In infants and young children with suspicion of genitourinary tract anomalies, ultrasonography (USG) is usually the first imaging modality. Advantages of USG are well described. In the evaluation of complex congenital urogenital anomalies, ultrasound examination needs to be tailored according to the clinical suspicion and to yield maximum information. Primary megaureter is a congenital anomaly, which is associated with dilatation of ureter above an adynamic segment at the vesicoureteric junction (VUJ). Two different types are described in the literature: refluxing and obstructive...

BACKGROUND: The gold standard treatment for primary obstructive megaureter (POM) with declining renal function, worsening obstruction, or recurrent infections is ureteral re-implantation with or without tapering. In infants, open surgery can be technically demanding and associated with significant morbidity. We conducted a systematic review of the literature with special interest in endoscopic management of POM and its outcomes. METHODS: A search was conducted of the MEDLINE/Ovid, PubMed, Embase, and Web of Science databases...

BACKGROUND: Open neoureterocystostomy is the traditional surgical treatment for primary obstructive megaureter (POM). Endoscopic balloon dilation is a new minimally invasive alternative. It has been shown to be a safe and effective endoscopic procedure over short-term follow-up; however, few studies have shown its long-term efficacy. OBJECTIVE: The aim of this study was to evaluate the long-term results and complications of balloon dilation for the treatment of primary obstructive megaureter in infants...

A unilateral megaureter was found in an elderly female cadaver during routine dissection. The left proximal ureter, which was thick and convolute, descended and entered into the pelvic cavity, where the distal ureter was attached to the posterior pelvic wall at the inlet level. Removal of connective tissue surrounding the attached region revealed ureteric entrapment in the sacroiliac joint. The ipsilateral kidney, from which the megaureter originated, showed no pelvicalyceal dilatation. In contrast, the left kidney was enlarged, weighing 24% more than the right kidney...

PURPOSE: The Urinary Tract Dilation grading system for prenatal hydronephrosis was introduced to address potential shortcomings of the Society for Fetal Urology classification. Hydronephrosis resolution is an important patient outcome and is frequently discussed during family counseling. We compared these 2 grading systems and their ability to predict time to hydronephrosis resolution. MATERIALS AND METHODS: We prospectively screened 855 patients with prenatal hydronephrosis due to ureteropelvic junction obstruction-like hydronephrosis, nonrefluxing primary megaureter or vesicoureteral reflux between 2009 and 2015...

INTRODUCTION: Duplication of the upper urinary tract is one of the most common congenital urological anomalies. In patients with critically decreased or lost function of one of the renal segments, heminephrureterectomy is usually the treatment of choice. Until recently, this was an open surgery; in cases of complete removal of the ureter, an additional incision in the iliac region was required. Currently, heminephrureterectomy is increasingly performed laparoscopically. We report the experience in laparoscopic heminephrureterectomy (LHNUE) in 10 clinics in Russia and Belarus...

Down syndrome (DS) is often associated with cardiac malformations, so that kidney damage is little known. The objective of this study was to present the diversity of renal abnormalities and their potential progression to chronic renal failure. Among congenital abnormalities of the kidney and urinary tract (CAKUT) abnormalities appear to be frequent: pyelectasis, megaureters, posterior urethra valves, as well as renal malformations such as renal hypoplasia, horseshoe kidney, or renal ectopia. Contributing factors to acute kidney failure have been described in patients with DS: bilateral lesions and minor renal injury, such as glomerular microcysts, tubular dilation, and immature glomeruli...

BACKGROUND: Primary obstructive megaureter is relatively uncommon in adults. This condition usually regresses spontaneously or is treated during infancy. It can remain asymptomatic for decades until adulthood when symptoms may manifest in the event of complications or during a routine radiologic imaging. Primary obstructive megaureter has been reported to favor stone formation in the upper urinary tract. CASE PRESENTATION: We present the case of a 35-year-old Moroccan man who had a 10-year history of intermittent left flank pain and hematuria...
