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>

Hand-assisted-drawing-needle running suture with a curved needle: an effective technique to create a W-ileal neobladder / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>An important milestone in the area of urinary diversion was the advent of a series of orthotopic bladder substitution (OBS). However, reconstruction of OBS by the traditional hand suture method (THSM) is a time-consuming process. Stapling techniques are considered to be inferior to hand-sewn methods. We report our experience and functional results in patients with W-ileal neobladder by a hand-assisted-drawing-needle running suture (HADNRS).</p><p><b>METHODS</b>Between April 1993 and December 2011, 347 patients (338 men and 9 women) aged 28 - 77 years (median age: 59 years) underwent radical cystectomy, followed by the creation of a modified W-ileal neobladder by HADNRS with a curved needle. A total of 347 (20 patients in 2003) were evaluated by urodynamic tests.</p><p><b>RESULTS</b>The operative time ranged from 110 to 310 minutes (mean 148 minutes), and the mean time of reconstruction by HADNRS, excluding ureterointestinal and ileouretral anastomosis, was (20.2 ± 4.3) minutes. Histopathological analysis of removed specimens showed that 317 patients had transitional cell bladder carcinoma. Of these 317 patients, 19 also had squamous carcinoma and 13 had adenocarcinoma. Glandularis and prostate cancer occurred in 16 and 14 patients, respectively. Three patients (0.8%) had neobladder abdominal fistula. No other early complications or injury to the surgeon's hands occurred due to HADNRS. Of the 20 cases with urodynamic examinations in 2003, two suffered from daytime incontinence and six had nocturnal incontinence. The maximum capacity of the neobladder was (492.9 ± 177.8) ml, and the maximum pressure within the reservoir at the end of filling was (32.1 ± 8.6) cmH2O.</p><p><b>CONCLUSION</b>Reconstruction of W-ileal neobladder by HADNRS is effective and economical.</p>

Efficacy and safety of vardenafil in the treatment of erectile dysfunction: a report of 700 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of long-term on-demand use of vardenafil in the treatment of erectile dysfunction (ED).</p><p><b>METHODS</b>We conducted a questionnaire investigation among 891 ED patients treated by on-demand use of oral vardenafil at 20 mg every 3 days from March 2007 to January 2010, covering the general information of the patients, their need for and attitudes towards the treatment, clinical efficacy and adverse events of the drug, and satisfaction of the patients and their partners after 12 weeks of treatment.</p><p><b>RESULTS</b>Treatment and follow-up were completed in 700 patients, of whom 504 (72%) achieved sufficient hardness and duration of penile erection and overall sexual satisfaction, 84 (12%) admitted to improvement of erectile hardness and duration but not adequate satisfaction, and the other 112 (16%) experienced no significant changes. Significant differences were found in IIEF-5 scores, Rigiscan test results and partners TSS scores before and after the treatment (P < 0.05). Most frequent adverse events included flushing (15%), dizziness and headache (10%), dyspepsia (3%), and nasal congestion (1%).</p><p><b>CONCLUSION</b>Long-term on-demand use of oral vardenafil, in addition to its safety and good tolerance, can effectively improve the erectile function of ED patients, their success rate of sexual intercourse, and overall quality of sexual life.</p>

Replacement of plaque by buccal mucosa in the treatment of Peyronieś disease: a report of 27 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the clinical results of the replacement of plaque by buccal mucosa in the treatment of Peyronie's disease.</p><p><b>METHODS</b>We performed surgical replacement of the plaque by free autograft of buccal mucosa on 27 patients with Peyronie's disease, ranging in age from 24 to 72 years (mean 53), varying in disease course between 1 and 13 years, with a penile curvature angle of 30 degrees - 80 degrees in erection. Of the total number, 15 patients had the plaque located in the dorsal root, 6 in the dorsal shaft, 3 in the subcoronal shaft and 3 in the ventral shaft of the penis; 24 had 1 plaque, 2 had 2 and 1 had 3, ranging in size from 0.7 cm x 0.7 cm to 1.6 cm x 1.0 cm.</p><p><b>RESULTS</b>Satisfactory results were achieved in all the cases, with no such complications as hematoma, infection, oral numbness, and tightness of the mouth. Of the 24 cases that were followed up for 0.5 to 7 years, complete straightening of the penis was achieved in 21, slight residual curvature (< 15 degrees) was noted in 3, a little shortening of the penis (< 1 cm) in 2, and erectile pain in 3.</p><p><b>CONCLUSION</b>Buccal mucosa, with a stable elasticity and no shrinkage, can be recommended for wide use in the surgical treatment of Peyronie's disease.</p>

