Oxalate production in calcium oxalate stone formers
This study looks at how the body makes oxalate (a natural substance that can form kidney stones) in people who have had calcium oxalate stones. You will eat a special diet and stop supplements for a short time to help researchers understand stone formation.
Birmingham, AlabamaAges 18–80 - NCT06330246Recruiting
Testing a gut bacteria treatment for calcium oxalate kidney stones
This study tests whether giving a specific gut bacteria can help people with calcium oxalate kidney stones. It looks at whether the bacteria can change how the body processes oxalate, which may reduce stone formation.
Birmingham, AlabamaAges 18–80 - NCT06331546Recruiting
Study of gut oxalate absorption in calcium oxalate kidney stone patients
This study looks at how your gut absorbs oxalate, a natural substance in many foods that can lead to kidney stones. By eating special diets and pausing certain supplements, researchers can measure your oxalate absorption. This may help find better ways to prevent kidney stones.
Birmingham, AlabamaAges 18–80 - NCT01127854Enrolling by invitation
Study genes in people with calcium kidney stones
This pilot study looks at how certain gene changes may contribute to calcium oxalate kidney stones. You may be asked for a blood sample and a questionnaire, whether you have a history of stones or not (as a comparison group).
Jacksonville, FloridaAges 18 years+ - NCT05452291Recruiting
Testing multi-sample biomarkers for recurring kidney stones
This study looks for “biomarkers,” which are measurable signs in samples like urine or blood, to help understand and detect recurring urinary stone disease. It may help future patients by improving how doctors predict stone recurrence or identify stone types.
ShatinAges 18 years+ - NCT06569173Recruiting
Comparing two types of ureteral stents for children with kidney stones
This study compares whether a special anti-reflux stent causes fewer symptoms than a standard DJ stent in children treated for kidney stones. The goal is to find which stent is more comfortable and has fewer side effects.
Hangzhou, ZhejiangAges birth–18 years - NCT07620873Recruiting
Virtual Reality Education Before Kidney Stone Surgery
This study tests whether using virtual reality to learn about your upcoming kidney stone surgery can reduce anxiety and help you feel more prepared. You'll use a VR headset before your procedure to see what to expect.

Registry of Mini-Invasive Stone Surgery (MIUS)
This registry collects information on people being treated for kidney stones (urolithiasis) to help doctors learn which treatments work best. It includes patients of any age who have a medical reason for treatment and who allow their records to be used.
IstanbulAges Any age - NCT07859436Recruiting
Audio consent for kidney stone surgery
This study tests whether adding a voice recording (human or AI) to the written consent form helps patients understand their upcoming kidney stone surgery better before they agree to it.
Aydin, AydınAges 18 years+ - NCT07868874Enrolling by invitation
Two versus four weeks of stent before ureteroscopy
This study compares leaving a ureteral stent in place for two weeks versus four weeks before a second procedure to remove kidney stones. The goal is to see which waiting time makes the second procedure easier and safer.
Islamabad, FedralAges 18–65 - NCT07786844RecruitingPhase 1/Phase 2
Norepinephrine irrigation fluid for kidney stone surgery
This study tests whether adding norepinephrine (a medicine that helps narrow blood vessels) to the fluid used during kidney stone surgery can reduce bleeding. It is for people with stones in the kidney or upper ureter who are having a specific minimally invasive surgery.
Nanjing, JiangsuAges 18–75 - NCT07767773Recruiting
Long-term safety of two kidney stone scope methods
This study is checking the long-term safety of two different ways of doing a kidney stone scope procedure (one uses a small tube to guide the scope, the other does not). If you had this procedure for a kidney stone (up to 20 mm) and it's been at least a year, they want to follow up with you to see how you're doing.
CairoAges 18 years+ - NCT07763613Recruiting
Study of pelvic floor strength after kidney stone surgery
This study measures a new score called the pelvic floor fatigue index, which looks at how tired the pelvic floor muscles get, in people who have a ureteral stent placed after kidney stone surgery. The goal is to see if this score can help predict or prevent bladder problems that stents can cause.
Trabzon, TrabzonAges 18–65 - NCT07742358Recruiting
Comparing ureteral stent designs in children with kidney stones
This trial compares two types of ureteral stents (small tubes that help urine drain from the kidney to the bladder) in children having surgery for kidney stones. The goal is to see which type causes fewer symptoms like pain or discomfort.
Toronto, OntarioAges 8–18 - NCT07685587Recruiting
Comparing two types of ureteral access sheaths for kidney stone surgery
This trial compares two methods used during surgery to treat kidney stones. It looks at whether one type of tube (a fan-shaped access sheath) causes less kidney injury after surgery than the standard tube. This could help patients have a safer recovery.
TekirdağAges 18 years+ - NCT07655050Recruiting
Antibiotic wash during kidney stone surgery
This study tests whether washing the urinary tract with antibiotics during kidney stone surgery can help prevent infections. It's for people scheduled for a procedure called RIRS to remove kidney stones.
Çorum, ÇorumAges 18 years+ - NCT07627828Recruiting
ComfiJ versus standard stent for kidney stone recovery
This trial compares two types of temporary drainage tubes (stents) placed in the ureter—the tube that carries urine from kidney to bladder—after surgery to remove kidney or ureteral stones. The study measures which stent causes fewer uncomfortable symptoms during the 2-week recovery period.
Banī Suwayf, Beni Suweif GovernorateAges 18 years+ - NCT07623980Recruiting
Laser Treatments for Childhood Bladder Stones
This trial compares two laser methods to break up bladder stones in children. Both approaches use a thin camera inserted through the urethra (the tube that carries urine), and the study aims to find which method works better and causes fewer complications.
Banī Suwayf, Beni Suweif GovernorateAges Up to 18 years - NCT07617896RecruitingPhase 2
Aminophylline to help remove kidney stones in children
This trial tests whether a medication called aminophylline, placed directly in the bladder during surgery, helps doctors access and remove small stones stuck in the lower ureter (the tube that carries urine from the kidney). It's designed for children whose ureter is difficult to reach during the initial procedure.
Banī Suwayf, Beni Suweif GovernorateAges 2–18 - NCT07614880Recruiting
Two methods for removing bladder stones in children
This study compares two minimally invasive surgical techniques to remove bladder stones in children ages 2–14. Both approaches aim to break up and remove stones with less recovery time than traditional open surgery.

Common questions
- Are there clinical trials for urolithiasis?
- Yes. Clin2 currently lists 35 recruiting urolithiasis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a urolithiasis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a urolithiasis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
