Recruiting studies
- NCT07138872Recruiting
Comparing heart health in kidney stone surgery positions
This trial compares how lying on your stomach versus your back during kidney stone removal affects blood flow and heart function. It may help doctors choose the safest position for you.
IstanbulAges 18–80 - NCT07753733Recruiting
Comparing one versus multiple tunnels for complex kidney stone removal
This trial compares two ways to remove complex kidney stones through a small cut in the back. It uses a special scope to see inside the kidney, and some patients get one or multiple small tunnels to reach the stones. The goal is to see which method is safer and more effective.
CairoAges 18–70 - NCT07697677Recruiting
Mini versus standard surgery for complex kidney stones
This study compares two ways to surgically remove large or complex kidney stones. It tests whether a less invasive approach works as well as the standard surgery, with the goal of reducing recovery time and complications.
Guangzhou, GuangdongAges 18–70 - NCT07159503Enrolling by invitation
Comparing two procedures for 2-4cm kidney stones
This trial compares two methods to remove kidney stones that are 2-4 cm in size: one uses a thin tube through a small cut in your back (VISOR), and the other uses a larger cut (PCNL). The goal is to see which approach works better and has fewer side effects.
Hangzhou, ZhejiangAges 18–80 - NCT07058402Recruiting
Comparing two kidney stone surgeries for medium stones
This trial compares two different surgeries for removing a single kidney stone that is 2 to 3 centimeters in size. One method uses a flexible scope with a suction tube, and the other uses a small incision in the back. The goal is to see which works better and has fewer side effects.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06266793Enrolling by invitation
Holmium vs. thulium laser for mini kidney-stone surgery
This study compares two lasers (holmium and thulium) used during mini PCNL surgery to remove kidney stones. If you are scheduled for this surgery and have a stone between 1 and 3 cm, you may be able to join and help doctors learn which laser works better.
Portland, MaineAges 21–90 - 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 - NCT06797466Recruiting
3D guided planning for large kidney stone surgery
This study tests a new 3D computer model to help surgeons plan a procedure called PCNL for removing large kidney stones. It may help make the surgery safer and more effective.
AdıyamanAges 18 years+ - NCT04669886Recruiting
Blood test before kidney stone surgery to predict infection risk
This study looks at a blood test done before percutaneous nephrolithotomy (PCNL), a procedure to remove kidney stones. The goal is to see whether results can predict who is more likely to develop infections or strong whole-body inflammation after surgery.
Miami, FloridaAges 18 years+ - NCT07363681Recruiting
Comparing Two Anesthesia Methods for Urological Surgery
This study compares two types of anesthesia during urological surgery: inhaled gases versus a medicine called dexmedetomidine. The goal is to see which one helps you recover more smoothly in the recovery room.
Istanbul, IstanbulAges 39–99 - NCT05993546Recruiting
Comparing two sheath types for mini kidney stone surgery
This study compares two types of sheaths (tubes) used during a small-incision kidney stone surgery. The goal is to see if a vacuum-assisted sheath works better than the standard one to remove stones.
Cleveland, OhioAges 18 years+ - NCT07523074Recruiting
Early vs. delayed shock wave treatment for leftover kidney stones
This trial compares two timing schedules for using shock waves to break up small kidney stones that remain after a surgical procedure. The goal is to find the best time to treat these leftover stones to help them pass naturally and prevent complications.
Banī Suwayf, Beni-Suef GovernrateAges 18–70 - NCT06274333RecruitingPhase 3
Easing bladder discomfort after kidney stone surgery
This trial tests if adding dexmedetomidine or tramadol to standard paracetamol can reduce bladder pain and discomfort from the urinary catheter used during kidney stone removal. It may help patients feel more comfortable after their procedure.
Cairo, Cairo GovernorateAges 20–50

Common questions
- Are there clinical trials for percutaneous nephrolithotomy (pcnl)?
- Yes. Clin2 currently lists 13 recruiting percutaneous nephrolithotomy (pcnl) 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 percutaneous nephrolithotomy (pcnl) 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 percutaneous nephrolithotomy (pcnl) 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.
