The ultrasound study of ureteral jets in real-time or color echo-Doppler can be a diagnostic aid. Deyoe (1995) considered that the unilateral absence of a ure-teral jet demonstrates a complete obstruction, with 100% sensitivity and 91% specificity. Unfortunately, this measure is sometimes flawed. Wachsberg (1998) advised carrying out this test in the lateral decubitus position to prevent errors related to physiological mechanical compression. Burke and Washowich (1998) reported the complete absence of unilateral jet in asymptomatic pregnant women. The search for ureteral jets must therefore be interpreted cautiously, particularly in cases of partial obstruction (Biyani and Joyce 2002a; Evans and Wollin 2001).
