OBJECTIVES Although valve ablation is the treatment of choice for patients with posterior urethral valves, debate continues as to the role of urinary diversion. We sought to retrospectively compare the clinical and radiologic outcomes between valve ablation and urinary diversion for patients with posterior urethral valves. METHODS We retrospectively reviewed the records of 50 consecutive pati...

Obstructive uropathy can be caused by urolithiasis, fibrotic ureteral stricture, inflammatory ureteritis with polyp formations, ureteral malignancy and various forms of external compression. Ureteral herniation is a relatively rare cause of obstructive uropathy and has been reported with herniation sites including inguinal canal, femoral canal and sciatic foramen. Most ureteral herniations occu...

OBJECTIVE Antenatal hydronephrosis is diagnosed in 1% to 5% of all pregnancies; however, the antenatal and postnatal management of hydronephrosis varies widely. No previous studies define the risk of postnatal pathology in infants with antenatal hydronephrosis. Our objective was to review the current literature to determine whether the degree of antenatal hydronephrosis and related antenatal ul...

PURPOSE The American Urological Association established the Vesicoureteral Reflux Guideline Update Committee in July 2005 to update the management of primary vesicoureteral reflux in children guideline. The Panel defined the task into 5 topics pertaining to specific vesicoureteral reflux management issues, which correspond to the management of 3 distinct index patients and the screening of 2 di...

BACKGROUND to determine the usefulness of Doppler ultrasound measurement of resistive index (RI) in differentiating obstructive from non-obstructive hydronephrosis in children. METHODS From August 2011 to November 2012, renal Doppler assessments of the intra-renal renal arteries were performed on 16 children (19 kidneys) with congenital hydronephrosis. the independent t-test was used to asses...

the outcome and proper management of fetal hydronephrosis have not been completely defined. the purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. in a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more...

Objectives: To describe the maternal and fetal characteristics of isolated antenatal hydronephrosis (ANH), to address parental concerns by providing local data based on the fetal renal pelvis anteroposterior diameter (APD), and to determine the most effective APD cutoff in the second and third trimester for prediction of postnatal urological outcome. Methods: A retrospective review of all cases...

INTRODUCTION Prostatic hyperplasia is the most frequent tumor in men older than 50 years of age. Bilateral hydronephrosis secondary to benign prostatic hypertrophy is a rare condition most often due to vesicoureteral reflux. Herein we report a case of a patient with bilateral hydronephrosis with distal ureter obstruction caused by detrusor hypertrophy due to prostatic hyperplasia, our analysis ...
