How I do it: Surgically inserted transversus abdominis plane (TAP) catheters for flank incisions. 
Pain control following major abdominal surgery remains a significant barrier to patient comfort.  Although thoracic epidurals have been used to provide analgesia for these surgeries, the transversus abdominis plane (TAP) block is gaining popularity.  The TAP catheter insertion method has transformed over the past two decades from a blinded technique to one conducted primarily under ultrasound guidance by anesthesiologists.  Recently, however, interest has increased on the potential for direct surgical insertion of catheters into the TAP plane following flank incisions due to anatomical considerations.  Proposed advantages include a reduction in operating time, requirement of minimal expertise and increased accuracy of catheter placement.  In this report, we describe the rationale and the technique of surgical insertion of TAP catheters following open nephrectomies as performed by urologists at our institution.
