[Cutaneous transuretero-ureterostomy or cutaneous Y-ureterostomy. Apropos of 14 cases].

Cutaneous transureterostomy was performed in 14 patients, this bypass procedure being necessary in 9 cases for neoplasm (7 after total cystectomy) and in 5 patients for non-neoplastic lesions. The simplicity of this method is emphasized, particularly when compared with Bricker's operation, beneficial effects with respect to the comfort of the patient being similar. However, at least one ureter must be dilated: one failure of treatment was due to narrow ureters and a repeat operation was necessary to exteriorize each ureter on to the skin. The essential problem concerns the skin stoma, if an apparatus is to be fitted without a catheter. In 8 of 12 patients the cutaneous ureterostomy remained patent without artificial assistance. Two operated cases required ureteral catheters, while two others had prosthetic replacement of the foot of the ureterostomy in Y. One patient died after cystectomy for cancer. A new cutaneous and aponeurotic reconstructive mode appears capable of guaranteeing more consistent results.
