From the Guidelines
Urinary incontinence is not typically associated with a T2 compression fracture, and if present, it may indicate a more extensive neurological issue requiring immediate medical attention. A T2 vertebral compression fracture occurs in the upper thoracic spine, which is anatomically distant from the nerves that control bladder function. The nerves controlling urination primarily originate from the sacral region (S2-S4) of the spinal cord, much lower than the T2 level 1.
Key Considerations
- The presence of urinary incontinence with a thoracic fracture could indicate spinal cord compression or injury at multiple levels, a cauda equina syndrome, or another neurological condition affecting bladder control.
- The combination of symptoms warrants urgent medical evaluation, as it may represent a medical emergency requiring prompt intervention to prevent permanent neurological damage.
- Proper diagnosis through imaging studies like MRI and neurological examination is essential for appropriate treatment.
Relevant Evidence
- Studies have shown that lower urinary tract injuries are more commonly associated with pelvic fractures, with posterior urethral injuries occurring in 1.5-10% of pelvic fractures 1.
- The American Urological Association (AUA) guidelines recommend that clinicians may perform primary realignment in hemodynamically stable patients with pelvic fracture-associated urethral injury, but prolonged attempts at endoscopic realignment should be avoided 1.
- The diagnosis of urethral injuries is typically made by retrograde urethrography, and immediate surgical closure is recommended primarily in penetrating injuries of the anterior urethra 1.
Clinical Implications
- If experiencing urinary incontinence along with a T2 compression fracture, seek immediate medical care for proper diagnosis and treatment.
- A thorough evaluation, including imaging studies and neurological examination, is necessary to determine the underlying cause of urinary incontinence and to guide appropriate management.
From the Research
Urinary Incontinence and Spinal Fractures
- The relationship between spinal fractures and urinary incontinence is complex and can involve various mechanisms, including nerve damage and structural changes in the pelvis 2.
- A case report described a patient who developed urinary retention after a sacral fracture, which was attributed to an isolated sacral root injury 3.
- Another study discussed the evaluation and management of stress urinary incontinence following traumatic pelvic injury, highlighting the importance of imaging and urodynamic testing in assessing the nature and severity of incontinence symptoms 4.
Nerve Damage and Urinary Incontinence
- Pudendal nerve entrapment syndrome can cause urinary incontinence, as well as other symptoms such as dysuria and anal incontinence 5.
- Sacral nerve stimulation has been shown to be effective in treating urinary urge incontinence, urgency-frequency, and urinary retention in patients who are refractory to other therapies 6.
- However, the available evidence does not specifically address the relationship between T2 compression fractures and urinary incontinence.
Pelvic Fractures and Urinary Incontinence
- Pelvic fractures can lead to urinary incontinence due to various factors, including malunion of fracture ends and resulting bone spurs 2.
- A study on sacral nerve stimulation for urinary incontinence noted that patients with stress incontinence due to pelvic trauma may require individualized treatment approaches 6.
- The available evidence suggests that pelvic fractures, including those involving the sacrum, can contribute to urinary incontinence, but the specific relationship between T2 compression fractures and urinary incontinence is not well-established 4, 2, 3.
