A Distal Ureteral Fibrous Polyp and the Role of Ureteroscopic Resection in Its Management

Fibroepithelial polyps of the ureter are rare benign mesodermal tumors that occur most often in the proximal ureter. We describe a case of a fibrous polyp in the distal ureter and discuss the role of ureteroscopic resection in the management of this condition.

Benign ureteral polyp as a cause of obstruction in a child

In a 9-year-old boy with intermittent flank pain and microhematuria, ureteral obstruction due to multiple fibroepithelial polyps was diagnosed by means of radiologic studies and surgical exploration. The benign nature of the lesions and the need for conservative surgery is stressed.

Hydronephrosis due to Fibroepithelial Ureteral Polyp in a Child

The case of a 5-year-old girl, complaining of left abdominal and flank pain, is reported. The excretory urogram and retrograde pyelography showed an obstruction located at the left upper ureter with hydronephrosis. Exploration revealed a small ureteral polyp obstructing the lumen. The polyp along with the short segment of the ureter was resected. Diagnostic and therapeutic considerations are discussed.

Ureteral fibroepithelial polyp with positive urinary cytology

We report on a patient with two fibroepithelial polyps of the upper ureter in whom the correct diagnosis was confused by finding voided urine as well as ureteral wash, and brush biopsy cytologies positive for malignancy. Fibroepithelial polyps and causes of falsely positive urinary cytology are reviewed.

An unusual case of pelviureteric junction obstruction

We describe an unusual case of pelviureteric junction obstruction in a child due to a benign ureteric polyp. Benign neoplasms of the ureter are uncommon in adults and extremely rare in children.

上部尿路疾患へのレーザー応用

From October 1986 to October 1992, Six patients were evaluated for ureteroscopic treatment in combination with Nd: YAG laser treatment of upper urinary tract tumors. Tow patients had benign ureteral polyps. 4 patients had transitional cell carcinoma. Two Patients with polyp were only treated ureteroscopycaly. 4 carcinoma patients were treated 5 times by laser. One patient had local recurrence and 1 patient had high grade bladder tumors and multiple ureter tumor. Finally both of these patients were treated by nephroureterectomy. Of 5 patients with ureteral tumors who were believed to be candidates for endoscopic therapy, 4 were controlled by this method of treatment. In selected individuals ureteroscopic laser treatment of upper urinary tract transitional cell carcinoma can achieve local control with renal preservation.

Bilateral fibroepithelial polyps of ureter in a child

Presented here is the first case of bilateral ureteral polyps in a patient under eighteen years of age, with vivid colored intraoperative photographs. The importance of careful identification of the base of the polyp to reduce operative morbidity and the necessity of ureteral reanastomosis rather than simple excision of the polyp in children is emphasized.

Vascular polyps of ureter associated with megacalycosis and nephrolithiasis

Multiple benign vascular polyps of the ureter are rare, and the associated congenital megacalycosis and nephrolithiasis are very uncommon. Herein we report a case with vascular polyps of the right ureteropelvic junction dissociated with extensive hydronephrosis which was considered to be megacalycosis. Clinical features and treatment modalities are reviewed.

Benign fibrous ureteral polyps

Benign fibrous polyps of the ureter are rare. A review of the English literature since 1930 revealed that 71 cases had been described. Three additional cases of fibrous ureteral polyps, one in a ureter with ureteritis cystica, are reported with a discussion of both the histologic findings and proposed treatment plan.

276 - Endoscopic Management of Large Distal Ureteral Polyp as an Out-Patient

Abstract This video describes the minimally invasive technique of removing a 5 cm distal ureteral polyp close to 25 years ago with the use of ureteroscopy and a polyp snare. It is of historical sig...

Ureteral Polyps Presenting as Ureteropelvic Junction Obstruction in Children

We report on 2 children with fibroepithelial polyps. The benign nature of this lesion is discussed and the role of conservative surgical treatment is emphasized.

Angiomatous ureteral polyp

A case report of a benign ureteral polyp is presented. Treatment consisted of local excision. The follow-up has been uneventful.

Analgesic nephropathy associated with an inflammatory ureteric polyp

Analgesic nephropathy associated with an inflammatory ureteric polyp

INFLAMMATORY URETERIC POLYP ASSOCIATED WITH ANALGESIC NEPHROPATHY

A cace of inflammatory ureteric polyp in a patient with analgesic nephropathy is reported. The pathological similarities to ureteric stricture associated with analgesic nephropathy are detailed, and a possible relationship of these polyps to strictures is suggested.

Fibrous polyp of the ureter.

The most frequent ureteral tumors are transitional carcinoma. Benign neoplasms are uncommon. In this paper we present 6 cases of ureteral polyps, which represent 11.1% of all the tumors in our series of ureteral tumors. We have reviewed the possible etiopathogenesis and exposed the clinical characteristics. Secondary to the obstructive phenomenon and the radiologic signs, it is the tigroid appearance, the localization and the absence of total obstruction which allows the diagnostic suspicion. The treatment of choice is partial resection. Ureterostomy with peroperatory biopsy, in cases in which the malignancy is not yet established, is recommended in order to avoid unnecessary nephroureterectomies.

Fibrous ureteral polyps.

Twelve cases of fibrous ureteral polyps are presented, illustrating their characteristic radiographic appearances. Two types--a long pedunculated mobile variety having a smooth surface, and a relatively shorter lesion covered with thin, finger-like projections--may be identified. Demonstration of the typical findings on excretory urography and/or retrograde ureterography establishes the diagnosis and permits surgical conservatism. Although no sex preponderance was noted, a wide sex-related age disparity was observed, the involved males being much younger than the females.

Ureteric polyp as a cause of hydronephrosis in childhood

Obstruction of the ureteropelvic junction from a polypoid lesion is considered to be an exceedingly rare cause of hydronephrosis in childhood.

原発性尿管線維脂肪腫の1例

A case of primary ureteral fibrolipoma is reported in this paper. The patient was a 50-year-old Japanese male who was admitted to the Kitasato University Hospital in April 1974, complaining gross hematuria and right flank pain of two months' duration. Excretory and retrograde urography revealed a large mass in the right ureter at the level of lumbosacral joint. Right nephroureterectomy was performed and the surgical specimen revealed a long convoluted yellowish-white tumor mass, 6×1.5cm in size, with a small stalk in the lower third of the right ureter. Histological diagnosis of the mass was fibrolipoma.Tumors of non-epithelial origin are exceedingly rare except for ureteral polyps. The first case of primary ureteral fibrolipoma was reported by Cohn in 1932. No other cases have been reported so far to our best knowledge. Our case is believed to be the second in the literature.

Bilharzial (schistosomal) ureteritis cystica

We have reported on one aspect of bilharzial ureteritis, namely, ureteral polyps. Herein we report our experience with a different pathologic entity, ureteritis cystica. A clinical, radiologic, and pathologic evaluation is presented. The differentiating points between polyps and cysts are presented.
