RESUMO
OBJECTIVES: We present our experience in single-stage bilateral retrograde intrarenal surgery (RIRS), analyzing the stone free rate (SFR), surgical time, hospital stay, pre- and post procedure creatinine, stone composition and complications. METHODS: Between April 2012 and February 2016, 24 RIRS were carried out in 12 patients with bilateral renal stones. Patients were 9 men and 3 women with a median age of 47.5 (range:55),IMC: 23.59 (range: 12.5). RESULTS: Mean number of stones per renal unit was 2.7 (range: 12), mostly located in the renal pelvis (40%), with an average size of 16.08±8.06 mm and an average stone burden of 258.54±242.59 mm². The SFR at 3 months was 83.33%. Average operation time was 75 minutes and median hospital stay was 2 days. Three complications were recorded (25%), all of them minor (Clavien I-II). No major complications were recorded (Clavien III-V). CONCLUSIONS: Single-stage bilateral RIRS is a safe and effective tool for the treatment of patients with bilateral renal stones.

OBJETIVOS: Presentar nuestra experiencia en cirugía intrarrenal retrógrada (RIRS) bilateral en un mismo acto quirúrgico, analizando la tasa de pacientes libres de litiasis (SFR), el tiempo quirúrgico, la estancia hospitalaria, las complicaciones, las diferencias entre la creatinina pre- y postoperatoria y la composición de los cálculos. MÉTODOS: Entre abril de 2012 y febrero de 2016 se han realizado 24 RIRS en 12 pacientes con litiasis renal bilateral, entre los que se encuentran 9 hombres y 3 mujeres, con mediana de edad de 47,5 (rango: 55), IMC: 23.59 (rango: 12,5). RESULTADOS: El número de cálculos por unidad renal es de 2,7 (rango: 12), localizados preferentemente en la pelvis renal (40%), con un tamaño medio de 16,08±8,06 mm y una carga litiásica media de 258,54±242,59 mm2. El SFR a los 3 meses es de 83,33%. El tiempo operatorio medio ha sido 75 minutos y la estancia hospitalaria mediana de 2 días. Se han registrado 3 complicaciones (25%), todas ellas complicaciones menores (Clavien I-II). No se han registrado complicaciones mayores (Clavien III-V). CONCLUSIONES: La RIRS bilateral en un mismo acto quirúrgico es una herramienta eficaz y segura para el tratamiento de pacientes con litiasis renales bilaterales
