Does flexible ureteroscopic surgery for kidney stones cause harm to the kidneys?

Flexible ureteroscopic lithotripsy, also known as percutaneous nephrolithotomy, may potentially cause some degree of kidney damage, although the extent largely depends on various factors. Improper manipulation during the procedure may lead to injury of the kidney or surrounding tissues, manifesting as symptoms such as hematuria and flank pain. Additionally, if patients do not receive timely and effective treatment, complications such as urinary tract infections or glomerulonephritis may develop, which could impair renal function. However, these risks are not universally present, and with advances in medical technology, the safety of the procedure has significantly improved. Flexible ureteroscopic lithotripsy is a relatively safe and effective treatment for kidney stones. Nevertheless, patients should adhere to proper postoperative care and undergo regular follow-up examinations to minimize potential kidney damage as much as possible.
