Surgical management of ureteropelvic junction obstruction: Report of 32 cases

Objective: To evaluate the surgical management of ureteropelvic junction(UPJ) obstruction.Methods: Thirty-two cases of congenital UPJ obstruction were treated by Anderson-Hynes pyeloplasty.Double-J stents were used as internal stands and drainage.Results: All the obstructions were successfully relieved,hydronephrosis was greatly improved and no complications such as urinary infection,leakage of urine or restricture were noted at follow-up.Conclusions: Anderson-Hynes pyeloplasty is an efficient treatment for congenital obstruction of UPJ,and the use of double-J stent as internal stand and drainage can help recovery of kidney function,reduce the chance of UPJ restriction,and raise the rate of success.
