Laparoscopic Retrieval of Foreign Body in the Kidney: An Unusual Case Report and Literature Review

Renal foreign bodies are rare clinical entities that may result from iatrogenic injury, ingestion, or trauma. They often present with nonspecific symptoms, making diagnosis challenging.

We report the case of a 42-year-old woman with right flank pain of 2 months and a surgical history of Burch colposuspension and laparoscopic cholecystectomy. Computed tomography revealed a 6-cm linear hyperdense object, representing a needle-like foreign body that penetrated the posterior cortex of the right kidney. She underwent successful transperitoneal laparoscopic retrieval, with an uneventful postoperative course and complete recovery.

This case underscores the importance of maintaining a high index of suspicion and supports minimally invasive retrieval as a safe and effective approach, yielding favorable clinical outcomes.
