Nocturia

Section Editor: Kevin T. McVary, MD

In 2002, the International Continence Society (ICS) defined nocturia as “waking up at night at least once to void,” however, clinically relevant nocturia is generally accepted among urologists to indicate two or more voids that are preceded and followed by sleep. Neither definition accounts for the patient’s degree of bother from nocturia, though waking twice or more from sleep to void has been associated with impaired quality of life.

 

Upper Tract Urothelial Cancer

Section Editor: Seth P. Lerner, MD
Baylor College of Medicine
Upper tract urothelial carcinoma (UTUC) is cancer of the transitional urothelial cells that line the upper urothelial tract of the renal pelvis and ureter. This type of cancer accounts for between 5% and 10% of urothelial cancer cases. It’s the fourth most common cancer in men, but less common in women. In UTUC, the mean age of a patient diagnosed is 73 years. It can occur 3% of the time in both upper tracts (ureters or renal pelvis).
