Anterior urethral polyp associated with hematuria in six-year-old child

Anterior urethral polyps are rare, occur only in male patients, and have been associated with obstruction, terminal hematuria, and enuresis. We believe this is the fifth reported case of anterior urethral polyp associated with terminal hematuria. The radiographic findings, treatment, and pathology are reviewed.

Treatment of urethral diseases with neodymium:Yag laser

Over a thirty-month period, a wide variety of common urethral problems were treated on an ambulatory basis, with the neodymium: yttrium-aluminum garnet (Nd: YAG) laser. When used discriminately, laser treatment appears to be an effective modality for the management of selected urethral strictures. Thus far, excellent results have been obtained in 30 of 31 cases of short strictures where laser urethrotomy was performed as the first stricture procedure (average follow-up 10 months). Furthermore, in a series of 36 cases of secondary bladder neck contractures, all of the evaluated patients responded well (average follow-up 7 months). Good results were obtained in only 11 of 48 complicated strictures (average follow-up 14 months). However, while most of these extensive strictures were not eradicated, laser therapy generally produced a documented clinical improvement, comparable to urethrotomy or dilatation, in 15 of these cases. A series of 24 condylomata involving the urethra were treated satisfactorily, with no recurrences (average follow-up 13 months). Laser treatment also has been used successfully for the management of several urethral caruncles, urethral polyps, two meatal hemangiomas, one urethral carcinoma, and a distal duplicated urethra. Recently, the Nd:YAG laser has been applied to the prostatic urethra with vaporization of obstructing median bar hyperplasia. Favorable results have been achieved in 5 of 6 cases treated with a newly developed technique that utilizes direct laser contact. Retrograde ejaculation has not been encountered in these patients (average follow-up 6 months). All of these procedures have been accomplished in the office, largely without urethral catheterization. Lidocaine jelly occasionally supplemented with intravenous sedation provided satisfactory anesthesia.

Prostatic‐type polyps of the lower urinary tract: three histogenetic types?

Seventeen prostatic-type polyps of the lower urinary tract are reported. All occurred in males, and the mean ages of the patients with ureteric orifice, bladder and urethral polyps were 20.5, 60.2 and 36.6 years, respectively. The commonest presentation for the bladder and ureteric orifice polyps was haematuria, whereas that for the urethral polyps was either dysuria or haematuria. The polyps consisted of acini and papillae lined by prostatic-type epithelium, as confirmed by immunostaining for prostatic-specific antigen. Most had interspersed islands or complete covering of transitional epithelium on the surface. We believe that the histogenesis of prostatic-type polyps may differ in the different sites. For the ureteric orifice polyp, the early age of presentation and the simple occurrence of prostatic acini beneath an intact urothelium suggest a developmental abnormality. For the bladder polyp, the late onset of disease and the commonly observed transition with cystitis cystica-glandularis suggest that it may be a metaplastic variant of cystitis cystica-glandularis. On the other hand, the urethral polyp probably represents a hyperplastic lesion, since the prostatic urethra is normally lined partly by prostatic-type epithelium.

Prostatic Urethral Polyp Causing Lower Urinary Tract Obstruction: Report of a Case

Polyps of the male urethra are relatively uncommon lesions. They usually arise from the prostatic urethra mostly verumontanum or Just lateral to the verumontanum. Posterior urethral polyp often presents with hematuria, hemospermia and sometimes lower urinary tract obstruction. We recently experienced a pedunculated prostatic urethral polyp in a 63-year-old man who complained of gross total hematuria and difficult micturition for several years. On rectal examination the prostate was slightly enlarged with normal consistency. Excretory urogram showed a round filling defect in the right side of the bladder neck measuring about in size. Cystourethroscopy revealed trabeculation of the vesical wall, mild bilateral prostatic hypertrophy and a round cystic mass with a long stalk arising from the prostatic floor 1 cm. Proximal to the verumontanum which caused ball-valve obstruction in the bladder neck. This pedunculated polypoid mass was then resected at its base with resectoscope and was removed transurethrally using Lowsley's grasping forceps. The specimen was proved as fibrous polyp histologically.

