The aim of this study was to compare uterine two-dimensional and Doppler ultra-sonographic parameters in queens suffering from pyometra from those in early pregnancy. Secondly, the effect of the presence of clinical signs of systemic illness on these parameters was also described. Fourteen post-oestrous queens, with uterine luminal content in the absence of embryos were included. According to their outcome (pyometra surgery or parturition), the queens were retrospectively assigned to one of the following groups: Pyometra (PYO; n = 7) or pregnant (PRG; n = 7). In all the queens, two-dimensional and Doppler ultrasound examinations of the uterus were performed. The presence or absence of clinical signs of systemic illness was recorded. The widest cross-sectional diameter (UD), uterine wall thickness (WT), uterine lumen contents (LC) and uterine artery resistance index (RI) were measured. Uterine horn diameter was higher in PYO group than in PRG group (p < 0.05), while WT (p > 0.1) and LC (p = 0.09) did not differ between groups. Values of RI for PYO and PRG groups were 0.61 ± 0.03 vs 0.53 ± 0.09 (p < 0.05), respectively. PYO cats suffering fromclinical signs of systemic illness showed larger UD than those without signs (p < 0.01). It is concluded that two-dimensional and Doppler ultrasound might be useful to distinguish queens suffering from pyometra from those in early pregnancy. Secondly, the clinical signs of systemic illness were associated with a larger UD.
