Abstract
OBJECTIVE: To determine the efficacy of intercostal nerve block and nephrostomy tract infiltration (NTI) with ropivacaine in patients undergoing tubeless percutaneous nephrolithotomy (TPCNL). MATERIALS AND METHODS:From February 2015 to March 2017, a total of 226 patients undergoing TPCNL were enrolled. After excluding 130 patients who failed to meet the inclusion criteria, a total of 96 eligible patients were randomized into 3 groups: group I, control group (n = 32); group II, intercostal nerve block with 15 mL of 0.5% ropivacaine and epinephrine (n = 32); and group III, NTI with 20 mL of 0.25% ropivacaine and epinephrine (n = 32). Pain status was assessed at postoperative 2, 8, and 24 hours and at discharge by visual analog scale score at rest (RVAS) and on deep breathing and coughing. RESULTS: Patient demographics and perioperative data between groups were comparable except for length of stay. Mean RVAS scores at postoperative 2 and 8 hours for group III were significantly less than those for group I (RVAS at 2 hours: 2.6 vs 4.9, P = .001; RVAS at 8 hours: 1.7 vs 3.3, P = .007). Mean RVAS scores at postoperative 24 hours had borderline significance (P = .050) among the 3 groups. Differences in mean deep breathing and coughing scores among groups were statistically significant (P = .002) only in the first 2 hours. All postoperative complications (5.4%, 5 per 92) were of grade 1 and not significantly different among groups. CONCLUSION:NTI is safe and effective in alleviating early postoperative pain for patients who underwent TPCNL.
