Surgery can treat pelvic-ureteral junction stenosis, but what are the postoperative complications of pelvic-ureteral junction stenosis?

Postoperative complications of ureteropelvic junction stenosis include severe hydrops. When a patient has hydronephrosis on both sides, it is necessary to distinguish which side has more severe hydronephrosis symptoms. Treatment should be carried out in stages, with the severe side treated first. This way, the symptoms of renal insufficiency can be avoided. After the surgery on one side is successful, the safety of the surgery on the other side can be increased. When necessary, the patient should be closely observed.

Usually if severe hydrops in the kidney is caused by ureteral stones embedded in the ureter, the patient needs to undergo percutaneous nephrostomy or an indwelling ureteral stent to relieve the hydrops until the kidney function recovers. Surgery will be performed later to remove the stones. If severe hydrops in the kidney is caused by a ureteral tumor, the patient needs to undergo laparoscopic radical ureteral tumor resection.
