Can we renounce performing the intravenous urography in the preoperative evaluation for ESWL treatment?
OBJECTIVE
Our aim was to perform a comparative study between IVP (Intra Venous Pyelography) and Doppler US (Ultras Sound) in assessing the normal renal function. The US assessment of the normal renal function consisted in the evaluation of ureteral flux.


METHODS
The group of patients consisted in 79 patients with small size urinary stones (5-12 mm). Among them, 58 patients had pelvic stones and 21 patients had ureteral stones. The ultrasound system used in our study was a B&K Medical Panther 2002 equipped with a 3.5 MHz transducer.


RESULTS
The sensibility in detecting ureteral flux in patients with pelvic stones and normal IVP was 100%. The sensibility in detecting uretheral flux in ureteral stones with IVP aspect of hydronephrosis was 65%.


CONCLUSIONS
In cases of normal aspect of IVP the presence of uretheral flux assessed by ultrasound could substitute the IVP in the preoperative evaluation for ESWL treatment. In cases of hydronephrotic aspect of IVP, the concordance between results based on IVP and those based on Doppler US in good enough for proposing the Doppler US evaluation of renal function in obstructive stones as a new diagnostic imaging modality. Doppler US could be the method of choice for renal function pre ESWL evaluation mainly for patients with known intolerance to contrast media.
