AUA 2011 - The development of patient specific simulator for laparoscopic renal surgery - Session Highlights

WASHINGTON, DC USA ( - The research group from Japan first presented their initial work on a patient specific laparoscopic nephrectomy simulator at the 2009 AUA Annual Meeting (J Urol 2009; 181(4) Supplement: Abstract 2176).

With additional development, this team now presents their successfully developed patient specific simulator for laparoscopic renal surgery.

Utilizing dynamic CT studies of the patient the data is entered into the computer platform of the simulator. The patient-specific anatomy of the organs, including renal vasculature is then reproduced for the individual patient and the surgeon can truly perform a preoperative rehearsal of that specific patient’s laparoscopic nephrectomy. The simulator reportedly simulates both the dissection of the renal vessels and the extirpation of the kidney. These researchers have also designed a haptic device which reproduces appropriate surgical instrument to tissue interactive resistance. They have also simulated active bleeding in the case of renal vessel injury which would make this a valuable learning platform for trainees in laparoscopic renal surgery. We now anxiously await the construct and predictive validity testing of this unique surgical simulator.
