Background: Penile prostheses are the third option in the treatment of erectile dysfunction, however, despite their proven effectiveness, the occurrence of infections, advanced age of patients and comorbidities are the main limiting factors for this treatment modality. In the continuous search for biointegrated, clinically durable and minimally invasive treatment options, a possible model of penile prosthesis was sought through the use of intracavernous bacterial cellulose (BC) gel, in an experimental model of orchiectomized rabbits.

Methods: Thirty adult New Zealand rabbits were equally distributed into three groups: BC; vehicle and control.

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.

Aim: To evaluate the performance of the new device compared with clean intermittent catheterization (CIC).

Methods: From March 2015 to March 2018, patients who were admitted to the urologic outpatient clinic. A new intraurethral self-retaining device (ISRD) was made of medical grade silicone and it was inspired by similar catheters that use sliding disks to adjust or fix tubes used to drain the bladder.

Introduction: Urinary incontinence (UI) is a challenging problem for the urological community. Clean intermittent catheterization (CIC) is the most commonly used method to restore bladder emptying to the state close to the physiological condition. This procedure can cause negative aspects such as pain and possible urethral injury.

Purpose: To analyze the interaction between the cellulose exopolysaccharide (CEC) and urethral tissue when used as a pubovaginal sling.

Materials And Methods: Forty Wistar rats were divided into four groups. In groups A and B the cellulose exopolysaccharide (CEC) was implanted around the urethral tissue (bladder neck below the upper margin) and the rats were sacrificed at 30 and 90 days.

Objectives: We evaluated retrospectively, the long-term outcome of patients with post-prostatectomy urinary incontinence (PPUI) after placement of the Periurethral Constrictor (PUC).

Materials And Methods: Fifty-six men with severe PPUI were studied, with a mean age of 68.5 years old.

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.
