These days, the most common problem that the urologists face is Urolithiasis and renal colic is the most highlighted one. Renal obstruction due to urolithiasis is the most frequent cause. This disease is widespread in our country and 12% of the Pakistani population has urolithiasis.

Resistivity Index

Doppler ultrasonography has been informed to be able to differentiate between obstructive and non-obstructive renal disease. It has also been suggested that severe urinary obstructions may cause decrease in blood flow and increase in vascular resistance. Doppler measurement of the resistive index can detect these changes. Doppler ultrasound can determine intrarenal resistivity index (RI) in renal stone obstruction. RIvalues provide reliable cutoff values to compare the normal and obstructed kidney resistivity index.
