Abstract
The purpose of this paper was to examine whether ultrasound abnormalities of the prostate and seminal vesicles, which may be related to male accessory gland infection, are reproducible. Forty-seven men attending an infertility clinic were studied. Imaging findings of transrectal ultrasonography were recorded. Kappa (κ)-values to determine the intra-and inter-observer variation were assessed. Calcifications have good intra-observer (κ=0.77; 95% CI: 0.59–0.96) and good inter-observer reproducibility (κ=0.73; 95% CI: 0.54–0.93). Dilatation of the peri-prostatic plexus had moderate intra-observer (κ=0.57; 95% CI: 0.33–0.80) and good inter-observer reproducibility (κ=0.74; 95% CI: 0.55–0.94). Other ultrasound abnormalities of the prostate were not reproducible. None of the ultrasound abnormalities of the seminal vesicles were reproducible. In our study the prevalence of ultrasound abnormalities which may be related to male accessory gland infection was as high as 96%. However, only calcifications and dilatation of the venous plexus had good reproducibility. Other observed ultrasound abnormalities of the prostate and seminal vesicles were poorly reproducible and are therefore of no use in the diagnosis of male accessory gland infection.
