Urethral reconstruction

Abstract

Aurethral stricture is an abnormal narrowing of the urethra due to spongiofibrosis of the urethral mucosa and the underlying corpus spongiosum. The diagnostics include uroflowmetry, sonography and radiology. For penile strictures the success rate of endoscopic treatment is low. Therefore, urethroplasty should always be performed, preferably using oral mucosa. Depending on the complexity, reconstruction must be carried out in one or multiple stages. For short bulbous strictures endoscopic treatment can primarily be carried out. In the case of recurrence urethroplasty should be carried out. The indications for urethral reconstruction are primarily given for long bulbous strictures. Depending on the length and extent of the stricture, ascar resection and end-to-end anastomosis, non-transsecting end-to-end anastomosis or augmentation urethroplasty can be performed. Perineal urethrostomy (the so-called boutonnière procedure) is atreatment option for patients with complex strictures or for patients who want astraightforward solution.
