Always get checked for kidney stones, bladder infection, bladder cancer. Drinking water may not stop bleeding but diluted boos so you cannot see it.

Bleeding at the end of urination is likely a bladder or urethra problem. US cannot detect the problem with urethra and early bladder lesion. You need to see urologist for a cystoscopic exam (using a device to look into the urethra and bladder)
