico-ureteric junction are the two most common causes of hydronephrosis in a pediatric population.
  • Here, we discuss the problems we faced when we encountered these two anomalies in the same ureter and the way in which we managed them.
  • AIM: To assess the difficulties in diagnosis of pediatric patients who present with both ureteropelvic junction obstruction (UPJO) and vesico-ureteric junction obstruction (VUJO) in the ipsilateral ureter and their management protocol.
  • Out of 254 children who were diagnosed to have hydronephrosis due to UPJO in our institute, 5 patients (in the age range of 5 to 10 years) had both UPJO and VUJO in the ipsilateral ureter.
  • All patients were suspected of having double obstruction during pyeloplasty when appropriate size double J stent could not be negotiated through the vesicoureteric junction into the bladder.
  • CONCLUSION: Children with double obstruction of the ipsilateral ureter present as a diagnostic dilemma.
  • Early diagnosis can be made if this condition is kept in mind while treating any hydronephrosis due to UPJO or UVJO.

  • We report a 7-year-old boy who had antenatally diagnosed and postnatally confirmed asymptomatic right congenital hydronephrosis secondary to ureteropelvic junction obstruction with the anteroposterior diameter ranging from 7 to 15 mm on serial ultrasound scans till the age of 6 years.
  • Our case revealed that prenatally detected hydronephrosis may worsen after spontaneous postnatal improvement and a polyp acting as a flip valve may produce intermittent hydronephrosis and symptoms later in life.

  • [Title] Interferon-γ improves renal interstitial fibrosis and decreases intrarenal vascular resistance of hydronephrosis in an animal model.
  • OBJECTIVES: To investigate the effect of interferon (IFN)-γ administration on renal interstitial fibrosis (RIF) and intrarenal vascular resistance of diseased kidneys in a reversible unilateral ureteral obstruction (RUUO) animal model.
  • RUUO was induced by clamping the left ureter using a small polyethylene tube.
  • The obstruction was reversed seven days after the operation by removing the tube.
  • RESULTS: The obstruction was successfully reversed in all animals.
  • Ureteral obstruction induced few lesions in the contralateral kidneys, and IFN-γ administration had no significant effect on them, although it exerted an antifibrotic effect on the obstructed kidneys.
  • CONCLUSIONS: IFN-γ administration restored or preserved renal histology and hemodynamics in an animal model of renal fibrosis after surgical reversal of hydronephrosis.

  • [Title] [Retrocaval ureter based on a series of 16 cases].
  • INTRODUCTION AND OBJECTIVES: To analyse the postoperative results of surgical treatment for retrocaval ureter.
  • MATERIAL AND METHODS: The authors report a retrospective clinical study of a series of 16 patients (six women and 10 men) with a mean age of 38 years (range: 15-45 years) with retrocaval ureter treated between 1975 and 2005.
  • All patients were evaluated by the standard diagnostic protocol for the time and were treated by one of the following surgical techniques: resection of the ureter and renal pelvis to renal pelvis anastomosis; resection of the ureter and pyelo-ureteric anastomosis; resection of the ureter and oblique end-to-end uretero-ureteric anastomosis; nephrectomy.
  • Surgical revision was performed in one patient with resection of the ureter and reanastomosis, while anterograde dilatation of the stenosis was performed in the other patient.
  • All patients were reviewed at six months with a satisfactory result, corresponding to reduction of hydronephrosis and improvement of renal function.
  • CONCLUSION: Over the last 30 years, the diagnosis of retrocaval ureter has become more reliable and less invasive.

  • [Title] Combination of vesicoureteric reflux and vesicoureteric junction obstruction.
  • OBJECTIVE: This study analysed the association of vesicoureteric reflux (VUR) and vesicoureteric junction obstruction (VUJO) requiring surgical interventions in infants and children.
  • MATERIAL AND METHODS: Over 30 years (1975-2004) 423 infants and children were operated on because of VUR, 163 owing to VUJO and 25 patients (33 ureters) with a combination of VUR and obstruction of the vesicoureteric junction on the same side.
  • In one refluxing ureter, the obstruction was not diagnosed during subureteric endoscopic injection of the orifice.
  • In five of the 33 ureters, redo reimplantation was necessary because of obstruction (four ureters) or reflux (one ureter).
  • CONCLUSIONS: A combination of VUR and VUJO should be taken into consideration in a patient with proven reflux, where the ureter is dilated and tortuous and following urination the hydronephrosis and hydroureter persist or slowly decrease.

