Summary

Subcutaneous bypasses, including nephrovesical and nephrocutaneous types, offer a safe palliative option for ureteral obstruction in advanced cancer patients. This minimally invasive technique showed few complications during follow-up.

Comparison of adjustable male slings and artificial urinary sphincter in the treatment of male urinary incontinence: a retrospective analysis of patient selection and postoperative continence status.

World journal of urology·2018

Area of Science:

  • Urology
  • Oncology
  • Minimally Invasive Surgery

Background:

  • Ureteral obstruction is a common complication in patients with advanced pelvic malignancies.
  • Palliative treatment aims to relieve obstruction and improve quality of life.

Purpose of the Study:

  • To evaluate the effectiveness and safety of subcutaneous bypass for ureteral obstruction in patients with advanced malignancies.
  • To compare two minimally invasive techniques: nephrovesical and nephrocutaneous bypass.

Main Methods:

  • A specially designed composite implant (silicone-covered tube within an e-PTFE tube) was used.
  • The study included 14 patients undergoing either nephrovesical or nephrocutaneous bypass.
  • A mean follow-up period of 13.1 months was maintained.

Main Results:

  • Ten subcutaneous nephrovesical bypasses were inserted in 10 patients.
  • Eight nephrocutaneous bypasses were performed in 4 patients.
  • Complications were observed in 2 patients with nephrocutaneous bypass (one encrustation, one infection).

Conclusions:

  • Subcutaneous nephrovesical and nephrocutaneous bypasses are safe alternatives for palliative management.
  • These techniques effectively address ureteral obstruction caused by pelvic malignancy.
  • The minimally invasive approach offers a viable treatment option for this patient population.
