Renal Calculus in an Ectopic Pelvic Kidney: A Case Report and Review of Literature

Abstract

Pelvic kidneys are anatomical abnormalities that occur when the kidney does not rise from the pelvis during embryogenesis. The majority of cases are asymptomatic, though they are associated with higher risks for traumatic injury, infections, renal calculi, and other urological issues.

Because of its advantages of flexion and deflection, retrograde intrarenal surgery (RIRS) employing flexible ureterorenoscopy (fURS) is an alternative treatment method for small- to medium-sized calculi in anatomically aberrant kidneys. Presented here is a case of a 43-year-old male with a renal stone in a pelvic left kidney with the ureter crossing the midlineand is located at the prevertebral region at the level of L4 to S1.
