Prevalencia de acidosis metabólica en derivaciones ileales tras más de un año de la cistectomía radical y repercusiones metabólicas secundarias asociadas / Prevalence of metabolic acidosis in ileal diversions more than one year after radical cystectomy and associated secondary metabolic effects

Introducción y objetivo La acidosis metabólica (AM) es una alteración conocida en pacientes con derivaciones ileales. Es más frecuente en etapas tempranas postoperatorias y disminuye con el tiempo. Nuestro objetivo es determinar su prevalencia tras más de un año de seguimiento, analizar sus factores de riesgo y evaluar su impacto en diferentes perfiles metabólicos. Materiales y métodos Realizamos un estudio observacional entre enero de 2018 y septiembre de 2022 siguiendo las normas STROBE. La AM fue definida con valores de bicarbonato venoso <22mEq/l. Analizamos 133 pacientes con una media de seguimiento de 55,24±42,36 meses. Resultados Se identificaron 16 (12%) pacientes con AM. Los pacientes con y sin AM fueron comparables en edad, sexo y tiempo de seguimiento. El grupo con AM presentó una mayor tasa de anemia (68,75 vs. 19,65%; p<0,001) e insuficiencia renal (100 vs. 45,29%; p<0,001) y niveles venosos estadísticamente significativos mayores de creatinina, cloro, potasio, hormona paratiroidea y fósforo, pero menores valores de hemoglobina, filtrado glomerular, colesterol total, vitamina D, calcio y albúmina (todos p<0,05). El filtrado glomerular fue el único factor de riesgo independiente relacionado con la AM (OR: 0,914; IC 95%: 0,878-0,95; p<0,0001), demostrando una estrecha correlación con los valores de bicarbonato venoso (r=0,387; p<0,001). Conclusiones La AM es una alteración poco prevalente en derivaciones urinarias ileales transcurrido más de un año de la cistectomía, pero tiene implicaciones en el metabolismo hematológico, renal, proteico, lipídico y óseo. Aconsejamos su monitorización en pacientes con insuficiencia renal para poder realizar un diagnóstico y tratamientos precoces (AU)

Introduction and objective Metabolic acidosis (MA) is a well-known complication in patients with ileal urinary diversions. It is common in the early postoperative stages and decreases over time. Our objective is to investigate the prevalence of MA after more than one year of follow-up, identify the associated risk factors, and analyze its secondary metabolic consequences. Materials and methods We conducted an observational study between January 2018 and September 2022 following the STROBE guidelines. MA was defined as a serum bicarbonate level <22mEq/L. Finally, we analyzed 133 patients with a mean follow-up of 55.24±42.36 months. Results MA was observed in 16 (12%) patients. Patients with and without MA were comparable in age, sex, and follow-up time. The group with MA presented a higher rate of anemia (68,75% vs 19.65%, P<.001) and renal failure (100% vs 45.29%, P<.001), statistically significant higher levels of serum creatinine, chloride, potassium, parathyroid hormone, and phosphorus but lower serum values of hemoglobin, renal glomerular filtration rate, total cholesterol, vitamin D, calcium, and albumin (all P<.05). Renal glomerular filtration rate was the only independent risk factor related to the development of MA (OR: 0.914; 95% CI: 0.878-0.95; P<.0001), proving a close correlation with venous bicarbonate values (r=.387, P<.001). Conclusions MA is a little prevalent disorder in ileal urinary diversions more than one year after radical cystectomy is performed but it has secondary consequences on hematologic, renal, protein, lipid, and bone metabolism. We recommend to a close follow-up in patients with renal failure for early diagnosis and treatment (AU)

Mujer y urología: ¿cuál es la situación en España? / Women in urology: What is their current situation in Spain?

Objetivo Analizar la situación actual de las mujeres en la especialidad de Urología en España. Material y métodos Estudio descriptivo a partir de los resultados de una encuesta electrónica remitida entre febrero y abril de 2020 a través de la base de datos del grupo de Residentes y Jóvenes Urólogos (RAEU) de la Asociación Española de Urología (AEU). Se analizaron las características demográficas de la encuesta y los resultados de la misma. Resultados Se obtuvieron 257 respuestas, correspondientes a 210 mujeres (81,71%) y 47 hombres (18,29%) procedentes de 111 hospitales en total. Se obtuvieron diferencias estadísticamente significativas (p<0,001), con una mayor proporción de hombres en todas las categorías, excepto en el grupo de adjuntas y adjuntos jóvenes (29-39años; p=0,789) y en el de residentes mujeres frente a residentes hombres (p=0,814). En los hospitales con unidades subespecializadas se encontró un mayor número de hombres en todas, excepto en la unidad de suelo pélvico, en la que no se observó una diferencia estadísticamente significativa (p=0,06). Respecto a cargos de responsabilidad, en solo 7 de 111 hospitales había jefas de servicio. Conclusiones La presencia de las mujeres en la especialidad de Urología es cada vez mayor, debido mayoritariamente a las generaciones más jóvenes. Sin embargo, el acceso de estas mujeres a puestos de relevancia es anecdótica (AU)

