In recent decades, regional plane blocks via ultrasonography have become very popular in regional anesthesia and are more commonly used in pain management. The transversus abdominis plane (TAP) block is a procedure where local anesthetics are applied to block the anterior divisions of the tenth thoracic intercostal through the first lumbar nerves (T10-L1) into the anatomic space formed amidst the internal oblique and transversus abdominis muscles located in the antero-lateral part of the abdomen wall. The most important advantage this block method is that ultrasonographic identification is easier and its complications are fewer compared with central neuroaxial or paravertebral blocks. Here, we describe three cases where pain management renal colic was treated with the TAP block. (C) 2020 Elsevier Inc. All rights reserved.
