Abstract Renal cancer represents 3-4% of all malignancies. Its incidental detection is becoming more frequent. Surgery is the gold standard treatment for T1 renal cancer. Still, surgery is not suitable for every patient due to comorbidities or previous kidney surgery. Guidelines provided by The American Urological Association recommend thermoablation therapies as an alternative to surgery in tumors under 3 cm. Experience regarding percutaneous cryoablation in renal tumors is scarce in Latin America and there are only a handful of publications in this region regarding this subject. The objective of this study was to assess the effectiveness and security of percutaneous cryoablation in a cohort of adult patients with cT1 renal cancer (smaller than 5 cm) as an alternative to surgery. The procedures were performed with CT or Cone Beam CT guidance and under general anesthesia in sterile conditions. Cryoablation was carried out on an outpatient basis. Follow up was done with imaging studies, blood test and clinical consultation. All patients had complete response in imaging studies. There were no complications in 61% of all of them, the remaining patients suffered grade-1 complications such as hematuria, urinary reten tion and perirenal hematoma. In conclusion, percutaneous cryoablation for renal tumors is a safe and effective alternative to surgery.

Resumen El cáncer renal representa el 3 al 4% de todas las lesiones malignas y su detección incidental es cada vez más frecuente. Para los tumores renales cT1a la cirugía es el tratamiento de elección. No todos los pacientes son candidatos a este tipo de tratamiento por elevado riesgo quirúrgico debido a comorbi lidades asociadas o antecedentes de cirugía en dicho órgano. Las guías de la Asociación Americana de Urología recomiendan la termoablación como alternativa a la cirugía en tumores menores a 3 cm. La experiencia con crioablación percutánea en tumores renales es escasa en Latinoamérica y hay pocas publicaciones al respecto en esta región. El objetivo de este trabajo fue describir la efectividad y seguridad de la crioablación percutánea en una cohorte de pacientes adultos con cáncer renal cT1 (menores a 5 cm) como alternativa al tratamiento quirúrgico. Los procedimientos fueron realizados con guía de tomografía computarizada o con un angiógrafo, en condiciones estériles y bajo anestesia general. Los pacientes fueron tratados en condiciones ambulatorias. El seguimiento se realizó con estudios por imágenes, análisis de laboratorio y consulta clínica. Todos tuvieron una respuesta completa constatada por imágenes en los controles evolutivos. El 61% no tuvo complicaciones y en el resto se observaron complicaciones grado 1 como hematuria, retención urinaria y hematoma perirrenal. Se concluyó que la crioablación percutánea es segura y efectiva como alternativa a la cirugía en pacientes con tumores renales.

Abstract: En | Text: En | PDF: En

Background: The incidence of renal cell carcinoma (RCC) is increasing globally due to an aging population and widespread use of imaging studies. Objective: The aim of this study was to describe the characteristics and perioperative outcomes of RCC surgery in very elderly patients (VEP), ≥ 75 years of age. Methods: This is a retrospective comparative study of 3656 patients who underwent the treatment for RCC from 1990 to 2015 in 28 centers from eight Latin American countries. We compared baseline characteristics as well as clinical and perioperative outcomes according to age groups (<75 vs. ≥75 years). Surgical complications were classified with the Clavien-Dindo score. We performed logistic regression analysis to identify factors associated with perioperative complications. Results: There were 410 VEP patients (11.2%). On bivariate analysis, VEP had a lower body mass index (p < 0.01) and higher ASA score (ASA >2 in 26.3% vs. 12.4%, p < 0.01). There was no difference in performance status and clinical stage between the study groups. There were no differences in surgical margins, estimated blood loss (EBL), complication, and mortality rates (1.3% vs. 0.4%, p = 0.17). On multivariate regression analysis, age ≥75 years (odds ratio [OR] 2.33, p < 0.01), EBL ≥ 500 cc (OR 3.34, p < 0.01), and > pT2 stage (OR 1.63, p = 0.04) were independently associated with perioperative complications. Conclusions: Surgical resection of RCC was safe and successful in VEP. Age ≥75 years was independently associated with 30-day perioperative complications. However, the vast majority were low-grade complications. Age alone should not guide decision-making in these patients, and treatment must be tailored according to performance status and severity of comorbidities. (REV INVEST CLIN. 2020;72(5):308-15)

