Clinical Features of Endogenous Endophthalmitis Secondary to Minimally Invasive Upper Urinary Tract Calculus Removal

To evaluate endogenous endophthalmitis clinical features following minimally invasive removal of upper urinary tract calculi.

Medical records of twelve patients (17 eyes) with endogenous endophthalmitis secondary to minimally invasive upper urinary tract calculus removal were retrospectively reviewed.

Diabetes mellitus was found in 7 patients (58%). 10 patients (83%) suffered from fever. The stone extraction and ocular symptom onset interval ranged from 2 to 22 days. All eyes presented as vitritis and fluffy yellow-white retinal exudates. Hypopyon was only found in 3 eyes (18%). 5 patients (42%) were misdiagnosed as uveitis which led to mismanagement. Ocular fluids were culture positive for only C. albicans in 12 eyes (71%). 10 of 12 eyes (83%) with silicon oil tamponade obtained a final BCVA≥0.05.

C. albicans was the most common endogenous endophthalmitis pathogen after urinary calculus removal by minimally invasive surgery. Pars plana vitrectomy with silicon oil tamponade may be helpful to achieve a favorable visual outcome. Routine ophthalmologic evaluation by the uveitis or vitreoretinal specialist may be necessary within 2 weeks after the urological procedures.
