Abstract:
In this review, we will discuss and illustrate the pathophysiology, presentation, and multidetector computed tomography findings associated with emergent bladder conditions, limiting our discussion to traumatic, infectious, and obstructive etiologies. After reviewing computed tomography cystographic technique, the commonly utilized classification systems for bladder trauma will be presented with illustrative examples of associated typical and more infrequent secondary injuries and complications. Next, the pathogenesis and imaging appearance of both mechanical and neurogenic acute urinary retention will be addressed, including less common though potentially pathognomonic obstructive etiologies including urethral calculi and ectopic ureteroceles. Finally, we will review and illustrate the imaging features of both inflammatory and infectious cystitis, including hemorrhagic and emphysematous variants, as well as the potentially encountered secondary complications.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Pancreatitis I: Introduction
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:
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
