Laparoscopic assisted mini-ECIRS for ectopic kidney lithiasis: A case report and literature review.

Introduction: Ectopic kidney is a rare anatomic variant with an incidence of about 1 in 900. Renal stones can pose a challenge when a standard approach is not possible. Laparoscopic-assisted endourologic procedure can be a feasible and safe choice.
Case Report and Literature Review: We present a case of 32 years old man with spastic quadriplegia, megacolon and pelvic kidney undergoing intervention of laparoscopic-assisted Mini ECIRS for staghorn stone of the left pelvic kidney. To the best of our knowledge, only 59 cases are reported in the literature concerning laparoscopically assisted encdourologic treatment which seems a feasible, safe and adaptable technique in selected complex cases.
Conclusion: Laparoscopic-assisted mini ECIRS is a viable option for the treatment of ectopic kidney stones. This technique should be considered when anatomical anomalies are encountered, to avoid puncture-related complications.
