Preditores de mortalidade em pacientes submetidos à nefrectomia por carcinoma de células renais não metastático em um centro de referência no Nordeste Brasileiro

Rev. Col. Bras. Cir; 44 (3), 2017
RESUMO Objetivo: identificar fatores prognósticos envolvidos no carcinoma de células renais não metastático. Métodos: estudo tipo coorte retrospectivo, utilizando dados obtidos em revisão de prontuários de pacientes portadores de carcinoma de células renais, submetidos à nefrectomia radical ou...

Open partial nephrectomy for entirely intraparenchymal tumors: a matched case-control study of oncologic outcome and complication rate

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Purpose To compare the oncologic and clinical outcomes for open partial nephrectomy (OPN) performed in patients with entirely intraparenchymal tumors versus case-matched controls, with exophytic lesions. Material and methods Patients having undergone OPN between 2007 and 2012 were investigat...

The percentage of resected and ischemic volume determined by a geometric model is a significant predictor of renal functional change after partial nephrectomy

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Purpose The percentage of parenchyma preserved plays a predominant role in predicting renal function after partial nephrectomy (PN). Currently there is no standard method to estimate preserved renal parenchyma. In this study we propose a formula of the percentage of resected and ischemic volum...

Clinical significance of preoperative neutrophil -to - lymphocyte ratio in renal cell carcinoma

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Introduction: We investigated the prognostic significance of the neutrophil-to-lymphocyte ratio on tumor stage and Fuhrman nuclear grade in renal cell carcinoma. Methods: The records of 432 patients with RCC who underwent radical or partial nephrectomy between 2005 and 2014 were retrospectivel...

Functional and oncologic outcomes after nephron-sparing surgery in a solitary kidney: 10 years of experience

Int. braz. j. urol; 42 (2), 2016
ABSTRACT Objectives: To evaluate functional and oncologic outcomes of partial nephrectomy (PN) in patients with a solitary kidney. Materials and Methods: A retrospective analysis of patients with a solitary kidney undergoing nephron-sparing surgery between March 2003 and March 2013 was performed. GFR w...

Urothelial neoplasm of the bladder in childhood and adolescence: a rare disease

Int. braz. j. urol; 42 (2), 2016
ABSTRACT Purpose: Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents. Materials and Methods: We c...

Three-dimensional reconstructive kidney volume analyses according to the endophytic degree of tumors during open partial or radical nephrectomy

Int. braz. j. urol; 42 (1), 2016
ABSTRACT Objectives To investigate the renal function outcomes and contralateral kidney volume change measured by using a 3-dimensional reconstructive method after open partial nephrectomy (PN) or open radical nephrectomy (RN) according to the endophytic degree of tumors. Materials and Methods We inc...

Hipernefroma gigante: a propósito de un caso
Giant hypernephroma: apropos of a case

Rev. cuba. cir; 47 (1), 2008
El hipernefroma constituye el 3 por ciento de todos los tumores malignos y es el tumor renal más frecuente del adulto. Se sospechaba la existencia de un carcinoma renal ante la presencia de hematuria, lumbalgia y tumor abdominal palpable. En la actualidad, el empleo sistemático de la ultrasonografía y...
