Hi.i have hemoturia, no pain, had ultrasound and it said nothing wrong, took all test and still nothing.whats wrong, and is it from masturbating daily ?

Cystoscopy : Painless hematuria with normal labs will likely require a cystoscopy. Do not assume it is due to masturbation.

Possible stone: Kidney stones can be a cause for hematuria, although tumors of the kidney and bladder can also cause hematuria. Small stones and not all tumors may be seen on ultrasound. Ask your physician if a ct of the abdomen and pelvis may be helpful. Masturbation is likely unrelated.
