Percutaneous Nephrolithotomy: Our Results of a Single-Centre Analysis in 2300 Cases

Aim: In this study, we evaluated the results of 2300 patients who underwent percutaneous nephrolithotomy (PNL) between March 2002 and April 2013. Methods: In our clinic, a total of 2300 PNL operations were performed between March 2002 - April 2013. Demographic characteristics (age, gender), body mass index, stone features (side, size, location), clinical characteristics of the urinary tract (renal anomaly, previous surgery, previous extracorporeal shock wave lithotripsy), operation parameters (duration of the intervention and fluoroscopy, number of access, location of access, transfusion, complications), post-operative data (length of hospital stay, transfusion, complications, stone-free) were recorded on PNL forms. The data were analyzed retrospectively. Results: Of all the PNL operations, 1225 (53.2%) were left-sided, 1074 (46.6%) were right-sided and 1 was bilateral. The mean age of the subjects was 43.5 (7-83) years and the mean body mass index was 26.6 kg/m2 (12-51). A total of 46 (2%) cases had renal anomalies. There were 16 patients with horseshoe kidney. More than one accesses was performed in 18.6% of the patient and intercostal access was done in 9.8%. Perioperative and post-operative transfusion rates were 1.4% and 2.9%, respectively. The mean stone size was 7.5±4.1 cm2. Stone-free (SF) rate was 65.1% and success rate was 78.5%. Conclusion: With increasing experience and advances in endourology, PNL is being widely performed with low morbidity and high success in our country as in the world.
