Penile rehabilitation after inflatable penile prosthesis (IPP) implantation for the treatment of erectile dysfunction includes leaving the device partially inflated so as to preserve the penile length and to maintain hemostasis.With a partially inflated device,the penis becomes more sensitive and more susceptible to unintended insults during the immediate postoperative management.The “Wang Collar,” a device intended to protect the penis in the early postoperative period,is hereby described.Three hundred and forty-eight patients had the “Wang Collar” included as part of their post-IPP management from August 2014 to February 2019.The protective collar,devised from a polystyrene cup with the bottom removed,is secured with a tape over the previously dressed and partially inflated penis.In order to evaluate the effectiveness of this device,we conducted surveys on the perioperative staff at three different institutions.The “Wang Collar” has been found to be beneficial in the early postoperative care of patients.Based on the answers to our questionnaire,the perioperative personnel.found this device to be highly protective,especially when transporting the patient after IPP surgery,easy to work with,and almost never bothersome or irritative to the patient.We present a novel penile device after IPP placement,which we have found to improve patient satisfaction in the postoperative period.In addition,it eases the care of the patient by the perioperative staff.It is now our routine to use this device after IPP surgery.Further research is necessary to evaluate whether this device can decrease postoperative wound complications.
