Summary

This study tests whether putting a drug called aminophylline into the bladder before placing a ureteral stent helps doctors get the stent past a blocking stone more easily. The trial involves 72 adults with sudden kidney failure from stones in a single working kidney. Half get the drug, half get a placebo, and the main goal is to see if the drug helps avoid a more invasive drainage procedure.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Aminophylline
What this could lead to: If it works, this could make emergency stent placement easier and reduce the need for a more invasive kidney drainage procedure.
What could go wrong: This is a small Phase 2 trial with only 72 participants, so results may not apply broadly. The drug may not improve success rates and could cause side effects like allergic reactions.
