This study is tracking 238 adults who are already scheduled to have a procedure for kidney stones or an enlarged prostate (BPH) using Boston Scientific devices. The main goal is to see how often serious side effects happen with these tools in real-world use. Researchers will also…

This study tests a new technique called Burst Wave Lithotripsy (BWL) that uses bursts of low-amplitude ultrasound to break kidney stones into tiny pieces during a standard surgical procedure. About 40 adults scheduled for stone removal will receive BWL to see if it is safe and ef…

This study compares three different single-use flexible ureteroscopes used to remove kidney stones. Researchers will look at cost, how long the surgery takes, complications, and how well the stones are cleared. About 180 adults with small-to-medium kidney stones will take part.

This study compares two breathing machine settings during kidney stone surgery to see which one gives surgeons a clearer, steadier view inside the kidney. Sixty adults having elective surgery will be randomly assigned to either normal or low tidal volume ventilation. The goal is …

This study tests a simple change during kidney stone surgery: actively suctioning the kidney to collapse it at the end of the procedure, instead of letting it drain naturally. Researchers want to see if this reduces pain and infection right after surgery. About 90 adults with kid…

This study compares a new bendable tip-suction ureteral access sheath to a standard one during surgery for large kidney stones (staghorn stones). About 100 adults will be randomly assigned to one of the two sheaths. The goal is to see if the new sheath reduces complications and c…

This study compares two common treatments for kidney stones that are 1 to 2 centimeters in size. One treatment uses shock waves from outside the body to break up the stone, while the other uses a thin scope and laser through the urinary tract. Researchers will measure how complet…

This study tests whether two common blood pressure drugs, terazosin and tamsulosin, can reduce urinary symptoms like pain and urgency after a ureteral stent is placed. 150 adults in Malaysia will be randomly assigned to take one of the drugs or receive standard care for 14 days. …
