It's not a glamorous title, but polishing your communication skills can help attract business from clients whose cats experience litter box problems.

Direct visualization of the lower urinary tract can be important for the diagnosis and treatment of many disease processes. Evaluation of the urinary bladder, ureters, and proximal urethra is possible via surgical exploration; however uroendoscopy is a minimally-invasive technique which allows assessment of the lower urinary and distal reproductive tract.

Recurrent and resistant urinary tract infections (UTIs) are among some of the most frustrating challenges veterinarians tackle in small animal practice.

There are many misconceptions regarding the significance of crystals found on routine urine sediment examination in dogs and cats. There is a large amount of information about the impact of diet, water intake, urine handling, breed, and many other possible contributing factors on the formation of crystals and stones.

Protein in the urine, particularly when it is of renal origin, can be an indicator of renal damage, and has been found to be associated with progression of renal disease. There are several reasons that protein can enter the urine, through a damaged glomerulus, through lack of reuptake by tubular epithelial cells, and through exudation into the tubular lumen.

One of the simplest and most cost effective diagnostic tools is at our disposal every day in practice, however we often overlook it and the large amount of data that it provides us. Urinalysis, including fresh sediment examination, can provide additional important information that complements and enhances the diagnostic information we gain from other diagnostic modalities such as serum chemistry, CBC, and the all-important physical examination.

Dogs and cats frequently present for signs related to the urinary tract. These signs may be due to inappropriate urination (house soiling or urinary incontinence) or may relate to the act of voiding itself.

Urinary incontinence is a common problem affecting up to 20% of spayed female dogs and 30% of those > 20 kg. In most of these patients it occurs within 3 years of spaying, although in many it may not become a major problem until later in life when it can be complicated by diseases that increase water intake and urine production.

Most cats with kidney uroliths have no clinical signs.

Study results indicate possible need for testing in these patients.

I had several banana split containers, so I brought the extras to the hospital to be used for urine collection.

In dogs, leptospirosis most commonly results in acute renal failure (ARF) with or without concurrent (or subsequent) hepatic disease. Although leptospirosis can cause ARF along with acute liver disease (or liver failure), ARF without liver disease has become the most common clinical presentation of the predominant serovars of leptospirosis affecting dogs in the US.

Diagnosis and management of the majority of cases are routine; however, treatment of refractory urinary incontinence cases are frustrating for both the veterinarian and owner. The diagnostic approach to dogs with refractory urinary incontinence should include a thorough history (drugs, age of onset, and timing during the day of incontinence), physical examination (including rectal and neurologic examination), serum biochemistry profile, urinalysis, urine culture, abdominal radiographs and ultrasonography.
