Saline Displacement of Rectal Wall for Improved Margin During MRI-Guided Transurethral Ultrasound Ablation (TULSA).
MRI-guided transurethral ultrasound ablation (TULSA) is an effective treatment for prostate cancer, but proximity to the rectum presents a challenge for ablation margin. We report the first case using saline infusion to displace the rectal wall during TULSA, allowing for improved treatment margins while minimizing rectal risk. A 67-year-old male with a Gleason score 3 + 4 = 7 lesion underwent right hemiablation with saline infusion achieving 5.3 mm displacement. Post-procedure imaging showed no rectal injury, and follow-up revealed no complications or recurrence. This novel technique demonstrates the safety and feasibility of saline displacement to enhance ablation coverage, offering a promising solution for treating lesions near the rectum.
期刊介绍：
CardioVascular and Interventional Radiology (CVIR) is the official journal of the Cardiovascular and Interventional Radiological Society of Europe, and is also the official organ of a number of additional distinguished national and international interventional radiological societies. CVIR publishes double blinded peer-reviewed original research work including clinical and laboratory investigations, technical notes, case reports, works in progress, and letters to the editor, as well as review articles, pictorial essays, editorials, and special invited submissions in the field of vascular and interventional radiology. Beside the communication of the latest research results in this field, it is also the aim of CVIR to support continuous medical education. Articles that are accepted for publication are done so with the understanding that they, or their substantive contents, have not been and will not be submitted to any other publication.
