<s>[INST] 3 months ago I have been diagnosed with poststreptococcal glomerulonephritis, microsopic haematuria, urinary tract infection and prostatitis. All of them was cured and the haematuria seemed to get better, but after drinking alcohol there were a lot of blood cells in my urine. Can the alcohol cause this? [/INST] Hello and welcome to HCM.As an Urologist, i must advise you , to stop drinking alcohol, for time being.The main reason is, it can cause, recurrence of your previous problems.You need to get examined by an Urologist and carry out following tests :1. urine routine and culture tests.2. blood routine, sugar, creatinine,LFT, PSA .3. Ultrasound scan of abdomen of and pelvis, with TRUS.(trans rectal ultrasound scan). Drink at least 10 glasses fluids daily.You may send reports to me, as a direct question,for my expert opinion.Dr.Matthew J. Mangat. </s>
