Abstract

Introduction
Medications, namely antiplatelets (AP) and anticoagulation (AC), are effective at avoiding fatal vascular complications and prolonging the lives of our patients. As such, more and more men seeking treatment for erectile dysfunction (ED) also take blood thinners. This is an interaction we must better understand to provide safe, individualized care to our patients and minimize peri-operative morbidity. Currently, there is no published information on whether differences exist in the escalation of treatment for patients with erectile dysfunction and on AC. A previous study has demonstrated no statistically significant difference in complications between AC and non-AC groups while on ICI, despite there being a higher rate of absolute bleeding events for AC patients.

Objective
To compare outcomes and complication rates in patients undergoing IPP implantation following ICI therapy with or without concurrent anticoagulation.

Methods
A retrospective observational study was undertaken. Electronic patient records from January to September 2021 were reviewed. Included patients were those who had either currently or previously utilized ICI therapy for ED treatment. ICI therapy surveys and Erectile Dysfunction Inventory for Treatment Satisfaction (EDITS) questionnaire were obtained. 85 patients met the inclusion criteria; 43 concurrently using AC during ICI therapy and 42 with no AC use. Patients who were unable to completely stop their AC medications a week before surgery due to cardiovascular concerns or recommendations, underwent bridging with a shorter half life and reversible AC. Extra measures taken during the IPP for such patients, including meticulous hemostasis, compression dressing and drain insertion. Additional data regarding IPP implantation as well as any complications or infections experienced following IPP surgery which were compared between the AC and no AC groups.

Results
Patient demographics, IPP implantation information and subsequent complication rates are listed below in Table 1. There was no statistically significant difference in the rate of patients who underwent IPP placement between the AC and no AC cohorts. Moreover, there was also no statistically significant difference in median time from date of initial ICI usage to time of IPP placement as well as median time from IPP placement to last follow-up. Among the 12 total patients who underwent IPP placement, none experienced any complications, including infection, mechanical failure, device removal or revision at any time point up to last follow-up (longest was 18 months). No statistically significant differences in EDITS score between both groups was observed.

Conclusions
These preliminary findings, while requiring large-scale follow up, show that there is no statistically significant difference in rate of patients opting for IPP surgery following initiation of ICI therapy regardless of concomitant AC usage as well as the rate of complications following IPP implantation. Lastly, there is no drawbacks in performing such procedure in this specific cohort of patients, provided that all necessary measures are taken into consideration to minimize bleeding complications.
