Abstract:
Ureteric peristalsis is a key point for urinary progression. Its preoperative evaluation is important to assess indications for surgery. The study of the distal ureter is possible by means of ultrasound. Renal scintigraphy allows for a complete study of urinary progression along the ureter. A combined ultrasound and 99mTc-MAG3 preoperative work-up, has been performed in 32 urinary tracts (16 children ranging in age between 45 days and 11 years). Urinary progression occurs whenever peristaltic contraction makes the ureter lumen unpatent.
