[Histological characteristics of the prostate in men who receive re-TURP for benign prostatic hyperplasia and their clinical significance].

Objective: To investigate the pathohistological characteristics of the prostate tissues in patients who receive a second TURP and to evaluate their clinical significance.

Methods: We collected surgical specimens from 50 cases of TURP (the control group) and another 50 cases of re-TURP (the re-TURP group), detected the expressions of CD34, vascular endothelial growth factor (VEGF) and androgen receptor (AR) in the prostate tissues by immunohistochemistry (S-P), and determined microvessel density (MVD) and the expressions of VEGF and AR. We performed statistical analyses on the results obtained from the specimens of the control group as well as from those of the first and second operations of the re-TURP group.
