Caracterización de pacientes con antecedente de colposuspensión de Burch que consultan en uroginecología / Characterization of patients with a background of Burch colposuspension consulting in urogynecology

INTRODUCCIÓN Y OBJETIVOS: La incontinencia de orina de esfuerzo (IOE) es una patología muy frecuente. El tratamiento estándar corresponde al uso de cintas medio uretrales. Dentro de las técnicas quirúrgicas clásicas se encuentra la colposuspensión de Burch (CSB), poco frecuente en la actualidad. El objetivo de este estudio es describir las características de las pacientes con antecedentes de una CSB que consultan en la unidad de Uroginecología. MÉTODOS: Revisión tipo transversal de los datos ingresados a la unidad de Uroginecología del Hospital Dr. Sótero Del Río desde 2007 al 2019. Análisis descriptivo de los antecedentes de las pacientes con antecedente de CSB. RESULTADOS: Durante el periodo analizado, 63 pacientes presentaban antecedentes de CSB. La edad promedio fue 68 años, 88% eran post menopáusicas, 60% fueron sometidas a histerectomía y 24% a cirugías por prolapso (POP). La paridad promedio fue 3 hijos, 15% tuvieron al menos un parto por fórceps. Un 51% consultó por IOE, 54% por vejiga hiperactiva (VH) y 56% por sensación de bulto o peso. El 38% consultó por incontinencia de orina mixta, 37% por IOE + POP y 41% por VH + POP. 22% fueron reoperadas, 16% por medio de TVT y 6% por TOT. CONCLUSIONES: El antecedente de CSB es infrecuente en nuestra población. Similar a lo descrito en la literatura, más de un 50% de las pacientes consultó por síntomas de recurrencia y por complicaciones como POP y VH. Próximos estudios deberían evaluar si el antecedente de CSB es un factor de riesgo de complicaciones quirúrgicas o recurrencia.

INTRODUCTION AND OBJECTIVES: Stress urinary incontinence (SUI) is a common pathology. The standard treatment corresponds to the mid urethral slings. Among the classic surgical techniques is Burch colposuspension (CSB), currently rare. The objective of this study is to describe the characteristics of the patients with a previous history of CSB who consult in the Urogynecology unit. METHODS: Cross sectional review of the data of all the patients admitted to the Urogynecology unit of the Dr. Sótero Del Río Hospital from 2007 to 2019. Descriptive analysis of the antecedents of the patients with a history of CSB. RESULTS: During the analyzed period, 63 patients had a history of CSB. The average age was 68 years. 88% were postmenopausal, 60% underwent hysterectomy, and 24% underwent prolapse (POP) surgery. The average parity was 3, 15% had at least one forceps delivery. 51% consulted for SUI, 54% for overactive bladder (OAB) and 56% for sensation of lump or weight. 38% consulted for mixed urine incontinence, 37% for SUI + POP and 41% for OAB + POP. 22% were reoperated, 16% through TVT and 6% through TOT. CONCLUSION: The history of CSB is infrequent in our population. Similar to that described in the literature, more than 50% of the patients consulted for recurrence symptoms and complications such as POP and OAB. Future studies should assess whether a history of CSB is a risk factor for surgical complications or recurrence.

Impact of COVID-19 on clinical practice, income, health and lifestyle behavior of Brazilian urologists

ABSTRACT Objectives To evaluate the impact of COVID-19 on clinical practice, income, health and lifestyle behavior of Brazilian urologists during the month of April 2020. Materials and Methods A 39-question, web-based survey was sent to all urologist members of the Brazilian Society of Urology. We assessed socio-demographic, professional, health and behavior parameters. The primary goal was to evaluate changes in urologists' clinical practice and income after two months of COVID-19. We also looked at geographical differences based on the incidence rates of COVID-19 in different states. Results Among 766 urologists who completed the survey, a reduction ≥ 50% of patient visits, elective and emergency surgeries was reported by 83.2%, 89.6% and 54.8%, respectively. An income reduction of ≥ 50% was reported by 54.3%. Measures to reduce costs were implemented by most. Video consultations were performed by 38.7%. Modifications in health and lifestyle included weight gain (32.9%), reduced physical activity (60.0%), increased alcoholic intake (39.9%) and reduced sexual activity (34.9%). Finally, 13.5% of Brazilian urologists were infected with SARS-CoV-2 and about one third required hospitalization. Urologists from the highest COVID-19 incidence states were at a higher risk to have a reduction of patient visits and non-essential surgeries (OR=2.95, 95% CI 1.86 - 4.75; p< 0.0001) and of being infected with SARS-CoV-2 (OR=4.36 95%CI 1.74-10.54, p=0.012). Conclusions COVID-19 produced massive disturbances in Brazilian urologists' practice, with major reductions in patient visits and surgical procedures. Distressing consequences were also observed on physicians' income, health and personal lives. These findings are probably applicable to other medical specialties.

