To report the complications and factors affecting outcome for cats following placement of a subcutaneous ureteral bypass (SUB™). Materials and MethOds: In this retrospective study, complications, the presence of a urinary tract infection and survival time were recorded following subctutaneous ureteral bypass placement. Factors affecting survival time were assessed using a Kaplan Meier curve and log rank test. results: Ninety-five cats had 130 subcutaneous ureteral bypasses placed. Ten cats did not survive to discharge. Forty cats died or were euthanised after discharge (42%); the median survival time of these cats was 530 days (range 7 to 1915). Minor complications occurred in 18 cats (19%) and major complications occurred in 46 cats (48%), the majority of which were after hospital discharge. Twentyseven cats were diagnosed with a urinary tract infection (UTI) post-operatively. A significant association between long-term survival and creatinine at presentation was identified. The median survival time for cats presenting with creatinine concentration ≥440 μmol/L (International Renal Interest Society stage acute kidney injury (AKI) 4 and 5) was 530 days (95% CI 273-787 days), compared to a median survival time of 949 days (95% CI 655-1243 days; Log Rank P=0.024) for those cats presenting with creatinine <440 μmol/L (International Renal Interest Society stage AKI 1-3). clinical significance: In this population of cats, subcutaneous ureteral bypass placement was associated with an approximately 10% in-hospital mortality and a high complication rate. Most complications were manageable, resulting in an overall median survival time of over 2 years.

The objective of this study was to determine the outcome of cats with ureteric obstruction managed with double pigtail ureteric stents and to document the incidence of lower urinary tract signs at long-term follow-up. Data were obtained retrospectively from the medical records (2009-2012) of 26 cats that underwent ureteric stent placement. Owners were contacted for follow-up, and a quality of life questionnaire completed. Survival to discharge after stent placement was 85% (22/26). Prevalence of postoperative uroabdomen necessitating further surgery was 15% (4/26). Stents were replaced 4-28 months after the initial surgery in four cats because of migration, fracture, encrustation causing luminal obstruction or sterile cystitis, respectively. Nine cats were alive at follow-up, which was 3-28 months after the original surgery. Nine cats had azotaemic chronic kidney disease and nine had signs related to sterile cystitis; three of these cats were euthanased as a result of the severity of the signs. Preoperative serum creatinine of the survivors (9.4 mg/dl, n = 9) was not significantly different from that of the non-survivors (6.5 mg/dl, n = 13; P = 0.295). Quality of life was assigned a mean score of 8/10. Median survival of cats following discharge was 419 days (range 44-994 days). Signs consistent with sterile cystitis affected 35% of cats. It was concluded that ureteric stent placement in cats was associated with a 15% mortality rate before hospital discharge. Long-term management of ureteric stents is associated with a high rate of lower urinary tract signs.

OBJECTIVES To describe the presentation, diagnosis, cause, complications and outcome in 14 dogs that presented with a parotid sialocoele and that were treated by complete parotidectomy. MATERIAL AND METHODS Multi‐institutional retrospective study. RESULTS Each dog presented with a non‐painful, fluctuant, soft tissue mass over the lateral aspect of the face in the region of the parotid salivary gland. Diagnosis was made by sialoradiography (3/14), CT (3/14), ultrasound (11/14) and MRI (2/14). The cause of the sialocoele could be determined in 8 of 14 patients and included: foreign body (2/14), sialolithiasis (1/14), neoplasia (3/14), salivary gland lipomatosis (1/14) and trauma (1/14). Treatment incurred one anaesthetic complication (regurgitation) and seven postoperative surgical complications [self‐limiting seroma formation (2/14), haemorrhage (1/14), wound dehiscence (1/14), abscessation 7 months postoperatively (1/14) and facial nerve paralysis (2/14)]. Sialocoele did not recur in any dog during a median follow‐up time of 14 months. CLINICAL SIGNIFICANCE Parotidectomy has been considered a technically challenging procedure but can have a good success rate with long‐term resolution of the clinical symptoms. Intra‐ and postoperative complications are reasonably common.

