Lower UTI etiology
|
colonization of bladder epithelium by uropathogens (mostly E. coli 85%; S.saphrophyticus 10-15%)
|
|
lower UTI risks
|
"female>males, spermicide, sex, previous UTI, first degree female with UTI hx,
in elderly: decreased estrogen, decreased bladder tone, impaired bladder emptying, incontinence, catheters, neurogenic bladder" |
|
Lower UTI symptoms
|
"dysuria, internal burning, hematuria, nocturia, urgency, frequency, stress/urge incontinence, malodorous cloudy urine, poor sensation of emptying
in elderly: FTT, agitation, altered mental status, incontinence" |
|
Lower UTI signs
|
"urine microscopy: >3-5 WBC, +/- RBCs, + bact
urine dipstick: +/- RBCs, + nitrites (gram - present), + leukocyte esterase" |
|
Lower UTI diagnostics
|
C/S gold standard: If recurrent UTI without culture in last year
Symptoms persist or recur within three months following prior antimicrobial therapy Diabetes Resistant pattern on previous sensitivities Suspect pyelonephritis Equivocal data Pregnancy Confused, agitated older adults with no identified source of behavior change Urine microscopy: spun clean catch urine sediment, >5 WBC/ HPF, maybe RBC, bacteria Dipstick not sensitive in small colony, looking for maybe RBC, nitrites, leukocyte esterase/ WBC Consider pelvic exam, foreign body, STI, discharge, mass, lesions |
|
Lower UTI Tx
|
TMP/SMX-1ds tablet po BID x 3 days OR nitrofurantoin (macrobid) 100mg BID x 5 days OR fosfomycin (monurol) 3 gm powder x 1 dose
If resistance or allergy: Ciprofloxacin (Cipro®) 250 po BID for 3 days Levofloxacin (Levaquin®) 250 or 500 mg po BID for 3 days sx relief: phenazopydridine (pyridium) 200 mg TID prn If relapse (within 1-2 weeks): Cipro and culture |
|
Lower UTI Tx in resistant or allergy to first line treatment
|
in resistant or allergy to 1st line: cipro 250mg BID x 3 days OR levofloxacin 250 or 500mg BID x 3 days
|
|
Lower uti Tx in elderly
|
in elderly: if crcl <30 decrease fluoroquinolone dose by half; no macrobid if crcl<40;
|
|
Lower UTI tx pregnancy
|
in preg: amox, nitrofurantoin, cephalosporin
need 10-14 day course in males, DM, structural abnormality, obstruction, stones, immunosupp, preg, indwelling caths in relapse: if sx return in 1-2 weeks treat wih fluoroquinolone (get culture) |
|
Recurrent lower UTI tx
|
Two or more UTIs in 6 months (> 3 in a year)
use prophy (half dose, q HS x 3-6mo), post-coital (take 30 min before or after), |
|
Lower UTI Edu
|
"impt to complete trmt, avoid spermicide, prevent constipation/diarrhea, hypoestrogen
no evidence to support increased fluid, improved perineal hygiene, regular toileting, no bubble baths, urinate after sex, cranberry juice" |
|
Upper UTI risk
|
"- Pregnancy
- Bacterial capacity for ascent, compromise in host defenses, ability of bacteria to migrate ureter without washout - Inflammatory changes in the bladder may induce alteration in competence of ureterovesical junction - Elderly have increased incidence of upper, assess renal fx" |
|
Upper UTI symptoms
|
"- CVA tenderness
- Fever - Malaise - Abdominal pain - N/V - Chills" |
|
Upper UTI signs
|
"- Temp >38.3
- +/- septic shock - + casts" high blood pressure and pulse |
|
Upper UTI Dx
|
Urine microscopy: spun clean catch urine sediment, >5 WBC/ HPF, maybe RBC, bacteria, white casts
CBC, assess renal fx |
|
Upper UTI Tx
|
"- Fluoroquinolones (only medication recommended for outpatient)
-Cipro 500 mg po BID x 7 days Ciprofloxacin good choice for uncomplicated upper tract if resistance pattern less than 10% - Levofloxacin, 750 mg qd x 5 days OR - TMP- SMX 1 DS tab BID, 14 day course if culture sensitive - Nitrofurantoin and Fosfomycin NOT useful for upper AND Ceftriaxone 1g IV x 1" |
|
Intercystitis and bladder pain syndrome symptoms
|
Urinary frequency, urgency, dysuria, small voids, suprapubic pain/pressure relieved by voiding, pelvic/perineal/anterior vaginal wall pain, lower abd or back pain. Periods of exacerbation/remission
|
|
IC/BPS risks
|
Median age at Dx: 42-46; FEMALE; Concomittent pain syndromes, depression, emotional/physical abuse
|
|
IC/BPS etiology
|
?Inflammatory, allergic, neurogenic, epithelial dysfunction. Injury/dysfuntion of cytoprotective GAG layer of bladder
|
|
IC/BPS Signs
|
Suprapubic tenderness, anterior vaginal/perineal discomfort
|
|
IC/BPS DX
|
Urinalysis, STI screen, cytoscopy, post void residual
R/o UTI's, pelvic/bladder CA, cystitis, renal calculi, overactive bladder, endometriosis, STI, vaginitis; REFER |
|
IC/BPS Tx
|
1) local heat or cold, avoid activities and food associated, voiding diary, bladder training 2) pelvic PT,
Systemic pharma: Hydroxyzine, Amitriptyline, anticholinergics, antispasmodics 3) cytoscopy or hydrodistension Tx 4) sacral neuromodulation 5) cyclosporine or botulinum toxin 6. urinary divrsion |
|
IC/BPS edu
|
Dietary modifications: low acid, low arylalkylamines, increase fluids; bladder retraining, exercise, psycho/social support, stress reduction
