Etiology
- drugs
- fecal impaction
- neurologic conditions (neurogenic bladder)
- diabetic neuropathy
- low spinal cord injury
- weakening of the detrusor muscle
- vitamin B12 deficiency
- idiopathic causes
- radical pelvic surgery
Pathology
- bladder contraction of inadequate magnitude &/or duration effects bladder emptying in a normal timespan
- bladder underactivity may cause overdistension of the bladder, resulting in overflow incontinence
Diagnostic procedures
- measurement of postvoid residual in men (prior to medication discontinuation)[1]
- postvoid residual <= 450 mL is not suggestive of longstanding urinary retention with bladder atony[1]
- urodynamic studies
Management
- self intermittent catherization
- intraurethral valve pump[2]
- sacral nerve stimulation may be effective[3]
- also see overflow incontinence
