Abstract

OBJECTIVE:To describe a novel surgical technique for the correction of recurrent obstructive urolithiasis in male goats.

STUDY DESIGN:Clinical case series.

ANIMALS:Castrated male goats (n = 4).

METHODS:Medical records of male goats having undergone vesicopreputial anastomosis (VPA) as a treatment for obstructive urolithiasis were reviewed for history, signalment, clinical signs, and intraoperative and postoperative complications. Long-term follow-up (≥12 months) was obtained by telephone interview with owners or by clinical examination.

RESULTS:All goats had undergone at least one surgical procedure (median, 2.5, range 2-4) to correct obstructive urolithiasis before undergoing VPA. Postoperative complications included premature removal of the tube from the bladder (1 goat), bacterial cystitis (2), and abscess formation (1). One goat suffered stricture of the anastomosis site 3 months following the original procedure and underwent a second VPA and 1 goat died 7 months after surgery due to severe, acute hydronephrosis and renal failure. Long-term survival ≥12 months was good with 3/4 goats (75%) or 3/5 VPA procedures (60%) having unobstructed urine flow at 12 months.

CONCLUSION:Vesicopreputial anastomosis is a feasible surgical procedure for the correction of recurrent obstructive urolithiasis in male goats and one that can result in a favorable clinical outcome. Further investigation in a larger population of goats is warranted for the evaluation of the suitability of VPA in male goats with obstructive urolithiasis.

Neoplasms in Domestic Ruminants and Swine: A Systematic Literature Review.
In all species, the most frequent neoplasms were squamous cell carcinomas in ruminants, while melanoma was the most frequent in swine.

Clinical Utility of Cytology from Preoperative Percutaneous Fine Needle Aspirates of Solitary Liver Masses in 220 Dogs: A Retrospective Study (2009-2019).
The agreement rate for correct cytologic diagnosis was 22.9% (49/220). Of the neoplastic masses 18.9% (35/185) were correctly diagnosed via cytology. The overall sensitivity was 60%, and the specificity was 68.6%. Neither institution, lesion size, cavitation, or needle gauge had an association with correct diagnosis. This study demonstrates that, although there is a low risk of complications following FNA of a hepatic mass, overall success rate for correct cytologic diagnosis based on FNA was low compared to histopathologic diagnosis.

Risk factors for unilateral cranial cruciate ligament rupture diagnosis and for clinical management in dogs under primary veterinary care in the UK.
After accounting for confounding factors, dogs aged 6 to less than 9 years, male neutered and female neutered dogs, insured dogs, and Rottweiler, Bichon Frise, and West Highland White terrier breeds, in particular, had increased odds of unilateral CCL rupture diagnosis. Insured dogs and dogs = 20 kg had increased odds of surgical management, while dogs = 9 years and dogs with one non-orthopaedic comorbidity at diagnosis with CCL rupture had reduced odds. These findings inform identification of at-risk dogs.

Neutering is not associated with early-onset urethral obstruction in cats.
Of 84 cats with signs of UO included in this study, 28.6% were classified as intact, 28.6% as prepubertal neutered, and 42.8% as post-pubertal neutered. Intact cats had a significantly earlier onset of UO compared with prepubertal and post-pubertal neutered cats, as seen by the age at obstruction (3.6 vs 5.7 and 5.5 years, respectively).

High-pressure injection of paint into the hand: A small injury with serious consequences.
High-pressure injection injury to the hand is a serious lesion threatening the limb. Several injected materials are involved, and paint is known to have the most serious consequences, with a high amputation rate. Early diagnosis and prompt treatment are two important prognostic factors for a better outcome.
