Hi Linda, I'm so sorry you're experiencing complications! I experienced complications after my emergency surgery for two obstructions in my small intestines about month after my lap-rny. My second surgery was an 'open.' Anyway, my kidneys kinda shut down, and I was holding about 30 lb of extra fluid. It was total misery! I can say I know how you feel. My kidney's didn't kick in and start really working until I was given HCTZ (a prescription water pill). It only took about 4 to 5 days of taking the medication, then the fluid was gone and my kidney's began functioning normally. From what my surgeon explained, sometimes your inner system goes into what can be described as shock, and shuts down to the minimal level of functioning, and it takes rest, healing, and sometimes help from medications to kick back in. Plus, I'm sure you've been pumped full of fluids----which makes it difficult. Anyway, maybe, this is happening to you also. I hope you'll be feeling better soon. If you want, please write when you get home. Sincerely, Lori Ann
