RESUMEN
OBJECTIVE: To compare the radiological and clinical outcomes of endoscopic treatment of primary VUR using polyacrylate-polyalcohol copolymer (PPC-Vantris®) or dextranomer-hyaluronic acid copolymer (Dx/HA-Deflux®). MATERIALS AND METHODS: From October 2014 to April 2017, patients with primary VUR grade III to V that needed endoscopic treatment (ET) were eligible for this randomized clinical trial. We excluded toilet-trained patients with lower urinary tract symptoms. Patients were randomized and allocated into two groups: PPC group and Dx/HA group. After endoscopic treatment a voiding cystourethrography (VCUG) was performed at 6 months; if VUR was still present a second ET was performed. Radiological success was considered if postoperative VUR grade was 0 and clinical success rate was considered if no more fUTI appeared during follow-up. RESULTS: Forty-six patients were eligible but 2 did not accept the trial. Forty-four patients with 73 refluxing ureters were included. PPC: 34 refluxing ureters; and Dx/HA: 39 refluxing ureters. Both groups were statistically homogeneous and comparable. Mean follow-up was 27.6 months. Radiological success rate (82.2%) and clinical success rate (92.3%) were similar in both groups (p > 0.05). The volume of bulking agent used in those successfully treated was greater in Dx/HA group (p < 0.05). Distal ureter was excise in all cases of ureteral reimplantation after PPC treatment; however, distal ureter was preserved in all ureters reimplanted after Dx/HA injection. CONCLUSION: PPC and Dx/HA had similar outcomes, but we must warn that ureteral reimplantation after endoscopic treatment with PPC is difficult because of the periureteral fibrosis.

OBJECTIVE: To analyze whether the application of laparoscopic surgery in the treatment of pyeloureteral junction obstruction (PUJO) has been beneficial for pediatric patients. MATERIALS AND METHODS: Medical records of all patients undergoing PUJO surgery from January 1997 to December 2017 were retrospectively reviewed. Patients with <6-month follow-up and patients undergoing video-assisted surgery were excluded. Open surgery was compared with laparoscopic surgery. The following data were collected: surgical approach, need for and type of urinary diversion, operating time, mean hospital stay, complications, and restenosis rate. Ultrasound and diuretic renogram parameters were also retrieved. RESULTS: 328 Anderson-Hynes pyeloplasties were analyzed, 142 of which had been performed laparoscopically. Overall success rate was 96.6%, and complication rate was 11.9%. No significant differences were noted between open and laparoscopic surgery. In 97.5% of surgeries, urine was diverted using an external nephroureteral catheter, a double J stent, or a Salle stent, with significant differences between open and laparoscopic surgery. Mean operating time was significantly longer in laparoscopic surgery. Mean hospital stay was significantly shorter in the laparoscopic surgery group. CONCLUSION: Surgical approach does not play a role in PUJO surgery success. Therefore, in our view, laparoscopic surgery should be the technique of choice in pediatric patients.
OBJETIVO: Analizar si la aplicación de la cirugía laparoscópica en el tratamiento de la estenosis pieloureteral (EPU) han sido beneficiosos para el paciente pediátrico. MATERIAL Y METODO: Hemos revisado de forma retrospectiva las historias clínicas de todos aquellos pacientes intervenidos de EPU desde enero 1997 hasta diciembre 2017. Se excluyeron las que tuvieron seguimiento menor a 6 meses, y las cirugías videoasistidas. Se han comparado la cirugía abierta con la cirugía laparoscópica. Se han recogido los siguientes datos: abordaje quirúrgico, necesidad y tipo de derivación urinaria, tiempo quirúrgico, estancia media, complicaciones, tasa de reestenosis. Los parámetros ecográficos y del renograma diurético también han sido recogidos. RESULTADOS: Se han analizado 328 pieloplastias, 142 se realizaron laparoscópicamente. La tasa de éxito global ha sido del 96,6%, existiendo un 11,9% de complicaciones; sin existir diferencias significativas entre la cirugía abierta y la laparoscópica. En el 97,5% de las cirugías, la orina se derivó mediante catéter nefroureteral externo, catéter doble J o catéter tipo Salle; existiendo diferencias entre cirugía abierta y laparoscópica. El tiempo quirúrgico medio fue significativamente superior en la cirugía laparoscópica. La estancia media fue menor en el grupo de cirugía laparoscópica de forma significativa. CONCLUSION: La vía de abordaje no es un factor que influya en el éxito de la cirugía de la EPU, por ello pensamos que la cirugía laparoscópica es la técnica de elección en pacientes pediátricos.

