A man experienced multiple episodes of macroscopic hematuria following nocturnal exercise. Urinary stones and tumors were considered the two most likely causes. The patient had two hobbies: Consuming health care products in large quantities and engaging in late-night running.
Health care products contain a large amount of calcium phosphate, and we hypothesize that this could induce the formation of small phosphate stones. After exercise, the urinary system is abraded, resulting in bleeding. The patient was advised to stop using the health care products. Consequently, the aforementioned symptoms disappeared immediately. However, the patient resumed the above two habits one year later; correspondingly, the macroscopic hematuria reap
This finding further confirmed the above inference and allowed for a new avenue to determine the cause of the patient’s hematuria.
Core Tip: If patients take a lot of healthcare products containing calcium phosphate, amorphous phosphate crystals may appear in urine. Once they do exercise, they may scratch the urethra and cause hematuria.
