BackgroundFor management of postoperative bladder spasm by the ureteral reimplantation, general anesthesia and epidural anesthesia are selected in many hospitals, but epidural anesthesia is not a common technique for various complications and risks. We examined whether postoperative bladder spasms can be prevented by general anesthesia combined with single shot caudal anesthesia.MethodsWe studied 18 patients undergoing ureteral reimplantation. Premedicated by diazepam syrup (0.5 mg x kg(-1), maximum dose 10 mg). In combination with caudal anesthesia with 0.3% ropivacaine (3 mg x kg(-1), maximum dose 60 mg), general anesthesia was maintained with oxygen, nitrous oxide and sevoflurane. For the evaluation of pain relief we used face pain scale when the patients returned to the ward, postoperative 5 hours, 24 hours and at discharge.ResultsAt postoperative 5 and 24 hours, some patients had a pain scale of above 3. But, those under pain scale 1 was 83%. At discharge, all patients were evaluated as pain scale 0 or 1.ConclusionsGeneral anesthesia combined with single shot caudal anesthesia suppressed postoperative bladder spasm. All patients were discharged within 3 postoperative days.
