cystoscopy and urinary cytology are currently the basis for diagnosis and ‎follow-up of bladder tumors. research to find a sensitive and specific tumor ‎marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity ‎and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder ‎cancer (ubc) antigen level can ...

small cell carcinoma of the urinary bladder (sccub) is an extremely rare bladder malignancy characterized by an aggressive clinical behavior. so, it is important to diagnose this high grade disease by urinary cytology. we report a case of sccub in an old man with chronic lymphocytic leukemia (cll) in remission, while bladder tumor was diagnosed by cytology. with this article, we aimed to review...

We evaluated the need for transurethral biopsy at first follow-up after intravesical bacillus Calmette-Guerin (BCG) therapy for superficial bladder cancer. The records of 84 patients with superficial bladder cancer who received a 6- or 8-week course of BCG were reviewed. Pathological results before BCG, cystoscopic findings, urinary cytology, and biopsy results for evaluation of BCG therapy wer...

BACKGROUND We determine the utility of serial urinary cytologies in patients presenting with microscopic hematuria who were evaluated with upper and lower urinary tract studies to rule out a malignancy. METHODS Two hundred and thirty-seven patients with the diagnosis of microscopic hematuria were evaluated at an inner-city tertiary care hospital. Of these 239 patients, 182 patients had 405 cy...

We evaluated the usefulness of urinary nuclear matrix protein 22 (NMP22) compared to urinary cytology in the detection of urothelial transitional cell carcinoma (TCC). Between July 1999 and March 2000, 227 patients complaining of microscopic or gross hematuria were analyzed. Twenty-four patients (10.6%) had urothelial TCC. The urinary NMP22 level was significantly higher in the patients with ur...

AIMS To define the natural history of patients with suspicious urinary cytology and negative initial evaluation for malignancy in the investigation of haematuria. PATIENTS AND METHODS Data from the hospital information support system on urinary cytology examinations carried out at one centre were audited over a period of 24 months. There were 102 patients who had suspicious urinary cytology f...

OBJECTIVES The sensitivity of voided urinary cytology has been reported as very low. In this study, we investigated the sensitivity and clinical utility of voided urinary cytology in the detection of various grades and stages of transitional cell carcinoma (TCC) of the bladder compared with the urinary nuclear matrix protein-22 (NMP-22) qualitative assay. METHODS From March 2004 to April 2006...

OBJECTIVE To verify the indication of diagnostic ureteropyeloscopy based on clinical features for upper urinary tract urothelial cancer with over 100 patients and over a 10-year series. METHODS From January 1997 to December 2008, consecutive 129 units in 124 patients underwent ureteropyeloscopy to obtain a definitive diagnosis of upper urinary tract cancer or to rule out a malignancy. Patient...

opium use is one of the most common forms of substance abuse in iran and there are some evidence indicating it is a risk factor of transitional cell carcinoma (tcc) of the urinary bladder. the majority of opium users are also cigarette smokers, so consideration of the high prevalence of smoking which is the most important risk factor of tcc of the urinary bladder among opium users is essential ...
