In cases of tight bulbar stricture the dorsal plus ventral buccal mucosa graft provides adequate urethral augmentation by preserving the urethral plate and avoiding postoperative sexual complications.

AbstractA 22-year-old man reported cracking sound and acute pain during sexual intercourse followed by rapid penile detumescence and ecchymosis. He experienced more pain because he could not urinate and had a palpably full bladder. Moreover, his urethra was bleeding. Physical examination revealed swollen, ecchymotic and deviated penis and penis ultrasonography showed an injury of the tunica albuginea and Buck's fascia with an expanding hematoma. Suprapubic catheter was positioned. Surgical exploration revealed a tear of tunica albuginea of both corpora cavernosa and complete urethral dissection. End-to-end urethral anastomosis and suture of corpora cavernosa lesion were performed. Vescical catheter was mantained for 6 days and suprapubic catheter for 3 months to allow a complete urethral healing. A pseudodiverticulum was found at anastomosis level on the urethrocistography 1 month after surgery. It disappeared by allowing micturition via the suprapubic catheter. The patient presented regular urinary flow and physiological erections 30 days later. In our experience, prompt surgical repair preserved erectile function and keeping the suprapubic catheter protected the urethra; this was the correct management for repairing the urethral lesion.

We report the procedure in order to obtain and use an MB homologous cell culture. Using autologous material reduced the surgical time and wiped out the risk of rejection; on the other hand, the tissue was so thin and with no adequate scaffold that the healing retraction of the graft was increased, thus compromising the urethral reconstruction. Preliminary results confirm that bio- engineering applied to urethral surgery is far from obtaining adequate tissue with reference to extension, thickness and biological features.
