To the Editor:
Spinning is an aerobic activity performed on a stationary bicycle and carried out in groups in enclosed rooms, with instructors increasing and intensifying the workout by varying the resistance of the bike, altering the pace, or “jumping,” which is repetitive standing and sitting. This form of recreation is becoming extremely popular, and physicians should be aware of the possibility of gross hematuria in patients who participate in spinning.
A 58-year-old man was spinning five or six times per week. Gross hematuria was noted during routine examinations. Cystoscopy, retrograde ureteroscopy, intravenous pyelography, computed tomographic scanning, and cytologic studies failed to reveal the cause.
As spinning becomes more popular, hematuria will be noted in participants. Although it may be of a benign nature, this exercise could precipitate bleeding in a local lesion, so investigation is mandatory.
