<human>: What causes a string of blood to appear in a foley catheter bag? I have an enlarged prostate and have had the foley tube attached for about 8 days. Am taking 0.4 MG of Flomax. Also notice blood at tip of penis where tube is inserted. No pain involved so far. String of blood or any blood only appears occasionally.
<bot>: Hello welcome to Chat Doctor. Yes. This kind features are seen in long-standing catheterization. There are two reasons I can think of. The enlarged prostate itself can give trace of blood sometimes. The longstanding catheterization in a narrowed urethra when dilated may cause mild injury and cause bleed. After all this you let a doctor see and take action by changing or removing. Need to ask ? Do not hesitate. Thank you.