ABSTRACT Objectives: The clinical significance of positive surgical margin (PSM) after a Nephron Sparing Surgery (NSS) is controversial. The aim of this study is to evaluate the association between PSM and the risk of disease recurrence in patients with pT1 kidney tumors who underwent NSS. Materials and Methods: Retrospective cohort study. A total of 314 patients submitted to a NSS due to stage pT1 renal tumor between January 2010 and June 2015 were included. Recurrence-free survival was estimated. The Cox model was used to adjust the tumor size, histological grade, pathological stage, age, surgical margins and type of approach. Results: Overall PSM was 6.3% (n=22). Recurrence was evidenced in 9.1% (n=2) of patients with PSM and 3.5% (n=10) for the group of negative surgical margin (NSM). The estimated local recurrence-free survival rate at 3 years was 96.4% (95% CI 91.9 to 100) for the NSM group and 87.8% (95% CI 71.9 to 100) for PSM group (p=0.02) with no difference in metastasis-free survival. The PSM and pathological high grade (Fuhrman grade III or IV) were independent predictors of local recurrence in the multivariate analysis (HR 12.9, 95%CI 1.8-94, p=0.011 / HR 38.3, 95%CI 3.1-467, p=0.004 respectively). Fuhrman grade proved to be predictor of distant recurrence (HR 8.1, 95%CI 1.6-39.7, p=0.011). Conclusions: The PSM in pT1 renal tumors showed to have higher risk of local recurrence and thus, worse oncological prognosis.

Objetive: to compare the results of posterior retroperitoneoscopic (PRA) or lateral transperitoneal approach (LTA) in laparoscopic adrenalectomy in the short and medium term. Material y methods: prospective cohort study. We included 22 patients who underwent 24 adrenalectomies (12 PRA and 12 LTA) between January 2015 and May 2016. In the PRA group, two simultaneous bilateral laparoscopic adrenalectomies were performed (1 synchronous bilateral adrenalectomy). Baseline, clinical and surgical outcome were compared. Results: the median follow-up time was 6.5 months (range: 1-16). The PRA and LTA groups were comparable in age, gender, BMI and presence of previous surgeries. Adenomas were the predominant lesions (41.7% in each group). The average operating time in PRA and LTA was 104.3 ± 21.2 and 146 ± 32.9 minutes, respectively (p=0.05). We found no differences in length of hospital stay, bleeding and complications. All patients achieved clinical cure. Conclusions: the PRA technique is a safe approach, with results comparable to LTA and shorter operating time. It also allows to intervene simultaneously and synchronously both adrenal glands without the need of repositioning the patient.

Objetivo: comparar los resultados obtenidos en adrenalectomía retroperitoneoscópica posterior (ARP) con los obtenidos por vía transperitoneal lateral (ATL) a corto y mediano plazo. Material y métodos: estudio de cohortes prospectivo. Se incluyeron 22 pacientes a quienes se les realizaron 24 adrenalectomías (12 ARP y 12 ATL) entre los meses de enero de 2015 y mayo de 2016. En el grupo ARP se realizó a 1 paciente adrenalectomía bilateral simultánea y a 1 paciente, bilateral sincrónica. Fueron comparados datos basales, clínicos, quirúrgicos y evolutivos. Resultados: la mediana de tiempo de seguimiento fue de 6,5 meses (r 1-16). Los grupos ARP y ATL fueron comparables en edad, sexo, BMI y presencia de cirugías previas. Los adenomas fueron las lesiones predominantes (41,7% en cada grupo). El promedio de tiempo operatorio en ART y ATL fue 104,3 ± 21,2 y 146 ± 32,9 minutos, respectivamente (p 0,05). No hallamos diferencias en tiempo de internación, sangrado y complicaciones. Todos los pacientes lograron curación clínica. Conclusiones: la técnica ARP es una vía segura, con resultados comparables a ATL y menor tiempo operatorio. También permite intervenir de manera simultánea y sincrónica ambas glándulas adrenales sin necesidad de reposicionar al paciente.

