Hello, thank you for posting your query here.
First, debris in bladder and dye staying in bladder for a longtime means she has dysfunctional voiding, that is she does not pass urine well.
Some of the causes are
constipation, urinary infection, toilet training issues or habitual.
I would advise you to:
1. get a routine urine examination done, to check if there is urinary infection.
2. address constipation issues, if any. Lots of fluids, fibre like oats and bran, fruits and vegetables.
Lactulose syrup if she has hard stools
3. Make her do 'double voiding', that is after she urinates, take her to the bathroom again in ten minutes and ask her to pee. If any residual urine is there in the bladder, it will be emptied now.
Second, enlarged liver can occur with viral infections or
typhoid. Along with
jaundice it could be a marker of liver disease. If she does not have fever or jaundice, there is nothing to be concerned about a mild liver enlargement if her liver function tests are normal ( if not done, kindly do so) . You could repeat the
ultrasound in a month and take a call.
