Abstract

Introduction: Acquired megalourethra (AMU) after repair of proximal hypospadias can be a serious complication. An observational retrospective study of its incidence among different types of repair was performed. Materials and methods: Clinical charts of patients operated on for proximal hypospadias were reviewed. Inclusion criteria: all primary hypospadias operated in 1991-2004, with the meatus positioned in proximal penile, scrotal or perineal position. Results: Of 770 hypospadias cases treated, 130 (16%) were proximal. Seventy-two patients (55%) were treated using preputial flaps: 36 with a tubularized preputial island flap (TIF) and 36 an onlay island flap (OIF). Fifty-eight patients (45%) underwent staged repairs: Belt-Fuquà (BF) in 18 and Bracka procedure in 40 cases. After a mean follow up of 16 years (range 6-19) the overall incidence of complications for each technique was: TIF 36%; OIF 33%; BF 25%; two-stage Bracka 7.5%. The most common complication encountered was neo-urethral fistula. AMU occurred in only 5 cases, none with associated distal urethral stenosis, all in the TIF and OIF groups, and all successfully treated by reduction re-do urethroplasty. Conclusion: A very small number of the patients operated using preputial island flaps techniques developed AMU. None of the staged repairs developed AMU, and this is the preferred choice in proximal hypospadias when the urethral plate requires division and/or substitution. All cases of AMU resolved after urethral tapering.