Exploring Urological Experience in the COVID-19 Outbreak: American Confederation of Urology (CAU) Survey

ABSTRACT Purpose: To explore the current situation faced by Latin American urology departments during the COVID-19 Outbreak in terms of knowledge, actions, prioritization of urology practices, and implementation of internal clinical management protocols for inpatients and outpatients. Material and Methods: A non-validated, structured, self-administered, electronic survey with 35 closed multiple choice questions was conducted in Spanish, Portuguese, Italian, and English and Deutsch versions from April 1st to April 30th, 2020. The survey was distributed through social networks and the official American Confederation of Urology (CAU) website. It was anonymous, mainly addressed to Latin American urologists and urology residents. It included 35 questions exploring different aspects: 1) Personal Protective Equipment (PPE) and internal management protocols for healthcare providers; 2) Priority surgeries and urological urgencies and 3) Inpatient and outpatient care. Results: Of 864 surveys received, 846 had at least 70% valid responses and were included in the statistical analyses. Surveys corresponded to South America in 62% of the cases, Central America and North America in 29.7%. 12.7% were residents. Regarding to PPE and internal management protocols, 88% confirmed the implementation of specific protocols and 45.4% have not received training to perform a safe clinical practice; only 2.3% reported being infected with COVID-19. 60.9% attended urgent surgeries. The following major uro-oncologic surgeries were reported as high priority: Radical Nephrectomy (RN) 58.4%, and Radical Cystectomy (RC) 57.3%. When we associate the capacity of hospitalization (urologic beds available) and percentage of high-priority surgery performed, we observed that centers with fewer urological beds (10-20) compared to centers with more urological beds (31-40) performed more frequently major urologic cancer surgeries: RN 54.5% vs 60.8% (p=0.0003), RC 53.1% vs 64.9% (p=0.005) respectively. Conclusions: At the time of writing (May 13th 2020) our data represents a snapshot of COVID-19 outbreak in Latin American urological practices. Our findings have practical implications and should be contextualized considering many factors related to patients and urological care: The variability of health care scenarios, institutional capacity, heterogeneity and burden of urologic disease, impact of surgical indications and decision making when prioritizing and scheduling surgeries in times of COVID-19 pandemic.

Emergency Surgery in Urology during the COVID-19 Pandemic

ABSTRACT Proposal: To highlight the indications for emergency surgery during the 2019 Coronavirus pandemic (COVID-19) that support recommendations published in midMarch 2020 by the American Confederation of Urology on its website. Materials and Methods: A bibliographic search was conducted in PubMed and Cochrane Library to perform a non-systematic review, using key words: Urology, Emergency and COVID-19, to determine recommendations for patients that should receive emergency care due to urological pathology. Results: The main recommendations and protocols in the management of different urological emergencies during the COVID-19 pandemic are reviewed and discussed. Conclusions: We are living a new condition with the COVID-19 pandemic, which obliges urologists to conform to the guidelines that appear on a daily basis formulated by multidisciplinary surgical groups to manage urological emergencies. Consequently, in this time of health crisis, we must adapt to the resources available, implementing all biosecurity measures to protect patients and all health personnel who are in charge of patient management.

