What is the right approach for Peyronie's disease surgery? Comparing postoperative wound complications between ventral and subcoronal incisions with penile straightening surgery.

BACKGROUND

Multiple guideline-based surgical treatment options for Peyronie's disease (PD) exist, including penile plication and plaque incision or excision and grafting. Surgical incision type may differ depending upon location and severity of curve, planned concomitant procedures, and surgeon preference.

AIM: To evaluate postoperative wound complications comparing outcomes between ventral and subcoronal incisions in patients undergoing tunica albuginea plication (TAP) and plaque incision or partial excision and grafting (PG) for PD.

METHODS

A single-surgeon, single-center retrospective chart review was conducted on all patients undergoing TAP or PG from 2019 to 2023. Patient demographics, including previous PD treatments, were recorded. A Mann-Whitney U test was utilized to determine differences in wound complication rate, median curvature improvement, and remaining postoperative curvature between ventral and subcoronal approaches.

OUTCOMES: Wound complication was classified as any dehiscence and/or wound exudate suspicious for infection within the first 3 months postoperatively. A secondary analysis was performed comparing these outcomes between TAP and PG.

RESULTS

In the analysis, 189 patients were included, including PD straightening surgery, including 125 patients who underwent TAP (66%) and 64 patients (34%) who underwent PG. Among all cases, 49.7% underwent ventral incision (N = 94) and 50.3% (N = 95) underwent subcoronal incision. A total of 12 patients (6.3%) experienced a wound-related complication postoperatively (range 3-23 days), including 9/94 (9.6%) in the ventral incision cohort and 3/95 (3.2%) in the subcoronal cohort (P = 0.081). All the patients were treated with oral antibiotics and two patients required closure under local anesthesia (both in the ventral incision cohort). Secondary analysis did not reveal any significant difference in outcomes between TAP and PG cohorts with respect to wound complications.

CLINICAL IMPLICATIONS: While we did not identify a statistically significant difference, most of our wound complications, including infection and/or dehiscence, were seen in those undergoing a ventral penile raphe incision. Despite this, the rate of wound complications with either incisional approach as low.

STRENGTHS AND LIMITATIONS: Our report represents a large cohort of patients treated with surgical straightening for PD, and to our knowledge is one of the first to compare wound complications between ventral and subcoronal incisions. Limitations include the retrospective single-surgeon series without randomization, lack of power analysis, and heterogenous classification of wound complications.

CONCLUSION

Both ventral penile raphe and subcoronal (degloving) incisions can be considered for penile straightening procedures to correct PD curvature deformity with a low risk for serious wound-related complications.
