ABSTRACT

OBJECTIVE:

In narrow anterior urethral strictures, the combined buccal mucosa graft (BMG) with pedicled penile skin flap (PSF) represents a well-known effective alternative to staged urethroplasty. We hypothesized that if the native urethral plate and adjacent corpus spongiosum were preserved, a narrower flap would be needed, and reinforced ventral stability could be achieved without compromising the surgical outcome.

METHODS:

Twelve patients with narrow penile urethral strictures underwent single-stage augmentation urethroplasty using a combined technique. A BMG was quilted to the corpora cavernosa in a dorsal onlay approach, and a longitudinal ventral PSF was transposed ventrally and sutured to the scarred native urethral mucosa on one side and to the BMG on the other side to form a neourethra of triangular form. The preserved corpus spongiosum was wrapped and fixed around the flap ventrally.

RESULTS:

The median age was 47 years (IQR 35-59), and the median stricture length was 5 cm (IQR 3, 8-7). The median surgical time was 205 min (IQR 172-236). The overall success rate (SR) was 91.7% without sacculation or diverticula formation after a median follow-up period of 38 months (IQR 33-40). Three transient fistulas healed through prolonged urinary diversion. Five patients (41.7%) reported postvoid dribbling following urethroplasty.

CONCLUSION:

Preservation of the native urethral plate is a valuable adjunct to the combination of graft and flap for single-stage augmentation urethroplasty for narrow urethral strictures, with satisfactory mid-term success and an acceptable complication rate.
