Sigmoid impaction secondary to urinary stones: case report and review of literature.

BACKGROUND

This is the first case report of a Miami pouch sigmoid fistula developing passage of urinary stones resulting in the presentation of constipation secondary to impaction.

CASE REPORT: A 49-year-old woman who developed a recurrence of invasive squamous cell cervical carcinoma 1 year after pelvis radiation. She then underwent anterior pelvic exenteration and creation of a Miami pouch. Approximately 14 years after the primary radiation therapy and 13 years after the creation of the exenterative procedure, the patient developed a Miami pouch sigmoid fistula. The decision was made at this time to repair the fistula and remove the urinary stones from the sigmoid colon. Postoperatively, the patient remained continent using intermittent catheterization of the pouch and there was no evidence of recurrence of the cancer.

CONCLUSION

Conservative management of urinary reservoir complications should always be considered before surgical intervention is attempted. When indicated, surgical management should not be delayed.
