BOF 19
The urinary bladder may be involved in many central
and peripheral neurological diseases, all are true, except:
1-the pelvic parasympathetic nerves stimulation causes
bladder emptying
2-The L1 and L2 sympathetic outflow mediates bladder
relaxation
3- S2, 3 and 4 sacral spinal cord lesions cause
urinary retention as opposed to higher lesions which cause hyper excitable
bladder
4-in acute spinal cord trans-section, urinary
retention is rare, but urgency and frequency is much more common
5-neurogenic bladder in paraplegics is at a risk of
future development of urinary bladder cancer
Answer 4
1-hence anticholinergics are given in upper motor
neuron lesion to dampen the bladder.
2-and alpha blockers cause retrograde ejaculation
3-true …..
4-the reverse is true, in acute lesions, retention is
seen early to be followed gradually by urgency and frequency of micturition
5-true, usually squamous in type
