Impact of Sleep Position on Stone Clearance after Shock Wave Lithotripsy in Renal Calculi

Abstract

Objectives: We evaluated the impact of sleep position on the effectiveness of shock wave lithotripsy (SWL) in renal calculi. Patients and Methods: 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. Results: 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). Conclusions: 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.

Is physical therapy effective following extracorporeal shockwave lithotripsy and retrograde intrarenal surgery: a meta-analysis and systematic review

“…Thus, self-help position therapy has been performed to improve SFR after lithotripsy [22,23]. Interestingly, physical activities like roller coaster and intercourse have been proved to promote renal stones expulsion, indicating a potential modality to get a higher SFR [21,[24][25][26][27][28]. Later, physical therapies including percussion and inversion were tried in clinical practice [29].…”
