Thekey differencebetween UTI and overactive bladder是在膀胱和肾脏被细菌感染时，UTI是一种医疗状况，而过度活跃的膀胱是一种医疗状况，当膀胱肌肉过度收缩时会发生。
What is UTI (尿路感染）?
Urinary tract infection(UTI) is a medical condition that occurs when the bladder and kidneys are infected by bacteria. UTI is an infection in any part of the urinary system, including kidneys, bladders,ureters, and urethra. However, most UTI infections involve the bladder and the urethra. Women are at a greater risk of developing a UTI than men. The infections that are limited to the bladder can be painful and annoying. Serious consequences can occur if the infections spread to the kidneys. The urinary tract infection symptoms may include a strong and persistent urge to urinate, a burning sensation when urinating, passing frequent and small amounts of urine, urine that appears cloudy, urine that appears red, bright pink or cola colored urine, strong smelling urine, and pelvic pain in women.
UTI感染有三种主要类型：肾脏（急性pyelonephritis），膀胱（膀胱炎), and urethra (urethritis). The infections in the bladder (cystitis) are caused byEscherichia coli,which is a bacterium commonly found in the gastrointestinal tract. Sexual intercourse can cause cystitis. But all women are at higher risk of cystitis because of their anatomy (a short distance from the urethra to the anus and the urethral opening to the bladder). Moreover, urethritis can occur when GI bacteria spread from the anus to the urethra. Women have their urethra close to the vagina, and sexually transmitted infections like gonorrhea, chlamydia, and mycoplasma can cause urethritis.
UTI can be diagnosed through urine sample analysis in the laboratory, urine cultures, CT scans, MRIs, and cystoscopy. Furthermore, treatments for UTIs are antibiotics such as trimethoprim/sulfamethoxazole, fosfomycin, nitrofurantoin, cephalexin, ceftriaxone, and vaginal estrogen therapy.
What is Overactive Bladder?
Diagnosis of overactive bladder can be performed through medical history, physical examination (which includes rectal exam and pelvic exam in women), urine sample to test infection, traces of blood or other abnormalities, and neurological exams. Furthermore, treatments for overactive bladder include behavioral therapies, medications to relax the bladder (tolterodine, oxybutynin, solifenacin, fesoterodine, and mirabegron), bladder injections (onabotulinumtoxinA), nerve stimulation, percutaneous tibial nerve stimulation (PTNS), and surgery to increase bladder capacity, and bladder removal.
What are the Similarities Between UTI and Overactive Bladder?
- Both UTI and overactive bladder are characterized by a strong, frequent urge to urinate.
- Both UTI and overactive bladder can be diagnosed through urine sample analysis in the laboratory.
- They can be treated through specific medications.

Summary – UTI vs Overactive Bladder
UTI和过度活跃的膀胱是两种导致尿路不适的医疗疾病。UTI is a medical condition that occurs when the bladder and kidneys are infected by bacteria, while overactive bladder is a medical condition that occurs when bladder muscles contract excessively. So, this is the key difference between UTI and overactive bladder.
