Partial nephrectomy (nephron-sparing)

6 steps, each one the authored title and caption from the interactive animation, with the frame captured from that step. Read it before the case, or print it and work through the steps in order.

Teaching only, not for diagnosis or treatment decisions. The text on this sheet is the animation's own step copy, reproduced verbatim.

  1. 01

    Read the model

    Partial nephrectomy (nephron-sparing). Step 1: Read the model. Captured frame from the interactive animation.
    • Pre-operative imaging decides this operation: an exophytic upper-pole tumour, depth into the parenchyma, and the arterial branch map.
    • The margin is planned before the clamp goes on.
  2. 02

    Hilum exposed + artery slung

    Partial nephrectomy (nephron-sparing). Step 2: Hilum exposed + artery slung. Captured frame from the interactive animation.
    • The colon is reflected and the renal artery skeletonised enough to clamp it cleanly.
    • The vein is exposed but usually not clamped.
  3. 03

    Clamp + excision

    Partial nephrectomy (nephron-sparing). Step 3: Clamp + excision. Captured frame from the interactive animation.
    • The bulldog closes and the kidney pales: the warm ischaemia clock is running.
    • Cold-scissors excision takes the tumour with a thin visible rim of normal parenchyma.
  4. 04

    Inner layer (renorrhaphy 1)

    Partial nephrectomy (nephron-sparing). Step 4: Inner layer (renorrhaphy 1). Captured frame from the interactive animation.
    • The base is inspected: any opened calyx or vessel is closed with the running inner layer.
    • This layer is what stops a urine leak, and it is closed now, under clamp, not later.
  5. 05

    Outer layer (renorrhaphy 2)

    Partial nephrectomy (nephron-sparing). Step 5: Outer layer (renorrhaphy 2). Captured frame from the interactive animation.
    • A sliding-clip outer layer re-approximates the capsule over a bolster.
    • Haemostasis by compression, designed to hold once the artery reopens.
  6. 06

    Reperfusion + check

    Partial nephrectomy (nephron-sparing). Step 6: Reperfusion + check. Captured frame from the interactive animation.
    • The clamp comes off and colour returns.
    • Watch the bed: a ooze settles with pressure and patience; delayed bleeding days later is a pseudoaneurysm until proven otherwise.

Derived from PartialNephrectomyScene.tsx at build time: every step title and caption above is the authored ProcedureDef text, reproduced verbatim, and this page shares its readable-points renderer with the animation itself. 6 of 6 steps have a captured frame.

Text fingerprint 38fbb7ef1f6b5e95. A caption edit without a re-capture fails the production check, so the sheet and the animation cannot drift apart silently.
