Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter.

The sizes of the sheath of the rigid cystoscope are 17 French gauge (5.7 mm diameter), 19 Fr gauge (6.3 mm diameter), and 22 Fr gauge (7.3 mm diameter).

The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
