Study of Negative Pressure Suction Effects on Fluid Absorption and Infection Risk During Flexible Ureteroscopic Kidney Stone Surgery

What this Trial Is About

This research aims to learn about the effects of using negative pressure suction during retrograde intrarenal surgery RIRS in adults aged 18 and older with kidney stones. It focuses on whether this suction method affects how much irrigation fluid is absorbed during surgery and if it lowers the risk of postoperative infections like fever, systemic inflammatory response syndrome SIRS, and urosepsis. The study compares patients who have surgery with a negative pressure suction sheath to those using a standard sheath without suction. Participants will undergo their scheduled kidney stone surgery as part of their usual care. The study groups include those receiving surgery with a negative pressure suction sheath and those with a standard ureteral access sheath. During surgery, researchers will monitor details such as surgery duration and the volume of irrigation fluid absorbed using a monitoring device. Throughout the study, researchers will collect clinical data including preoperative tests CT scans, ultrasounds, urine tests, intraoperative data, and postoperative recovery information like body temperature, pain levels, hospital stay length, and any infections. The main outcome measured is the volume of irrigation fluid absorbed during surgery, along with secondary outcomes like incidence of postoperative fever or infection within 7 days, length of hospital stay, and stone-free status one month after surgery.
