PERKUTAN NEFROLİTOTOMİ YAPILAN HASTALARDA FARKLI ANESTEZİ YÖNTEMLERİNİN KARŞILAŞTIRILMASI

Abstract

Aim: Nowadays, percutaneous nephrolithotripsy (PNL) is the first choice of minimally invasive treatment for large and complex kidney stones. In this retrospective study, we compared the efficacy and safety of PNL surgeries performed under spinal and general anesthesia. Method: A total of 82 patients who underwent PNL 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 parameters and postoperative findings were recorded. Independent Samples t Test, Mann Whitney U and Chi-Square tests were used. P <0.05 was considered as statistical significance. Results: There was no statistically significant 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 stone-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 hospital 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: Spinal anesthesia is a fast and reliable method of anesthesia in patients scheduled for PCNL. It is thought that spinal anesthesia will be used with increasing frequency as it has advantages of short operation and fluoroscopy times.
