Flexible Ureteroscopy and Nephroscopy for Stone Removal in Patients with Multiple Renal Calculi

Abstract

Objective. Renal calculi are a common type of urological calculi and are associated with morbidity. This study was aimed at exploring the effect of flexible ureteroscopy and nephroscopy on stone removal in patients with multiple renal calculi. Method. This randomized controlled trial included a total of 78 cases with multiple renal calculi in our hospital. The patients were randomly divided into the study and control groups and treated with flexible ureteroscopy and percutaneous nephrolithotomy with pneumatic ballistics, respectively. The surgery condition, levels of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), keratocyte growth factor (KGF), renal function indices, and the incidence of complications were analyzed before and after surgery in the two groups. Result. The operation time, the postoperative analgesia pump application time, one-time stone removal rate, the intraoperative blood loss, and hospital stay of the study group were significantly lower than those of the control group. Postsurgery, the levels of PGE2, PGF2α, and KGF in the study group were significantly lower than those in the control group. The serum levels of SCR, BUN, and NGAL in the study group were significantly lower than those in the control group. In addition, the incidence complications in the study group were significantly lower. Conclusion. Flexible ureteroscopy and laser lithotripsy under nephroscopy were equally effective against multiple renal calculi. Flexible ureteroscopy reduced surgical trauma without affecting renal function and had a low incidence of complications.

Risk factor analysis for infection and bleeding after lateral decubitus percutaneous nephrolithotomy

“…Similar to postoperative infection, larger stones and multiple stones make the surgical procedure more challenging, leading to longer surgical durations, and patients with thicker renal cortexes and longer tracts may be more prone to bleeding. [28,29]…”

“…Similar to postoperative infection, larger stones and multiple stones make the surgical procedure more challenging, leading to longer surgical durations, and patients with thicker renal cortexes and longer tracts may be more prone to bleeding. [28,29] Previous studies have found a correlation between multiple tract punctures and postoperative infection and bleeding, as multiple tracts may introduce more infectious agents and increase the risk of bleeding. However, in our study, no significant association was found between multiple tract punctures and postoperative infection, consistent with some previous research.…”
