RESUMO

OBJECTIVES: Report our experience with the use of contrast-enhanced serial voiding urosonography (SVU) for posterior urethral valve (PUV) patient diagnosis and management. MATERIAL AND METHODS: Descriptive retrospective study in 0- to 14-year-old patients with suspected PUV at SVU performed as a first contrast-enhanced urinary tract test with subsequent cystoscopic study. Variables were analyzed using SPSSv22. RESULTS: 18 patients were studied (median age: 6 months). Most patients (15) presented posterior urethral dilatation (mean diameter: 9.56 mm) and a >2 mm gap between proximal and distal urethra. 13 cases had bladder thickening and 9 had VUR. 15 PUV cases, 1 case of distal urethral mucocele, and 1 case of bladder diverticulum obstructing the urethra were diagnosed. Complete PUV resection was performed in 10 patients (66.6%) at the first cystoscopy. The control SVU detected one case of recurrence due to persistence of posterior urethral dilatation. The recurrence case and the 5 incomplete resection cases were treated with a second cystoscopy and resection. The youngest patients required a third resection and cutting balloon dilatation due to residual stenosis. Mean creatinine levels at diagnosis were 0.28 mg/dl. CONCLUSIONS: Serial voiding urosonography (SVU) is a useful complementary test in pediatric patients with posterior urethral valve. Its dynamic nature and its advantages - absence of irradiation, safety, and high sensitivity - make it an ideal imaging test for PUV diagnosis and follow-up.


OBJETIVOS: Comunicar nuestra experiencia con la utilización de la urosonografía miccional seriada (UMS) para el diagnóstico y manejo de pacientes con válvulas de uretra posterior (VUP). MATERIAL Y METODOS: Estudio retrospectivo descriptivo en pacientes entre 0 a 14 años con sospecha de VUP en UMS realizada como primera prueba contrastada de la vía urinaria y con estudio cistoscópico posterior. Las variables se analizaron utilizando SPSSv22. RESULTADOS: Fueron estudiados 18 pacientes (edad mediana de 6 meses). La mayoría de los pacientes (15) presentaban dilatación de la uretra posterior (diámetro medio de 9,56 mm) y diferencia entre uretra proximal y distal mayor de 2 mm. Trece casos tenían engrosamiento vesical y 9 RVU. Se diagnosticaron 15 casos de VUP, 1 caso de mucocele de uretra distal y 1 divertículo vesical que obstruía uretra. Se consiguió resección completa de las VUP en 10 pacientes (66,6%) en la primera cistoscopia. La UMS de control detectó un caso de resección incompleta por persistencia de dilatación de uretra posterior. Este caso y los 5 conocidos con resección incompleta se sometieron a una segunda cistoscopia y resección. El menor de los pacientes requirió una tercera resección y dilatación con balón de corte por estenosis residual. La creatinina media al diagnóstico fue 0,28 mg/dl. CONCLUSIONES: La urosonografía miccional seriada (UMS) es una prueba complementaria útil en pacientes pediátricos con válvulas de uretra posterior. Su carácter dinámico y ventajas: ausencia de irradiación, seguridad y alta sensibilidad; la convierten en una prueba de imagen ideal para el diagnóstico y seguimiento de VUP.

RESUMO

OBJECTIVES: To present our experience of 23 years in the treatment of varicocele by embolization in pediatric age. MATERIAL AND METHODS: Observational descriptive study of all patients with varicocele treated by embolization after phlebography, by indication of the pediatric surgery service between 1995 and 2017. We performed descriptive statistical analysis and comparison between pain and testicular asymmetry before and after treatment (SPSSv22). RESULTS: Embolization was performed in 113 patients with left varicocele. The mean age of diagnosis was 12.4 years (5.2-15.5). The main clinical manifestations were: incidental finding (46.7%), increase in scrotal volume (28%) and testicular pain (15.9%). 61.5% were grade 3 and 38.5% grade 2. The selective embolization procedure was performed at an average age of 13.6 years (8-18). There were no serious complications of the procedure or reactive hydrocele. The overall success rate of endovascular treatment was 93.8%. In 85 patients (75.2%) a single procedure was performed and in 21, two procedures (18.6%). Only 4 patients required surgical intervention. The pain disappeared in all cases in which it presented and the testicular asymmetry decreased from 44.7% pre-treatment to 21.2% post-treatment (p<0.05). CONCLUSIONS: Endovascular treatment through embolization allows a selective varicocele management, after venous mapping, with an adequate effectiveness, without altering the arterial flow of the testicle or producing hydrocele. It is a minimally invasive treatment that could be considered the first choice in varicoceles of children and adolescents.


