Clinical Study on Treatment of Ureteropelvic Junction Obstruction with Dismembered Pyeloplasty

Objective To summarize the experience on diagnosis and treatment of ureteropelvic junction obstruction(UPJO) with dismembered pyeloplasty.Methods The clinical data of 36 patients with UPJO were retrospectively analyzed.Within these 36 patients,there were 21 patients with ureteropelvic junction obstruction,8 patients with high ureteropelvic junction obstruction,4 patients with compression from crossing blood vessels,and 3 patients with compression from fiber cables.All the patients underwent dismembered pyeloplasty.Results All the patients were examined with B-ultrasonography and IVP and followed up from 12 to 64 months,with the average follow-up survey time of 36 months.Hydronephrosis completely disappeared or significantly subsided in 32(88.9%) patients.3(8.3%) patients with hydronephrosis had no significant change,and 1(2.8%) patient with hydronephrosis became more serious than before.Conclusions Dismembered pyeloplasty is a good choice for the patients with ureteropelvic junction obstruction.
