Abstract:
Objective To investigate the experience of diagnosis and management of coexisting ureteropelvic junction obstruction (UPJO) and nonreflux megaureter (NRM).Methods The retrospective study of UPJO with NRM was based on 10 years information retrieved from January 2005 to December 2015.The data of 13 patients (8 males and 5 females) were available and recorded.Mean age at surgery was 3.7 years old (range 1.8 to 14 years).The diagnosis and mangement were summarized.Coexisting ureterovesical junction obstruction (UVJO) and vesicoureteral reflux,iatrogenic stricture and vesicoureteral reflux were excluded.Intravenous pyelography,voiding cystourethrography,ultrasound and CT reconstruction were performed before operation.Only six patients had an accurate diagnosis as UPJO with UVJO before surgery.Pyeloplasty was the initial surgical management choice for 10 patients,and ureteroneocystostomy in 3 patients.Results UVJO were diagnosed with pyelography techniques in 3 patients after pyeloplasty,while 4 were diagnosed as nonreflux and nonobstruction megaureter.Of the 10 patients who underwent initial pyeloplasty,additional ureteroneocystostomy was required in 3 and the prognosis was good.Additional pyeloplasty was required in 2 of the 3 patients who initially underwent ureteroneoeystostomy.Mean follow-up time from last operation was 23.3 months (6-53 months),the overall prognosis was good.Conclusions It is often difficult to correctly diagnose coexisting UPJO and NRM.In patients with UPJO,it is highly recommended nephrostomy radiography after pyeloplasty to evaluate the distal ureterovesical junction.Initial pyeloplasty is always recommended as first-line therapy.Additional ureteroneocystostomy was required when hydroureteropelvic was aggravated.
