A 66-year-old man arrived at an emergency department with sudden penile pain after catching his Foley catheter in the shower. He was not there about the color of anything.
On examination, clinicians found something that demanded an explanation. He had two separate urinary drainage systems in place. The Foley catheter running from his bladder was draining ordinary yellow urine. The percutaneous nephrostomy tube draining his left kidney was filling its bag with purple.
