Urodynamic features of pelvic plexus injury

Area of Science:

• Urology
• Neurology
• Oncology

Background:

• Pelvic neoplasms can cause urinary obstruction via mechanical compression.
• Neurogenic voiding dysfunction is a less common complication of pelvic tumors.
• Choriocarcinoma is a rare but aggressive malignancy.

Observation:

• A young man presented with massive pelvic choriocarcinoma.
• The tumor extensively involved the pelvic plexus.
• This involvement led to widespread denervation of the bladder and urethra.

Findings:

• Urodynamic testing revealed significant abnormalities in bladder and urethral function.
• Parasympathetic, sympathetic, and somatic nerve deficits were identified.
• These deficits correlated with the tumor's destructive impact on the pelvic neural structures.

Implications:

• Urodynamic evaluation can detect neurogenic voiding dysfunction caused by pelvic neoplasms.
• This method serves as a valuable neurologic test for thoracolumbar and sacral cord function.
• Understanding these urodynamic changes is crucial for managing patients with advanced pelvic malignancies.
