Female urethral obstruction after Marshall-Marchetti-Krantz operation

Area of Science:

• Urology
• Female Pelvic Medicine and Reconstructive Surgery

Background:

• Iatrogenic urethral obstruction is a potential complication following anti-incontinence procedures like the Marshall-Marchetti-Krantz operation.
• This condition can significantly impact a woman's quality of life, causing voiding dysfunction and urinary retention.

Purpose of the Study:

• To investigate the efficacy of a specific surgical approach for treating female urethral obstruction post-Marshall-Marchetti-Krantz.
• To analyze the urodynamic findings, clinical outcomes, and long-term results of the intervention.

Main Methods:

• Retrospective review of 13 neurologically normal women diagnosed with urethral obstruction after Marshall-Marchetti-Krantz surgery.
• Treatment involved a transvaginal procedure: complete urethrolysis followed by needle urethrovesical resuspension.
• Urodynamic testing was used for diagnosis and post-treatment assessment.

Main Results:

• Twelve out of 13 patients (92%) experienced complete symptom resolution and a return to normal voiding patterns.
• Postoperative urine residuals were reduced to less than 50 cc in the successfully treated patients.
• One patient required intermittent catheterization despite being urodynamically unobstructed.

Conclusions:

• Transvaginal urethrolysis with needle urethrovesical resuspension is a highly effective treatment for iatrogenic female urethral obstruction.
• This minimally invasive approach offers significant improvement in voiding function and quality of life for affected women.
• Understanding the pathophysiology and employing timely diagnosis are crucial for managing this complication.
