New 2-stage buccal mucosal graft urethroplasty.
OBJECTIVE
Previously buccal mucosal grafts used for repairing adult bulbourethral stricture with the 1-stage dorsal technique has provided a satisfactory outcome in our experience. We present the wider use of buccal mucosal grafts for 2-stage urethroplasty.


METHODS
A total of 24 men 25 to 60 years old (median age 45) with a complex bulbar stricture underwent 2-stage urethroplasty using a buccal mucosal graft to repair the perineostomy. The primary etiology of stricture was traumatic in 4 cases, inflammatory in 16 and unknown in 4. The 2 x 6 cm. graft was harvested from the inner cheek and sutured to the left margin of the urethral mucosal plate with running 6-zero polyglactin suture. Patients were discharged from the hospital within 3 days with a 14Fr silicone urethral catheter in place. Radiological studies and urethroscopy were done 1 year after closure.


RESULTS
A final successful outcome with no recurrent stricture was achieved in 23 of 24 men (92.8%) at a median followup of 18 months (range 13 to 32). In 1 case a urethrocutaneous fistula at the initial radiological assessment closed spontaneously after 14 days of catheterization. No urethral diverticula developed. The mean postoperative peak flow rate is 22 ml. per second (range 18 to 25).


CONCLUSIONS
Our new 2-stage buccal mucosal graft urethroplasty may be an excellent technique for complex bulbar urethral stricture disease. Our suggestions may increase usefulness of the 2-stage technique for repairing complex strictures due to the avoidance of classic complications.
