Acathectic

Definition & Etymology

Acathectic (adjective): Characterized by the inability to retain bodily secretions, particularly feces or urine. The term describes a state of incontinence resulting from a failure of a sphincter or physiological reservoir to hold its contents. It signifies a loss of the normal retentive function of an organ. (From Greek a-, ‘without’ + kathexis, ‘retention’).

Clinical Significance

In clinical practice, acathexis is not a disease but a significant symptom indicating an underlying pathology. It points to a failure in the complex neuromuscular mechanisms responsible for continence, such as impaired sphincter tone, nerve damage (e.g., to the pudendal nerve), or loss of muscular control in the pelvic floor. The term highlights the functional deficit of a retaining organ, most commonly the rectal ampulla or the urinary bladder. Assessing the nature of the acathectic state is crucial for diagnosing the root cause, which can range from neurological disorders to direct structural trauma. It is a fundamental concept in understanding the pathophysiology of incontinence.

Related Conditions

The state of being acathectic is a core feature of various forms of incontinence. It is most commonly associated with fecal incontinence (anal incontinence) and urinary incontinence. Underlying causes frequently include neurological conditions like cauda equina syndrome, spinal cord injury, multiple sclerosis, or stroke. It may also result from direct anatomical damage to the internal or external anal sphincters or pelvic floor muscles, often due to obstetric trauma during childbirth, anorectal surgery, or age-related sarcopenia.

Key Takeaways

• Refers to the pathological inability to retain bodily secretions due to a failure of a retaining mechanism.
• It is a symptom, not a diagnosis, that points toward sphincter, muscular, or neurological dysfunction.
• Primarily associated with fecal and urinary incontinence stemming from a wide range of neurological or structural causes.
