Cirugía percutánea de la litiasis renal en la era de la litotripsia extracorpórea: Experiencia en 301 pacientes

Abstract

Percutaneous renal surgery. Experience in 301 patients Introduction: Percutaneous renal surgery was introduced more than 20 years ago in urological practi- ce. Extracorporeal Shock Wave Lithotripsy (ESWL) enter the urological scene shortly after. Our objective is to show our experience in percutaneous renal surgery after the introduction of the ESWL in our institution. Material and Methods: Surgical outcomes of 301 patients who underwent percutaneous renal surgery as treatment of renal stones were analyzed. This series begins just before the introduction of ESWL in our unit. Results: Renal pelvis was the most frequent localization with 142 cases (47.2%). There were 51 patients with straghorn calculi. 255 (84.7%) were stone free after one single procedure. Residual fragments were managed with many methods, until only 16 patients (5.4%) had residual fragments. Complications occurred in 26 patients (8.9%). There was no mortality. Conclusions: Percutaneous surgery is an important tool in the management of renal stones. In general, renal stones managed with this procedure, are more complex, however the achievement of good results is possible.
