Study Notes
General Objectives
- Explore the link between genitourinary anomalies and aviation safety.
- Identify essential examinations for aeromedical evaluations.
- Define appropriate actions for pathological findings.
- Review major conditions affecting the genitourinary system.
Relation to Aviation
- Urological emergencies account for 1% of total in-flight medical emergencies (1368 out of 138,612).
- Incidence rate of urological emergencies: 0.5 per million passengers.
- Temporary incapacity and medical license loss in pilots is noted at 72%.
Aeromedical Examination
- Urinalysis is mandatory for every aeromedical evaluation.
- The selection of dipstick tests is crucial to determine urine components.
Dipstick Urinalysis
-
Specific Gravity: Indicates urine concentration ability, should be > 1022 after 12 hours without food or water.
- Decreased levels (≤1035) suggest dehydration, adrenal insufficiency, liver failure, etc.
-
pH: Important for managing various diseases but is not typically diagnostic.
-
Protein: Normal daily excretion should not exceed 150 mg/24 hours or 10 mg/100 mL.
- Elevation indicates potential renal or cardiac disease; does not detect Bence-Jones globulin.
-
Leukocytes & Nitrites: Positive leukocyte esterase indicates pyuria. Positive nitrite suggests bacteriuria by Gram-negative bacteria.
-
Blood: A positive result indicates potential hematuria from multiple causes.
-
Ketones: Reflect incomplete fat metabolism; associated with diabetes, starvation, and certain conditions.
-
Glucose: Normally absent; presence indicates glycosuria due to elevated serum glucose or specific renal tubular diseases.
-
Bilirubin & Urobilinogen: Bilirubin should not be present; urobilinogen is typically low in healthy individuals and can indicate various diseases based on levels.
Abnormalities in Routine Dipstick Urinalysis
- Urine with pathological abnormalities needs evaluation for fitness.
- "Pathological significance" requires interpretation by medical examiners in collaboration with specialists.
Major Genitourinary Conditions
- Common urinary system disorders reviewed include:
- Urinary calculi
- Hematuria
- Urological infections
- Benign prostatic hyperplasia
Urinary Calculi
- Regulatory guidelines specify investigations for asymptomatic calculi or renal colic history.
- Key considerations include risks of migration and recurrence within the operational environment.
Hematuria
- Hematuria is a frequent diagnosis in urology.
- Asymptomatic microscopic hematuria requires comprehensive evaluation; urine dipstick testing alone is inadequate for diagnosis.
