As discussed in last month's Diagnote, the underlying causes of different types of uroliths vary. It follows that medical and/or surgical procedures designed to safely and effectively treat different types of uroliths also vary. The objective of the second part of this series is to provide an overview of risks and benefits associated with surgical and medical therapy of urolithiasis. Therapeutic caveats associated with treatment of specific types of uroliths will be the subject of next month's Diagnote.

Protocols have been developed to promote dissolution of canine and feline struvite uroliths, the dissolution of canine ammonium urate and cystine uroliths, and the prevention of all major types of canine and feline uroliths.

What do the words Fido, fidelity and confidence have in common? Can you find the root word in these terms? If you have decided the root word is "fid," you are correct. It is derived from the Latin term, "fidelitas." You Latin buffs may recall its meaning - "faithful."

Recently a colleague asked me for advice about stones in the urinary bladder of an 8-week-old female Shih Tzu. The owner, who had recently acquired the dog, was concerned about whether or not the uroliths were indicative of an inherited disorder.

The veterinarian's oath states in part, "Being admitted to the profession of veterinary medicine, I solemnly swear to use my scientific knowledge and skills for the... relief of animal suffering... Does this solemn promise encompass our being "Good Samaritans"? What principles are involved in being a Good Samaritan? What are Good Samaritan laws, and how do they affect each of us? To what extent should we contribute our resources in the role of being a Good Samaritan?

Recently a colleague asked us for advice about how to prevent recurrence of a urolith that contained a nucleus of 100 percent calcium oxalate (CaOx) and a distinct outer layer of 95 percent magnesium ammonium phosphate (MAP) and 5 percent calcium phosphate (Image 1 and Figure 2, p. 12S).