Intraoperative serious complications of laparoscopic urological surgeries: a single institute experience of 4, 380 procedures

ABSTRACT This study aimed to share a single institute experience of 4,380 procedures about in-traoperative serious complications of laparoscopic urological surgeries. From January 2005 to December 2013, 4,380 cases of laparoscopic urological surgeries were recruited in our department. The distribution, incidence, and characteristics of intraoperative serious complications were retrospectively sorted out and analyzed. The surgeries were divided into three groups: very difficult (VD), difficult (D), and easy (E). The com¬plication at Satava class II was defined to be serious. One hundred thirty one cases with intraoperative serious complications were found (3.0%). The incidence of these complications was significantly increased along with the difficulty of the surgeries (P<0.05). The highest morbidity of serious complication belonged to total cystectomy with a ratio of about 17% as compared with other surgeries (P<0.05). The types of these complications included small vascular injury demanding blood transfusion (101 cases, 77.1%), large vascular (venous and artery) injury (16 cases), hypercapnia & acidosis (8 cases), and organ injury (6 cases). The cases of conversion to open surgery were 37 (≤1%). There was no significant difference in the rates of conversion to open surgery among the three groups (P>0.05). The overall tendency of the intraoperative serious complications was decreasing with the time from 2005 to 2013. In conclusion, through standardized training including improving the surgical technique, being familiar with the anatomic relationship, and constantly summarizing the experience and lessons, laparoscopic surgery could be safe and effective with not only minimal invasion but also few complications.

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

Occult urinary incontinence treatment: systematic review and meta-analysis-brazilian guidelines / Tratamento de incontinência urinária oculta: revisão sistemática e metanálise - diretrizes brasileiras

Abstract Objective To evaluate if performing anti-incontinence procedures during surgical anterior and/or apical prolapse correction in women with asymptomatic urinary incontinence (UI) may prevent stress urinary incontinence (SUI) postoperatively. Methods We have performed a systematic review of articles published in the PubMed, Cochrane Library, and Lilacs databases until March 31, 2016. Two reviewers performed the data collection and analysis, independently. All of the selected studiesweremethodologically analyzed. The results are presented as relative risk (RR), with a 95% confidence interval (CI). Results After performing the selection of the studies, only nine trials fulfilled the necessary prerequisites. In the present review, 1,146 patients were included. Altogether, the review included trials of three different types of anti-incontinence procedures. We found that performing any anti-incontinence procedure at the same time of prolapse repair reduced the incidence of SUI postoperatively (RR = 0.50; 95% CI: 0.28-0.91). However, when we performed the analysis separately by the type of anti-incontinence procedure, we found different results. In the subgroup analysis with midurethral slings, it is beneficial to perform it to reduce the incidence of SUI (RR = 0.08; 95% CI: 0.02-0.28). On the other hand, in the subgroup analysis with Burch colposuspension, there was no significant difference with the control group (RR = 1.47; 95% CI: 0.28-7.79]). Conclusion Performing any prophylactic anti-incontinence procedure at the same time as prolapse repair reduced the incidence of SUI postoperatively. The Burch colposuspension did not show any decrease in the incidence of SUI postoperatively.

Resumo Objetivo: Avaliar se a realização de procedimentos anti-incontinência durante a correção cirúrgica do prolapso anterior e/ou apical em mulheres assintomáticas para incontinência urinária (IU) pode prevenir a incontinência urinária de esforço (IUE) no pós-operatório. Métodos: Foi realizada uma revisão sistemática dos artigos publicados nas bases de dados PubMed, Cochrane Library e Lilacs até o dia 31 de março de 2016. Dois revisores realizaram a coleta e a análise de dados, de forma independente. Todos os estudos selecionados foram analisados metodologicamente. Os resultados estão apresentados como risco relativo (RR), com 95% de intervalo de confiança (IC). Resultados: Após a seleção do estudo, apenas nove estudos preencheram os prérequisitos necessários. Nesta revisão, 1.146 pacientes foram incluídos. No total, a revisão incluiu ensaios de três tipos diferentes de procedimentos anti-incontinência. Descobrimos que realizar qualquer procedimento anti-incontinência ao mesmo tempo que o reparo do prolapso reduziu a incidência de IU no pós-operatório (RR = 0,50; IC 95%: 0,28-0,91). No entanto, quando fizemos a análise separadamente pelo tipo de procedimento antiincontinência, encontramos resultados diferentes. Na análise de subgrupos com slings miduretrais, é benéfico realizá-lo para reduzir a incidência de IU (RR = 0,08; IC 95%: 0,02- 0,28). Por outro lado, na análise de subgrupo com colposuspensão de Burch, não houve diferença significativa com o grupo controle (RR = 1,47; IC 95%: 0,28-7,79]). Conclusão: A realização de qualquer procedimento profilático anti-incontinência ao mesmo tempo que o reparo do prolapso reduziu a incidência de IUE no pós-operatório. A colposuspensão de Burch nãomostrou diminuição na incidência de IUE no pós-operatório.

