OBJECTIVE To assess the occurrence of upper urinary tract urothelial tumors (UUTT) in Brazil. MATERIALS AND METHODS We performed a clinical and histopathologic study of 33 patients who were diagnosed with a malignant neoplasm in the renal pelvis or ureter in the period of 1994 to 2004, in a single institution. RESULTS Among the patients with upper urinary tract carcinoma, 70% were males and...

BACKGROUND The aims of this study were to determine whether renal pelvis dilation on ultrasound was reliable in predicting vesicoureteral reflux (VUR) and to assess the relationship of other clinical information of VUR in children with urinary tract infection (UTI). METHODS We retrospectively reviewed clinical data, renal echo, and voiding cystourethrogram (VCUG) results in hospitalized child...

Millions of people worldwide are exposed to arsenic in drinking water. The International Agency for Research on Cancer has concluded that ingested arsenic causes lung, bladder, and skin cancer. However, a similar conclusion was not made for kidney cancer because of a lack of research with individual data on exposure and doseresponse. With its unusual geology, high exposures, and good informatio...

Although germline mutations of met proto-oncogene on human chromosome 7q31-34 have been known as useful molecular markers of hereditary papillary renal cell carcinoma (RCC), the expression of MET, a product of met proto-oncogene, has not been fully studied in sporadic RCC, along with its clinical significance. We investigated the expression of MET by immunohistochemistry in 182 cases of renal n...

Objective: Squamous cell carcinoma (SCC) of renal pelvis is a subtle tumor and pyelo-enteric and pyelo-cutaneous fistula has remotely been identified as its clinical presentation. This unseal clinical scenario is a diagnostic and management dissention. Method: We report a rare case of squamous cell carcinoma of the renal pelvis presenting as pyelo-enterocutaneous fistula in a patient with long ...

Extrapulmonary small cell carcinoma occurs in nearly all organs except the central nervous system and the liver. We are presenting a case of renal small cell carcinoma (SCC) with two unique characters. A 75-year-old patient was evaluated for back pain with no other complaints. Magnetic Resonance (MR) imaging of the abdomen revealed homogeneous tumor in the left renal pelvis extending beyond the...
