Lower Urinary Tract Dysfunction and Pediatric Renal Transplant.

OBJECTIVES: Lower urinary tract abnormalities have been considered to be contraindications for renal transplant. However, advancements in diagnosis and treatment in this area have allowed renal transplant as a treatment choice in selected cases. We evaluated clinical outcomes of pediatric renal transplant in patients with lower urinary tract dysfunction.

MATERIALS AND METHODS: We retrospectively evaluated data from 165 pediatric renal transplant patients, and data were compared between patients with and without lower urinary tract dysfunction. Patient demographics, cause of chronic renal failure, acute rejection episodes, and graft loss were included in our analyses.

RESULTS: Seventeen patients had lower urinary tract dysfunction, and the remaining 148 patients had functional lower urinary tracts. Patients with lower urinary tract dysfunction were younger than the other patient group at diagnosis of chronic renal failure. The mean follow-up after renal transplant in the 2 groups was similar. Differences with regard to donor type, immunosuppressive treatment, and acute rejection episodes were not significant between the 2 groups. Eight patients had lost their grafts during follow-up; however, only 1 of these patients was in the lower urinary tract dysfunction group. Graft loss rate was similar between the groups.

CONCLUSIONS: Pediatric patients with lower urinary tract dysfunction had similar graft outcomes versus other pediatric renal transplant patients. Careful evaluation and preparation of the lower urinary tract are important factors for renal transplant success.
