Abstract:
Objective To evaluate the recovery rate of erectile function (EF) and identify various factors predicting the recovery of EF in men undergoing laparoscopic radical prostatectomy (LRP) in our center.Methods From January 2011 to December 2012,a total of 106 men with localized prostate cancer underwent LRP in our center by one surgeon were included,and we gathered the preoperative EF condition and perioperative factors,such as patients' age,comorbidity and surgical procedure,et al.We followed up all the patients by telephone in August 2013 to collect the EF recovery data of these paticnts after LRP,with the mean follow-up of 18 (8-31) months.We analyzed the perioperative factors in order to predict the EF recovery after LRP.Results A total of 60 patients with preoperative sexual activity were included,and there was no difference in baseline data compared with other cases.Recovery of potency was defined as postoperative penile erection.The recovery rate of EF was 46.7% (28/60) without the use of any drugs or devices for erection assistance.In our study,the recovery rate of EF in age ≤60 years was 90.0% (9/10),and it was better than other two older groups (P =0.001).In patients whose preoperative IIEF-5 score was 22-25,the recovery rate of EF was 66.7% (8/12),and it was better than those with IIEF-5<22 (P=0.006).The recovery rate of EF in patients with preserved neurovascular bundle was 53.1% (26/49) and it was 83.3% (5/6) in patients with preserved accessory pudendal artery,which was better than those without preservation (P=0.036 and P =0.023).Conclusions In our study,age and preoperative EF were the significant factors to predict potency recovery,and preservation of neurovascular bundle and accessory pudendal artery during LRP were the positive predictor factors.
