Risk and protective factors for secondary procedures after endoscopic dilatation of primary obstructive megaureters.

Purpose: High-pressure balloon dilatation (HPBD) of the ureterovesical junction with double-J stenting is a minimally invasive alternative to ureteral reimplantation or cutaneous ureterostomy for first-line surgical treatment of primary obstructive megaureter (POM). The aim of our study was to identify the risk factors associated with the need for secondary procedures due to HPBD failure.

Methods: Prospective data were collected from patients who underwent HPBD for POM between 2007 and 2021 at a single institution.

A novel therapy for idiopathic urethritis in children: Local steroid injection.

Idiopathic urethritis (IU) is difficult to manage and there is no standarized therapy. The technique of local steroid injection (LSI) for the treatment of IU in children and the results of the patients undergoing LSI from 2020 to 2021 in a single center are presented. Seven patients with IU underwent LSI.

Distal Urethral Advance and Glanduloplasty (DUAGPI) for Distal Hypospadias: A 15 Years Experience.

Background: Meatal advancement with glanduloplasty (MAGPI) has been in the recent years one of the most frequently surgical techniques used for the correction of distal hypospadias. Multiple modifications have been described to improve the results ofthis technique. In 2004 we presented the initial results of the New Modern MAGPI or DUAGPI (distal urethral advancement and glanduloplasty) as a surgical alternative to the original MAGPI.

Estimado Editor: Escribimos esta carta en relación al artículo publicado en su revista el pasado mes de Julio de 2020, por Castro-Díaz et al., titulado "Perfil de severidad sintomática y expectativas en pacientes con vejiga hiperactiva. Estudio VHEXPECTA" (1), y que hemos leído con gran interés.

Update on sacral neuromodulation and overactive bladder in pediatrics: A systematic review.

Objectives: Sacral electrical stimulation has been used for more than a century as an alternative therapy for adult urinary syndromes. In the literature, several studies have validated the efficacy of this technique based on clinical and urodynamic criteria. Nevertheless, few studies have shown beneficial results in children with overactive bladder.

Transcutaneous sacral electrical stimulation versus oxibutynin for the treatment of overactive bladder in children.

Background: Nowadays there is still no ideal treatment for paediatric overactive bladder. Initial management measures (urotherapy and constipation control), resolve 40% of cases. The second line of treatment in overactive bladder is anticholinergic drugs, above all oxybutynin.

Dermal regeneration sheet Integra® in management of recurrent Urethrocutaneous fistula after hypospadias surgery.

Background: Urethrocutaneous fistula UCF is the most common complication following surgical repair of hypospadias. Currently, the surgical technique mostly used to prevent recurrence employs preputial dartos or testicular tunica vaginalis flaps as a urethral covering. However, autologous tissues are limited in patients with multiple surgeries, and the use of biomaterials as a urethral coverage may represent a good alternative.

Estimado Editor: Escribimos esta carta en relación al artículo publicado en su revista el pasado mes de Diciembre de 2017, por Tardáguila Calvo et al., titulado "Reconstrucción genital con dermis artificial Integra® tras resección radical en un niño con linfangiomatosis difusa" (1), y que hemos leído con gran interés. A propósito de este trabajo creemos conveniente ampliar la información de los autores compartiendo nuestra experiencia previa (2,3).

[Comparative analysis of the treatment of mid-shaft and distal hypospadias according to Snodgrass surgical repair and Mathieu technique.].

Objective: The objective of this study is to perform an analysis of the patients who underwent middle and distal penile hypospadias repair using the two most widely used techniques in our Pediatric Urology Unit. MATERIAL AND METHODS: We perform a retrospective analysis of patients with a diagnosis of middle penile and distal penile hypospadias and operated by the Snodgrass or Mathieu technique, between 2011 and 2016 ensuring minimal follow-up of one year. We will analyze the use of each one, the results obtained, and the possible factors that could influence their success rate.
