A retroperitoneal approach for transureteroureterostomy: a neglected and forgotten procedure.

Transureteroureterostomy in 17 consecutive cases is reviewed. Our technique of the operation (with retroperitoneal approach) is described. Stenosis of the recipient ureter or other complications did not develop in any of our cases. Based on our experience we continue to regard this procedure as an excellent means of urinary diversion for patients with unilateral lower ureteral lesions.
