Pelvic ectopic kidney with ureteropelvic junction obstruction: Surgical management and anatomical challenges: A case report

Ureteropelvic junction obstruction (UPJO) associated with a pelvic ectopic kidney is a rare condition that poses significant diagnostic and surgical challenges due to anatomical variations. We report the case of a 40-year-old male with no significant medical history, presenting with intermittent abdominal and pelvic pain evolving over one year with recent worsening. Imaging revealed a left pelvic ectopic kidney with marked hydronephrosis secondary to UPJO. The patient underwent open dismembered pyeloplasty according to the Anderson-Hynes technique with double J stent placement. The postoperative course was uneventful. UPJO in ectopic pelvic kidneys requires careful preoperative evaluation and individualized surgical planning. Despite the increasing use of minimally invasive techniques, open pyeloplasty remains a reliable and effective option in complex anatomical situations, providing satisfactory functional outcomes.
