[Bladder contracture following intravesical BCG immunotherapy treated by hydrodistention: a case report].

A 35-year-old man had undergone retroperitoneoscopic radical nephrouretectomy in May 2002 (pTisNxM0). He later developed carcinoma in situ (CIS) of the bladder, and underwent intravesical instillation of 80 mg of Bacillus-Calmette-Guerin (BCG) once a week for 6 weeks in January 2004. After the treatment, irritative symptoms (frequency and dysuria) developed, and he was diagnosed with bladder contracture.

A 76-year-old male was admitted with massive gross hematuria from an ilial conduit.
