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...

Purpose: To present our experience of laparoscopic ureteral reimplantation using intracorporeal ureteral tapering for management of distal ureteral stricture. Materials and Methods: Between April 2005 and October 2008, six patients, including 3 children and 3 adults, underwent laparoscopic modified Lich-Gregoir type extravesical ureteral reimplantation for distal ureteral stricture. Significant...

BACKGROUND Ovarian vein syndrome is a rare cause of teral obstruction. In this report, we describe an unusual presentation of the syndrome successfully treated with laparoscopic techniques. METHODS The patient presented with a 12-month history of right flank pain and a right abdominal mass. The preoperative evaluation revealed renal malrotation, hydronephrosis, decreased renal function, and p...

Physiol. 277 (Renal Physiol. 46): F766–F772, 1999.—Unilateral ureteral obstruction (UUO) results in tubulointerstitial fibrosis of the obstructed kidney. In this study, we report the contribution of tumor necrosis...

Unilateral ureteral obstruction (UUO) results in tubulointerstitial fibrosis of the obstructed kidney. In this study, we report the contribution of tumor necrosis factor-α (TNF-α) to the fibrosis that develops after ureteral obstruction. Mice in which individual TNF-α receptors TNFR1 or TNFR2 had been genetically knocked out were used, and results were compared with mice of C57Bl/6 background a...

We report a case of an indwelling inferior vena cava filter that penetrated the IVC wall after Whipple's pancreatico-duodenectomy procedure performed in a patient with ampullary carcinoma, resulting in right ureteral injury and obstruction with subsequent hydroureter and hydronephrosis. This was incidentally discovered on a computed tomography scan performed as routine follow up to evaluate the...

Fungus balls rarely cause upper urinary tract obstruction, and they are most often found in patients with diabetes mellitus or impaired immunity. The computed tomography (CT) findings of fungal bezoars of the urinary tract are nonspecific and have rarely been described, while in most cases, radiolucent filling defects are observed on excretory or retrograde urography. Here, an unusual case of a...

Postpartum ovarian vein thrombosis (POVT) is an uncommon disease and it may complicate streptococcal group B infection of the vagina and endometrium. Obstruction of the right ureter is an uncommon complication of POVT. We present a case of POVT complicated by thrombus extension in the inferior vena cava and ureteral obstruction with urinary leakage, and outline the clinical presentation, radiol...

Objectives. We compared outcome and complications after uncomplicated ureteroscopic treatment of distal ureteral calculi with or without the use of ureteral stents. Materials and Methods. 117 patients, prospectively divided into three groups to receive a double j stent (group 1, 42 patients), ureteral stent (group 2, 37 patients), or no stent (group 3, 38 patients), underwent ureteroscopic trea...
