The role of artery-preserving varicocelectomy in subfertile men with severe oligozoospermia: a randomized controlled study.

BACKGROUND: There is wide agreement nowadays that a clinical varicocoele should be ligated to treat male factor infertility. However, the significance of testicular artery preservation in patients with severe oligozoospermia has not been addressed before. OBJECTIVES: To assess the outcome of varicocelectomy in infertile men with severe oligozoospermia and clinical varicocoeles and to compare internal spermatic artery preservation vs. artery ligation. MATERIALS AND METHODS: This prospective randomized study included 302 infertile patients with severe oligozoospermia and clinical (grade II/III) varicocoeles. Patients were randomized into two groups: group A (150 patients) underwent artery-preserving varicocelectomy (APV) and group B (152 patients) underwent artery-ligating varicocelectomy (ALV). The primary outcome was to assess the changes in sperm density and motility at 3 and 6 months postoperatively in both groups. The secondary outcome was to compare the natural pregnancy rate at 1-year of follow-up. Univariate and multivariate analyses were performed to determine factors affecting pregnancy rate. RESULTS: In both groups, there was a statistically significant improvement in sperm density and motility at 3 and 6 months postoperatively. In group A, there was a greater improvement in sperm density (p < 0.001) and motility (p < 0.001) compared to group B. At 1-year follow-up, overall 35.1% achieved a natural pregnancy. Group A achieved a significantly higher natural pregnancy rate (40% vs. 30%, p value = 0.03) compared to group B. Smaller testicular volume and ALV were the independent predictors of lower pregnancy rate ((HR = 3.2, 95% CI 1.2-8.3, p = 0.01) and (HR = 3.2, 95% CI 1.4-7.1, p = 0.003), respectively). CONCLUSION: In men with severe oligozoospermia and a clinical varicocoele, APV results in improved outcomes as compared to ALV with respect to semen parameters and natural pregnancy rates. Therefore, all attempts should be made to preserve internal spermatic arteries (ISA) during varicocelectomy in men with severe oligozoospermia.

Female sexual dysfunction post radical cystectomy and urinary diversion.

OBJECTIVES: To evaluate the impact of radical cystectomy and urinary diversion on female sexual function. MATERIALS AND METHODS: A Medline search was conducted according to the PRISMA statement for all English full-text articles published between 1980 and 2016 and assessing female sexual function post radical cystectomy and urinary diversion. Eligible studies were subjected to critical analysis and revision. The primary outcomes were the reporting methods for female sexual dysfunction (FSD), manifestations of FSD, and factors associated with FSD, postoperative recoverability of FSD, and awareness level regarding FSD. RESULTS: From the resulting 117 articles, 11 studies were finally included in our systematic review, with a total of 361 women. Loss of sexual desire and orgasm disorders were the most frequently reported (49% and 39%). Dyspareunia and vaginal lubrication disorders were reported in 25% and 9.5%, respectively. The incidence of sexual dysfunction was 10% in 30 patients receiving genital- or nerve-sparing cystectomy vs. 59% receiving conventional cystectomy. CONCLUSION: Although female sexual function is an important predictor of health-related quality of life post radical cystectomy and urinary diversion, the available literature is not enough to provide proper information for surgeons and patients.
