Objective: Nowadays, percutaneous neph- rolithotripsy (PCNL) is the first choice of mini- mally invasive treatment for large and complex kidney stones. In this retrospective study, we compared the efficacy and safety of PCNL sur- geries performed under spinal and general anest- hesia.
Material and Methods: A total of 82 pati- ents who underwent PCNL between October 2016 and August 2018 were included in the study. There were 34 patients in the general anesthesia group (group 1) and 48 patients in the spinal anesthesia group (group 2). All patients’ stone and urinary system features, operation parame- ters and postoperative findings were recorded. Independent Samples t Test, Mann Whitney U and Chi-Square tests were used. P<0.05 was con- sidered as statistical significance.
Results: There was no statistically signifi- cant difference between the two groups in terms of mean age, gender and stone sizes respectively (p=0.20, p=0.83, p=0.24). The mean operative time was 57.91±10.18 minutes (min) in Group 1 and 53.56±9.33 min in group 2, and there was a statistically significant difference (p=0.04). The mean fluoroscopy time in Group 1 was 4.23±1.54 min and 3.56±1.25 min in group 2 and there was a significant difference (p =0.008). While the sto- ne-free rate was 84.2 % in group 1, this rate was 85.5 % in group 2 and no significant difference was found (p=0.31). The mean length of hospi- tal stay was 51,08±11,27 hours in group 1 and 50,12±11,18 hours in group 2 (p=0,70). There was no postoperative headache in group 1, but 4 patients had postoperative headache in group 2, but this was not statistically significant (p=0.13). Conclusion: PCNL can be performed qu- ickly and reliably under spinal anesthesia with high success and low complication rate as an al-ternative to general anesthesia in selected cases.
