title: [Influence of leakage of the bladder mucosa on the results of external ureterovesicoplasty (author's transl)].
abstract: The significance for the results of external ureterovesicoplasty of damaging the vesical mucosa was investigated in rabbits. On one side, the submucosal ureter was lengthened by myotomy, and on the other side, an additional incision of the mucosa caused the ureter to be shifted intravesically. In 10 animals, results were symmetric; in 7 cases, stasis occurred on the side of the sunken ureter; 2 animals showed marked hydronephrosis on the Grégoir side. Increased mobility and thereby kinking of the intravesical ureter and inflammatory reaction on temporary leakage of urine are shown to be the causes of worse results following mucosa leakage. As consequence of the study importance of careful closure of any mucosal defect occurring during Grégoir operation is stressed.