ABSTRACT Objectives: To evaluate functional and oncologic outcomes of partial nephrectomy (PN) in patients with a solitary kidney. Materials and Methods: A retrospective analysis of patients with a solitary kidney undergoing nephron-sparing surgery between March 2003 and March 2013 was performed. GFR was recorded before the procedure and 3 months after surgery, thus establishing a change (cGFR). Several variables that may influence cGFR were analyzed. Complications are herein described, namely bleeding, fistula, acute renal failure and end-stage renal disease (ESRD). Local recurrence and margin status are also described. Survival rates were calculated using the Kaplan Meier method (2 patients with metastasis at the time of surgery were excluded from the analysis). Results: Forty-five patients were available for analysis. Median follow-up was 27.56 months (r 3-96). Mean cGFR was-7.12mL/min (SD 2.1). Variables significantly related with lower GFR after surgery were loss of renal mass (p=0.01)) and male gender (p=0.03). Four patients (8.8%) experienced hemorrhage. Nine patients (20%) developed a urinary fistula. Only one patient with bleeding required open surgery. Two patients (4.4%) needed transient dialysis. Three patients (6.6%) developed ESRD. Four patients (8.8%) had positive surgical margins (PSMs) and four patients (88%) had local recurrence (2 of these had PSMs). Five patients (11.1%) died during follow-up. Four patients (8.8%) died because of renal cancer. Estimated 2-year overall survival, disease-free survival and cancer specific survival rates were 88.4% (CI 95% 70.5-96); 87.7% (CI 95% 68.1-96) and 92.4% (CI 95% 75-98), respectively. Conclusion: Loss of renal mass and male gender were associated with lower postoperative GFR. Our outcomes were comparable with those in the World literature.

The aim of this paper is to describe the epidemiological characteristics, clinical management and pathologic patterns in a population with renal tumors in our institution. Prospective data collection was performed over a period of 4.5 years, from January 2010 to June 2014. A total of 819 cases (796 patients) were treated for renal mass during this period. The mean age was 60.7 years (SD 13.1). There were 553 (69.5%) males (male to female ratio: 2.2: 1). Twenty nine per cent (230 patients) were obese (BMI ≥ 30). The diagnosis was incidental in 653 cases (79.7%), 48.8% presented one or more risk factors, being smoking the most frequent (34%). In 238 patients (29.9%) there was more than one comorbidity; 18% had preoperative creatinine ≥ 1.3 mg/dl. Lesions were ≤ 4 cm (cT1a) in 45% of the patients, and 10.8% (86) had metastases at diagnosis. The lesions were resected in 93.5% and actively monitored in 6.5% (not resected). In surgery treated patients, radical nephrectomy was performed in 51.5% of cases, and nephron sparing surgery in 48.5% of them. The laparoscopic approach was used in 56.2%. The pattern of presentation of renal masses is characterized by incidental diagnosis in early disease stages. Nephron sparing surgery is the first choice in nearly half of patients. Active surveillance has been used in a greater percentage than previously reported.

El objetivo del trabajo es describir las características epidemiológicas de la población con tumores renales en nuestra institución, la estrategia de diagnóstico y tratamiento y los hallazgos anatomo-patológicos. Se realizó una recolección prospectiva de datos epidemiológicos, de diagnóstico y tratamiento, así como también de los resultados patológicos en un período de 4.5 años, desde enero de 2010 a junio de 2014. En ese lapso 819 casos (796 pacientes) fueron tratados por masa renal. La edad media: 60.7 años (DE 13.1), 553 (69.5%) fueron hombres. El 29% (230) presentó obesidad (IMC ≥ 30). El diagnóstico fue incidental en 653 casos (79.7%). Un 48.8% (388 pacientes) presentó uno o más factores de riesgo, siendo el tabaquismo el más frecuente (34%). En 238 pacientes (29.9%) se presentó más de una comorbilidad. El 18% presentó creatinina preoperatoria ≥ a 1.3 mg/dl. El 45% de las lesiones fueron ≤ a 4 cm (cT1a). El 10.8% (86) de los pacientes presentaron metástasis al diagnóstico. El 93.5% de las lesiones fueron resecadas y el 6.5% fueron vigiladas activamente (no resecadas). Se utilizó la nefrectomía radical en el 51.5% y cirugía renal conservadora en el 48.5% de los pacientes operados. El abordaje laparoscópico fue utilizado en el 56.2%. El tumor renal se caracteriza en la actualidad por un diagnóstico incidental en estadios patológicos iniciales. La cirugía renal conservadora es la primera opción en casi la mitad de los pacientes. La vigilancia activa ha sido utilizada en un porcentaje mayor a lo comunicado en la literatura.

