THE EFFECT OF SUTURING TECHNIQUE AND MATERIAL ON COMPLICATION RATE FOLLOWING HYPOSPADIAS REPAIR

Ninety-seven children with distal hypospadias were treated surgically using perimeatal-based flap urethroplasty (Mathieu procedure) in a two and a half years period. A review of the medical records revealed two distinct groups of patients according to the suturing type and suture material. In the first group of 36 patients (group I), neourethra was constructed using 6/0 polyglactine (Vicryl(R)) in a single layer, ful l-thickness, uninterrupted fashion. Skin flaps were approximated using interrupted simple 5/0 polyglactine (Vicryl(R)) sutures. In the secon d group of 61 patients (group II), 7/0 polydioxanone (PDS(R)) was used in the urethral anastomosis performed in a subcuticular, uninterrupte d fashion. The skin flaps were closed using interrupted simple 5/0 rap idly absorbable polyglactine (Rapid Vicryl(R)) sutures. Patients were followed-up from 6 to 12 months. Urethral or meatal stenosis was not o bserved in any patient. There was no infectious complication. Urethroc utaneous fistula rate was significantly higher in group I (16.6%) comp ared to group II (4.9%) (p < 0.01). Complication rate following hyposp adias repair can be reduced by the use of a subcutaneous suture techni que utilizing polydioxanone suture material in urethroplasties.
