Primary ureteroscopy for kidney stone blockage
Part of Kidney & urinary clinical trials.
This trial tests if using a scope to remove a ureteral stone (primary ureteroscopy) is safe and effective for patients whose kidney function has suddenly worsened due to the blockage. It aims to avoid putting in a temporary tube before the stone treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old
- You have a stone at least 5mm in size that is blocking one ureter (tube from kidney to bladder)
- The blockage has caused your kidney function to get worse recently (creatinine between 1.3 and 5 mg/dL)
- You have not already had a temporary tube (stent or nephrostomy) placed for this blockage
- You do not have any serious bleeding disorder, active infection in the urine, severe heart or lung problems, or other medical emergencies
- You do not have stones in both ureters or a pre-existing narrowing in the ureter below the stone

This trial tests a patient-centered approach to managing painful kidney/ureter stones that are blocking urine flow. It may help you choose the safest next step—such as treatment with a scope or careful observation—based on your symptoms and situation.
This study compares two ways to drain urine when a kidney stone completely blocks the ureter (the tube from kidney to bladder) in patients with only one working kidney. After your kidney recovers, doctors will remove the stone using a minimally invasive camera procedure.
This trial tests a new smart ureteroscope that controls pressure and temperature to remove kidney or ureteral stones while you have a urinary tract infection. It may offer a safer way to treat stones without needing to wait for the infection to clear.
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.
This trial tests a specific flexible scope (Shenzhen HugeMed 6.3 French) for removing kidney or ureter stones. It looks at how well it works, costs, and recovery, and may be a good option if you have stones smaller than 2.5 cm and need your first such 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.
