Sorry for late response but I believe everything in your symptoms list (except slimy onion discharge) is completely normal post-ureteroscopy. I have had 4 and am going in for my 5th and 6th in the upcoming month so I am not a doctor, but I do have experience. You will probably continue to feel discomfort and pain while urinating as long as the stent is in. I feel more of a pulling or tugging on my ureter/kidney area, but I understand the pressure on teh kidney you are feeling. I always found that AFTER the stent is removed the healing truly begins. The stent is really just there to keep your ureter open for teh passage of urine since it's very swollen from being operated on. My full recovery time to get to minimal pain took about a month, which was 2 weeks after the stent was removed. I'm sure every case is different but I'd give it a month before getting too worried. I hope you are consulting your doctor on these matters as well, it's his job to guide you through this process. Also, the slimy onion like discharge could be an infection. You should probably go in for a urinalysis just to be safe bud, some antibiotics would clear that right up. I wish you well and hope that even though I was late this reaches you in good health and helps others who have this very common issue. God bless!
