Implantation of a prosthetic penis generally refers to penile prosthesis implantation, a surgical treatment for erectile dysfunction in men. The treatment process includes preoperative evaluation, preoperative preparation and surgery, and postoperative care. 1. Preoperative evaluation: Penile prosthesis implantation is an irreversible surgery, so preoperative evaluation is very important. The evaluation process requires a comprehensive review of the patient’s medication history, surgical history, and sexual life history, which is valuable for evaluating the therapeutic efficacy, selecting the appropriate prosthesis, identifying contraindications, and reducing the probability of adverse events. 2. Preoperative preparation and surgical treatment: Anesthesia can be in the form of general, local, or spinal anesthesia, with the anesthesiologist deciding on the specific modality. Preoperatively, the patient is bathed with antimicrobial chlorhexidine application, and the surgery is performed in the supine position. The surgical procedure is simply divided into the placement of the cylinder, the placement of the control pump, the placement of the reservoir capsule, and the final closure of the incision. 3. Postoperative care: Drainage tubes and urinary catheters are removed on the first postoperative day. Prophylactic antibiotics can be administered postoperatively, with the usual regimen being a 7-day regimen of quinolone antibiotics (ofloxacin, levofloxacin, etc.). The patient avoids compression of the scrotum by sitting for one week postoperatively. At two weeks postoperatively, an initial follow-up visit is performed to observe wound healing, etc. For patients with erectile dysfunction, they should go to the relevant departments of regular hospitals and be treated under the guidance of specialized physicians. Penile prosthesis implantation is a very professional operation, which must be carried out by qualified professional physicians, and patients should not operate on their own or find unqualified personnel to operate.
