RESUMEN
INTRODUCTION: Primary hyperparathyroidism (PHPT) is a common endocrine disorder characterised by hypercalcaemia and parathormone increase. Decreased glomerular filtration rate (<60ml/min) continues to be a parathyroidectomy (PTX) criterion in asymptomatic PHPT. The influence of PTX on renal function evolution is the subject of debate. OBJECTIVE: To analyse the clinical, laboratory and histological characteristics of patients undergoing PHPT, as well as renal function evolution after PTX. MATERIAL AND METHODS: Retrospective study of 297 patients diagnosed with PHPT and referred to surgery in a single centre between 1998 and 2016. Laboratory parameters were determined at baseline, one week and one year after PTX. RESULTS: The Incidence of PTX was 38 cases/million/year. Mean age was 60±14 years and 80.5% of the patients were female. Approximately 65.3% were asymptomatic. Nephrolithiasis was the most common clinical finding (33%), followed by bone involvement (29.5%). PTX indications were: clinical symptoms (34.7%), hypercalcaemia>11.2mg/dl (27%), nephrolithiasis (13%), low bone mass (12%), age<50 years (11%) and decreased glomerular filtration rate<60ml/min (2.3%). For diagnostic localisation, spect-MIBI had a sensitivity of 92% and cervical ultrasound of 70%. A total of 94.3% of PHPT cases were due to a parathyroid adenoma. After PTX, normalisation of PHPT-related parameters was observed. We found a significant increase in serum creatinine levels (0.81 vs 0.85mg/dl, P<.001) from the first week post-PTX until the end of the first year. The renal function was only found to be significant in patients with glomerular filtration rate>60ml/min (baseline serum creatinine levels 0.77mg/dl vs serum creatinine levels after one year 0.81mg/dl, P<.001). CONCLUSIONS: PHPT was asymptomatic in most patients who underwent surgery. Hypercalcaemia and nephrolithiasis were the most common indications of parathyroidectomy in asymptomatic patients. MIBI scan was the most useful localisation method. Surgical treatment of PHPT is followed by renal function impairment, which persists after the first week post-PTX.

BACKGROUND: A multidisciplinary approach and Doppler ultrasound (DU) assessment for the creation and maintenance of arteriovenous fistulas (AVF) for haemodialysis can improve prevalence and patency. The aim of this study was to analyse the impact of a new multidisciplinary vascular access (VA) clinic with routine DU. MATERIAL AND METHODS: We analysed the VA clinic results from 2014 and 2015, before and after the implementation of a multidisciplinary team protocol (vascular surgeon/nephrologist) with routine DU in preoperative mapping and prevalent AVF. RESULTS: We analysed 345 and 364 patients from 2014 and 2015 respectively. The number of surgical interventions was similar in both periods (p=.289), with a trend towards an increase in preventive surgical repair of AVF in 2015 (17 vs. 29, p=.098). 155 vs. 169 new AVF were performed in 2014 and 2015, with a significantly lower primary failure rate in 2015 (26.4 vs. 15.3%, p=.015), and a non-significant increase in radiocephalic AVF, 25.8 vs. 33.2% (n=40 vs. 56), p=.159. The concordance between the indication at the clinic and the surgery performed also increased (81.3 vs. 93.5%, p=.001). Throughout 2015 fewer complementary imaging test were requested from the clinic (78 vs. 35, p <.001), with a corresponding reduction in costs (87,716 vs. 59,445). CONCLUSIONS: Multidisciplinary approach with routine DU can improve VA results, with a decrease in primary failure rate, higher likelihood of radiocephalic AVF, better management of dis-functioning AVF and lower radiological test costs.

