Factores de riesgo preoperatorios en pacientes con pielonefritis xantogranulomatosa sometidos a nefrectomía

Abstract

Identificar factores de riesgo asociados a complicaciones mayores en pacientes con pielonefritis xantogranulomatosa sometidos a nefrectomía.Análisis retrospectivo de expedientes clínicos de pacientes con pielonefritis xantogranulomatosa sometidos a nefrectomía. Se analizaron el sexo, el índice de masa corporal, el índice de comorbilidad de Charlson, la clasificación del estado físico de la American Society of Anesthesiologists, la etapa de Malek, el conteo leucocitario y los valores de creatinina. Las complicaciones se estratificaron en menores y mayores según la clasificación de Clavien-Dindo. Se realizó análisis univariado y bivariado usando las pruebas exacta de Fisher y ji al cuadrado de Pearson, y se establecieron medidas de riesgo utilizando la odds ratio (OR).Se analizaron 72 pacientes con una edad media de 50 años, el 83% mujeres, el 58.3% con urocultivo positivo y el 66% con litiasis renal. El 32% tuvieron alguna complicación mayor y el 15% requirieron admisión a la unidad de cuidados intensivos. Los valores elevados de creatinina (OR: 3.8; intervalo de confianza del 95% [IC95%]: 1.1-13; p = 0.02) y la etapa Malek II-III (OR: 4.5; IC95%: 1.2-17.5; p = 0.02) se asociaron con complicaciones mayores.El estadio de Malek y los valores elevados de creatinina incrementan el riesgo de desarrollar complicaciones mayores en los pacientes con pielonefritis xantogranulomatosa sometidos a nefrectomía.To identify preoperative risk factors associated with major complications in patients with xanthogranulomatous pyelonephritis undergoing total nephrectomy.Retrospective analysis of patient’s charts with xanthogranulomatous pyelonephritis who underwent nephrectomy. Risk factors included for analysis were gender, body mass index, Charlson comorbidity index, American Society of Anesthesiologists physical status classification, Malek’s stage, leukocyte count and creatinine levels. Postoperative complications were stratified in minor and major according to Clavien-Dindo’s classification. Univariate and bivariate analysis using Fisher’s exact test, Pearson’s chi-squared and odds ratio (OR) was performed.72 patients were analyzed, 83% women, mean age of 50 years, 58.3% positive urine cultures and 66% kidney stones. Major complications were present in 32% of cases, and 15% were admitted to the intensive care unit. Elevated creatinine (OR: 3.8; 95% confidence interval [95%CI]: 1.1-13; p = 0.02) and Malek’s stage II to III (OR: 4.5; 95%CI: 1.2-17.5; p = 0.02) were associated with major complications.The Malek Stage and elevated creatinine increases the risk of major complications in patients undergoing nephrectomy due to xanthogranulomatous pyelonephritis.
