KIDNEY STONE

This study is testing whether giving two shockwave treatments for kidney stones in the same week is as effective and safe as spacing them three weeks apart. It involves 600 adults with medium-sized kidney stones (8-15 mm). Researchers will compare how quickly people become stone-…

This study is testing whether a commercial lemonade drink or a potassium citrate supplement can change the chemistry of a person's urine to make it less likely for kidney stones to form. It involves 10 adults with a history of kidney stones and specific urine test results. Partic…

This study aimed to test how well a device called RetroPerc® works during surgery to remove large kidney stones. It planned to measure things like surgery time, hospital stay, and whether patients became stone-free. The trial was withdrawn by the sponsor before any patients were …

This study is testing if a specific weight loss program can reduce the body's production of a chemical called oxalate, which is a main component of many kidney stones. It involves obese adults who have previously formed calcium oxalate stones. Participants follow a strict, low-ox…

This study is looking back at medical records to see how well a new kidney stone removal system worked for 3,000 patients. The system uses a small, steerable tube to vacuum out stones during a standard procedure. Researchers want to know if patients were stone-free after surgery …

This study is testing a new surgical technique designed to make kidney stone removal more effective. Doctors are using a special suction tool to hold the stone in place while breaking it up, aiming to shorten the procedure time and improve results. The study will measure how long…

This pilot study is testing whether a daily meditation practice can help patients feel less pain and anxiety before and after surgery to remove kidney stones. Researchers will randomly assign 50 patients (ages 12 and up) to either learn meditation or receive usual care. The goal …

This study aimed to check if a new type of ureteral stent, placed after kidney stone procedures, causes urine to flow backward from the bladder. Researchers planned to use imaging to grade this backflow in adult patients with kidney stones. The trial was withdrawn before any part…

This study aims to understand why people with obesity might be more prone to forming calcium oxalate kidney stones. Researchers are comparing how people with a normal weight and people with obesity process a natural substance called oxalate, which is a key component of these ston…

This study aims to understand why people with obesity have a higher risk of developing kidney stones. Researchers will put 40 healthy adults without a history of stones on a special low-oxalate diet to measure how much oxalate their bodies produce internally. The goal is to gathe…

This study aims to learn how often small kidney stones (4mm or smaller) pass out of the body on their own within 4 to 8 weeks. Researchers will follow 1600 patients to see if factors like pain level, stone location, or blood tests can predict whether a stone will pass without sur…
