Document Summary
Loss of structural support of the bladder neck and urethra. Associated with vaginal childbirth, obesity, menopause (low estrogen), and advanced age: cystitis, stones, cancer. Loss of bladder inhibition: stroke, parkinson disease, spinal cord injury. Impaired detrusor activity: diabetic neuropathy (neurogenic bladder, multiple sclerosis, spinal cord injury. The bladder is full and it"s spilling over . Involuntary detrusor contractions occurs during activities that cause cause: Frequent leakage of small amounts of urine associated with urinary retention. increased intra-abdominal pressure: Coughing, laughing, sneezing, physical activity (running, walking, rising from a chair, bending over) Sudden rapid loss of the entire contents of the bladder. Q-tip (cotton swab) test: demonstrates urethral hypermobility by seeing a change in the angle of the q-tip of more than 30 during the valsalva maneuver. Neurologic lesions may cause => absence of the bulbocavernosus reflex.
