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...

INTRODUCTION To determine the feasibility, safety, and efficacy of diagnostic and therapeutic ureteroscopy in renal allograft ureters. MATERIALS AND METHODS We reviewed 1560 consecutive renal allografts have been preformed between June 1989 and February 2002.Twenty-eight patients (1.8%) had indication for endoscopic procedure on allograft ureter. Six patients had obstructive ureteral calculi ...

OBJECTIVE Discolored ureteral stents are sometimes encountered in daily clinical practice; however, the mechanism(s) underlying the development of discolored ureteral stents remain unknown. In this study, we retrospectively analyzed the characteristics of discolored ureteral stents based on the results of a urinalysis and urine culture. MATERIALS & METHODS We identified a total of 26 patients...

Inverted-Y ureteral duplication is one of the rarest anomalies of ureteral branching. We encountered a 20-year-old female patient with persistent incontinence even after nephrectomy for ectopic ureteral insertion into the vagina. She had inverted-Y ureteral duplication between the bladder and vagina, and urine was being transported from the bladder to the vagina. To the best of our knowledge, t...

Robotic-assisted ureteral reimplantations were performed on 3 patients at a single institution, 2 with Boari flap and psoas hitch and 1 with psoas hitch alone. These were for urothelial carcinoma of the distal ureter, ureteral obstruction caused by distal ureteral endometriosis, and ureteral transaction during gynecologic surgery. We used intraoperative ureteroscopy to confirm tumor margins as ...

INTRODUCTION This work evaluates the results of ureteroscopic treatment of impacted ureteral stones with a pneumatic lithotripter. MATERIALS AND METHODS From March 1997 to May 2002, 42 patients with impacted ureteral stones were treated by retrograde ureteroscopic pneumatic lithotripsy. Twenty-eight patients were female and 14 were male. The stone size ranged from 5 to 20 mm. The ureteral sit...

INTRODUCTION Vesico-ureteral reflux (VUR) is a common congenital anomaly of the urinary tract in the pediatric population, existing controversy regarding its management. Patients selected for treatment options are offered, from endoscopic injection of substances sub-ureteral to ureteral reimplantation surgery. OBJECTIVE To evaluate the use of the laparoscopic surgical technique for the treatm...

We report a successful surgical intervention to repair bilateral ureteral strictures in a child with juvenile dermatomyositis (JDM) and ureteral calcinosis. This is the fourth reported case in medical literature. A 9-year-old-girl with severe JDM, a rare connective tissue disease characterized by skin and muscles vasculitis, was under immunosuppressive therapy. In the course of the disease, she...

Ureteral activity during the intravesical infusion was examined by urometry and electro-ureterograpby in 12 normal persons and a patient with vesico-ureteral reflux. The urometrograms and eloctro-uroterograms in normal persons indicated that when the bladder was distended with physiologic saline solution,the ureteral peristalsis responded so as to overcome the increased intravosical pressure. I...
