===Prostatectomy grossing===
There are several consensus papers on grossing prostatectomies by the ''[[International Society of Urological Pathology]]'' (ISUP).
{{Main|Radical prostatectomy}}
*Prostate gland:<ref name=pmid20834234>{{Cite journal  | last1 = Samaratunga | first1 = H. | last2 = Montironi | first2 = R. | last3 = True | first3 = L. | last4 = Epstein | first4 = JI. | last5 = Griffiths | first5 = DF. | last6 = Humphrey | first6 = PA. | last7 = van der Kwast | first7 = T. | last8 = Wheeler | first8 = TM. | last9 = Srigley | first9 = JR. | title = International Society of Urological Pathology (ISUP) Consensus Conference on Handling and Staging of Radical Prostatectomy Specimens.

**[[Embedding in toto]] is not required.
***A study by Epstein suggests it is reasonable to submit all of the posterior aspect and selected sections from the mid portion.<ref name=pmid11381367>{{Cite journal  | last1 = Sehdev | first1 = AE. | last2 = Pan | first2 = CC. | last3 = Epstein | first3 = JI. | title = Comparative analysis of sampling methods for grossing radical prostatectomy specimens performed for nonpalpable (stage T1c) prostatic adenocarcinoma. | journal = Hum Pathol | volume = 32 | issue = 5 | pages = 494-9 | month = May | year = 2001 | doi = 10.1053/hupa.2001.24322 | PMID = 11381367 }}</ref>
**The prostate should be painted -- to mark the margins.
**Sectioning should be done after fixation.
**The prostate should be weighted after trimming the seminal vesicles.
**The apex of the prostate and the bladder neck should be sliced-off, sagittally sectioned, and submitted separately on edge (to assess the margin).
*Lymph nodes and seminal vesicles (SV):<ref name=pmid20818343>{{Cite journal  | last1 = Berney | first1 = DM. | last2 = Wheeler | first2 = TM. | last3 = Grignon | first3 = DJ. | last4 = Epstein | first4 = JI. | last5 = Griffiths | first5 = DF. | last6 = Humphrey | first6 = PA. | last7 = van der Kwast | first7 = T. | last8 = Montironi | first8 = R. | last9 = Delahunt | first9 = B. | title = International Society of Urological Pathology (ISUP) Consensus Conference on Handling and Staging of Radical Prostatectomy Specimens.

**All lymph nodes should be submitted.

**The base of the SV/prostate junction must be submitted.
***SV does ''not'' have to be [[submitted in total]].
