We evaluated the impact of sleep position on the effectiveness of shock wave lithotripsy (SWL) in renal calculi.
Patients (n = 120) with a single radiopaque renal stone who were candidates for SWL were enrolled. For studying patients' position during sleep, a novel sleep position recorder was designed. Group 1 (n = 60) consisted of patients who slept preferentially on the ipsilateral side of the stone; group 2 (n = 60) comprised patients who slept preferentially on the contralateral side. Treatment effectiveness was defined as the absence of residual stones >3 mm up to 3 months after SWL.
The mean (range) percent of sleep on the ipsilateral side of the stone was 61.5% (51-78) and on the contralateral side it was 62.4% (51-81) in groups 1 and 2, respectively (p > 0.05). The overall success rate of SWL was 88.3% (77.4-95.2) and 70.0% (56.8-81.2) in groups 1 and 2, respectively (p = 0.01). Stone clearance increased with an increasing percent of total sleep time on the ipsilateral side of the kidney stone (p = 0.045).
The percent of stone-free patients was higher in the group of patients who slept ipsilaterally relative to the kidney stone compared with patients who slept on the contralateral side.
我们评估了睡眠姿势对肾结石冲击波碎石术（SWL）疗效的影响。
纳入120例适合SWL治疗的单颗不透X线肾结石患者。为研究患者睡眠时的姿势，设计了一种新型睡眠姿势记录仪。第1组（n = 60）由优先睡在结石同侧的患者组成；第2组（n = 60）由优先睡在对侧的患者组成。治疗效果定义为SWL术后3个月内无残留结石>3 mm。
第1组和第2组患者睡在结石同侧的平均（范围）睡眠时间百分比分别为61.5%（51 - 78）和睡在对侧的为62.4%（51 - 81）（p>0.05）。第1组和第2组SWL的总体成功率分别为88.3%（77.4 - 95.2）和70.0%（56.8 - 81.2）（p = 0.01）。结石清除率随肾结石同侧总睡眠时间百分比的增加而增加（p = 0.045）。
与睡在对侧的患者相比，睡在肾结石同侧的患者结石清除率更高。
