If ureteropelvic junction obstruction is due to ureteral stricture, then ureteral stricture is generally divided into congenital and acquired. Congenital disease usually occurs at the junction of renal pelvis and ureter. This problem can be solved by surgical resection of stricture, pyeloplasty and bladder-ureter junction (bladder entrance stenosis).

Therefore, it is generally considered that the possibility of recurrence after ureteropelvic junction obstruction surgery 10 years is not great. However, patients with a history of ureteropelvic junction obstruction must be reviewed regularly. Urinary ultrasound is usually done to determine whether there is hydronephrosis. Once the problem is found, surgery should be performed immediately to relieve obstruction and hydronephrosis.
