Comparative Study between Outcome of Percutaneous Nephrolithotomy and Extracorporeal Shock Wave Lithotripsy in Patients with Renal Insufficiency

Abstract

Background: The incidence of stone formation in patients with renal insufficiency 17.5%, complete clearance of stone in these patients need least invasive procedure with safety of kid-ney parenchyma and kidney function. Objectives:To analyze outcomes of percutaneous nephrolithotomy (PNL) and shock wave lithotripsy (SWL) and their effect on kidney function for patients with renal insufficiency. Materials and methods: 52 renal insufficiency patients with renal stones presented to our de-partment randomized into two groups group A (25 patients) underwent PNL and group B (27 patients) underwent SWL and all results recorded and analyzed with Statistical Package for Social Science® (SPSS) and Microsoft Excel 2010. Results: Stone free rate was about 84% of patients in group A (25 patients) and about 26.6% of patients in group B with first session, while it`s about 88.9% for all patients in group B (27 patients) with some degree of improvement of kidney function. Conclusion: This study shows that both PNL and SWL are safe on patients with renal insuffi-ciency with improvement of kidney function.
