# Uterine Rupture

Suspected uterine rupture requires immediate laparotomy focused on fastest fetal delivery, hemorrhage control, and assessment for repair versus hysterectomy. Prevention centers on informed TOLAC selection, avoidance of third-trimester misoprostol in scarred uteri, and recognition of high-risk uterine scars and pregnancies.

**Clinical question:** How should physicians recognize, stabilize, surgically manage, and reduce the risk of uterine rupture?

## What matters in practice
- Treat suspected intrapartum uterine rupture as an operative emergency: expedite delivery while simultaneously preparing for major hemorrhage and possible hysterectomy. [20]
- A full-thickness rupture at a prior hysterotomy can expose the amniotic sac or uterine contents to the peritoneal cavity; severe cases may involve fetal or placental extrusion. [20]
- For a scarred uterus undergoing labor, avoid misoprostol in the third trimester because ACOG guidance cited in the literature recommends against its use. [4]
- At laparotomy, reapproximate a repairable rupture as a hysterotomy; proceed to hysterectomy when repair is unsafe or bleeding cannot be controlled. [20]
- Uterine rupture risk is higher with more than one prior cesarean; a review reports a 1.59% rate among VBAC-2 patients. [8]

## Manage suspected uterine rupture as an immediate operative emergency

Do not delay operative delivery for confirmatory imaging when rupture is clinically suspected.

Activate obstetric hemorrhage and urgent laparotomy pathways immediately. The operative priority is expeditious neonatal delivery to reduce hypoxic injury and maternal blood loss. When urgency precludes routine preparation, general endotracheal anesthesia and rapid abdominal preparation may be necessary; administer antibiotic prophylaxis when feasible, including after delivery if preincision dosing would delay delivery. [20]

Simultaneously prepare for hemorrhagic shock: obtain large-bore intravenous access, send blood for transfusion preparation, and activate a massive transfusion protocol when hemorrhage is substantial or anticipated. Uterine rupture is associated with hemoperitoneum, hemorrhagic shock, emergent peripartum hysterectomy, and fetal or neonatal hypoxic injury or death. [20]

At entry, prioritize delivery over extensive adhesiolysis. Divide only adhesions that prevent fetal delivery, then inspect the uterus, broad ligaments, bladder region, and other maternal anatomy for extension or associated injury; secure bleeding and repair identified injuries. [20]
- Proceed directly to urgent laparotomy for suspected rupture with maternal compromise, fetal concern, or intrapartum clinical deterioration; the operative goal is delivery plus hemorrhage control, not diagnostic confirmation. [20]
- Use uterine repair only when the defect can be safely reapproximated and hemostasis is achievable. [20]
- Perform hysterectomy for uncontrolled bleeding or when the uterus cannot be safely repaired. [20]
- Anticipate transfusion and escalation to massive transfusion support in major blood loss. [20]

*Operative priorities in suspected uterine rupture. [20]*

| Operative phase | Required action | Decision consequence |
| --- | --- | --- |
| Before incision | Mobilize anesthesia, blood products, and operative team; expedite abdominal preparation and use general endotracheal anesthesia when speed is required. [20] | Limits delay to delivery and prepares for hemorrhage. [20] |
| Abdominal entry | Perform only adhesiolysis necessary to reach and deliver the fetus. [20] | Avoids time-consuming dissection before delivery. [20] |
| After delivery | Inspect uterine defect and adjacent maternal anatomy; control hemorrhage and repair injuries. [20] | Determines feasibility of uterine preservation. [20] |
| Definitive hemostasis | Reapproximate a repairable defect; perform hysterectomy when repair is unsafe or bleeding is excessive. [20] | Achieves durable hemorrhage control. [20] |

## Distinguish complete rupture from dehiscence and define the defect before repair

The operative finding determines urgency, repairability, and counseling.

A clinically consequential uterine rupture is a full-thickness disruption, commonly occurring through a preexisting hysterotomy area weakened by myometrial dehiscence or thinning under contractile tension. The amniotic sac or uterine contents may become exposed to the abdominal cavity; in severe rupture, the fetus or placenta may be expelled into the abdomen. [20]

Document the rupture site, extent, tissue quality, associated hemorrhage, and involvement of adjacent structures before selecting repair or hysterectomy. Uterine preservation is reasonable only when the defect can be safely reapproximated and bleeding is controllable; inability to safely repair or excessive bleeding is an indication for hysterectomy. [20]