The rates of conspicuous effectiveness, effectiveness, ineffectiveness and total effectiveness of the combined method were 13.0, 14.5, 72.5 and 27.5% in the injury group, but 55.7, 20.7, 23.6 and 76.4% in the non-injury group, with significant differences (P < 0.05).</p><p><b>CONCLUSION</b>The PDE-5 inhibitor erection-provoking test with audio-visual sexual stimulation is a simple, practical, safe and effective method for the differentiation of organic from psychological erectile dysfunction.</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.

Penile squamous carcinoma in circumcised patients: a report 17 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To discuss the diagnosis and treatment of penile carcinoma in circumcised men.</p><p><b>METHODS</b>We reviewed 17 cases of penile carcinoma detected 1 month to 16 years after circumcision performed in our hospital from January, 1997 to December, 2004.</p><p><b>RESULTS</b>Of the total number, 11 cases were diagnosed as penile carcinoma 1 - 12 months and the others 3 - 16 years after the circumcision. Sixteen of them were treated by partial penectomy, anti 1 first by extensive circumcision and later by partial and total penectomy successively after recurrence. Cloquet nodes biopsy showed 16 cases to be pathologically well-differentiated and I case moderately differentiated penile squamous carcinoma. One died of extensive metastasis, but the other 16 remained disease-free survivals.</p><p><b>CONCLUSION</b>Circumcised adult men, especially those over 40 years of age, are likely to develop penile carcinoma. Patients with inflammation, plaque or ulcer in the prepuce should be checked by pathological biopsy and followed up closely. For Stage-I penile squamous carcinoma, partial penectomy is shown to be an effective therapeutic option, and Cloquet's nodes biopsy is necessary for all patients.</p>

Clinical study of recombinant human growth hormone for male climacteric syndrome / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the effect and safety of the recombinant human growth hormone (rhGH) in the treatment of male climacteric syndrome and to investigate the specificity and sensitivity of insulin-like growth factor-1 (IGF-1) and serum total testosterone as the curative effect index.</p><p><b>METHODS</b>Forty patients aged 40-75 with male climacteric syndrome were divided into two groups randomly and injected with rhGH 4 IU (Group A) or 8 IU (Group B). The patients were followed up for about 12 weeks after 12-week treatment and then asked the questions of the assessed index of male climacteric syndrome at the 4th, 8th and 12th week of the treatment and 12 weeks after the treatment. The serum IGF-1, total testosterone (TT) and prostatic specific antigen(PSA) were measured before and after the treatment. The data were analysed by the software of SPSS 12.0 for Windows.</p><p><b>RESULTS</b>The scores of the 4th, 8th and 12th week and the follow-up significantly declined compared with the baseline (P < 0.01), but did not differ significantly between Groups A and B (P > 0.05). After the treatment, serum total testosterone, PSA and prostate volume had no obvious change (P > 0.05), and the IGF-1 level was markedly higher than the baseline and the normal public. No obvious side effect was found during the treatment and follow-up.</p><p><b>CONCLUSION</b>Small dosage of rhGH(4 IU/week) for 12 weeks can effectively treat male climacteric syndrome. The value of IGF-1 was parallel with the treatment effects. Short-time and small-dosage treatment with rhGH is safe and has little side effect.</p>
