The Effect of Chronic Prostatic Inflammation on Acute Urinary Retention in the Setting of Benign Prostatic Hyperplasia / 대한비뇨기과학회지

ABSTRACT

PURPOSE: The aim of this study was to evaluate the effect of chronic prostatic inflammation on acute urinary retention(AUR) in the setting of benign prostatic hyperplasia(BPH). MATERIALS AND METHODS: A total of 132 male patients admitted to our clinic with BPH-related AUR or BPH-related lower urinary tract symptoms (LUTS) were included in this study. These patients were divided into two groups. Group 1 consisted of 58 patients with AUR who underwent transurethral resection of the prostate(TURP), and group 2 consisted of 74 patients with LUTS who underwent TURP. Prostatic infarction, morphology, inflammation were examined. Prostatic infarction was evaluated according to the presence or absence of infarction. Prostatic morphology was assessed according to three categories mainly glandular hyperplasia, stromal hyperplasia, or a mixture of glandular and stromal hyperplasia. Prostatic inflammation was assessed according to three categories mild, moderate, and severe. RESULTS: Prostatic infarction was observed in 8.6% of the patients in group 1 and in 8.1% of the patients in group 2(p=1.000). Glandular, stromal, and mixed hyperplasia were detected in 36.2%, 5.2%, and 58.6% of the patients in group 1 and in 35.1%, 6.8%, and 58.1% of the patients in group 2, respectively(p=0.222). Mild, moderate, and severe chronic prostatic inflammation were observed in 39.7%, 31.0%, and 29.3% of the patients in group 1 and in 73.0%, 20.3%, and 6.7% of the patients in group 2, respectively(p<0.001). CONCLULSIONS Chronic prostatic inflammation may play an important role on AUR developing secondary to BPH.
