V7-10 ROBOTIC TRAPDOOR PARTIAL NEPHRECTOMY FOR COMPLETELY ENDOPHYTIC TUMORS

both cases, extensive adhesions were found around the kidney, making anatomical identification and dissection difficult. Intra-operative ultrasound and a doppler probe were used to facilitate identification of anatomical structures. The fourth robotic arm and robotic hook were used to help mobilize the kidney and expose important structures. RESULTS: The results of the two cases are presented in Table 1. Both cases were completed robotically with no intraoperative complications. Post-operative course was uneventful and both the patients were discharged on day three. CONCLUSIONS: Salvage robotic kidney surgery for complications of robotic partial nephrectomy is rare but challenging. Intraoperative ultrasound, intraoperative doppler, the fourth robotic arm, and robotic hook canall beuseful todefineanatomyand facilitatedissection indifficult cases.
