Thanks for your query.Based on the facts that you have posted it appears that Double J stent
has been put in your ureter
to the Ureter while doing Hysterectomy
Do not worry injured ureter is bound to heal within six week time .
and discomfort is bound to be there due to back flow of urine from bladder to kidney
through the stent.
As regards other symptoms like itching in pals is not due ti=o stent but may be due to some other rason. Pleas consult your treating Dr and take any Vitamin Supplements,
