Metástasis Pancreática Metacrónica de un Carcinoma de Células Renales. Reporte de un Caso

Int. j. morphol; 41 (5), 2023
El carcinoma de células renales (CCR) a nivel mundial presenta una incidencia de 431.288 casos anuales, causando 179.368 muertes en 2020. Sin embargo, a pesar de su incidencia, el desarrollo de metástasis pancreática (MP) de un RCC es un hecho inusual. El objetivo de este manuscrito fue reportar el ca...

Vertebral metastasis of renal carcinoma at diagnosis: mechanical and clinical evaluation: surgical management

Renal cell carcinoma accounts for 2-3% of all malignant neoplasms. Metastatic disease of the spine is common and 50% of bone metastases are already present at the time of primary diagnosis. Bone metastases from renal cell carcinoma are difficult to manage, especially ver...

Assessment of the complexity of renal tumors by nephrometry (R.E.N.A.L. score) with CT and MRI images versus 3D reconstruction model images

Role of preoperative MR volumetry in patients with renal cell carcinoma for prediction of postoperative renal function after radical nephrectomy and nephron sparing surgery

Int. braz. j. urol; 46 (2), 2020
ABSTRACT Purpose Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal func...

Diagnostic accuracy of contrast-enhanced ultrasound for detecting bland thrombus from inferior vena cava tumor thrombus in patients with renal cell carcinoma

Int. braz. j. urol; 46 (1), 2020
ABSTRACT Purpose: To evaluate the role of contrast-enhanced ultrasound (CEUS) in differentiating bland thrombus from tumor thrombus of the inferior vena cava (IVC) in patients with renal cell carcinoma (RCC). Materials and Methods: We retrospectively investigated 30 consecutive patients who underwent r...

Computed tomography imaging characteristics of clear cell papillary renal cell carcinoma

Int. braz. j. urol; 46 (1), 2020
ABSTRACT Purpose: Clear cell papillary (CCP) renal cell carcinoma (RCC) is a new subtype of RCC that was formally recognized by the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia in 2013. Subsequently, CCP RCC was added to the 2016 World Health Organization Cla...

Untargeted contrast-enhanced ultrasound versus contrast-enhanced computed tomography: a differential diagnostic performance (DDP) study for kidney lesions

Clinics; 75 (), 2020
OBJECTIVES: Histopathology is the 'gold standard' for diagnosing renal cell carcinoma but is limited by sample size. Contrast-enhanced ultrasound can differentiate malignant and benign lesions, but the Chinese guidelines on the management of renal cell carcinoma do not include this method. The purpose of...

A comparative study of ultrasound and cross-sectional imaging for detection of small renal masses: anatomic factors and radiologists experience

ABSTRACT Objective: To evaluate anatomic factors and radiologist's experience in the detection of solid renal masses on ultrasonography. Methods: We searched for solid renal masses diagnosed on cross-sectional imaging from 2007 to 2017 that also had previous ultrasonography from the past 6 months. The ...

Role of the three-dimensional printing technology in complex laparoscopic renal surgery: a renal tumor in a horseshoe kidney

Int. braz. j. urol; 45 (6), 2019
ABSTRACT Purpose: To report our initial experience using a patient-specific 3D-printed renal tumor model for the surgical planning of a complex heminephrectomy in a horseshoe kidney. Materials and Methods: We selected a clinical case for a complex laparoscopic surgery consisting in a 53 year-old male p...

Transesophageal echocardiography-guided thrombectomy of level iv renal cell carcinoma without cardiopulmonary bypass

Abstract Advanced renal cell carcinoma accompanied by tumor thrombus in the venous system is present in up to 10% of cases. Extension of tumor thrombus above the diaphragm or into the right atrium represents level IV disease. Level IV tumors are typically treated with sterno-laparotomy approach with or w...
