Hi, I had gone through your question and understand your concerns. In most cases this is sign of uroinfection or kidneys stones. This is mainly self limiting and doesnt require any specific treatment. Less common it indicates possible bleeding in urethra, bladder or kidneys from popped vessel or some other cause. IF this continues he should do urine analysis, urinoculture and kidneys ultrasound to rule these main causes out. You should drink raspberry tea and plenty of water till you do tests. Also,it is necessary to avoid sexual intercourse and have keep good hygiene. He should reduce salt in your diet as well since this could lead to increased risk of urinary stone formation. Some more serious issues such as tumors are less common but in case of permanent bleeding it should be continued. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
