This article deals with the nephroureterectomy grossing, also the cut-up of nephroureterectomy specimens. These specimens include both a kidney, a ureter and a urinary bladder cuff.
Total nephrectomy specimens (without the ureter) and partial nephrectomy specimens are dealt with separately.
Introduction
Nephroureterectomies are done for urothelial carcinoma of the ureter and/or renal pelvis.
The false positive/negative for tumour rate is reported as high as 2.9%.[1]
Specimen opening
- Paint surface of specimen (optional).
- Take the vascular margins - renal artery and renal vein (both en face) and place in one tissue cassette.
- Open the kidney in the frontal plane (from lateral to medial).
- The cut should go through the renal pelvis.
Protocol
Dimensions, weight and inking:
- Type: nephroureterectomy.
- Laterality: [left / right].
- Weight: ___ grams.
- Size of specimen (superior-inferior, left-right, anterior-posterior): ___ x ___ x ___ cm.
- Ureter (length x diameter): ___ x ___ cm.
- Size of bladder cuff: ___ x ___ cm.
- Renal vein (length x diameter): ___ x ___ cm.
- Renal artery (length x diameter): ___ x ___ cm.
- Adrenal gland: [___ x ___ x ___ cm / not identified].
- Inking of surface: [colour].
- Inking of bladder cuff/resection margin: [colour].
- Size of kidney (superior-inferior, left-right, anterior-posterior): ___ x ___ x ___ cm.
- Perinephric fat (maximal dimension): ___ cm.
Tumour:
- Dimensions (superior-inferior, left-right, anterior-posterior): ___ x ___ x ___ cm.
- Location: [upper pole / lower pole / renal pelvis / ureter].
- Colour: [white / tan / yellow].
- Morphology: [solid / cystic / solid and cystic - with ___ % cystic].
- Friability: [friable / not friable].
- Circumscription: [well circumscribed / indeterminate / infiltrative border].
- Hemorrhage: [present / absent].
- Necrosis: [present / absent].
- Margin: [nearest margin ___, distance ___ cm / positive margin, location ___].
- Extension into perinephric fat: [absent / not identified-pushing border / suspicious / present].
- Extension into the renal parenchyma: [absent / suspicious / present].
- Extension into renal hilar fat: [absent / not identified-pushing border / suspicious / present].
- Extension into renal vein: [absent / suspicious / present].
Other:
- Non-tumour renal parenchyma: [cortex unremarkable / thinned].
- Non-tumour collecting system mucosa: [smooth and regular / granular / irregular / dilated].
- Lymph nodes: [number of lymph nodes with [unremarkable cut surface / tumour] / not identified].
Representative sections are submitted:
- Renal vein margin and renal artery margin (en face).
- Urinary bladder cuff margin (on edge). §
- Urinary bladder cuff.
- Ureter - representative sections. ¶
- Tumour with nearest margin.
- Tumour in relation to perinephric fat. †
- Tumour in relation to renal parenchyma. ††
- Tumour and sinus fat.
- Normal kidney.
- Adrenal gland.
Protocol notes
- § Bladder cuff margin may be done en face.
- ¶ Should be cross sections - not longitudinal sections.
- † This typically upstages to pT4. It is uncommon that the tumour goes through the kidney and into the perinephric fat.
- †† Invasion into the renal parenchyma typically upstages to pT3. This can be difficult to judge on cut-up. If renal parenchymal invasion is not seen grossly at least three sections should be taken. Small tumours are usually submitted in toto.
