RESUMO
INTRODUCTION AND OBJECTIVES: To analyze the evolution of kidney function after radical nephrectomy and to evaluate risk factors for adverse cardiovascular events during a long follow-up. MATERIAL AND METHODS: Retrospective study of patients submitted to radical nephrectomy due to renal cancer from January of 1996 to January of 2016. We evaluated their renal function after nephrectomy and during follow-up. We analyzed the possible predictive factors for adverse cardiovascular events with univariate and multivariate logistic regression analyses. RESULTS: There was an acute drop in glomerular filtration rate (GFR) after nephrectomy (21.2ml/min), which stabilized during follow-up in most cases. We evaluated the possible predictive factors for adverse cardiovascular events with logistic regression analyses, which presented previous cardiovascular disease (0,270, 95% CI 0,123-0,594, P<.001), diabetes (0,364, 95% CI 0,162-0,818 P=.015) and de novo hypertension (0,239, 95% CI 0,098-0,581, P=.002) as independently associated with the occurrence of adverse cardiovascular events. CONCLUSION: There was a deleterious effect in renal function after nephrectomy which remained stable during subsequent years in most patients. Approximately half of our patients had a GFR lower than 60mL/min after nephrectomy. Previous cardiovascular disease, diabetes and de novo hypertension were shown as risk factors for adverse cardiovascular events.

OBJECTIVES: Occasionally, the development of laparoscopic procedures allows the performance of combined surgeries. Currently, some of these can be carried out by trans-umbilical single-port laparoscopy. MATERIAL AND METHODS: We report a patient with renal tumor of 4.5cm and cholelithiasis who undergone to trans-umbilical single port-right radical nephrectomy with concomitant cholecystectomy. This is the first case reported in Spain that this combined procedure is performed using umbilical single port surgery. RESULTS: No complications (intra or postoperative) have been described in this case, achieving proper control of tumor pathology and an excellent cosmetic outcome. CONCLUSION: In those cases in which multidisciplinary approach is required, surgery can be performed by trans-umbilical single-port laparoscopy as consequence of its reduced postoperative morbidity and better cosmetic results.
