Cohen's technique is the standard treatment of vesicoureteral reflux in children. Its disadvantage is still the classic difficulty in subsequent retrograde ureteral access, requiring the use of percutaneous techniques in the treatment of kidney stones. We describe a novel surgical technique for retrograde catheterization of an adult ureter by a flexible ureterorenoscope, thereby facilitating th...

Sixty one patients with primary vesicoureteric reflux were treated by endoscopic injection of Mentor Polytef paste. Seventy six of the 94 treated ureters showed complete disappearance of vesicoureteric reflux after one injection. Eight refluxing ureters required a second injection, one required a third, and one a fourth. Six ureters showed improvement in the grade of reflux after the first inje...

PURPOSE Prevalence of ureter and kidney duplication is roughly 1 per 125 people, and is associated with vesicoureteral reflux to lower pole in about 45% of cases. From antireflux surgical principles viewpoint, standard antireflux surgeries can be performed in these kidneys without releasing ureters from each other. We studied the results of Gil-Vernet antireflux surgery in 12 patients with dupl...

OBJECTIVES To evaluate the prognostic value of initial direct radionuclide cystography (DRC) for spontaneous resolution of vesicoureteral reflux (VUR). METHODS Fifty-one children with initial diagnosis and 1-6 years' follow-up of VUR by DRC were enrolled in this study. VUR was graded according to the anatomic grading as (1) mild reflux corresponding to tracer just in ureter, (2) moderate refl...

Dear Editor: The ureteral stents are defined as devices that are inserted inside obstructive ureters to maintain patency. Ureteral obstruction caused by extrinsic compression is a challenge in the management of malignant diseases. First, adequate stent placement across an obstructed ureter does not necessarily guarantee urine patency. Moreover, the stent is poorly tolerated, severely impairing ...

OBJECTIVE To determine the incidence of urinary tract infection in those patients that we have used an ureteral double-J stent as internal diversion after urological procedures. MATERIAL AND METHODS We reviewed all the medical records of patients who had a ureteral double-J stent after a urological procedure from August 2007 to May 2013. We have analyzed the following data: age, gender, type ...

OBJECTIVES To assess the feasibility and results of the endoscopic treatment of vesicoureteral reflux (VUR) after a failed ureteral reimplantation. METHODS From January 1996 to October 2006, 28 patients underwent endoscopic treatment for VUR grade II to V persisting after open ureteral reimplantation. VUR was bilateral in 11 patients, for a total of 39 ureteral units (UU) treated. The endosco...

INTRODUCTION Urological complications after kidney transplantation may lead to graft loss. In this study, we retrospectively reviewed urological complications in 1,223 kidney transplantations that were performed at our institution. MATERIALS AND METHODS The occurrence of urological complications such as urine leakage, ureteral obstruction and vesicoureteral reflux (VUR) according to the diffe...

PURPOSE We report a technique and outcome of endoscopic trigonoplasty II (ET II), anti-reflux surgery via a transvesicostomy transurethral approach and discuss its usefulness. MATERIALS AND METHODS Fifteen female patients, aged 5 to 64, with 23 refluxing ureters (grade I : 5, II : 2, III : 14, IV : 2) underwent the ET II. The principle of this surgery is tightening the muscular backing and el...

Purpose: Partial resection of the distal ureter is commonly performed during reconstructive surgery in pediatric urology; particularly for correction of vesicoureteral reflux (VUR) and ureterovesical junction obstruction (UVJO). Many hospitals require pathologic examination of all excised tissues. We examined the pathologic findings in such specimens to evaluate the utility of this practice. Me...