ObjetivosEstimar la prevalencia de los factores de riesgo cardiovascular y de enfermedades crónicas en población caficultora colombiana. MétodosEstudio transversal, entre febrero y noviembre de 2007. Muestreo multietápico y por conglomerados, 55 veredas de 13 municipios, 2 516 encuestas. Cuestionarios recomendados por OPS, mediciones antropométricas y bioquímicas. Análisis descriptivos univariados y bivariados, IC95%, pruebas de significan-cia, comparación con estudios previos. ResultadosLa prevalencia de fumadores actuales fue 21,1 % (IC95%: 19,2-23,3), sedentarismo 31,2 % (IC95%: 27,8-32,6), personas que consumen al día menos de 5 porciones entre frutas y verduras 86,3 % (IC95%: 84,4-87,9), consumo eleva-do de alcohol 2,2 % (IC95%: 1,6-3,2), hipertensión arterial 26,2 % (IC95%: 23,9-28,6), diabetes 4,6 % (IC95%: 3,6-5,8), hiperlipidemia 62,1 % (IC95%: 59,5-64,7), sobrepeso y obesidad 42,9 % (IC95%: 40,4-45,5). El 85 % tenían al menos 2 o más factores de riesgo simultáneamente. Sedentarismo, diabetes, hiperlipidemia y sobrepeso/obesidad fue mayor en mujeres (p<0,001). Consumo de alcohol y taba-quismo fue mayor en hombres (p<0,001). Edad, estado civil, educación, ingresos y sistema de salud estuvieron relacionados con los factores de riesgo estudiados. ConclusionesSe aportan nuevos conocimientos a la escasa información disponi-ble en poblaciones rurales latinoamericanas. En comparación con el segundo es-tudio nacional de factores de riesgo de enfermedades crónicas (ENFREC II) no se encontraron avances importantes en disminución de la prevalencia de factores de riesgo. Se requieren estudios adicionales para profundizar en los determinantes sociales y de los sistemas de salud, que expliquen los hallazgos de este estudio.

ObjectivesEstimating the prevalence of cardiovascular and chronic disease risk factors in a Colombian coffee-growing population. MethodsThis cross-sectional study was carried out from February to November 2007. Multistage conglomerate sampling of 55 rural areas in 13 municipalities led to 516 people being surveyed. The questionnaires used were recommended by PAHO (anthropometric and biochemical measurements). The resulting data was subjected to univariate and bivariate descriptive analysis using 95 % CI, significan-ce tests and comparison with previous studies. ResultsThere was 21.1 % (19.2-23.3 95 %CI) current smoker prevalence, 31.2 % sedentarism (27.8-32.6 95 % CI), 86.3 % people consumed less than 5 portions of fruit and vegetables per day (84.4-87.9 95 % CI), 2.2 % had high alcohol con-sumption level (1.6-3.2 95 %CI), 26.2 % suffered from hypertension (23.9-28.6 95 % CI), 4.6 % diabetes (3.6-5.8 95 % CI), 62.1 % hyperlipidaemia (59.5-64.7 95 % CI) and 42.9 % (40.4-45.5 95 % CI) were overweight or obese. 85 % had at least 2 or more risk factors simultaneously. Sedentarism, diabetes, hyperlipidaemia and being overweight /obese was greater in females (p<0.001). Alcohol consumption and smoking were greater in males (p<0.001). Age, civil state, education, income and health system were related to the risk factors being studied. ConclusionsThe study provided fresh knowledge concerning the lack of available information regarding rural Latin-American populations. Compared to the second Colombian study of chronic disease risk factors (ENFREC II), no important ad-vances were found regarding a reduction of the prevalence of risk factors. Further studies are required for going deeper into social determinants and health systems explaining this study's findings.

