Urinary Catheter Sizes Chart
A urinary catheter sizes chart is an essential reference tool for healthcare professionals, aiding in the selection of the appropriate catheter size based on patient needs and the clinical situation. Catheters are typically measured using the French (Fr) scale, where one French unit corresponds to approximately 0.33 millimeters in diameter. This chart provides a detailed listing of sizes, allowing clinicians to choose the proper device for optimal urinary drainage while minimizing discomfort and the risk of urethral trauma.
