Evaluate the Severity of Complications for Percutaneous Nephrolithotomy and Open Surgery for Large Renal Stone

Abstract

Urinary stone disease is the third most common problem in urology clinics after urinary tract infections and prostate disease. Objectives: evaluate severity of complications of percutaneous nephrolithotomy (PNL) and open surgery for large renal stones. Patients: 150 adult patients with renal stones more than 2 cm were distributed into two equal groups. Group A had PNL and group B had open surgery. Design: Quasi-experimental research design. Setting Assiut Urology and Nephrology Hospital. Tools: (1) Patient assessment sheet and (2) Clavien-Dindo grading system for classification of surgical complications. Results: No significant relation between the both group regarding complications, stone clearance and need for blood transfusion, while mean hospital stays showed significant relation between the both group. As a group (A) stay only 3.7±1.2 days in hospital after operation while group B stay longer time, 6.1±0.53 days after operation.Conclusions: Open renal surgery for large sized stones still has its role in selected cases with stone clearance and complications rates comparable to PNL. Recommendation: The choice between PNL and open surgery for renal stones should be individualized for each patient.
