Summary

Total hysterectomy for cervical cancer can cause urethral instability, particularly when extensive vaginal resection is performed. Urodynamic evaluation revealed significant issues in 18% of patients undergoing major vaginal resection.

Area of Science:

  • Urogynecology
  • Oncologic Surgery

Background:

  • Cervical cancer treatment often involves total hysterectomy.
  • Vaginal resection extent during hysterectomy may impact post-operative outcomes.
  • Urethral instability is a potential complication following pelvic surgeries.

Purpose of the Study:

  • To analyze the incidence of urethral instability after total hysterectomy for cervical cancer.
  • To determine the correlation between the extent of vaginal resection and urethral instability.
  • To evaluate urodynamic changes pre- and post-surgery.

Main Methods:

  • A cohort of 154 patients undergoing total hysterectomy for cervical cancer was studied.
  • Patients were divided into two groups based on vaginal resection extent (less than 2/3rds vs. 2/3rds or more).
  • Urodynamic evaluations were performed before surgery and at 1-year follow-up.

Main Results:

  • Persistent urethral instability was observed exclusively in the group with 2/3rds vaginal resection.
  • 18% of patients in the extensive resection group exhibited urethral instability at 1 year.
  • Significant pressure variations (>30 cm H2O) correlated with major urinary disorders.

Conclusions:

  • Extensive vaginal resection (≥2/3rds) during total hysterectomy for cervical cancer is associated with a higher incidence of urethral instability.
  • Urodynamic monitoring is crucial for assessing post-operative urethral function.
  • Minimizing vaginal resection may help prevent urethral instability complications.
