[Renal Failure Due to a Bladder Stone Associated with a Suprapubic Catheter Left for Ten Years ; A Case Report].

A 43-year-old male was injured by a heavy industrial machine in 1998, and suprapubic catheter was inserted because of pubic fracture and urethral injury. He monthly changed the catheter until 2005, but he stopped going to the hospital. Ten years later, in August 2015, he visited our hospital for tiredness. Computed tomography scan showed a huge bladder stone (6×6×4 cm) with suprapubic catheter and bilateral severe hydronephrosis. The level of serum creatinine was 4.79 mg/dl. Bilateral nephrostomy was performed immediately. After improvement of renal function, we performed cystolithotomy and cystostomy. Bilateral nephrostomy was removed with antegrade pyelography seven days after surgery, and he went home on the fourteenth day. Bladder stones due to long-term catheterization without exchange are very rare. We report the clinical course and findings about this patient.
