Purpose: To determine whether surgical procedures of the lower urinary tract in patients with uropathies affect evolution of the graft in renal transplantation.
Methods: 156 kidney transplantations were performed in 150 patients with end-stage renal failure due to urologic disorders. The patients were classified into three groups: A, patients who did not require surgery in the lower urinary tract; B, required surgery and preserved adequate bladder function, and C, required surgery due to vesical dysfunction.
Results: Graft survival rates at 1 year were 93.38% in group A, 95.45% in group B and 93% in group C. Rates at 5 years post-transplantation were 82.45, 79.85 and 86.58% for each group, respectively (not significant). Complications were vesicoureteral stenosis: 2 in group A, 3 in B and 1 in C; vesicoureteral reflux: 1 in group A, 1 in B and 10 in C; distal ureteral necrosis: 2 cases in group A, 2 in B and 1 in C; upper urinary tract infection: 12, 23.1 and 42.2% in each group, respectively.
Conclusion: Children with reconstructed urinary tract may be good candidates for kidney transplantation despite the higher frequency of urinary infections. Thus, careful and strict post-surgical urologic follow-up is mandatory.
