[Ventral urethroplasty for postoperative urethral stricture in patients with hypospadias]

To investigate the effect of ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias.

From August 2000 to December 2005, 20 patients with anastomotic stricture after hypospadias repair were treated with ventral urethroplasty. The age ranged from 2 to 27 years with an average of 6.4 years. All patients showed dysuria after operation. Main clinical manifestation included dysuria and acraturesis. Interruption of urinary stream occurred in 17 cases; of them, 3 cases had urinary stasis and 4 cases had frequent micturition, urgent micturition and pain in urination. Urethrography and cystourethrography showed 0. 5-1. 0 cm stricture with proximal dilation of urethra in 16 cases and obvious diverticularization in 9 cases. Urine routine examination showed that white blood cell was ++ to ++++ in 16 cases and pus cell was +/+ to ++ in 13 cases.

Twenty cases were followed up 2 months to 4 years (mean 2.3 years). All the cases achieved good results in urination with normosthenuria and normal force of urinary stream. No recurrent stricture, urethrocutaneous fistula, or penile curvature occurred. The cosmesis was satisfactory, and the results of urine routine examination was normal.

Ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias is a simple and effective procedure.
