Partial nephrectomy grossing

This article deals with the cut-up of partial nephrectomy for tumour specimens.

Total nephrectomy for tumour specimens are dealt with in the total nephrectomy for tumour article.

Introduction

Partial nephrectomies are done for kidney tumours.

They do not have have any (large) vessels or the any significant part of the collecting system.

Protocol

• Laterality: [left / right].
• Weight: ___ grams.
• Size of specimen (superior-inferior, left-right, anterior-posterior): ___ x ___ x ___ cm.
• Adrenal gland: [___ x ___ x ___ cm / not identified].
• Inking of renal parenchymal margin: [colour].
• Inking other margin: [another 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 / mid / lower pole].
• Colour: [yellow / tan / white].
• 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 ___].