Registry-based studies can misclassify partial ruptures or uterine dehiscence as rupture when diagnosis relies on ICD coding. In clinical care, base management on operative anatomy and maternal-fetal consequences rather than coding terminology alone. [3]
- Full-thickness scar disruption with exposure of uterine contents to the peritoneal cavity supports true rupture. [20]
- A finding of myometrial thinning or partial separation without the described full-thickness disruption should not be assumed to carry the same acute clinical consequences as complete rupture. [3][20]
- Extension into adjacent anatomy, uncontrolled bleeding, or nonrepairable tissue shifts management toward hysterectomy. [20]

*Anatomic findings that change surgical management. [3][20]*

| Finding | Clinical interpretation | Next action |
| --- | --- | --- |
| Full-thickness defect with peritoneal exposure of amniotic sac or uterine contents | Complete uterine rupture. [20] | Expedite delivery, control hemorrhage, inspect associated injury, then repair or perform hysterectomy. [20] |
| Fetus or placenta expelled into abdomen | Severe rupture with high fetal and maternal risk. [20] | Immediate delivery and definitive hemorrhage control. [20] |
| Repairable defect with hemostasis achievable | Uterine preservation may be feasible. [20] | Reapproximate the rupture as a hysterotomy and confirm hemostasis. [20] |
| Unsafe repair or excessive bleeding | Uterine preservation is not reliable. [20] | Proceed to hysterectomy for hemostatic control. [20] |

## Reduce rupture risk during trial of labor after cesarean

Counseling should separate likelihood of VBAC from the low-frequency but high-consequence risk of rupture.

For patients considering TOLAC, discuss both the chance of vaginal delivery and scar-related risk. Large studies summarized in a review report vaginal delivery success rates of 60% to 77% among TOLAC populations; the same review reports uterine rupture in 1.59% of patients attempting VBAC after two prior cesareans. [8]

Labor management is a modifiable risk domain. Third-trimester misoprostol should not be used for induction or cervical ripening in a patient with a uterine scar; literature citing ACOG guidance recommends against this practice because of reported ruptures. [4]

Induction-related risk estimates require careful interpretation because induction approach, oxytocin exposure, and cervical status affect both labor outcomes and rupture risk. In a cohort summarized in NICE evidence tables, among women with one prior cesarean and no prior vaginal delivery, vaginal birth occurred in 51% of induced labors versus 64.7% of spontaneous labors. [24] A recent population cohort also notes that unavailable oxytocin dose and duration data limit interpretation of associations between labor management and rupture. [3]
- Do not use misoprostol in the third trimester for induction in patients with a uterine scar. [4]
- When counseling a patient with two prior cesareans, incorporate the reported 1.59% VBAC-2 rupture rate rather than presenting TOLAC risk as equivalent to one prior cesarean. [8]
- For induced TOLAC, document the indication, cervical assessment, induction method, and oxytocin exposure because these variables alter interpretation of labor progress and adverse-event risk. [3][24]

### Patients outside the usual prior-low-transverse-cesarean pathway

Do not restrict rupture risk assessment to cesarean history. Case-based literature identifies prior hysteroscopic surgery and other non-cesarean uterine procedures as potential settings for rupture during pregnancy; reported risk contexts include prior uterine instrumentation, laparoscopic myomectomy, congenital uterine anomalies, connective-tissue disorders, placental abnormalities, malpresentation, and uterotonic exposure. [13]

A pregnancy implanted in a cesarean scar requires a distinct management pathway rather than TOLAC counseling. Patients declining treatment of cesarean scar ectopic pregnancy should be counseled about placenta accreta spectrum, massive hemorrhage, uterine rupture, severe maternal morbidity, and possible maternal death; SMFM recommends repeat cesarean delivery at 34 0/7 to 35 6/7 weeks with antenatal betamethasone before medically indicated late-preterm delivery. [21]
- Obtain and review the operative history for hysteroscopic surgery, myomectomy, and other uterine procedures when a patient presents with pain, labor complications, or unexplained hemoperitoneum. [13]
- For ongoing cesarean scar ectopic pregnancy, plan care with high suspicion for placenta accreta spectrum and schedule repeat cesarean delivery at 34 0/7 to 35 6/7 weeks. [21]

*Risk-management branches for pregnancies with a uterine scar or other uterine injury. [4][8][13][21][24]*

| Clinical branch | Risk discriminator | Management implication |
| --- | --- | --- |
| One prior cesarean considering TOLAC | Reported TOLAC vaginal delivery success is 60% to 77% across large studies. [8] | Use individualized counseling that addresses both probability of VBAC and rupture consequences. [8] |
| Two prior cesareans considering VBAC | Reported rupture rate is 1.59% in VBAC-2 patients. [8] | Counsel separately from one-prior-cesarean risk discussions. [8] |
| Scarred uterus requiring cervical ripening or induction | Misoprostol has been associated with reported ruptures; cited ACOG guidance recommends against third-trimester use in a uterine scar. [4] | Avoid misoprostol. [4] |
| Induced rather than spontaneous TOLAC | In one cited cohort without prior vaginal birth, VBAC was 51% with induction versus 64.7% with spontaneous labor. [24] | Discuss lower observed vaginal-delivery probability and document induction approach. [24] |
| Cesarean scar ectopic pregnancy continued expectantly | Risk includes placenta accreta spectrum, massive hemorrhage, rupture, severe morbidity, and maternal death. [21] | Plan placenta accreta spectrum-oriented surveillance and repeat cesarean at 34 0/7 to 35 6/7 weeks if pregnancy is continued. [21] |

