[Experience with transrenal ureteral occlusion (author's transl)].

Closure of the ureter with a mixture of butyl-2-cyano-acrylate and lipiodol was performed for the palliative management of urinary incontinence in 4 patients (unilaterally in 3, bilaterally in 1), after urinary diversion had been provided by operative or percutaneous nephrostomy (inoperable vesico-(recto-)vaginal fistulas [2 patients] due to irradiated cervical carcinomas, contracted bladder due to irradiation [1 patient] and irradiated locally advanced prostatic carcinoma [1 patient]). In the first two patients the ureters were occluded by transurethral access using ureteral catheters followed in one case by dislocation of embolic material in the renal pelvis (without sequelae). The transrenal access for ureteral closure was employed in the two other patients using adjuvant balloon catheter occlusion. With this technique no complications were encountered. All patients were discharged free of complaints and completely dry. To achieve this result two patients had required a second ureteral embolisation.
