Abstract
Objective: In this study, we aimed to determine the factors affecting success in percutaneous nephrolithotomy.
Material and Methods: The data of 260 patients who underwent percutaneous nephrolithotomy for renal stone between January 2015 and October 2018 were analyzed retrospectively. The patients were evaluated by computed tomography in terms of stone-free postoperative period. Patients were divided into two groups as those with and without stones in the postoperative period. Age, sex, stone side, complications, transfusion rates and nephrostomy tube stay times were recorded. Stone location, stone operation history, stone size, stone skin distance, body mass index, operation and scopy times were compared in both groups.
Results: We determined that male gender, stone size and location, duration of operation and scopy time were the factors affecting the success of percutaneous nephrolithotomy. When we analyzed age, stone side, history of stone operation, body mass index and stone skin distance, we did not find any statistically significant difference. Nephrostomy tube stay times, complication and transfusion rates were similar in both groups.
Conclusion: Factors affecting success in percutaneous nephrolithotomy can be listed as sex, stone size and stone localization. In addition, it should be kept in mind that stone-free rates may decrease in patients with long operation and scopy times.
