Total nephrectomy for tumour grossing

This article deals with the cut-up of total nephrectomy for tumour specimens. It also includes radical nephrectomy with or without an adrenal gland.

Partial nephrectomy specimens are dealt with separately.

Introduction

Nephrectomies are typically done for kidney tumours.

They come in three basics flavours:

• Partial nephrectomy.
• Nephrectomy.
• Radical nephrectomy - includes Gerota's fascia.
  • Gerota's fascia is the fascia overlying the perinephric fat).

Protocol

• Location: [upper pole / mid / lower pole].
• Colour: [yellow / tan / white].
• Friability: [friable / not friable].
