Bladder calculi commonly develop in patients with poor bladder emptying or those with retained foreign bodies within the bladder, leading to irritative voiding symptoms, hematuria, and an increased likelihood of refractory urinary tract infections. While many techniques exist for the treatment of bladder calculi, including endoscopic and open-surgical approaches, our novel technique may help manage exceptionally large or difficult-to-treat bladder calculi effectively. We present three patients with symptomatic bladder calculi ranging from 1.3 cm to 6.8 cm in size who were successfully treated by using our novel technique. Percutaneous access to the bladder was obtained by using a suprapubic catheter trocar and sheath to enable the utilization of a dual-action lithotriptor. Sheath insertion and lithotripsy were performed under direct visualization with a rigid cystoscope via the native urethra. This technique is easily learned and can be safely employed in patients in whom other methods may pose risks of higher morbidity.
膀胱结石通常在膀胱排空不良的患者或膀胱内有异物残留的患者中形成，导致刺激性排尿症状、血尿以及难治性尿路感染的可能性增加。虽然存在多种治疗膀胱结石的技术，包括内镜和开放手术方法，但我们的新技术可能有助于有效处理特别大或难以治疗的膀胱结石。我们介绍了三名有症状的膀胱结石患者，结石大小从1.3厘米到6.8厘米不等，他们通过使用我们的新技术成功得到治疗。通过耻骨上导尿管套管针和鞘管经皮进入膀胱，以便能够使用双动碎石器。鞘管插入和碎石术在硬性膀胱镜经自然尿道直接可视化下进行。这种技术易于掌握，对于其他方法可能带来较高发病风险的患者可以安全使用。