Cirugía urológica en pacientes de 80 años y más: ¿es la edad un factor de riesgo para el desarrollo de complicaciones postoperatorias? / Urological surgery in patients 80 years and older: is age a risk factor for the development of postoperative complications?

La expectativa de vida ha ido aumentando en Chile y en el mundo, lo que ha causado un gran impacto a nivel del número de cirugías que se realiza en la población añosa. El objetivo de este trabajo es describir la experiencia de nuestro centro en cirugías urológicas en pacientes mayores de 80 años y analizar que factores aumentan el riesgo de complicaciones postquirúrgicas.Materiales y método: Análisis retrospectivo de 138 cirugías urológicas realizadas en 120 pacientes mayores de 80 años, durante los años 2000 a 2012. Se obtuvo información sociodemográfica, riesgo quirúrgico (ASA), tipo y duración de cirugía realizada, complicaciones post-operatorias (escala de Clavien) y tiempo de hospitalización. Los datos obtenidos fueron analizados mediante el programa SPSS v17. Se realizó análisis multivariado y se estableció el riesgo relativo para el desarrollo de complicaciones. Se consideró signi ficativo p<0,05. Resultado: La edad promedio de los pacientes fue de 84+/-3.7 años, 86.2 por ciento fueron hombres. El 96.7 por ciento presentaba algún tipo de comorbilidad, con predominio de hipertensión arterial (60,84 por ciento) y diabetes mellitus tipo 2 (24,16 por ciento). La mayoría de las intervenciones fue de complejidad intermedia (77.27 por ciento), donde la anestesia regional (56,8 por ciento) y la vía endo urológica (84,78 por ciento) fueron las más utilizadas, con un tiempo operatorio promedio de 62+/-52.4 minutos. El riesgo quirúrgico prevalente fue ASA2 (62.7 por ciento). El promedio de hospitalización fue de 2,8+/-2.7 días. El 15.21 por ciento de los pacientes presentó algún tipo de complicación, con predominio de clasifi cación tipo 1 de Clavien (38 por ciento). En el análisis multivariado se evidenció como factores de riesgo signi ficativos para complicaciones, edad mayor a 90 años (p=0.03), presencia de insu ciencia renal (p=0.01), portar 4 o más comorbilidades (p=0.04), cirugía mayor a 3 horas (p=0.03) y tener riesgo quirúrgico ASA3 (p=0.04)...

Life expectancy has been increasing in Chile and in the World. This has caused a great impact over the number of surgeries being performed in the elderly population. The aim of this paper is to describe the experience of our center in urological surgery in patients older than 80 years and analyze which factors increase the risk of postoperative complications.Materials and methods: Retrospective analysis of 138 urological surgeries performed in 120 patients older than 80 years, during the years 2000-2012. Sociodemographic information, surgical risk (ASA), type and duration of surgery, postoperative complications (Clavien scale) and length of hospitalization was obtained. The data were analyzed using SPSS v17. Multivariate analysis was performed and the relative risk for developing complications was established. Signi cance was p <0.05. Average age of the patients was 84 +/- 3.7 years, 86.2percentwere men. The 96.7 percenct had some kind of comorbidity, with prevalence of hypertension (60.84 percent) and diabetes mellitus type 2 (24.16 percent). Most of the interventions was of intermediate complexity (77.27percent), where regional anesthesia (56.8 percent) and endourological aproach (84.78 percent) were the most used, with average operative time of 62 +/- 52.4 minutes. Most common Surgical risk was ASA2 (62.7 percent). Average hospital stay was 2.8 +/- 2.7 days. 15.21 percent of patients had some type of complication, with a predominance of type 1 Clavien classication (38 percent). The multivariate analysis showed signi cant risk factors for complications: age greater than 90 years (p = 0.03), renal failure (p = 0.01), carrying 4 or more comorbidities (p = 0.04), surgery Langer than 3 hours (p = 0.03) and ASA3 surgical risk (p =.04). No mortality was reported in our series. In this study, although most of our patients underwent endourological procedures, we evidence that surgery in patients older than 80 years is feasible...

