KIDNEY STONE

This study compares two versions of a minimally invasive kidney stone removal surgery. Researchers want to see if using a vacuum-assisted tube works better than a standard tube for removing medium-sized stones. About 90 patients will have their surgery and recovery tracked to mea…

This study is testing a new surgical tool called VISOR for people with kidney or ureter stones. The goal is to see if it can safely break up and remove stones in one procedure, aiming to leave very few fragments behind. Participants will have surgery with the device and then get …

This study is testing if giving a diuretic drug (Furosemide) with IV fluids right after laser kidney stone surgery helps flush out tiny leftover stone fragments. The goal is to see if this 'forced diuresis' reduces the chance of these fragments sticking around and forming new sto…

This study is testing a new medical device called ClearPetra™, which uses suction to remove kidney stones during surgery. Researchers want to see if it helps clear stones more completely and reduces infections after surgery compared to the standard tools. The trial will involve 1…

This study is testing whether a new flexible suction device can improve outcomes during a common kidney stone removal procedure. Researchers will compare the new device against standard equipment in 33 adult patients with stones in the lower part of the kidney. The main goal is t…

This study is testing whether following a healthy DASH-style diet for one week can lower the risk of forming new kidney stones. Researchers will provide all meals to 48 adults who have had kidney stones before. They will compare urine test results from people on the healthy diet …

This small, early-stage study is testing if giving an anti-inflammatory drug (Ketorolac) *before* placing a ureteral stent can reduce the pain and urinary symptoms many patients experience afterward. The study will enroll 36 adults getting a stent for kidney stones. Researchers w…

This study is testing whether patients recover better without a temporary internal tube (stent) after a common kidney stone procedure. Researchers will compare pain levels, daily life impact, and healthcare visits over 30 days between patients who get a stent and those who do not…

This study aims to understand the connection between kidney stones, insulin resistance, and inflammation. Researchers will compare 20 people who have had calcium kidney stones with 20 healthy people. They will measure body fat, take blood and urine samples, and analyze them to se…

This study aims to understand how a supplement called potassium citrate affects two natural body chemicals, oxalate and citrate, which are linked to kidney stone formation. Researchers will give the supplement to 24 people—half with a history of kidney stones and half without—and…

This study aims to learn how two common food compounds, oxalate and citrate, influence a person's chance of forming kidney stones. Researchers will give 50 participants (25 with a history of stones and 25 without) a single dose of oxalate and then measure changes in their urine a…

This study aims to understand how the body's natural breakdown of vitamin C contributes to a substance in urine that can form kidney stones. Researchers will feed participants a special diet and give them a safe, traceable form of vitamin C to measure its effects. The goal is to …

This study aims to understand the body chemistry of people who get kidney stones. Researchers will compare leftover blood and urine samples from 20 people with kidney stones to samples from people without stones. By looking for differences in specific chemicals, they hope to find…
