Design and validation of a low-cost, high-fidelity model for robotic pyeloplasty simulation training.

Introduction/background: Owing to restrictions in operative experiences, urology residents can no longer solely rely on 'hands-on' operative time to master their surgical skills by the end of residency. Simulation training could help residents master basic surgical skills and steps of a procedure to maximize time in the operative room. However, simulators can be expensive or tedious to set up, limiting the availability to residents and training programs.

Laparoscopic radiofrequency ablation of small renal tumors: long-term oncologic outcomes.

Introduction: Unlike percutaneous radiofrequency ablation (RFA) of small renal tumors, there are limited data assessing the long-term efficacy of laparoscopic RFA. Although the ablation cannot be visualized as reliably as with cryoablation, laparoscopic RFA allows for improved mobilization and placement of probes under direct vision. We reviewed our experience with laparoscopic RFA to assess long-term oncologic outcomes.
