Penile necrosis resulting from post-circumcision microwave diathermy: A report of 9 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent traditional circumcision for redundant prepuce or phimosis in other hospitals, followed by microwave diathermy for 30 - 60 minutes daily, which resulted in penile necrosis. With no response to conservative therapy, the patients were referred to our hospital at 3 -30 days postoperatively. Of the 9 patients, 5 presented with dry gangrene and 4 with moist gangrene. Six of the patients underwent partial penectomy, including 1 that received penis lengthening.3 months later, while the other 3 underwent total penectomy for total penile necrosis followed by penile reconstruction 3 months later, with deep inferior epigastric perforator (DIEP) flaps and by implantation of the 12th costal cartilage in 2 cases and with epigastric groin island flaps and by urethroplasty in the other.</p><p><b>RESULTS</b>The patients were followed up for 2 - 8 years, and all could urinate smoothly in the standing position. Of the 6 men treated by partial penectomy, 1 received penis lengthening and achieved a penile length of 7 cm and 5 had the remaining penile length of 3 -5 cm, 4 with erectile function and the other 2 capable of sexual intercourse. The 3 men treated by total penectomy achieved nearly normal external appearance of the penis, with a finalized length of (11.7 ± 1.3) cm, a circumference of (11.4 ± 2.1) cm, and a normal feel of the skin. Of the 3 cases of penile reconstruction, 2 achieved sufficient erectile hardness of the penis (grade 3) for sexual intercourse, while the other 1 remained impotent.</p><p><b>CONCLUSION</b>Post-circumcision microwave diathermy may result in penile necrosis, for the management of which, early debridement is necessitated and penile lengthening or reconstruction can be performed according to the severity of the lesion and needs of the patient.</p>

Surgical treatment of a rare case of penile squamous cell carcinoma in a 65-year-old man / 亚洲男科学杂志(英文版)

Penile squamous cell carcinoma has been commonly reported in the past decades. We describe a rare case of a huge squamous cell carcinoma of the penis in a 65-year-old patient with a 4-year history of tumor growth, for which total penectomy, perineal urethrostomy and bilateral inguinal lymphadenectomy were carried out. We suggest that aggressive surgical intervention should be recommended for those with well-differentiated penile carcinoma regardless of the size of the tumor.

Prevention and treatment of the complications of inflatable penile prosthesis implantation / 中华男科学杂志

<p><b>OBJECTIVE</b>To report the amelioration of the three-piece inflatable penile prosthesis (IPP) implantation and the prevention of its complications.</p><p><b>METHODS</b>Thirty-two patients with moderate to severe erectile dysfunction (ED) irresponsive to conservative treatments received the implantation of the three-piece IPP. The surgical techniques were ameliorated in the course of operation. The patients were guided in using the IPP after operation. The effects and complications of the implantation were observed based on IIEF of the patients before and after operation.</p><p><b>RESULTS</b>Sexual life was resumed and no complication was found in 28 of the patients. The complications that developed in the other 4 were pump failure (2 cases), urethral perforation (1 case), and penis contraction (1 case). The former 3 achieved normal sexual intercourse after the second operation. Comparison between the IIEF scores before and after operation showed a very remarkable difference (P < 0.01). The occurrence rate of complications was 12.5%. The satisfaction rate of sexual intercourse was 87.5% and the total satisfaction rate of sexual life was 84.4%.</p><p><b>CONCLUSION</b>The complications of the three-piece IPP implantation were obviously reduced by ameliorating operation techniques. The implantation of the three piece-IPP is safe and effective for advanced ED patients.</p>
