Genitourinary Conditions Flashcards
What are the two types of hematuria?
Gross hematuria - visible to the naked eye.
Microscopic hematuria - detectable by examination of sediment, microscopy or urinalysis.
Define the sources and percentages of patients with microscopic hematuria.
Upper urinary tract source - 10%
Stone disease - 40%
Medical kidney disease - 20%
Renal cell carcinoma - 10%
Urothelial cell carcinoma of the ureter or renal pelvis - 5%
Microscopic hematuria in males is most commonly due to what condition?
Benign prostatic hyperplasia.
This type of gross hematuria is defined as the presence of blood at the beginning of the urinary stream that clears during the stream.
Initial hematuria, implies anterior (penile) urethral source.
This type of gross hematuria is defined as the presence of blood at the end of the urinary stream.
Terminal hematuria, implies bladder neck or prostatic urethral source.
This type of gross hematuria is defined as the presence of blood throughout the urinary stream.
Total hematuria, implies bladder or upper tract source.
What does hematuria associated with renal colic imply?
Ureteral stone.
In the absence of other symptoms, gross hematuria can be indicative of what?
A tumor.
Proteinuria and casts in a urinalysis suggest what origin?
Renal.
What type of diagnostic imaging is indicated for patients with gross hematuria or those over 35 years old with asymptomatic hematuria?
Cystoscopy.
Evaluates for:
-Bladder or urethral neoplasm

-Radiation or chemical cystitis
What type of bacteria is responsible for the majority of UTIs (cystitis)?
Coliform bacteria, E. coli being the most common. Ascending infection from the urethra is the most common route.
Uncomplicated cystitis in men is rare - what does it imply?
Pathologic process such as infected stones, prostatitis, or chronic urinary retention. Requires further evaluation.
Signs and symptoms of cystitis.
Irritative voiding symptoms:
-Frequency

Usually afebrile
Treatment of cystitis in women.
Antibiotics:
Ciprofloxacin
-250mg q12h PO for 3 days

When are women considered candidates for prophylactic treatment of cystitis? What are the 3 most commonly used oral prophylactic agents?
Women who have more than 3 episodes of cystitis per year.
Trimeothoprim-sulfamethoxazole (Bactrim)
Nitrofurantoin (Macrobid)
Cephalexin
Single dosing at bedtime or prior to intercourse is the recommended schedule for all 3.
What is the first line treatment of pyelonephritis?
Ciprofloxacin
-750mg q12h PO 7-14 days
This is an infectious inflammatory disease involving the kidney parenchyma and renal pelvis.
Pyelonephritis
Gram-negative bacteria are the most common causative agents; gram-positive are less commonly seen.
Pyelonephritis infections usually ascend from the lower urinary tract, with the exception of what agent?
S. aureus infections which spread by a hematogenous route.
Signs and symptoms of pyelonephritis.
Fever
Flank pain
Irritative voiding symptoms
Shaking chills
Associated nausea and vomiting
Diarrhea
Tachycardia

Leukocytosis and a left shift.
What is a major complication of pyelonephritis?
Sepsis and shock.
Acute prostatitis is usually caused by what strains of bacteria?
Gram-negative E. coli and Pseudomonas.
What are the signs and symptoms of prostatitis?
Warm and exquisitely tender prostate - hallmark symptom.
Perineal, sacral or suprapubic pain.
Irritative voiding symptoms.
Obstructive symptoms which can lead to urinary retention.
Outpatient treatment of acute prostatitis.
Antibiotics:
Ciprofloxacin, Levofloxacin or Bactrim
Analgesics/pain:
Acetaminophen or NSAIDs
Stool softeners
For a patient with acute prostatitis treated with IV antibiotics, how long are oral antibiotics prescribed to finish the full antibiotic treatment?
4-6 weeks.
For a patient with acute prostatitis who develops urinary retention, what type of treatment is required?
Percutaneous suprapubic tube
*Urethral catheterization is contraindicated.
A patient presents with irritative voiding symptoms, low back and perineal pain, and suprapubic discomfort.
He has a history of UTIs. His physical exam is unremarkable. What is his diagnosis?
Chronic bacterial prostatitis.
A patient’s prostate with chronic bacterial prostatitis may present in what way?
Normal, boggy or indurate.
What is the treatment of chronic bacterial prostatitis?
Bactrim
-Associated with the best cure rates.
Or: Cipro, Levofloxacin.
NSAIDs and sits baths for symptoms.
What are the two forms of infectious epididymitis?
Sexually transmitted
-Typically men under 40
-Associated with urethritis
-Result from Chlamydia or Gonorrhea
Non-sexually transmitted
-Typically older men
-Associated with UTIs and prostatitis
-Caused by gram-negative rods
A patient presents with unilateral testicular swelling that is tender and painful to palpation. He has a fever and associated symptoms of urethritis and cystitis. What is his diagnosis, and what are three common causes of this condition?
Epididymitis
Acute physical strain, trauma, sexual activity.
The special test of elevating the scrotum above the pubic symphysis to test for epididymitis is known by what name? What is a positive finding?
Prehn sign.
Positive finding is if it relieves pain.
How do you treat sexually and non-sexually transmitted epididymitis?
Sexually:
Ceftriaxone AND Doxycycline.
Non-sexually:
Bactrim, Cipro or Levofloxacin

Bed rest
Scrotal support
Ice packs
NSAIDs
Which sex is more commonly affected by urolithiasis, and what is the ratio?
Men are more commonly affected - 2.5:1
*Initial presentation occurs between the 3rd and 5th decade of life.
How many types of urinary stones are there, and what is the major type?
5 major types.
Calcium accounts for 85% of them.

High humidity and heat.

Pain occurs suddenly, localized to a flank.
Nausea and vomiting are common.

Patients increasing fluid intake to avoid urinary stones should drink water at what intervals?
During meals, 2 hours after each meal, prior going to sleep and enough to wake the patient to void, and additionally during the night
