Patients with advanced chronic kidney disease who progress to end-stage renal failure transition from urologic care to dialysis services at facilities including DaVita College Dialysis in the College Area. The Waring Road corridor in Allied Gardens provides residential proximity to the Zion campus for patients on active surveillance protocols who require frequent PSA monitoring and imaging follow-ups. His published work in The Journal of Urology includes research on anatrophic nephrolithotomy for staghorn calculi and colpocystourethropexy outcomes for recurrent stress urinary incontinence.
