Abstract
When evaluating pediatric patients, Magnetic Resonance Urography (MRU) is a superior imaging modality that offers detailed anatomical imaging of the urinary tract and renal system. This study assessed the function of static MRU in pediatric hydronephrosis patients to identify the degree and cause of obstruction. Using ultrasonography (USG), pediatric patients with hydronephrosis were assessed for anatomical aberrations and levels of obstruction and the representation of congenital malformations. This was an observational study prospectively conducted at a tertiary‐level medical college and hospital over a period of 2 years. Thirty cases of pediatric patients with deranged renal function and hydronephrosis on ultrasonography were subsequently evaluated using heavy T2 weighted static MRU sequences on a Philips Achieva 1.5 T MRI system using a pediatric body coil. Data was acquired on a pretested proforma and quantitative data were processed to yield statistical Mean and SD values. 40 cases (69%) were males. The average age in this study was 4.4±4.3 years. The youngest patient was two months old and the oldest was 17 years. The most common diagnosis in this study was ureteropelvic junction (UPJ) obstruction, which was seen in more than half of patients (30 or 51.7%), followed by cases having ureterovesical junction (UVJ) obstruction (11 or 19%), VUR was seen in 9 (15.5%) cases and pyelonephritis in 7 (12.1%) and one patient (1.7%) had bilateral megaureter. When the value of the renal function obtained with DRS and CHOP‐fMRU methods were compared, no statistically significant differences were observed between these two methods. . The average value according to the DRS method was 46.9±18.9% (range 0‐87%) and according to CHOP‐fMRU, 47.6±21.5% (range 8.3‐100%) in cases of left kidney. The mean DRS value was 53.4±18.4% (range 13‐100%), while CHOP‐fMRU was 51.8±22.4 (range 0‐96.7%) in cases of right kidney. Static MR‐Urography is a superior imaging modality in pediatric patients with impaired renal function and hydronephrosis on USG. It is the best imaging modality for a thorough assessment of obstructing lesions in pediatric patients with hydronephrosis observed on USG for both congenital and acquired lesions. Lesions in the kidney were found to be the most common cause of obstructive uropathy, followed by those in the pelvis and ureters. More pediatric patients with congenital lesions than those with acquired lesions were seen in the presentation.
