Abstract

The objective of this study is to investigate the influences of percutaneous nephrolithotomy (PNL) and open surgery nephrolithotomy on the systemic stress response, SIRS and renal function. Forty patients with kidney calculi were enrolled in the study. Twenty cases were randomized to the PNL group and the other twenty cases to the open surgery group. Levels of C-reactive protein (CRP), interleukin-6(IL-6), β(2)-microglobulin (β(2)-MG), respiration rate, heart rate, body temperature and white blood cell counts were examined. CRP and IL-6 were measured in all patients pre-operatively and on post-operative days 1, 3 and 6, respectively. There was significant difference in their pre- and post-operation levels (P < 0.05), with the peak of CRP and IL-6 observed at post-operative days 3 and 1, respectively. There was significant difference in both CRP and IL-6 between the two groups (P < 0.05). At post-operative day 1, there were 5 cases of SIRS in PNL group and 12 cases in open surgery group; there was significant difference between the two groups (P < 0.05). Serum β(2)-MG levels were measured as the same time as CRP and no significant changes were observed within or between the groups (P > 0.05). Urine β(2)-MG levels were also measured. There was significant difference between pre- and the first day post-PNL (P < 0.05); there was no significant difference between pre- and the third and sixth day post-PNL (P > 0.05). There was significant difference between pre- and first and third day post-open surgery (P < 0.05); but there was no significant difference between pre- and the sixth day post-open surgery (P > 0.05). There was significant difference between two groups at the first, third and sixth days (P < 0.05).

CONCLUSIONS:

The systemic stress response is activated both in PNL group and open surgery group to some extent. The degree of stress response of PNL is lower than that of open surgery, proving the advantages of PNL with reference to serum immunology. There were cases in both the groups with SIRS, but the degree of SIRS in PNL group was lesser than the other group. Both the groups have no obvious effect on glomerular filtration function after operation and have effect on renal tubular reabsorption in the early stage after operation; but the recovery of the PNL group is faster than the open surgery group. It is thus shown that PNL is much safer and more feasible and has lesser effect on renal function.
