There will be two types of epithelium in the urethra. Transitional epithelium is the proximal epithelium (uroepithelium). Near the basement membrane, these cells seem columnar, but as they approach the lumen, they become more rounded and dome-shaped.
Transitional epithelium tissue lines the urinary bladder and can expand extensively to handle huge amounts of urine. The underlying tissues are likewise protected by the transitional epithelium from acidic or alkaline urine.
The ureter (one for each kidney) is a long, straight tube with a muscular wall. This tube’s epithelium is stratified, transitional epithelium.
