Polyps in the anterior urethra is very rare.,, Though so many cases of posterior urethral polyps have been reported, all of them are congenital in origin, but anterior urethral polyps may be congenital or acquired. Only one case of prolapsing anterior urethral polyp has been reported so far. Herein is a report of such a case of anterior urethral polyp, which prolapsed through the urethral meatus and diagnosed by ultrasonography.
| Case Report|| |
A 29-year-old man presented with something coming out through the urethra during micturation and narrow urinary stream, for the last few months. He had a past history of urethral surgery six years back, but all the records of that operation were lost.
On examination, he had a normal external genitalia and anterior urethral meatus. On retraction of the urethra, a red fleshy mass was coming out through the urethra. Retrograde urethrography demonstrated a filling defect in the anterior urethra. Ultrasonography of the urethra suggested a polyp attached on the ventral surface of the penile urethra [Figure - 1]. Urethroscopy showed a long pinkish mass of 3.5 cm, with a narrow stalk attached to the ventral surface of the urethra, with congested surface on the proximal portion of the mass. The polyp was resected transurethrally, on a low coagulation current. The histopathology showed a core of fibro vascular tissue covered with transitional epithelium, with some squamous metaplasia [Figure - 2]. Follow up cystoscopy after six months did not show any stricture in the urethra, or recurrence of the polyp.
| Discussion|| |
Posterior urethral polyp in boys has been reported in several occasions, but only twelve cases of fibro epithelial polyp of the anterior urethra is reported in the literature. Posterior urethral polyps are usually congenital in origin, but anterior urethral polyp may be congenital or acquired. Since 4 out of 8 adult cases among them were found during the postoperative follow up period of urothelial cancer, mechanical irritation by repeated transurethral procedures might be responsible for the development of fibro epithelial polyp of the anterior urethra in these cases. These polyps most commonly occur in infancy and childhood in the first decade of life, but rarely occur in aged males. They usually present with dysuria, hesitancy, enuresis, post-void dribbling, terminal haematuria, or gross haematuria. Urinary retention or back pressure changes in the upper tract is a common feature in the posterior urethral polyp, but only one reported case of anterior urethral polyp was presented with acute urinary retention. Retrograde urethrography or urethroscopy is the mainstay of diagnosis, but ultrasonography is a valuable tool of diagnosis as in this case. Transurethral resection of the polyp is the treatment of choice with minimum morbidity.
