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

UNLABELLED: Invasive imaging methods that require catheterization are used for the diagnosis of vesicoureteral reflux. Our aim is to assess the usefulness of interleukin urinary levels for the diagnosis of reflux in children without urinary tract infection. METHODS: Case-control study in children who underwent a voiding cystourethrogram: forty cases diagnosed of reflux and 80 controls. Concentrations of IL-1beta, IL-6 and IL-8 related to creatinine levels (pg/micromol) were determined in urine samples in all. RESULTS: Sixty-two patients were males and fifty-eight females, with a mean age of 2.4 years. Indications for cystography were previous urinary tract infection in 78 cases (65%), prenatal diagnosis in 24 cases (20%) and postnatal diagnosis of uropathy or family history in 18 cases (15.1%). No significant differences were observed between cases and controls in IL-1beta/creatinine and IL-6/creatinine levels. However, IL-8/creatinine levels were almost significant higher in case group (median 3.5 pg/micromol; SD 9.2) than in control group (median 1.54 pg/micromol; SD 3) (P=0.001). The odds ratio was 5.57 (CI95%: 1.51 a 20.60) (X(MH)=2.80; p=0.005). CONCLUSIONS: Urinary levels of IL-8/creatinine are elevated in children with vesicoureteral reflux, even in absence of urinary tract infection. It could be used as a non-invasive marker for detection of subclinical cases of disease.

RESUMO

En el diagnóstico del reflujo vésico-ureteral se emplean métodos de imagen invasivos que requieren sondajes. Nuestro objetivo es evaluarla utilidad de los niveles urinarios de interleuquinas en el diagnóstico del reflujo en niños sin infección urinaria en curso. Métodos. Estudio de casos y controles en niños que acuden a realizar una cistouretrografía miccional (CUMS): 40 casos con reflujo y80 controles. Se determinó en todos la concentración en orina de IL-1,IL-6 e IL-8 en relación con la creatinina. Resultados. 62 niños y 58 niñas, con 2,4 años de edad media. La CUMS se indicó por infección urinaria previa en 78 (65%), hallazgos prenatales en 24 (20%) y diagnóstico postnatal de uropatía o historia familiar en 18 (15,1%). No se han observado diferencias significativas en los niveles urinarios de IL-1/creatinina e IL-6/creatinina entre ambos grupos; sin embargo, los niveles de IL-8/creatinina fueron significativamente más altos en los casos (media 3,5 pg/μmol; SD 9,2) que en los controles (media 1,54 pg/μmol; SD 3) (p=0,001). La odds ratio fue de5,57 (IC 95%: 1,51 a 20,60) (XMH=2,80; p=0,005).Conclusiones. Los niveles urinarios de IL-8/creatinina están elevados en niños con reflujo, incluso en ausencia de infección. Estos podrían utilizarse como biomarcador no invasivo para la detección de los casos subclínicos de enfermedad (AU)

RESUMO

El abordaje laparoscópico retroperitoneal está desplazando al transperitoneal y la cirugía abierta en un gran número de procesos renales benignos .En los últimos 6 años hemos realizado 20 retroperitoneoscopias,10 con abordaje lateral y 10 con posterior. Fueron 13 nefrectomías totales y 7 parciales en niños de 4,1 años de media. El tiempo medio quirúrgico fue 200 minutos en las totales y 278 en las parciales. La alimentación oral se reestableció a las 11,4 horas de media y la estancia hospitalaria postoperatoria fue de 1,58 días en las nefrectomías totales y de 2,18 enlas parciales. No hubo pérdidas hemáticas y las complicaciones fueron dos urinomas, dos patologías asociadas al muñón ureteral y una hematuria transitoria. No se encontraron diferencias significativas entre abordaje posterior y lateral en cuanto a estancia, inicio de alimentación o complicaciones, aunque el tiempo medio quirúrgico fue menor en el abordaje posterior (media 170 min; SD 17,3) que en el lateral (media 216 min; SD41) (P=0,024) para nefrectomías totales. La retroperitoneoscopia ofrece un acceso seguro reduciendo la morbilidad asociada al procedimiento transperitoneal. El abordaje posterior facilita el control vascular, mantiene el peritoneo más alejado y permite realizar el procedimiento con menor número de puertos, maximizando el espacio de trabajo (AU)


The retroperitoneal laparoscopic approach is displacing open surgery and transperitoneal approach for several benign renal conditions .In the past 6 years we have performed 20 procedures, 10 with lateral position and 10 with posterior prone one: 13 total nephrectomies and7 heminephrectomies in children aged 4,1 years on average. Mean operative time was 200 minutes in partial procedures and 278 in the totalones. Oral feeding was restored to 11,4 hours and average hospital postoperative stay was 1,58 days in total nephrectomies and 2,18 inheminephrectomies. There was no intraoperative bleeding. Complications were two urine leaks, two infections due to residual ureteral stumps and a case of transient hematuria. There were no significant differences between posterior and lateral approaches as to hospital stay, time of onset of oral feeding or complications, although the average operative time was shorter in the posterior approach (mean 170 min, SD 17,3) than in the lateral one (mean 216 min, SD 41) (P=0,024) in total nephrectomies. Retroperitoneoscopy allows a safe access to the kidney and avoids morbidity associated with the transperitoneal access. The posterior approach provides better vascular control, maintains the peritoneum far and allows the procedure with fewer ports, maximizing work space (AU)

