[Long-term results of angioplasty balloon dilatation of stenosed uretero-digestive anastomoses. Effect of prolonged pattern with large caliber prosthesis].

Unlabelled: 16 strictured uretero enteric anastomoses were dilated and stented for 4 months with a large size stent (18F in fifteen cases and 14F in one case). All the patients had undergone a radical cystoprostactectomy, had received radiotherapy prior to surgery. The length of the stenosis did not exceed 3 cm in all cases. All the stenoses occurred within 2 years following the removal all of the stent.
Results: 6 cases (37%), have a patent anastomosis, 18 to 36 months following removal of the stent. Most of the recurrences occurred within six months following removal of the stent. We recommend a long term stenting with a large size stent to obtain long term patency of dilated anastomotic strictures.
