UROLITHIASIS

This study tests a new device that combines a camera and suction in one tool for kidney stone removal surgery. About 75 adults with kidney stones between 0.5 and 2.0 cm will undergo the procedure to see if the device safely clears stones and reduces leftover fragments. The goal i…

This trial tests whether a vacuum-assisted ureteral access sheath (ClearPetra) removes kidney stones more completely than a standard rigid sheath (Navigator) during flexible ureteroscopy. About 156 adults with stones 1-3 cm will be randomly assigned to one sheath. The main goal i…

This study compares a new tool called the CVAC system, used with a special scope, to standard treatments for removing kidney stones. About 1,000 adults who need stone removal will be randomly assigned to either the new method or usual care. The main goal is to see if the new appr…

This study compares a new surgical technique, antegrade flexible ureteroscopy-assisted PCNL, to standard PCNL for removing large, branching kidney stones (staghorn calculi). The goal is to see if the new method removes more stone fragments and causes fewer complications. The tria…

This study tests three common pain relievers (ibuprofen, paracetamol, and tenoxicam) against a placebo to see which works best during shock wave treatment for kidney stones. About 160 adults will rate their pain at several points during the procedure. The goal is to find the safe…

This study compares custom-length ureteral stents (based on each person's imaging) to standard one-size-fits-all stents in 128 adults having kidney stone surgery. The goal is to see if the custom stents reduce pain, urinary issues, and other symptoms. Participants will fill out a…

This study looks at whether a retrolaminar block—a numbing injection near the spine—can reduce pain and improve comfort for people undergoing shock wave treatment for kidney stones. About 90 adults will be divided into three groups: one receiving the block, one receiving standard…

This observational study tests a new ultrasound-based measure called the Pelvic Floor Fatigue Index (PFFI), which gauges how quickly pelvic floor muscles tire. Researchers will measure PFFI in 75 adults before they undergo ureteroscopy or retrograde intrarenal surgery for kidney …

This study tests whether a scoring tool called a nomogram can accurately predict if a patient will be completely stone-free after a minimally invasive kidney stone surgery called flexible ureterorenoscopy. Researchers will compare the nomogram's predictions with actual surgical o…

This study will follow about 250 adults having a common kidney stone surgery called RIRS. Researchers will collect information before, during, and after surgery to find out which patients are more likely to develop fever or a serious infection called sepsis. The goal is to help d…