  • [Title] Metal ureteral stent for benign and malignant ureteral obstruction.
  • PURPOSE: Metal ureteral stents are a relatively new version of a device with a long history of relieving ureteral obstruction.
  • Metal stents are effective for relieving ureteral obstruction but success regarding patient tolerability has been variable.
  • MATERIALS AND METHODS: The charts of patients undergoing metal ureteral stent placement for chronic ureteral obstruction were reviewed.
  • Data collected included patient age, gender, diagnosis/cause of obstruction, laterality, duration of indwelling metal stent, number of routine metal stent changes, complications and early discontinuations or stent changes.
  • All metal stents were placed to relieve ureteral obstruction due to ureteral stricture, ureteropelvic junction obstruction, retroperitoneal fibrosis or extrinsic malignant obstruction.
  • There were 3 metal stent failures in 2 patients with malignant ureteral obstruction.
  • There were no complications, or early discontinuations or changes due to adverse symptoms, patient dissatisfaction, worsening renal function or progressive hydronephrosis.
  • CONCLUSIONS: Metal ureteral stents are effective for benign and malignant ureteral obstruction in the absence of urolithiasis.
  • Good tolerability and annual stent exchange make metal stents an appealing alternative for patients with chronic ureteral obstruction treated with indwelling ureteral stents.

  • [Title] Congenital ureteropelvic junction obstruction: physiopathology, decoupling of tout court pelvic dilatation-obstruction semantic connection, biomarkers to predict renal damage evolution.
  • The widespread use of fetal ultrasonography results in a frequent antenatally observation of hydronephrosis, ureteropelvic junction obstruction (UPJO) accounting for the greatest fraction of congenital obstructive nephropathy.
  • UPJO may be considered, in most cases, as a functional obstructive condition, depending on defective fetal smooth muscle/nerve development at this level, with lack of peristaltic wave propagation--aperistaltic segment--and, therefore, poor urine ejection from the renal pelvis into the ureter.
  • Some criticisms on tout court semantic renal pelvis dilatation-obstruction connection have been raised considering that the renal pelvis expansion isn't, in any case, linked to an ostructive condition, as it may be verified by diuretic (furosemide) renogram together with scintiscan-based evaluation of differential renal function.
  • In this regard, rather than repetitive invasive nuclear procedures that expose the children to ionizing radiations, an intriguing noninvasive strategy, based on the evaluation of urinary biomarkers and urinary proteome, can define the UPJO-related possible progress of parenchymal lesions, thus predicting which patients must require an obstruction correcting surgery and in which patients, instead, the hydronephrosis will spontaneously resolve.

  • [Title] Laparoscopic Anderson-Hynes pyeloplasty without symphysiotomy for hydronephrosis with horseshoe kidney.
  • INTRODUCTION: The objective of this study is to clarify whether symphysiotomy is an essential procedure combined with the laparoscopic pyeloplasty for the surgical treatment of ureteropelvic junction obstruction related to horseshoe kidney.
  • METHODS: We retrospectively reviewed five horseshoe kidney patients with symptomatic hydronephrosis who underwent laparoscopic transperitoneal Anderson-Hynes pyeloplasty without symphysiotomy between July 2002 and October 2011.
  • Anterior crossing vessels were observed in all cases, and four of them were defined as a principle cause of the obstruction.
  • Crossing vessels were transposed behind the ureter with ureteropelvic anastomosis at the anterior aspect of these structures.
  • Diuretic renogram showed that renal function of the side with hydronephrosis was unchanged, but diuretic excretion half-time was diminished in all cases.
  • CONCLUSION: The present data suggest that symphysiotomy can be avoided in many, if not all, cases of hydronephrosis related to horseshoe kidney.
