Objective:
The aim of this study is to evaluate the efficacy of primary cystoscopic transurethral incision (CTUI) in the management of paediatric ureteroceles. The secondary aim is to compare the efficacy of CTUI between simplex and duplex systems.
Patients And Methods:
This is a retrospective review of consecutive paediatric patients requiring surgical intervention for ureterocele. Data collected for analysis included demographics, diagnostic, pre-operative investigations, operative interventions and postoperative variables.
Results:
Over a 19-year period, 79 consecutive cases were identified, and 42 were male (53.2%). The mean follow-up was 6.7 years. Seventy-three (92.4%) cases underwent primary CTUI; 50 of these cases (68.5%) required no further procedures during the study period. Sixty-one cases were treated by endoscopic intervention alone (77.2%). Forty-one (51.9%) cases had a simplex system, and 38 (48.1%), a duplex system. There was no statistically significant difference in the efficacy of primary CTUI in simplex vs duplex systems. Of the 20 patients who had pre-operative and postoperative micturating cystourethrograms performed, seven (35%) developed de-novo postoperative vesicoureteric reflux after CTUI.
Conclusion:
Primary CTUI is a safe, minimally invasive procedure that is definitive in the majority of children presenting with a ureterocele that requires intervention. There was no difference in success of primary CTUI between simplex or duplex systems.
