Hi, This problem is actually faced by my father who is 65 yrs old. It occurred in Nov 2012. When he was trying to move some heavy box there was slight pain in his lower back, which he ignored that time. When he got up next morning there was severe pain in his lower back and he was not able to move at all. There was numbness in his lower body he was not able to feel when he wanted to pass the urine or stools. Doctors said that he needs to be operated and the pressure has to be released from his nerve so that he can feel the movement in his limb, however there was no guarantee of survival, so we didn't get him operated and with the help of physiotherapy we tried curing it... Within 4-5 months he got control over his stools but he still not able to pass the urine on its own (we have put catheter). Now a urologist have suggested for urodynamic test which can help us stating if it will be safe to remove the catheter. Can you please guide me for the same.
