Which of the following is a contraindication for radiofrequency endometrial ablation?

Radiofrequency endometrial ablation is a minimally invasive procedure used to treat abnormal uterine bleeding by destroying the endometrial lining of the uterus. Certain conditions can prevent the successful application of this technique or increase the risk of complications.

Abnormal uterine shape is indeed a contraindication for radiofrequency endometrial ablation because the geometry of the uterus can affect how evenly the ablation is performed. If the uterus is misshapen due to conditions such as fibroids, polyps, or congenital abnormalities, the procedure may not achieve uniform ablation of the endometrial tissue. This lack of uniformity can result in incomplete treatment, leaving behind tissue that may continue to cause abnormal bleeding or lead to other complications. Furthermore, the complexities involved in navigating an abnormally shaped uterus can increase the risk for procedural issues, including perforation or damage to surrounding structures.

Understanding the significance of uterine shape helps guide clinicians in determining patient suitability for this procedure, ensuring patient safety and the best possible outcomes.
