Methods: Total testicular volume (right plus left testicular volume) was measured in 794 testes in 397 men with infertility (mean age, 35.6 years) using a Prader orchidometer and also by ultrasonography. Ultrasonographic testicular volumes were calculated as length x width x height x 0.71. To evaluate volume-function relationships, patients were divided into 10 groups representing 5-mL increments of total testicular volume by each method from below 10 mL to 50 mL or more. Results: Mean total testicular volume based on Prader orchidometry and US were 36.8 mL and 26.3 mL, respectively. Semen volume, sperm density, total sperm count, total motile sperm count, and serum FSH, LH, and testosterone all correlated significantly with total testicular volume measured by either method. Mean sperm density was in the oligozoospermic range in patients with total testicular volume below 35 mL by orchidometry or below 20 mL by ultrasonography. Mean total sperm count was subnormal in patients with total testicular volume below 30 mL by orchidometry or under 20 mL by ultrasonography. Conclusion: Testicular volume measured by either ultrasonography or Prader orchidometry correlated significantly with testicular function. However, critical total testicular volume indicating normal or nearly normal testicular function was 30 mL to 35 mL using Prader orchidometer and 20 mL using ultrasonography. Prader orchidometry morphometrically and functionally overestimated the testicular volume in comparison to US. (Asian JAndro12008 Mar; 10: 319-324)展开更多
背景与目的探讨不同部位的肺叶切除术后患者肺容积减少与患者肺功能损害程度的相关性。方法本研究共纳入苏州大学附属第一医院2019年1月-2020年7月行胸腔镜肺叶切除术的131例患者(包括左肺上叶,左肺下叶,右肺上叶,右肺中叶,右肺下叶切除...背景与目的探讨不同部位的肺叶切除术后患者肺容积减少与患者肺功能损害程度的相关性。方法本研究共纳入苏州大学附属第一医院2019年1月-2020年7月行胸腔镜肺叶切除术的131例患者(包括左肺上叶,左肺下叶,右肺上叶,右肺中叶,右肺下叶切除术;其中男性72例,女性59例)。为了比较患者术后肺功能与术前肺功能的差异,分别于术前7天和术后3个月、6个月及1年记录患者的肺功能测量值。采用1秒用力呼气量(forced expiratory volume in 1second,FEV_(1))作为肺功能变化的主要评估参数。采用Mimics Research 19.0软件计算出患者的原始肺容积,各阶段存留的肺容积。分析患者肺容积在上述时间节点与患者肺功能变化的相关性。结果术后患者FEV1较术前降低,下降程度与肺叶的切除体积呈正相关(其中左下肺下降较为明显)。值得注意的是,患者的肺功能降低程度在术后3个月、6个月与1年的差异无统计学意义。结论肺叶切除术后肺组织的容积减少是患者肺功能减少的主要原因,以左肺下叶表现为著,最早可选定术后3个月作为肺叶切除患者残留肺功能的评估节点。展开更多