OBJETIVOS: Presentar nuestra experiencia de 23 años en el tratamiento del varicocele mediante embolización en la edad pediátrica. MATERIAL Y METODOS: Estudio descriptivo observacional de todos los pacientes con varicocele tratados mediante embolización previa flebografía, por indicación del servicio de cirugía pediátrica entre los años 1995 a 2017. Realizamos análisis estadístico descriptivo y comparación entre dolor y asimetría testicular previa y posterior al tratamiento (SPSSv22). RESULTADOS: Se realizó embolización en 113 pacientes con varicocele izquierdo. La edad media de diagnóstico fue de 12,4 años (5,2-15,5). Las manifestaciones clínicas principales fueron: hallazgo incidental (46,7%), aumento de volumen escrotal (28%) y dolor testicular (15,9%). El 61,5% eran de grado 3 y el 38,5% de grado 2. El procedimiento de embolización selectiva se realizó a una edad media de 13,6 años (8-18). No se presentaron complicaciones graves del procedimiento ni hidrocele reactivo. En 85 pacientes (75,2%) se realizó un único procedimiento y en 21, dos procedimientos (18,6%). La tasa de éxito global del tratamiento endovascular fue de 93,8%. Solo 4 pacientes requirieron intervención quirúrgica. El dolor desapareció en todos los casos en que se presentaba y la asimetría testicular disminuyó del 44,7% pretratamiento al 21,2% postratamiento (p<0,05). CONCLUSIONES: El tratamiento endovascular mediante embolización permite un manejo selectivo del varicocele, previo mapeo venoso, con una adecuada efectividad, sin alterar el flujo arterial del testículo ni producir hidrocele. Es un tratamiento poco invasivo que se puede considerar de primera elección en varicoceles de niños y adolescentes.

RESUMO

OBJECTIVES: To assess the utility of a new modality of video-urodynamic for study of lower urinary tract dysfunction and other uropathies in kids, replacing voiding cystourethrography by echo-enhanced cystosonography, without ionizing radiations. MATERIAL AND METHODS: Prospective study with simultaneous performance of filling cystometry and cystosonography in 43 kids during the last two years. The sonographic contrast was infused trough the urodynamic catheter. RESULTS: 18 girls and 25 boys, with an average age of 6.18 years (between 2 months and 14 years). The most frequent indication was micturition disfunction in boys and vesicoureteral reflux follow-up in girls. 60,5% presented urodynamic alterations, predominating low bladder accommodations (N = 9), mixed detrusor overactivity (N = 5) and bladder sphincter dyssynergia (N = 4). 15 children had vesicoureteral reflux: 8 passive, 5 active (associated with contractile activity of the detrusor or in the voiding phase) and two mixed. Urethral pathology was seen in two males (urethral valves and stenosis) and two girls (spinning top urethra). A statistically significant relationship was found between the presence of vesicoureteral reflux and other variables: bladder capacity (t = 4.98; p <0.005), detrusor activity (t = 3; p = 0.005), sex (t = 2.543; p = 0.015) and high post-void residual volume (t = 3.75; p <0.005), so that it was more frequent in girls with big bladders, with detrusor activity and high post-void residue. CONCLUSIONS: Cystosonography can replace conventional cystourethrography as an imaging test associated with urodynamics. With this type of exploration we have been able to indicate the treatment to our patients, subjecting them to a single catheterization and without exposing them to ionizing radiation.