OBJECTIVES Limited guidelines exist regarding the optimal treatment of traumatic canine elbow luxation, and there is a lack of information on long‐term functional outcome. Here we report reduction and stabilisation techniques for a series of traumatic elbow luxations and describe clinical outcome plus long‐term questionnaire‐based follow‐up. METHODS Retrospective review of canine traumatic elbow luxations (2006 to 2013) treated at five referral centres. Data recorded included signalment, luxation aetiology, time to reduction, reduction technique, surgical procedure, post‐reduction care and complications. Questionnaire follow‐up was attempted for all cases with owners completing the Canine Brief Pain Inventory. RESULTS Thirty‐seven dogs were included. The most frequent cause of luxation was road traffic accident (n=22). Twenty cases were treated surgically. Seven dogs suffered major postoperative complications: reluxation (n=6), infection requiring implant removal (n=1). Four of the six reluxations occurred in dogs that had other orthopaedic injuries. Twenty‐two owners completed the Canine Brief Pain Inventory questionnaire: there were 13 excellent, 6 very good, 1 good and 2 fair outcomes. Outcome was not associated with the reduction technique. CLINICAL SIGNIFICANCE Initial closed reduction, followed by surgical stabilisation if unsuccessful, results in good‐to‐excellent outcomes in the majority of traumatic canine elbow luxations. Reluxation was the most common major complication and there was a higher incidence of reluxation in patients with multiple orthopaedic injuries.

This report describes a cat that presented with abdominal pain and worsening azotaemia following unknown trauma. Further diagnostic investigations and surgery confirmed bilateral ureteral trauma. The cat was initially managed surgically by bilateral ureteroureterostomy over ureteral stents. The clinical signs and biochemical parameters rapidly resolved, but 2 months later the cat developed signs consistent with sterile cystitis that was unresponsive to medical management. Removal of the ureteral stents resulted in severe azotaemia as a result of stricture formation at the previous ureteral anastomosis site. The ureteral stents were initially replaced with soft stents, but subsequently cut short owing to the persistence of clinical signs of cystitis. Following shortening of the ureteral stents severe azotaemia was again observed. The resulting pelvic dilatation allowed for placement of bilateral subcutaneous ureteral bypass (SUB) systems, which resulted in alleviation of all clinical signs 12 months after SUB placement.

To report the mortality rate within a cohort of dogs undergoing cholecystectomy and investigate the impact of intra-operative hypotension on mortality. Materials and MethOds: Clinical records at five UK referral centres were reviewed for dogs undergoing cholecystectomy. Data collected included presenting signs, pre-operative blood test results, intra-operative data including frequency and duration of hypotension and the incidence and type of post-operative complications. results: Data from 119 dogs were included. Sixteen dogs (13%) died before discharge and by 28 days after surgery the total mortality was 19 dogs (17%). Hypotension lasting over 10 minutes during general anaesthesia occurred in 65 dogs (54.6%), with a mean ± sd duration of 36.1 ± 30.0 minutes. Intra-operative hypotension or the number of hypotensive episodes did not appear to be associated with in-hospital or 28-day mortality. American Society of Anaesthesiologists grade (of fitness for surgery) was significantly associated with both in-hospital and 28-day mortality on univariable analysis, as were post-operative hypoproteinaemia, ileus and pancreatitis. However on multivariable analysis, only ileus and pancreatitis were found to significantly impact mortality.

Objective: To report outcomes of dogs treated for lung lobe torsion (LLT) and to determine prognostic factors for survival.Study design: Retrospective multicenter study from four veterinary teaching hospitals.Animals: Dogs (n = 80) with LLT. Methods: Medical records were reviewed for clinical and histopathological findings. Long-term outcome was assessed with an owner questionnaire. Lung lobe torsion was classified as idiopathic or secondary on the basis of the etiology. Results: The most represented breeds were pugs (47.5%) and sighthounds (16.2%). The cause of the LLT was considered primary in 77%, secondary in 21%, and unknown in 2% of dogs. Postoperative complications were recorded in 14% of dogs. Overall, 95% of dogs survived to discharge, and median followup was 1095 days (range, 7-3809). Owners assessed outcomes and quality of life as excellent in 93% and 89% of dogs, respectively. Primary LLT was associated with a longer survival (median not reached in the study) compared with secondary LLT (921 days; range, 7-2073; P = .001). Conclusion:Overall long-term survival after lung lobectomy for LLT was excellent. Primary LLT was associated with longer survival compared with secondary LLT. Long-term owner evaluation of clinical outcome for dogs undergoing lung lobectomy for LLT was considered excellent. Clinical impact: Dogs with primary LLT undergoing lung lobectomy have a longer survival time compared with dogs with secondary LLT and have an excellent postoperative outcome.
