Hysterectomy techniques and indications

✂️ The Uterus Exit

• Indications:
  • Benign: Symptomatic fibroids, abnormal uterine bleeding (AUB), endometriosis, pelvic organ prolapse.
  • Malignant: Endometrial, cervical, or ovarian cancers.
• Types & Approaches:
  • Total (TAH/TVH/TLH): Uterus + cervix removed. Vaginal (TVH) is preferred when feasible.
  • Subtotal/Supracervical: Uterus only.
  • Radical: For cancer; includes parametrium & upper vagina.
  • Laparoscopic/Robotic approaches offer minimal invasion.

⭐ Ureteral injury is a major complication, especially during uterine artery ligation. 📌 Mnemonic: "Water (ureter) under the bridge (uterine artery)."

🏥 Management - When to Evict

• Benign Indications (Definitive Tx):
  • Symptomatic Leiomyomas (Fibroids): Most common reason.
  • Abnormal Uterine Bleeding (AUB): When medical/procedural management fails.
  • Adenomyosis / Endometriosis: For severe, refractory pain or bleeding.
  • Pelvic Organ Prolapse: When uterus descends into the vagina.
• Malignant Indications:
  • Primary treatment or staging for endometrial, cervical, and some ovarian cancers.
• Obstetric Emergencies:
  • Intractable postpartum hemorrhage; placenta accreta spectrum disorders.

⭐ Always consider and exhaust less invasive options (medical, IUD, ablation) before hysterectomy for benign conditions.

🗺️ Anatomy - Know the Neighborhood

• Key Structures at Risk:

  • Ureter: Most common site of injury is at the level of the uterine artery or near the uterosacral ligaments.
  • Bladder: Anterior to uterus.
  • Rectum: Posterior to uterus.

• Vascular Supply:

  • Uterine Artery: Branch of the internal iliac artery.
  • Ovarian Artery: Branch of the abdominal aorta.

• Ligamentous Support:

  • Cardinal (Transverse Cervical) Ligament: Contains uterine vessels.
  • Uterosacral Ligaments: Anchor cervix to sacrum.

⭐ "Water under the bridge": The Ureter (water) passes inferior to the Uterine Artery (bridge) approximately 2 cm lateral to the cervix. This is a critical landmark to prevent iatrogenic injury.

🔪 Hysterectomy: Techniques & Indications

• Indications:
  • Malignancy: Endometrial, cervical, ovarian cancer.
  • Benign (refractory to medical tx): Symptomatic leiomyomas (fibroids), abnormal uterine bleeding (AUB), endometriosis/adenomyosis, pelvic organ prolapse.
• Surgical Approaches:
  • Vaginal (TVH): Preferred route; least invasive, fastest recovery. Best for non-malignant, smaller uterus.
  • Laparoscopic (LAVH/TLH): Minimally invasive alternative to abdominal.
  • Abdominal (TAH): Most invasive; for large uterus (>12-14 wk size), malignancy staging, or severe adhesions.

⭐ Ureter Injury: The ureter is most vulnerable during ligation of the uterine artery ("water under the bridge") and dissection near the cardinal ligament.

⚠️ Complications - Post-Op Pitfalls

• Intra-op: Hemorrhage (uterine artery), ureteric injury, bladder/bowel injury.
• Early Post-op: Infection (vaginal cuff cellulitis/abscess), VTE, ileus.
• Late Post-op: Vaginal vault prolapse, premature ovarian failure (if oophorectomy), urinary incontinence.

⭐ Ureteric injury is most common during ligation of the uterine artery, which passes inferiorly and laterally to it ("water under the bridge").

⚡ Biggest Takeaways

• Uterine fibroids (leiomyomas) are the #1 indication for hysterectomy, followed by abnormal uterine bleeding and malignancy.
• Vaginal hysterectomy is the preferred, least morbid approach, especially with uterine prolapse.
• Abdominal hysterectomy is reserved for very large uteri (>12-14 wks size) or extensive disease.
• Ureteral injury is the most feared complication, especially during uterine artery ligation ("water under the bridge").
• Total hysterectomy removes the uterus and cervix; supracervical spares the cervix.
