Table 1.
Demographic data and the degree of hydronephrosis.
Table 2.
The changes in PI, MAP, and eGFR in the 3 hydronephrosis groups. (compared with repeat measurement ANOVA and then Turkey HSD test each other).
Table 3.
Relationships between baseline clinical parameters and the percent changes in MAP, PI, eGFR after stone disintegration.
Figure 1.
Interquartile range (IQR) of Perfusion Index (PI) in patients with Grade I, II, and III hydronephrosis.
The PI increased after induction of anesthesia, and increased further after stone disintegration.
Figure 2.
Interquartile range (IQR) of mean arterial pressure (MAP) in patients with Grade I, II, and III hydronephrosis.
The MAP decreased after induction of anesthesia, but there were no further changes during stone evacuation.
