Abstract：
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.
摘要：
膀胱结石通常发生在膀胱排空不良或膀胱内异物残留的患者中。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。虽然存在许多治疗膀胱结石的技术，包括内窥镜和开放手术入路，我们的新技术可能有助于有效治疗异常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，其大小在1.3cm至6.8cm之间，并通过我们的新技术成功治疗。通过使用耻骨上导管套管针和鞘管来实现对膀胱的经皮进入，以利用双作用碎石仪。通过天然尿道，在刚性膀胱镜的直接可视化下进行鞘层插入和碎石。这种技术很容易学习，并且可以安全地用于其他方法可能会带来更高发病率风险的患者。