Introducción: El hiperparatiroidismo primario (HPTP) es un trastorno endocrino frecuente, caracterizado por hipercalcemia y elevación de la parathormona. La disminución del filtrado glomerular ( < 60ml/min) se mantiene en la guías como un criterio para la realización de la paratiroidectomía (PTX) en el HPTP asintomático. La influencia que tiene la PTX sobre la evolución de la función renal es controvertida. Objetivos: Analizar las características clínicas, analíticas e histológicas de los pacientes intervenidos por HPTP, así como la evolución de la función renal tras la PTX. Material y métodos: Estudio retrospectivo de 297 pacientes con HPTP remitidos a cirugía en un único centro entre 1998 y 2016. Los parámetros analíticos se determinaron en situación basal, a la semana y al año de la PTX. Resultados: La incidencia de PTX fue de 38 casos/millón/año. La edad media fue 60 ± 14 años y el 80,5% de los pacientes eran mujeres. El 65,3% estaban asintomáticos. La nefrolitiasis fue el hallazgo clínico más frecuente (33%) seguido de la afectación ósea (29,5%). Las indicaciones de PTX fueron: síntomas clínicos (34,7%), hipercalcemia > 11,2 mg/dl (27%), litiasis renal (13%), baja masa ósea (12%), edad < 50 años (11%) y disminución del filtrado < 60 ml/min (2,3%). En el diagnóstico de localización el spect-MIBI presentó una sensibilidad del 92% y la ecografía cervical del 70%. El 94,3% de los casos de HPTP eran debidos a un adenoma paratiroideo. Tras la PTX se objetivó normalización de los parámetros relacionados con el HPTP. Objetivamos un incremento significativo de la creatinina sérica (0,81 vs. 0,85 mg/dl, p < 0,001) desde la primera semana del postoperatorio y que se mantiene al año. Cuando comparamos los pacientes según el filtrado glomerular basal, encontramos que el deterioro de la función renal solamente fue significativo en pacientes con filtrado glomerular > 60 ml/min (creatinina sérica basal 0,77 mg/dl vs. creatinina sérica al año 0,81 mg/dl, p < 0,001). Conclusiones: El HPTP cursó asintomático en la mayoría de los pacientes intervenidos. La hipercalcemia y la nefrolitiasis fueron las indicaciones más frecuentes de paratiroidectomía en los pacientes asintomáticos. El scan-MIBI fue el método de localización más útil. La curación quirúrgica del HPTP se sigue de un deterioro de la función renal, que se mantiene desde la primera semana de la cirugía

ANTECEDENTES Y OBJETIVO: El abordaje multidisciplinar y el uso de ecografía doppler (ED) en la creación y vigilancia del acceso vascular (AV) puede mejorar la prevalencia y permeabilidad de las fístulas arteriovenosas (FAV) para hemodiálisis. El objetivo de este estudio es analizar el impacto de una nueva consulta multidisciplinar (CMD) de AV con ED de rutina. MATERIAL Y MÉTODOS: Evaluamos los resultados de la consulta de AV en 2014 (pre-CMD) y 2015 (CMD), antes y después de la implantación de un equipo multidisciplinar (cirujano vascular/nefrólogo) con ED de rutina en mapeo prequirúrgico y FAV prevalente. RESULTADOS: Se evaluaron 345 pacientes en 2014 (pre-CMD) y 364 pacientes en 2015 (CMD). En ambos periodos se realizó un número similar de cirugías, 172 vs. 198, p = 0,289, con tendencia a aumentar las cirugías preventivas de reparación de FAV en el periodo CMD, 17 vs. 29 (p = 0,098). En FAV de nueva creación (155 vs. 169), disminuyó la tasa de fallo primario en el periodo CMD, 26,4 vs. 15,3%, p = 0,015 y aumentó de forma no significativa la realización de FAV radiocefálicas distales, 25,8 vs. 33,2% (n = 40 vs. 56), p = 0,159. También aumentó la concordancia entre la indicación quirúrgica en la consulta y la cirugía realizada (81,3 vs. 93,5%, p = 0,001). En el periodo CMD se solicitaron menos exploraciones radiológicas desde la consulta, 78 vs. 35 (p < 0,001), con una reducción del gasto sanitario (81.716€ vs. 59.445€). CONCLUSIONES: El manejo multidisciplinar y la utilización del ED de rutina permiten mejorar los resultados de AV, con disminución de la tasa de fallo primario de FAV, más opciones de FAV distal nativa, mejor manejo de la FAV prevalente disfuncionante y menor coste en exploraciones radiológicas
