dc.description.abstractIntroduction The aim of this article was to quantify the effect of the use of holmium laser during intracorporeal lithotripsy in an ex vivo model.
dc.description.abstractMaterial and methods A simulated model for laser nephro-lithotripsy was designed. Two ex vivo porcine kidneys were used. Electronic thermometer electrodes were inserted on the upper calyx. Intracorporeal lithotripsy was simulated with a holmium laser. Intrarenal temperature was recorded both at the beginning and after one minute of laser use with delta temperature (DT) defined as the difference between them. Measurements were made at different irrigation heights (30, 40, and 50 cm H2O), frequency (Hz), and laser energy (J) in addition to the presence or absence of the access sheath. Analysis of factors associated with temperature change was performed.
dc.description.abstractResults Thirty-eight observations were recorded. The measurement without the use of access sheath showed an average DT of 4.9, 5.1, and 6.5 degrees C for 5, 10, and 15 Hz, respectively; however, with a sheath, DTs were 0.2, 0.5, and 1.5 degrees C. In terms of energy, mean DTs of 4.3, 6.1, 5.2, and 13.9 degrees C for 0.5, 0.8, 1.0, and 1.5 J were recorded; in contrast, with a sheath, averages of 0.4, 0.5, 0.5, and 3.8 degrees C, respectively were noted. In the adjusted model, energy, frequency, and use of sheath and water height were significant.
dc.description.abstractConclusions The configuration of the laser significantly modifies the intrarenal temperature and height of the bladder irrigation. The use of an access sheath provides lower intrarenal temperatures regardless of laser configuration and water height.
