Patients with suboptimal semen parameters following vasectomy reversal represent a diagnostic and therapeutic challenge. This may be caused by either partial or complete anastomotic obstruction. Despite the relatively common clinical use of corticosteroids in this patient population, data remain sparse. Thus, we set out to evaluate the safety and efficacy of prednisone after vasectomy reversal.
A chart review was performed from January 1, 2008 to September 30, 2018 to identify men in which prednisone was used for suspected anastomotic obstruction after vasectomy reversal. Obstruction was based on sub-optimal or decreasing semen parameters and physical exam findings. A course consisted of 2 weeks of 20 mg PO daily followed by 2 weeks of 10 mg PO daily.
A total of 89 patients were identified in which prednisone was used postoperatively. Total motile sperm counts were found to increase in the overall cohort by 10.5 million (p < 0.0002) after a course of prednisone. On sub-group analysis, men who had a bilateral vasovasostomy (VV) or VV/vasoepididymostomy experienced an increase in total motile sperm counts by 13.4 million (p < 0.0012) and 6.2 million (p < 0.014), respectively. Patients who were patent at the time of prednisone treatment were more likely to see an improvement in total motile sperm counts (76.9% versus 33.3%, p < 0.003).
Prednisone seems to be safe and potentially efficacious in men with suspected anastomotic obstruction following vasectomy reversals. Further studies are needed to more conclusively determine the treatment's effectiveness in this patient cohort.
输精管复通术后精液参数不理想的患者存在诊断和治疗方面的挑战。这可能是由于部分或完全吻合口阻塞引起的。尽管皮质类固醇在该患者人群中的临床应用相对常见,但数据仍然很少。因此,我们着手评估泼尼松在输精管复通术后的安全性和疗效。
对 2008 年 1 月 1 日至 2018 年 9 月 30 日的病历进行了回顾性分析,以确定在输精管复通术后因疑似吻合口阻塞而使用泼尼松的男性。阻塞的依据是精液参数不佳或逐渐下降,以及体格检查结果。一个疗程包括 2 周的 20 毫克 PO 每日一次,然后是 2 周的 10 毫克 PO 每日一次。
共确定了 89 例在术后使用泼尼松的患者。在整个队列中,经过一个疗程的泼尼松治疗后,总活动精子计数增加了 1050 万(p<0.0002)。在亚组分析中,行双侧输精管吻合术(VV)或 VV/附睾吻合术的男性总活动精子计数分别增加了 1340 万(p<0.0012)和 620 万(p<0.014)。在接受泼尼松治疗时已经通畅的患者,总活动精子计数更有可能改善(76.9%比 33.3%,p<0.003)。
泼尼松似乎在输精管复通术后疑似吻合口阻塞的男性中是安全且可能有效的。需要进一步的研究来更确定地确定该治疗方法在该患者群体中的疗效。
