1. local treatment: local treatment can be used to solve the pathological changes in the obstruction site, such as adhesion separation, fibrous band cutting, vascular transposition anastomosis, stone removal, etc. When the local compression time is too long and the local development of ureter is seriously damaged, this section of ureter should be removed and anastomosed again.
2. When the obstruction has caused severe hydronephrosis, you must first make a fistula and drain.
3. Plastic surgery: You must master the main points of plastic surgery:
① Ureteropelvic anastomosis was performed at the lowest point of the renal pelvis.
② The ureteropelvic anastomosis should be funnel-shaped.
③ When repairing, the surrounding fibers, adhesions and scar tissues should be removed, but the blood supply should not be damaged.
④ Resection of redundant renal pelvis wall to maintain a certain renal pelvis tension. If the hydronephrosis is too large, the thin renal cortex can be inverted, folded and fixed to reduce the renal internal volume.
⑤ To reduce the leakage of urine at the anastomotic site, double pigtail catheters can be placed. In order to avoid scar fibrosis caused by urine leakage and hemolysis stagnation around the anastomosis, a negative pressure suction tube can be placed outside the anastomosis to fully drain.
⑥ There are many plastic surgery methods, but at present, considering the etiology and pathology, it is considered that it is better to remove the diseased segment and then anastomose it.
