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.

Assessment of Contrast-Enhanced Ultrasound (CEUS) and Computed Tomography (CT) diagnostic accuracy in the evaluation of challenging cystic renal masses.

Purpose: To assess the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) and computed tomography (CT) within Bosniak IIF/III categories.

Methods: After cystic renal mass diagnosis by contrast-enhanced CT, all patients with Bosniak score ≥ II also underwent CEUS between March 2017 and March 2019. Their exams were retrospectively analyzed.

Testicular seminoma with pagetoid spread into the vas deferens: A rare histopathological presentation.

Testicular cancer, in particular testicular germ cell tumours, is the most common malignancy in young adult men. Defining prognosis and the best therapeutic strategy is challenging since accurate staging could be controversial. We report an unusual case of seminoma with pagetoid spread into the rete testis and, unexpectedly, also within the epithelium of the vas deferens, up to the margin of excision of the spermatic cord.

Spontaneous urinary bladder perforation: An unusual presentation of well-differentiated papillary peritoneum mesothelioma.

Introduction: Well-differentiated papillary mesothelioma (WDPM) is a very rare neoplasm. Most of WDPM are asymptomatic and are often incidentally detected during surgery. This report describes a case of WDPM of the peritoneum unexpectedly diagnosed in a male with a spontaneous intraperitoneal bladder rupture.

COVID-19 pandemic and uro-oncology follow-up: A "virtual" multidisciplinary team strategy and patients' satisfaction assessment.

COVID-19 pandemic strongly modified the organizations of our clinical practice. Strict containment measures have been adopted to limit the disease diffusion. In particular, hospital face-to-face post discharge and follow up visits have been reduced.

Incidental finding of paratesticular aggressive angiomyxoma in a 72-year-old monorchid male.

Aggressive angiomyxoma is an uncommon mesenchymal neoplasm. It arises from soft tissue of pelvis and perineum in fertile females, occurring very rarely in males. Its name emphasizes the common local recurrence and infiltrative tendency, but usually it does not metastasize.

Bilateral hydroureteronephrosis with renal failure caused by malacoplakia.

Introduction: Malacoplakia is a rare chronic inflammatory disease that most commonly involves the genitourinary tract with a wide spectrum of clinical presentation.

Case Description: A 65-year-old woman presented with obstructive nephropathy with bilateral hydroureteronephrosis. Bilateral nephrostomy-tube placement saw an improvement in her renal function.
