Summary

Retroperitoneoscopic pyeloplasty is a safe and effective treatment for ureteropelvic junction (UPJ) obstruction. This minimally invasive approach offers results comparable to open surgery.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Renal Surgery

Background:

  • Retroperitoneoscopy is an established surgical technique for renal procedures.
  • Ureteropelvic junction (UPJ) obstruction is a common cause of renal dysfunction.

Purpose of the Study:

  • To evaluate the efficacy and safety of retroperitoneoscopic pyeloplasty for UPJ obstruction.

Main Methods:

  • A retroperitoneoscopic pyeloplasty was performed on 24 patients (14 female, 10 male).
  • Standard retroperitoneoscopic techniques were employed with patients in a flank position.
  • Anderson-Hynes or Fenger pyeloplasty was utilized, with a double-J stent placed in all cases.

Main Results:

  • The average operative time was 189 minutes, with an average blood loss of 110 mL.

  • No intraoperative complications occurred; one patient required conversion to open surgery due to adhesions.
  • Postoperative complications were minimal, with a single instance of a urinoma. Follow-up showed no signs of obstruction.

    • Conclusions:

    • Retroperitoneoscopic pyeloplasty is a safe and effective treatment for UPJ obstruction.
    • Short-term outcomes are comparable to open pyeloplasty.
    • The procedure offers the advantage of a minimally invasive approach.
