ONLINE LECTURE SERIES CONTENT

Pigmenturia, or red-to-brown discolored urine, may be caused by hematuria, hemoglobinuria, or myoglobinuria. This talk will review less common causes of hematuria including bladder neoplasia, proximal urethral tears in stock-type horses, exercise-associated hematuria (without a cystolith), idiopathic renal hematuria of Arabian horses, and idiopathic cystitis.

The individual webinar titles of this webinar series are as follows:

• Why Renal Physiology should matter to the Critical Care Specialist

A working knowledge of renal physiology is necessary to understand how common treatments and medications for many disorders may result in unintended, adverse effects on renal function. Further, understanding renal physiology and pathophysiology allows a clinician to improve their diagnostic acumen, as well as to develop both a rational therapeutic approach and realistic expectation for outcome. This webinar will review age-related changes in renal function, renal hemodynamics, nephron segments, and how a concentrated or dilute urine is produced.

• Assessing Renal Function - what are our choices?

Our current tools to assess loss of renal function lack sensitivity. Thus, there is considerable interest in developing novel biomarkers, both in serum and urine, for earlier detection of acute kidney injury (AKI), with serum symmetric dimethylarginine concentration the most recent commercially available test. However, it is important not to overlook simple indicators of renal function, including urine production and changes in simple urinalysis parameters (specific gravity and reagent strip [dipstick] analysis), as they continue to provide valuable information about renal function. This webinar will review the strengths and limitations of current measures of renal function, present data on equine serum SDMA concentrations, and provide a practical approach to monitoring renal function in horses.

• Acute Kidney Injury in Horses - can we lessen the risk?

Acute kidney injury (AKI) is rarely a primary disease process. However, AKI can accompany many medical and surgical problems and be exacerbated by common treatments and medications. This webinar will review staging systems that have been developed for AKI as well as discuss early detection of AKI and common-sense strategies to lessen the risk of development of AKI when treating horses with various medical and surgical problems.

• Chronic Kidney Disease in Horses – Evaluation & Case Management

Chronic kidney disease (CKD) is fortunately a rare problem in horses, as compared to small animals and people. Unfortunately, most cases of equine CKD are only identified when the disease is advanced, causing lethargy and loss of condition. CKD is by nature a progressive disease process; however, earlier detection of CKD may allow intervention to slow progression and prolong a reasonable quality of life for months to years.
