Variation of prostatic morphology in Chinese benign prostatic hyperplasia patients of different age decades

Our study aimed to investigate the age-related growth in prostatic morphological parameters in Chinese benign prostatic hyperplasia (BPH) patients, and to find out the regularity of how these parameters change with aging.

Medical records of 1038 BPH patients were obtained from a retrospective database of first-visit men with BPH. Change regularity of prostatic anatomical factors with aging was analyzed.

Patients were classified into four groups according to different age decades. All prostatic anatomical factors assessed in this research increased with age growth (p < .0001). However, these anatomical factors sustained stably when older than 70 years. By analyzing the detailed correlation between age and prostatic morphological parameters, transitional zone index (TZI) (Pearson r = 0.358, r² = 0.128, p < .0001) and transitional zone width (TZW) (Pearson r = 0.344, r ²= 0.118, p < .0001) showed the best correlation coefficient with age. After adjusted the influence of cardiovascular disease (CVD) and diabetes mellitus (DM), the result remained still similarly.

Prostatic morphological parameters increase progressively with age growth when patients were younger than 70 years, indicating reasonable interventions to be provided to BPH patients before 70 years. In addition, TZI and TZW are two practical, easy-to-measure prostatic parameters that are significantly associated with the growth of age compared to others.
