Hi, thanks for using healthcare magic
means widenening of the renal calyces and renal pelvis
as a result of an obstruction that is usually distal (beyond) the renal pelvis.
The renal calyces are the parts of the kidneys that are involved in the collection of urine, they lead into the renal pelvis which would then lead into the ureter
.The ureter takes the urine to the bladder.
Heterogeneous collection means that when they looked at the mass/fluid that has collected near the left kidney- the parts of it were dissimilar.In a homogeneous collection or mass, all the parts of the area look basically the same.
This collection is said to be perinephric in the conclusion which means that it is outside the kidney. Because it is outside the kidney it may be obstructing the ureter resulting in the hydronephrosis.
No XXXXXXX vascularity noted means that there were no excess blood supply going to the collection that was seen.
As stated in the conclusion of the report, with the history of pain and purulent discharge in the urine, the result could be consistent with an abscess
collection in the area of the kidneys.
The definitive treatment of an abscess is incision and drainage
along with the use of antibiotic therapy.
Hope this helps and your daughter feels better soon,feel free to ask any additional questions
