This study aims to assess the relationship between body mass index (BMI) and prostate volume, utilizing pre and postoperative measurements.
A retrospective, observational study was conducted at a single site using data from an institutional database. Medical records of patients who underwent robot-assisted radical prostatectomy were reviewed. Data included age, BMI, and prostate volumes measured through digital rectal exam (DRE), transrectal ultrasound (TRUS), magnetic resonance imaging (MRI), and surgical specimen weight (SPW).
A total of 168 patients were identified and included in the analysis. Spearman's correlation test revealed a significant association between BMI and prostate volume for all measurement methods, reporting r = 0.146 (p = 0.047) for DRE, r = 0.268 (p < 0.0001) for TRUS, r = 0.177 (p = 0.021) for MRI and r = 0.234 (p = 0.002) for SPW. Linear regression analysis confirmed the significant association between BMI and prostate volume, reporting, respectively, R = 0.026 (p = 0.036) for DRE, R = 0.076 (p < 0.0001) for TRUS, R = 0.038 (p = 0.011) for MRI and R = 0.040 (p = 0.009) for SPW. Notably, considering the SPW the best way to estimate prostate volume, for every increase in BMI, the predicted increase of prostate volume is 0.865gr.
This study demonstrates a positive linear correlation between BMI and prostate volume, highlighting the importance of considering BMI in prostate volume assessments.
本研究旨在利用术前和术后测量数据评估体重指数（BMI）与前列腺体积之间的关系。
在单一研究点进行了一项回顾性观察研究，使用机构数据库中的数据。对接受机器人辅助根治性前列腺切除术的患者的病历进行了回顾。数据包括年龄、BMI以及通过直肠指检（DRE）、经直肠超声（TRUS）、磁共振成像（MRI）测量的前列腺体积和手术标本重量（SPW）。
共识别出168例患者并纳入分析。Spearman相关性检验显示，对于所有测量方法，BMI与前列腺体积之间均存在显著关联，DRE的r = 0.146（p = 0.047），TRUS的r = 0.268（p < 0.0001），MRI的r = 0.177（p = 0.021），SPW的r = 0.234（p = 0.002）。线性回归分析证实了BMI与前列腺体积之间的显著关联，DRE的R = 0.026（p = 0.036），TRUS的R = 0.076（p < 0.0001），MRI的R = 0.038（p = 0.011），SPW的R = 0.040（p = 0.009）。值得注意的是，考虑到SPW是估计前列腺体积的最佳方法，BMI每增加一个单位，前列腺体积的预测增加量为0.865克。
本研究表明BMI与前列腺体积之间存在正线性相关性，突出了在前列腺体积评估中考虑BMI的重要性。
