One-layer macroscopic verus two-layer microscopic vasovasostomy: Our experience in two referral hospitals.

OBJECTIVE: Vasovasostomy is the most common surgery to restore the fertility of vasectomized men. This study aimed to compare the outcomes of one-layer macroscopic VV (MOLVV) or two-layer microscopic VV (TLMVV). METHODS: This study was performed on the medical records of 100 patients who underwent VV surgery in two tertiary hospitals from 2014 to 2017. All patient information, including demographic and sperm analysis, was collected. The chi-square test, independent t-test, and survival analysis using Kaplan-Meyer test and Cox regression were performed to analyze the data using SPSS software version 25, and the significance level was considered 0.05. RESULTS: The fertility rate in patients of both groups was 15%. The findings showed a statistically significant difference between the mean percentage of normal sperm morphology according to the type of surgery (p = 0.045). There was no statistically significant difference between the mean sperm count, sperm motility percentage, and mean hospital costs according to the type of surgical procedure (p > 0.05). The incidence of spouse pregnancy in the TLMVV method after 15 and 24 months was 87.5% and 58.3%, respectively. In patients with unilateral anastomosis, the incidence of pregnancy at 13 and 15 months after surgery was 98.7% and 95.8%, respectively. The mean and median time of pregnancy in the spouses of patients with each surgical shower were 24 and 25 months. Other variables had no significant effect on spouse pregnancy. CONCLUSION: Vasovasostomy with the one and two-layer methods had equal results. The number, movement, and normal morphology of sperm after surgery were low. Therefore, these people will need assisted reproductive techniques.

Effect of tamsulosin versus prazosin on clinical and urodynamic parameters in women with voiding difficulty: a randomized clinical trial.

OBJECTIVE: To compare the effects of tamsulosin and prazosin on clinical and urodynamic parameters in women with voiding dysfunction. METHODS: Forty women aged 20-65 years with a clinical diagnosis of voiding dysfunction were blindly randomized to two equal groups for treatment with tamsulosin 0.4 mg or 1-2 mg of prazosin daily. Symptom assessment with the American Urological Association Symptom Score (AUASS) and urodynamic evaluation was performed initially and after three months of treatment. Patient satisfaction was evaluated and severe adverse drug effects recorded. Statistical analysis was carried out using the Student's t-test and Mann-Whitney U test. RESULTS: Although AUASS improved in both groups, the rate of improvement was larger in the tamsulosin group. Urodynamic parameters improved but did not normalize in both groups. Adverse side effects from medication in the prazosin group were more common than in the tamsulosin group. Most of the patients in the tamsulosin group (80%) were satisfied with their treatment compared with those in the prazosin group (45%). CONCLUSION: Tamsulosin and prazosin are both effective in palliating symptoms of women with voiding dysfunction and improving their urodynamic parameters. Tamsulosin may be the preferred drug to prescribe because of its more amenable side effect profile and greater patient satisfaction.
