High Concentration of Reticular Fibers in Periurethral Region of the Prostatic Urethra from Patients with Benign Prostatic Hyperplasia as Revealed by Stereology

The goal of this investigation was to analyze and quantify changes of the reticular fibers in the prostatic urethra of patients with benign prostatic hyperplasia (BPH) and compare with a control group. Prostatic urethra tissue samples were obtained from ten patients (age range 65 to 79 years, mean 6...
