Bladder exstrophy‐epispadias complex: Prostatic evaluation by transrectal ultrasonography

Seven patients with bladder‐exstrophy‐epispadias complex underwent high resolution prostatic ultrasonography in order to establish the presence and appearance of their prostate gland and seminal vesicles. Six patients had been born with classic bladder exstrophy, and one patient with complete epispadias. The size of the prostate gland was in the normal range in three patients. Three patients had small glands, and in one patient no prostatic tissue could be identified. Two patients showed an unusual position or echoappearance of their glands. The seminal vesicles in five patients were relatively large, contained multiple cystic spaces, and/or extended posteriorly and inferiorly to the prostate gland proper. Our study demonstrates that the prostate gland and seminal vesicles are present in patients with bladder exstrophy. The unusual appearance, position, and size in most patients, however, suggests faulty embryologic development or changes secondary to surgery reflecting the complex nature of the condition. Likewise, the enlarged seminal vesicles may indicate impaired drainage of these structures secondary to the initial bladder closure or subsequent bladder neck reconstruction.
