Urinary stones are known since the ancient times and represent one of the main issues in urological practice. The patients with small renal stones are generally asymptomatic or mildly symptomatic unless they pass to the ureters and cause renal colic. The asymptomatic course of the disease can lead to the formation of the bigger renal stones. The latter can lead to the reduction of the affected kidney function and repeated upper urinary tract infections. Therefore, a timely diagnosis and treatment of renal stones is very important to avoid further complications of the disease.
