Overflow incontinence

Clinic

• It is involuntary release of urine from an overfull urinary bladder, often in the absence of any urge to urinate.
• Overflow incontinence occurs when the patient's bladder is always full so that it frequently leaks urine.
• This condition occurs
  1. In people who have a blockage of the bladder outlet (BPH, prostate cancer, or narrowing of the urethra)
  2. When the muscle that expels urine from the bladder is too weak to empty the bladder normally.
  3. A side effect of certain medications.

Causation

Non-Miasmathic

• Lesions affecting sacral segments or peripheral autonomic fibres result in atonic bladder with loss of sphincteric coordination. This results in loss of detrusor contraction, difficulty in starting urination and overflow incontinence.
• Tumors (Fibroid or Ovarian tumors)
• Kidney stones that block the urethra
• Benign prostatic hyperplasia
• Advanced vaginal prolapse

Miasmathic

• Autonomic neuropathy from diabetes or other diseases (e.g. Multiple sclerosis) can decrease neural signals from the bladder (allowing for overfilling) and may also decrease the expulsion of urine by the detrusor muscle (allowing for urinary retention).
• Nervous system disorders are additional causes of overflow incontinence.
