Mechanical rotational lithotripsy of urinary bladder stones, up to 20 mm in diameter, was performed in 6 male patients with the Rotolith lithotriptor. The lithotriptor was introduced through a 10 F (OD 3.3 mm) suprapubically inserted sheath, and the procedure was performed under intermittent fluoroscopy and inspection through a transurethral cystoscope. In 3 patients, the bladder stones were fragmented to pieces small enough to be evacuated through the cystoscope. The instrument, which is designed for lithotripsy of gallbladder stones, was less efficient for fragmentation of urinary bladder calculi, primarily due to the large volume of the human urinary bladder, and possibly because of the higher gravity of bladder stones. There was no substantial damage to the mucosa of the urinary bladder.
使用Rotolith碎石机对6例男性患者直径达20毫米的膀胱结石进行了机械旋转碎石术。通过耻骨上插入的10F（外径3.3毫米）鞘管插入碎石机，该操作在间歇性荧光透视及经尿道膀胱镜检查下进行。3例患者的膀胱结石被碎成足够小的碎片，可通过膀胱镜排出。该仪器是为胆囊结石碎石设计的，对膀胱结石碎石的效率较低，主要是因为人类膀胱容积较大，也可能是由于膀胱结石比重较高。膀胱黏膜未受到实质性损伤。
