Résumé fourni par la source

Background: PCNL is standard surgical treatment for renal stone > 2.0 cm and stone resistant to Extracorporeal Shock Wave Lithotripsy. This study was conducted to evaluate the outcome of percutaneous nephrolithotomy in renal anomalies. Methods: This cross sectional study was conducted at The Kidney Center postgraduate training institute Karachi from January 2010 to June 2017, comprised of 60 patients of stone size (median, IQR) 2.75,1.2. Percutaneous nephrolithotomy was done under general anesthesia; intra operative flouroscopy was done for stone clearance. Post-operative x-ray KUB was done to verify the clearance of stone. Results: Out of the 60 patients, most patients had horseshoe kidney 35 (58.3%) with right sided renal stone and majority of the stones are located in pelvis 37 (61.7%). 48 (80.0%) patients required nephrostomy while only 24 (40%) required Double J Stent insertion. In 42 (70%) patients 100% clearance was achieved and only 20 (33.3%) patients needed secondary procedures. Double J Stent insertion was done in both types of renal abnormality. In case of 100% clearance Double J Stent was inserted in 3 (33.3%) patients with malrotation while 7 (46.7%) horseshoe kidneys required Double J Stent insertion. Conclusion: Percutaneous nephrolithotomy is a safe treatment option in renal anomalies patients with renal stones.
