  • LONGITUDINAL PREPUTIAL PEDICLED FLAP URETHROPLASTY FOR CHORDEE OF Donnahoo TYPE IV

    Objective To investigate the effectiveness of longitudinal preputial pedicled flap urethroplasty for chordee of Donnahoo IV type. Methods Between June 1994 and October 2011, 30 patients with chordee (Donnahoo type IV) underwent longitudinal preputial pedicled flap urethroplasty. The patients’ age ranged from 2 to 16 years (mean, 5.8 years). The morphology of the balanus-navicular fossa-external urethral orifice ranged normal; the penis length was 2.5-6.8 cm (mean, 4.3 cm); the penis bending angle was 35-70° (mean, 40.1°). Primary and secondary operation was 27 cases and 3 cases, respectively. The size of flap ranged from 1.5 cm × 1.3 cm to 4.0 cm × 2.0 cm. Results After correction, the penis length was 3.0-8.5 cm (mean, 6.6 cm); the penis bending angle was 0-10° (mean, 1.2°). All patients were followed up 6 months to 12 years (mean, 33 months). No recurrence, stabbing pain of the balanus, or foreign body sensation occurred during follow-up. Of them, 4 patients (13.33%) had urinary fistular, they had satisfactory results after the second operation; 2 patients (6.67%) had urethral stricture 1 month after operation, they also had satisfactory results after arethral dilatation. The other patients showed no scattering urinary flow and good direction without complication. Six patients had satisfactory sexual function after puberty without erection disorder, pain, or dyspareunia. Conclusion Longitudinal preputial pedicled flap urethroplasty can achieve maximum utilization of prepuce and aesthetic and functional improvement with less complication, so it is a relatively ideal mean for treating chordee of Donnahoo type IV.

There were 3 males and 6 females with an average age of 34.5 years (range, 8-68 years), and with a mean disease duration of 4 hours (range, 30 minutes to 24 hours). The defect ranged from 1.7 cm×0.5 cm to 15.0 cm×8.0 cm, with the mean depth of 0.5 cm (range, 0.3-0.8 cm). Deep tissue exposure was observed. After routine debridement, a vacuum sealing drainage (VSD) was equipped to suck and irrigate for 1 day, then wound was repaired. The superomedial edge of defect was trimmed, then a GBL shape mainly with square and rectangular was designed. According to defect size, a double pedicled flap was designed at the lateroinferior edge of defect, which size ranged from 1.7 cm×1.5 cm to 18.0 cm×15.0 cm. The donor site was sutured directly. VSD was used for 3 days after operation. ResultsAll flaps survived and wound healed, and donor site incision healed well, with invisible scar. All patients were followed up 6 months to 8 years (mean, 4 years). The wounds were repaired well, and the patients had good facial appearance. No rabies attack was observed during follow-up. ConclusionIt is an ideal repair method to chose double pedicled flap and technique of GBL for primary repair of dog bite wounds. Satisfactory cosmetic appearance can be obtained.
