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.

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.

Influence of constipation on enuresis.

Introduction: Constipation has classically been considered as a risk factor of enuresis, although there are increasingly more publications that report a similar prevalence of constipation in both enuretics and non-enuretics.

Objective: To determine the influence of constipation in monosymptomatic and non-monosymptomatic enuresis, and to find out the prevalence of the three disorders, as well as the lower urinary tract dysfunction and bladder-bowel dysfunction in the population.

Material And Method: A cross-sectional observational prevalence study on a representative population sample of 5-9 year-old school boys and girls of Galicia, Spain.

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.

[Prevention, diagnosis and treatment of necrotising enterocolitis in newborns less than 32 weeks at birth in Spain].

Objectives: To describe preventive, diagnostic and therapeutic strategies regarding necrotising enterocolitis in Spain and to identify the strengths, areas of further improvement, and future research lines.

Methods: Two questionnaires on the management of preterm infants less than 32 weeks, at risk of, or with diagnosed necrotising enterocolitis, were distributed among selected representatives of the surgeons and neonatologists of the Spanish Neonatal Network (SEN1500) participant hospitals with a Paediatric Surgery Department.

Results: Percentage of response was 77.

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.

[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.

Atypical presentation of Leydig cell tumour in three prepubertal patients: diagnosis, treatment and outcomes.

Background Testicular tumours are uncommon in children, accounting for only 1% of all childhood tumours. Prepubertal Leydig cell tumours actively secrete testosterone and as a result, patients typically present with isosexual precocious pseudopuberty, this being the first cause of consultation. We present three cases of Leydig cell tumours in prepubertal patients with an atypical presentation.

[Analisys of non-neurogenic lower urinary tract dysfunction patterns controlled in a Pediatric urodynamic unit.].

Objectives: Between 7-10% of schoolagechildren are seen by specialists for non-neurogeniclower urinary tract dysfunction (LUTD). The objective ofour study is to classify these functional alterations in difused for the diagnosis and treatment in each pattern.

Material And Methods: We reviewed patients referredto our Urodynamic Unit for suspected LUTD for3 years; We reviewed epidemiological data, supplementarytest and treatments.

[Validation of the spanish version of the pediatric lower urinary tract symptoms scale (PLUTSS).].

Objectives: Lower Urinary Tract Dysfunction (LUTD) is the most common clinical problem in pediatric urology. To our knowledge non-validated instruments properly designed to screen lower urinary tract symptoms in the pediatric population has been translated and adapted to Spanish population. Pediatric Lower Urinary Tract Symptoms Score (PLUTSS) has proven to be a valid questionnaire for screening and evaluation of the response of children with LUTD to therapy.

[Predictive value of ureteral dilation rate in the success of endoscopic correction of vesicoureteral reflux in pediatric patients].

Objectives: 30-50% of pediatric patients with the diagnosis of lower urinary tract infection (UTI) have vesicoureteral reflux (VUR). The endoscopic treatment of VUR has become one of the main therapeutic tools and its success has been traditionally related to the grade of VUR. Nevertheless, in each of the VUR grades different grades of ureteral dilation may be observed.

[Use of a urethral plate in surgery for incurving hypospadias].

Objective: To describe a new procedure for surgical correction of primary hypospadias with chordee.

Methods: The design of the urethral plate divide it in two flaps. Chordee must be resected in order to straighten the penis.
