Can endometriosis cause occasional symptoms of a uti?

Rarely: Dysuria, or burning with urination, is not caused by endometriosis and should be investigated as a uti. However, the abdominal symptoms of uti, including suprapubic discomfort, could sometimes be caused by endometriosis. Typically endometriosis causes abdominopelvic pain that is distinct from uti; until a certain alternate diagnosis is made, UTI symptoms should be worked up as uti.

Yes: Endometriosis is frequently associated with interstitial cystitis. This is where you feel like you have a UTI but there are no bacteria. In many patients the endo causes so many impulses along the pelvic nerves that the signals start going backwards and cause neurogenic inflammation that triggers the bladder pain and sensitivity. All causes of pelvic pain need to be identified for adequate relief.
