Multi-institutional Evaluation of Producing and Testing a Novel 3D-Printed Laparoscopic Trainer.

Objective: To create, distribute, and evaluate the efficacy of a portable, cost-effective 3D-printed laparoscopic trainer for surgical skills development.

Methods: The UCI Trainer (UCiT) laparoscopic simulator was developed via computer-aided designs (CAD), which were used to 3D-print the UCiT. Once assembled, a tablet computer with a rear-facing camera was attached for video and optics.

Active surveillance for incidental renal mass in the octogenarian.

Objective: To evaluate the oncologic outcomes among a large cohort of octogenarian patients placed on active surveillance for a localized renal mass.

Methods: We retrospectively reviewed patients ≥80 years of age presenting for asymptomatic, incidentally detected clinically localized stage T1 renal mass between 2006 and 2013 who were followed by active surveillance (AS). The primary endpoint was development of metastatic renal cell carcinoma.
