🎗️ Cervical Cancer Querleu-Morrow Radical Hysterectomy Type
Standardise radical hysterectomy by lateral parametrial resection extent (Querleu-Morrow A/B/C/D), with resection landmarks, nerve handling and typical indications. Instant, browser-side.
The classification is defined by how far laterally the parametrium is resected, replacing the older Piver-Rutledge system.

When to use
Communicate and standardise the radicality of radical hysterectomy for cervical cancer using the Querleu-Morrow classification.
How it works
A minimal (medial to ureter); B at ureteric level (B1 / B2 + paracervical nodes); C at internal-iliac junction (C1 nerve-sparing preferred / C2 non-sparing); D laterally extended pelvic-wall resection (LEER).
Key points
- The classification is defined by how far laterally the parametrium is resected, replacing the older Piver-Rutledge system.
- Type C1 (nerve-sparing) is the preferred standard radical procedure; C2 sacrifices autonomic nerves and causes more voiding/rectal dysfunction.
- Voiding and rectal dysfunction broadly increase from type A through C2.
- The 2017 update reinforced C1 as the preferred type-C operation, reserving C2 for when nerves cannot be spared.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Surgical type | A — minimal resection |
|---|
→Q-M typeType A
- Type：Type A (minimal resection)
- Resection landmark：Paracervix transected medial to the ureter (between cervix and ureter)
- Nerve handling：Autonomic nerves not involved, bladder branches preserved
| Surgical type | D — laterally extended resection (LEER) |
|---|
→Q-M typeType D
- Type：Type D (laterally extended resection)
- Resection landmark：Entire paracervix resected at the pelvic wall (incl. internal iliac vessels; D2/LEER also adjacent fascia/muscle)
- Nerve handling：Nerves sacrificed, resection reaches the pelvic wall
