ABSTRACT

Background: Percutaneous Nephrolithotomy (PNL) is a well-established technique for the removal of renal stones. Large and complex renal stones are difficult stones to deal with. Aim of Study: This study is to evaluate our results of PNL for the treatment of large and complex renal stones concerningstone-free rates (SFR) and complications. Patients and Methods: From From 2012 to 2022, four hundred and four renal units with large and/or complex renal stones were subjected to PNL. Eighty-nine per cent were males and 11% were females. The average stone surface area (SA) was 872mm². Results: Stone-free rate (SFR) was 79% for cases submitted to PNL alone and 88.4% for those managed with auxiliary procedures. Hospital stay ranged from 2 to 21 days (Av. 3.6 days). The overall complication rate was 8% and was managed conservatively. Conclusion: PCNL is a safe and effective procedure for the management of large and complex renal stones. There was a significant decrease in the overall stone-free rate and increased complication rates with increased stone surface area. Stones >1500mm² are difficult stones for any modality. A multimodal approach should be thought of for large and complex renal stones.