Uso de segmentos intestinales en urología: seguimiento a 5 años / Use of intestinal segments im urology: a 5-year follow-up

Introducción: Desde hace más de 50 años se utilizan segmentos intestinales en urología para aumentar o reemplazar vejigas, reemplazar uréteres y derivar la orina a través de segmentos de intestino aislados. Objetivo: Describir la casuística de cirugías con uso de segmentos intestinales y a los menos 5 años de seguimiento completo, realizada en el Servicio de Urología del HCVB, sus principales indicaciones, técnicas y complicaciones. Materiales y métodos: Estudio observacional retrospectivo. Se revisaron 291 fichas de pacientes operados con uso de un segmento intestinal, con más de 5 años de seguimiento posterior, evaluando diagnóstico etiológico, técnica utilizada para enterocistoplastia, reservorio, neoimplante, ostomía y sus respectivas complicaciones a 3 meses, 5 años y final de seguimiento. Resultados: Se efectuaron 301 intervenciones (291 pacientes + 10 reinterveciones con uso de nuevos segmentos intestinales). Se seleccionan 111 casos (36,8 por ciento) en los que se dispone de seguimiento superior a 5 años. La principal indicación fue hiperactividad neurogénica del detrusor con 39 casos (35,14 por ciento); 30 casos (27,03 por ciento) de cistopatía intersticial; 16 casos (14,41 por ciento) de cáncer vesical; 11 casos (9,91 por ciento) de vejiga hiperactiva idiopática. Del total 70 fueron mujeres (63,06 por ciento), 41 fueron hombres (36,94 por ciento). La intervención más frecuente es la enterocistoplastia detubulizada de ampliación (79,28 por ciento), seguido por el reservorio ortotópico (10,9 por ciento). La elección del segmento intestinal se basó principalmente en la factibilidad anatómica, el íleon detubulizado en parche en U a la cara posterior para las enterocistoplastias de ampliación y el uso de segmentos de intestino grueso para fabricaciones deostomías continentes.La mayor cantidad de complicaciones se presenta en el periodo entre los 3 meses y 5 años de seguimiento (23 de 111 casos)

Introduction: Since over 50 years intestinal segments have been used in urology to augment or replace bladders, ureters and divert urine through isolated intestinal segments. Objective: The purpose of this article is to describe the use of intestinal segments in urological surgeries performed in the urological service of the HCVB, with a minimum of 5 years of follow-up. Indication, technique and complications are analyzed. Materials ad methods: It is an observational and retrospective study. 291 clinical charts of patients with use of intestinal segments in their surgery and more than 5 years of follow-up were analyzed. We evaluated diagnosis, technique used for bladder augmentation, reservoir, neoimplantation, stoma and their complications at a 3rd month, 5th year and end to follow-up moments. Results: A total of 301 surgeries were performed (291 patients + 10 revisions with use of new intestinal segments). 111 cases (36,8 percent) had a 5-year follow-up. Main indication for surgery was neurogenic detrusor hiperactivity in 39 cases (35,14 percent); there were 30 interstitial cystitis cases (27,03 percent); 16 cases ob bladder cancer (14,41 percent); 11 cases of idiopathic hyperactive bladder (9,91 percent). From the total group70 (63,06 percent) were female and 41 (36,94 percent) male. The most frequent surgery performed was the detubularized bladder augmentation (79,28 percent), followed by the orthotopic reservoir (19,9 percent).Election of the intestinal segment was based principally in technical feasibility, U-shaped detubularized ileum as a posterior patch for bladder augmentations and colon for continent stomas. Most complications occur between the 3rd month and the 5th year of follow-up (23 of 111 cases), needing non- surgical treatment in 12 cases, surgery in 6 cases and 3 patients stood in a life-risk situation. Continence is good in 88,7 percent of the cases. Conclusions: The use of intestinal segments for patch, reservoir and

