Urodynamic features of pelvic plexus injury

Abstract

Benign and malignant neoplasms arising in and around the pelvic structures may cause urinary obstruction by mechanical compression of the bladder or proximal urethra. These neoplasms less commonly cause neurogenic voiding dysfunction. Herein we describe the urodynamic abnormalities in a young man with massive involvement of the true pelvis with choriocarcinoma. Destruction of the pelvic plexus produced deficits of parasympathetic, sympathetic and somatic innervation of the bladder and urethra. The value of urodynamic evaluation as a neurologic test of thoracolumbar and sacral cord function is demonstrated.
