Clinical and radiographic findings compared with urodynamic findings in neutered female dogs with refractory urinary incontinence

Possible correlations were investigated between the clinical and urodynamic findings in 77 neutered female dogs with urinary incontinence refractory t o standard medical management. The clinical data used in the analysis were age, bodyweight, breed, the characteristics of the dribbling of urine and w hether it developed before or after neutering, the type of response to prev ious treatments, signs of polyuria/polydipsia, and the results of urinalysi s and culture. In 50 of the dogs, a standardised contrast radiographic exam ination was made to locate the neck of the bladder and to assess the morpho logy of the bladder. These findings were analysed for their correlation wit h the results of multichannel urethral pressure profilometry and diuresis c ysto-urethrometry. Logistic regression analysis revealed that neither the c linical nor the radiographic findings could predict any of the abnormal uro dynamic findings. Functional abnormalities of the bladder, such as a low co mpliance, detrusor instability, or a low bladder capacity may therefore be particularly difficult to detect in dogs with urinary incontinence.
