Vagina: stricture

Contributor(s): David Godfrey

Introduction

  • There are few published reports of these conditions in cats.

Pathogenesis

Etiology

  • Unknown.

Predisposing factors

General

  • None known.

Specific

  • A variety of similar defects are possible. A persistent hymen would occur at the vestibulovaginal junction as a result of failure of the paramesonephric ducts to join the urogenital sinus. It might persist as an annular constriction or as a vertical band of tissue.
  • Failure of the two paramesonephric ducts to fuse would lead to a vertical septum in the vagina, a double vagina.
  • Vaginal atresia has been reported in a cat. This involves failure of part of the vagina to develop leading to a blind ending structure or to the reproductive tract fusing into the urinary tract.
  • Vulval strictures are possible.

Pathophysiology

  • Developmental defect.
  • Narrowing of the vagina may prevent natural mating or birth.
  • Abnormal anatomy might encourage an infectious vaginitis Vaginitis; this is a rare finding in cats, or might be involved with a urinary continence Urinary incontinence problem.
