Obstetric Emergency
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.
Time-Critical Management
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. ajogajogSurgical management of complex cesarean delivery
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. ajogajogSurgical management of complex cesarean delivery
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. ajogajogSurgical management of complex cesarean delivery
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. ajogajogSurgical management of complex cesarean delivery
Use uterine repair only when the defect can be safely reapproximated and hemostasis is achievable. ajogajogSurgical management of complex cesarean delivery
Perform hysterectomy for uncontrolled bleeding or when the uterus cannot be safely repaired. ajogajogSurgical management of complex cesarean delivery
Anticipate transfusion and escalation to massive transfusion support in major blood loss. ajogajogSurgical management of complex cesarean delivery

Intraoperative Assessment
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. ajogajogSurgical management of complex cesarean delivery
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. ajogajogSurgical management of complex cesarean delivery
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. NatureNatureUterine rupture risk during trial of labor after one cesarean in a population-based cohort study of induction method and labor management | Scientific Reports
Full-thickness scar disruption with exposure of uterine contents to the peritoneal cavity supports true rupture. ajogajogSurgical management of complex cesarean delivery
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. Nature+1NatureUterine rupture risk during trial of labor after one cesarean in a population-based cohort study of induction method and labor management | Scientific ReportsajogSurgical management of complex cesarean delivery

| Finding | Clinical interpretation | Next action |

Prevention
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. ScienceDirectScienceDirect11 Uterine scar rupture - Prediction, prevention, diagnosis, and ...
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. ScienceDirectScienceDirectUterine rupture associated with misoprostol labor induction in women with previous cesarean delivery - ScienceDirect
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. nice org uknice org uk[PDF] CG70 Evidence tables - NICE A recent population cohort also notes that unavailable oxytocin dose and duration data limit interpretation of associations between labor management and rupture. NatureNatureUterine rupture risk during trial of labor after one cesarean in a population-based cohort study of induction method and labor management | Scientific Reports
Do not use misoprostol in the third trimester for induction in patients with a uterine scar. ScienceDirectScienceDirectUterine rupture associated with misoprostol labor induction in women with previous cesarean delivery - ScienceDirect
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. ScienceDirectScienceDirect11 Uterine scar rupture - Prediction, prevention, diagnosis, and ...

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.

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. ajogajogSociety for Maternal-Fetal Medicine Consult Series #63: Cesarean ...

After Definitive Control
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. ajogajogSurgical management of complex cesarean delivery
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.

Future Pregnancy Planning
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. Nature+1NatureUterine rupture risk during trial of labor after one cesarean in a population-based cohort study of induction method and labor management | Scientific ReportsajogSurgical management of complex cesarean delivery
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.

Do not use an ICD diagnosis alone to characterize severity; operative anatomy should define the event because coding may include dehiscence or partial rupture. NatureNatureUterine rupture risk during trial of labor after one cesarean in a population-based cohort study of induction method and labor management | Scientific Reports
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. ajogajogSurgical management of complex cesarean delivery
After hysterectomy, document the indication as nonrepairable rupture or uncontrollable hemorrhage when applicable. ajogajogSurgical management of complex cesarean delivery

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.