INTRODUCTION: Some guidelines recommend an early voiding cystourethrography (VCUG) after endoscopic treatment of vesicoureteral reflux (VUR), but there's no consensus if it's necessary a long-term follow-up in these patients. The aim of our study is analyze if it's necessary a delayed VCUG after initial successful treatment with Dx/HA. MATERIAL AND METHOD: We have reviewed all medical charts of patients that underwent Dx/HA treatment from 2006 to 2010. We have selected patients with initial successful treatment and more than 3 years of radiological and clinical follow-up. We have analyzed late clinical and radiological outcomes. RESULTS: One hundred and sixty children with 228 refluxing ureters underwent Dx/HA endoscopic treatment with a mean follow-up of 52.13 months. Early VCUG was performed in 215 ureters with an initial successful rate of 84.1%. The group of study was 94/215 ureters with more than 3 years of follow-up with a delayed VCUG. VUR was still resolved in 79,8% of the ureters. Clinical success rate was 91.7%. The incidence of febrile urinary tract infection in those patients with cured VUR and those with a relapsed VUR was 8 and 15%, respectively; but there were no significant differences. We have not found any variable related with relapsed VUR except those ureters that initially received 2 injections (P<.05). CONCLUSION: If our objective in the treatment of VUR is to reduce the incidence of febrile urinary tract infection it is not necessary to perform a delayed VCUG even though the long-term radiological outcomes is worse than clinical outcome.

OBJECTIVE: To determine the incidence of urinary tract infection in those patients that we have used an ureteral double-J stent as internal diversion after urological procedures. MATERIAL AND METHODS: We reviewed all the medical records of patients who had a ureteral double-J stent after a urological procedure from August 2007 to May 2013. We have analyzed the following data: age, gender, type of prophylaxis, incidence of urinary tract infection (UTI), days of internal diversion with double-J stent, surgical procedure, bacterial characteristics, bacterial sensibility to antibiotics and UTI treatment. RESULTS: We have used 73 double-J stents as ureteral internal diversion in 67 patients with a mean age of 44.73±57.23. Surgical procedures were 50 laparoscopic Anderson-Hynes pyeloplasties in 49 patients, and 20 high-pressure balloon dilatation of the ureterovesical junction to treat primary obstructive megaureter in 15 patients; and 3 patients with ureterovesical obstruction after endoscopic treatment of vesicoureteral reflux. Forty three stents showed a bacterial colonization in cultures. Pseudomona aeruginosa was present in 9 (20.9%) stents. Only in 12 stents, bacterial colonization was sensible to antibiotic prophylaxis. Stent colonization was higher in boys and younger patients. Four patients had a febrile UTI. Incidence of UTI in younger patients that underwent HBPD of UVJ is higher. CONCLUSION: Bacterial colonization is frequent in double-J stents but the incidence of UTI is low. Double-J colonization is higher in younger patients. Patients that underwent HPBD have a higher risk of UTI related with ureteral double J stent.

