In some instances (<5%), non-muscle-invasive bladder cancer can progress to metastatic disease without any signs of bladder muscle or lympho-vascular invasion, a condition known as metastatic non-muscle-invasive bladder cancer. In this Perspective, the authors present the available literature on metastatic non-muscle-invasive bladder cancer, and discuss the potential aetiologies underlying this condition.

The circadian rhythm has a crucial role in regulating nocturia. In this Review, the authors discuss how the brain–kidney–bladder circadian axis can lead to nocturia, prompted by the rationale that understanding these disruptions can lead to developing effective treatments _targeting circadian rhythms.

In this Review, the authors provide an overview of molecular imaging in renal cell carcinoma, discussing the role of molecular imaging approaches in renal cell carcinoma diagnosis, treatment and response monitoring.

A common germline missense-encoding polymorphism in HSD3B1, called the adrenal-permissive allele, facilitates androgen synthesis from adrenal precursors via increased 3β-hydroxysteroid dehydrogenase 1 (3βHSD1). Here, the authors focus on mechanistic and clinical investigations of 3βHSD1 and the clinical consequences and potential utility of detecting adrenal-permissive allele inheritance.