Benign polyps with prostatic-type epithelium of the urethra and the urinary bladder

The clinicohistologic features of seven urethral and four urinary bladder polyps with prostatic-type epithelium are described. The average age of the patients was 50 years. Seven patients had prior cystoscopies and in none of them was the lesion noted initially. Histologically the lesions were papillary or polypoid and the surface was lined predominantly by prostatic-type epithelium with interspersed transitional epithelial cells or by transitional epithelium with interspersed prostatic-type epithelial cells. The prostatic-type columnar cells contained foamy, faintly eosinophilic cytoplasm, which stained strongly for prostate specific antigen and prostatic acid phosphatase. In all the lesions, there were prostatic acini in the underlying fibrovascular stroma, which was devoid of smooth muscle. The intermingling of prostatic-type cells and transitional epithelium, on the surface of the polyps, the absence of lesions at previous cystoscopies, the coexistence of cystitis cystica glandularis (a metaplastic lesion), and the older age group of our patients suggest that the prostatic-type epithelium in the polyps of urethra and urinary bladder is an acquired lesion, most likely a metaplastic response of transitional epithelium, which embryologically was multipotential.

Congenital urethral polyp in children

Two cases of congenital urethral polyp are presented. The diagnostic value of voiding cystourethrography is emphasized.

Anterior urethral polyp in a child

Posterior urethral polyps are unusual but have been described on multiple occasions. 1,2 We are unable to find a report of a urethral polyp occurring in the anterior urethra of a child. A body with an anterior urethral polyp is the basis for this report.

Urethral Polyps in Male Children

One of the rare causes of intrinsic obstruction of the urethra in male children is the urethral polyp. Only two examples of this condition, one of which recurred six years after the original excision, have been recorded in our pediatric hospital. This rarity is consistent with the few cases reported in the current literature. In general, review articles on obstructive lesions of the lower urinary tract in children fail to mention polyps of the posterior urethra (11, 12). Campbell (1), Kjellberg (2), Rudhe (3), Flanagan (4), McCann (5), and Scott (6) report and discuss a single case, each. True et al. (7) discuss 2 cases, and Stephens (8) reports 5 in male children. The same abnormality has been described in an adult with secondary hydronephrosis by Barrie and Simms (9). None of these authors reported recurrence of a urethral polyp. Case Reports Case I: A 5-year-old boy had a single episode of hematuria one year prior to admission. One month before admission, symptoms of dysuria, pyuria, and frequency, as well as positive urine culture, were treated with antibiotics. On hospital admission, physical examination and laboratory studies were normal. An intravenous pyelogram showed a normal upper urinary tract and a large bladder diverticulum. A cinecystourethrogram demonstrated the diverticulum and a small filling defect in the base of the bladder. On micturition the diverticulum enlarged, and the polypoid filling defect descended from the bladder into the membranous urethra (Fig. 1). There was no vesicoureteral reflux. At suprapubic cystostomy, a thick-walled bladder, large diverticulum, and a “1-cm, firm, smooth, polyp on a 3-cm stalk” attached to the. verumontanum were encountered. The polyp, which had extended into the bladder through the vesical neck, was put on traction (Fig. 2), and the pedicle was transected at its attachment to the verumontanum. The diverticulum was removed, and the defect of the bladder wall closed in two layers. The pathologist reported an “inflamed non-neoplastic polyp.” Case II: A 6-year-old boy was admitted with a two-week history of hesitancy, dysuria, hematuria, and urinary retention. One year earlier, a similar episode had been treated with antibiotics. Physical examination and laboratory data were normal. Cystography demonstrated a filling defect at the base of the bladder (Fig. 3). On voiding, the filling defect descended through the dilated prostatic urethra and partially occluded the membranous urethra (Fig. 4). At cystostomy, a 2-cm polyp with its pedicle attached to the verumontanum was found. The polyp and most of the stalk were excised, the remaining stump withdrawing into the posterior urethra. The pathologist reported a benign, hamartomatous polyp lined with transitional and squamous epithelia, with an angiomatous and smooth muscle core. Three years following surgery, findings on follow-up cystoscopy were suggestive of a small, recurrent polyp.

Urethral polyp.

Polyps or papillomas of the urethra have been stated to occur in 1 per cent of boys undergoing urological examination (Campbell, 1951). They usually arise from or near the verumontanum. The majority are too small to be detected radiologically, and are seen at endoscopy. Cases diagnosed by cysto-urethrography are comparatively rare. 1,770 urethrocystrographic examinations made on 1,461 children by Kjellberg, Ericsson and Rudhe (1957) showed only one large urethral polyp. Stephens (1955) found two large polyps in 241 cysto-urethro-grams in 175 patients. In each case the polyp was pedunculated, arising from the region of the verumontanum. Stephens considered them to be of congenital origin.
