Adair et al: Retrospective comparison of modified percutaneous cystolithotomy (PCCLm) and traditional open cystotomy (OC) in dogs: 218 cases (2010–2019)
Veterinary Surgery 7, 2023

🔍 Key Findings

  • PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
  • Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
  • PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
  • Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
  • Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
  • PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
  • Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
  • Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.
