Giant urethral diverticulum: unusual complication following ventral buccal mucosa onlay graft urethroplasty.

During the past 10 years, buccal mucosa grafting for urethroplasty has gained widespread acceptance. In general the reported success rates are 80% and higher. Typical complications are recurrent strictures, fistula, and, especially when the technique of ventral onlay urethroplasty has been used, sacculations that are of little clinical significance in most cases. The development of large diverticula has not been described yet. We report on the case of a 63-year-old man who developed a giant diverticulum of the urethra 1 year after a ventral buccal mucosa onlay graft urethroplasty for recurrent bulbar urethral strictures had been worked out.
