UTI/Pyelonephritis

Urethritis
·       STD
·       Discharge
·       Dx: NAAT
·       Tx: Azithromycin + Ceftriaxone
·       F/U: HIV
Asx Bacteuria
·       E.coli / GBS
·       If preg + Asx bactiuria –> Amoxicillin –(allergic?)–> Nitrof
Cystitis
·       E.coli
·       choose either: TMP-SMX / Nitrof / Fibronycin
Pyelonephritis
·       IP (really sick): IV ceftriaxone
·       OP (young and okay): ORAL FQ Ciprofloxacin (10 ds)
·       Change to oral w/ improvement of sx in 48 h
Perinephric Abscess
·       Dx CT / US
·       drainage + pyelo Abx (14 ds)

Urinary tract infection
👾
E coli most common cause
Clx
Cystitis
Dysuria, frequency, urgency, hematuria, suprapubic pain.
Pyelonephritis
Fever >38c, chills, flank pain, costovertebral angle, tenderness & nausea/vomiting,
+/- cystitis symptoms
Dx
Urinalysis & urine culture
Tx
Antibiotics
 Acute pyelonephritis
Uncomplicated
Otherwise healthy, nonpregnant
• Primarily Escherichia coli
oral Fq, TMP-SMX
• IV antibiotics if vomiting, elderly, septic
Complicated
Diabetes,
• urinary obstruction/instrumentation,
• renal failure,
• immunosuppression, hospital-acquired
• ↑ Risk of antibiotic resistance/treatment failure
IV fluoroquinolone. aminoglycoside. extended spectrum beta-
lactam/cephalosporin
 Acute bacterial prostatitis
Path
·       Intraprostatic reflux of pathogens in urine
·       Gram-negative bacilli (Escherichia coli —75%)
Sx
·       Flu-like illness (eg, fever, chills, malaise, myalgia)
·       Lower urinary symptoms (eg, dysuria, urine retention, pelvic pain)
Dx
·       Digital rectal exam — tender, swollen prostate
·       Urine cx
Tx
·       6 weeks of TMP-SMX or FQ
Comp
·       Sepsis: Bacteremia/systemic spread
·       Abscess: Prostatic abscess
·       Chronic prostatitis
 Chronic Bacterial Prostatitis
#
Young & middle-aged men
⤴️ Risk with diabetes, smoking, urinary tract procedure
Path
Coliforms enter from urethra via intraprostatic reflux Escherichia coli causes >75% of cases
Sx
Recurrent UTIs (with the same organism)
Prostatic tenderness and swelling
Pain with ejaculation
History of Abx Tx → Transient improvement
Dx
Pyuria and bacteriuria on UA
Bacteria in prostatic fluid > bacteria in urine
Tx
CIPROFLOXACIN for 4-6 weeks
 Chronic prostatitis / Chronic pelvic pain syndrome
 Sx
·       Pain in pelvis, perineum, genitalia
·       Irritative voiding sx (eg, urgency, hesitancy)
·       Hematospermia, pain w/ ejaculation
Dx
·       Mild prostate tenderness
·       Sterile urine Cx
Tx 
·       Alpha blockers (eg, tamsulosin)
·       Abx (eg, ciprofloxacin), especially if hx of UTI
·       5a-reductase inhibitors (eg, finasteride)
