[Is there a difference in the postoperative follow up of ureteropelvic junction obstruction according to age?] / ¿Existe diferencia en la evolución postoperatoria de la estenosis pieloureteral según la edad?

OBJECTIVE: To compare postoperative follow up in patients older and younger than 12 months who underwent surgical treatment of ureteropelvic junction obstruction (UJO). MATERIAL AND METHODS: Retrospective study of 77 patients, 78 kidney units, intervened from UJO (2007-2014). We analyzed epidemiological, clinical, echographic, and pre and postoperative renogram variables, outcomes and complications. We divided the patients into 2 groups according to age: group A ≤ 12 months and group B > 12 months, comparing the results by statistical analysis, considering p < 0.05 statistically significant. RESULTS: Group A: 38 patients, 26 males (68.4%), one bilateral UJO and 22 rights (57.9%), 36 prenatal diagnoses (92.3%) and mean age of intervention 5.28 months [range 0.24 -11,28]. We performed 9 minilumbotomies, 29 assisted by retroperitoneoscopy (ARP) and 1 pneumatic dilation (PD). Group B: 39 patients, 26 males (66.7%), 10 rights (25.64%), 19 prenatal diagnoses (48.7%) and mean age 6.13 years [range 1.13-14.52]. 15 minilumbotomies, 20 ARP, 3 laparoscopic and 1 PD. Preoperative mean renal function (MRF) of group A: 35.9 ± 13.4 [range 8-57] vs. 39.74 ± 13.91 [range 9-57] in group B (p = 0.347). Postoperative MRF 43.29 ± 18.2 [range 12-100] group A and 39.41 ± 12.89 [range 11-54] group B (p = 0.464). Group A and B: 11 and 8 complications, respectively (p = 0.429). We did not find statistically significant differences in the mean preoperative anteroposterior diameter (DAP) between both groups (p = 0.313). We compared DAP at 3, 6, 12, 24 and 48 postoperative months, observing a greater reduction of DAP from group A compared to B; however, we found only statistically significant differences in DAP at 3 months postoperatively (p = 0.047). CONCLUSION: Renal DAP is reduced postoperatively more in patients younger than 1 year. Moreover, an improvement of the DRF after pieloplasty can be observed despite not being statistically significant.

OBJETIVO: Comparar la evolución postquirúrgica en pacientes mayores y menores de 12 meses intervenidos de estenosis pieloureteral (EPU). MATERIAL Y METODOS: Estudio retrospectivo de 77 pacientes, 78 unidades renales, intervenidos por EPU (2007-2014). Analizamos variables epidemiológicas, clínicas, ecográficas y de renogramas pre y postoperatorios, resultados y complicaciones. Dividimos a los pacientes en 2 grupos según la edad: grupo A ≤ 12 meses y grupo B > 12 meses, comparando los resultados mediante análisis estadísticos (p < 0,05 estadísticamente significativo). RESULTADOS: Grupo A: 38 pacientes, 26 varones (68,4%), una EPU bilateral y 22 derechas (57,9%), 36 diagnósticos prenatales (92,3%) y edad media de intervención 5,28 meses [rango 0,24-11,28]. Realizamos 9 minilumbotomías, 29 asistidas por retroperitoneoscopia (ARP) y una dilatación neumática (DN). Grupo B: 39 pacientes, 26 varones (66,7%), 10 derechas (25,64%), 19 diagnósticos prenatales (48,7%) y edad media 6,13 años [rango 1,13-14,52]. Realizamos 15 minilumbotomías, 20 ARP, 3 laparoscópicas y 1 DN. Función renal diferencial media (FRDM) preoperatoria del grupo A: 35,9 ± 13,4 [rango 8-57] vs. 39,74 ± 13,91 [rango 9-57] grupo B (p = 0,347). FRDM postoperatoria 43,29 ± 18,2 [rango 12-100] grupo A y 39,41 ± 12,89 [rango 11-54] grupo B (p = 0,464). Grupos A y B: 11 y 8 complicaciones, respectivamente (p = 0,429). No encontramos diferencias estadísticamente significativas en la media del diámetro anteroposterior (DAP) de la pelvis preoperatoria entre ambos grupos (p = 0,313). Comparamos los DAP a los 3, 6, 12, 24 y 48 meses postoperatorios, observando una reducción mayor del DAP del grupo A frente al B, sin embargo, solo encontramos diferencias estadísticamente significativas en el DAP a los 3 meses postoperatorios (p = 0,047). CONCLUSION: El DAP de la pelvis renal se reduce más en los pacientes menores de 1 año a los 3 meses postoperatorios. Además, podemos observar una evidente mejoría de la FRDM tras la pieloplastia a pesar de no encontrar diferencias estadísticamente significativas.