Dystrophic epidermolysis bullosa (DEB) is a rare inherited disorder characterized by blistering after minimal trauma. These blisters tend to form dystrophic scars, leading to limiting and life-threatening sequelae. The anaesthetic management of patients with DEB is a challenge, even for the most experienced anaesthesiologists, but basic principles can help us prepare the plan of care. The main goals are to prevent trauma/infection of skin/mucous, and to establish a secure airway without causing bullae. Patient positioning and the instruments used to monitor vital signs and administering anaesthetic agents can cause new lesions. It is advisable to lubricate the instruments and to avoid adhesive material and shearing forces on the skin. Besides the implications of the comorbidities, there is a potential difficult intubation and difficult vascular access. Acute airway obstruction can occur due to airway instrumentation. We report the case of a patient diagnosed with EBD difficult airway and undergoing correction of syndactylyl and dental extractions.

OBJECTIVE: To compare outcomes between high-pressure balloon dilatation of the ureterovesical junction (UVJ) and ureteral reimplantation with ureteral tapering to treat primary obstructive megaureter (POM). PATIENTS AND METHODS: Retrospective review of clinical data from patients who underwent surgical treatment of POM from 2005 to 2010. Patients were divided into two groups: endoscopic treatment (ET) with UVJ dilatation and ureteral reimplantation (UR) with Cohen's or Leadbetter-Politano neoureterocystostomy and Hendren's tapering. Preoperative studies included ultrasound scan (US), voiding cystourethrography, and diuretic isotopic renogram. Outcome parameters were US, differential renal function (DRF), presence of postoperative vesicoureteral reflux, need for secondary reimplantation and complications. RESULTS ET: 13 patients with a median age of 7 (4-24) months; UR: 12 patients with a median age of 14 (7-84) months, with no statistical differences in age and gender between groups. Preoperative US parameters were similar. ET: mean diameter of renal pelvis, calices and ureter was 23.5 mm, 13.46 mm and 15.77 mm respectively. UR: mean diameter of renal pelvis, calices and ureter was 22.25 mm, 11.75 mm, and 19.08 mm, respectively. Preoperative DRF was 45.62% and 39.33% for ET and UR, respectively (p > 0.05). Significant improvement of hydroureteronephrosis was observed in 11/13 patients of ET and 11/12 patients of UR (p > 0.05). Postoperative DRF was 42% and 48% for ET and UR, respectively (p > 0.05). Postoperative vesicoureteral reflux was observed in 2 patients of ET and 1 of UR (p > 0.05). Secondary ureteral reimplantation was needed in 3 patients of ET and 2 of UR (p > 0.05). CONCLUSION: Endoscopic treatment of POM is as effective as ureteral reimplantation but further randomized clinical trials are needed to support these results.

PURPOSE: To compare efficacy of Cohen's ureteral reimplantation and endoscopic treatment with Dx/HA in patients with primary VUR grades II, III and IV. METHODS: From April 2002 to June 2004, patients over 1 year old with VUR grade I, II, III or IV were included. Patients were randomized into two groups: endoscopic treatment (ET) or ureteral reimplantation (UR). In the ET group, an ultrasonography study was performed 24 h and 1 month after surgery, and two voiding cystourethrographies at 3 and 6 months post treatment. In the UR group, an ultrasonography study was done 7 days and 1 month after surgery and a micturial cystography 6 months post surgery. A postoperative nuclear direct cystogram was performed 5 years later in both groups. RESULTS: A total of 41 patients were included in this study: in ET 22 patients with 35 refluxing ureters and in UR 19 patients with 32 refluxing ureters. The VUR grades in ET were: 16 grade II, 16 grade III and 3 grade IV; and in UR: 15 grade II, 12 grade III and 5 grade IV. VUR was resolved in 91% (32/35) of ET (28% of ureters needed a second injection), and in 100% of UR group. Five years after the procedure, VUR was still resolved in 30/32 of ET and 32/32 of UR. CONCLUSION: Short- and long-term follow up shows that multiple endoscopic treatment of VUR grades II, III and IV with Dx/HA is as effective as ureteral reimplantation.

