is varicocele associated with underlying Venous abnormalities varicocele and the Prostatic Venous Plexus
2008Co-Authors: Hideo Sakamoto, Yoshio OgawaAbstract:Purpose: We examined the pampiniform Plexus and Prostatic Venous Plexus using color Doppler ultrasonography and evaluated the relationship between varicocele and the Prostatic Venous Plexus.Materials and Methods: This study included 209 men with a mean age of 35.3 years, of whom 68 had no varicoceles, 94 had a unilateral varicocele and 47 had bilateral varicoceles based on scrotal color Doppler ultrasonography. The diameter of the pampiniform Plexus and Prostatic Venous Plexus was measured using scrotal and transperineal ultrasonography, respectively. Peak retrograde and antegrade flow velocity of the Prostatic Venous Plexus was measured by transperineal color Doppler ultrasonography.Results: Mean diameter, and peak and antegrade flow velocity of the Prostatic Venous Plexus were greater in men with bilateral varicoceles than in those with a unilateral varicocele and in those without a varicocele (p <0.01). Moreover, men with a unilateral varicocele had a greater mean peak antegrade flow velocity than thos...

male accessory gland infection frequency in infertile patients with chronic microbial prostatitis and irritable bowel syndrome transrectal ultrasound examination helps to understand the links
2012Co-Authors: Enzo Vicari, Aldo E. Calogero, Rosita A. Condorelli, Lucia O Vicari, Sandro La VigneraAbstract:The aim of this study was to evaluate the frequency of male accessory gland infection (MAGI) in patients with chronic bacterial prostatitis (CBP) plus irritable bowel syndrome (IBS) and to compare the sperm parameters of patients with or without MAGI. In addition, another objective of this study was to evaluate the ultrasound characterization of the anatomical space between the posterior wall of the prostate and the anterior wall of the rectum using transrectal ultrasonography. Fifty consecutive patients with the following criteria were enrolled: 1) infertility, 2) diagnosis of CBP, and 3) diagnosis of IBS according to the Rome III criteria. The following 2 age-matched control groups were also studied: infertile patients with CBP alone (n 5 56) and fertile men (n 5 30) who had fathered a child within the previous 3 months. Patients and controls underwent an accurate patient history; administration of the National Institutes of Health-Chronic Prostatitis Symptom Index and the Rome III questionnaires for prostatitis and IBS, respectively; physical examination; semen analysis; and transrectal ultrasound evaluation (limited to patients with CBP and IBS or CBP alone). A significantly higher frequency of MAGI was found in patients with CBP plus IBS (82.0%) compared with patients with CBP alone (53.6%) or fertile men (0%). The presence of MAGI in patients with CBP plus IBS was associated with a significantly lower sperm concentration, total number, and forward motility, and with a higher seminal leukocyte concentration compared with patients with CBP alone and MAGI. Sperm normal morphology was similar in the groups of patients. All sperm parameters did not differ significantly in both groups of patients without MAGI. With ultrasound evaluation, a significantly higher frequency of dilatation of Prostatic Venous Plexus was found in patients with CBP plus IBS (75%) compared with patients with CBP alone (10%). Patients with CBP plus IBS had a significantly higher frequency of MAGI compared with patients with CBP alone. This was associated with worse sperm parameters and, hence, poorer reproductive prognosis. We suggest searching for the presence of IBS in patients with prostatitis syndrome, in particular when CBP and/or worse sperm parameters are present. Finally, this is the first observation on ultrasound examination of the anatomical space between the posterior wall of the prostate and the anterior wall of the rectum reported in patients with CBP and IBS. Further studies should clarify the meaning of the ultrasound findings.

Prostatic Venous Plexus ultrasonic guidance for Prostatic inflammation
1991Co-Authors: Chengkeng Chuang, M K LaiAbstract:The Ultrasonic features of the normal prostate, benign Prostatic hyperplasia and Prostatic carcinoma are well known, but ultrasonic diagnosis of prostatitis is still questionable. We studied 190 cases of transrectal sonogram for Prostatic disease; 89 of them had prominent Prostatic Plexus. When compared with clinical and pathological results, Prostatic Venous Plexus should be considered as a normal anatomical features in only 28.5 percent of them with Prostatic inflammation. When Prostatic Venous Plexus is associated with periurethral halo zone and/or Prostatic calculi, the diagnosis of Prostatic inflammation can be made.
