Body mass index as a predictive value for complications associated with reconstructive surgery in patients with myelodysplasia.

Purpose: Patients with myelodysplasia often have urological pathology, with 25% to 40% requiring reconstructive procedures to achieve urinary and/or fecal continence. Complication rates from these major reconstructive procedures range between 10% and 50%. Additionally many of these patients have significant comorbidities, including a nonambulatory status that leads to an increased body mass index.

Endoscopic injection of submucosal bulking agents for the management of incontinent catheterizable channels.

Background: Urinary and fecal continence can be achieved by constructing catheterizable continent channels that provide access to the bladder and bowel. Some patients develop persistent stomal leakage. A minimally invasive method of injection with a bulking agent for treatment of stomal incontinence was evaluated.

Use of second look nephroscopy in children undergoing percutaneous nephrolithotomy.

Purpose: We determined the rate of stone clearance in children following percutaneous nephrolithotomy, endoscopic assessment of residual stone and the judicious use of second look nephroscopy.

Materials And Methods: We retrospectively reviewed the charts of all children undergoing percutaneous nephrolithotomy from 1996 to 2007. Cases were reviewed for pertinent details including preoperative and postoperative imaging, specifics of the procedure and followup.

Occurrence of urinary tract infection in children with significant upper urinary tract obstruction.

Objectives: Ureteropelvic junction obstruction and obstructive megaureter are common causes of upper urinary tract obstruction. Recent data have demonstrated that the rate of urinary tract infection (UTI) among children with upper tract obstruction not treated with prophylactic antibiotics is >36%. The aim of this study was to evaluate the occurrence of UTI in our patients with ureteropelvic junction obstruction and megaureter to better assess the role of prophylactic antibiotics.
