“…CT can reveal soft tissue filling the UPJ and proximal ureter, and images may be clearer and viewed directly by enhancement and 3D reformations. So, it may be valuable to depict more precisely the relationship of the fibroepithelial polyp with the ureteral wall and to confirm the absence of periureteral invasion [12,13]. However, in this series, most images of IVU, US and CT cannot reveal the polyps and are just like the images of hydronephrosis caused by stenosis and blood vessel aberration.…”

Ureteral polyps: an etiological factor of hydronephrosis in children that should not be ignored

et al. 2007

To better define the demographics, urothelial distribution and typical gross anatomic and radiologic appearances of fibroepithelial polyps of the ureter in children. We reviewed 15 cases of fibroepithelial polyps of the ureter with hydronephrosis from the archives of our department. Data were collected from radiographic studies, gross anatomic pathology and pathology and radiology reports and categorized by age, sex, clinical presentation, lesion size and location. The mean patient age was 9.1 years, and 80% were male. All of them presented with hematuria and/or flank pain. The polyps were located in the upper ureter or ureteropelvic junction (UPJ) and pelvis. Of the polyps, 60% were multiple polyps or filiform, and 40% were single or bilobed and 1-6 cm in size. Only four cases showed typical filling defect on intravenous urography. In five cases, sonography showed a mildly echogenic structure extending into the ureter from the renal pelvis. Enhanced CT revealed soft tissue filling UPJ or/and proximal ureter in six cases, and hydroureter was found in one case by three-dimensional (3D) image. Fibroepithelial polyps were diagnosed in all cases by postoperative histological examination. Fibroepithelial polyps are the most common benign tumors of the ureter. Congenital factor may be associated with the origin of fibroepithelial polyps in children. The preoperative diagnosis of ureteral polyps is difficult. A history of flank pain, hematuria or both, other than abdominal mass, light-to-moderate hydronephrosis with soft-tissue in UPJ or upper ureter, shown by sonography and radiological examination, may help in the diagnosis of ureteral polyps in children. Ureteral polyps should be recognized as an important etiology for hydronephrosis in children.

“…CT is particularly useful to differentiate bladder polyps from those arising from lower ureter near ureterovesical junction. 11 However, cystoscopy is a key investigation in the diagnosis as it allows for both diagnostic and therapeutic modality of treatment. The final diagnosis rests on histopathology report particularly to differentiate it from rhabdomyosarcoma and transitional cell carcinoma which have been reported in paediatric age group.…”

Benign fibroepithelial bladder polyp: a rare cause of childhood haematuria

et al. 2018

View full text Add to dashboard Cite

Haematuria in paediatric population is common yet alarming. It warrants a thorough physical examination and other investigations. Of late, a number of extremely rare aetiology of childhood haematuria have come to forefront. One such uncommon cause is benign fibroepithelial urinary bladder polyp. The presentation is of a child with intermittent haematuria exacerbated by physical/sports activity associated with or without suprapubic pain. Diagnosis is usually made by ultrasonography and cystoscopy and confirmed by histopathological examination. Treatment is surgical and involves cystoscopic transurethral resection of the mass. The exact aetiology of benign fibroepithelial polyp is uncertain with no clear guidelines on long-term surveillance. However, these cases should be subjected to cystourethroscopy if haematuria recurs. Treatment is surgical with good long-term prognosis. Not much is written in literature about benign fibroepithelial bladder polyp.

“…Hematuria is the most common presenting symptom, although other urinary symptoms may be found. 4 Although the radiological appearance of fibroepithelial polyps is highly variable, they are frequently diagnosed exclusively by means of intravenous urography and/or retrograde ureterography. Polyps are usually viewed as long, slender and generally smooth filling defects, frequently found in the proximal ureter and sometimes associated with hydroureteronephrosis.…”

Ureteral fibroepithelial polyps in a pregnant woman: case report

et al. 2009

CONTEXT: Ureteral fibroepithelial polyps are rare benign nonepithelial tumors, and less than 200 cases have been reported in the literature. We report on a pregnant patient with ureteral fibroepithelial polyps that were successfully treated with laparotomy. CASE REPORT:A 23-year-old pregnant woman presented with a three-month history of intermittent lumbar pain of low intensity. Abdominal ultrasonography showed that she was 13 weeks pregnant and found severe left-side ureterohydronephrosis and a heterogeneous solid mass measuring 11 x 8 x 7 centimeters in the middle portion of the ureteral topography. The investigation was complemented with magnetic resonance imaging, which confirmed the previous findings. Nephroureterectomy was performed without complications. The specimen revealed three solid tumors in the ureter, of which the largest was around eight centimeters in length. The anatomopathological report confirmed that they were fibroepithelial tumors without malignant components. RESUMOCONTEXTO: Pólipos fibroepiteliais de ureter são tumores não-epiteliais benignos raros, e menos de 200 casos foram relatados na literatura. Nós reportamos o caso de uma mulher grávida com pólipos fibroelitelial ureteral que foram tratados com sucesso por laparotomia. RELATO DE CASO:Mulher de 23 anos de idade, grávida, apresentava história de dor lombar intermitente de baixa intensidade há três meses. Ultrasonografia abdominal revelou gravidez de 13 semanas, ureterohidronefrose grave à esquerda e massa sólida heterogênea medindo 11 x 8 x 7 cm na porção média da topografia ureteral. A investigação foi complementada com ressonância magnética, que confirmou os achados. Foi realizada nefroureterectomia sem complicações. A peça revelou três tumores sólidos em ureter, o maior apresentando aproximadamente oito centímetros longitudinalmente. O relatório anatomopatológico confirmou tumor fibroepitelial sem componentes de malignidade. KEY WORDS:Laparotomy.Neoplasms.Pregnant women.Ureter.Urology. PALAVRAS-CHAVE:Laparotomia.Neoplasias.
