Bladder or urethral calculi in 50 patients were effectively fragmented and removed per-urethrally using an ultrasonic lithotriptor with the probe vibrating at 30,000 implulses/s. In adults, local anaesthesia was employed and the operation performed as an out-patient procedure. The method has the advantages over others discussed in that a small (23 F) sheath is used and that damage to the bladder or urethra by the probe is avoided. Using a newer, modified sheath resembling that for punch prostatectomy, larger stones can be fragmented by engaging the stone in the fenestrum of the sheath.
使用探头以每秒30000次脉冲振动的超声碎石器经尿道有效地破碎并取出了50例患者的膀胱或尿道结石。对于成人，采用局部麻醉，该手术作为门诊手术进行。该方法与所讨论的其他方法相比具有优势，因为使用的鞘管较小（23F），并且避免了探头对膀胱或尿道的损伤。使用一种类似于经尿道前列腺切除术所用的新型改良鞘管，通过将结石卡在鞘管的开窗处，可以破碎更大的结石。
