- W4377246502 abstract "Abstract Introduction Erectile dysfunction continues to be a concern for patients and physicians after surgical treatment of prostate pathology. Objective To analyze doppler diagnosis on patients who underwent prostate surgery for benign or malignant pathology of the prostate. Methods We retrospectively analyzed all patients who underwent either robotic assisted prostatectomy (RALP), open retropubic prostatectomy (RRP), endoscopic procedures such as greenlight procedure, laser resection of the prostate or transurethral resection of the prostate (TURP); and High Intensity Focused Ultrasound (HIFU) treatment for prostate pathology and who underwent intracavernous injection followed by Color Doppler Duplex Ultrasound (CDDU) at our institution between 2005 and 2019. CDDU findings were recorded following injection of low dose alprostadil (10-20 mcg) and again after a period of privacy and visual sexual stimulation. CCDU findings including peak systolic velocities (PSV), and resistive indices (RIs) were recorded. Arterial insufficiency (AI) was defined as either a post-stimulation PSV < 25 with any RI or a PSV 25-34.9 with RI≥0.9. Cavernous Venous Occlusion Disease (CVOD) was defined as post-stimulation PSV ≥35 with RI < 0.9. Mixed was defined as post-stimulation PSV 25-34.9 with RI < 0.9. Vascular normal was defined as post-stim PSV ≥ 35 with RI ≥ 0.9. Results 380/1917 (19.8%) patients had a past surgical history of prostate surgery. 111/380 (29.2%) underwent RRP, 168/380 (44.2%) patients underwent RALP, 85/380 (22.3%) underwent endourological resection of the prostate and 2/380 (0.5%) patients underwent HIFU. Median age for the RALP group was 60.5 (IQR 23.7-82.8), RRP group was 64.2 (29.7-87.7), endourological resection of the prostate 64.6 (30.8 – 85.6) and HIFU 65.0 (46.9-79.4). 87.1% of patients who had an endoscopic procedure were using phosphodiesterase-5 inhibitors at the time of CDDU. CVOD was the most common etiology of ED in patients who underwent RRP (28.8%) and Endourological procedures of the prostate (32.9%); In patient who underwent RALP the most common etiology of ED was noted to be AI (28.6%), however none of these values were statistically significant (p=0.428). Conclusions There is no difference in etiology of ED in patients who underwent open, robotic or endoscopic manipulation of the prostate as shown by CDDU. Disclosure No" @default.
