Severely painful spasm episodes after stent removal

Update 1 (3 days after stent removal): I managed to navigate the day with only paracetamol, Ibuprofen, and hot water bottle, which is a great improvement vs. having to continue taking the oral morphine. I stopped everything else including even the Tamsulosin & Oxybutynin. I had to drink crazy amounts of water (3 - 4L per day) and pee every 20 minutes. Only minor stinging now.

Update 2 (5 days after stent removal): First day to navigate without taking anything. I still have minor stinging but it's perfectly manageable. I noticed however that uring flow is a bit not too strong. I'm still confused and I don't know if there is something I should do or if this was normal part of the process.I am still trying to take a lot of water in (3 - 4L per day). All I'm hoping for is that there is no crazy blockage that my body got used to or anything.

Hi,

I had a mini PCNL on the left kidney last Thursday to remove a 2.5cm kidney stone. The surgeon put a stent in which was removed four days later (yesterday). Removal took seconds and I went home fine.

A few hours after returning home, I started getting awfully painful spasms like a renal colic on the left lower abdomen. It hurts like hell. I tried Paracetamol, Ibuprofen, Tamsulosin (flomax), Oxybutynin, hot water bottle on the abdomen. Nothing worked and I was rolling on the bed in agonizing pain. I remembered that they sent me home after the surgery with a bottle of oral morphine which I didn't even need to use in the first 4 days. I opened it and took 2.5ml, and within 20-25 minutes the pain subsided.

I relatively slept most of the night, but at 5AM it came back and woke me up. I tried the same things for about an hour and nothing worked and I was in torturing pain, so I took another dose of oral morphine, again it subsided.

I was fine for almost 12 hours until 5PM today, then it all came back, again, agonizing pain, nothing working, had to take a 3rd dose of oramorph, it went away.

It's almost 10PM now and I can feel it starting to come back again. The pain always starts light when I go to urinate, then it just keeps increasing more and more until everything in my abdomen spasms. I drink plenty of water as instructed (2-3 litres per day at least).

Is this a sign for something wrong with the surgery? Should I be worried and go back to hospital? Is this normal? When will this go away?

Any help is really appreciated.
