Reimplantation of the ureter in a transtrigonal mucosal groove

Abstract

Reimplantation of the ureter into a groove of the bladder mucosa has been used to simplify the procedure of reimplantation and overcome problems in trabeculated bladders by obviating the creation of a submucosal tunnel. Further experience is presented regarding this procedure on 40 ureters of patients with unilateral or bilateral vesicoureteric reflux, ureteric orifice(s) stenosis, bladder diverticula and posterior urethral valves submitted to simultaneous resection. Intra-operative observations, post-operative cystography and long-term results led to the conclusion that the procedure is technically easy, facilitates reimplantation in trabeculated bladders, safeguards the valve mechanism by preventing vesicoureteric reflux and shortens hospitalisation time.
