OBJECTIVES: Lower urinary tract dysfunction can lead to chronic kidney disease, which, despite surgical intervention, will progress to end-stage renal disease, requiring dialysis. Urologic pathology may damage a transplanted kidney, limiting patient and graft survival. Although smaller studies have suggested that urinary tract dysfunction does not affect graft or patient survival, this is not universally accepted. Northern Ireland has historically had the highest incidence of neural tube defects in Europe, giving rich local experience in caring for patients with lower urinary tract dysfunction. Here, we analyzed outcomes of renal transplant recipients with lower urinary tract dysfunction versus control recipients.

MATERIALS AND METHODS: We identified 3 groups of kidney transplant recipients treated between 2001 and 2010; those in group 1 had end-stage renal disease due to lower urinary tract dysfunction with prior intervention (urologic surgery, long-term catheter, or intermittent self-catheterization), group 2 had end-stage renal disease secondary to lower urinary tract dysfunction without intervention, and group 3 had end-stage renal disease due to polycystic kidney disease (chosen as a relatively healthy control cohort without comorbid burden of other causes of end-stage renal disease such as diabetes). The primary outcome measured, graft survival, was death censored, with graft loss defined as requirement for renal replacement therapy or retransplant. Secondary outcomes included patient survival and graft function.

RESULTS: In 150 study patients (16 patients in group 1, 64 in group 2, and 70 in group 3), 5-year death-censored graft survival was 93.75%, 90.6%, and 92.9%, respectively, with no significant differences in graft failure among groups (Cox proportional hazards model). Five-year patient survival was 100%, 100%, and 94.3%, respectively.

CONCLUSIONS: Individuals with a history of lower urinary tract dysfunction had graft and patient survival rates similar to the control group. When appropriately treated, lower urinary tract dysfunction is not a barrier to successful renal transplant.
