Ureteral Obstruction & Hydronephrosis Simulator

Interactive 3D hydronephrosis simulator: set a ureteral obstruction's severity and elapsed duration, watch the kidney's collecting system distend as trapped urine backs up, and see how internal pressure and kidney tissue health respond over time.

Set how completely a kidney stone blocks the ureter and how long that blockage has been left in place, then watch the kidney's collecting system swell as trapped urine backs up behind it. Internal pressure and kidney tissue health respond live, so a brief severe blockage can be directly compared against a prolonged partial one to see which does more lasting damage.

⚙ Under the hood

Set a kidney-stone ureteral obstruction's severity and elapsed duration in this 3D model, and watch the kidney's collecting system distend as trapped urine backs up. Live readouts track rising internal pressure and progressively declining kidney tissue health, letting you compare a brief severe blockage against a prolonged partial one.
