OBJECTIVE To explore the method of building a stable urethral stricture (US) model in New Zealand white rabbits. METHODS Through 10X magnification optical microscope, a resection of 1.0cm urethral mucosa was made in 6 male rabbits and other 6 male rabbits were controlled. After 60 days, the rabbits were evaluated with urethrography, urethral pressure profile (UPP) and histology. RESULT Uret...

A 55-year-old woman underwent a low anterior resection for rectal cancer 7 years earlier at a different hospital. Thereafter, she often had such symptoms as abdominal pain, frequent bowel movements, and constipation. We considered postoperative bowel adhesion to be the cause of these symptoms, and a laparoscopic adhesiotomy was therefore performed twice. However, the symptoms did not substantia...

During orthotopic liver transplantation (OLT), biliary tract perfusion occurs with hepatic artery reperfusion (HARP), commonly performed after the portal vein reperfusion (PVRP). We examined whether the average time interval between PVRP and HARP impacted on postoperative biliary strictures occurrence. Patients undergoing OLT from 2007 to 2009 were included if they were ≥18 years old, had survi...

With the advent of new technology, the treatment for ureteric stricture has moved from open surgery to endoscopic procedures. Our goals were to review and determine the prognostic factors for success of laser endoureterotomy for ureteric stricture. This is a cross sectional study for all cases that underwent laser endoureterotomy in a single centre from 2002 to 2009. Standard treatment in this ...

INTRODUCTION A simple technique to dilate urethral stricture using guide wire and sheath dilator has been described in pediatric urology. The aim of this study was to report the long-term outcome of the children who underwent dilation of the urethral stricture using guide wire and sheath dilator. MATERIALS AND METHODS From 1999 to 2004, a total of 52 children with documented urethral strictur...

PURPOSE We evaluated the success rate of direct vision internal urethrotomy as a treatment for simple male urethral strictures. MATERIALS AND METHODS A retrospective chart review was performed on 136 patients who underwent urethrotomy from January 1994 through March 2009. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, third, fourth and fifth ur...

Four patients and the relevant findings are included in the Table. There was no history of an impacted foreign body in any patient. The stricture in the three women (Table) was severe and extensive; its upper end was at or just below the cricopharyngeus, so that the stenoses did not affect the post-cricoid space. When examined with the oesophagoscope, the stricture was very tight and could only...

INTRODUCTION Urethral stricture refers to anterior urethral disease, a scarring process involving the spongy erectile tissue of the corpus spongiosum, also referred to as spongiofibrosis 1 . 80% of strictures that are secondary to instrumentation occur at the membranous urethra. The other 20% generally occur at the penoscrotal junction. A study done by Palminteri et al 2 on 1439 patients with u...

PURPOSE To compare urethral stricture rates in comorbid patients undergoing plasmakinetic transurethral resection of the prostate (PK-TURP) and monopolar transurethral resection of the prostate (M-TURP) for benign prostatic hyperplasia. METHODS The data of 317 patients with comorbidities undergoing either PK-TURP or M-TURP from September 2008 to December 2012 were retrospectively evaluated. P...

Fifteen consecutive patients presenting with dysphagia due to aluminum phosphide (AP)-induced esophageal strictures were studied retrospectively to elucidate the natural history of AP-induced esophageal strictures and to evaluate the efficacy of bougie dilation. The median time lag between consumption of AP and occurrence of dysphagia was 3 weeks. All patients had a single stricture and could b...
