Drain issue

im two weeks and three days post partial nephrectomy and I’m still draining a lot of fluid, anywhere from 40-65ml and based on tests of the fluid I am leaking urine.  It seems like a long time after surgery and a little internet research tells me this shouldn’t be happening.  My surgeon said it could be “weeks” but will eventually stop.  I’m wondering if anyone else had this experience.  Also worried about having to have more surgery of this doesn’t correct itself?!  Anyone have any experience here.  I know my collecting systems were involved which ups the likelihood that this wil be a problem.