Cirugía urológica laparoscópica realizada por residentes de urología en formación / Laparoscopic urologic surgery, carried out by an ½in training¼ urology resident

La cirugía laparoscópica es parte de la urología actual. Hoy en día se desarrolla una amplia variedad de procedimientos por este medio. Considerando la curva de aprendizaje, existe una dificultad esperable en lograr un buen entrenamiento de residentes en formación. El objetivo del presente trabajo es comunicar la experiencia en el entrenamiento laparoscópico de los residentes de urología en un centro universitario. Se revisaron los registros clínicos de los pacientes con cirugía urológica laparoscópica en el período comprendido entre julio 1999 y agosto 2003. Se registraron: datos demográficos, antecedentes, indicación quirúrgica, cirujano, información de la cirugía, evolución postoperatoria. En el período de estudio se realizaron 128 cirugías urológicas laparoscópicas, de las cuales 20 (16 porciento)fueron realizadas por residentes de urología en formación con experiencia laparoscópica en cirugía generaly/o en cirugía experimental y con ayuda directa de urólogos laparoscopistas. Diez pacientes de sexomasculino (50 porciento). La edad promedio fue de 49 años (r: 19-74). Se realizaron 7 nefrectomías (4 radicalespor tumor y 3 por atrofia renal hidronefrótica), 4 quistectomías renales, 3 linfadenectomías lumboaórticas, 3 biopsias renales, 1 nefroureterectomía, 1 suprarrenalectomía, 1 instalación de catéter de peritoneodiálisismás adherenciolisis. El tamaño promedio de los tumores renales fue de 6,3 cm. El tiempo operatorio promedio fue de 108 minutos (r: 30-240) y el sangrado de 74 cc (r: 0-800 cc). Se presentó una complicación grave (paciente con hígado cirrótico como hallazgo intraoperatorio que presentó hemorragia y coagulopatía). El alta fue a los 2,7 días promedio (r: 1-14). No se registraron conversiones. La docencia directa en cirugía laparoscópica permite obtener resultados que se comparan favorablemente a los comunicados en la literatura.

Egresos hospitalarios por patología genitourinaria en Chile: segunda parte / Hospital discharges by pathologies of the genitourinary tract in Chile: second part

Utilizando el Boletín de Egresos Hospitalarios del MINSAL para los años 1993, 1996 y 2001 se analizaron aquellos códigos correspondientes a Patologías del Sistema Génitourinario (PGU) según el sistemade Clasificación Internacional de Enfermedades OMS CIE-9 y CIE-10, caracterizándolos según su composición geográfica y demográfica.En 1993, 1996 y 2001 se registraron en Chile: 1.404.478, 1.441.374 y 1.566.187 egresos hospitalarios, respectivamente. Los egresos por PGU en esos años fueron 62.978, 70.207 y 64.648, lo que correspondea 4,48 porciento, 4,87 porciento y 4,13 porciento de los egresos hospitalarios totales para ese año. La ITU, HPB, litiasis y fimosisse mantienen como las patologías más prevalentes que requirieron hospitalización. Durante el año 2001,se observó una disminución entre 6 porciento y 7 porciento de los egresos por infección urinaria. Destaca el comportamientode los egresos por cánceres urológicos, los que fueron 4.129 en 1993, 5.206 en 1996 y 6.715 en 2001. Esto corresponde a 6,6 porciento, 7,5 porciento y 10,4 porciento del total de egresos por PGU para cada año respectivo. La patología génitourinaria continúa siendo una contribución menor al total de egresos hospitalarios en el país. Destaca la disminución en el número de egresos por infección urinaria registrado el año 2001. Además, es posible observar un aumento sostenido de los egresos por cáncer urogenital durante estos 8 años de seguimiento.
