The results of this study suggest that the perioperative mortality rate of ureteral surgery is lower than that previously reported. Importantly, death was most commonly due to progressive renal failure and not surgical complications. Chronic lower urinary tract signs and urinary tract infection were common, particularly in cats with ureteral stents placed. The high incidence of reobstruction warrants appropriate client counseling and judicious follow up. Derangements of sodium and water balance are clinically significant consequences of kidney failure. During hemodialysis, sodium will equilibrate between the patient and the dialysate, providing an opportunity for changes to occur in the patient's plasma sodium concentration (PNa). It is not currently known how a dialysate-patient sodium gradient (D-PNa) may affect the PNa. The purpose of this study was to compare dialysate sodium concentration (DNa) to the pre-and post-dialysis sodium concentrations in dogs undergoing intermittent hemodialysis to identify a parameter that can be used to better prescribe DNa to correct alterations in plasma sodium.
