Summary

Laparoscopic pyeloplasty provides effective pain relief for ureteropelvic junction obstruction (UPJO) with minimal invasiveness. Consider nephrectomy for patients with borderline renal function.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Ureteropelvic junction obstruction (UPJO) is a common cause of flank pain.
  • Laparoscopic pyeloplasty offers a minimally invasive alternative to open surgery.

Purpose of the Study:

  • To evaluate the initial experience and outcomes of laparoscopic pyeloplasty for UPJO in adult patients.
  • To assess the efficacy and safety of this minimally invasive approach.

Main Methods:

  • Retrospective review of 29 adult patients undergoing laparoscopic dismembered Hynes-Anderson pyeloplasty.
  • Patients were assessed for pain, imaging (ultrasound, IVP), and renal function (diuretic renogram) preoperatively and postoperatively.

Main Results:

  • Successful laparoscopic pyeloplasty in 28/29 patients, with one conversion to open surgery.

  • Mean operating time decreased with experience; mean blood loss was 50 cc, with no transfusions required.
  • Excellent symptomatic relief reported in 26 patients, but only 6 showed improved renal function on imaging at 6 months. Five patients with preoperative function ≤25% had worsened or negligible function post-procedure.

    • Conclusions:

    • Laparoscopic pyeloplasty is a safe and effective minimally invasive option for symptomatic relief in adult UPJO patients.
    • Nephrectomy may be a viable option for UPJO patients with borderline renal function (≤25%) and a healthy contralateral kidney.
