Assessment of voiding dysfunction in men with acute epididymitis.

Fifteen men with a recent attack of acute epididymitis were examined urodynamically and endoscopically after the symptoms had resolved. Thirteen of the 15 patients had abnormal voiding. Two patients had stricture formation in the posterior urethra, one had benign prostatic hyperplasia, one had bladder neck sclerosis, and 4 had detrusor-external sphincter dyssynergia. Three patients including the one with prostatic enlargement presented abdominal straining exceeding 50 cm H2O during micturition. The cause of an obstructive voiding pattern could not be established in 3 patients. The results support the theory of urethrovasal reflux due to a high hydrostatic pressure at the collicular level as a pathophysiological factor in acute epididymitis.
