From: Effect of nephrostomy sheath size on renal pelvic pressure during endoscopic combined intrarenal surgery: artificial kidney model study

Fig. 1

Experimental setup. (a) Nephrostomy, UAS, and f-URS placed in the artificial kidney model. The nephrostomy sheath was connected to the Urovac evacuator™ so that it was 70°above the horizontal plane, representing puncture of the lower calyx in a prone position in a human body. The UAS was installed at a site that resembled the renal pelvic ureteral junction. An arterial tonometry line was attached to the head side of it. (b) Artificial kidney model details. For nephrostomy and UAS, a silicone connector is used for the connection to the Urovac evacuator™, making it possible to change the sheath size. (c) Schematic representation of all equipment used in the experiment. UROMAT E.A.S.I.™ pump was used for irrigation from the nephroscope to achieve a steady continuous irrigation pressure
