Abstract：
This study aims to investigate the association of preoperative body composition parameters, measured by computed tomography in patients undergoing surgery for renal cell carcinoma, with its stage and to survey the relationship with postoperative hospitalization duration and survival.
Demographic data, pathology results, cancer stages, and hospitalization duration of 104 patients undergoing surgery at the urology clinic due to renal cell carcinoma between 2019 and 2023 were analyzed retrospectively. On computed tomography scans acquired during diagnosis, visceral adipose tissue, subcutaneous adipose tissue, total adipose tissue, and skeletal muscle area were measured. The ratios of body composition parameters were computed.
When the correlation between survival time and body composition in deceased patients was analysed, a moderate but significant correlation was observed between skeletal muscle area value and total adipose tissue / skeletal muscle area ratio (r=0.630, p=0.001; r=0.598, p=0.002). A significant and strong correlation was observed between total adipose tissue value and survival (r=0.704, p<0.001). Subcutaneous adipose tissue / skeletal muscle area was found to be an independent risk factor associated with mortality, and a ratio of 0.98 or less increased the mortality risk approximately 16-fold.
The relationship between body composition parameters measured by computed tomography, which can be easily evaluated pre-treatment, and mortality, postoperative recovery and length of hospital stay can be evaluated, giving clinicians an idea about the potential difficulties that patients may encounter during the treatment process. For this purpose, the subcutaneous adipose tissue / skeletal muscle area ratio is the most helpful parameter that can be used..

摘要：
目的：本研究旨在探讨术前身体成分参数的相关性，通过计算机断层扫描在接受肾细胞癌手术的患者中测量，并探讨其分期与术后住院时间和生存率的关系。
方法：人口统计数据，病理结果,癌症阶段，回顾性分析了2019年至2023年因肾癌在泌尿外科诊所接受手术的104例患者的住院时间。在诊断期间获得的计算机断层扫描扫描中，内脏脂肪组织，皮下脂肪组织，总脂肪组织，测量骨骼肌面积。计算身体成分参数的比率。
结果：当分析死亡患者的生存时间与身体成分之间的相关性时，骨骼肌面积值与总脂肪组织/骨骼肌面积比之间存在中等但显著的相关性(r=0.630,p=0.001;r=0.598,p=0.002).在总脂肪组织值和存活率之间观察到显著且强的相关性(r=0.704,p<0.001)。发现皮下脂肪组织/骨骼肌面积是与死亡率相关的独立危险因素。0.98或更低的比率增加了约16倍的死亡风险.
结论：计算机断层扫描测量的身体成分参数之间的关系，这可以很容易地评估预处理，和死亡率，可以评估术后恢复和住院时间，让临床医生了解患者在治疗过程中可能遇到的潜在困难。为此,皮下脂肪组织/骨骼肌面积比是可以使用的最有用的参数。。
