Penoplasty with T-shaped incision and three-point fixation for concealed penis / 中华男科学杂志

<p><b>Objective</b>To search for a safe and effective method of penoplasty with low incidence of complications for concealed penis by evaluating penoplasty with T-shaped incision and three-point fixation in comparison with modified Devine's technique.</p><p><b>METHODS</b>We retrospectively analyzed 169 cases of concealed penis treated in our center by penoplasty with T-shaped incision and three-point fixation (group A, n = 110) or modified Devine's surgery (group B, n = 59). We compared the operation time, postoperative complications, and recurrence rate between the two groups of patients.</p><p><b>RESULTS</b>Operations were successfully completed in all the cases, the urinary catheters removed at 3 days and the elastic bandages applied for 2 to 4 weeks. The patients were followed up for 4 to 12 months. The penis was satisfactorily exposed. The operative time was significantly shorter in group A than in B (［52.8 ± 6.9］ vs ［61.5 ± 10.6］ min, P < 0.001), the postoperative complication rate was obviously lower in the former than in the latter (prepuce edema: 17.27% ［19/110］ vs 33.89% ［20/59］, P = 0.021; bleeding: 0.90% ［1/110］ vs 3.38% ［2/59］, P = 0.552; skin necrosis: 0.90% ［1/110］ vs 5.08% ［3/59］, P = 0.123; skin infection: 0.90% ［1/110］ vs 5.08% ［3/59］, P = 0.123), and so was the recurrence rate (0.90% ［1/110］ vs 6.77% ［4/59］, P = 0.032).</p><p><b>CONCLUSIONS</b>Penoplasty with T-shaped incision and three-point fixation deserves to be popularized clinically for its advantages of minor invasion, clear exposure, reliable penile fixation, low incidence of postoperative complications and recurrence, and satisfactory outcomes.</p>

Etiological factors for calculus-associated seminal vesiculitis: Analysis of calculus composition in 6 cases / 中华男科学杂志

Objective@#To explore the etiological factors for calculus-associated seminal vesiculitis by analyzing the composition of seminal vesicle calculus samples.@*METHODS@#This retrospective study included 6 cases of recurrent hematospermia diagnosed with seminal vesicle calculus by non-contrast pelvic CT. The patients were aged 28 to 69 years, with persistent or recurrent hematospermia for 3 months to 6 years, and 5 of them with a history of acute urethritis. All the patients underwent seminal vesiculoscopy, which confirmed calculus-associated seminal vesiculitis. The calculus samples were obtained with a spiral dislodge and their composition was determined with a second-generation infrared calculus composition analyzer. The patients were followed up for 2 to 12 weeks postoperatively, during which non-contrast pelvic CT was employed for observation of recurrent calculus in the reproductive tract.@*RESULTS@#Pelvic CT scanning indicated recurrence of seminal vesicle calculus in 3 cases at 12 weeks postoperatively, of which, 2 were accompanied with recurrent hematospermia, both observed at 4 weeks after operation. As for the composition of the calculus, the infrared calculus composition analyzer revealed struvite (magnesium ammonium phosphate hexahydrate) in 5 cases and a mixture of calcium oxalate dihydrate, calcium oxalate monohydrate, and carbonate apatite in the other one.@*CONCLUSIONS@#Seminal vesicle calculi are most commonly composed of struvite, and infection is the main etiological factor for calculus-associated seminal vesiculitis.

Application value of Toshiba 320-row dynamic volumetric CT angiography in the diagnosis of venous erectile dysfunction / 中华男科学杂志