[The diagnosis of pilomatrixoma in children is not as easy as it may seem. A review of 126 cases]. / El diagnóstico del pilomatrixoma infantil no es tan fácil como parece: revisión de 126 casos.

OBJECTIVE: To describe our experience with pilomatrixomas, clinical presentation, clinical accuracy, associated diseases, and surgical treatment. METHODS: A retrospective review of patients with a pathology report of an excised pilomatrixoma between 2011 and 2014. Data regarding gender, age of intervention, number of masses, size, location, and preoperative clinical diagnosis, pathology report, recurrences, and associated diseases were collected. Statistical analysis was performed using EPIinfo 7.1.5. RESULTS: A total of 151 tumors in 138 patients were removed, 25 were excluded for having a clinical diagnosis of pilomatrixoma without confirmation of the pathology report. The remaining 126 cases have an average age of 8.26 years (range 1-14 years) and 50.72% are males. The tumors were located above the umbilicus in 97% of the cases, with a higher concentration of 50.72% in the head and neck. The clinical diagnosis corresponds with the pathology report in 69.05% of cases. Out of these confirmed cases the most frequent differential diagnosis is cystic lesion (11.90%) and dermoid cyst (10.22%). There were no cases of malignant degeneration. The average diameter is 1.13 cm, there were no recurrences, but there were 11 cases of a new lesion in a different location. There is no statistical association with other pathologies. The most frequent diseases found were obesity (3.62%) and attention deficit syndrome (3.62%). CONCLUSION: The pilomatrixoma is a tumor that appears predominantly in the head and neck, and has a difficult clinical diagnosis. Complete removal is curative, although it does not prevent the appearance of new lesions.

OBJETIVO: Describir nuestra experiencia con pilomatrixomas, examinando la presentación clínica, acierto clínico, enfermedades asociadas y tratamiento quirúrgico. MATERIAL Y METODOS: Estudio retrospectivo de los pacientes con diagnóstico anatomo-patológico (AP) de pilomatrixoma, en el periodo de 2011 a 2014. Se recopilaron datos sobre genero, edad de intervención, número de tumoraciones, tamaño, localización, diagnóstico preoperatorio, anatomía patológica, reintervenciones y patología asociada. Se realizó el análisis estadístico con EPIinfo 7.1.5. RESULTADOS: Se extirparon un total de 151 tumores en 138 pacientes, excluyendo 25 tumoraciones por tener diagnóstico clínico de pilomatrixoma sin confirmación patológica. Los 126 casos que tienen confirmación AP de pilomatrixoma tienen una edad media de exéresis de 8,26 años de edad (1-14 años) y el 50,72% son del género masculino. El 97% de los tumores se localizan por encima del ombligo, concentrándose en la cabeza y cuello el 52,9%. La sospecha clínica corresponde con AP en el 69,05%. De los casos confirmados, los diagnósticos clínicos diferenciales más frecuentes son lesión quística (11,90%) y quiste dermoide (10,22%); no hubo pilomatrixomas con degeneración maligna. La media de diámetro es de 1,13 cm, no hubo recidivas locales, pero sí 11 nuevos casos de pilomatrixomas en otra localización. No hay asociación estadísticamente significativa a otras patologías. Las enfermedades más frecuentes encontradas son la obesidad (3,62%) y el síndrome de déficit de atención (3,62%). CONCLUSION: El pilomatrixoma es una tumoración predominantemente de aparición en cara y cuello, de difícil diagnóstico clínico. La exéresis completa es curativa, aunque no previene la aparición de nuevas lesiones.

