Post operative pain control in percutaneous nephrolithotomy.

To evaluate post-surgery pain relief in percutaneous nephrolithotomy cases.The case-control study was conducted at Indus Hospital, Karachi, from July 2014 to July 2015, and comprised patients undergoing percutaneous nephrolithotomy. The patients were randomized by snose protocol into two equal groups of cases and controls. The cases were given peri-tubal local anaesthetic infiltration of 0.25% bupivacaine, while the controls were given 10ml 0.9% normal saline infiltration. Post-operative pain was assessed using visual analogue scale.Of the 68 patients, there were 34(50) in each of the two groups. Pain score was significantly less in the intervention group post-operatively at 6th and 12th hours (p<0.05). Also, total consumption of analgesics and demand of analgesic medication were also significantly low among the cases (p<0.05).Bupivacaine infiltration into the peri-tubal track significantly reduced post-operative pain.
