primary ureteral neoplasms are very rare and its prevalence is less than 1% of all genitourinary neoplasms. we report a symptomatic giant ureteral fibro epithelial polyp in adult women presenting as a bladder mass which was resected ureteroscopically and reported at the first time from iran. cystoscopy is growing use in the treatment of urinary tract lesions cystoscopy can be used in large lesi...

Background: Carcinoid tumors usually originate from the enterochromaffin cells located in gastrointestinal tract and bronchopulmonary system. They may rarely arise in the urinary bladder, where this can be eventually miscued as any other commoner bladder neoplasms. The current study was conducted to connote an uncommon clinicopathological presentation by a carcinoid tu...

background: the gold standard for detection of bladder cancer is cystoscopy, which is an invasive and complicated procedure. our study was conducted to find a tumor marker with high specificity, sensitivity, and accuracy for the diagnosis of bladder cancer. methods: serum samples were collected from 58 bladder cancer patients and 60 healthy control subjects. levels of lipid-bound sialic acid (l...

Saccharin is carcinogenic for the urinary bladder in rats and mice, and most likely is carcinogenic in human beings. The neoplasms of the urinary bladder are malignant and invade and metastasize. Male rats are more susceptible to urinary bladder carcinogenesis than female rats. Rats exposed as fetuses develop neoplasms more readily than rats exposed as weanlings. The lesions in the urinary blad...

Background & Aims: In the western countries, bladder cancer is the fourth and eighth common cancer in males and females, respectively, and like other cancers it has been significantly increasing in last years. The aim of this study was to find out the epidemiology of bladder cancer in Fars province /Iran during 2003-2008 according to cancer registry data system. Methods: In this epidemiological...

BACKGROUND Uro-oncological neoplasms have both a high incidence and mortality rate and are therefore a major public health problem. The aim of this study was to evaluate research activity in uro-oncology over the last decade. METHODS We searched MEDLINE and ClinicalTrials.gov systematically for studies on prostatic, urinary bladder, kidney, and testicular neoplasms. The increase in newly publ...

Mucinous neoplasms of the urinary tract are very rare. We present a 63-year-old-women who had a sessile papillary villous tumor in urinary bladder. Although transurethral resection of the bladder tumor (TURBT) was performed, the villous tumor repetitively recurred and gradually spread to the entire surface of bladder lumen. Histopathologic and immunohistochemical examination showed that the les...

BACKGROUND Light microscopic evaluation of cell morphology in preparations from urine or bladder washing containing exfoliated cells is a standard and primary method for the detection of bladder cancer and also malignancy from other parts of the urinary tract. The cytopathologic examination is a valuable method to detect an early recurrence of malignancy or new primary carcinoma during the foll...
