The Only Hands-on Percutaneous Nephrolithotripsy Training Model for Targeting Kidney Stones.


The PCNL Trainer by Encoris features removable skin and accurate anatomic landmarks. It’s the perfect instruction tool for percutaneous nephrolithotomy procedures. The PCNL Trainer can even be used to simulate hydronephrotic conditions.

PCNL is the minimally invasive procedure of choice for the treatment of renal calculi, especially when extracorporeal shockwave lithotripsy is not an option. The PCNL Trainer can be used to instruct surgeons in the removal of a variety of kidney stone types, including:

  • Calcium stones
  • Cystine stones
  • Uric acid stones
  • Staghorn stones
  • Struvite stones

PCNL How-To Instructional Sheet


A First-of-its-kind PCNL Kidney Trainer….delivering a realistic, hands-on surgical experience for practicing the removal of kidney stones.

Using reusable kidney cartridge inserts simulating different types of kidney stone conditions, surgeons and trainees can practice the removal of kidney stones whether they are large staghorn, upper and lower caliceal stones, or hydronephrotic (blocked ureter) stone conditions.


  • Surgeons and students can thoroughly practice PCNL procedures as a simulated operation using either ultrasound or fluoroscopy.
  • Features life-like skin and subcutaneous tissue layers as well as built-in anatomical markers such as the iliac crest of the hip, thoracic 11th and 12th ribs, and a thoracic spine.
  • Provides many different orientations of the kidney and multi-surgical stone conditions via interchangeable kidney cartridges.
  • Kidneys can be filled with water providing a hydronephrotic condition as well as fluid drip once a guide needle is placed.
  • Trainees can practice access to the kidney from multiple angles and entry points either from the back or through the ureter.
  • The trainer provides a clean operating environment and is reusable for multiple training sessions eliminating the need for cadavers or animals for training.

The PCNL Kidney Training System can be used with most any urological instrumentation and ureteroscopes for various procedures to include the removal of kidney stones using either fluoroscopy or ultrasound. The internal kidney anatomy is hollow, containing 8 calyces with several embedded stones of assorted sizes and locations.

The model acts much like human anatomy, mimicking renal access for common procedures in a urologic practice. The model can be used via ultrasonographic guidance, CT/MRI and robotic assisted percutaneous guidance and endoscopic guidance for drainage of an obstructed and hydronephrotic kidney and antegrade renal access prior to percutaneous renal surgeries such as percutaneous nephrolithotomy and percutaneous endopyelotomy.
