With the popularization of ureteroscopy, ureteral avulsion has become a common complication of urological surgery in recent years. In the study, we reviewed the clinical management of 2 patients who underwent emergency ureterostomy and selective operation of ileoureteral substitution, emergency repair and selective operation of Boari-flap ureteroneocystostomy respectively. After 22 and 17 months of follow-up, no ureter stricture were found, and hydronephrosis were relieved compared with preoperative in both.

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.
