🔍 Key Findings

• First reported case of total cystectomy and bilateral cutaneous ureterostomy in a cat using a modified Toyoda technique.
• Histologically complete tumor resection was achieved, with tumor-free ureter and urethral margins >20 mm.
• The modified Toyoda technique involved shaping the ureter into a fish-mouth aperture and anastomosing it to a rectangular skin defect for stomal formation.
• Incontinence was managed using a diaper changed every 6–8 hours, with no dermatological complications.
• Obstruction of the right ureter occurred 14 months post-op, associated with a subcutaneous nodule at the anastomosis site.
• Despite incontinence, owner satisfaction and perceived quality of life were high, with the cat living ~16 months post-op.
• The stents were removed on days 7 (left) and 28 (right) postoperatively, with initial patency maintained until 14 months.
• This surgical approach may offer palliative or curative benefit for feline trigonal TCC where partial cystectomy is not feasible.

🔍 Key Findings

• CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
• Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
• Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
• CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
• 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
• Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
• Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
• Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.

🔍 Key Findings

• Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
• All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
• Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
• Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
• Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
• Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
• Use of locking screws improved reduction fidelity, particularly across a broad plate span.
• 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

🔍 Key Findings

• Ectopic ureters in cats are rare, but most are extramural and bilateral.
• Surgical techniques used included ureteroneocystostomy (UNC), neoureterostomy (NU), nephroureterectomy, and cystoscopic laser ablation (CLA).
• All cats showed improvement in urinary continence postoperatively, with 11/12 achieving complete resolution.
• Major complications were rare; one cat developed uroabdomen requiring revision surgery.
• Diagnostic imaging was effective, with abdominal ultrasound diagnosing 8/10 and CT 3/3 cases.
• Short- and long-term complications included urethral spasms, UTIs, stranguria, and rectal prolapse; all were manageable.
• CLA was successful in 2 cats and is noted as a first-time described technique in feline ectopic ureter cases.
• Median postoperative follow-up was 340 days, supporting good long-term outcomes.

🔍 Key Findings

• Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
• Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
• All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
• Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
• Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
• No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
• Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
• TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.

🔍 Key Findings

• Adding a single locking throw significantly increased holding security for specific knots, including the surgeon's throw (p = .0001) and square throw (p = .0002).
• For the Miller's throw (p = .166) and strangle throw (p = .808), no significant improvement was observed with a locking throw.
• After locking throw addition, all five knots leaked at similar pressures (p = .5233), and these pressures exceeded physiologic arterial pressures.
• Surgeon's throw without a locking throw had the lowest leak pressure (62.5 ± 46.2 mm Hg), below physiologic arterial values.
• The square throw without locking also leaked below physiologic pressures (148.7 ± 109.4 mm Hg), though it outperformed the surgeon's throw.
• Miller’s and strangle throws performed significantly better than square or surgeon’s throws without locking, achieving leak pressures >200 mm Hg.
• All knots used 2-0 polyglyconate monofilament (Maxon); no comparisons across suture types or sizes were performed.
• Authors concluded that correct tensioning and locking throw addition are key to safe vascular ligation. Miller’s, strangle, or slip knots are preferred for challenging surgical fields.

🔍 Key Findings

• Crescent guide use resulted in significantly less medial cortical damage (mean 3.8 mm²) than the radial saw guide (35.7 mm²) and standard jig (51.3 mm²) in bone models.
• No significant difference in osteotomy accuracy (distance of eccentricity, coronal or axial angulation) among crescent guide, radial guide, or standard jig in either bone models or cadavers.
• Device application time was shortest with the crescent guide and longest for the radial saw guide.
• Osteotomy time was fastest with the crescent guide compared to the radial saw guide (P = .015).
• Participants rated the crescent guide easier to apply than both the radial saw guide (P < .005) and the standard jig (P = .015).
• 5 of 6 novice participants preferred the crescent guide over the other devices for performing TPLO.
• Subjective ease of osteotomy performance was higher with the crescent guide vs. radial guide (P < .001).
• Crescent guide does not assist in fragment stabilization or plateau rotation unlike a standard TPLO jig.

🔍 Key Findings

• Open face version was significantly greater than truncated face version by 14°–22° (p <.001).
• Open face version increased linearly with inclination and pelvic extension, while truncated face version remained largely stable.
• Truncated face version is an unreliable surrogate for open face version.
• Accurate interpretation of cup version should include both truncated face version and inclination.
• Canine 3D pelvic model and CT-based simulation used for all measurements.

🔍 Key Findings

• Postoperative complications occurred in 20% of stifles, including 7.5% minor, 10.3% surgical, and 3.4% medical complications.
• The PROSPECT machine-learning model achieved high predictive accuracy: 92.3% for surgical complications, 91.9% for minor, and 94.3% for medical.
• Top predictive features included surgical technique, implant type, patient age, and surgeon identity.
• Surgeon-specific variables influenced predictions, indicating operator experience and technique matter.
• Engineered interaction features (e.g., breed × implant) were more predictive than raw clinical data alone.
• Rottweiler, intact male status, and higher bodyweight were associated with increased complication risk; Labradors had decreased risk.
• Model calibration was strong, especially for high and low probability predictions; midrange predictions were less reliable.
• The model supports individualized, probabilistic risk assessment, which could inform client counseling and tailored postoperative care.

🔍 Key Findings

• Complication rate for subdermal plexus flaps (SPFs) in dogs was 53.6%.
• Skin staples had a numerically higher complication rate (72.2%) than sutures (49.3%), but not statistically significant due to small sample size.
• Most common complication was wound dehiscence (35%), followed by seroma (14%) and wound discharge (14%).
• Increased body weight was significantly associated with higher complication risk (OR = 1.056 per kg; p = .029).
• Advancement flaps were associated with a lower incidence of complications on univariable analysis (p < .001).
• Head region flap closures had fewer complications, while proximal pelvic limb closures had the highest complication rate.
• Age was a risk factor—each additional year increased odds of complications (OR = 1.019; p = .004).
• Closure technique did not significantly influence complication severity, though staple use was numerically worse.
