KIDNEY STONE

This study tested a device called Break Wave™ that uses focused ultrasound waves to break kidney stones into tiny pieces that can pass naturally. 64 adults with upper urinary tract stones (4-10 mm) received the treatment. The goal was to see if the device is safe and effective at…

This study tested a new tool called the CVAC System, a steerable catheter that helps remove kidney stones during a procedure called ureteroscopy. Thirty adults with kidney stones took part. The main goal was to see how safe the device is and how well it clears stones, measured by…

This study tested a new way to remove kidney stone pieces after laser treatment. Instead of using a tiny basket to grab each fragment, the SURE procedure gently vacuums them out. Researchers compared how many patients became completely stone-free with each method in 132 adults. T…

This study looked at 131 people having surgery for kidney stones. Some were already taking mirabegron for overactive bladder, which relaxes the ureter. Researchers wanted to see if this helped surgeons insert a tube more easily and caused less injury. The idea is that a relaxed u…

This study compared two FDA-approved lasers used to break up kidney stones during surgery: the newer SOLTIVE Thulium Fiber Laser and the standard Ho:YAG laser. About 100 adults with a single stone smaller than 2 cm took part. Researchers measured how well each laser cleared stone…

This study looked at two methods for removing kidney stones: laser dusting (breaking stones into tiny pieces that pass naturally) and basket extraction (using a small wire basket to remove fragments). Researchers compared how well each method cleared stones, how much pain patient…

This study tested a new technique to hold kidney stones in place during a minimally invasive surgery called mini-PCNL. The goal was to make the stone-breaking step faster and reduce leftover fragments. 45 adults with stones smaller than 4 cm took part. The study measured how long…

This study tested two ways to use a laser to remove kidney stones: breaking them into pieces or turning them into dust. Twenty adults with kidney stones took part. The goal was to see which method clears stones better, is faster, and causes fewer complications.

This study tested whether giving a single dose of pregabalin (Lyrica) before ureteroscopy—a surgery for kidney stones that often leaves a temporary stent in the ureter—can reduce pain and the need for opioid painkillers afterward. 118 adults were randomly assigned to receive eith…

This study tested a procedure called an erector spinae plane block to see if it could help with pain from kidney stones. Only 5 people took part, all of whom had already received one pain medication in the emergency room. The results are very early and not enough to draw firm con…

This study looked at how eating high or low amounts of oxalate (a natural compound in many foods) affects urine crystals and immune cells in healthy adults. Fourteen participants followed two controlled diets to see if oxalate changes crystal formation and immune function. The go…

This study tested a system called sipIT that uses a smart water bottle and phone app to track fluid intake and send reminders. The goal was to see if it helps kidney stone patients form a habit of drinking more fluids. 172 adults with a recent kidney stone diagnosis used the syst…

This study looked at 20 adults with and without kidney stones to find differences in blood and urine chemicals. Researchers measured neurotransmitters and gut bacteria byproducts to understand how metabolism may contribute to stone formation. The goal was to identify early warnin…

This completed trial compared two surgical procedures for removing kidney stones: standard PCNL and mini-PCNL. The study enrolled 18 adults with stones 10-20mm and measured blood loss, complications, and recovery time. The goal was to see if the smaller incision approach offers a…

This study tested a teaching program to improve nurses' knowledge and practice of infection control for patients having a procedure called percutaneous nephrolithotomy (PCNL) to remove kidney stones. Thirty nurses who care for these patients took part. The goal was to see if the …

This study followed 94 adults who have both recurrent urinary tract infections and kidney stones that are not blocking the kidney. Researchers wanted to see if surgically removing these stones reduces the number of future UTIs compared to just monitoring them. Patients chose with…

This study looked at 1,500 people who came to the emergency room with symptoms of a kidney stone and got a CT scan within 24 hours. Researchers wanted to know how many actually had a stone, where it was, and how big. They also checked whether having a fast CT scan changed how qui…