OBJETIVOS: Valorar la utilidad de una nueva modalidad de videourodinamia sin radiaciones ionizantes en el estudio de disfunciones miccionales y otras uropatías en niños, sustituyendo cistouretrografía miccional seriada por cistosonografía o urosonografía miccional. MATERIAL Y METODOS: Estudio prospectivo con realización simultánea de cistomanometría de llenado y cistosonografía en 43 niños durante los dos últimos años. El contraste sonográfico fue infundido a través del catéter de urodinamia. RESULTADOS: 18 niñas y 25 niños, con edades de entre 2 meses y 14 años (media de 6,18 años). La indicación más frecuente en los varones fue disfunción miccional y en las niñas seguimiento de reflujo. El 60,5% presentaba alteraciones urodinámicas, predominando baja acomodación vesical (N = 9), hiperactividad del detrusor mixta (N = 5) y disinergia vésico-esfinteriana (N = 4). 15 niños tenían reflujo: 8 pasivos, 5 activos (asociados a actividad contráctil del detrusor o en fase miccional) y dos mixtos. Se vio patología uretral en dos varones (valvas de uretra posterior y estenosis uretral) y dos niñas (uretra en peonza). Se encontró relación estadísticamente significativa entre presencia de reflujo vesicoureteral y otras variables: capacidad vesical (t = 4,98; p <0,005), actividad del detrusor (t = 3; p = 0,005), sexo (t = 2,553; p = 0,015) y residuo postmiccional alto (t = 3,75; p <0,005), siendo más frecuente en niñas con vejigas grandes, con actividad del detrusor y residuo postmiccional alto. CONCLUSIONES: La UMS puede sustituir a la cistouretrografía convencional como prueba de imagen asociada a la urodinamia. Con este tipo de exploración hemos podido indicar un tratamiento a nuestros pacientes, sometiéndolos a un único sondaje y sin exponerlos a radiaciones ionizantes.

RESUMO

Introducción: En esta serie queremos analizar la eficacia diagnóstica de la urosonografía miccional seriada (UMS) con contraste de segunda generación, asociado a tecnología en modo armónico y específica para contraste, en el estudio de la vía urinaria en pediatría: diagnóstico y seguimiento de RVU, y también de anomalías uretrales, principalmente de las válvulas de la uretra posterior (VUP). Pacientes y métodos: Se realizó, previo consentimiento informado, estudio prospectivo con urosonografía con contraste de 2.ª generación (microburbujas de hexafluoruro de azufre, SonoVue®) en el periodo comprendido entre noviembre de 2014 a octubre de 2015 (un año) en pacientes pediátricos con sospecha de RVU, o alteración de la vía urinaria inferior (VUP). En pacientes con alta sospecha de RVU, y en los casos de VUP, se realizó además cistouretrografía miccional (CUMS) simultánea. Resultados: Fueron estudiados 40 pacientes (80 unidades renales) de entre 2 meses y 13 años (mediana 14 meses). La indicación de la prueba fue: sospecha de RVU (36 pacientes, grupo A) y seguimiento de VUP (4 pacientes, grupo B). Se correlacionó con CUMS en 16 pacientes (12 casos con alta sospecha de RVU en el grupo A y con los 4 casos de VUP del grupo B). La visualización de la uretra fue adecuada en los casos de dilatación o estenosis uretral. En 3 de estos pacientes con RVU bilateral en UMS en la CUMS solo se apreciaba de forma unilateral en 2 de los casos y sin RVU en uno; κ = 0,73. Discusión: Hemos comprobado que la visualización de la uretra ya no es una limitación, y que la UMS puede ser superior a la CUMS convencional en el diagnóstico del RVU


Introduction: In this series, we analyse the diagnostic efficacy of serial voiding urosonography (VUS) with second-generation contrast, combined harmoniously and specifically with contrast technology, in the examination of the urinary tract in children. This examination includes the diagnosis and follow-up for vesicoureteral reflux (VUR) and urethral disorders, mainly those of the posterior urethral valve (PUV). Patients and methods: After obtaining informed consent, a prospective study was conducted using urosonography with second-generation contrast (sulphur hexafluoride microbubbles, SonoVue®) from November 2014 to October 2015 (1 year) in paediatric patients with suspected VUR or PUV impairment. For patients with a high suspicion of VUR and in cases of PUV, we also conducted simultaneous voiding cystourethrography (VCUG). Results: We studied 40 patients (80 renal units) between the ages of 2 months and 13 years (median age, 14 months). The indication for the test was a suspected VUR (36 patients, group A) and PUV follow-up (4 patients, group B). The test was correlated with VCUG in 16 patients (12 cases with high suspicion of VUR in group A and with 4 cases of PUV in group B). The visualisation of the urethra was appropriate in cases of dilation or urethral stricture. For 3 of these patients with bilateral VUR demonstrated in the serial VUS, the VCUG showed only unilateral VUR in 2 of the patients and no VUR in 1 of the patients (κ = .73). Discussion: We have shown that the visualisation of the urethra is no longer a limitation and that serial VUS can be superior to conventional VCUG in diagnosing VUR

