Recruiting studies
- NCT03305835Recruiting
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 - 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 - NCT05866081Recruiting
Testing whether to skip a stent after kidney stone procedures
This trial studies whether some people can avoid getting a ureteral stent after ureteroscopy and lithotripsy for a kidney stone. It may help reduce stent-related discomfort while still keeping outcomes safe for the stone problem.
Tucson, ArizonaAges 18 years+ - NCT05738304Recruiting
Do we need a stent after kidney stone surgery?
This study looks at whether placing a temporary tube (called a stent) in the ureter after kidney stone surgery is always necessary. Some patients get a stent to help urine flow, but it can cause discomfort. The trial aims to see if skipping the stent is safe and leads to fewer symptoms. If you are having kidney stone surgery, participating might help determine the best approach for recovery.
CairoAges 18 years+ - NCT07866209Recruiting
Comparing two devices for kidney stone surgery
This trial compares two different tubes used during surgery to remove kidney stones. The goal is to see if one type works better than the other for clearing stones safely.
Antalya, MuratpasaAges 18 years+ - NCT07718802Recruiting
Watching vs surgery for kidney stones in children
This study compares simply watching a kidney stone over time versus having surgery to remove it, in children and teens who have a small, symptom-free stone. The goal is to see which approach leads to better health outcomes.
Minneapolis, MinnesotaAges 6 years+ - 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+ - 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 - 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+ - 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+ - 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 - 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 - 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 - 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 - NCT05237063Recruiting
Predicting kidney stone recurrence and complications using precision medicine

AmiensAges 18 years+ - 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.

Urgent urine drainage before kidney stone surgery
This study looks at patients who have kidney stones and a urinary tract infection that spreads to the blood. It compares two ways to drain urine urgently before the main stone removal surgery, to see which leads to better outcomes.