RESUMO

La enterocolitis necrotizante (ECN) y la perforación intestinal aislada(PIA) son frecuentes en recién nacidos de muy bajo peso (RNMBP) y requieren cirugía el 20-40%. Hemos revisado retrospectivamente los RNMBP intervenidos por ECN y PIA entre el 2000 y el 2010, dividiendo la muestra en 3 grupos: 1) laparotomía inicial; 2) drenaje peritoneal temporal y laparotomía diferida; 3) drenaje peritoneal. De los 487 RNMBP ingresados en nuestro Hospital, 80 casos fueron ECN o PIA y de estos, el 31% (n= 25)fueron intervenidos quirúrgicamente. La edad gestacional media fue de 26 +3 semanas, 14 niñas y 11 niños, peso medio de 801,4 g (rango: 460 a 1.490g). Tuvieron neumoperitoneo el 48% (n= 12). Realizamos laparotomía inicial en 12 casos, drenaje más laparotomía en 10 y drenaje en 3 pacientes. El promedio de horas entre el drenaje y la laparotomía fue de 69,6. El 68%eran ECN y el 32% PIA. La laparotomía inicial aportó mayor supervivencia(P= 0,001) y la mortalidad general fue del 32% (8 éxitus). El procedimiento quirúrgico óptimo debe basarse en las condiciones clínicas del paciente .Consideramos que la laparotomía inicial debería ser el tratamiento para los pacientes con perforación intestinal por ECN y PIA (AU)


Necrotizing enterocolitis (NEC) and isolated intestinal perforation(IP) are common diseases in very low birth weight infants (VLBW) and require surgery in 20-40% of cases. We have performed a retrospective ereview of VLBW infants with NEC or IP who underwent a surgical procedure between 2000 and 2010, either initial laparotomy (group 1),peritoneal drain placement and subsequent laparotomy (group 2) orperitoneal drainage (group 3). Of 487 VLBW infants admitted to our hospital in the last ten years, 80 patients had NEC or IP, out of these,31% (n= 25) were treated surgically. The study population consisted of 14 girls and 11 boys with a mean gestational age of 26+3 weeks and mean birth weight of 801.4 g (range460 to 1,490 g). Pneumoperitoneum was seen in 48% of cases (n= 12).Twelve patients underwent initial laparotomy, 10 patients were treated with peritoneal drainage and subsequent laparotomy and in 3 patient a peritoneal drainage was placed .Mean time between drainage and laparotomy was 69.6 hours Sixty eight percent of patients had NEC and thirty-two percent were IP. Survivalrate was higher in the group who underwent initial laparotomy(p= 0.001) with an overall mortality of 32% (8 deaths). Optimal surgical procedure must be decided upon clinical condition of individual patients.We consider that initial laparotomy should be the treatment option inVLBW infants with intestinal perforation due to NEC or IP (AU)

Oral feeding was restored to 11,4 hours and average hospital postoperative stay was 1,58 days in total nephrectomies and 2,18 in heminephrectomies. There was no intraoperative bleeding. Complications were two urine leaks, two infections due to residual ureteral stumps and a case of transient hematuria. There were no significant differences between posterior and lateral approaches as to hospital stay, time of onset of oral feeding or complications, although the average operative time was shorter in the posterior approach (mean 170 min, SD 17,3) than in the lateral one (mean 216 min, SD 41) (P=0,024) in total nephrectomies. Retroperitoneoscopy allows a safe access to the kidney and avoids morbidity associated with the transperitoneal access. The posterior approach provides better vascular control, maintains the peritoneum far and allows the procedure with fewer ports, maximizing work space.

RESUMO

Necrotizing enterocolitis (NEC) and isolated intestinal perforation (IP) are common diseases in very low birth weight infants (VLBW) and require surgery in 20-40% of cases. We have performed a retrospective review of VLBW infants with NEC or IP who underwent a surgical procedure between 2000 and 2010, either initial laparotomy (group 1), peritoneal drain placement and subsequent laparotomy (group 2) or peritoneal drainage (group 3). Of 487 VLBW infants admitted to our hospital in the last ten years, 80 patients had NEC or IP, out of these, 31% (n=25) were treated surgically. The study population consisted of 14 girls and 11 boys with a mean gestational age of 26+3 weeks and mean birth weight of 801.4 g (range 460 to 1490 g). Pneumoperitoneum was seen in 48% of cases (n=12). Twelve patients underwent initial laparotomy, 10 patients were treated with peritoneal drainage and subsequent laparotomy and in 3 patients a peritoneal drainage was placed. Mean time between drainage and laparotomy was 69.6 hours. Sixty-eight percent of patients had NEC and thirty-two percent were IP. Survival rate was higher in the group who underwent initial laparotomy (p = 0.001) with an overall mortality of 32% (8 deaths). Optimal surgical procedure must be decided upon clinical condition of individual patients. We consider that initial laparotomy should be the treatment option in VLBW infants with intestinal perforation due to NEC or IP.
