[Urethroplasty with lateral pedunculated flap for complicated hypospadias]. / Uretroplastia con colgajo lateral pediculado para las hipospadias complicadas.

UNLABELLED: With the modern techniques, we can resolve almost the totallity of hypospadias. But there are patients with recurrent fistulas associated to uretral stenosis that can finish all the surgical possibilities. MATERIAL AND METHODS: Retrospective review. Lateral based flap uretroplasty consists in the exposition of the uretra, to reconstruct in one-stage the original neourethra with the lateral skin of the penis. RESULTS: From 2008, we have correct 5 patients with a mean age of 12,1 years (9-15) and a weight of 55,34 kg (22-98 kg). All of them were previously corrected 3 to 7 times, with recurrent fistulas. At the office, stenosis urethral was verified. Surgical correction was made in 90-110 minutes and results were positive in all patients, correcting the stenosis after a follow-up of more than a year. Only the oldest two patients had present minimally glans fistula. CONCLUSIONS: Lateral based flap urethroplasty is a useful technique for the correction of the complicated fistulas, allowing the correction of the fistulas and the stenosis of the urethra.

Uretroplastia con colgajo lateral pediculado para las hipospadias complicadas / Urethroplasty with lateral pedunculated flap for complicated hypospadias

Las técnicas habituales de los hipospadias permiten resolver la práctica totalidad de esta patología con resultados muy positivos. Desgraciadamente, existen pacientes que se fistulizan repetidas veces, agotando las posibilidades quirúrgicas. Generalmente se asocian a estenosis uretral. Queremos presentar una técnica que nos ha facilitado la reparación de estos pacientes con resultados esperanzadores . Material y métodos. Revisión retrospectiva de una serie de casos. La técnica del colgajo lateral pediculado consiste en un desmontaje dela uretra y exposición de la misma, para proceder a su reconstrucción en un solo tiempo por medio de la piel lateral de la uretra que se tubulariza sobre la neouretra primitiva. Resultados. Desde 2008 hemos intervenido 5 pacientes con una edad media de 12,1 años (9-15) y un peso de 55,34 kg (22-98 kg).Previamente habían sufrido de 3 a 7 operaciones de corrección de hipospadias, siempre fistulizadas. En consulta se comprobó la estenosis uretral en todos los pacientes. La intervención se realizó en un tiempo de 90-110 minutos y los resultados fueron favorables en todos los pacientes, resolviéndose las estenosis, con un seguimiento medio superior al año. Tan solo los dos pacientes más mayores han presentado mínimas fístulas glanulares. Conclusiones. La uretroplastia con colgajo lateral pediculado es una técnica útil para el tratamiento de los hipospadias complicados permitiendo la resolución de las fístulas y, especialmente, de las estenosis de uretra (AU)

[Chromophobe renal cell carcinoma, an exceptional entity in childhood: a case report]. / Carcinoma renal de células cromófobas, una entidad excepcional en la infancia: caso clínico.

Chromophobe renal cell carcinoma (CRCC) is a rare variant of renal carcinomas arising from the intercalated cells of the distal renal tubule and representing 5% among all renal tumors. Its biological behaviour is variable, less aggresive than clear cell renal carcinoma. Histochemical, ultrastructural and molecular genetic characteristics are different from other renal carcinomas. Age at presentation is about the 6th decade of life. We report an exceptional 10 year-old boy case with a CRCC. Diagnostic and therapeutic aspects for the management of this tumor are reviewed.

Carcinoma renal de células cromófobas, una entidad excepcional en la infancia: caso clínico / Chromophobe renal cell carcinoma, an exceptional entiy in childhood: a case report

El carcinoma renal de células cromófobas (CRCC) es una variante rara de carcinoma renal que se origina de las células intercaladas del epitelio tubular distal y constituye un 5% de los tumores renales. Es un tumor de comportamiento biológico variable, menos agresivo que el carcinoma convencional de células claras. Presenta características histoquímicas, ultra estructurales y genéticas diferentes al resto de carcinomas renales. La edad de presentación suele ser hacia la 6ª década de vida. Presentamos un caso excepcional de CRCC en un niño de 10 años de edad. Se revisan los aspectos diagnósticos y terapéuticos del manejo de este tumor (AU)

Hernias más frecuentes de la pared abdominal / The most common abdominal wall hernias

La patología más frecuente hoy en día en las unidades pediátricas de cirugía mayor ambulatoria son las hernias de la pared abdominal. Por ello pensamos que el objetivo principal de este trabajo era dar a conocer a pediatras y médicos de familia los datos clínicos, el tratamiento quirúrgico y el circuito asistencial de esta entidad eminentemente quirúrgica. Incluimos la hernia inguinal indirecta, la hernia umbilical, la hernia epigástrica, la hernia crural y, por último, la hernia ventral lateral o de Spiegel. Los puntos de controversia en cada una de las patologías, como son la revisión del lado contralateral en la hernia inguinal indirecta o el caso especial de los pacientes prematuros por la mayor probabilidad de apneas postoperatorias, son fruto, además de una extensa revisión bibliográfica, de la experiencia de un centro especializado de tercer nivel durante 35 años

Currently, abdominal wall hernias are the conditions most frequently treated in a pediatric ambulatory surgery unit. For this reason, in this paper, we proposed to provide a detailed report of the clinical data, surgical management and the treatment protocol associated with this surgical entity for pediatricians and general practitioners. We include indirect inguinal hernia, umbilical hernia, ventral hernia, femoral hernia and, finally, Spiegelian hernia. The surgical exploration of the contralateral side in inguinal hernia and the special case of premature infants, because of the increased probability of postoperative apneas, seem to be the major points of controversy with respect to these entities. We have reviewed the literature extensively and the experience of our hospital over the last 35 years

[Ovarian torsion in early childhood]. / Torsión de ovario en la edad infantil.

Three cases of torsion of normal the uterine adnexa in premenarcheal girls are reported. The possible etiopathogenic mechanisms are commented, and the operative management is discussed. The value of ultrasonography in early diagnosis is pointed out.
