We present a large hydatid cyst located midline and posterior to prostatic gland and seminal vesicles in an asymptomatic patient. Computed tomography (CT) scan revealed a large retrovesical mass and the transrectal ultrasonography idetified a degenerated hydatid cyst with "ball of wool'' appearance. Although extremely rare, hydatid disease should be kept in mind in the differential diagnosis of pelvic particularly retrovesical midline masses.

: We describe our experience in prostate biopsy using a new standardized cognitive fusion techniques, that we call "cognitive zonal fusion biopsy". This new technique is based on two operative options: the first based on target biopsies, the Cognitive Target Biopsy (CTB) if the same target was detected with transrectal ultrasound (TRUS) and multiparametric magnetic resonance (mpMRI); the second based on saturation biopsies, the Zonal Saturation Biopsy (ZSB) on anatomical zone/s containing the region of interest if the same target was not evident with TRUS and MRI...

Chlorhexidine gluconate solution is a potent antimicrobial and therefore could be used effectively for treatment of endometritis, but historically this substance has been implicated as irritating to mucous membranes, including the endometrium of the mare. The use of chlorhexidine hydrochloride suspension (Nolvasan Suspension, Zoetis, Florham Park, NJ, USA) was evaluated in the uterus of normal mares to determine if adverse effects on endometrial health were noted. Twelve healthy, adult light breed mares were included in this study...
