title: Ureteropelvic junction obstruction: relation of etiology and age at surgical repair to clinical outcome.
abstract: Ureteropelvic junction (UPJ) obstruction is a congenital anomaly either caused by intrinsic narrowing of the upper ureter or by extrinsic pressure on the ureter caused by aberrant vessels or fibrous bands. We reviewed 121 cases of pyeloplasties performed in our department for UPJ obstruction. The cases were grouped by age and by the underlying pathology. Postoperative urographic evaluation showed that dismembered pyeloplasty was successful in 98.4% of the patients, with no significant difference between age groups. Persistence or recurrence of preoperative symptoms occurred in some patients (16.6%). Extrinsic obstruction of the ureter was associated with better postoperative clinical results and less recurrence of symptoms.
