ABSTRACT：Flexible ureteroscopic lithotripsy （FURL） is one of the major minimally invasive endoscopic techniques in the management of upper urinary tract stones，but it has problems of low stone-free rate，high intraoperative intra-pelvic pressure，and high risk of postoperative infection.Since the negative pressure suction technique has been applied to FURL，it can actively suck out the stone powder and perfusion fluid during operation，thus significantly improving the immediate intraoperative stone removal rate，effectively reducing the intrarenal pelvic pressure，increasing the clarity of the operation field，and significantly improving the efficiency and safety of FURL.With the continuous progress of technology，the negative pressure suction technique has evolved from the initial simple negative pressure suction to the intelligent pressure control system integrating ‘perfusion-measurement-negative pressure.Although this technique is now widely used in FURL，there is still optimizing space in terms of device design and operational application.This article will focus on the clinical application，technical progress and operational experience of the negative pressure suction technique in the light of domestic and international literature.

摘要：經(jīng)尿道輸尿管軟鏡碎石術(shù)（FURL）是臨床處理上尿路結(jié)石的主要微創(chuàng)內(nèi)鏡手術(shù)之一，但仍存在結(jié)石清除率低、術(shù)中腎盂內(nèi)壓高、術(shù)后感染風(fēng)險高等臨床痛點。（剩余11586字）
