Abstract

PURPOSE: Xanthogranulomatous pyelonephritis (XGP) represents an uncommon and challenging clinical scenario (1). XGP in a horseshoe kidney poses additional surgical complexity due to the anatomical anomaly (2). Robot-assisted radical nephrectomy (RARN) for XGP has been rarely reported (3), and single-port (SP) RARN via a retroperitoneal lower anterior approach (LAA) represents a recent innovation in the field (4). The aim of this video is to describe a case of SP RARN via LAA in a horseshoe kidney with XGP. MATERIALS AND METHODS: We report the case of a 51-year-old female (BMI 23 kg/m²) with XGP in a horseshoe kidney. A CT scan revealed severe left renal enlargement and hydroureteronephrosis, and a renal scan demonstrated