OBJECTIVE: To present our cases of ureteral obstruction after endoscopic treatment of vesicoureteral reflux (VUR) with dextranomer/hyaluronic acid (Dx/HA). PATIENTS AND METHODS: We collected data from patients who had suffered ureteral obstruction after endoscopic treatment of VUR with Dx/HA in our institution. RESULTS: From April 2002 to April 2011 we treated endoscopically 475 ureters with VUR, and detected 5 ureteral obstructions. Median age at reflux treatment was 39 months. Reflux grade before treatment was III in one patient and IV in four. Three ureterovesical junctions (UVJ) were blocked after a second endoscopic treatment. The median of Dx/HA injected was 1 ml (0.6-1.1). In two patients ureteral obstruction presented acutely and was treated with a ureteral stent. In the other three, the ureteral obstruction appeared gradually and was detected by ultrasound scans and MAG3 diuretic renogram; one underwent nephrectomy because of poor renal function, and the other two were treated with endoscopic dilatation of the UVJ. In all these patients both reflux and obstructions have resolved. CONCLUSIONS: On preoperative cystography, three of the patients had a narrowed distal ureter, and probably had a refluxing and obstructive megaureter. Other causes are not clear, except for those patients with acute presentation in whom edema of the UVJ was found. Ureteral obstruction after endoscopic treatment of VUR is rare. Endoscopic intervention such as ureteral stent placement or high-pressure balloon dilatation of the UVJ has good results as a treatment of acute and delayed obstruction.

Introducción: La mayoría de las guías recomiendan realizar una cistografía miccional (CUMS) temprana tras el tratamiento endoscópico del reflujo vesicoureteral (RVU), pero no hay consenso sobre cómo hacer el seguimiento a largo plazo en este grupo de pacientes. El objetivo de este estudio es analizar si es necesaria la realización de una CUMS tardía en aquellos pacientes tratados con éxito. Material y método: Hemos revisado las historias clínicas de aquellos pacientes tratados de RVU con el copolímero de dextranómero/ácido hialurónico (Dx/AH) desde 2006 a 2010. Se han seleccionado aquellos pacientes que estaban curados tras el tratamiento con más de 3 años de seguimiento y control cistográfico tardío. Hemos analizado los hallazgos clínicos y radiológicos a largo plazo. Resultados: Ciento sesenta niños con 228 uréteres refluyentes recibieron tratamiento con Dx/AH con un seguimiento medio de 52,13 meses. A 215 se les realizó CUMS de forma temprana, siendo la tasa de éxito del 84,1%. El grupo de estudio fueron 94/215 uréteres refluyentes que tuvieron un seguimiento clínico y cistográfico tardío mayor de 3 años. En el 79,8% la CUMS mostró ausencia de RVU, siendo la tasa de éxito tardío clínico del 91,7%. La incidencia de infección del tracto urinario febril entre aquellos que estaban curados desde el punto de vista radiológico frente a aquellos en los que recidivó el RVU fue del 8 y 15%, respectivamente. Solo existieron diferencias significativas en la recidiva del RVU entre aquellos uréteres que se habían tratado de forma inicial con una punción o con 2 punciones de Dx/AH. Conclusión: Si el objetivo del tratamiento del RVU es disminuir las infecciones del tracto urinario febril, no es necesario realizar una CUMS tardía tras un tratamiento exitoso inicial con Dx/AH, a pesar de que la tasa de éxito radiológico es menor que la del clínico

