How is minimally invasive surgery for urinary tract stones performed?

Minimally invasive surgery for urinary tract stones is an efficient and minimally invasive treatment method, mainly involving the following steps: 1. Anesthesia: Local or general anesthesia is selected according to the patient's condition to ensure a painless procedure. 2. Insertion of guidewire: A thin, long guidewire is inserted through the urethra to guide instruments during the surgery. 3. Urethral dilation: The urethra is dilated using the guidewire or a balloon catheter to facilitate instrument insertion. 4. Stone localization: The urethra and bladder are examined using instruments such as a cystoscope to accurately locate the stone. 5. Lithotripsy: The stone is fragmented into smaller pieces using techniques such as laser or ultrasound, facilitating its removal. 6. Stone removal: Stone fragments are removed from the body using instruments such as a guidewire or balloon catheter. 7. Completion of surgery: The urethra is cleaned and disinfected, the guidewire is removed, and the procedure is completed. The entire surgical process is minimally invasive and highly efficient, effectively treating urinary tract stones.
