Results Eight, 5, 8, 4 and 3 studies included in meta-analyses for the modified Seoul
National University Renal Stone Complexity Score (S-ReSC), RIRS, Resorlu-Unsal Score …

Kidney stones form when mineral salts crystallize in the urinary tract. While most stones exit
the body in the urine stream, some can block the ureteropelvic junction or ureters, leading to …

Background Kidney stones account for a high proportion of urological emergencies. The
main objective of this paper is to evaluate the predictive ability of five scoring systems for …

To enhance the accuracy of predicting stone-free rates after retrograde intrarenal surgery,
we devised a novel approach to assess the renal infundibulopelvic angle. We conducted a …

Objective: To evaluate the efficacy and safety of a novel tip-flexible suction ureteral access
sheath (NTFS-UAS) combined with flexible ureteroscopic lithotripsy (FURS) for treating …

Purpose This study aims to assess stone-free rates after flexible ureterorenoscopy (fURS)
using the TO HO.(Tallness, Occupied lesion, Hounsfield unit evaluation) scoring system and …

Results: About 100 patients were studied, with 50 in each group. The overall operating time
and lasing time in the T-RIRS group were less than that in the S-RIRS group (P< 0.001). The …

Objective Our primary aim is to perform the external validation of the current scoring systems
in predicting stone-free status (SFS) after retrograde intrarenal surgery (RIRS) for renal …

Objetivo Nuestro objetivo principal es realizar la validación externa de los sistemas de
puntuación actuales para predecir el estado libre de cálculos (ELC) después de la cirugía …
