Journal of Clinical and Experimental Investigations

Abstract

Aim: The aim of this study was to evaluate the results of percutaneous stone surgery that performe in a regional state hospital.
Materials and methods: We retrospectively analyzed 183 percutaneous nephrolithotomy (PNL) performed cases that treated at our clinic between June 2010 and July 2011. After necessary laboratory and radiological investigations, we performed PNL for the patients those diagnosed as having stones needed surgery. After surgery, we investigated radiologically whether residual stone fragments remained or not. When there were residual stone fragments (bigger than 4 mm), we performed ESWL, repeated percutaneous interventions and surveillance protocols. In six patients, open surgery was needed during PNL.
Results: Of the totally 183 patients underwent PNL at our clinic, 102 were male and 81 were female. The mean age was 37.6 and mean stone burden was 35.5 mm². Stone-free rate was 75.4% and the rate of the patients who have residual stones (bigger than 4mm) was 25.7%. Stone free rates were 95% and 86% for stone burden lesser and more than 2 cm², respectively. The mean blood loss was 186ml for per operational case. Totally four patients (8.5%) underwent blood tranfusion.
Conclusion: As a result, because of its high stone-free rates, the shorter hospital stay, minimal surgical scar and absence of wound infection, PNL is preserving its place for the treatment of stones bigger than 2 cm².
