Can bladder endometriosis cause urinary retention?

Yes—bladder endometriosis can contribute to urinary retention in some patients, especially when endometriosis involves the bladder wall muscle (deep bladder endometriosis) or when nearby deep disease and pelvic floor guarding disrupt normal bladder emptying. It’s not the most common urinary symptom pattern, but it can happen alongside more typical complaints like bladder pressure, pain with urination, urgency, and frequency.

Retention can be intermittent (for example, flaring around your cycle) or feel like incomplete emptying, hesitancy, or needing to strain to urinate. Because urinary symptoms overlap with conditions like bladder pain syndrome/interstitial cystitis, pelvic floor dysfunction, and ureter-related problems, a normal urine culture doesn’t rule out a structural or endometriosis-related cause.

In our evaluation, we look at the full symptom pattern and flare timing, and we use targeted imaging such as expertly interpreted pelvic ultrasound and/or MRI to assess the bladder and surrounding structures. If your symptoms include retention or significant voiding difficulty, it’s also important to assess the ureters and kidneys, since urinary-tract involvement can coexist with deep endometriosis. If you’d like, you can reach out to schedule a consultation so our team can help clarify what’s driving your symptoms and what treatment options make the most sense for your goals.