[Efficacy of the retroperitoneal-assisted laparoscopic pyeloplasty versus the mini posterior lumbotomy approach]. / Eficacia de la pieloplastia asistida por retroperitoneoscopia versus a la realizada por minilumbotomía posterior.

OBJECTIVE: To evaluate the results of the retroperitoneal-assisted laparoscopic pyeloplasty (RALP) versus the mini posterior lumbotomy pyeloplasty (MPLP). MATERIAL AND METHODS: A retrospective study of 77 patients diagnosed with ureteropelvic junction obstruction between 2007 and 2013 was made, analyzing the surgical technique, complications and results. The anteroposterior pelvic diameter of the kidney, the thickness of the renal parenchyma, the renal function and the morphology of the renogram curve were also evaluated and compared. RESULTS: We performed 50 RALP and 21 MPLP. Median age of intervention: 10.85 moths (ICR 86.8) in RALP and 23.30 moths (ICR 54.7) in MPLP. No significant differences were found in surgical time (p>0.05). Double J was left in 90% of the RALP and 52.4% of the MPLP. Median length of incision was 1.5 cm of the RALP and 3.0cm in MPLP(p<0.05). The Median hospital stay was 2.0 days and 3.0 respectively (p<0.05). We found surgical complications (restenosis and urinoma) in 9 patients of the RALP group and 1 in the mini lumbotomy group (p>0,05). The follow-up was performed using ultrasound in an average of 68,04 months of age (range 7.5-186.5) and diuretic renogram in an average of 50,25 months of age (range 6,6-173,8). The above parameters showed improvements in both groups of patients without significant differences. CONCLUSIONS: In our experience, the RALP is a technique with a greater rate of complications than the expected. Moreover, the MPLP, is a technique we consider safe and with adequate aesthetic and functional results.

OBJETIVO: Evaluar la pieloplastia asistida por retroperitoneoscopia, exteriorizando la unión pieloureteral (PAR) versus la pieloplastia por minilumbotomía posterior en ángulo costovertebral (PMLP). MATERIAL Y METODOS: Estudio retrospectivo de 77 pacientes diagnosticados de estenosis pieloureteral (2007-2013), se analizaron técnica, complicaciones y resultados, mediante la valoración del diámetro anteroposterior de la pelvis renal, grosor del parénquima renal, función renal y morfología de la curva del renograma. RESULTADOS: Realizamos 50 PAR y 21 PMLP. Edad mediana de intervención: 10,85 meses [rango intercuartílico (IC) 86,8] en PAR y 23,3 meses (rango IC 54,7) en PMLP. No hubo diferencias significativas en tiempo quirúrgico. Se dejó doble J en 90% de las PAR y en 52,4% de las PMLP. La incisión fue 1,5 cm en la PAR y 3,0 cm de mediana (rango IC 1,0) en la PMLP (p<0,05). La mediana de estancia fue 2,0 días y 3,0 respectivamente (p<0,05). Encontramos complicaciones (reestenosis y urinomas) en 9 pacientes del grupo PAR y en uno en el grupo de minilumbotomía (p>0,05). El seguimiento mediante ecografía en una media de 68,04 meses de edad (rango 7,5-186,5) y renograma diurético en una media de 50,25 meses de edad (rango 6,6-173,8), evidenciaron mejora en los parámetros arriba señalados en ambos grupos de pacientes, sin diferencias significativas. CONCLUSIONES: En nuestra serie, la PAR es un abordaje con un índice de complicaciones mayor al esperado. Por otra parte, la PMLP es un abordaje seguro y con resultados estéticos y funcionales adecuados.

[Endocrine disrupting chemicals exposure and other parental factors in hypospadias and cryptorchidism etiology]. / Exposición a disruptores endocrinos y otros factores paternos en la etiología del hipospadias y la criptorquidia.

