Unforeseen encounter: After liver abscess drainage, a foreign body was found in the renal pelvis.

Intrarenal foreign bodies are rare and could be iatrogenic through direct penetration, penetration through the gastrointestinal tract (GIT), or retrograde migration from the lower urinary tract. We present Intraoperatively incidental findings of an intrarenal foreign body during percutaneous nephrolithotomy (PCNL) with no previous urological intervention. However, there is a significant multiple percutaneous liver abscess drainage and endoscopic procedures. This case report of a pigtail thread rupture, likely resulting from recent hepatic abscess drainage. In conclusion, Intrarenal foreign bodies are rare, and there is no standard protocol for retrieving them. However, Treatment can be challenging by retrograde intrarenal surgery and PCNL.
