• Discuss optimal evaluation methods for renal pelvic dilation (RPD) on postnatal imaging.  • Discuss the value of renal pelvis antero-posterior diameter (APD) in imaging evaluation of RPD. • Discuss factors influencing evaluation of RPD.  • Discuss the role of renal pelvis APD and alternative methods such as the hydronephrosis index (HI) in evaluation of RPD and in guiding management decisions such as performing pyeloplasty.  

Imaging findings in RPD Sample cases from US, IVP, MRU, fMRU Renal pelvis APD: is there a “cut off” between normal and obstructed? Factors affecting evaluation of RPD: Technique Timing of examination Hydration status Bladder filling Patient positioning Alternative methods of RPD evaluation Grading systems of fetal/neonatal hydronephrosis and RPD Postnatal imaging: Choice of imaging modality Three factors affecting choice of imaging modality: - Evaluation of morphology - Evaluation of function - Evaluation of reflux
