Chordee without hypospadias: report of 79 Chinese prepubertal patients.

A series of Chinese prepubertal patients with congenital chordee without hypospadias is presented and the clinical data described. From July 1999 to September 2006, 79 boys with congenital chordee without hypospadias were treated in the Department of Pediatric Surgery, West China Hospital of Sichuan University, China. The ages ranged from 21 months to 14 years, with a mean of 76.8 months (6.4 years). The patients were categorized according to structural defect into 4 groups, with the aid of intraoperative artificial erection. Group I included those with skin tethering (28 cases, 35.4%); group II, fascial chordee (22, 27.8%); group III, corporal disproportion (10, 12.7%); and group IV, urethral tethering (19, 24.1%). Chordee-related structural defect was considered the only criterion for classification, and urethral dysgenesis influenced the choice of surgical procedure. The chordee in group I patients was corrected with penile degloving; group II, release of dense fibrous tissue in addition; group III, dorsal-midline-plication-based correction; and group IV, longitudinal-island-flap-urethroplasty-based repair. At a mean follow-up of 14.8 months (range, 2 to 63), all patients had penile straightening except 1 group III patient with residual curvature that was managed upon reoperation. Glans dehiscence occurred in 1 group II patient who underwent a tubularized incised plate urethroplasty. Urethrocutaneous fistula and urethral stricture were found in 2 group IV patients who underwent island flap urethroplasty. With the categorization based on structural defect, chordee without hypospadias may be managed well with minimized complications.
