Most cases of hydronephrosis are caused by urinary tract obstruction. However, excessive polyuric syndrome rarely gives rise to non-obstructive hydronephrosis, megaureter, and a distended bladder. The authors report here on two cases of congenital nephrogenic diabetes insipidus (NDI) with severe bilateral hydronephrosis and megaureter. It is Interesting that the patients were symptomless except...

BACKGROUND Hydronephrosis is a common congenital condition. The detection of fetal hydronephrosis by ultrasound presents a treatment dilemma. This study aims to examine postnatal follow-up and treatment for hydronephrosis diagnosed prenatally. MATERIAL AND METHODS This was a retrospective study of 210 infants with hydronephrosis diagnosed at the Qilu Hospital (Shangdong, China) between January ...

BACKGROUND Vesicoureteral reflux is thought to predispose to urinary tract infection and renal scarring, and ureteral reimplantation in childhood remains the gold standard for its treatment. It has been reported that the risk of postrenal failure during pregnancy is increased among women with Politano-Leadbetter ureteral reimplantation. In previous case reports on patients with progressive hydr...

Inguinal hernias involving the ureter, a retroperitoneal structure, is an uncommon phenomenon. It can occur with or without obstructive uropathy, the latter posing a trap for the unassuming general surgeon performing a routine inguinal hernia repair. Ureteral inguinal hernia should be included as a differential when a clinical inguinal hernia is diagnosed concurrently with unexplained hydroneph...

Intrauterine contraceptive device (IUCD) is a common method of contraception among women because of its low cost and high efficacy. Perforations are possible resulting in multiple complications including urinary complications. Obstructive hydronephrosis and hydroureter is one of the main clinical concerns in genitourinary practice leading to radiological investigations for determination of the ...

Primary or idiopathic retroperitoneal fibrosis, first described by Ormond in 1948, is a rare and elusive diagnosis, requiring a high level of suspicion. Patients usually present with entrapment of retroperitoneal organs, the most common being the ureters, causing hydronephrosis and acute kidney injury. Here, we present the case of a 56-year-old male presenting for recurrent and intermittent scr...

BACKGROUND The purpose of the present paper was to evaluate the clinical features of primary vesico-ureteral reflux (VUR) in Thai children. METHODS Children with primary VUR attending in the Nephrology Division, Department of Pediatrics, Prince of Songkla University between 1987-2002 were studied. RESULTS Sixty-five girls and 60 boys with primary VUR were evaluated. Age of diagnosis was sig...

  The common use of maternal ultrasonography has increased the apparent incidence of neonatal hydronephrosis. Many of these cases are found to have partial obstruction at the ureteropelvic junction (UPJ). These patients are safely managed in our institution with careful observation and only occasionally require surgical intervention. The authors present two contrastin...
