in the group has focused on risk factors for

At RVC Small Animal Referrals, the
team offers general advice in relation to the
management of urinary tract conditions as
well as advanced diagnostic investigations.
These include renal biopsy for dogs and

Advanced techniques and technologies used in nephrology and urology
The RVC team has a particular interest in the management of stone disease affecting both the upper and lower urinary tract. We have
expertise in the evaluation of cats and dogs with nephroliths (stones in the kidney) and ureteroliths (stones in the ureter) as well as
those in the bladder (cystoliths).
Laser lithotripsy
RVC Small Animal Referrals is the only veterinary service in the UK offering laser lithotripsy treatment for urolithiasis. Laser energy
is provided within treatments via a fine silica quartz fibre. This can be advanced through the working channel of an endoscope to
provide targeted application of energy directly onto stones, causing fragmentation. It is particularly useful for managing stones causing
obstruction of the urethra in male dogs and cystoliths that cannot be dissolved in female dogs.
Fluoroscopy
Fluoroscopy is a specialist diagnostic imaging modality, enabling capture of real-time moving pictures of inside the body. It takes a
continuous series of low dose radiographs, which creates a live movie of the patient鈥檚 internal structures. Fluoroscopy is valuable for
many different sorts of cases by teams at RVC Small Animal Referrals, including checking for stones in the urinary tract. Such stones
may not be evaluated by ultrasound due to the pelvic bones and when fluoroscopy is used in conjunction with radiographic contrast
solutions it can help detect stones or structures that might not be visible with plain radiographs. Fluoroscopy and laser lithotripsy
equipment was funded by the Animal Care Trust, the RVC's registered charity.
Percutaneous cystolithotomy (minimally invasive cystotomy)
Percutaneous cystotomy enables uroliths to be removed from the bladder using a much smaller incision than a routine cystotomy
procedure. This minimally invasive technique minimises contamination of the abdominal cavity with urine, permits better visualisation
and, because the incision is smaller, there is less risk of future stone formation around suture material. When combined with cystoscopy,
a more thorough evaluation of the bladder and urethra is possible, to avoid leaving any stone material behind.
