My 4month old baby boy have problem in passing urine in the morning which I noticed on23 /03/2015.Doctor suggested urine culture which was reported normal. On 29/03/15 he had fever in the morning (100.4F).Doctor asked to admit my baby . After admission initially he was started on IV antibiotics and supportive management and vitals were monitored. of initial investigation were all within normal limits. USG KUB was done which showed thickened urinary bladder wall. But urine routine examination and culture were sterile. USG KUB was reviewed, there was no posterior urethral dilation and complete voiding of urinary bladder-not suggestive of posterior urethral valve. He was discharged on 3/04/2015. Syr. TAXIM-O (50gm/5ml)3.5 ml orally twice daily for 5 days is given. But still he is uncomfortable in passing morning urine. During the day he passes urine without any uncomfortability but frequent and less in amount.
