Urolithiasis - Definition

Ask a question


Urolithiasis is the presence of stones in the urinary tract. These stones can appear in different sizes and compositions; they are favored by dietary factors, insufficient fluid intake or urine stasis particularly in the context of anatomical anomalies. When a stone blocks a urinary tract, it causes severe pain called renal colic through tension on the urinary tract. The typical pain is severe and arrives suddenly, starting in the back and sides and moving to the genitals. After treatment of the pain, tests such as an ultrasound enable the detection of nephrolithiasis and the consideration of treatment. Stones can be eliminated suddenly by natural means or be dissolved by treatment with ultrasound, or in cases of large stones, they can be removed by surgery.
