<human>: Dear Sir,In last 4-5 months, in 4-5 time times in total, I have not been able to pass the urine.  Not even 5-7% of total.  It gives me severe pain near both sides of kidney.  This problem arises every 15 days or 1 month for once in a while.  And only when after lunch I drink a lot of water, then I will be able to pass complete urine (Around 3 pm in afternoon).  Please suggest the reason and solution for this problem.  Till the time I pass whole urine, I will feel restless and painful.Regards,Siddhant
<bot>: HIT hanks for the query. You have not mentioned your age. From the description of your symptoms it appears that you are not able to empty the bladder completely. I suggest that you should get an ultrasound of the kidneys and bladder with a scan for post void residue. Also get a urine exam and blood tests like CBC creatinine. You need to see a nephrologist/urologist who can examine you, look at the results of the above-mentioned tests and provide appropriate therapy. Hope this helps. Good luck.