AIM OF THE STUDY: To investigate the association between endocrine disrupting chemicals (EDC) exposure and other paternal factors in the etiology of hipospadias and cryptorchidism. METHODS: A case-control study. Cases were infants between 0 and 6 years of age diagnosed with hypospadias or cryptorchidism in our pediatric urology and general pediatric surgery services during a period of 6 months, and controls were infants with the same range of age attending the same services without any urological problem. Several variables were collected by face-to-face interviews with both parents. After data abstraction, we compared the characteristics of both groups using parametric statistical tests. MAIN RESULTS: A total of 180 patients were studied, 90 cases (45 hypospadias/45 cryptorchidism) and 90 controls with a mean age of 2,37 ± 1.50 years [range 0,5-6]. Median of mother´s age was significantly greater in case group (34,40 ± 5,64 versus 31,74 ± 5,05; p= 0,001). Significant differences were observed between cases and controls in regard to maternal occupational exposure to EDC (mainly phthalates), adjusted Odds ratio (OR) was 3.67 [95% confidence interval (CI): 1.28-10.51; p= 0,018] and regarding the paternal occupational exposure to EDC (mainly pesticides and herbicides), adjusted OR was 6.65 [95% CI: 2.60-17.02; p= 0,001]. Increased risk was also observed in smoking fathers and fathers who drink alcohol, adjusted Odds ratio were 2.36 [95% CI: 1.11. CONCLUSIONS: This study represents a little contribution to the possible etiologic factors of hypospadias and cryptorchidism, further studies with higher statistical power would be needed to prove it.

OBJETIVOS: Investigar la asociación entre la exposición a disruptores endocrinos (DE) y otros factores en el desarrollo del hipospadias y la criptorquidia. MATERIAL Y METODS: Estudio de casos y controles. Consideramos como casos a los niños de entre 6 meses y 6 años de edad diagnosticados de hipospadias y/o criptorquidia que acudieron a las consultas de Urología/Cirugía durante un período de estudio de 6 meses y como controles, a los niños con mismo rango de edad que acudieron a las mismas consultas con otros diagnósticos. Recogimos las variables de interés mediante una encuesta epidemiológica y comparamos los resultados obtenidos en cada grupo mediante tests estadísticos paramétricos. RESULTADOS: Estudiamos 180 pacientes, 90 casos (45 hipospadias/45 criptorquidias) y 90 controles, con edad media de 2,60 ± 1,72 años [rango 0,5-6]. Las medias de edad gestacional y peso al nacer fueron menores en el grupo-caso sin objetivarse diferencias significativas. La edad media materna fue significativamente mayor en el grupo-caso (34,40 ± 5,64 versus 31,74 ± 5,05; p= 0,001). Encontramos asociación significativa entre la exposición ocupacional materna a DE (ftalatos principalmente) y el grupo-caso siendo la Odds ratio (OR) de 3,67 (IC 95%: 1,28-10,51; p= 0,018) y también en la paterna (principalmente a pesticidas/herbicidas) con OR= 6,65 (IC 95%: 2,60-17,02; p= 0,001). Encontramos asociación significativa entre el consumo de tabaco y alcohol paternos y el grupo-caso: OR= 2,08 (IC 95%: 1,11-3,87; p= 0,029) y OR= 2,50 (IC 95%: 1,36-4,57; p= 0,003) respectivamente. CONCLUSIONES: Este estudio supone una pequeña aportación respecto a los posibles factores etiológicos del hipospadias y la criptorquidia, y demuestra la necesidad de estudios ulteriores con mayor potencia estadística para aumentar la evidencia científica de nuestros hallazgos.

Nuestra experiencia con el uso de alfa-líticos en el tratamiento de la disfunción de vaciado / Our experience with the use of alpha-lithic therapy in the treatment of voiding dysfunction

Introducción. El vaciamiento disfuncional (VD) se debe a una disfunción en la musculatura del suelo pélvico, ocasionado por una hiperactividad del esfínter uretral y de la musculatura de esa zona durante la fase de vaciado del ciclo miccional. Los tratamientos utilizados son recomendar hábitos miccionales correctos, biofeedback y ejercicios de relajación pélvica. En la actualidad, también se utilizan fármacos, como alfalíticos e injección de toxina botulínica, pero su experiencia en niños es escasa. Objetivos.

