Main difference between these two is residual volume... In (A) the Pt would unlikely have it...

guys as you can see detrussor instability or hypertonicity is mostly idiopathic or due to irritative problems: tumor, stones, or infection .. this patient has a high residual volumen not typical of a detrussor muscle hyperactivity ..
its not stress incon because there is no strain that have provoke the leak (cough etc ..)
ill go with overflow incontinence due to her residual volumen ..
suggestions?

very simple whenever pt has high residual volume it indicates that some thing more is left in the bladder than usual which is 50 ml normal and when presure rises pt passes small amounts of urine to equalize that pressure...so very simple case of overflow incontinence i did nbme today n this q was in it so i did it right i think hurray

  #8

epidural anesthesia is assoc with overflow incontinence

there is a similar q in uw that says so....
