Abstract
A bladder mass with bilateral ureteral dilatation was observed in a French bulldog with polydipsia. Palliative surgery using the SUB system was performed to avoid urinary tract obstruction. NSAID therapy and urinary tract infection management were carried out without obstruction of the urinary tract / kidney. However, it became difficult for the dog to stand from the 246th day of disease and it died on the 264th day.
