Objectives
To investigate the long-term effects of Floseal® on erectile function recovery (EFR) after nerve-sparing robot-assisted radical prostatectomy (RALP).
Methods
We prospectively collected results of the self-administered International Index Erectile Function Questionnaire 1–5 and 15 (IIEF 1–5 and 15) of 532 consecutive patients who underwent RALP for prostate cancer in our institution between October 2007 and December 2015. Patients were divided into two groups according to Floseal® application after prostatectomy. They were enrolled according to the following criteria: (a) bilateral nerve-sparing procedure; (b) preoperative IIEF ≥ 17; adherence to our erectile rehabilitation protocol; (c) 1-year follow-up. Outcomes were measured as mean IIEF score, EFR (IIEF < 17 or ≥17), grade of ED: severe (IIEF < 17), moderate (17–21), mild (22–25) and no ED (>25).
Results
A total of 120 patients were enrolled. Group A included 40 consecutive patients who received traditional hemostasis, and Group B included 80 consecutive patients in which Floseal® was additionally used. No differences were observed in terms of preoperative mean IIEF score (p = 0.65). Group B patients showed a trend toward a higher mean IIEF score 3 months after surgery (p = 0.06) but no differences in terms of EFR (p = 1.000). Long-term results (6, 9, 12 months after surgery) showed a significantly and progressively higher mean IIEF score (p = 0.04, 0.003, 0.003) and EFR (p = 0.043, 0.027, 0.004) in Group A patients. Comparison between the groups in terms of severe, moderate, mild and no ED becomes significant at 9 and 12 months (p = 0.002, 0.006).
Conclusion
The results of our study suggest that local use of Floseal® worsens the long-term erectile function recovery in patients selected for nerve-sparing RALP.
