Upper Tract Reconstruction & Kidney Care
- Most patients stay one night. A bladder catheter usually stays a few days.
- An internal stent protects the repair, usually for about 4 to 6 weeks, and is removed in the office.
- Bladder spasms, urgency, and blood in the urine are common while the stent is in.
- Shower after 48 hours. Walk daily. No heavy lifting until I clear you.
- Follow-up imaging confirms good drainage after the stent is out.
