Abstract：Objective To evaluate the feasibility for confirming the preservation of the parasymphathetic nerve pathway during systematic nerve-sparing radical hysterectomy(SNSRH)using intraoperative electrical stimulation(IES).Methods Eighteen patients with cervical cancer and two patients with endometrial carcinoma underwent SNSRH.IES were performed on pelvic splanchnic nerve(PSN)while recording the electromyographyic(EMG)activity of the vesieal detrusor using neurological monitoring system.The residual urine at eighth day,the duration of postoperative catheterization,the first exhaust time and stool time were observed.Results Evokable potentials were recorded in 18 out of 20 patients.called IES-positive.Its residual urine at eighth day was(148.83±141.81)mL.The average duration of postoperative catheterization was(9.89±2.70)days.The first exhaust time and stool time were(60.29±22.73)and(104.29±37.60)hours respectively.For the remaining 2 IES-negative patients,the residual urine was 580mL and 210mL.The durations of postoperative catheterization were 19 and 25 days respectively.Conclusion During SNSRH,IES based on the measurement of EMG activity is a useful tool for confirmation of the preservation of the parasymphathetic nerve pathway innervating the bladder and prediction of the postoperative bladder function.
