Abstract
Objective
To evaluate the relationship between enlarged prostate, bulky median lobe (BML) or prior benign prostatic hyperplasia (BPH) surgery and perioperative functional, and oncological outcomes in high-risk (HR) prostate cancer (PCa) patients treated with Retzius-sparing robot-assisted radical prostatectomy (RS-RARP).
Methods
320 HR-PCa patients treated with RS-RARP between 2011 and 2020 at a single high-volume center. The relationship between prostate volume, BML, prior BPH surgery and perioperative outcomes, Clavien–Dindo (CD) grade ≥ 2 90-day postoperative complications, positive surgical margins (PSMs), and urinary continence (UC) recovery was evaluated respectively in multivariable linear, logistic and Cox regression models. Complications were collected according to the standardized methodology proposed by EAU guidelines. UC recovery was defined as the use of zero or one safety pad.
Results
Overall, 5.9% and 5.6% had respectively a BML or prior BPH surgery. Median PV was 45 g (range: 14–300). The rate of focal and non-focal PSMs was 8.4% and 17.8%. 53% and 10.9% patients had immediate UC recovery and CD ≥ 2. The 1- and 2-yr UC recovery was 84 and 85%. PV (p = 0.03) and prior BPH surgery (p = 0.02) was associated with longer operative time. BML was independent predictor of time to bladder catheter removal (p = 0.001). PV was independent predictor of PSMs (OR: 1.02; p = 0.009). Prior BPH surgery was associated with lower UC recovery (HR: 0.5; p = 0.03).
Conclusion
HR-PCa patients with enlarged prostate have higher risk of PSMs, while patients with prior BPH surgery have suboptimal UC recovery. These findings should help physicians for accurate preoperative counseling and to improve surgical planning in case of HR-PCa patients with challenging features.
