Artificial urinary sphincter implantation after pubectomy for bone tumor.

We report 2 cases of unilateral and bilateral excision of pubic bone tumors (chondrosarcoma and giant cell tumor). Postoperative stress incontinence was corrected by implantation of an artificial sphincter (AMS800) following which both patients were continent. The etiology of the incontinence was lack of bladder and urethral support, which was not correctable by bladder neck suspension procedures.
