[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.

[Scrotum-perineal granular cell tumor in pediatric age: A case report.].

Objective: Report a case of a scrotum-perinea lGranular Cell Tumor (GCT) in pediatric age.

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.
