UROLITHIASIS

This study looks back at the medical records of 3000 people who had kidney stones removed using one of two new devices: the CVAC system, a steerable suction catheter, or a special suction tube called FANS. Researchers want to see how well each device clears stones and how safe th…

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 tests a device that uses focused ultrasound to gently push kidney stones, helping them pass or relieving pain. Researchers are enrolling 172 people with kidney stones, including those waiting for treatment or recently treated. The goal is to see if the ultrasound can m…

This study compares two drugs—methocarbamol and oxybutynin—to see which works better for pain and discomfort caused by a ureteral stent placed after kidney stone surgery. About 126 adults aged 18 to 80 who have the surgery will take one of the study drugs along with standard pain…

This study looks at whether removing a ureteral stent 3 days after kidney stone surgery is as safe and less bothersome than the usual 7 days. About 172 adults having simple stone treatment will be randomly assigned to either 3 or 7 days of stent placement. The goal is to see if a…

This study compares a simple sterile water injection into the skin with intravenous morphine for relieving severe kidney stone pain. 150 adults with confirmed stones and high pain levels will receive either one or four water injections or morphine. Pain is measured over 90 minute…

This study looks at whether a measurement called the stone heterogeneity index (SHI), taken from a CT scan, can predict how well shock wave lithotripsy (SWL) breaks up upper urinary tract stones in children aged 1 to 18. Researchers will follow 286 children for three months after…

This study is looking at 150 adults having a specific type of kidney stone surgery called FANS-RIRS. Researchers want to see if the results of a routine urine culture, taken before surgery, can predict whether a patient will develop a fever after the operation. The goal is to hel…

This study from Mayo Clinic looks at whether certain gene variants make people more likely to form calcium oxalate kidney stones. Researchers will compare 2,900 adults with and without a history of kidney stones, analyzing blood samples and lifestyle factors. The goal is to bette…
