Transureteroureterostomy is a surgical procedure that involves the anastomosis, or connection, of one ureter to the contralateral ureter, which is the ureter on the opposite side of the body. This procedure is distinct from ureteroureterostomy, where two segments of the same ureter are joined. Transureteroureterostomy is typically indicated for patients suffering from conditions such as ureteral stenosis, obstruction, or injury that affect the normal function of the ureters. The procedure aims to restore urinary flow by bypassing the affected segment of the ureter, thereby facilitating the drainage of urine from the kidneys to the bladder. During the operation, careful attention is given to preserving the surrounding tissues and blood supply to ensure optimal healing and function post-surgery. The technique involves creating a retroperitoneal tunnel and mobilizing the healthy segment of the ureter to connect it to the contralateral ureter, which is essential for maintaining urinary continuity and function.
