Objective:
Over previous years, urethral stricture has constantly created a great problem in efforts to find a permanent cure for it. We describe a technique of anterior urethroplasty using tunica albuginea of corpora cavernosa.
Methods:
After a midline penoscrotal incision, the bulbar or penile urethra along with corpus spongiosum was dissected from the corpora cavernosa. Urethra was then rotated dorsally and the stricture was opened along its whole length. The walls of the slit urethra, along with the tunica albuginea of the corpus spongiosum, were sutured to the tunica albuginea of the corpora cavernosa at the 5 and 7 o'clock position after passing an all silicon catheter. We performed this technique on 79 male patients, having anterior urethral stricture, ranging 18-60 years of age (mean, 46 years). The etiology of stricture was trauma in 54, instrumentation in 12, infection in 10 and unknown in three. Follow ups were done at 4, 12 and 24 months by assessing patients' satisfaction rate along with a pre- and postoperative urethrogram, labeled as "good", "fair" and "poor".
Results:
Good and fair results were considered as successful. The overall success rate was 94.9%. The success rate remained same at 4 months (64 + 11) and decreased to 93.7% (63 + 11) at 12 months and 89.9% (61 + 10) at 24 months.
Conclusion:
These observations show that anterior urethroplasty using tunica albuginea of corpora cavernosa have produced satisfactory results and are comparable with any other technique of urethroplasty. Thus, we strongly recommend the use of tunica albuginea of corpora cavernosa for anterior urethroplasty, which is histologically similar and anatomically located near the stricture.
