Single-site port robotic-assisted simple nephrectomy (LESS) Introduction: Minimally invasive surgery in urology is rapidly advancing and Laparo-endoscopic single-site surgery (LESS) is not the exception. Such laparoscopic procedures are technically challenging and require an experienced laparoscopic surgeon due to the lack of port placement triangulation and instrument clashing. The benefi t of the da Vinci surgical system has recently introduced to LESS. We present two cases of robotic LESS nephrectomy. Matherials and Methods: Two patients, a female of 23 years old, diagnosed with right renal atrophy secondary to chronic pyelonephritis and one male patient with diagnosis of left staghorn calculi and renal atrophy. Both underwent to a total nephrectomy assisted by the da Vinci S surgical system through a single port incision using the GelPoint® access system. Results: The fi rst surgery was performed without incidents or conversion. The second patient required the installation of an additional robotic port for triangulation. The dock time and the mean operative time was 18 and 110 min. The mean estimated blood loss was 100 cc and the hospital stay was 27 hours. There were no complications. Conclusions: LESS robotic surgery is feasible using current robotic systems. However, there are several limitations. The design of specifi c technology for the use of the robot through single incision can solve this problem.
Robotic-assisted laparoscopic retroperitoneal lymph node dissection in post chemotherapy residual mass in testis cancer Introduction: The laparoscopic retroperitoneal lymph node dissection (L-RPLND) has shown results at least comparable to open surgery in terms of perioperative complications and oncological results, but its application in the post chemotherapy scenario is still matter of study. The development of robotic surgery and its advantages over laparoscopic surgery, make this an attractive option for complex procedures. We report our initial experience with robotic-assisted retroperitoneal lymph node dissection (R-RPLND). Methods: We describe the cases of two patients who underwent R-RPLND due to a Post Chemotherapy residual mass of a non-seminomatous testicular cancer. Results: Two patients, 27 and 30 years old, presented with retroperitoneal residual mass after 4 and 6 cycles of Bleomicin, Etoposide and Cis-Platinum. The fi rst patient had a 4.3 cm left para-aortic mass and the other had a 6 cm mass behind the third portion of the duodenum. The mean surgical time was 255 minutes (210-300), with an estimated mean blood loss of 450 cc (100-800) and a mean hospital stay of 60 hours (72-48). The pathologic result was Teratoma in both cases. There was no perioperative morbidity. Conclusions: We believe that R-RPLND is a feasible and safe alternative in selected patients. However still needs more experience and longer follow up to asess its oncological outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
