• Lithotripsy: This non-invasive procedure helps in breaking down kidney stones with the use of shock waves.
• Surgical Removal: It is large or hindering kidney stones or when conservative methods collapse.
• Drainage: Catheter insertion or drainage tube to alleviate urinary obstruction caused by conditions like hydronephrosis.
