Laparoscopic transmesocolic pyelolithotomy and pyeloplasty in an ectopic pelvic kidney: Case report and review of literature

Abstract

Renal ectopia is a developmental anomaly with pelvic kidney being the commonest location (55%). The incidence of uretero-pelvis junction (UPJ) obstruction, nephrolithiasis, and reflux are higher in ectopic kidneys than their counterparts. We herein report a case of left ectopic pelvic kidney with large stone associated with UPJ narrowing managed successfully simultaneously with laparoscopic transmesocolic pyelolithotomy and pyeloplasty in a 45-year female. This is the largest stone reported in the literature in an ectopic pelvic kidney managed successfully with favorable outcome.
