Summary

Urinary diversion methods manage gynecologic cancer complications like obstruction or fistulas. Percutaneous nephrostomy (PCN) offers palliative relief and kidney function restoration, with improved survival rates in select patients.

Area of Science:

  • Oncology
  • Urology
  • Gynecology

Background:

  • Gynecologic malignancies can cause urinary tract obstruction or fistula formation.
  • Treatment strategies for urinary complications vary based on obstruction or fistula presence.

Purpose of the Study:

  • To review methods of urinary diversion in gynecologic cancer patients.
  • To discuss indications, outcomes, and considerations for palliative and permanent urinary diversion.

Main Methods:

  • Review of percutaneous nephrostomy (PCN) for palliative diversion.
  • Discussion of ureteral reimplantation and enterocytoplasty for radiation-induced stenosis.
  • Evaluation of ileal conduit for radiogenic fistula management.

Main Results:

  • PCN has a low complication rate and can precede permanent diversion.
  • Palliative diversion in tumor obstruction shows improved 6-month survival (approx. 70%).
  • Ileal conduit is effective for long-term urinary diversion in cases of large radiogenic fistulas.

Conclusions:

  • Urinary diversion decisions require consideration of individual factors, including quality of life.
  • Reimplantation or enterocytoplasty are preferred for radiation-induced ureteral stenosis.
  • Diversion is mandatory for fistula formation impacting quality of life, with ileal conduit as a viable option.
