A novel upper tract ureteroscopic biopsy technique: the "form tackle"

Int. braz. j. urol; 48 (2), 2022
ABSTRACT Introduction and Objective: Upper tract urothelial carcinoma (UTUC) represents 5% of all urothelial malignancies (1-3). Accurate pathologic diagnosis is key and may direct treatment decisions. Current ureteroscopic biopsy techniques include cold-cup, backloaded cold-cup and stone basket (4-6). ...

Tabaquismo y tumores mayores de 2 centímetros son predictores de mortalidad en pacientes sometidos a nefro-ureterectomías por carcinoma de urotelio alto

Rev. méd. Chile; 150 (2), 2022
BACKGROUND: Upper urinary tract urothelial carcinoma (UTUC) represents 5-10% of urothelial carcinomas. It is managed with nephroureterectomy (NUR); however, kidney-sparing techniques are growingly used. AIM: To report the results of a 20-year series of NUR conducted in an academic center. Patients and Me...

Fibroblast growth factor receptor 3 gene (FGFR3) mutations in high-grade muscle-invasive urothelial bladder cancer in a Brazilian population: evaluation and prevalence

ABSTRACT Objective To understand the feasibility of FGFR3 tests in the Brazilian public health context, and to sample the mutational burden of this receptor in high-grade muscle invasive bladder cancer. Methods A total of 31 patients with high-grade muscle-invasive bladder cancer were included in the...

Synchronous presentation of muscle-invasive urothelial carcinoma of bladder and peritoneal malign mesothelioma

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Introduction Cancer is one of the most important leading cause of death in man and woman in the world. The occurrence of new cancer has become more frequent in recent years due to strict screening protocols and occupational and environmental exposure to carcinogens. The incidence of secondary ...

Can Neutrophil-to-Lymphocyte ratio predict the response to BCG in high-risk non muscle invasive bladder cancer?

Int. braz. j. urol; 45 (2), 2019
ABSTRACT Objectives: To evaluate the neutrophil-to-lymphocyte ratio (NLR) as a prognostic factor for response of high risk non muscle invasive bladder cancer (HRNMIBC) treated with BCG therapy. Materials and Methods: Between March 2010 and February 2014 in a tertiary center 100 consecutive patients wit...

Overexpression of UHRF1 gene correlates with the major clinicopathological parameters in urinary bladder cancer

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Introduction Recently, expression of the UHRF1 gene was found to be up-regulated in numerous neoplasms, including the urinary bladder transitional cell carcinoma (TCC). Objective The aim of our study was to determine if the expression levels of UHRF1 gene correlates with the major pathologic...

Radical cystectomy with pelvic lymphadenectomy: pathologic, operative and morbidity outcomes in a Brazilian cohort

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Introduction and Objective Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these feat...

Is [F-18]-fluorodeoxyglucose FDG-PET/CT better than ct alone for the preoperative lymph node staging of muscle invasive bladder cancer?

Int. braz. j. urol; 42 (2), 2016
ABSTRACT Objective: To evaluate whether the use of [F-18]-FDG-PET/CT can accurately predict pelvic lymph node metastasis in patients with muscle invasive TCC of the bladder undergoing radical cystectomy. Materials and Methods: Fifteen patients with muscle invasive bladder cancer had undergone FDG-PET/C...

Low grade urothelial carcinoma mimicking basal cell hyperplasia and transitional metaplasia in needle prostate biopsy

Int. braz. j. urol; 42 (2), 2016
ABSTRACT Purpose The vast majority of urothelial carcinomas infiltrating the bladder are consistent with high-grade tumors that can be easily recognized as malignant in needle prostatic biopsies. In contrast, the histological changes of low-grade urothelial carcinomas in this kind of biopsy have not bee...
