ABSTRACT
The aim of this work was to detect the role of transrectal prostatic biopsy and the use of different stains in the diagnosis of chronic trichomonas prostatitis. Trichomoniasis vaginalis was diagnosed in 28% of 100 male patients with urethritis. The diagnosis was based on the detection of Trichomonas vaginalis trophozoites in urethral discharge by wet mount and Giemsa positive stain which was seen in 28 cases, while trophozoites were detected in the sediments of centrifuged urine of only 21 cases. Among 28 trichomonas positive urethritis patients, 14 cases were diagnosed clinically as chronic prostatitis. The histopathology in ten cases confirmed the diagnosis of trichomonas chronic prostatitis by demonstrating Trichomonas vaginalis trophozoites in the prostatic biopsies stained with both modified periodic acid Schiff and Giemsa stains. All patients were cured both clinically and parasitologically after treating them and their parents with metronidazol. In conclusion, better results were obtained by the use of easy available and cheap stains for the detection and identification of T. vaginalis in prostatic biopsies
