Clinical Trial Summary

This study is designed to compare analgesic effect of both the ultrasound (US)-guided QLB and ESPB blocks during ESWL and their effect on stone fragmentation.

Clinical Trial Description

Urinary tract calculi, one of the most common benign urological diseases, is seen in 12% of patients and has a recurrence rate of approximately 50%. Management of renal calculi is known to be affected by many factors, specially tolerance of pain during ESWL and how it is controlled. Pain experienced during ESWL is thought to occur when shock waves from the lithotripter reach superficial structures such as skin and also deeper structures such as the ribs, nerves and the kidney capsule. There are three main factors that contribute to the propagation of pain at these structures: shock wave (SW) pressure, distribution, and focal area size . Conventionally, pain during ESWL is managed by basic analgesics such as NSAIDs, which can also aid in stone clearance. Other methods of analgesia also have been studied and tested. Quadratus lumborum block (QLB) was first described by Blanco in 2007, it blocks T7-L1 nerve fibres in most of the cases. Studies have reported its use in the management of postoperative pain after hip surgeries. "Erector Spinae Plane Block" (ESPB) is another such block, that is increasingly tried for the management of postoperative pain for breast surgery, thoracic surgery, and also upper abdominal surgeries. ESPB when given at the lumbar region gives blockade from C7-T2 to L2-L3. ;
