Long-term outcomes after plaque excision grafting for Peyronie's disease and subanalysis of patients who undergo the procedure despite preoperative counseling against it.

Abstract

Plaque excision and grafting (PEG) has been recommended for patients with Peyronie's disease (PD) with >60° curvature and/or hinge effect and strong preoperative erections, while placement of an inflatable penile prosthesis (IPP) is recommended when rigidity is suboptimal. Nevertheless, many patients counseled to undergo an IPP decline and insist on proceeding with PEG due to personal preference or desire to avoid an implant. We aim to review long-term outcomes in patients who underwent PEG for PD at our institution and investigate whether there is any difference in long-term outcomes in patients who undergo PEG despite a recommendation to undergo IPP. We conducted a retrospective chart review from 2007 to 2021 on PEG surgery performed at a single tertiary care institution in patients ≥18years old who had >3months of follow-up. Postoperative information was gathered from the electronic medical record, including postoperative erectile function, patient satisfaction, and the ability to engage in penetrative sexual intercourse. An overall 251 patients underwent PEG with a median follow-up of 12 months (IQR, 6-54). Among these, 54 (22%) were initially advised to undergo IPP but elected for PEG. Patients who underwent PEG despite counseling to undergo IPP reported lower postoperative ability to engage in intercourse (51% vs 76%). Seven (13%) patients initially advised to undergo IPP eventually received an IPP, relative to 7 (4%) initially advised to undergo PEG. Thorough preoperative assessment of erectile function and penile deformity can guide clinician counseling and manage patient expectations during decision making between PEG surgery and IPP implantation for PD. Limitations of this study include its retrospective nature, high attrition to follow-up, and risk of recall and selection bias. This is a large study with a median follow-up of 12months, with a high-volume single surgeon who treats patients in a specialized population of complex cases. Patients who were initially counseled to undergo IPP due to suboptimal erectile rigidity but elected for PEG had worse postoperative ability to engage in penetrative intercourse, and a higher proportion of these patients eventually received an IPP.
