## TL;DR

This paper reports a rare complication where a double-J stent's loop became embedded in the kidney after a stone removal procedure, requiring surgery.

## Contribution

The paper presents the first documented case of proximal stent loop entrapment in the renal parenchyma after PCNL.

## Key findings

- A double-J stent's proximal loop became embedded in the kidney during PCNL.
- The complication required surgical intervention for resolution.

## Abstract

The double-J ureteral stent is a widely used device in urology. It is considered a revolutionary invention due to its significant clinical benefits. However, its increasing and sometimes prolonged use has been associated with specific complications. The use of a JJ stent is recognized as a standard drainage method following percutaneous nephrolithotomy (PCNL), and its proper placement is essential to prevent complications. We report the first documented case, to the best of our knowledge, in the literature of the proximal renal loop of a double-J stent embedded within the renal access tract during PCNL, which necessitated surgical intervention.
