EMT: Acute GU Emergencies
This lesson focuses on acute genitourinary (GU) emergencies. These conditions often present with abdominal or flank pain and can range from uncomfortable to life-threatening. A key role for the EMT is to assess the patient to identify potential life threats, manage symptoms such as pain, and transport the patient to an appropriate facility. It is important to approach these calls with sensitivity and professionalism.
Understanding Abdominal Pain in GU Emergencies
Pain is a common feature of acute GU emergencies. Understanding the different types of pain can provide clues to the underlying cause.
Visceral Pain: This pain originates from the organs themselves. It is often described as dull, crampy, or achy and is usually poorly localized.
Somatic Pain: This pain arises from irritation of the peritoneal lining. It is typically sharp, constant, and well-localized to a specific area.
Referred Pain: This is pain that is felt in a location other than its origin. For example, a kidney stone can cause flank pain that radiates to the groin.
EMTs should recognize that pain is a subjective experience. While a patient's description of pain is important, it is the provider's responsibility to perform a thorough assessment and not to make assumptions about the severity of the patient's condition based on their own perceptions.
Common Acute GU Emergencies
Urinary Tract Infections (UTIs)
Pathophysiology: An infection in any part of the urinary system, but most commonly in the bladder (cystitis) and urethra. If left untreated, the infection can ascend to the kidneys, causing a more serious condition called pyelonephritis.
Signs and Symptoms: Frequent and painful urination, a persistent urge to urinate, cloudy or strong-smelling urine, and lower abdominal pain. In pyelonephritis, patients may also have fever, flank pain, and nausea/vomiting.
Management: Primarily supportive care. While UTIs are not typically a prehospital emergency, patients with signs of systemic infection (sepsis), such as fever, tachycardia, and hypotension, require rapid transport.
Kidney Stones (Renal Calculi)
Pathophysiology: Hard deposits made of minerals and salts that form inside the kidneys. Pain occurs when a stone passes into the ureter, causing an obstruction.
Signs and Symptoms: The hallmark is severe, colicky (wave-like) flank pain that often radiates to the groin. Patients are often restless and unable to find a position of comfort. Hematuria (blood in the urine) is also common.
Management: Focuses on pain management (within the EMT scope, this is primarily supportive) and transport. While intensely painful, kidney stones are not usually life-threatening unless they cause a complete obstruction and subsequent kidney damage.
Acute Urinary Retention
Pathophysiology: The inability to empty the bladder, leading to distention and severe lower abdominal pain. It is common in older men with an enlarged prostate (benign prostatic hyperplasia).
Signs and Symptoms: Severe lower abdominal pain and tenderness, and a palpable, distended bladder.
Management: Position of comfort and transport. Definitive treatment involves catheterization to drain the bladder.
Assessment and Management Principles
The prehospital care for acute GU emergencies focuses on recognizing life threats, managing pain, and providing transport.
Primary Assessment (ABCs): Ensure a patent airway, adequate breathing, and circulation. While many GU emergencies are not immediately life-threatening, conditions like a ruptured ectopic pregnancy or a severe infection can lead to shock.
History (SAMPLE & OPQRST): A thorough pain assessment is critical. Ask about the onset, quality, radiation, and severity of the pain. Inquire about urinary symptoms, fever, nausea, and vomiting. For female patients of childbearing age, always consider the possibility of pregnancy.
Physical Exam: Palpate the abdomen to assess for tenderness, rigidity, and a distended bladder. Note the patient's general appearance and skin signs.
Supportive Care: Allow the patient to find a position of comfort. Provide emotional support and reassurance.
Transport: Transport the patient to an appropriate facility for further evaluation and treatment.
Critical Thinking Questions
A 45-year-old male presents with a sudden onset of severe, 10/10 right flank pain that comes in waves and radiates to his testicle. What is the most likely diagnosis, and what supportive care measures can you provide?
You are assessing an elderly female in a nursing home who is confused and has a fever. The nursing staff reports she has been complaining of painful urination. Why should you have a high index of suspicion for sepsis in this patient?
Explain the difference between visceral and referred pain, and provide an example of each that might be encountered in a patient with a GU emergency.
A patient is complaining of severe lower abdominal pain and an inability to urinate for the past 12 hours. What physical exam finding would you expect to find?
Why is it important for an EMT to ask a female patient of childbearing age with abdominal pain about her last menstrual period and the possibility of pregnancy?
