Roberts SJ (1973)
Uterus 8 Days Post Partum 3.
The previously gravid horn has been opened up and washed out to highlight the involuting caruncles. Normal.
Roberts SJ (1973)
Uterus 14 Days Post Partum.
The surfaces of the caruncles have become necrotic in the normal process of involution.
Roberts SJ (1973)
Uterus 4 Weeks Post Partum.
Uterus of a ewe that delivered twins, which accounts for the symmetry of the horns. Involution is 90 per cent complete. Structure on the lower right is the bladder. Anestrous (inactive ovaries).

This postpartum uterus shows discoloration due to postmortem autolysis. Lighter colored, still enlarged, uterine blood vessels are also visible.
Smith MC (2006)
Hydrometra.
Accumulation of serous fluid in a nongravid uterus as a result of blockage. In this case an imperforate cervix. The wall of the uterus is thin.
Smith MC (2006)
Mucometra or Hydrometra.
Accumulation of sterile fluid in the uterine lumen can be associated with persistence of the corpus luteum. This may lead to anestrus and pseudopregnancy. The uterus may be extremely thin walled.
Mogheiseh A (2013)
Hydrometra Fluid.
Incision of the uterus reveals clear, sterile, watery fluid and a thin uterine wall. No placentation.

Mogheiseh A (2013)
Hydrometra vs Pregnancy vs Nonpregnancy.
