AbstractIntroduction- Obstructive uropathy is one of the most commonly encountered problem in clinical practice. It is defined as structural impedance to the flow of urine anywhere along the urinary tract leading to pelvicalyceal dilatation. The resulting renal parenchymal damage caused by a virtue of the obstructive uropathy is collectively termed “obstructive nephropathy”.
Diagnostic Accuracy of Color Doppler in Obstructive Uropathy
Role of Color Doppler in Obstructive Uropathy
To determine the renal arterial hemodynamic changes induced by obstructive uropathy using Doppler ultrasonography.
To evaluate the diagnostic accuracy of renal venous doppler ultrasound in diagnosing obstructive uropathy
To evaluate the ability of this modality to differentiate obstructed from non-obstructed kidneys.
Materials and methods- The study was conducted in Department of Radio diagnosis of Index Medical College Hospital and Research Centre, Indore .
Our study include 100 patients out of these 50 were Obstructed Kidney and 50 were control
Results - PUJ and VUJ are most commonly involved in our study 30% and 30%respectively
On Color doppler Mean resistive index and mean venous Impedance value between Obstructed and control is statistically calculated 0.723 and 0.307. In our study mean arterial PSV in Obstructed and control group is calculate to be 31.14 and 17 respectively, and Mean venous PSV in obstructed and control group calculated to be 23.9 and 15.2 respectively
Conclusion- In conclusion from the study it is evident that the Arterial resistive index and venous impedance measurement by Doppler ultrasound has a high sensitivity and specificity in detecting acute renal colic.
