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

Background: 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. Case Presentation: 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. Conclusion: 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.
