RAMIREZ BACKHAUS, M. et al. Urethral diverticulum: Our casuistic and the literature review. Actas Urol Esp [online]. 2007, vol.31, n.8, pp.863-871. ISSN 0210-4806.

Purpose: The possible etiopathogenic factors, symptoms, diagnostic methods, surgical management and complications of the urethral diverticula are reviewed. Materials and methods: A retrospective study of the clinical charts with urethral diverticula diagnosis during the period 1986-2006 was carried out. Results: In the last 20 years a total of 19 patients have been treated for this pathology: 15 females and 4 males. Five of the females started with a sensation of vaginal mass; the rest were diagnosed of micturitional (irritative) syndrome, urinary incontinence or urinary infection. In the case of males, 3 of them had a palpable tumour in the penis. The most used diagnostic method was retrograde and voiding cystourethrography; urethrography with double-occlusion balloon catheter was used in 5 cases and urethroscopy in 4 patients; other techniques of image diagnosis like magnetic resonance imaging were necessary for the most complex cases. The treatment was the excision of the diverticulum, except for one of the females who rejected the treatment. The evolution in all treated women was successful, according to follow up 2 years after the treatment. In males, two of them had complex recurrent diverticula. Conclusions: Urethral diverticula are nosologic entities of difficult diagnosis, due to their low prevalence and their unspecific clinic, therefore diagnosis is sometimes incidental. The etiopathogenity is acquired in most cases and its surgical treatment is more challenging in males than in females probably linked to the fact that diverticula appear in urethras with previous surgery, endourologic manipulation or associated injuries.
