Q

Complications of pyelonephritis?

Study These Flashcards
A
  • Sepsis and shock
  • Abscess formation from inadequate therapy
  • Catheter drainage might be necessary
25
MEDEVAC to Urology or infectious disease for pyelonephritis when?
- Evidence of complicating factors - Severe infections - Evidence of sepsis - Need for parental antibiotics - Absence of clinical improvement in 48 with oral antibiotics
26
What is acute prostatitis?
Inflammation and infection of prostate gland usually caused by gram-negative rods (E. coli and Pseudomonas)
27
Most likely routes of infection for prostatitis?
- Ascent up the urethra | - Reflux of infected urine
28
S/s of prostatitis?
- Perineal, suprapubic, or sacral pain - Fever, high - Irritative voiding symptoms - Obstructive symptoms that may lead to urinary retention - Warm and tender prostate
29
Lab findings prostatitis?
- Leukocytosis and a left shift on UA - Pyuria, Bacteriuria, and hematuria on UA - Urine cultures demonstrate offending pathogen
30
Rad for prostatitis?
No
31
Inpatient treatment of prostatitis?
Ampicillin and gentamicin until 24-48 hours resolution of fever - oral antibiotics for 4-6 weeks
32
Outpatient treatment of prostatitis?
- Cipro - Levofloxacin - Bactrim - Acetaminophen/NSAIDS - Stool softeners
33
What to do if urinary retention develops with prostatitis?
- Percutaneous Suprapubic tube is required | - Urethral catheterization is CONTRAINDICATED
34
MEDEVAC for prostatitis?
- Evidence of urinary retention - Signs of sepsis - Surgical drainage of bladder prostatic abscess - Evidence of chronic prostatitis - Absence of clinical improvement in 48 with oral antibiotics
35
Chronic bacterial prostatitis?
- May evolve from acute prostatitis - Many men have no Hx of acute infection - Gram negative rods are most common - Enterococcus only gram positive organism - Not to be managed by IDC alone
36
S/Sx's of chronic bacterial prostatitis?
- Irritating voiding symptoms - Low back and perineal pain - Suprapubic discomfort - Hx UTI - PE unremarkable - Prostate may be: * Normal * Boggy * Indurate
37
Tx of chronic bacterial prostatitis?
- Bactrim - Cipro - Levofloxacin * Duration lasts 6-12 weeks - NSAIDS - Sitz baths
38
What is Epididymitis?
- Inflammation and/or infection of epididymitis - Can be divided into two categories: * Sexually transmitted forms * Non-sexually transmitted forms - Route of infection is probably urethra to ejaculatory duct
39
Information on sexually transmitted epididymitis?
- Typically occurs in men under 40 year - Associated with urethritis - Results from chlamydia or gonorrhea
40
Information of non-sexually transmitted epididymitis?
- Typically occur in older men - Associated with UTI and prostatitis - Caused by gram negative rods ( E. Coli, Klebsiella)
41
S/Sx's of epididymitis?
- May follow acute physical strain, trauma, or sexual activity - Associated Sx's of urethritis and cystitis - Pain develops in scrotum and may radiate along spermatic cord or to flank - Fever - Scrotal swelling * * epididymis might be distinguishable from testes early on**
42
Later S/Sx's of epididymitits?
- Epididymis and testes can appear as one mass - Prostate may be tender on rectal exam - Prehn sign
43
What is Prehn sign?
Elevation of scrotum above pubic symphysis may relieve pain from epididymitis
44
Imaging for epididymitis?
Scrotal U/S
45
Tx for sexually transmitted epididymitis?

47
Symptomatic relief for Epididymitis?
- Bed rest - Scrotal support - Ice packs - NSAIDS
48
Complications of epididymitis?
- Delayed or inadequate Tx may result in: * Epididymo-orchitis * Decreased fertility * Abscess formation
49
Follow up for epididymitis?
Refer to Urology if: - Persistent symptoms or infection despite antibiotic therapy - Signs of sepsis or abccess formation
50
General considerations for renal calculi/urolithiasis/kidney stones?
- Men are more frequently affected than woman (2.5:1 ratio) - Initial presentation predominantly between 3rd and 5th decade - There are five types urinary stones (calcium most common)
51
What are some contributing factors to renal calculi/urolithiasis?
- High humidity - Elevated temperatures - Sedentary lifestyle - HTN - Carotid calcification - Cardiovascular disease - High protein and salt diet with inadequate hydration
52
What are some sign/symptoms of renal calculi/urolithiasis?
- Sudden pain (may be episodic) - Pain localized to the flank - Pt constantly moving to find comfort - Pain may radiate anteriorly over abdomen - Stone size does not correlate to severity of symptoms
53
How do obstructing urinary stones present?
Acute, unremitting and severe colic
54
Urinalysis finding for urolithiasis/urinary stones?
- Microscopic or gross hematuria (absence does not exclude) | - Urinary pH is a valuable clue
55
Imaging for renal caculi/urinary stone?
- Plain abdominal radiograph - Renal U/S - Spiral CT with Pt in prone position
56
Tx for urinary stone?
- Forced IV fluids or diuresis in counterproductive - Medical expulsive therapy (Alpha blockers, NSAIDS, corticorsteroids) - Surgical Tx
57
Prevention of renal calculi?
- Dietary modification: * Increased fluid intake * Restrict sodium intake * Spread animal protein throughout day
58
Complications of urolithiasis?
Obstructing stone with an associated infection is a medical emergency ** MEDEVAC **
59
Referral to urology for urolithiasis is warranted when?
- Obstructing stone with associated infection - Stone fails to pass after 4 weeks - Fever - Intolerable pain - Persistent Nausea/vomiting
