Diagnostic utility of ultrasonography for detection of the cause and location of ureteral obstruction in cats: 71 cases (2010-2016).

OBJECTIVE To assess the utility of ultrasonography to detect the cause and location of ureteral obstruction in cats and to identify factors associated with agreement between ultrasonographic and surgical findings. STUDY DESIGN Retrospective case series. ANIMALS 71 cats.

Perioperative morbidity and outcome of esophageal surgery in dogs and cats: 72 cases (1993-2013).

OBJECTIVE To evaluate perioperative morbidity and outcome in dogs and cats undergoing esophageal surgery. DESIGN Retrospective case series. ANIMALS 63 client-owned dogs and 9 client-owned cats.

Outcomes of ureteral surgery and ureteral stenting in cats: 117 cases (2006-2014).

Objective: To evaluate and compare outcomes in cats following ureteral surgery or ureteral stent placement.

Design: Retrospective case series.

Animals: 117 cats.

Perioperative morbidity and long-term outcome of unilateral nephrectomy in feline kidney donors: 141 cases (1998-2013).

OBJECTIVE To evaluate the outcome associated with unilateral nephrectomy in feline kidney donors. DESIGN Retrospective case series. ANIMALS 141 cats.

Diagnostic Accuracy of Ultrasound to Predict the Location of Solitary Hepatic Masses in Dogs.

Objective: To determine the sensitivity, specificity, and predictive value of ultrasonography for localizing hepatic masses in dogs and to identify patient factors associated with diagnostic accuracy.

Study Design: Retrospective cross-sectional study.

Animals: Client-owned dogs (n = 137).

Advances in Laparoscopic Surgery.

Recently, a new platform of abdominal access, called single-port surgery, has emerged in human and veterinary laparoscopy. The single-port platform enables all laparoscopic instruments, including the telescope, to pass individually through the same abdominal incision. Recently, there have been several published reports documenting the efficacy and safety of single-port procedures in veterinary patients.

End-to-end ureteral anastomosis and double-pigtail ureteral stent placement for treatment of iatrogenic ureteral trauma in two dogs.

Case Description: A 6-month-old spayed female Soft-Coated Wheaten Terrier and 8-month-old spayed female Shih Tzu were referred because of complications related to inadvertent ureteral ligation and transection during recent ovariohysterectomy.

Clinical Findings: The Soft-Coated Wheaten Terrier had a 2-day history of stranguria and polyuria that began after ovariohysterectomy. Initial examination findings were unremarkable with the exception of high rectal temperature.

Thoracoscopic-assisted pulmonary surgery for partial and complete lung lobectomy in dogs and cats: 11 cases (2008-2013).

Objective: To describe the use of thoracoscopic-assisted pulmonary surgery (TAPS) for partial and complete lung lobectomy in small animal patients and to evaluate short-term outcome.

Design: Retrospective case series.

Animals: 11 client-owned dogs and cats.

Retroperitoneal fibrosis in feline renal transplant recipients: 29 cases (1998-2011).

Objective: To evaluate features, treatment, and prognosis associated with retroperitoneal fibrosis that developed after renal transplantation in cats.

Design: Retrospective case series.

Animals: 29 cats.

Potentiation of regulatory volume decrease by a p2-like receptor and arachidonic acid in american alligator erythrocytes.

This study examined the role of a P2 receptor and arachidonic acid (AA) in regulatory volume decrease (RVD) by American alligator red blood cells (RBCs). Osmotic fragility was determined optically, mean cell volume was measured by electronic sizing, and changes in intracellular Ca(2+) concentration were visualized using fluorescence microscopy. Gadolinium (50 μM), hexokinase (2.

Regulatory volume response following hypotonic stress in Atlantic salmon erythrocytes.

The purpose of this study was to examine regulatory volume decrease (RVD) in Atlantic salmon red blood cells (RBCs). Osmotic fragility was determined optically, mean cell volume was measured electronically, and changes in intracellular Ca(2+) concentration were visualized using fluorescence microscopy and fluo-4-AM. Cells displayed an increase in osmotic fragility and an inhibition of volume recovery following hypotonic shock when they were exposed to a high taurine Ringer or when placed in a high K(+) medium.

Cardiac troponin-I concentrations in dogs with bradyarrhythmias before and after artificial pacing.

Objectives: To quantify cardiac troponin-I (cTnI) concentration in dogs with symptomatic bradyarrhythmias before and after artificial pacing and to correlate cTnI concentration with diagnosis, echocardiographic parameters, serology, and outcome.

Animals, Materials And Methods: Medical records from the University of Pennsylvania from 2006 to 2009 were reviewed, and 14 dogs with cTnI assay results before and after pacemaker were identified. The ECG diagnosis included complete atrioventricular block (AVB), sick sinus syndrome, 2nd degree AVB, and atrial standstill.
