Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations01:26

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Summary

Ureteric colic, a condition typically causing severe pain, can unexpectedly lead to elevated serum amylase levels. This finding suggests a link between urinary extravasation and pancreatic irritation.

Area of Science:

  • Nephrology
  • Gastroenterology
  • Biochemistry

Background:

  • Hyperamylasemia is commonly linked to acute pancreatitis.
  • However, various other clinical conditions can also elevate serum amylase.
  • Ureteric colic has not been previously reported as a cause of hyperamylasemia.

Observation:

  • A 47-year-old woman presented with symptoms suggestive of left ureteric colic.
  • Radiological imaging revealed an upper ureteric stone with associated urinary extravasation.
  • Serum amylase levels were elevated upon presentation but normalized within 24 hours.

Findings:

  • This case report documents hyperamylasemia in a patient with ureteric colic.
  • The elevated amylase levels normalized spontaneously within 24 hours.

Published on: April 25, 2025

  • Urinary extravasation secondary to the ureteric stone is proposed as the cause.

    • Implications:

    • Ureteric colic should be considered as a potential cause of hyperamylasemia.
    • Elevated serum amylase in ureteric colic patients may indicate urinary extravasation.
    • This association warrants further investigation into the mechanism of pancreatic irritation.
