[Usefulness of contrast enhanced ultrasound for evaluation of cystic renal masses.].

Objective: Contrast enhanced ultrasound(CE) consists of the intravenous injection of gasmicrobubbles and their detection within the kidney in differentphases. CE is more accurate than contrast enhancedtomography for detection of septa and wall thicknessvascularization in cystic renal lesions. The purposes ofthis study are to confirm the usefulness of this tool in thecharacterization of complex cystic renal masses and toassess its histological correlation.

Impact of Body Mass Index on Survival of Metastatic Renal Cancer.

Obesity has been established as a risk factor for renal cell carcinoma (RCC). Recently, studies have described obesity as a probable protecting factor in the metastatic stage of RCC. In this study, we assessed the relationship between body mass index (BMI) and overall survival in patients under systemic therapy.

[Gross hematuria and usefulness of urinary cytology: Experience at hematuria one stop clinic.].

Objective: To report the diagnostic accuracy and liability of the instrumentalized urine cytology in the preliminary study of monosyntomatic gross haematuria.

Methods: A retrospective, descriptive and analytic study of the patients that complained of macroscopic hematuria at the one-stop clinic between 2011 and 2018. The complementary tests requested were: kidney/bladder ultrasounds, urethrocystoscopy and urinary instrumentalized cytology.

[Metastasis of breast carcinoma in the ureter. Presentation of a clinical case.].

Objective: To assess the importance of long-term close follow-up in patients with breast carcinoma.

Materials And Methods: To present a case report.

Results: A case of a 55-year-old woman with history of lobular carcinoma of the breast is presented.

[Renal cell carcinoma metastases in rare anatomical locations: pituitary, thyroid and mammary glands. of our experience and report of three cases.].

Objective: Metastatic Renal Cell Carcinoma(RCC) may develop in different anatomical locationsand after a strict follow up within normal limits. We assessthe importance of close follow up in patients with historyof RCC through 3 clinical cases with unusual locations ofmetastatic RCC.

Methods: We present 3 cases of metastatic involvementof pituitary, thyroid and mammary glands.

[Renal angiomyolipoma in a patient with tuberous sclerosis. Case report.].

Objective: To assess the importance of management and close follow-up of patients with tuberous sclerosis that associate renal angiomyolipomas.

Methods: To report a case.

Results: A 55 years old men with tuberous sclerosis diagnosed in childhood and later finding of bilateral giant renal masses in imaging studies, with significant compromise of renal function.
