Ultrasound anatomy of the normal male reproductive tract

Abstract

Ultrasound is being used with increasing frequency in the evaluation of the male reproductive tract. To detect abnormalities, it is important to have a comprehensive understanding of the normal anatomy and normal variations. In this article, the ultrasound anatomy of the scrotum, penis, prostate, and seminal vesicles is presented. Because ultrasound is a very visual process, the anatomy is presented not only with text, but also through the liberal use of ultrasound images and associated diagrams. Ultrasound is both an operator‐ and equipment‐dependent procedure and, where appropriate, we have included technical discussions regarding ultrasound equipment and settings. © 1996 John Wiley & Sons, Inc.

Ultrasound of the male genital tract in relation to male reproductive health

Seminal vesicles ultrasound features in a cohort of infertility patients

“…The prostate-vesicular region was assessed at rectal ultrasonography through transverse, longitudinal (Behre et al, 1995;Vicari, 1999) and oblique scans with patients placed in the left lateral decubitus (Lotti et al, 2011a,b). Two different probes were used, a transrectal biplanar probe (linear transducer U533L 7.5 MHz; convex transducer U533C 6.5 MHz), more sensitive for the detection of prostatic features and an 'end fire' probe (V53W 6.5 MHz, field of view 50 -2008) in order to better investigate SV, according to previous studies (Older and Watson, 1996;Lotti et al, 2011a,b). Prostate volume was measured using the planimetric method as previously reported (Behre et al, 1995;Vicari, 1999;Lotti et al, 2011a,b).…”

Zero-order controlled release of ciprofloxacin-HCl from a reservoir-based, bioresorbable and elastomeric device

“…A proposed version of the device for this application, containing 8.0 - 8.5 mg of CIP, could be 2.5 cm in length with 500-μm thick walls, a 450-μm diameter drug rod and a single 100-μm diameter orifice. This device would fit within a 14 gauge (1.6 mm inner diameter) transrectal needle for injection into the torturous inner tubule of the seminal vesicle (2-6 mm in diameter in the normal male) [40]. Using the direct relationships of release rate ( dM/dt ) with wall thickness ( h) and length (proportional to A ) from Eq.…”
