A high-fidelity trainer for progressive renal mass excision and kidney-preserving surgery, enabling stepwise practice of partial nephrectomy from simple to complex cases with realistic haemostasis and renorrhaphy.

It facilitates key procedural skills such as renal mass identification and excision, vascular control and haemostasis, renorrhaphy and closure, and progressive training across tumor complexity. This model accurately represents the renal anatomy including Kidney with Perinephric Fat, Ureter, Renal Hilum, Gerota’s Fascia, and Psoas Muscle Base, as well as four perfused Renal Tumors of varying size and location for staged difficulty.
