Evaluation of surgical models for renal collecting system closure during laparoscopic partial nephrectomy

The porcine and canine models are inadequate for evaluating renal collecting system closure after partial nephrectomy. Our high-pressure partial occlusion model was similarly inadequate. The limitations of these animal models should be considered when reviewing published data regarding technologies for partial nephrectomy. Future data regarding novel technologies for partial nephrectomy should also be carefully considered before clinical application.
