- 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+ - NCT03873259Recruiting
Testing a new way to check kidney stones during surgery
This trial tests a method called burst wave lithotripsy (BWL) to help doctors assess and treat kidney stones during a planned ureteroscopy procedure. It may help surgeons confirm how well the stone is being broken while you are on the operating table.
Carmel, IndianaAges 18 years+ - NCT06942949Recruiting
Testing a new sound wave device for kidney stones
This study tests a new device that uses sound waves to break up kidney stones in the ureter. It may help people with a single stone of moderate size, as an alternative to surgery or standard shock wave treatment.
Phoenix, ArizonaAges 21 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 - NCT07617909RecruitingPhase 2
L-Citrulline vs. Tamsulosin for Kidney Stone Passage
This study tests whether L-citrulline (a natural amino acid) or tamsulosin (a common blood pressure medication) helps you pass a small kidney stone stuck in your ureter (the tube from kidney to bladder) without surgery. The goal is to compare which medicine works better and is safer.
Banī Suwayf, Beni Suweif GovernorateAges 18–60 - NCT07559721Recruiting
Understanding Inflammatory Polyps in Kidney Stone Surgery
This study looks at what causes inflammatory polyps (growths) to form in the ureter when you have kidney stones. By understanding these risk factors, doctors hope to better predict and prevent complications during stone removal surgery.
Changchun, JilinAges 18–80 - NCT07310797RecruitingPhase 4
Comparing two drugs to help pass a ureter stone
This trial tests two medications, mirabegron and tamsulosin, to see which works better for helping a single ureter stone pass without surgery. If you have a stone between 4 and 10 mm in size, are 18-75, and have good kidney function, this study may be for you.
New Taipei CityAges 18–75 - NCT07617922RecruitingPhase 2
Melatonin and solifenacin for ureteral stent discomfort
This study tests whether two medications—melatonin (a sleep aid) and solifenacin (a bladder-control medicine)—can reduce uncomfortable symptoms from a temporary plastic tube (ureteral stent) placed in your urinary system during kidney stone treatment. The goal is to find out if these drugs help you feel better while the stent is in place.
Banī Suwayf, BeniSuefAges 18–60 - NCT07617948RecruitingPhase 2
Aminophylline injection to help place ureteral stent for kidney stone blockage
This trial tests whether injecting aminophylline (a medication that relaxes muscles) into the bladder can help doctors place a stent (small tube) to relieve a blocked ureter caused by a kidney stone. The goal is to improve kidney function when one kidney is blocked and not working.
Banī Suwayf, Beni Suweif GovernorateAges 18 years+ - NCT05574517Recruiting
Tubeless kidney stone surgery without a ureter tube
This trial looks at a kidney-stone operation done through the back of the body (“percutaneous nephrolithotomy”) but without placing tubes after surgery. It may help patients with certain stone sizes by reducing the need for drainage equipment, but eligibility depends on stone type and your health.
Hengyang, HunanAges 18–80 - NCT07773090Recruiting
Stenting before mini-keyhole kidney stone surgery
This trial is looking at whether placing a small tube (stent) in the ureter before a type of keyhole surgery for kidney stones helps with outcomes like pain and success of the procedure. It aims to see if this pre-treatment makes the surgery easier, potentially reducing complications and improving stone removal.
CairoAges 18–70 - 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+ - NCT06667557Recruiting
Comparing Two Lasers for Kidney Stone Breaking
This trial compares two types of lasers used to break up kidney and ureter stones during a ureteroscopy procedure. The goal is to see which laser works better at breaking stones into smaller pieces.
Shanghai, Shanghai MunicipalityAges 18–70 - 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 - NCT02298465Recruiting
Shockwave treatment for a kidney stone: lying down two ways
This trial studies whether kidney-stone shockwave treatment works better when you lie on your back (supine) versus on your stomach (prone). It focuses on adults with a stone in the lower part of the urine tube (the distal ureter).
Hong KongAges 18 years+ - NCT06158620RecruitingPhase 1/Phase 2
Nasal spray for pain after ureter stent placement
This trial tests whether a nasal spray form of the painkiller ketorolac can safely reduce pain from a ureteral stent after stone surgery. If you are having a ureteroscopy with stent placement, this might help you manage discomfort without stronger medications.

Common questions
- Are there clinical trials for ureteral calculi?
- Yes. Clin2 currently lists 16 recruiting ureteral calculi 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 ureteral calculi 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 ureteral calculi 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.
