Summary

Retrograde ureteroscopic endopyelotomy successfully treated ureteropelvic junction obstruction in a patient with an ectopic pelvic kidney. This minimally invasive approach avoided difficult percutaneous access, offering a viable treatment for complex cases.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrology

Background:

  • Congenital ureteropelvic junction obstruction can be challenging to treat, especially in cases of ectopic or malrotated kidneys.
  • Ectopic kidneys, particularly pelvic kidneys, present unique anatomical challenges for surgical intervention.
  • Percutaneous access may be difficult or contraindicated in patients with complex renal anatomy.

Observation:

  • A patient presented with an ectopic pelvic kidney experiencing ureteropelvic junction obstruction.
  • The obstruction was addressed using a retrograde ureteroscopic endopyelotomy technique.
  • Preoperative ureteral stent placement and angiography were utilized to guide the procedure.

Findings:

  • The ureteroscopic endopyelotomy was performed without the need for percutaneous access.

  • The patient experienced an uneventful recovery following the procedure.
  • Renal scintigraphy at 6 months postoperatively confirmed improved drainage from the affected collecting system.

    • Implications:

    • Retrograde ureteroscopic endopyelotomy is a feasible and effective treatment for ureteropelvic junction obstruction in patients with ectopic kidneys.
    • This technique circumvents the difficulties associated with percutaneous access in anatomically challenging kidneys.
    • The findings suggest ureteroscopic endopyelotomy is a well-suited option for managing ureteropelvic junction obstruction in ectopic renal moieties.
