ABSTRACT
The purpose of this study was to evaluate and compare positive cystography techniques at 5%, 10%, and 20%, as well as three different double-contrast protocols for detecting radiolucent uroliths with a diameter of less than 3.0 mm in dogs. Six cadavers were used, one was selected at random to represent the negative control, and the others were submitted to urolith implantation in the bladder by urethral catheter. Three radiology professionals blindly accessed ventrodorsal and -lateral projections of each test. Contrast at 20% showed greater diagnostic sensitivity, but with greater difficulty identifying the number and size of the uroliths. Consequently, double-contrast techniques are better and should be used for diagnostic and therapeutic planning. Sensitivity and specificity tests demonstrated that positive 5% cystography and different concentrations of double contrast obtained better results in terms of sensitivity and specificity. However, due to the presence of a greater amount of artifacts in the 5% cystography, it is suggested that double contrast is used for this purpose, especially with the removal of contrast excess (protocol 2).

We describe a case of congenital duplication involving urogenital organs, pelvis and tail in a dog diagnosed by ultrasound scanning, retrograde urethrocystography, and excretory urography. Left nephrectomy, cystectomy, urethral resection, orchidectomy, penectomy, and caudectomy were the treatment options for this case. No spine or intestinal alteration was observed by radiography. After the surgery, the patient condition was assessed for one year. No significant changes were observed in ambulation or in laboratory test results during this period, including normal urination. The patient is currently 6 years old, and is in good condition and with quality of life.

ABSTRACT: Transplants for cats with naturally occurring renal disease have been introduced into clinical practice, but canine renal transplantation represents a greater challenge because of the lack of a balanced immunosuppressive protocol, difficulty in selecting compatible canine kidney donors, and absence of transplantation monitoring protocols. This and other important factors will be discussed in this review to help improve short- and long-term outcomes for renal transplantation in dogs.
RESUMO: O transplante renal em gatos com doença renal naturalmente adquirida está cada vez mais sendo introduzido na prática clínica. O transplante renal em cães, por sua vez, representa um desafio maior devido a falta da definição de um protocolo imunossupressor equilibrado, dificuldade na seleção de doadores compatíveis e ausência de protocolos de monitoramento de transplantes. Esses e outros fatores serão abordados nesta revisão afim de melhorar os resultados, tanto a curto quanto a longo prazo do transplante renal em cães.
