I am concerned because the strength of my urinary flow is decreased well as the amount i am urinating. I drink a lot of water and coffee everyday and urinate quite often. Recently I noticed that I am going several hours without needing to urinate. Sometimes the sensation to urinate dissipates. I am concerned that the urine is refluxing back into my kidneys. I do not have any urinary pain, itching, blood or cloudy urine.