Objective To analyze the current state of women in urology in Spain. Material and methods Descriptive study based on the results of an online survey sent between February and April 2020 through the database of the Residents and Young Urologists group (RAEU) of the Spanish Association of Urology (AEU). Demographic characteristics of the survey and its results were analyzed. Results In total, 257 responses were obtained from 210 women (81.71%) and 47 men (18.29%) belonging to 111 hospitals. Statistically significant differences were observed (P<.001) with a higher proportion of men in all categories except for the group of young female and male attendings (29-39 years, P=.789), and the group of female residents against male residents (P=.814). The number of men was higher in hospitals with subspecialty units except for the Pelvic Floor Unit, where no statistically significant difference was observed (P=.06). Regarding positions of responsibility, only 7 out of 111 hospitals had female department chiefs. Conclusions Women's representation in urology is increasing, mainly due to the younger generations. However, the access of these women to relevant positions is anecdotal (AU)

Acidosis metabólica tras cistectomía radical con derivación urinaria ileal. ¿Sabemos tanto como creemos? Revisión sistemática / Metabolic acidosis after ileal urinary diversion and radical cystectomy. Do we know as much as we believe? A systematic review

El contacto de la orina con la mucosa de la derivación urinaria (DU) tras la cistectomía radical (CR) produce diversos intercambios iónicos que promueven el desarrollo de la acidosis metabólica (AM). Esta alteración es una causa frecuente de reingresos y complicaciones a corto/largo plazo. Realizamos una revisión sistemática sobre la AM en CR con DU ileales, analizando su prevalencia, diagnóstico, factores de riesgo y tratamiento. Llevamos a cabo una revisión de la literatura de artículos publicados en Pubmed® y Cochrane Library antes de mayo de 2022 siguiendo las recomendaciones PRISMA. Se identificaron 421 artículos, de los cuales 25 cumplieron los criterios de inclusión sumando un total de 5.811 pacientes. Los estudios analizados demuestran mucha heterogeneidad en los criterios analíticos de diagnóstico y tratamiento utilizados, pudiendo sesgar los resultados de prevalencia. El desarrollo de la AM es multifactorial, siendo más frecuente su aparición durante el periodo postoperatorio temprano, especialmente en DU con segmentos ileales más largos, con mayor continencia urinaria y en pacientes con insuficiencia renal. La edad avanzada y la diabetes son factores de riesgo relacionados en periodos más tardíos. La AM es la causa más frecuente de segundos o más reingresos hospitalarios. La realización de profilaxis alcalinizante durante 3 meses en pacientes de riesgo podría mejorar estos resultados. Aunque la AM en DU ileales es una alteración conocida, esta revisión revela la necesidad de implementar criterios homogéneos de diagnóstico, monitorización y tratamiento, además de protocolizar estrategias de prevención/profilaxis en pacientes de riesgo (AU)

Urine contact with the mucosa of the urinary diversion (UD) after radical cystectomy (RC) produces different ion exchanges that favor the development of metabolic acidosis (MA). This phenomenon is a frequent cause of hospital readmission and short/long-term complications. We performed a systematic review of MA in RCs with ileal UD, analyzing its prevalence, diagnosis, risk factors and treatment. We systematically searched Pubmed® and Cochrane Library for original articles published before May 2022 according to PRISMA guidelines. A total of 421 articles were identified. We selected 25 studies that met the inclusion criteria involving 5811 patients. Obtaining precise data on the prevalence of MA is difficult, largely due to the heterogeneity of the diagnostic criteria used given the diversity of studies analyzed. Development of MA is multifactorial. In the early period, MA is more prevalent in patients with UD with longer ileal segments, better urinary continence, and impaired renal function. Age and diabetes are risk factors associated with MA in later periods. MA is the most common cause of second or more hospital readmissions. Prophylaxis with oral bicarbonate for three months in patients at risk could improve these results. Although MA after ileal UD is a well-known condition, this review highlights the need to implement homogeneous criteria for the diagnosis, follow-up, and treatment, in addition to protocolizing prevention/prophylaxis strategies in patients at risk (AU)
