Pain was radiating to groin in 88 (75.86%) patients and to genetelia in 37 (31.89%) patients. Costovertebral angle tenderness was found in 103 (88.79%) patients. 98 (84.48%) patients had pain relief within 60 minutes of injection lidocaine. 18 (15.52%) patients had no pain relief at 60 minutes of injectable lidocaine and were given rescue analgesics.
