Isolated Bladder Neck Invasion (IBNI) / Isolated Positive Bladder Neck Margin (IPBNM) Nomogram
This nomogram can be used to predict the probability of IBNI or IPBNM at radical prostatectomy.
Biopsy primary Gleason pattern ≥ 4 | |
Biopsy secondary Gleason pattern ≥ 4 | |
Biopsy longest tumor length, mm | |
Biopsy-transition zone features |
Probability of IBNI or IPBNM at radical prostatectomy | 0% |
