COMPARATIVE STUDY BETWEEN DORSAL INLAY BUCCAL MUCOSAL GRAFT(BMG) URETHROPLASTY TO DORSOLATERAL BMG IN THE MANAGEMENT OF LONG ANTERIOR URETHRAL STRICTURE

Abstract

OBJECTIVES: Urethroplasty can be done by placing buccal mucosal graft (BMG) ventrally, dorsally or dorsolaterally.
The objectives of our study were to compare the success rate between dosal bmg and dorsolateral BMG in the
management of urethral stricture.
MATERIALS AND METHODS: This is a prospective study of total 88 patients with stricture of anterior urethra over a 2 year period. Out of 88
patients 30 were treated with dorsolateral onlay BMG urethroplasty and 58 patients were treated with dorsal BMG urethroplasty.
RESULTS: The etiology of stricture was lichen sclerosus in 39.8%. Panurethral strictures were more common. The mean length of stricture was
9.31 ± 2.46 cm. 20% had minor complications at surgical site. During the followup of months success rate was 93.94% in bulbar strictures,
97.83% in penile strictures, and 84.21% in panurethral strictures.
CONCLUSION: When compared to dosral onlay BMG urethroplasty, Dorsolateral onlay BMG urethroplasty avoids the extensive
circumferential mobilization of the urethra and preserves vascular, muscular and neurogenic support. The morbidity and complications are low
and outcomes are excellent. Dorsal inlay (Asopa Technique) is easy to carry out, provide shorter operative time and less blood loss. Urethal
dissection and rotation is not required, so blood supply is not affected.
