The urethra takes the urine from the urinary bladder to outside of the body.
It is occasionally afflicited by tumours.
Anatomy
- Proximal portion = urothelium.
- Distal portion = squamous.
Males
- Pre-prostatic urethra - transitional epithelium.
- Prostatic urethra - transitional epithelium.
- Cancer arising at this site is prostatic urothelial carcinoma.
- Membranous urethra (from apex of prostate to bulb of penis (bulb of the corpus spongiosusm)) - pseudostratified columnar epithelium.
- Spongy urethra - pseudostratified columnar epithelium (proximal) & stratified squamous (distal).
Pathology
- Squamous cell carcinoma.
- Urothelial carcinoma.
- Prostatic carcinoma - may have pseudopapillae[1] and mimic urothelial carcinoma - see urothelial carcinoma-like prostatic carcinoma.
- Clear cell adenocarcinoma of the urethra - similar to clear cell carcinoma of the gynecologic tract.
- Urethral caruncle.
