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 was associated with fewer postoperative lower urinary tract signs (p = .022) compared to OC.
• Incomplete urolith removal rates were not significantly different between PCCLm (11.4%) and OC (20%) groups.
• Anesthesia time was significantly shorter in PCCLm (median 97.5 min) vs. OC (120 min) (p < .001).
• Hospitalization time was significantly reduced in PCCLm, with 84.7% discharged same day vs. 0% in OC group (p < .001).
• Surgical site infection/inflammation (SSII) rates were not significantly different, though extension of PCCLm incision increased SSII risk (OR 18.76; p = .027).
• PCCLm had more intraoperative complications, but these were generally minor and did not affect outcomes.
• Dogs with urethral obstruction or large firm bladder were more likely to have residual uroliths postoperatively, especially in PCCLm group.
• PCCLm group had longer time to recurrence of urolith surgery and death, suggesting possible long-term benefits.
