Micropercutaneous Nephrolithotomy: First 66 Cases Experience

Abstract

Objective: To present the initial experience with micro-percutaneous nephrolithotomy (micro-PNL) in patients with kidney stones.Methods: Medical records of 66 patients with kidney stones who underwent micro-PNL between December 2012 and March 2015 were retrospectively reviewed. The demographic data; stone side, location and size; operation and fluoroscopy time; intraoperative and postoperative complications; preoperative and postoperative hemoglobin levels and hematocrit; and operation success of the patient were evaluated.Results: The mean age of the patients was 46.62±13.94 years, and their mean body mass index was 25.77±2.62 kg/m2. The mean stone size was 186.7±34.23 mm2. The mean operation and fluoroscopy times were 80.46±43.67 min and 10.78±7.14 min, respectively. The mean hemoglobin drop was 0.86 g/dL. Twenty-four intraoperative and 17 postoperative complications were observed. An overall success rate of 95% (including clinically insignificant residual fragments) was achieved.Conclusion: Micro-PNL is a feasible, safe, and effective minimally invasive treatment modality for patients with small kidney stones.
