Seguridad y eficacia de la cirugía retrógrada intrarrenal en pacientes de diferentes grupos de edad / Safety and efficacy of retrograde intrarenal surgery in patients of different age groups

Objetivos: Evaluar la eficacia y seguridad de la cirugía intrarrenal retrógrada (CIRR) para tratar los cálculos renales en pacientes de diferentes grupos de edad. Pacientes y métodos: Se realizó un análisis retrospectivo de 947 pacientes que se sometieron a CIRR para cálculos renales entre enero de 2008 y enero de 2014. La edad en la CIRR se analizó tanto como una variable continua como categórica, y los pacientes fueron clasificados en 3 grupos de edad; ≤ 15 años en la cirugía (grupo i, n = 51), 16-60 años (grupo ii, n = 726) y> 60 años (grupo iii, n = 170). Se compararon los 3 grupos con respecto a las características del cálculo, los parámetros operativos y los resultados postoperatorios. Resultados; La tasa de ausencia de cálculos fue del 78,4% en el grupo i, 77,5% en el grupo ii, y 81,1% en el grupo iii (p = 0,587). Un análisis de regresión logística multivariante mostró que solo el tamaño del cálculo y el número de cálculos tuvieron una influencia significativa en las tasas de ausencia de cálculos después de CIRR. Se produjo un 13,7% de complicaciones intraoperatorias en el grupo i, 5,6% en el grupo ii, y 7,6% en el grupo iii. Las tasas de complicación global en niños eran más altas que en pacientes adultos, pero las diferencias no fueron estadísticamente significativas. Se descubrió que solo el tiempo de operación esataba asociado con el aumento del riesgo de complicaciones intraoperatorias. Las complicaciones médicas perioperatorias se desarrollaron en 8 pacientes (0,8%) en el grupo ii y 2 pacientes (1,1%) en el grupo iii. Un hombre de 48 años de edad murió a causa de shock séptico 5 días después de la cirugía. Conclusiones; Se observó que la CIRR era un procedimiento seguro y eficaz en todos los grupos de edad de pacientes con cálculos, por lo tanto, la edad no debe ser considerada como un factor limitante

Objectives: To assess the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in different age groups of patients. Patients and methods: We performed a retrospective analysis of 947 patients who underwent RIRS for renal calculi between January 2008 and January 2014. Age at RIRS was analysed both as a continuous and categorical variable and patients were categorized into three age groups; aged ≤ 15 years at surgery (group i, n = 51), 16 - 60 years (group Ii, n = 726) and > 60 years (group iii, n = 170). We compared the 3 groups with the regard to stone characteristics, operative parameters and postoperative outcomes. Results: The stone-free rate was 78.4% in group i, 77.5% in group ii, and 81.1% in group iii (P = .587). A multivariate logistic regression analysis showed that only stone size and stone number had significant influence on the stone-free rates after RIRS. Intraoperative complications occurred 13.7% in group i, 5.6% group ii, and 7.6% in group iii. Overall complication rates in children were higher than adult patients but the differences were not statistically significant. We found that only operation time was associated with the increased risk of intraoperative complications. Peroperative medical complications developed in 8 patients (.8%) in group ii and 2 patients (1.1%) in group iii. A 48-year-old man died from septic shock 5 days after the surgery. Conclusions: RIRS was observed to be a safe and effective procedure in all age groups of patients with stone disease, therefore age should not be considered as a limiting factor
