[Epidemiology, etiology and prevention of bladder cancer.].

Bladder cancer is the seventh most frequent cancer on male population and eleventh within the whole inhabitants. Differences in incidence and mortality between countries and regions exist. Those differences depend on variables including epidemiological data, social and cultural features and economics amongst the several populations that are exposed to different risk factors and treatment approaches.

American Confederation of Urology (CAU) experience in minimally invasive partial nephrectomy.

Purpose: To describe the perioperative and oncology outcomes in a series of laparoscopic or robotic partial nephrectomies (PN) for renal tumors treated in diverse institutions of Hispanic America from the beginning of their minimally invasive (MI) PN experience through December 2014.

Methods: Seventeen institutions participated in the CAU generated a MI PN database. We estimated proportions, medians, 95 % confidence intervals, Kaplan-Meier curves, multivariate logistic and Cox regression analyses.

Nephron-sparing surgery: our experience in open and laparoscopic approach in 254 cases.

Objectives: The majority of renal cell carcinomas are now incidentally detected as small renal masses in asymptomatic patients due to the widespread use of ultrasound and new improved noninvasive abdominal imaging modalities. Nephron-sparing surgery is the treatment of choice for patients with small renal masses in presence of normal contralateral kidney or in presence of an anatomic or functional solitary kidney. We reviewed retrospectively our experience in open and laparoscopic partial nephrectomy.
