To sonographically investigate whether mountain bikers have a higher prevalence of scrotal abnormalities compared with on-road cyclists.
We studied 85 male mountain bikers (mean age: 25 years; range 17-45 years) and 50 male on-road cyclists (mean age: 23 years, range 15-46 years) with regard to scrotal findings on ultrasound (US).
Medical University Innsbruck, Austria.
Only males who gave a history of extensive mountain biking or on-road bicycling (2 hours or more per day on 6 days a week with a covered distance of more than 5,000 km/year) were entered in our study.
In addition to clinical evaluation, a standard ultrasonographic examination of the scrotum was performed using a linear array transducer operating at a frequency of 8.0 MHz (Acuson Sequoia 512).
The sonographic findings obtained in mountain bikers were compared with those obtained in on-road cyclists.
Eighty of 85 mountain bikers (94%) and 24 of 50 on-road cyclists (48%) presented with abnormal findings on scrotal US. Abnormal US findings in mountain bikers included scrotoliths in 69 bikers (81%), spermatoceles in 39 bikers (46%), and epididymal calcifications in 34 bikers (40%). US findings in on-road cyclists were scrotoliths in 8 cyclists (16%), spermatoceles in 13 cyclists (26%), and epididymal calcifications in 6 cyclists (12%). The overall number of scrotal abnormalities was significantly greater in mountain bikers than in on-road cyclists (P < 0.001).
Mountain bikers compared with on-road cyclists have shown to be at a higher risk for scrotal disorders on US examination. Not only protective measures but also the awareness of the bikers are required to reduce the potential risk. Further studies should be undertaken to determine the clinical significance of the sonographic changes.
通过超声检查探究山地自行车骑行者与公路自行车骑行者相比，阴囊异常的患病率是否更高。
我们研究了85名男性山地自行车骑行者（平均年龄：25岁；范围17 - 45岁）和50名男性公路自行车骑行者（平均年龄：23岁，范围15 - 46岁）的阴囊超声检查结果。
奥地利因斯布鲁克医科大学。
仅纳入有大量山地自行车骑行或公路自行车骑行史的男性（每周6天，每天骑行2小时或更长时间，每年骑行距离超过5000公里）。
除临床评估外，使用频率为8.0 MHz的线性阵列换能器（Acuson Sequoia 512）对阴囊进行标准超声检查。
比较山地自行车骑行者与公路自行车骑行者的超声检查结果。
85名山地自行车骑行者中有80名（94%）阴囊超声检查有异常发现，50名公路自行车骑行者中有24名（48%）有异常发现。山地自行车骑行者的超声异常发现包括69名骑行者（81%）有阴囊结石，39名骑行者（46%）有精液囊肿，34名骑行者（40%）有附睾钙化。公路自行车骑行者的超声发现为8名骑行者（16%）有阴囊结石，13名骑行者（26%）有精液囊肿，6名骑行者（12%）有附睾钙化。山地自行车骑行者阴囊异常的总数明显多于公路自行车骑行者（P < 0.001）。
超声检查显示，与公路自行车骑行者相比，山地自行车骑行者患阴囊疾病的风险更高。需要采取保护措施并提高骑行者的意识以降低潜在风险。应进一步开展研究以确定超声变化的临床意义。