Objetivo: Determinar la incidencia de infección del tracto urinario en los pacientes en los que hemos utilizado un catéter ureteral doble J como desvío interno después de procedimientos urológicos. Material y métodos: Se revisaron todas las historias clínicas de los pacientes que tenían un catéter ureteral doble J después de un procedimiento urológico desde agosto de 2007 hasta mayo de 2013. Hemos analizado los siguientes datos: edad, sexo, tipo de profilaxis, incidencia de la infección del tracto urinario (ITU), días de desviación interna con catéter doble J, procedimiento quirúrgico, características bacterianas, sensibilidad de las bacterias a los antibióticos y tratamiento de ITU. Resultados: Hemos utilizado 73 catéteres doble J como desvío interno ureteral en 67 pacientes con una edad media de 44,73 ± 57,23. Los procedimientos quirúrgicos fueron 50 pieloplastias laparoscópicas Anderson-Hynes en 49 pacientes y 20 dilataciones con balón de alta presión de la unión ureterovesical para tratar megauréter obstructivo primario en 15 pacientes, y 3 pacientes con obstrucción ureterovesical después del tratamiento endoscópico del reflujo vesicoureteral. Cuarenta y tres catéteres mostraron una colonización bacteriana en los cultivos. Pseudomona aeruginosa estaba presente en 9 (20,9%) catéteres. Solo en 12 catéteres la colonización bacteriana era sensible a la profilaxis antibiótica. La colonización del catéter era mayor en los niños y los pacientes más jóvenes. Cuatro pacientes tuvieron una ITU febril. La incidencia de ITU en los pacientes más jóvenes que se sometieron a DBAP de UUV es mayor. Conclusión: La colonización bacteriana es frecuente en los catéteres doble J, pero la incidencia de ITU es baja. La colonización doble J es mayor en los pacientes más jóvenes. Los pacientes que se sometieron a DBAP tienen un mayor riesgo de ITU relacionada con el catéter ureteral doble J
Objective: To determine the incidence of urinary tract infection in those patients that we have used an ureteral double-J stent as internal diversion after urological procedures. Material and methods: We reviewed all the medical records of patients who had a ureteral double-J stent after a urological procedure from August 2007 to May 2013. We have analyzed the following data: age, gender, type of prophylaxis, incidence of urinary tract infection (UTI), days of internal diversion with double-J stent, surgical procedure, bacterial characteristics, bacterial sensibility to antibiotics and UTI treatment. Results: We have used 73 double-J stents as ureteral internal diversion in 67 patients with a mean age of 44.73 ± 57.23. Surgical procedures were 50 laparoscopic Anderson-Hynes pyeloplasties in 49 patients, and 20 high-pressure balloon dilatation of the ureterovesical junction to treat primary obstructive megaureter in 15 patients; and 3 patients with ureterovesical obstruction after endoscopic treatment of vesicoureteral reflux. Forty three stents showed a bacterial colonization in cultures. Pseudomona aeruginosa was present in 9 (20.9%) stents. Only in 12 stents, bacterial colonization was sensible to antibiotic prophylaxis. Stent colonization was higher in boys and younger patients. Four patients had a febrile UTI. Incidence of UTI in younger patients that underwent HBPD of UVJ is higher. Conclusion: Bacterial colonization is frequent in double-J stents but the incidence of UTI is low. Double-J colonization is higher in younger patients. Patients that underwent HPBD have a higher risk of UTI related with ureteral double J stent

La epidermólisis ampollosa distrófica (EAD) es una patología hereditaria infrecuente, caracterizada por la formación de ampollas ante mínimos traumatismos, que tienden a formar cicatrices distróficas y llevan a secuelas limitantes y amenazantes para la vida. Es frecuente que los pacientes afectados de EAD precisen diferentes intervenciones quirúrgicas a lo largo de su vida. Los principales objetivos del manejo anestésico son la prevención del traumatismo/infección sobre la piel o las mucosas y el establecimiento de una vía aérea segura sin producir ampollas. El posicionamiento del paciente y el material utilizado para la monitorización de signos vitales y para la administración de agentes anestésicos pueden producir nuevas lesiones. Debe lubricarse todo el material y evitar adhesivos y movimientos de fricción sobre la piel. Estos pacientes suelen presentar múltiples comorbilidades y accesos vasculares y vía aérea difíciles. La formación de nuevas ampollas durante la instrumentación de vía aérea puede llevar a una obstrucción aguda de la misma. Presentamos el caso de un paciente con EAD y vía aérea difícil sometido a corrección de sindactilia y exodoncia múltiple (AU)
