The use of the detrusorrhaphy for vesico-ureteric reflux: the way forward?

To assess the outcome of all detrusorrhaphies carried out for simple single-system vesico-ureteric reflux (VUR) in children at one institution over a 4-year period.

Twenty-nine patients (11 boys, 18 girls, 43 renal units; mean age at presentation 23 months; range, antenatal to 72 months) were analysed in two groups. Group 1 comprised those undergoing asynchronous bilateral procedures (two patients, four units) and unilateral procedures (15 patients, 15 units), and group 2, those undergoing synchronous bilateral procedures (12 patients, 24 units). The mean (range) follow-up was 17 months (6-39) and 15 months (7-24), respectively.

Three patients had antenatal hydronephrosis related to VUR post-natally and 26 had urinary tract infections (13 recurrent, one with haematuria, seven 'breakthrough', one with calculi and four with enuresis). The mean age at operation was 54 months (range 14-167). The mean (range) duration of anaesthesia was 69 min (40-120) in group 1 and 80 min (65-120) in group 2. All patients were catheterized urethrally for a mean (range) duration of 3 days (2-4) in group 1 and 5 days (2-15) in group 2 and the mean hospital stay was 3 days (2-6) and 6 days (4-16), respectively. Post-operative complications occurred in 14 patients including one bladder spasm, five urinary tract infections, two with urinary retention, three with haematuria and one each of pneumonia, epididymo-orchitis, anuria, failure to stent and conversion to Cohen reimplantation. Operative success and clinical success were similar within groups but differed between groups, although not significantly (15 of 17 in group 1 and eight of 12 in group 2).

Unilateral but not synchronous bilateral detrusorrhaphy seems an appropriate surgical treatment for VUR.
