Definition

Noun: 1. Nonspecific urethritis: A medical condition characterized by inflammation of the urethra where the specific causative agent (such as a specific bacterium like Chlamydia trachomatis or Neisseria gonorrhoeae) is not identified through standard testing. It is a diagnosis of exclusion.

Usage
  • Noun:
    • The patient was diagnosed with NSU after tests for gonorrhea and chlamydia came back negative.
    • NSU is a common cause of urethral discharge and discomfort in men.
Advanced Usage
  • Clinical Context: In medical terminology, "NSU" is often used interchangeably with "non-gonococcal urethritis" (NGU), though NGU is a broader category. NSU specifically implies the cause is unknown or nonspecific.
    • The doctor explained that NSU, while uncomfortable, is typically treatable with a course of antibiotics.
Variants and Related Words
  • NGU (Non-Gonococcal Urethritis) (n): A broader term for urethritis not caused by gonorrhea, which includes cases with known causes (e.g., chlamydia) and unknown causes (NSU).
  • Urethritis (n): The general medical term for inflammation of the urethra.
Synonyms
  • Nonspecific urethritis (n): The full form of the abbreviation.
  • Non-gonococcal urethritis (NGU) (n): A closely related, often overlapping term.
Notes
  • Abbreviation: "NSU" is an initialism for "Nonspecific Urethritis." It is primarily used in medical and clinical contexts.
  • Diagnosis: It is important to note that NSU is a diagnosis made after excluding other specific infections. Advances in testing may reclassify some NSU cases as having a specific cause.
Noun
  1. inflammation of the urethra of unknown cause
