### input:
I took a hard hit in a hockey game last Friday and started urinating a LOT of blood on Sunday. This has continued off and on since then. I also have some nausea and discomfort (off and on). I have a history of kidney stones so I am pretty sure this is not a stone. I was wondering if the hit may have caused a problem that I should go to the doctor for. Thanks.

HI THANKS FOR YOUR QUERY.YOUR RELEVANT CLINICAL HISTORY IS MORE LIKELY TO SUGGEST A INJURY TO "MEMBRANOUS/PROSTATIC URETHRA".THIS MOST LIKE PRESENTS WITH BLOOD IN THE URETHRAL MEATS.OCCASIONALLY ASSOCIATED WITH CONCOMITANT BLADDER INJURIES. I WOULD LIKE TO REMIND YOU THAT STONES DO NOT PRODUCE SUCH DEGREE OF BLOOD FLOW IN THE URINE.ALL YOU NEED TO GET NOW IS AN INVESTIGATION CALLED "INTRAVENOUS PHOTOGRAPHY" WHICH WOULD ACCURATELY DETECT ANY URETHRAL DISCONTINUITY.PARTIAL TEARS WOULD BE TREATED WITH STENTING, COMPLETE TEARS WOULD REQUIRE END TO END REPOSITIONING AND SUTURING.ALL YOU NEED TO DO IS TO KEEP A NOTE ON YOUR URINARY FLOW RATES.CONSULT UROLOGIST IN CASE IF THERE IS SUDDEN CESSATION OF URINATION. ACT ABDOMEN IS ALSO RECOMMEND TO EVALUATE THE CONCOMITANT RENAL STONES."EXTRACORPOREAL SHOCK WAVE LITHOGRAPHY" IS USED TO BREAK STONES.USE ONE AMPULE OF TRANEXIMIC ACID TO CONTROL BLEEDING, THANK YOU.
