Abstract
Introduction Controlling bleeding without disturbing the anatomy and function of the structures in the prostate bed remains a significant challenge during radical prostatectomy (RP). Materials and methods Five grams of powdered microporous polysaccharide haemospheres (MPH) was applied to the prostate bed at the end of robot-assisted RP in 422 consecutive patients. Continence was defined as no pads and potency as the ability to have penetrative sex with or without PDE5 inhibitors in previously potent, non-diabetic men aged <70 years following bilateral intra- or inter-fascial neurovascular bundle (NVB) preservation. Results In total, 95.3% of patients had nerve preservation and the mean operating time and blood loss were 142 minutes and 200ml, respectively. There were no intraoperative complications, and the postoperative transfusion rate was 0.2%. The mean hospital stay was 1.7 nights, and duration of catheterisation was 12 days. Final pathology demonstrated a mean prostate weight of 40.0g and 14.5% replacement by cancer, most commonly Gleason 7. The positive surgical margin rate for pT2 tumours was 10.0%. Biochemical recurrence was 2.1% at a mean follow-up of 18.0 months. Continence and potency rates at 4 weeks and 1 year after surgery were 76.4% and 97.7% and 27.8% and 78.1%, respectively. The trifecta and pentafecta rates 1 year after surgery were 53.1% and 45.8%. Discussion and conclusion Powdered MPH applied to the prostate bed at the end of robot-assisted RP appears to be a safe, easily applied and useful adjunct to conventional haemostasis. The suggestion that it might also improve the functional outcomes of RP merits further investigation in the context of a randomised trial.