RESUMO

Objetivos. Evaluar el desconocimiento social acerca del riesgo de aspiración de frutos secos y su relación con la profesión que ocupan sus padres. Material y métodos. Desde enero 2013 a enero 2014 se distribuyó una encuesta autodiseñada a 247 padres de pacientes menores de 14 años ingresados en nuestro centro, independientemente del motivo de ingreso. Para el análisis se calculó la significación estadística mediante intervalos de confianza (IC). Se valoró el desconocimiento de este problema en función del nivel de estudios extrapolado a partir de la ocupación de los encuestados mediante el test de Chi-cuadrado de Pearson. Resultados. 247 padres respondieron a la encuesta. El 60,3% (IC95% 54,1-66,2%) confirmó que en las fiestas de cumpleaños a las que asistían sus hijos había frutos secos. El 30,4% (IC95% 25-36,4%) afirmó que en las guarderías de sus hijos se realizaban celebraciones con frutos secos. El 42,1% (IC95% 36,1-48,3%) creía que los frutos secos no suponían en absoluto un peligro para sus hijos pequeños. El nivel de estudios extrapolado de los encuestados resultó independiente en la edad de administración de frutos secos (χ²=10,721, p=0,295), aunque sí influyó en el desconocimiento de la peligrosidad de los frutos secos (41,2% (IC 95% 30,3-53%) de los encuestados con ocupaciones que exigían tener estudios superiores frente al 55,4% (IC 95% 42,4-67,6%) de aquellas ocupaciones que requerían un menor nivel de estudios (χ²=14,678, p=0,002)). Conclusiones. Independientemente de la ocupación, existe un desconocimiento generalizado relativo a la edad de introducción de los frutos secos en la dieta. Se precisan más campañas de prevención dada la incidencia y gravedad del riesgo de aspiración, por lo que las autoridades responsables deberían tomar partido en la concienciación pública de este problema


Objectives. To evaluate the social awareness of the risk of nuts aspiration and the relationship with the occupation of parents. Material and methods. From January 2013 to January 2014, a self-designed survey was distributed to 247 parents of patients under 14 years admitted to our centre, regardless of the reason for admission. The statistical significance was calculated using confidence intervals (CI). The Pearson Chi-square test was used to analyse the ignorance of this problem depending on the educational level extrapolated from the occupation of respondents. Results. 247 parents responded to the survey. 60.3% (95% CI 54.1- 66.2%) confirmed that nuts were included in birthday parties. 30.4% (95% CI 25-36.4%) confirmed that celebrations with nuts at their children’s nursery were made. 42.1% (95% CI 36.1-48.3%) believed that nuts were harmless for their young children. The age of administration of nuts was independent on the educational level extrapolated of parents (χ²=10.721, p = 0.295), although it did influence on the ignorance of the danger of nuts (41.2% (95% CI 30.3-53%) of respondents with occupations that required higher educational level compared to 55.4% (95% CI 42.4-67.6%) of those with occupation that required less educational level (χ²=14.678, p = 0.002)). Conclusions. Regardless of the occupation, there is widespread ignorance concerning the age of introduction of nuts in children’s diet. Given the incidence and severity of the risk of aspiration, more prevention programs are necessary, and Health Authorities should take side in public awareness of this problem