<p><b>Objective</b>To investigate the application value of Toshiba 320-row dynamic volumetric CT angiography in the diagnosis of venous erectile dysfunction (VED).</p><p><b>METHODS</b>We enrolled in this study 33 patients diagnosed with ED by audiovisual sexual stimulation screening in the outpatient department. Penile erection was induced in the patients by injection of 2 mg phentolamine plus 30 mg papaverine into the corpus cavernosum, followed by that of contrast agent of iobitridol through the vein and corpus cavernosum successively. Then 320-row dynamic volumetric CT angiography was performed and the images of the corpus cavernosum in the arterial and venous phases were collected and processed.</p><p><b>RESULTS</b>Different degrees of abnormal venous drainage were observed in 29 of the patients, including 7 cases (24.1%) of back deep venous leakage, 6 cases (20.7%) of foot venous leakage, 3 cases (10.3%) of dorsal superficial venous leakage, 1 case (3.5%) of intervertebral venous leakage, 2 cases (6.9%) of cavernous venous leakage, and 10 cases (34.5%) of mixed venous leakage. Ten of the patients underwent surgery, dorsal deep penile vein ligation in 2 cases, dorsal deep vein embedding plus foot vein ligation in 4, and foot vein ligation in the other 4. Eight of the patients were followed up for 3－12 months post-operatively, during which 2 achieved obvious erectile improvement, while the other 6 gained normal penile erection.</p><p><b>CONCLUSIONS</b>Toshiba 320-row dynamic volumetric CT angiography is a reliable method for the diagnosis of VED, which displays the precise location of venous leakage for clinical treatment, with the advantages of clearer images, lower doses of contrast agent and radiation, and faster examination than X-ray penile angiography.</p>

Benefit of network education to college students' knowledge about sexual and reproductive health in Ningbo city / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.</p><p><b>METHODS</b>From December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.</p><p><b>RESULTS</b>A total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.</p><p><b>CONCLUSION</b>Network education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.</p>

Sexual function and mental state in patients with redundant prepuce or phimosis / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the correlation of sexual dysfunction with psychological abnormalities by analyzing the sexual function and mental state of the patients with redundant prepuce or phimosis.</p><p><b>METHODS</b>This study included 216 randomly selected patients with redundant prepuce or phimosis and 85 normal male controls. We conducted investigations among the subjects using a questionnaire on the general data of the patients, Chinese Index of Sexual Function for Premature Ejaculation (CIPE), International Index of Erectile Function (IIEF), and Symptom Checklist 90 (SCL-90). Then we assessed the status of premature ejaculation (PE) and erectile dysfunction (ED), calculated the incidence of psychological abnormalities, such as depression and anxiety, and analyzed the correlation of PE and ED with the mental state of the patients.</p><p><b>RESULTS</b>The PE and ED patients scored significantly higher than normal controls on SCL-90, somatization, compulsion, depression, anxiety and other factors (P < 0.05). CIPE scores were correlated with the scores on SCL-90, somatization, compulsion, interpersonal sensitivity, depression, anxiety and other factors, while ED-related scores showed no correlation with the scores on SCL-90 and other factors.</p><p><b>CONCLUSION</b>Patients with redundant prepuce or phimosis have poor mental health, and there is an interaction between PE and the mental state of the patient.</p>

Clinical application of a new device for minimally invasive circumcision / 亚洲男科学杂志(英文版)

<p><b>AIM</b>To study the clinical effects of a disposable circumcision device in treatment of male patients of different ages with either phimosis or excess foreskin.</p><p><b>METHODS</b>One thousand two hundred patients between the age of 5 and 95 years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007. Of these cases, 904 had excess foreskin and 296 were cases of phimosis.</p><p><b>RESULTS</b>In 96.33% of the cases the incision healed, leaving a minimal amount of the inner foreskin with no scarring and producing good cosmetic results. There were no incidents of device dislocation or damage to the frenulum. The average operative time was 2.5 min for excess foreskin, and 3.5 min for phimosis. During the 7 days of wearing the device, mild to moderate edema occurred in 10.08% of cases with excess foreskin and in 2.58% of those with phimosis. Edema in the frenulum was seen in 1.67% of patients, and only 0.67% had an infection of the incision. A total of 86.25% of patients reported pain due to penile erection. After removal of the device, 0.58% of the cases had minimal bleeding around the incision, and 2.42% had wound dehiscence.</p><p><b>CONCLUSION</b>The new device can be applied to an overwhelming majority of patients with phimosis and excess foreskin. This technique is relatively simple to perform, and patients who underwent this surgery had very few complications. Antibiotics were not required and patients reported less pain than those who were circumcised using conventional methods. Circumcision with this device requires minimal tissue manipulation, and is quicker and safer than circumcision using conventional techniques.</p>
