Objective: The objective of bladder augmentation (BA) is to create a low-pressure reservoir with adequate capacity. Despite its benefits, the use of intestinal patches in bladder enlargement provides a high risk of developing complications and BA with demucosalised bowel represents a potential alternative. Therefore, this study evaluated urological parameters and long-term clinical follow-up of patients submitted to nonsecretory BA in a single center with 25 years of experience.

Methods: Open, non-controlled clinical study of phase II. A total of 141 patients, among those children, adolescents and adults with hypospadias (112), epispadias (04), phymosis (13) and Peyronie's disease (12) that had a BC dressing applied over the operated area after surgery.
Introduction: One of the main problems faced by surgeons involved in male genitalia surgeries, in particular in children with hypospadias, is the type of dressing and its use during the post-operatory period.
Materials And Methods: From a multidisciplinary project involving the use of sugarcane biopolymer membrane developed in the last 10 years, produced by bacterial action over sugarcane molasses, we developed a multiperforated pellicle that, when applied around the penis, protects the surgical field. It is a proven inert material that does not induce any reaction on the surgical field and can be left in situ maintaining the same characteristics during a long period of time without the need of replacement.
Purpose: Children and young adults treated with augmentation procedures with total intestinal flaps are at increased risk for specific complications in the long term. The aim of the present study was to demonstrate the long-term results of demucosalized bladder augmentation.
Materials And Methods: A total of 183 patients (92 males and 91 females) were treated with bladder augmentation with the use of de-epithelialized intestinal segments.
Objective: To research technical alternatives for permanent gastrostomy that minimizes the drawbacks and complications reported by several authors.
Materials And Methods: An experimental model was developed where the material was divided into 2 groups: the study group (SG) composed of 12 half-breed dogs where the proposed technique was applied, and the control group (CG) composed of 10 animals where a gastrostomy as proposed by Webster in 1974 was applied. On the 90th postoperative day, both groups underwent tests for assessing competence concerning leakage.
Objective: To assess the value of the silicone modeler in preventing graft retraction in dogs undergoing bladder replacement with de-epithelialized ileum.
Materials And Methods: Twelve female dogs underwent total cystectomy and bladder replacement by neobladder made of demucosalized ileal segment, comparing the group with modeler (group I) and the group without modeler (group II). Cystometry data, graft epithelization and radiological assessment (cystography and excretory urography) were analyzed.
Purpose: We present long-term results on the use of demucosalized intestine for reconstructive surgery of the bladder.
Materials And Methods: A total of 129 bladder augmentations with demucosalized intestine were performed in 123 patients (55% males and 45% females) 3 months to 53 years old during the last 10 years. Of the patients 82 presented with neurogenic bladder, 40 with bladder exstrophy, 3 each with tuberculosis and posterior urethral valves, and 1 with female hypospadias.
Purpose: We report long-term followup of a new device for the treatment of urinary incontinence in children.
Materials And Methods: A periurethral constrictor was implanted in 29 boys and 13 girls 3 to 17 years old (mean age 10.2, median age 10) during the last 9 years.
