Foreskin reconstruction at the time of single-stage hypospadias repair: is it a safe procedure?

Abstract

Foreskin reconstruction (FR) is a recognised, yet debated, option for patients undergoing single-stage hypospadias repair (HR). We evaluated the incidence of complications after single-stage HR in our institution. This is a retrospective review of all single-stage HR. Patients were classified into group 1 (circumcision) and group 2 foreskin reconstruction (FR). Urethroplasty and foreskin complications were recorded. Statistics used are as follows: Mann-Whitney test to compare age at operation and length of follow-up (FU); Chi-Square test to analyse the incidence of urethral complications and need for reoperation; Log rank test to compare the survival curves; p statistically significant < 0.05. Data are presented as median (range). 304 patients were identified, operated between January 2010 and December 2016, and 20 were excluded: 6 already circumcised at the time of the surgery, 3 with megameatus intact prepuce, 11 lost at FU. 284 patients were included: 161 circumcised and 123 FR. Median age at the operation was 17months (8-179) (group 1) and 17months (8-148) (group 2) (p = 0.71). Length of FU was 19months (8-91) (group 1) and 17months (4-87) (group 2) (p = 0.45). The survival curve was homogeneous (p = 0.28). Urethroplasty complications occurred in 32/161 (20%) (group 1) and in 21/123 (17%) (group 2) (p = 0.55). Foreskin complications occurred in 18/123 (15%). A second operation was required in 33 boys in each group, (20% group 1 and 27% group 2) (p = 0.21). FR does not increase the complication rate or the need for a reoperation after single-stage HR. Parents should be offered the option between the two procedures according to their personal preference.