Objectives: To evaluate the ability of non contrast computed tomography (NCCT) to predict stone composition and fragility for treatment with extracorporeal shock wave lithotripsy (ESWL). Methods: 27 stones of about 10 mm from patients who had undergone different endourological procedures were collected. All patients had been evaluated with NCCT. To perform in vitro ESWL an experimental device was designed. Three thousand pulses were applied with 17.2 Kv intensity using an electromagnetic generator (Lithostar) to all stones. Composition of each fragment was studied with crystallographic study. Results were statistically analyzed with Student Test, Chi2 Test and multivariate study. Results: In vitro ESWL had a success rate of 59.26%. Average stone HU, grouped by composition: cistine 1015 HU, Calcium monohydrate oxalate 1193 HU, uric acid 419 HU, dihydrate calcium oxalate 2122 HU, struvite 1543 HU and basic phosphate magnesium 1517 HU. A statistically significant relationship was found between values which were lower than 500 HU and uric acid composition (p=0.0006), as well as values higher than 2000 HU and composition of dihydrated calcium acid (p=0.0244). In the group of stones with less than 1000 HU (n=11) efficacy was 81.1%, whereas it was 43.75% in the others (p=0.0479). We found a statistically significant relationship between uric acid and effectiveness (p=0.021). There was not statistically significant relationship between size and treatment effectiveness. Conclusions: The use of NCCT will allow predicting stone composition and fragility.

Objetivo: Desde la aparición de la litotricia extracorpórea por ondas de choque (LEOC), esta se ha convertido en el tratamiento de elección para los cálculos renales menores de 2 cm. La tasa de éxito de la misma varía entre el 60 al 99 % dependiendo de factores tales como la composición, tamaño, tipo de generador, localización, entre otros. El objetivo de este trabajo es evaluar si la densidad del cálculo en unidades Hounsfield (UH) mediante una tomografía computada sin contraste (TCSC) es capaz de predecir composición y fragilidad de la litiasis al tratamiento con LEOC. Métodos: Prospectivamente fueron recolectados 27 litos de alrededor de 10 mm provenientes de pacientes sometidos a diferentes procedimientos endourológicos (19 litotricias percutaneas, 2 litotricias ureterales y 6 litotricias vesicales), los cuales habían sido evaluados tomográficamente, midiéndose en UH la densidad de sus cálculos. Los litos fueron sometidos a litotricia extracorporea por ondas de choque "in vitro", para lo cual se conformó un dispositivo experimental. Se aplicaron 3000 pulsos a una intensidad de 17.2 Kw utilizando un generador electromagnético (Lithostar) a todos los cálculos. Se evaluó la composición de cada uno de los fragmentos mediante un estudio cristalográfico. Los resultados obtenidos fueron analizados estadísticamente utilizando el test de Student, test de Chi² y análisis multivariado. Resultados: La LEOC "in vitro" fue efectiva en 16 casos (59.26 %). Del total de los cálculos estudiados, 11 fueron puros y 16 tuvieron una composición mixta. Las UH promedio de los cálculos, agrupados por composición fue: cistina 1015 UH, oxalato de calcio monohidratados 1193, ácido úrico 419 UH, oxalato de calcio dihidratado 2122 UH , estruvita 1543 UH y fosfato básico de magnesio 1517 UH. Se encontró una relación estadísticamente significativa entre valores menores de 500 UH y composición de ácido úrico (p=0.0006), así como también valores mayores a 2000 UH y composición de oxalato de calcio dihidratado (p=0.0244). En el grupo de cálculos con menos de 1000 UH (n=11) la efectividad fue del 81.8 %, mientras que en el resto fue del 43.75 % (p=0.0479). Al asociar composición del cálculo con efectividad, encontramos una relación estadísticamente significativa entre presencia de ácido úrico y efectividad (p=0.021). No se encontraron relaciones estadísticamente significativas entre tamaño y efectividad del tratamiento. Conclusiones: El uso de la TCSC permitiría predecir la composición de oxalato de calcio dihidratado y ácido úrico. Valores de UH menores a 1000, aumentan significativamente el éxito del tratamiento.
