Kidney Stones can be caused by anatomical abnormalities

Urinary tract stones are caused by several things, usually because the concentration of the concentrated urine resulting in deposition of crystals. These crystals will continue to grow with the passage of time. Other factors that facilitate the occurrence of stones are the anatomical abnormalities of the urinary tract so that the flow of urine becomes smooth. Which does not facilitate the smooth flow of crystal deposition?

An estimated number of people with stones in the community about 10-15%, but in countries such as the temperature and other tropical countries, the number of patients can reach 20%. Who have known risk factors include gender, age, race, occupation, geographic location, Body Mass Index and the weather.

One procedure acts to break up kidney stones is the shock wave (Extracorporeal Shock Wave Lithotripsy - ESWL). With ESWL of kidney stones and urinary tract stones can be broken down into fragments that can be refined so that the rock fragments out along with urine, so it should only be done if normal renal function.

ESWL is a device that is modern and safe and convenient procedures to cope with kidney stones without anesthesia and without surgical wound. This is the excess morbidity in addition to ESWL (morbidity) is low, easy to use and the patient can be ambulatory.

However, ESWL has shortcomings, which include stone-free rates are lower, especially for kidney stones with a large size compared with PCNL and open surgery. In addition to stone size, stone-free rate is influenced also by the hardness of stone, kidney function and kidney anatomical circumstances.
