Brief Summary

Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure considered as the treatment of choice for the management of large-scale and fully-formed kidney stones.This procedure has a 5% risk of complications including bleeding, the lesion of the collecting system, the risk of urinary infection and bacteremia. New surgical tools such as dilatation of the nephrostomy tract with mechanical dilatation contribute to the reduction of these risks, together with an improvement in the operative times and a lower rate of complications. At present there are multiple scales measuring the lithiasic morphology (Guy, the STONE nephrolitometry score system and the nomogram of the Office of Clinical Investigation of the Endourology Society - CROES) which allow to evaluate the degree of complexity of the stone, the possibility of residual stones and the risk of complications. These tools allow us to do a better analysis of the risk factors of the patient who will be taken to this type of endoscopic procedure in order to decrease morbidity and complication rates. Hypothesis: The use of pneumatic dilators during percutaneous nephrolithotomy reduces the rates of intraoperative and postoperative complications, which would have an impact on hospitalization times and surgical success for the management of renal stone.
