What is happening
A urinary tract infection starts when bacteria from the gut colonize the skin and tissue around the urethra and then travel up into the bladder. Everyone is exposed to those bacteria. What changes after menopause is how well the tissue resists them.
Before menopause, estrogen keeps vaginal glycogen high, which feeds lactobacilli, which produce lactic acid, which keeps vaginal pH around 4. That acidic environment suppresses E. coli and the other organisms that cause most UTIs. After menopause, glycogen drops, lactobacilli decline, and pH rises toward 6 or 7. Gut bacteria colonize far more easily. At the same time the urethral and bladder neck tissue thins and loses its blood supply, which weakens a second line of defense.
Add anything that keeps urine sitting in the bladder — prolapse, pelvic floor dysfunction, incomplete emptying — and the cycle sustains itself.
Why this is a urology problem
Many women spend years on a loop: symptoms, urgent care, antibiotic, brief relief, repeat. Each visit treats an episode. Nobody treats the pattern.
Our approach is to treat the episode and then step back and ask why it keeps happening. We confirm infections by culture so we know we are treating something real. We check whether your bladder empties. We look at whether GSM is present, because it usually is and it is fixable. We check for prolapse, stones, and anatomic causes when the history suggests them. Then we build a prevention plan.
What a visit looks like
Bring whatever records you have: dates of infections, culture results, and which antibiotics you have taken. That history shapes the plan more than anything we can measure on the day.
A first visit usually includes a urinalysis and culture, a post-void residual measurement by bladder ultrasound, and a pelvic exam to assess the tissue and check for prolapse. Cystoscopy and imaging are not routine — the guideline reserves them for women with specific findings such as persistent blood in the urine, an unusual organism, stones, or failure to respond.
Most women leave with a prevention plan built around vaginal estrogen, a clear rule for when to test rather than assume, and a plan for what to do if an infection does happen. Antibiotic prophylaxis is used selectively and with an exit strategy, not indefinitely by default.
