Transurethral resection of pedunculated congenital polyps of the posterior urethra

Urethral polyp in neonate: a rare occurrence

Polyps of urethra as well as those in an anterior urethra in a male neonate are a rare abnormality, hence this publication. They usually present as either obstructive urinary symptoms in males or as an intralabial mass in females (Raviv G, Leibovitch I, Hanani J, et al., Hematuria and voiding disorders in children caused by congenital urethral polyps: principals of diagnosis and management. Eur Urol 1993;23:382.

URETHRAL POLYPS IN PREPUBERTAL GIRLS

PURPOSE

Urethral polyps in girls are included in the differential diagnosis of interlabial masses. Only 6 cases have been described in the English literature to date and etiology is uncertain. We present 5 more cases and review the literature. We also propose an etiology for urethral polyps in young girls and compare polyps between girls and boys as well as older females.

MATERIALS AND METHODS

The medical records of prepubertal girls with urethral polyps seen at our hospital between 1980 and 2003, including operative reports and followup, were reviewed. A senior pathologist re-inspected the specimens to confirm the diagnosis. A MEDLINE search of urethral polyps was performed.

RESULTS

We identified 5 girls 2 to 10 years old with urethral polyps. All girls presented with "vaginal" bleeding, 1 had recurrent urinary tract infections and vulvitis, 1 had urinary frequency, and 1 had painful voiding. The polyps were not site specific and were located in the distal, mid and proximal urethra. All polyps were excised and were found benign. Four girls were cured after 1 procedure, while in one girl the polyp reappeared. The patients were followed for 1 to 17 years and eventually became asymptomatic.

CONCLUSIONS

Urethral polyps in prepubertal girls are probably benign. We suggest that the etiology of most of polyps in girls is similar to those in older females, that is a prolapsing urothelium that has evolved into a polyp.

Haemangiomatous polyp of the posterior urethra in a boy

Urethral haemangiomas are rare and usually involve the entire urethra or are localized to the anterior urethra. Posterior urethral polyps are uncommon. A posterior urethral polyp was removed from a 3-year-old boy which proved to be haemangioma. In the histological classification of posterior urethral polyps, haemangioma should therefore be included.

Transitional cell carcinoma of the bladder in children: radiologic appearance and differential diagnosis

Primary epithelial tumors of the bladder are rare in children. We report a case of transitional cell carcinoma (TCCa) of the bladder in a 10-year-old boy who was evaluated with intravenous urography, ultrasonography, and computed tomography (CT). The radiographic appearance and a differential diagnosis are discussed. The literature of TCCa of the bladder in children is reviewed.

Congenital posterior urethral polyps

Congenital posterior urethral polyps are benign growths that can cause a variety of symptoms in young boys. They are pathologically distinct growths usually discovered by voiding cystourethrography. We present 5 cases of congenital posterior urethral polyps, and discuss the presentation and pathophysiological status of these lesions. These lesions must be considered in the differential diagnosis of voiding dysfunction in young boys.
