== TNM staging of Urethral Carcinoma (AJCC 8th edition§) ==

=== Prostatic urethra ===

* '''pTX''': cannot be assessed
* '''pT0''': no evidence of primary tumor
* '''pTa''': non-invasive papillary carcinoma
* '''pTis: carcinoma in situ of the prostatic urethra, periurethra or ducts'''
** '''Tis pu: Carcinoma in situ, involvement of prostatic urethra'''
** '''Tis pd: Carcinoma in situ, involvement of prostatic ducts'''
* '''pT1:''' invasion of prostatic urethral '''subepithelial connective tissue'''
* '''pT2: invasion of prostatic stroma'''
** '''In the bladder cancer TNM staging system, only patients with prostatic stromal invasion, either direct or indirect, are considered to have T4a-staged bladder cancer disease'''
** '''Extension of the tumor into the prostatic urethra without stromal invasion is currently classified under the prostatic urethral section, not bladder'''
* '''pT3''': '''invasion of peri-prostatic fat or bladder neck (extraprostatic extension)'''
* '''pT4''': invasion of adjacent organs (example: bladder wall, rectal wall)

=== Penile urethra ===

* '''pTX''': cannot be assessed
* '''pT0''': no evidence of primary tumor
* '''pTa''': noninvasive papillary carcinoma
* '''pTis''': carcinoma in situ
* '''pT1''': invasion of urethral subepithelial connective tissue
* '''pT2''': invasion of corpus spongiosum
* '''pT3''': invasion of corpus cavernosum
* '''pT4''': invasion of adjacent organs (example: bladder wall)
