Colgajo de túnica vaginal en la prevención de fístulas postoperatorias tras reparación de hipospadias severos: ¿ha terminado la búsqueda del Santo Grial? / The tunica-vaginalis flap to prevent postoperative fistula following severe hypospadias repair: Has the search for Holy Grail ended?

Introducción: La fístula posterior a la reparación del hipospadias sigue siendo un desafío para el hipospadiólogo, por lo que se han desarrollado diversas técnicas. Sin embargo, la incidencia de la fístula postoperatoria se encuentra entre el 10 y el 30%, y aumenta de acuerdo con la severidad del hipospadias. Hemos realizado un estudio para evaluar la eficacia del colgajo de túnica vaginal en la prevención de la formación de fístulas tras la reparación de casos severos de hipospadias.Materiales y métodosSe realizó un estudio observacional en un centro terciario entre 2008 y 2017. El estudio incluyó a niños con hipospadias severos (proximal, penoescrotal, escrotal y perineal). En todos los pacientes se usó un colgajo de túnica vaginal para reforzar la uretroplastia. Todos los pacientes recibieron seguimiento durante al menos un año tras finalizar el tratamiento.ResultadosSe incluyó un total de 210 pacientes en el estudio. Se realizó reparación en 2 etapas de Bracka en 180 pacientes con hipospadias penoescrotal o un meato aún más proximal. Los 30 pacientes restantes con hipospadias proximales se sometieron a la reparación de Snodgrass de una sola etapa. Cuatro (2%) pacientes desarrollaron fístulas, todos después de la reparación en 2 etapas, y la mitad de ellos requirieron corrección quirúrgica. Dos (1%) pacientes tuvieron un fallo parcial de la reparación y se sometieron a una reparación residual a los 6 meses.ConclusiónEl colgajo de túnica vaginal es un excelente refuerzo en la reparación de hipospadias severos. Es fácilmente accesible, sencillo de extraer, y su buena vascularización ayuda a reducir significativamente la incidencia de fistulización postoperatoria. (AU)

Introduction: Fistula following hypospadias repair remains a bane for the hypospadiologist resulting in the evolution of various techniques. Despite all these, the incidence of postoperative fistula varies between 10 to 30% and it increases with the severity of the hypospadias. Hence, a study was conducted to evaluate the efficacy of tunica vaginalis flap in preventing fistula formation following severe hypospadias repair.Materials and methodsAn observational study was carried out in a tertiary center between 2008 and 2017. The study included children with severe hypospadias (proximal penile, penoscrotal, scrotal, and perineal). In all the patients, a tunica-vaginalis flap was used to buttress the urethroplasty. All the patients were followed up for at least a year after the completion of treatment.ResultsA total of 210 patients were included in the study. Bracka's 2-stage repair was performed in 180 patients who had either penoscrotal hypospadias or a meatus even more proximal. The rest 30 patients with proximal penile hypospadias underwent a single-stage Snodgrass repair. Four (2%) patients developed a fistula, all following 2-stage repairs, and half of them required surgical repair. Two (1%) patients had a partial breakdown of repair and underwent a residual repair after 6 months.ConclusionThe tunica-vaginalis flap is an excellent buttress in severe hypospadias repair. It is readily available, easy to harvest, with its good vascularity helps to significantly reduce the incidence of postoperative fistula. (AU)

Bracka's two-stage repair was performed in 180 patients who had either Penoscrotal hypospadias or a meatus even more proximal. The rest 30 patients with proximal penile hypospadias underwent a single-stage Snodgrass repair. Four (2%) patients developed a fistula, all following two-stage repairs, and half of them required surgical repair. Two (1%) patients had a partial breakdown of repair and underwent a residual repair after six months. CONCLUSION: The Tunica-Vaginalis flap is an excellent buttress in severe hypospadias repair.

Does diagnostic delay lead invariably to damage in episodic pelvi-ureteric junction obstruction?

OBJECTIVE: To determine the relationship between the length of history and renal function in patients with symptomatic pelvi-ureteric junction (PUJ) obstruction in childhood. PATIENTS AND METHODS: The study included 41 children with symptomatic PUJ obstruction. The duration and details of their symptoms were recorded and the differential renal function estimated by isotopic renography. RESULTS: The median (range) duration of symptoms was 24 (0.25-84) months; there was no statistically significant relationship between the duration of symptoms and differential function at presentation (P=0.148). CONCLUSION: There is no correlation between the duration of symptoms and renal function in children with PUJ obstruction. A delay in diagnosis cannot be directly linked to permanent renal compromise.

Colorectal cancers in children without any predisposing factors. A report of eight cases and review of the literature.

Carcinoma of the colon is usually associated with conditions such as familial adenomatous polyposis, and ulcerative colitis. Primary carcinoma of the colon is very rare in children. A series of eight children with primary carcinoma of the colon is presented. The commonest symptom was right iliac fossa pain. All children had poorly differentiated, highly aggressive tumours. In spite of surgery and adjuvant treatment, the survival was dismal with all the children dying within one year of presentation.
