[Fistula surgery]

Area of Science:

• Urology
• Surgical Oncology

Background:

• Vesicovaginal fistulas are infrequent in Western countries, often resulting from hysterectomy in Germany.
• Urorectal fistulas increase in incidence and complexity with repeated prostate cancer treatments.
• There is no established consensus on the optimal surgical approach for these complex fistulas.

Purpose of the Study:

• To review the treatment approaches and outcomes for vesicovaginal and urorectal fistulas.
• To highlight the challenges and success rates associated with surgical repair, particularly in specific patient populations.

Main Methods:

• The study synthesizes information on surgical treatment strategies, including transvaginal and transabdominal approaches.
• It considers conservative management options like temporary catheter drainage for early-stage fistulas.

Main Results:

• Surgical treatment generally achieves high permanent fistula closure rates for both vesicovaginal and urorectal fistulas.
• Fistula repair in patients with a history of radiation therapy demonstrates significantly lower success rates.
• Spontaneous closure is not expected for radiogenic fistulas.

Conclusions:

• Surgical repair is effective for vesicovaginal and urorectal fistulas, but patient-specific factors and prior treatments influence outcomes.
• Early diagnosis may allow for conservative management, though success is limited in irradiated cases.
