Laparoscopy-assisted pelvi-scrotal vasovasostomy.

Iatrogenic obstruction of the vas deferens within the inguinal canal can be managed by direct on-site vasovasostomy. However, in cases with large defect of the vas, the anastomosis may be under tension. Dissecting through the site of a previous hernia repair is tedious, and may lead to recurrence of the hernia. The present work reports an, first of a kind, alternative technique that avoids the latter drawbacks. Fifteen cases were operated upon. Under laparoscopic vision, the pelvic vas was dissected and the lateral-most end was clipped, cut and extruded from the abdomen through a port in the external inguinal ring. End-to-end vasovasostomy and microsurgical anastomosis for the vasal vessels were performed, bridging the retrieved stump of the pelvic vas with the scrotal vas. There were positive results in the form of sperm count ranging from 1.5 to 15 million ml(-1), an average of 7.25 (SD 5.44) in nine of 15 cases (60%), within the first 6 months following surgery. "Pelvi-scrotal vasovasostomy" can be offered as a cost-effective and successful alternative or supplement to intracytoplasmic sperm injection, for cases with iatrogenic large defects of the vas deferens within the inguinal canal.

Prevalence of erectile dysfunction and its correlates among men attending primary care clinics in three countries: Pakistan, Egypt, and Nigeria.

The prevalence and correlates of erectile dysfunction (ED) in developing countries are largely unknown. Our objectives were to determine the prevalence and associated factors of ED in three countries (Pakistan, Egypt, Nigeria) that represent very different cultures. Men 35-70y of age seeking primary medical care answered a structured questionnaire adapted to reflect local cultures. Degree of ED was categorized as 'none,' 'mild,' 'moderate,' or 'complete.' The age-adjusted prevalence rates of ED among men attending primary care clinics was 57.4% in Nigeria, 63.6% in Egypt, and 80.8% in Pakistan. Older age, diabetes, peptic ulcers, prostate disease, depression-related symptoms, and caffeine consumption were independently associated with increased prevalence of ED, whereas being moderately active to very active at work (hard physical labor) and during leisure time (strenuous exercise) was associated with half the prevalence of moderate-to-complete ED. Our multicultural study demonstrates that in every country studied, high proportions of men older than age 35 have some degree of ED (57-81%). Both severity and prevalence increase consistently with age. Factors associated with ED are similar, but their distribution differs across countries.

Efficacy and safety of sildenafil citrate (Viagra) for the treatment of erectile dysfunction in men in Egypt and South Africa.

The efficacy of sildenafil citrate (Viagra), an oral agent for the treatment of erectile dysfunction (ED), has been demonstrated in global studies. This 12-week randomized, double-blind, placebo-controlled, parallel-group, flexible-dose study assessed the efficacy and safety of sildenafil to treat ED in men in Egypt and South Africa. Men with ED of varied etiology were randomized to receive sildenafil 50 mg (n=128) or placebo (n=126); doses could be adjusted to 100 or 25 mg. Questions from the International Index of Erectile Function (IIEF) assessing the ability to achieve (Q3) and maintain (Q4) erections demonstrated a significant improvement with sildenafil compared with placebo (P<0.0001). Improved erections were reported by 74% of patients receiving sildenafil and 27% of those receiving placebo (P<0.0001). Headache, dyspepsia, and flushing were the most common adverse events in sildenafil-treated patients. These results are consistent with clinical trials in other countries. We conclude that sildenafil is an efficacious and well-tolerated treatment for men with ED in Egypt and South Africa.
