Hello madam, thanks for asking your question on this forum. We are here to help you, so dont worry about not being able to pay! What you describe suggests some kind of block at the level of mid/ lower ureter
. The urine produced in the kidney
comes down via the ureter (tubes connecting kidneys to bladder) to the bladder. If there is some kind of partial block in the ureter there will be back pressure on the kidney and the kidney pelvis and proximal part of ureter appear full/ dilated. The heterogenous opacification in the renal pelvis
(part of kidney where the urine collects before draining into ureter) could be due to infection/ blood clot/ growth etc. This needs to be looked into by a urologist
. Good luck.
