Passing kidney calculi can be excruciatingly painful for patients, likened to childbirth in intensity. The mechanism of the simple act of passing a stone, however, is not well understood. A recent research article examined a novel approach for optimizing kidney stone clearance—sleep position, a simple noninvasive concept that might improve urinary stone passage.
肾结石患者在排石过程中可能会经历剧痛，其强度可与分娩相媲美。然而，人们对这一简单排石过程的机制尚不完全了解。最近的一篇研究文章探讨了一种优化肾结石清除的新方法——睡眠姿势，这是一种简单的非侵入性理念，可能有助于促进尿路结石排出。
