Summary
The study team aims to prospectively compare Placebo (local administration), ultrasound-guided transversus abdominis plane (UTAP) blocks, and laparoscopic-guided transversus abdominis plane (LTAP) blocks in patients undergoing robotic surgery of the prostate and kidney. The study team expects to be able to equally efficiently administer the blocks using direct visualization and ultrasound guidance. The study team expects that a negative result would obviate the need for longer operative time by eliminating the need for the separate ultrasound guided block while a positive result would demonstrate the increased utility of preoperative ultrasound blocks in managing postoperative pain.
