Kidney stones are a urological condition requiring treatment at a hospital's urology department. Diagnosis involves imaging, such as ultrasound or CT scans, to determine the stone's exact size and location for appropriate treatment. If the stone is relatively small, with a diameter of six millimeters or less, referred to as a small stone, it generally does not require special treatment. Increased fluid intake, frequent urination, and exercise can help facilitate the expulsion of the stone. If the stone's diameter is between 0.7 and 1.5 centimeters, extracorporeal shock wave lithotripsy or ureteroscopy may be considered. For larger stones exceeding 1.5 centimeters, possibly accompanied by hydronephrosis, the recommended treatments are percutaneous nephrolithotomy or open surgery for stone removal.
