Thanks for your query.Based on the fact that you have posted it appears that you have retention of urine due to Neurogenic Bladder
.In any neurological disorder Bladder is the first organ to get affected and last to get recovered.It takes long time for recovery.It will be better if you get catheterised to drain the bladder continuously.
In view of the long duration required for recovery i would suggest you to drain Bladder through supra pubic Cauterization
(SPC) rather than putting a catheter through Urethra
which is cumbersome and painful.
Consult qualified Urologist
for further management.
