Recurrent, nonobstructive, idiopathic feline lower urinary tract disease: an illustrative case report.

A three-year-old, spayed female domestic shorthair was evaluated because of recurrent hematuria, dysuria, and pollakiuria of one year's duration. With the exception of hematuria and proteinuria, results of other physical, clinicopathological, radiographic, and microbiologic evaluations were normal. Low concentrations of bovine herpesvirus-4 (BHV-4) antibodies (titer 1:40) were detected by an indirect fluorescent antibody test (IFAT). A diagnosis of nonobstructive, idiopathic feline lower urinary tract disease was established by exclusion of other known causes of hematuria and dysuria. Clinical signs resolved in approximately seven days without symptomatic therapy. During the next 69 months, the owners observed five episodes of self-limiting, gross hematuria and pollakiuria. Persistent low titers of BHV-4 antibodies were detected by the IFAT. This case typifies the clinicopathological, radiographic, and microbiologic findings and the natural course characteristics of many cases of nonobstructive, idiopathic feline lower urinary tract disease.
