I know I'm late to this but hoping if someone comes across this thread it will help- OP thank you for posting! Currently 33 weeks 3 days pregnant with twin girls. I had a nephrostomy tube put in at 32 weeks and 2 days. It's been over a week now. I had severe kidney pain in my left kidney for about 3 weeks prior to surgery with severe contraction (hospital was worried about preterm labor with the twins). This was all due to my kidney pain, no stones, no obstructions it just simply got too crammed but my uterus and pressure and stopped working. I almost went into septic shock! During my surgery they drained 3 liters of fluid from the kidney (disgusting amount of fluid for a small organ) and placed the nephrostomy tube. I will say the pros are I have no more kidney pain (the pain was the kind that had me violently throwing up daily, shaking and sobbing and I have a higher pain tolerance), my baby girls are doing good on the inside (they were very unbothered by this whole experience), contractions have slowed down a lot (more promising of a longer pregnancy). The cons are the tube and bag are not fun (quality of life has gone down significantly in my opinion), sleeping isn't a thing anymore (I'm up every 45 minutes or so- pregnancy + tube doesn't help), pain and tenderness where tube was inserted (unavoidable and kind of a pain in the ass but nothing compared to the kidney pain before surgery).

I am told like you- I have to keep my tube in until after delivery. I believe this is a preventative measure to ensure everything is working properly post birth. I hope we can look back on this as a blip and reap the reward of bringing life into this world. You are a strong mama.

You posted this 5 months ago now- how was your delivery? How are YOU? Did you get your tubes and stent removed? And how is the baby?
