An 82-year-old man presented with lower abdominal pain and general malaise. Noncontrast computed tomography revealed a remarkably enlarged prostate and a full bladder with a giant stone 80 mm in diameter causing bilateral hydroureteronephrosis. Laboratory data demonstrated systemic inflammation and renal dysfunction with hyperkalemia. Acute postrenal dysfunction caused by urinary retention was diagnosed. A urethral catheter was inserted and emergent dialysis was initiated. After renal function recovered, we performed lithotripsy for the urinary bladder calculi. To achieve stone free status with a single-stage procedure, we performed simultaneous percutaneous suprapubic and transurethral cystolithotripsy. The procedure was successfully performed without significant complications.
The patient was discharged 9 days after surgery, although clean intermittent catheterization was required.
Giant bladder calculi are often treated with cystolithotomy because transurethral cystolithotripsy requires time to remove all fragments. In this case, we achieved stone free status in acceptable operative time by performing simultaneous percutaneous suprapubic and transurethral cystolithotripsy. In conclusion, the endourological management is an effective treatment choice, even in a case with a giant bladder calculus.
