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.