INTRODUCTION: Dysfunctional voiding (DV) is due to a dysfunction in the pelvis floor muscles caused by hyperactivity of the urethral sphincter and the musculature of this zone during the voiding phase of the micturition cycle. The treatments used are recommending correct micturition habits, biofeedback and pelvic relaxation exercises. Currently, drugs are also used, such as alpha lithic drugs and injection of botulinic toxin, however its experience in children is limited. OBJECTIVES: Show our experience with the use of alpha-lithics in patients with DV. MATERIAL AND METHODS: Review of patients with DV treated with alpha-lithics in our institution. RESULTS: 6 patients with DV were treated with alpha-lithics (Alfuzosin or Doxazosin). Girl (12 years) with Wolfram Syndrome with significant post-void residual urine, who initially rejected intermittent catéter. Residual urine decreases slightly with treatment, but isn't enough. Boy (7 years) with uretral duplicity and difficulty urine flow without observable stenosis. He had initial improvement but then required continent bladder diversión and vasectomy due to recurrent orchiepididymitis. Boy (5 years) with ureteral-bladder stenosis and ureteral reimplantation with urinary tract infection and vesico-ureteral reflux that did not improve (an anatomic obstruction was subsequently found). Boy (12 years) with tethered cord and pyelonephritis, who rejected intermittent catheter. He hadn't improvement and he required continent bladder diversión. Boy (7 years) with Syringomyelia, operated in another center for vesico-ureteral reflux with ureteral reimplantation, with recurrent urine infections, who hadn't improvement and required continent bladder diversion. Boy (10 years) with resected urethra valves and normal cystoscopy, with episodes of urine retention, without improvement with treatment. CONCLUSION: The role of alpha-lithics in the treatment of dysfunctional voiding in children is limited and of doubtful efficacy. It may be useful in patients with significant post-micturition residue.

[A new clinical evaluation scale for incontinence: its use in anorectal atresias]. / Neuva escala de valoracion clinica de la incontinencia: su aplicacion en las atresias anorrectales.

We present a clinical scoring system to obtain a quantitative and accurate assessment of anorectal incontinence. We evaluate ten components, each of one is pointed between 0 and two, then overall incontinence punctuation (I.P.) is between 0 and 20. Variables define clinical data relative to patient's intestinal habits and hygienic methods, voluntary control degree of defecation and repercussion of patient's incontinence in social and physical capabilities. Punctuation lower than nine concerns to a poor continence; It is fair between nine and 14 points and 15 or higher punctuation indicates a good continence mechanism. This incontinence punctuation method (I.P.) has been applied to 23 patients, aged between two and 17 years, operated because high imperforate anus by PSARP procedure in 15 cases and by abdomino-perineal pull-through according to Romualdi-Soave technique in eight cases. We found statistic significative difference between the group of patients aged less than 5 years and the group aged between 5 and 10 years. There is not statistic significative differences between the two procedures used in surgical treatment, although I.P. is slightly higher in cases operated by PSARP procedure than in cases treated with Romualdi-Soave technique, when we compare the two groups with similar mean age.

[Analysis of mortality in myelomeningocele]. / Análisis de la mortalidad en el mielomeningocele.

Authors present a study of 84 patients with myelomeningocele between years 1971 to 1985. They analyze morbimortality related to level and condition of the lesion, Lorber's selection criteria and treatment received. They find better survival in females and in patients in whom surgical closure of the lesion was carried out without variations if one Lorber's criteria is present. The moment of operation did not change survival and was not related with development of hydrocephaly.

[Ingestion of batteries: treatment with water overload. Review of 175 cases]. / Ingestión de pilas: tratamiento por sobrecarga hídrica. Revisión de 175 casos.

The authors have treated 6 cases of childhood ingestion of disk batteries with bowel irrigation by nasogastric sonde. The disk was expeled with faeces in less than 12 hours without complications. The world literature (169 cases) on this subject is reviewed.

[Intestinal invagination: 12 years of experience]. / Invaginación intestinal: doce años de experiencia.

One hundred and forty two cases of intussusception were treated in our hospital since 1970 to 1982. Patients were divided for analysis into two groups, each consisting of 71 consecutively treated patients. In the second group (1977-1982) the hydrostatic pressure reduction was attempted under general anaesthesia an was successful in 50% of the patients. We compare both groups from the point of view of hydrostatic pressure reduction and conclude that anaesthesia significantly reduces the number of surgical procedures in children with intussusception.