## Complete hemostatic and injury assessment after delivery

Post-delivery management is driven by bleeding severity and the extent of associated injury.

After delivery and uterine assessment, continue systematic inspection for maternal injury and persistent bleeding. Complex cesarean surgical guidance specifies careful inspection of maternal anatomy, control of all bleeding, and repair of identified injuries; transfusion support, including massive transfusion protocol activation, may be required. [20]

A minimally invasive approach is not the default acute strategy. A 2025 report proposes laparoscopic repair only for hemodynamically stable patients with minor rupture after spontaneous delivery; this selective approach does not replace emergency laparotomy when urgent delivery, active major hemorrhage, or unstable physiology is present. [11][20]
- Reassess for ongoing intraperitoneal bleeding after uterine closure or hysterectomy. [20]
- Escalate transfusion support when hemorrhage requires it; do not defer blood-product mobilization until after the operative defect is fully characterized. [20]
- Consider laparoscopic repair only in a hemodynamically stable patient with a minor postpartum rupture after spontaneous delivery, recognizing that the evidence is a proposed technique from limited literature. [11]

*Post-delivery choices after uterine rupture. [11][20]*

| Clinical condition | Preferred approach | Rationale |
| --- | --- | --- |
| Active major hemorrhage, unstable physiology, or need for immediate fetal delivery | Open emergency operative management with delivery, hemostasis, and repair or hysterectomy. [20] | Minimizes delay and permits definitive hemorrhage control. [20] |
| Repairable uterine defect with controlled bleeding | Uterine reapproximation as for a hysterotomy. [20] | Preserves the uterus when safe repair is feasible. [20] |
| Nonrepairable defect or excessive bleeding | Peripartum hysterectomy. [20] | Provides hemostatic control when repair is unsafe. [20] |
| Hemodynamically stable patient with minor rupture after spontaneous delivery | Selected laparoscopic repair may be considered. [11] | This approach has been proposed for a narrowly selected postpartum population. [11] |

## Document the rupture precisely to guide future obstetric decisions

Operative detail is necessary because future rupture assessment depends on the prior uterine injury.

The operative report should record the anatomic site and extent of the rupture, whether it was full thickness, whether fetal or placental extrusion occurred, repair technique or hysterectomy, estimated hemorrhage, transfusion, and associated bladder or other maternal injury. These findings distinguish a true rupture from lesser scar disruption and provide the data needed for future pregnancy counseling. [3][20]

For patients whose rupture followed a non-cesarean uterine procedure, include the antecedent procedure in discharge documentation. Pregnancy-associated rupture has been reported after hysteroscopic procedures and in the setting of prior laparoscopic myomectomy, where prior surgical details may materially affect future risk assessment. [13]
- Do not use an ICD diagnosis alone to characterize severity; operative anatomy should define the event because coding may include dehiscence or partial rupture. [3]
- Ensure the patient receives a copy of the operative report when uterine preservation is performed, because future clinicians need the rupture location and repair details. [20]
- After hysterectomy, document the indication as nonrepairable rupture or uncontrollable hemorrhage when applicable. [20]

*Minimum operative documentation after suspected or confirmed rupture. [3][20]*

| Element | Why it changes subsequent care |
| --- | --- |
| Full-thickness rupture versus dehiscence or partial defect | Prevents severity misclassification from registry or coding terminology. [3] |
| Location, dimensions, and extension of uterine defect | Defines the prior uterine injury for future obstetric risk assessment. [20] |
| Fetal or placental extrusion and associated maternal injury | Captures severity and informs future counseling. [20] |
| Repair feasibility, repair performed, or hysterectomy | Documents whether uterine preservation was possible and why definitive surgery was required. [20] |
| Hemorrhage and transfusion requirement | Records acute severity and perioperative resource needs. [20] |

## Common questions

### Can uterine rupture be managed laparoscopically?

Only in highly selected circumstances: a proposed laparoscopic technique targets hemodynamically stable patients with a minor rupture after spontaneous delivery. Suspected intrapartum rupture requiring fetal delivery or hemorrhage control requires urgent open operative management. [11][20]