RESUMO

OBJECTIVE: To Present the benefits of free autologous fat grafts in different pathologies of children. MATERIAL AND METHODS: Retrospective study was performed on 18 patients who received a treatment with an autologous fat graft during the 2009-2012 period. The surgical technique consisted in removing fat from a donor region, processing the fat in order to purify it by centrifugation and grafting injection. The following variables were analysed: age, sex, pathology, complications of the technique, visual aspects results, subjective results (by rating satisfaction from 1-4 in examination room, and by telephone), donor sites and number of sessions. RESULTS: Eighteen patients were studied. Eleven patients had scars (2 were burn sequelae, 8 were side effects of a previous surgery and 1 was postraumatic), 2 patients had breast asymmetry, 1 patient had bilateral breast agenesis and 4 patients had facial asymmetries (Parry-Romberg syndrome in 2 cases, Treacher-Collins and monorhinia). There were no complications with the surgical technique except for fat resorption in 11 patients that needed a new reinjection. All patients with scar sequelae showed considerable improvement. The patients with breast pathology, experienced objective improvement, with practically full symmetry and natural aesthetics. Three to four patients affected by facial asymmetry, achieved good results in contour and symmetry. In order to obtain optimal results, 7 of the patients required just one session and the rest of patients, needed more sessions. The donor area was the abdominal region in 12 patients and the calf region in 6. Similar results were achieved regardless of the donor area. The assessment of patient satisfaction showed these results: very satisfied in 12 patients, satisfied 4 patients, scarcely satisfied 2 patienst and no one was not satisfied. CONCLUSIONS: This study suggests that the use of autologous fat grafts is feasible in the pathologies mentioned previously due to the technical simplicity, the good cosmetic results and the absence of complications in our series.

RESUMO

Objetivo. Presentar una nueva técnica utilizando el tubo de Kehr (TK) en las anastomosis intestinales complejas.material y métodos. Estudio retrospectivo descriptivo de 8 pacientes, intervenidos desde 2007 hasta 2011, con anastomosis intestinal tutorizada por un TK. 7 pacientes fueron operados por atresia intestinal (5 yeyunales, 1 ileal y 1 duodenal) y 1 caso por estenosis yeyunal asociada a gastrosquisis. 4 casos (50%) fueron pacientes que habían sido intervenidos previamente, y en los que existieron complicaciones con la primera cirugía. técnica quirúrgica: consiste en introducir un TK por el asa dilatada. Un extremo de la "T" del TK se deja, con una ligadura, proximal a la sutura y el otro distal a la misma, actuando como tutor transanastomó-tico. El cabo restante es abocado a la piel y utilizado para alimentación enteral. Las variables estudiadas fueron: inicio de alimentación enteral, tiempo de alimentación a través del TK, de recuperación del tránsito intestinal, tiempo hasta alimentación oral completa y complicaciones. Resultados. No se presentaron complicaciones derivadas de la técnica. La alimentación se inició a través del TK entre 2º-10º día (mediana: 4.5), con una duración de 4-33 días (mediana: 7). Iniciaron tránsito intestinal con deposiciones entre el 2º-7º día (mediana: 3,5). Los pacientes que habían sido intervenidos previamente presentaban signos de colestasis y sepsis, que se solucionaron tras la cirugía. El TK se mantuvo entre 11-51 días (mediana: 22), retirándose sin incidencias. Conclusiones. Este estudio preliminar sugiere que el uso de TK en anastomosis complejas presenta ventajas, como la alimentación enteral precoz y tutorización de la sutura previniendo su acodamiento. Este procedimiento no ha sido reportado en la literatura consultada (AU)


Objective. To present a new technique using the Kehr’s T tube (KT) in complex intestinal anastomoses. materials and methods. Restrospective descriptive analysis of 8 patients intervened from 2007 to 2011. We performed intestinal anastomoses guided by a KT in 7 patients with intestinal atresia (yeyunal n=5, ileal n=1, duodenal n=1), and in 1 patient with yeyunal stenosis associated with gastroschisis. 4 cases (50%) were reoperations because of complications after the first surgery. Surgical technique: the KT is introduced through the dilated proximal bowel. The proximal end of the "T" is tied and the distal one acts as a transanastomotic guide and feeding tube. The long end of the T is externalized through the skin and used for the administration of the enteral nutrition formula. Studied variables were: beginning of enteral feeding, feeding time through the KT, time of intestinal motility recovery, time to complete oral feeding and complications. Results. There were no complications derived from the technique. Feeding was started through the KT between day 2 and 10 (median: 4.5), with a period of 4 to 33 days (median: 7). Patients started intestinal transit between days 2 and 7 (median: 3.5). Reoperated patients showed cholestasis and/or sepsis signs, which were solved with surgery. The KT was left in place between 11-51 days (median: 22), with no complications during or after the removal. Conclusions. The results of this preliminary study suggests that the use of the KT in complex anastomoses as a transanastomotic guide and feeding tube presents advantages, such as early enteral feeding and prevention of leakage and kinking of the intestinal suture. There were no complications derived from the procedure.As far as we know, this technique has not been previously reported in the literature (AU)
