ClinConnect Summary

This clinical trial is studying a new approach to treating kidney stones using a procedure called ureteroscopic lithotripsy, which breaks up stones in the urinary tract. The researchers want to find out if patients can safely go home without a urinary catheter, which is a tube that helps drain urine from the bladder. The trial will compare two groups of patients: those who have the ureteroscopic procedure with a catheter and those who do not, focusing on their pain levels and how urgently they need to urinate after the procedure.

To participate in this trial, patients should be between 18 and 70 years old and have normal kidney function. They must be undergoing a specific type of surgery to remove kidney stones, but certain health issues like severe heart or lung diseases, or past surgeries that affect the urinary system, may prevent them from joining. Participants can expect close monitoring of their recovery and will help researchers understand if avoiding a catheter can reduce discomfort after surgery. This trial is currently not recruiting participants, but it aims to provide important insights into improving care for kidney stone patients.
