Percutaneous Suprapubic Ultrasonic Lithotripsy of Bladder Stones / 대한비뇨기과학회지

ABSTRACT

Seven patients with bladder stones underwent percutaneous ultrasonic lithotripsy, suprapubically The stones ranged from 1.7 to 4.0 cm (mean 2.3 cm) in diameter. Mean treatment time was 49 minutes with a range of 10 to 120 minutes. The stone free rate was 100%. Among 7 patients 3 had unclear causes for bladder stone formation but 4 associated with etiologic disorders; BPH in 1, neurogenic bladder after spinal injury in 1, anterior urethral stricture in 1 and foreign body (paraffin) in bladder in 1. Under the intravenous narcotics and local anesthesia, all 7 patients well tolerated to pain but 6 complained a minimal voiding sense during the procedure. There was no complication such as bladder injury, bleeding or severe hematuria. Therefore, percutaneous suprapubic ultrasonic lithotripsy is considered to be a simple, safe and efficient outpatient procedure for the treatment of bladder stone.
