Summary
Radical vulvectomy can lead to incontinence, particularly when the urethra is involved in the excision. Preserving urethral anatomy is crucial for maintaining continence after vulvar cancer surgery.
Area of Science:
- Urology
- Gynecologic Oncology
- Female Pelvic Medicine
Background:
- Urinary incontinence is a known complication following radical vulvectomy.
- The precise relationship between surgical technique, urethral anatomy, and the development of incontinence remains undefined.
Purpose of the Study:
- To prospectively evaluate the impact of radical vulvectomy on urodynamic function and continence.
- To define the relationship between operative technique, urethral involvement, and postoperative incontinence.
Main Methods:
- Prospective evaluation of 21 patients undergoing radical vulvectomy for vulvar cancer.
- Preoperative and postoperative urodynamic studies were performed.
- Analysis of urethral length, pressure transmission, and continence status based on proximity of excision to the urethra.
Main Results:
- Six patients (28%) experienced a change in continence, including total, stress, and urge incontinence.
- All four patients with partial urethral excision developed incontinence.
- Significant decreases in functional and anatomical urethral length were observed in patients with urethral resection.
Conclusions:
- Radical vulvectomy alone does not appear to cause incontinence.
- Excision of a portion of the urethra significantly increases the risk of developing urinary incontinence.
- Preservation of urethral anatomy during vulvectomy is critical for maintaining continence.
