###Human: I am passing urine with little strain. Why? ###Assistant: Hi.I have some more queries about your complaints. As male urethra is S shaped some urine gets trapped and milking often clears the trapped urine at the end of urination. The complaints you have quoted may fit into one of the below. BPH usually occurs after 50 years, which is not in your case as you are having these for the last 20 years. Recurrent UTI is a consideration which can be ruled out by CUE (cumulative urinary excretion). For strictures and diverticulum you need catheterization to rule out or radiographic evaluation of urethra with contrast like retrograde cystourethrogram and ultrasound. I would advise you to avoid dairy. 1. CUE. 2. Ultrasonography of abdomen with focus on prostate and post volume.
