Penile prosthesis implantation in cases of severe Peyronie's disease may require plaque excision/incision and grafting, which may require mobilization of the neurovascular bundle or urethra, posing the risks of penile hyposensitivity or urethral injury, and is time-consuming, possibly increasing infection risk.
Evaluating transcorporeal debulking of Peyronie's plaques by "Shaeer's punch technique."
Penile prosthesis implantation and punch technique (PPI-Punch) was performed for 26 patients. After corporotomy and dilatation, Peyronie's plaques were punched out from within the corpora cavernosa using the punch forceps, and then a penile prosthesis was implanted. Comparison to a matching retrospective group of 18 patients operated upon by plaque excision-grafting and penile prosthesis implantation was performed.
The study outcomes were straightness of the erect penis, complication, satisfaction with length on a 5-point scale, the International Index of Erectile Function-5, and the Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire.
Average preoperative curvature angle was 58.1 ± 11.7 in the Punch group and 58 ± 14.8 in the excision-grafting group, p=0.99. After surgery, all patients had a straight penis. No tunical perforations, urethral injuries, or extrusions were noted. Average additional operative time for Punch technique ranged from 5 to 10 minutes (7.3 ± 1.7), in contrast to the excision-grafting group where plaque surgery duration was 50.8 minutes ± 11.1, an 85% difference, p < 0.0001. Septal plaques in the latter group could not be removed. In the PPI-Punch group, penile sensitivity was preserved in all patients, compared with the excision/grafting group, with 7 of 18 patients reporting hyposthesia of the glans. Infection occurred in 1 of 26 patients in the PPI-Punch group, compared with 2 of 18 patients in the excision/grafting group. Satisfaction with length on a 5-point scale was 3.8 ± 0.9 in the punch group, versus 3.1 ± 1.1 in the excision-grafting group, p=0.009.
The proposed technique is minimally invasive and prompt, possibly decreasing the known complications of plaque surgery and PPI including sensory loss.
One limitation is the inability to accurately measure preoperative erect length in patients with erectile dysfunction with poor response to intracavernous injections.
Shaeer's punch technique is a minimally invasive procedure for transcorporeal excavation of Peyronie's plaques before penile prosthesis implantation, omitting the need for mobilization of the neurovascular bundle or spongiosum, and hence, there is low or no risk for nerve or urethral injury and brief plaque surgery time.
