Stones in the urinary tract is one of the oldest diseases known to man. Today the spatio-temporal distribution of the disease is highly varied. The hot and dry subtropical regions (the so-called «stone belt») generally have the highest incidence. Moreover, cases of urinary calculi occur with unusual frequency during the summer («stone season») almost all over the world. Lastly, hot and dry weather, as well as large drops in air pressure, may favour the onset of renal colics in individuals predisposed towards it. Naturally identifying possible harmful factors in stone formation is still difficult, but climate is considered to play a non-negligible role. Excessive water loss through perspiration causing relative dehyaration is put forward as a common cause of urolithiasis ; this may be prevented simply and effectively by increasing fluid intake.
