Cope loop catheter for retrograde internal stenting of ureteroileal anastomotic strictures

[Treatment of stenosis in uretero-intestinal anastomosis]

We report our experience in the treatment of uretero-enteric anastomotic strictures. Our incidence in this complication is 3.8% in orthotopic bladder substitution and 8.3% in ileal conduict.

MATERIAL AND METHODS

We have treated this complication in 6 patients with orthotopic bladder substitution and 4 with ileal conduict. We tried to perform a dilatation with a high pressure balloon and to place a Double-J catheter.

RESULTS

In 4 cases we could not introduce the guidewire through the stricture because there was a total stop. In the others 6 cases, one is doing well without Double-J, another one did not tolerate the catheter and we performed an open surgical reanastomosis, 2 kept the catheters until their death due to metastases and the other two continue alive with their catheter periodically replaced.

CONCLUSIONS

The direct uretero-enteric anastomoses present less stenoses risk. Endourological techniques should be the first option in treatment of these patients.

Endoscopic transurostomy diathermy anastomotomy. A combined approach to uretero-ileal stenoses

Uretero-ileal stenosis is a recognised complication of ileal conduit urinary diversion. Two patients are described in whom a combination of fibreoptic conduitoscopy with standard endoscopic "biliary" sphincterotomy was used to treat anastomotic strictures. The technique of endoscopic transurostomy diathermy anastomotomy allowed the salvage of 3 renal units without the need for laparotomy or long-term indwelling ureteric stents.

Surgical versus endoscopic treatment of non-malignant uretero-ileal anastomotic strictures

The classical treatment of uretero-ileal anastomotic strictures after Bricker uretero-ileostomy is open surgical revision. Recent progress in endourology has provided a number of alternatives. The success rate of these endoscopic techniques is less than the success rate of the open surgical revision.
