Abstract
Objectives
The aim of this study was to assess erectile function (EF) and urinary continence (UC) recovery after nerve-sparing retropubic radical prostatectomy (NS-RRPE) and nerve-sparing laparoscopic radical prostatectomy (NS-LRPE) depending on the neurovascular bundle (NVB) dissection technique used.
Methods
Twenty-four hour pad test was used to assess the degree of postoperative UC 1, 6 and 12 months after the surgery. For the purpose of EF assessment, International Index of Erectile Function-5 (IIEF-5) questionnaire was used. In addition, EF recovery assessment included the time needed to achieve a successful sexual intercourse with or without Inhibitors Phosphodiesterase 5 (IPDE5). A successful sexual intercourse was defined as an ability to achieve a strong erection enough for penetration and maintain erection for a long time, throughout the intercourse. Assessment was performed before the surgery and 8 and 6 months after the surgery.
Results
In the patient group with BNS + water jet dissection (WJD), the IIEF-5 score was considerably higher 8 weeks after the surgery (by 2.8 points) (р = 0.02). In 6 months, the difference between the group become more significant and reached 3.5 points (p = 0.01). Three months after urethral catheter removal, majority (95%) of patients in the NS-RPE + WJD group had no urinary incontinence (UI). For standard NS-RPE, that figure was 87%. Mild stress UI was observed in 5% of patients after NS-RPE + WJD and in 13% of patients after NS-RPE. Six months after urethral catheter removal, no significant differences in UC assessment were observed in the two groups.
Conclusions
The implementation of WJD of NVB in clinical practice has made it possible to considerably improve the quality of life for postoperative patients due to good outcomes in terms of early UC and EF recovery.
