E. Coli
others can be: Enterobacteriaceae Klebsiella Proteus Staph saprophyt
Fix
Urinalysis (either by microscopy or by dipstick) for evaluation of pyuria is a valuable laboratory diagnostic test for UTI. It is not indicated in women with typical symptoms of acute simple cystitis (in whom the diagnosis can reliably be made on symptoms alone), but it can be helpful in cases in which the clinical presentation is not typical.
Pyuria is present in almost all women with acute cystitis; its absence strongly suggests an alternative diagnosis.
Dipsticks are commercially available strips that detect the presence of leukocyte esterase (an enzyme released by leukocytes, reflecting pyuria) and nitrite (reflecting the presence of Enterobacteriaceae, which convert urinary nitrate to nitrite). The dipstick test is most accurate for predicting UTI when positive for either leukocyte esterase or nitrite, with a sensitivity of 75 percent and a specificity of 82 percent.
However, results of the dipstick test provide little useful information when the clinical history is strongly suggestive of UTI, since even negative results for both tests do not reliably rule out infection in such cases.
UTI Treatment
simple uncomplicated with no MDR risk factors
start nitrofurantoin, TMP-SMX, or fosfomycin.
After this, Augmentin, or some cephalosporins such as Keflex
After this fluoroquinolones, then Cipro or Levaquin
Acute complicated UTI =
Pyelonephritis
Cystitis S/S
dysuria, urinary frequency and urgency, suprapubic pain, and hematuria
may also have fever chill rigors fatigue malaise
Pyelonephritis s/s
fever, chills, flank pain, costovertebral angle tenderness, and nausea/vomiting
Acute complicated UTI can also present with
bacteremia, sepsis, multiple organ system dysfunction, shock, and/or acute renal failure
More likely with UT obstruction, physical abnormality
Pyelonephritis DX
Leukocyte left shift (CBC)
UA shows pyuria, bacteriuria, and possible hematuria
Urine Culture
If very complicated pyelonephritis, then renal U/S may show hydronephrosis secondary to obstruction
If suspect pyelonephritis on inpatient
Treat with ESBL and MRSA coverage-Imipenem or meropenem or doripenem plus vancomycin
If no risk factors for MDR gram- infection then either: ceftriaxone, piperacillin-tazobactam, ciprofloxacin, or levofloxacin with possible vancomycin
Pyelonephritis outpatient
mild to moderate and out patient
they get cipro or levoquine
Urethritis
Urethritis, or inflammation of the urethra, is a common manifestation of sexually transmitted infections among men
Gonoccocal Urethritis
bug
Neisseria gonorrhea
nonGonoccocal Urethritis
bugs
Chylamydia trachomatis m genitalium U urealyticum T vaginalis others
Urethritis risk factors
Family (genetic)
multiple sex partners
anal / risky types of sex
damaged condoms
Infectious urethritis is typically caused by
sexually transmitted pathogen;
thus, most cases are seen in young, sexually active men
2 common bugs for Infectious urethritis
Neisseria gonorrhoeaeandChlamydia trachomatisare common
also Mycoplasma genitalium
Urethritis presentation
Dysuria = chief complaint in men
others: pruritus, burning, and discharge at the urethral meatus.
can have watery or purulent or mucoid discharge
Urethritis can be diagnosed in with one of the following
Mucopurulent or purulent discharge on examination
≥2 white blood cells (WBC) on gram stain
Positive leukocyte esterase (“dipstick”) or the presence of ≥10 WBCs
If none of these findings are present, a presumptive or suspected diagnosis of urethritis can be made in sexually active men with suggestive symptoms.
Urethritis Tx gonococcal
IM 500mg Cef
if Chlamydia is suspected = also give doxy 100 BiD x 7d
Urethritis Tx nongonococcal
when gonococcal is not found, treat for suspected chylamydia
Azithromycin
Urethritis Prevention
refrain from sex x 7 days
follow treatment
testing at 3 months to rule out reinfection (chlamydia/gonorrhea)
Acute Epididymitis
Acute epididymitis is most commonly infectious in etiology but can also be from noninfectious causes such as trauma and autoimmune diseases
N. gonorrhoeaeandC. trachomatismost common in under 35
E.coli in older men
Intracellular enterococci
Gonorrhea
Epididymitis risk factors
sex with multpile partners not using condoms uncircumsized recent surgery structural problems catheter use.
Epididymitis & orchitis
Inflammatory conditions are more common in epididymis than in testes
But syphillis will begin in the testes
Most common cause of scrotal pain in adults in the outpatient setting
Acute epididymitis
epididymitis presentation
Testicular pain with tenderness and swelling on palpation of the affected epididymis, which is located posteriorly on the testis.
Prehn sign
Relief of scrotal pain after elevation
not a reliable way to distinguish between epididymitis and torsion
epididymitis dx
Dx is made presumptively based on history and physical examination after ruling out other causes requiring urgent surgical intervention
A urinalysis, urine culture, and a urine nucleic acid amplification test (NAAT) forN. gonorrhoeaeandC. trachomatisshould be performed
Id of pathogen on urine or swab testing supports the presumptive diagnosis.
Most common organisms responsible for acute epididymitis in men under the age of 35
N. gonorrhoeaeandC. trachomatis
Most common organisms responsible for acute epididymitis in older men
Escherichia coli, other coliforms, andPseudomonasspecies are more frequent in older men, often in association with obstructive uropathy from benign prostatic hyperplasia
epididymitis Tx general
Management of acute epididymitis varies according to its severity.
Most cases can be treated on an outpatient basis with oral antibiotics, nonsteroidal antiinflammatory drugs (NSAIDs), local application of ice, and scrotal elevation.
Acutely ill patients may warrant hospitalization for parenteral antibiotics and intravenous hydration.
