Endourologic therapy of bladder calculi in simultaneous kidney-pancreas transplant recipients.
OBJECTIVE
To identify the incidence and the success of endourologic therapy for symptomatic bladder-related calculi in simultaneous kidney-pancreas (SPK) transplant patients with bladder drainage.


METHODS
A retrospective review of 300 SPK transplant patients with bladder drainage, treated at the University of Wisconsin, Madison from December 1985 to November 1995, is presented. A 3% incidence of bladder calculi was identified. All patients underwent cystolitholapaxy using electrohydraulic lithotripsy and endoscopic suture removal. Follow-up ranged from 15 to 86 months.


RESULTS
A 100% stone-free rate was achieved after cystolitholapaxy and endoscopic suture removal. Two patients (22%) developed postprocedural urinary tract infections. No pancreaticoduodenocystotomy leaks or further complications were identified.


CONCLUSIONS
SPK transplant patients with nonabsorbable sutures used for the duodenocystotomy anastomosis are at an increased risk for bladder calculi. Cystolitholapaxy with electrohydraulic lithotripsy is a safe and effective treatment for these suture-related stones.
