Abstract

Background: This study aims to assess the relationship between body mass index (BMI) and prostate volume, utilizing pre and postoperative measurements.

Methods: 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).

Results: 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, R² = 0.026 (p = 0.036) for DRE, R² = 0.076 (p < 0.0001) for TRUS, R² = 0.038 (p = 0.011) for MRI and R² = 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.

Conclusions: This study demonstrates a positive linear correlation between BMI and prostate volume, highlighting the importance of considering BMI in prostate volume assessments.

体重指数与前列腺体积的相关性：前列腺癌患者术前和术后测量的回顾性分析。

背景：本研究旨在评估身体质量指数（BMI）和前列腺体积之间的关系，利用术前和术后测量。方法：采用来自机构数据库的数据，在单个地点进行回顾性观察性研究。回顾了接受机器人辅助根治性前列腺切除术的患者的医疗记录。数据包括年龄、BMI和通过直肠指检（DRE）、经直肠超声（TRUS）、磁共振成像（MRI）和手术标本重量（SPW）测量的前列腺体积。结果：共发现168例患者并纳入分析。Spearman相关检验显示BMI与前列腺体积在所有测量方法中均有显著相关性，DRE的r = 0.146 (p = 0.047)， DRE的r = 0.268 (p = 0.026 (p = 0.036)， MRI的R2 = 0.076 (p 2 = 0.038 (p = 0.011)， SPW的R2 = 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，每增加BMI，预测前列腺体积增加0.865gr。结论：本研究表明BMI与前列腺体积呈线性正相关，强调了在评估前列腺体积时考虑BMI的重要性。
