PURPOSE As endoscopic treatment for vesicoureteral reflux (VUR) has increased, secondary ureteral reimplantation (UR) after failure of endoscopic treatment has increased. We studied the clinical feature and efficacy of secondary UR after failure of endoscopic treatment compared with primary UR. MATERIALS AND METHODS Eighty-one children who had UR for VUR were enrolled. Charts were reviewed re...

We present a case of refractory hemorrhagic radiation cystitis in a patient who failed conservative management and was unable to undergo operative urinary diversion secondary to multiple comorbidities. His management was complicated by recurrent obstruction of his nephrostomy catheters due to marked ureteral thrombus formation from blood refluxing into the ureters from the urinary bladder. We w...

Ureteral peristaltic mechanism facilitates urine transport from the kidney to the bladder. Numerical analysis of the peristaltic flow in the ureter aims to further our understanding of the reflux phenomenon and other ureteral abnormalities. Fluid-structure interaction (FSI) plays an important role in accuracy of this approach and the arbitrary Lagrangian-Eulerian (ALE) formulation is a strong m...

We aimed to study the safety and efficacy of the cystoscopy-assisted nonrefluxing ureteral reimplantation technique using submucosal tunneling during laparoscopic ureteroneocystostomy (UNC) with a psoas hitch in patients with distal ureter stricture after gynecologic surgery. We reviewed six female patients who underwent gynecological surgeries. All patients showed persistent postoperative dist...

INTRODUCTION Urine transport from the kidneys into the urinary bladder is one of the classical subjects of applied peristaltic transport theory with which the modeling of ureteral flow practically began [1]. In general, the ureteral flow is not purely peristaltic and includes a component which depends on the pressure difference between the renal pelves and the urinary bladder. Thus reflux might...

Congenital midureteral obstruction caused by a ureteral stricture, valve, or an adynamic segment, is an exceedingly rare entity. When encountered, it is generally misdiagnosed as megaureter or ureteropelvic junction obstruction. Two children with midureteral obstructions were seen over the last two years. One of these had an anatomical defecta midureteral stricture; the other had a physiologica...

Duplex kidney (DK) is the most common congenital abnormality of the urinary tract, with an incidence of around 0.82%1,2. Basis of duplex kidney formation by embryology is explained as development of two ureteral buds separately from a single mesonephric duct gives rise to a duplex kidney with complete ureteral duplication. On the other hand, bifurcation of a single ureteral bud proximal to the ...

PURPOSE to assess the results of the Lich-Gregoire procedure in the treatment of primary vesicoureteral reflux (VUR). MATERIALS AND METHODS In a 2.5-year period, 141 children with primary VUR underwent a vesicoureteral reimplantation using the Lich-Gregoire procedure in 101 patients (158 ureters) and the Cohen procedure in 48 patients (68 ureters). Patients were evaluated retrospectively in a...
