Abstract
Urethral stent placement is a minimally invasive interventional procedure commonly performed by specialists to alleviate urethral obstruction. However, the availability of urethral stents is limited by their high cost and the need for special equipment. The aim of this retrospective study was to describe the construction and placement of an inexpensive temporary urethral stent and to report on its outcome in managing dogs with naturally occurring urethral disease. Temporary stents were placed in the urethra of 17 dogs with malignant and nonmalignant urethral pathologies. The most common indication for temporary stent placement was urethral obstruction. In this population, urethral patency was restored in all dogs. The most frequently reported complication was urinary incontinence. To manage this complication, dogs were diapered. Temporary urethral stents served as a durable and inexpensive alternative to expanding metallic stents. Because temporary stents were constructed from readily available materials and inserted without special equipment, practitioners capable of catheterizing the urethra can insert them on demand.

The purpose of this report was to describe the construction and placement of a temporary urethral stent that was manufactured from materials typically available in most veterinary clinics, allowing stents to be inserted on demand as an outpatient procedure
Temporary urethral stents were constructed from materials typically available in most veterinary clinics and inserted without utilizing medical imaging, cystoscopy, or specialized training, allowing them to be placed on demand and as an outpatient procedure
Summary
Among the various indications for urinary stent placement, the need for immediate relief of urethral obstruction is perhaps the most pressing. Expandable metallic stents have been successfully placed inside the urethra of dogs with malignant and nonmalignant causes of obstruction [6,7,8,9,10,11]. Their high expense and the need for specialized training and equipment to insert them minimize availability and delay installation [12]. A second goal was to report on the indications and short-term outcomes for their use in dogs with naturally occurring urethral diseases
