Results: The visual analog scores for group 2 were significantly lower than (group 1) at 10, 20, 30 and 40 minutes till end of the procedure, (p <0.001). The mean requirements of supplemental fentanyl analgesia (μg) were significantly decreased in group 2 than group 1, (3.34 ± 7.32 versus 15.72 ± 6.41, p<0.001). All patients in group 2 were discharged earlier, 1 hour after the end of the procedure while 13 patients (26.5%) in group 1 had delayed discharge. No significant difference was detected between the two groups with regards to complete stone clearance after 1 month, no. of shocks, voltage power or duration of procedure. No patient in group 2 reported neurological side effects of local anesthesia. Conclusions: Lidocaine 1% by local infiltration cannot be used alone for pain relief but effectively reduced the analgesic needs and minimized hospital stay after renal ESWL, without affecting stone clearance.
