Transurethral incision of ureteroneocystostomy strictures in kidney transplant recipients

To report the treatment of patients who presented with vesico-ureteric stricture after kidney transplantation, using a minimally invasive endourological approach.

Patients (10 men and four women, mean age 34 years, range 22-55) were assessed at presentation by serum creatinine level, ultrasonography and intravenous pyelography when the serum creatinine level was < 200 micromol/L. When there was hydronephrosis of the allograft a percutaneous antegrade pyelogram was taken, followed by inserting a nephrostomy. After decompression a stent nephrostomy was passed into the bladder and the strictures at the vesico-ureteric junction incised along the stent during cystoscopy.

All 14 patients were treated endourologically by an endoscopic incision through the bladder; 13 fared well and one died from sepsis and transplantation problems. The mean follow-up was 8 months.

Simple incision of the stricture via cystoscopy was safe and effective, and succeeded in most patients. The endourological management of ureteric lesions is feasible and is currently our first-line management of ureteric complications after kidney transplantation.
