PURPOSE: To analyze the effects on voiding and complications of one-stage urethroplasty for urethral stricture.
METHODS: All patients who underwent one-stage urethroplasty for stricture in two health institutions in Enugu, Nigeria, between January 1989 and December 1998, were included. The age of the patient, duration of symptoms and the cause of the stricture were noted. Retrograde urethrogram and, when necessary, micturating cystourethogram was done. Urethroplasty was either by substitution using pedicled penile skin flap or by end-to-end anastomosis. Patients were followed up monthly for 1 year during which the patient's ability to urinate satisfactorily was assessed and any complications were noted. One hundred and forty-four (144) men, aged between 11 and 76 years (mean 36.3 +/- 11.2 years), were studied. These included 121 cases who had rapidly recurring strictures after internal urethrotomy or dilatation and 23 cases of complete stricture. Etiology of the stricture included external trauma (43.8%), postinflammatory (36.1%) and iatrogenic (post-catheterization; 20.1%). Ninety-one (63.2%) strictures were in the anterior urethra, 47 (32.6%) in the posterior urethra and six (4.2%) bulbomembranous. The mean length of the strictures was 3.1 +/- 1.4 cm.
RESULTS: Anastomotic urethroplasty was performed in 98 (68.1%) patients and substitution in 46 (31.9%). Hospital stay was between 12 and 14 days, except in those who developed complications. Normal voiding was achieved in 124 (86.1%) patients. Urethral fistula was encountered in five (3.5%) patients and recurrent stricture in 15 (10.4%). There was no mortality.
CONCLUSIONS: One-stage urethroplasty affords an excellent cost-effective means of reconstruction of the urethra in patients with stricture of various etiologies. In our environment in particular, it avoids the fulminating infection often encountered after the first stage of a two-staged operation.
