Urinary Catheter

Description. Some highlights:

  • Size: (bore) diameter 6 to 18 Fr, with Fr=0.33mm. Usually 14 or 16 Fr, i.e., 4.62mm or 5.28mm.
  • Balloon size: 5ml or 10ml. More than that (say 30ml) only for special applications (like putting pressure on the prostate after surgery to help it heal).

Excellent paper on the issues with indwelling urinary catheters
