Objective  To analyze the efficacy of evidence-based nursing intervention for pain in treatment of patients with minimally invasive surgery for ureteral calculi.

  Methods  Totally 116 patients with minimally invasive surgery for ureteral calculi were selected and divided into evidence-based group (n=58) and routine group (n=58) by block random method. The routine group received routine nursing intervention for minimally invasive surgery, while the evidence-based group received evidence-based nursing intervention for pain on the basis of the routine group. Both groups were intervened until discharge, and were followed up for 6 months. The pain degrees at 1 hour, 2 and 3 hours after operation were observed in both groups, and the postoperative rehabilitation condition (time to bed-off activity and hospital stay) as well as the compliance behavior and knowledge awareness after follow-up were compared between two groups. Pain control satisfaction degree and self-management ability on the 5^th day after operation were compared between two groups.

  Results  At 1 hour, 2 and 3 hours after operation, the Visual Analogue Scale (VAS) scores in both groups decreased gradually, and the VAS scores of the evidence-based group at 2 and 3 hours after operation were significantly lower than those of the routine group (P < 0.05). On the 5th day after operation, the scores of pain affecting daily life, pain expectation, pain affecting emotion and pain experience in the evidence-based group were significantly lower than those in the routine group, while the scores of living habits, diet control, medication, emotion management, perception status of pain control education and perception status of pain control were significantly higher than those in the routine group (P < 0.05). The time to bed-off activity and hospital stay in the evidence-based group were significantly shorter than those in the routine group (P < 0.05). After follow-up, the compliance behavior rate and knowledge awareness rate in the evidence-based group were 94.83% and 96.55% respectively, which were significantly higher than 75.86% and 77.59% in the routine group (P < 0.05).

  Conclusion  Evidence-based nursing intervention for pain can alleviate the postoperative pain of patients with minimally invasive surgery for ureteral calculi, improve pain control satisfaction degree, self-management ability, compliance rate and knowledge awareness rate, so as to promote postoperative rehabilitation.
