Effects of micronised purified flavonoid fraction on pain, semen analysis and scrotal color Doppler parameters in patients with painful varicocele; results of a randomized placebo-controlled study
ABSTRACT Aim of this study is to evaluate the effects of micronised purified flavonoid fraction (Daflon(®)) on pain, semen analysis and color Doppler parameters in patients with painful varicocele.
Forty varicocele patients whom have normal sperm concentration (>20 million/ml) were involved in the study. The patients were divided into two groups such as Daflon (n = 20) and placebo (n = 20) group. Pain score, semen analyses and Doppler sonography were performed in all patients before and after the treatment.
In the first group, mean pain scores at 1, 3, 6 and 12 months were 1.80 ± 1.32, 1.15 ± 0.93, 1.05 ± 0.95 and 0.95 ± 0.89, respectively, all were significantly lower (P < 0.001 for each) than baseline (5.25 ± 1.07). While semen volume, total sperm count, sperm concentration and morphology were not changed significantly, the motility of sperm increased significantly (P = 0.015) due to decrease in grade 1 sperms at the 6th month in the first group. Reflux time of left spermatic vein during the Valsalva maneuver decreased significantly (P < 0.001).
Results of this study suggest the safety and efficacy of Daflon in the treatment of varicocele-associated pain. However, these results of the present study must be confirmed by randomized placebo-controlled studies by using different drug doses and durations before making any recommendation for the use of Daflon.

ABSTRACT: Varicocele, the leading cause of male infertility, can impair spermatogenesis through several pathophysiological mechanisms. Of these, current evidence suggests that oxidative stress is the central element contributing to infertility in men with varicocele, to which the testis responds by way of heat stress, ischaemia or production of vasodilators, such as nitric oxide. Surgical varicocele repair (varicocelectomy) is beneficial not only for alleviating oxidative stress-associated infertility, but also for preventing and protecting against the progressive character of varicocele and its consequent upregulations of systemic oxidative stress. However, antioxidant therapy in infertile men with surgically treated and those with untreated varicocele is poorly studied, and well-designed trials are needed.Nature Reviews Urology 11/2012; DOI:10.1038/nrurol.2012.198 · 4.52 Impact Factor

ABSTRACT: Background and Objectives: To evaluate the usefulness of laparoscopic varicocelectomy in the management of chronic scrotal pain. Methods: Between 2009 and 2011, 48 patients in total were treated with laparoscopic varicocelectomy for dull scrotal pain that worsened with physical activity and was attributed to varicoceles. All patients were followed up at 3 and 6 months and biannually thereafter with a physical examination, visual analog scale score, and ultrasonographic scan in selected cases. Results: The mean age was 38.2 years (range, 23-54 years). The mean follow-up period was 19.6 months (range, 6-26 months). Bilateral varicoceles were present in 7 patients (14.6%), and a unilateral varicocele was present in 41 (85.4%). The varicocele was grade 3 in 27 patients (56.3%), grade 2 in 20 (41.6%), and grade 1 in 1 (2.1%). The mean preoperative visual analog scale score was 4.8 on a scale from 0 to 10. The mean postoperative visual analog scale score at 3 months was 0.8. After the procedure, 42 patients (87.5%) had a significant improvement in the visual analog scale score (P < .001); 5 (10.4%) had symptom improvement, although it was not statistically significant; and 1 (2.1%) remained unchanged. During follow-up, we observed 5 recurrences (10.4%) whereas de novo hydrocele formation was identified in 4 individuals (8.3%). Conclusion: Laparoscopic varicocelectomy is efficient in the treatment of symptomatic varicoceles with a low complication rate. However, careful patient selection is necessary because it appears that individuals presenting with sharp, radiating testicular pain and/or a low-grade varicocele are less likely to benefit from this procedure.JSLS: Journal of the Society of Laparoendoscopic Surgeons / Society of Laparoendoscopic Surgeons 07/2014; 18(3).
