Why always burning sensation of urethra but getting relief only after ejaculation which is not painful ? But suffers again after 24 hours continuously. Growth of Staphylococcus aureus is detected in seminal fluid. Earlier growth of Escherichia coli was detected. Many urologists suggest chance of contamination in sample. But no growth of organism found in urine sample everytime. Everytime growth of Staphylococcus aureus or Escherichia coli or Klebsiella pneumoniae detected even semen sample is collected with full care. Proper medication of cotrimoxazol, linezolid, augmentin duo 1 gm as per sensitivity test and advice of concerned urologist. He is also unable to plan further treatment. Nothing found wrong in repeated cystoscopy. Kindly analyse with comments.
