Decreased renal function is prevalent in patients with small unilateral renal tumors even with a normal contralateral kidney. Ablative or extirpative nephron sparing techniques are effective for preserving renal function in these patients.

While still under development with more refinements needed, completely transvaginal cholecystectomy using MAGS instruments is feasible. By offering triangulation and rigidity, MAGS may facilitate a NOTES approach while alleviating shortcomings of a flexible platform.

Single trocar laparoscopic nephrectomy using magnetically anchored instrumentation is technically feasible, demonstrating that intracorporeal instrument manipulation may overcome the limitations of current laparoscopic and robotic surgery by allowing unhindered intra-abdominal movement. This single access technique may be used with natural orifice surgery approaches and it has the potential to realize incision-free intra-abdominal surgery.

Renal cryodestruction via laparoscopic access achieves complete tissue ablation without complications. The double freeze cycle produced significantly larger areas of LN than the single freeze regardless of the thaw process. The type of thaw process did not affect the amount of tissue damage. Utilizing a double 15-minute freeze cycle with the faster active thaw process will effectively cryoablate renal tissue as well as significantly reduce overall operative time.
