[Free peritoneal patch grafts in surgery on renal pelvis and ureter (author's transl)].
36 operations of the renal pelvis or ureter were carried out in 35 patients. In all these cases a split stenosis or a tissue defect were covered by free peritoneal patches. Urographic controls of 30 patients showed 29 good or very good results. The following statements can be made: 1. In cases of a secondary scarred stenosis, of renal pelvic or ureteral wall defects, plastic operations of intrarenal pelvis of transsinus operations of staghorn calculi the splitting with splinting and covering by autologous tissue seems to represent a suitable operation. -- 2. As material the renal capsule, the venous wall and the peritoneum are suitable. -- 3. In cases of severe ureteral stenoses, which have to be resected, especially in cases of considerable differences of the ureteral lumen, the semicircular suture with covering should be preferred to the circular suture. -- 4. The covering of the defects by patches of autologous material reduces the time of the postoperative urinary diversion with all its dangers and the period of hospitalization. -- 5. In cases of a short covered stenoses (up to 4 cm) postoperative disturbance of the transport or urine was observed only once. The results of stenoses, longer than 4 cm, cannot yet be evaluated.
