Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-surgical procedure that uses focused high-energy sound waves to break kidney or ureteral stones into small fragments that can then be passed naturally through the urine. It avoids surgery entirely and is performed as a day procedure. RRSH performed ESWL through its urology unit as part of the Phase I nephrology equipment.
Patients with kidney stones up to 2 cm in size located in the kidney or upper ureter, where the kidneys are functioning adequately and stones can be seen on X-ray or ultrasound.
You lie on a cushioned table. A lithotripter machine delivers shock waves focused on the stone — you may feel mild vibrations or tapping sensations. The procedure takes approximately 45–60 minutes under sedation or local anaesthesia. Most patients go home on the same day. Drink plenty of fluids afterwards to help pass the stone fragments.
Stop blood-thinning medications as directed by your doctor (typically 5 days before). Fast for 6 hours before the procedure. Strain your urine after treatment to collect stone fragments for analysis.
Covered under MJPJAY Scheme Code S9 (Urology).
