Patient and Context Factors in the Adoption of Active Surveillance for Low-Risk Prostate Cancer.

Importance: Although active surveillance for patients with low-risk prostate cancer (LRPC) has been recommended for years, its adoption at the population level is often limited.

Objective: To make active surveillance available for patients with LRPC using a research framework and to compare patient characteristics and clinical outcomes between those who receive active surveillance vs radical treatments at diagnosis.

Design, Setting, And Participants: This population-based, prospective cohort study was designed by a large multidisciplinary group of specialists and patients' representatives.

Primary small-cell neuroendocrine carcinoma of the bladder: Case report and literature review.

Background: Neuroendocrine tumours (NET) are extremely rare and aggressive. Although they commonly affect intestine, many organs may be involved such as pancreas, lung or urinary tract. Bladder is rarely involved.

Advanced chondrosarcoma of the pelvis: A rare case of urinary obstruction.

Chondrosarcoma is the second most common malignant tumor of the bone with an incidence of 1 in 200.000 per year. Axial skeleton is frequently involved showing poorer oncological outcomes than appendicular one: human pelvis is a site predilection.

Surgical repair of abdominal aortic or iliac aneurysms associated with treatment of urological neoplasias.

Safe surgical repair of an abdominal aortic aneurysm in conjunction both with nephrectomy (for monolateral or bilateral kidney carcinoma) or with radical cystectomy and orthotopic urinary diversion (for bladder carcinoma) can be performed. These combined surgical procedures can be performed without morbidity due to excessive blood loss, increased operative time or vascular graft infection. A nephrectomy associated with abdominal aortic aneurysm repair can be performed both by a median single surgical approach or by a double one during the same intervention.
