Introduction:
The sliding technique (ST), commonly done with a subcoronal circumcising incision with penile degloving, has been used to restore penile size in patients with severe Peyronie's disease (PD) and erectile dysfunction, but with a potential risk of ischemic injury to the glans penis.
Aim:
To provide detailed surgical techniques regarding the nondegloving ventral incision and report our initial experience with this approach to perform the ST and penile prosthesis placement in patients with severe PD.
Methods:
This was a retrospective review of patient outcomes after penile prosthesis placement with penoplasty for severe PD and erectile dysfunction from January 2015 to December 2017.
Main Outcome Measures:
Primary outcomes included straightening rates, penile measurement, along with immediate and late complications. Secondary outcomes include operative time and overall patient satisfaction.
Results:
12 Patients had significant penile atrophy and/or curvature >60 degrees and underwent inflatable penile prosthesis placement with grafting procedure. Significant penile atrophy was determined by a combination of the patient's subjective report and the surgeon's objective assessment through stretched penile length. 7 (58.3%) of those patients underwent ST, of which the last 5 had the procedure performed through a nondegloving ventral incision. Mean degree of curvature prior to ST was 66 degrees (45-90 degrees). Mean penile length gain was 2.6 cm (2.0-3.0 cm). At a mean follow-up of 15.5 months (3-31 months), only 1 patient had minimal residual curvature of 15 degrees. There were no vascular complications.
Clinical Implications:
This nondegloving technique theoretically maintains blood flow continuity to the glans penis by preserving the continuity of the skin, dartos fascia, and neurovascular bundle.
Strengths & Limitations:
Strengths of this study include the novel nature of this approach, no incidence of vascular complications, and adaptability to other grafting procedures during penile prosthesis placement. Limitations include the use of 5-item International Index of Erectile Function scores to assess preoperative erectile function on PD, small population, longer incision, and a possible steep learning curve.
Conclusion:
While ischemic complications of ST and penile prosthesis implantation are rare, there are reports of ischemic injury in patients undergoing a subcoronal circumcising incision with penile degloving. The non-degloving technique with ventral incision provides for an alternative method for ST and penile prosthesis placement to maintain dartos and skin continuity to the glans penis while still allowing for adequate surgical exposure.
