Diagnosis and Management of Overflow Incontinence

Diagnostic Evaluation

Post-void residual (PVR) measurement is essential for patients with suspected overflow incontinence, with elevated PVR (typically >250-300 mL) suggesting overflow incontinence, according to the American Urological Association 1
Urinalysis should be performed to rule out urinary tract infection and hematuria, as recommended by the American Urological Association 2
Careful physical examination, including abdominal, rectal/genitourinary exam, is necessary to identify possible causes of obstruction, as suggested by the American Urological Association 1

Antimuscarinic medications used for overactive bladder should be avoided or used with extreme caution in patients with elevated PVR (>250-300 mL) as they may worsen retention, according to the American Urological Association 1
Indwelling catheters should be avoided except as a last resort due to high risk of urinary tract infections, urethral erosion, and urolithiasis, as warned by the American Urological Association 3
When intermittent catheterization is required, patients must be willing and able to perform the procedure or have caregiver support, as emphasized by the American Urological Association 3

Regular assessment of treatment efficacy and side effects is necessary, as recommended by the American Urological Association 4
Monitoring of post-void residual volumes is essential to ensure improvement, according to the American Urological Association 1
Reassessment is necessary if treatment goals are not met, as suggested by the American Urological Association 5

Misdiagnosing overflow incontinence as overactive bladder can lead to inappropriate treatment with antimuscarinics, potentially worsening the condition, as cautioned by the American Urological Association 1
Failure to measure post-void residual in patients with incontinence may miss this diagnosis, as warned by the American Urological Association 1
Not considering medication side effects as potential contributors to overflow incontinence is a common pitfall, as noted by the American Urological Association 1
