I am unable to pass urine sometimes and other times only in spurts. i can not pass urine normaly.

See a urologist.: There are many reasons you could be having difficulty voiding. It can be difficult to tell if the problem is the bladder's ability to empty efficiently, or if there is obstruction of urine outflow. A urologist will be able to take an inventory of all your voiding complaints & assess the situation. Your urine flow rate may also be measured in the office. Seek help, there are many good treatments.
