KIDNEY STONES

This study compares two procedures for removing 1-2 cm kidney stones from the lower part of the kidney. One method uses a thin tube with a camera through the urinary tract, while the other makes a small incision in the back. The goal is to see if the less invasive approach works …

This study looked at two different approaches to prevent kidney stones in adults who have had at least two stones in the past five years. One approach used diet and medication based on each person's test results, while the other used a standard one-size-fits-all plan. The goal wa…

This study tested whether giving tranexamic acid, a drug that helps blood clot, through a vein and in surgical fluid can reduce bleeding during kidney stone removal. 90 adults with large kidney stones were randomly assigned to receive the drug or a placebo. The goal was to see if…

This study tested a robot-assisted system called MONARCH to remove kidney stones through a small incision in the back. Fifteen adults with stones larger than 1 cm took part. The goal was to see if the robot could safely complete the procedure and clear the stones. Results showed …

This study compared two ways to remove kidney stones that are 2-3 cm in size. One method uses a laser and a special suction tube through a scope in the urinary tract. The other is a mini-surgery that makes a small cut in the back. Researchers looked at how well each method cleare…

This study tested whether giving a diuretic (furosemide) during flexible ureteroscopy for medium-sized kidney stones (up to 30 mm) reduces leftover stone fragments. 2000 adults were randomly assigned to receive furosemide or standard care. Stone-free status was checked with a CT …

This study tested an experimental drug called LLX-424 in 51 adults who have had kidney stones before. The drug works by blocking an enzyme that makes oxalate, a key ingredient in most kidney stones. Participants took the drug or a placebo daily for 8 weeks to see if it safely low…

This study tests whether new software for ultrasound machines can better detect and measure kidney stones compared to standard methods. Researchers will scan 370 adults with known calcium-based kidney stones and compare the results to CT scans and surgical findings. The goal is t…

This study tested a new type of ureteral access sheath with a flexible tip and built-in suction during kidney stone surgery. Fifty adults with kidney stones 10 mm or larger were randomly assigned to receive either the new suction sheath or a standard sheath. The main goal was to …

This study tested whether briefly stopping a patient's breathing during kidney stone laser surgery could make stone removal more efficient by reducing kidney movement. 150 adults with kidney stones were randomly assigned to normal breathing, low-volume breathing, or a short breat…

This study tested three different fluids used during shock wave treatment for kidney stones: plain water, normal saline, and saltier water. The goal was to see which fluid breaks stones best with the least pain and skin problems. 294 adults with kidney stones took part.

This study compared two surgical techniques for removing large kidney stones in children aged 6 to 18. The traditional method leaves a temporary drainage tube in the kidney, while the newer 'tubeless' method skips that tube. Researchers wanted to see if the tubeless approach redu…

This study tested an augmented reality tool that shows surgical trainees where an expert surgeon looks during kidney stone surgery. Ten urology residents used the device on kidney models (phantoms). The goal was to see if this eye-gaze guidance helps trainees learn to explore the…

This study tested an augmented reality (AR) tool that tracks where a surgeon looks during kidney stone surgery. The goal was to help trainee surgeons learn to find all stone fragments, which could reduce repeat surgeries. Eight urology residents participated in a simulated settin…

This completed study looked at 108 adults having surgery for kidney stones. It compared a balloon-tipped catheter to a standard small tube to see which one better prevents stone fragments from moving into the ureter. The goal is to help surgeons choose the best tool for the job.

This study looked at 70 adults having kidney stone surgery to see if the amount of air given by the breathing machine (tidal volume) affects how the surgery goes. Researchers compared low versus standard tidal volume settings to see if they changed surgery time, stone removal rat…
