BACKGROUND: The aim of this study was to evaluate the incidence of prostatic calcification and prostatitis NIH category IV in patients with obstructive BPH.
METHODS: Ninety-six patients with obstructive BPH who had undergone transurethral electroresection of the prostate gland were evaluated. In accordance with a preoperative transrectal ultrasound examination, patients were divided into one group with prostatic calcification (N.=31) and one without (N.=65). Prostatitis NIH category IV was classified according to the grading system by Irani. Correlations between the incidence of prostatic calcification, histological prostatitis, PSA, uric acid, cholesterol, triglycerides, CRP, IPSS, IIEF-25, and NIC-CPSI were analyzed. A stone analysis of prostatic calcification was performed using X-ray powder diffraction.
RESULTS: Sixty-nine (71.9%) patients had NIH category IV prostatitis, accounting for 83.9% of those with prostatic calcification versus 66.1% of those without (P<0.04). Significant correlations were found between prostatic calcification and the severity of inflammation (P<0.02) as well as the NIH-CPSI subdomain of urinary symptoms (P<0.02). The only predictor for prostatic calcifications were elevated levels of uric acid. Such patients were 1.4times more likely of having calcifications in the prostate gland (OR=1.4, P<0.047). Stone analysis revealed the following: apatite in 41.7%, whewellite in 29.2%, weddellite and brushite in 8.7% each, whitlockite, apatite/whewellite and organic substances in 4.2%.
CONCLUSIONS: On ultrasound examination, one third of patients who were treated with TURP for obstructive BPH had prostatic calcification. These were significantly more common in patients with NIH category IV prostatitis.
