Abstract

BACKGROUND: One type of thalassemia known as transfusion-dependent thalassemia (TDT) requires a lifelong blood transfusion. Iron overload from prolonged blood transfusions causes nutritional disorders and several organs impairment, including the testicles. In contrast to an orchidometer, ultrasound shows more details of the testicles. This study aimed to compare testicular volumes based on ultrasound and orchidometer measurements and correlate testicular volume with nutritional status in TDT patients.METHODS: A cross-sectional study including 27 male thalassemia subjects who underwent routine check-ups was conducted. Measurements of testicular volume using an orchidometer and ultrasound, and body mass index (BMI) was performed. Ultrasound measurement of testicular volume was calculated using the Lambert Formula, while the orchidometer was performed by matching the bead next to the testicle.RESULTS: Most subjects were underweight (63%) or normal weight (37%). However, no significant correlation between BMI and testicular volume was found. As measured using an orchidometer, the mean volume of the right and left testes were 9.22±4.92 mL and 8.67±4.45 mL, respectively. Ultrasound measurement showed the mean values of the right and left testicles were 7.68±3.96 mL and 7.09±4.03 mL, respectively. Testicular measurements obtained using ultrasound showed a significant difference (p<0.05) when compared with the orchidometer. The testicle measured by ultrasound was smaller, which was more accurate. However, the comparison between the right and the left testicular volumes showed no significance.CONCLUSION: Thalassemia patients are mainly underweight, and their nutritional status have no relationship with testicular volume. Ultrasound, as compared to an orchidometer, is better for measuring testicular volume.KEYWORDS: thalassemia, testicle, orchidometer, ultrasound, body mass index

输注依赖型地中海贫血超声与睾丸体积测量的比较及其与营养状况的关系

背景:输血依赖型地中海贫血(TDT)需要终生输血。长期输血造成的铁超载会导致营养失调和几个器官受损，包括睾丸。与睾丸测量仪相比，超声波能显示睾丸的更多细节。本研究旨在比较基于超声和睾丸仪测量的睾丸体积，并将睾丸体积与TDT患者的营养状况联系起来。方法:对27例接受常规检查的男性地中海贫血患者进行横断面研究。使用睾丸仪和超声测量睾丸体积，并进行体重指数(BMI)测量。超声测量睾丸体积采用兰伯特公式计算，而睾丸仪通过匹配睾丸旁边的头来进行。结果:大多数受试者体重过轻(63%)或体重正常(37%)。然而，BMI和睾丸体积之间没有明显的相关性。用兰氏仪测得左右睾丸平均体积分别为9.22±4.92 mL和8.67±4.45 mL。超声测量显示左右睾丸平均值分别为7.68±3.96 mL和7.09±4.03 mL。超声睾丸测量结果与睾丸仪比较，差异有统计学意义(p<0.05)。超声测量的睾丸更小，更准确。而左右睾丸体积比较无统计学意义。结论:地中海贫血患者以体重过轻为主，其营养状况与睾丸体积无关。相比于睾丸计，超声波更适合测量睾丸体积。关键词:地中海贫血，睾丸，睾丸仪，超声，体重指数
