Question: what causes chronic urinary retention?
Answer: Pathophysiology. The most common cause in men is Benign Prostate Hyperplasia (BPH). Other common obstructive causes include urethral strictures or prostate cancer. In women, pelvic prolapse (such as cystocele, rectocele, or uterine prolapse) or pelvic masses (such as large fibroids) can also cause chronic retention.
