Abstract
IntroductionTraining systems for laparoscopic surgery are useful for basic training but are not suitable for specific training corresponding to the condition of a given patient. We, therefore, have developed an unusual training system: a patient-specific simulator for laparoscopic surgery. When specific data of each individual patient are entered, this system helps surgeons perform a “rehearsal” operation. We applied this technique in laparoscopic surgery by using volume data obtained by multislice computed tomography imaging.Case presentationA 39-year-old Japanese woman consulted a doctor because of back pain and underwent pyeloplasty after an examination revealed a ureteropelvic junction obstruction. Computed tomography data showed that the network of arteries and veins was very complicated. Therefore, we decided to use our simulator before performing surgery. Simulation was helpful because we could obtain information about the complicated vessel network and “rehearse” the procedure.ConclusionsOur simulator allows surgeons to perform a sham operation with different perspectives and tactile sensations and has received favorable reviews from users.

Summary
Laparoscopic surgery has attracted attention as a minimally invasive type of surgery because of the small size of surgical wounds and early recovery [1]. Laparoscopic pyeloplasty has developed worldwide as the first minimally invasive option to match the success rates of open pyeloplasty [9,10] Success in this procedure requires a pre-operative examination of crossing vessels and the urinary tract. Simulation was helpful because the network of arteries and veins was very complicated in this case and we could “rehearse” the surgery. Case presentation A 39-year-old Japanese woman consulted a doctor because of back pain, and UPJO was detected after an examination She was referred to our department and agreed to undergo laparoscopic surgery. The locations of the arteries, veins, ureter, and UPJO were almost the same. The anonymous vein, which tightened the ureter and ran dorsal to it on the simulator, ran ventral to it during surgery (Table 1)
