23
Q
Fix
A
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.
24
Q
UTI Treatment
simple uncomplicated with no MDR risk factors
A
start nitrofurantoin, TMP-SMX, or fosfomycin.
After this, Augmentin, or some cephalosporins such as Keflex
After this fluoroquinolones, then Cipro or Levaquin
25
Acute complicated UTI =
Pyelonephritis
26

dysuria, urinary frequency and urgency, suprapubic pain, and hematuria
may also have fever chill rigors fatigue malaise
27

fever, chills, flank pain, costovertebral angle tenderness, and nausea/vomiting
28
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
29
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
30
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
31

36
Infectious urethritis is typically caused by
sexually transmitted pathogen;
thus, most cases are seen in young, sexually active men
37
2 common bugs for Infectious urethritis
Neisseria gonorrhoeae and Chlamydia trachomatis are common
also Mycoplasma genitalium
38
Urethritis presentation
Dysuria = chief complaint in men
others: pruritus, burning, and discharge at the urethral meatus.
can have watery or purulent or mucoid discharge
39
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.
40
Urethritis Tx gonococcal
IM 500mg Cef
| if Chlamydia is suspected = also give doxy 100 BiD x 7d
41
Urethritis Tx nongonococcal

42
Urethritis Prevention
refrain from sex x 7 days
follow treatment
testing at 3 months to rule out reinfection (chlamydia/gonorrhea)
43
Acute Epididymitis

44
Intracellular enterococci
Gonorrhea
45

Testicular pain with tenderness and swelling on palpation of the affected epididymis, which is located posteriorly on the testis.
49
Prehn sign
Relief of scrotal pain after elevation
| not a reliable way to distinguish between epididymitis and torsion
50
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) for N. gonorrhoeae and C. trachomatis should be performed
Id of pathogen on urine or swab testing supports the presumptive diagnosis.
51
Most common organisms responsible for acute epididymitis in men under the age of 35
N. gonorrhoeae and C. trachomatis
52
Most common organisms responsible for acute epididymitis in older men
Escherichia coli, other coliforms, and Pseudomonas species are more frequent in older men, often in association with obstructive uropathy from benign prostatic hyperplasia
53
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.
54
epididymitis Tx
under 35 at risk std = coverage for Gonorrhea/chlamydia
500 IM Cef plus Doxy 100mg Bid x 10 days
Patients 35 years of age or older
low sexual risk
levofloxacin 500 mg orally once daily for 10 days
insertive anal intercourse
Cef 500 mg IM, plus a fluoroquinolone (levofloxacin 500 mg orally once daily for 10 days).
55
acute epididymitis should improve when?
within 48 to 72 hours after starting appropriate antibiotic therapy
If not better, other causes of scrotal pain should be considered. Scrotal ultrasound and referral to a urologist for consultation are advised.
56
Orchitis causes
Inflammation / infection of the testicles
Swelling, pain, tenderness, erythema, shininess
Viral: mumps, coxsackie, echovirus, parvovirus
Bacterial : brucellosis
57
Orchitis Presentation
Unilateral testicular swelling and tenderness occur.
| Fever and tachycardia are common
58
Orchitis DX
U/A reveals pyuria and bacteriuria with infection.
Positive urine cultures.
U/S is useful if possible abscess or tumor is suspected and to rule testicular torsion
59
Orchitis Tx
If mumps is the cause,
symptomatic relief with ice and analgesics,
If bacteria is the cause,
see epididymitis. Evaluate any scrotal masses.
60

2: Chronic Bacterial Prostatitis
3: Chronic prostatitis, chronic pelvic pain syndrome
4: Asymptomatic inflammatory prostatitis
61
Prostatitis Risk Factors

Altered prostate secretory functions
(low zinc, decreased prostate antibacterial factor)
Manipulation of prostate
(catheters, instruments, prostatectomy)
63
Prostatitis bugs

Of Enterobacteriaceae, Escherichia coli is the most typical, followed by Proteus.
E.coli 58-88%, Proteus 3-6%, Pseudo 3-7%
Other entero 3-11%
The pathogens associated with acute prostatitis reflect the spectrum of organisms causing cystitis, urethritis, and deeper genital tract infections (such as epididymitis).
64

65
main function of the urinary system
eliminate the waste products of metabolism from the body by forming and excreting urine
