CATHETER MODIFICATION FOR TRANSRENAL TEMPORARY TOTAL URETERAL OBSTRUCTION - THE OCCLUSIVE NEPHROURETERAL CATHETER

When temporary diversion of urine is desired and a simple nephrostomy catheter is insufficient or passage of a ureteral stent cannot be achi eved, a standard 8 or 10 F nephroureteral catheter can be modified to provide a single nephrostomy drainage catheter with an occluded ureter al segment that provides total diversion of urine. The ''occlusive'' n ephroureteral catheter is exchangeable over a guide wire as necessary. When healing of the ureteral or bladder process has occurred, the cat heter is removable, allowing restoration of normal urine flow.
