Just some of the facts with regard to UTI's:
1. Cranberry juice (not the high sugar containing cocktail) does not treat a UTI. There has been many published studies showing the efficacy of cranberry juice at preventing UTI's, not through the change in acidity but by altering the bacteria's ability to adhere to the transitional epithelium of the urinary tract.
2. Try to avoid the use of OTC medications such as AZO, Uristat...unless you are seeking temporary relief until you can get into your physician's office. These medication are simply bladder analgesics and antispasmodics and do nothing to treat the underlying infection. Most women with a history of UTI's are aware of the need to see their physician for antibiotic management and use the OTC meds as a temporary measure until they can start treatment. Many of the younger girls, especially 1st time UTI's tend to delay treatment because they alter their symptoms and often arrive with a more serious kidney infection (pyelonephritis). The OTC medications also alter the the standard urinalysis and require microscopic observation and culture to confirm the diagnosis.
3. Low back pain does not mean your kidney is involved! Your kidneys actually reside high up on the back and the low back pain you are typically experiencing is the radiation pattern to the low back from bladder irritation.
If you have back pain (aka CVA tenderness) in conjunction with fever, nausea, UTI symptoms and either a positive U/A or C/s the diagnosis of pyelonephritis has been established and the proper treatment can be initiated.
4. Treatment of acute uncomplicated UTI's (cystitis) requires antibiotics and the duration of treatment is determined by what other underlying problems you have such as diabetes, whether you are pregnant, your age...
If you have no significant risk factors or chronic diseases that place you at increased risk of more significant problems such as sepsis, pyelonephritis, renal failure...a 3 day course of antibiotics are indicated and have been found to be just as effective as a 7 day course. The typical antibiotics we prescribe are Macrobid/Macrodantin (nitrofurantoin), Bactrim/Septra (trimethoprim sulfamethoxazole), Cipro (ciprofloxacin), and Levaquin (levofloxacin). There are others but these tend to be the most common. I personally treat my uncomplicated UTI's for 5 days. If you have risk factors or significant history of other medical problems that place you at risk for the development of more serious complications the duration of treatment is extended to 7-10 days.
The treatment of pyelonephritis usually involves either inpatient treatment for IV antibiotics or outpatient treatment if the facility is equipped to administer IV medications. The treatment usually involves either IV Rocephin (ceftriaxone) or Levaquin (levofloxacin) until your white counts begin to fall on your CBC (blood work) and until you are afebrile for at least 24 hours. After that time you are converted to the oral (PO) form of the antibiotics for an additional 7-10 days. Given the discomfort and nausea associated with pyelonephritis, your doctor will also usually prescribe a pain medication and antiemetic to prevent nausea/vomiting.
The antispasmodics/bladder analgesics most commonly used are Pyridium, Levsin (hyocyamine), Prosed DS, Urised, Methylene blue.. but many of these can and do turn your urine blue, orange....depending on which medication is used.
Most of the typical bacteria that cause UTI's originate from the GI tract with the most common being E. Coli and Enterococcus. Others include Proteus, Staphylococcus, Klebsiella, Pseudomonas.
Risk factors for UTI's are numerous. In younger children it can be due to poor hygiene, vesicoureteral reflux, infrequent voiding, diarrhea, urethral irritation from bubble baths...or an anatomical abnormality with regard to the ureter or kidney. In sexually reproductive age women, sexual intercourse tends to top the list. Postmenopausal women tend to have hormonal changes that predispose them to UTI's. Other causes can include but are not limited to previous pelvic surgeries such as a hysterectomy/bladder sling/...that can possibly alter the normal orientation of the anatomy which can lead to UTI's. Recent hospitalization, instrumentation, or catheter placement. Immunosuppression from diabetes, HIV, medications...can predispose you to UTI's. Kidney stones (especially struvite), polycystic kidneys, sickle cell disease, pregnancy, fistulas (connections between organs that should not be there such as between the colon and bladder. This can occur through instrumentation from other surgeries or from medical conditions such as crohns/UC), and even other diseases that are occuring simultaneously such as a yeast infection or bacterial vaginosis that irritate and inflame the urethra and set you up for a UTI. Needless to say there are many causes and treatments available but if you suspect that you have a UTI please go see your doctor and don't self treat.
If you have a negative urinalysis in the office most doctors will still treat with antibiotics because it is possible to have a UTI with a negative in office urine. If the cultures consistently come back negative and you are experiencing urinary tract symptoms we start looking for other potential causes that can mimick the symptoms of a UTI such as a bacterial vaginosis, an STD such as gonorrhea/chlamydia, medications, yeast infection, or interstitial cystitis. These obviously require other diagnostic tests such as cultures, KOH and wet prep, cystoscopy, ultrasound.....
Another interesting tidbit of information: anything that is inflamed and touching the bladder can cause blood in the urine and urinary tract symptoms such as a ovarian cyst, appendix, diverticulitis, PID...so don't delay in seeking medical treatment. Especially if other symptoms are present (fever, abdominal pain, vaginal discharge, dyspareunia...) in addition to the urinary symptoms (dysuria, urgency, frequency...).
5. If you are a female that consistently gets UTI's following intercourse and you have tried all the recommendations to prevent this (bathing after intercourse, voiding your bladder after intercourse..), it is reasonable to take a single dose of the antibiotic after a sexual encounter. This is taking into account that you are in a stable monogomous relationship where there is no risk of contracting an STD and you have culture proven UTI's.
Sorry for the run on sentences and the basic nature of the response but it is easy to get lost in the medical terminology and get nothing out of the information being presented.
