Percutaneous Nephrolithotomy for the Treatment of Renal Stones Larger than 2

Results: In a cohort of 88 patients (57 male and, 31 female) PCNL was performed for renal stone treatment. The mean age was 33.5 (9 – 65) years. The mean operative time was 85 (60 – 180) minutes and the mean stone size was 3.2 cm range (2.5-4.8) cm. There were 37 staghorn and 51 non staghorn stone. PCNL via a single access tract was accomplished in 86% (76/88) of procedures, with upper pole calyx in 30, middle calyx in 27 and lower pole calyx in 19 procedures, while multiple tracts were used in 14% of procedures (12/88) with 09 procedures using the upper and middle calyxes and 05 procedures using lower and middle calyxes. The stone-free rates for staghorn stone at discharge and at 3 months were 83.7% and 90.8% respectively, while for non staghorn stone the figures were 85.8% and 92.5% respectively. Postoperative complications were observed in 9% of the procedures (8/88), the commonest of which was bleeding necessitating blood transfusion in 4 patients.
