This study compared the effect of endourological procedures with or without the Amplatz sheath (AS) on cystolithotripsy.
We retrospectively analysed 18 patients who underwent treatment for bladder stone over 30 mm. This study consisted of two groups, namely, patients who underwent cystolithotripsy with an AS (AS group) and those who underwent standard procedure without an AS (SP group). The stone-free rate, total energy used for operation, operation time, days of admission after operation, and complication of both groups were compared.
The number of patients in the AS and SP groups was 10 and 8, respectively. Significant differences were not found between these two groups with regard to age, stone burden, stone volume, number of stones, and history of neurogenic bladder. All patients in both groups achieved a stone-free state. Total energy was significantly increased and operation time was shorter in the AS group. No significant difference was observed in terms of days of admission after operation. Any complications were not increased by the use of AS. Struvite was the most common stone component in both groups.
Use of an AS can shorten the operation time of cystolithotripsy without increasing perioperative complication.
本研究比较了内镜下碎石术联合与不联合 Amplatz 鞘（AS）对膀胱结石碎石的效果。
我们回顾性分析了 18 例接受大于 30mm 膀胱结石治疗的患者。本研究包括两组，即接受 AS 辅助下膀胱碎石术（AS 组）和未使用 AS 进行标准手术的患者（SP 组）。比较两组的结石清除率、手术总能量、手术时间、术后住院天数和并发症。
AS 组和 SP 组患者分别为 10 例和 8 例。两组患者在年龄、结石负荷、结石体积、结石数量和神经源性膀胱病史方面无显著差异。两组患者均达到结石清除状态。AS 组的总能量显著增加，手术时间更短。术后住院天数无显著差异。使用 AS 并未增加任何并发症。两组中最常见的结石成分均为鸟粪石。
使用 AS 可缩短膀胱碎石术的手术时间，且不增加围手术期并发症。
