PURPOSE: Two accepted open surgical techniques exist for lower urinary tract reconstruction for ureteroceles, that is complete excision/enucleation and marsupialization/partial excision. To our knowledge it is currently unknown whether 1 method offers better clinical outcomes. We sought to answer this question. MATERIALS AND METHODS: We retrospectively reviewed the records of patients who underwent open surgical repair for ureterocele at 3 academic institutions. The 2 groups (complete excision vs marsupialization) were compared for each clinical outcome, including ongoing vesicoureteral reflux, new bladder diverticulum, hydronephrosis, continence, urinary tract infection and voiding dysfunction. Each clinical outcome was analyzed for independence from the surgical method. RESULTS: A total of 33 cases of complete excision and 24 of marsupialization were collected. The excision and marsupialization groups were similar with respect to patient age at surgery, gender and average followup (55 and 38 months, respectively). Most ureteroceles were unilateral and part of a duplicated system. Approximately half were intravesical and vesicoureteral reflux was the primary indication for surgery. In the excision group 82% of ureteroceles were previously punctured but only 50% were punctured in the marsupialization group (p = 0.09). Postoperatively the groups did not differ significantly in terms of ongoing vesicoureteral reflux (13% and 14%), bladder diverticulum (3% and 9%), continence (100% and 95%), urinary tract infection (43% and 46%) or voiding dysfunction (24% and 25%, respectively). They varied significantly in terms of improved or stable hydronephrosis (70% vs 91%, p = 0.05). CONCLUSIONS: When performing lower urinary tract reconstruction for ureterocele, this study demonstrates that the choice of complete excision vs marsupialization/partial excision does not appear to differentially affect clinical outcomes.
