- NCT07306819Recruiting
Two kidney stone removal methods compared
This study compares two ways to remove kidney stones: mini-PCNL (a small incision in your back) versus flexible ureteroscopy with a suction sheath (a tube through the urinary tract). It aims to find which method works better and is safer for stones of this size.

Genetic testing for inherited kidney stone causes
This study uses genetic testing to look for inherited (“monogenic”) reasons some people get kidney stones. It may help explain the cause of stones and calcium-related problems, which can guide future care for you or your family.
Rochester, MinnesotaAges Any age - NCT06815120Recruiting
New stent study for kidney stone and cancer patients
This trial tests a new type of ureteric stent (a tube that helps drain urine from the kidney) against the standard stent. It is open to patients who have had a stent before and need a new one because of kidney stones or cancer pressing on the ureter.
Southampton, EnglandAges 18–99 - NCT05866081Recruiting
Testing whether to skip a stent after kidney stone procedures

Tucson, ArizonaAges 18 years+ - NCT07421843Enrolling by invitation
Shorter vs longer wait between shockwave treatments for kidney stones
This study compares two different waiting times between shockwave treatments for kidney stones that are 8 to 15 mm. They want to see if a longer or shorter gap between sessions works better to break up the stone.
HelsingborgAges 18 years+ - NCT06938113Enrolling by invitation
Ureteroscopy with negative pressure sheath for kidney stones
This trial tests a procedure called ureteroscopy combined with a special sheath that uses negative pressure to remove kidney stones. It may help people with medium-sized stones get a more complete removal in a single treatment.
Beijing, Beijing MunicipalityAges 18–75 - NCT06394908Enrolling by invitation
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 - NCT07225764RecruitingPhase 4
Kidney stone prevention trial for calcium oxalate stone formers
This trial tests a new approach to prevent calcium oxalate kidney stones from coming back. It may help people who have had a procedure to remove stones and have a specific stone type.
New York, New YorkAges 18 years+ - NCT07076589Recruiting
New tool vs. standard tool for kidney stone surgery
This trial tests a new flexible suction tube for kidney stone removal versus the standard tube. It aims to see if the new tool works better and is safer for patients with small kidney stones.
CairoAges 14 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.
KeelungAges 18 years+ - NCT06003348RecruitingPhase 4
Can a supplement help prevent calcium phosphate kidney stones?
This study tests a supplement called hydroxycitrate to see if it can help people who form calcium phosphate kidney stones. It may offer a new way to prevent stones from forming.
Dallas, TexasAges 21–99 - NCT06684756Recruiting
Comparing two types of ureteral access sheaths for kidney stone surgery
This trial compares a vacuum-assisted ureteral access sheath to a standard one during kidney stone surgery (retrograde intrarenal surgery). The goal is to see which might work better and be safer for patients.
Tekirdağ, TurkeyAges 18–85 - NCT07297953Recruiting
Access sheaths and stents study for kidney stone treatment
This study looks at the use of a ureteral access sheath (a tube that helps the surgeon reach the kidney) in people who already have a ureteral stent (a small tube placed in the ureter) and are having a stone removal procedure called ureteroscopy. It aims to find out if using this sheath is helpful for treating stones in the kidney or ureter.
Ann Arbor, MichiganAges 18 years+ - NCT07562282Recruiting
Medication combinations for kidney stone stent discomfort
This trial tests two different doses of medications (tamsulosin and tadalafil) to help with pain and discomfort from a plastic tube (called a DJ stent) placed in your kidney after stone removal surgery. The goal is to find which dose combination works best and is safest.
Cairo, AbbasiaAges 18–71 - NCT07176026Enrolling by invitation
Follow-up for small kidney stones (≤4 mm)
This trial is for people who have a small kidney stone (less than 4 mm) in the ureter, seen on a CT scan, and don't need urgent treatment. It studies how best to follow up on these stones.
HelsingborgAges 18 years+ - NCT06898216Recruiting
Comparing two tools for small kidney stones
This trial tests if a new steerable scope works better than a standard scope for removing small kidney stones (<2 cm) from the lower part of the kidney. It aims to find a safer and more effective way to treat these stones.
Guangzhou, GuangdongAges 18–75 - NCT06510101Enrolling by invitation
Salvaging donor kidneys with stones
This study tests a way to remove kidney stones from donated kidneys before transplant, using a flexible scope to break up the stones. It might help people who receive a kidney that has stones.
Shenzhen, GuangdongAges 18–65 - NCT06793540Recruiting
Self-posture therapy for leftover kidney stone pieces
This trial tests whether simple posture exercises you can do at home can help clear small leftover stone pieces from the lower part of your kidney after standard stone treatment. It could spare you from needing more procedures.
LyonAges 18–70 - NCT02780297Recruiting
Study of rare stone-causing kidney conditions
This study is for people with certain rare kidney conditions that can cause kidney stones. It aims to learn how these conditions behave over time and may help improve future care.
Birmingham, AlabamaAges Any age - NCT06163313Recruiting
Kidney stone and tumor treatment study
This study looks at new ways to treat kidney stones and tumors in the upper urinary tract. It may help find better treatment options for these conditions.

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 - NCT03437057Recruiting
Aspirin after kidney stone treatment to prevent clotting
This study looks at whether taking a daily aspirin medicine during and after extracorporeal shockwave treatment for a kidney stone helps keep the blood from “clumping” too much. It will compare different maintenance approaches while monitoring safety, especially bleeding risk.
Clermont-FerrandAges 18 years+ - NCT03638999RecruitingEarly Phase 1
Aspirin or similar anti-inflammatory medicine for kidney stone stents
This early-phase study tests whether taking an anti-inflammatory medicine around the time of ureter stent placement can improve outcomes for people with kidney stones. It looks for participants who are getting a stent after a scope procedure and who can follow strict medication and health rules.

Gut microbes and sex risks for kidney stones after weight surgery
This study looks at how gut bacteria (microbes), along with sex, may affect the chance of getting kidney stones after bariatric (weight-loss) surgery. It may help doctors understand who is at higher risk so prevention can be improved.

Common questions
- Are there clinical trials for kidney stone?
- Yes. Clin2 currently lists 78 recruiting kidney stone 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 kidney stone 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 kidney stone 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.
