Urinary Diversion for Vesicovaginal Fistula due to Carcinoma Cervix: Our Experience
摘要
Vesicovaginal Fistula (VVF) is a known complication of carcinoma cervix and can occur as a result of progressive disease, or as a complication of radiation, chemotherapy or surgery. Repair of VVF can be done only when it is a postoperative complication after an interval of about 8–12 weeks, and following concurrent chemoradiation if the patient is disease free for an interval of atleast 1 year. In most other cases, urinary diversion will be necessary to improve patient’s hygiene and general condition. Bricker type ileal conduit is the commonly performed urinary diversion surgery. Double barrel wet colostomy can be performed when the patient has a rectovaginal and vesicovaginal fistula.
PurposeTo study the challenges and outcomes of urinary diversion for VVF in patients of carcinoma cervix.
Material and MethodsAll the patients in whom urinary diversion was attempted between 01.05.2022 to 30.04.2025 were analyzed. The satisfaction rate among those who survived the procedure and completed the treatment of carcinoma cervix was determined to know who are most likely candidates who might benefit from the procedure.
ResultsUrinary diversion was attempted in 11 patients during the above period. The procedure had to be abandoned in 1 patient because of dense adhesions involving the ileum and vaginal vault. Bricker type ileal conduit was done in 9 patients. Double barrel wet colostomy was performed in 1 patient who had vesicovaginal and rectovaginal fistula. Two patients who underwent Bricker type ileal conduit died as a result of anastomotic leak.
ConclusionUrinary diversion does improve overall quality of life, though not survival in patients of carcinoma cervix with VVF. Obesity, diabetes, infection, prior radiation and chemotherapy are known causes of anastomotic leaks and such patients are less likely to benefit from the procedure.
