Objective assessment of early urinary continence by analysis and visualisation of intraoperative variables of radical robotic prostatectomies with a video editor.

Abstract

Abstract Introduction UI after RP is a factor that has a major impact on patients’ quality of life and the associated healthcare costs. The definition of UI is very variable in the literature. Similarly, a great many predictors have been studied that affect recovery of continence after surgery, the most important of which are intraoperative. Material and methods A retrospective and observational study performed between September 2008 and March 2015. We studied intraoperative factors through visualisation using a video editor of 148 patients who underwent robot-assisted radical prostatectomy, together with other perioperative factors associated with continence, and described in the literature. We assessed continence through ICQ questionnaires, urinary loss calculated by pad count, and clinical interview in the first, third, sixth month and at one year after surgery. We defined continence as not having to use a pad or using a pad for protection socially, or an ICQ\xa0≤\xa07. We used binary and lineal logistic regression analysis to study the relationship between the intraoperative and perioperative variables on urinary continence measured at the first, third, sixth month and one year after the operation, and on continence stability. Results In our study, 72.9% of the patients were continent at one year after surgery with a mean continence stabilisation time at 4.3 months. In our lineal logistic regression analyses we found no significant relationship with the continence variable analysed during the first year. In the lineal logistic regression analysis we found that tension-free sutures had a direct positive effect (p\xa0≤\xa00.05) on the stability time of continence, as well as the urinary losses measured in the first month after surgery. Conclusion In conclusion, we found in our study that the tension-free sutures were able to help towards early stability of continence. We found no other intraoperative predictors that influenced urinary continence. The urinary losses measured in the first month related to early recovery of continence.
