Abstract

Objective To explore the effect of benign prostatic hyperplasia on the thicknesses of different parts of the bladder wall using three-dimensional measurement and analysis methods. Methods 110 patients visited Jinhua People's Hospital due to lower urinary tract symptoms were collected retrospectively. According to strict inclusion and exclusion criterion, 60 patients were identified as a research object. Three-dimensional models of bladder and prostate were constructed based on the T2 weighted magnetic resonance images of these patients. The prostate volume and bladder wall thicknesses were analyzed in different parts in three-dimensional level. Results For patients with benign prostatic hyperplasia, the upper right and left bladder wall thicknesses were (4.47±0.81) mm and (3.90±1.03) mm, respectively. The lower right and left bladder wall thicknesses were (4.92±0.96) mm and (4.45±1.00) mm, respectively. The lower right and left bladder wall thicknesses were significantly greater than the upper right and left, respectively (P=0.006 and 0.003, respectively). Lower left bladder wall thicknesses in aged over 60 group was significantly greater than that in aged under 60 group (P=0.001). Lower right bladder wall thicknesses in prostate volume >60 ml group was significantly greater than that in prostate volume<60 ml group (P=0.008). Lower right bladder wall thicknesses increased significantly with the increase of international prostate symptom score. Conclusions Through quantitative analysis of the three-dimensional measurement of male bladder anatomical parameters, it can provide reference for treatment and diagnostics of prostatic hyperplasia.
