Resolution of urethral obstruction using temporary urethral stents in two female cats

Abstract

Case summary: The management of urethral obstructions is well documented in male cats but is less established for females. These cases describe two female cats that presented with non-dissolvable urocystoliths. Urocystoliths were removed by laser lithotripsy and basket retrieval. Following urolith removal, urethral obstruction occurred in both cats. Both cats were successfully managed using temporary urethral stents in lieu of indwelling urethral catheters permitting outpatient, spontaneous recovery of the urethra. Relevance and novel information: Use of temporary urethral stents has not been described in cats. These novel stents are constructed from materials available in most veterinary facilities, placed without advanced imaging and reside entirely within the urethra and vestibule. Temporary stents are used to bypass urethral disease, facilitating outpatient recovery, and are easily removed when no longer needed. For these reasons, temporary stents are a cost-efficient alternative to permanent stents or indwelling urinary catheters attached to closed urine-collection systems.
