Interventions for impaired bladders in paediatric renal transplant recipients with lower urinary tract dysfunction

Dysfunctional bladders in paediatric patients were thought to be a contraindication for renal transplantation, but advances in surgical techniques have meant that surgical correction can allow safe transplantation. This study compares the outcomes of renal transplantation for different interventions, and the timing of such interventions, in relation to transplantation. We identified all paediatric renal transplant recipients with LUTD that received intervention for their impaired bladders at two hospitals between 2002 and 2010. Outcome measures included patient and graft survival, perioperative complications, UTI incidence, acute rejection episodes and serum creatinine levels. A total of 288 allografts were transplanted, 77 were in 75 children with LUTD, of which 46 received intervention. Patient survival was 100% in the intervention group and 97% in the nonintervention group (P = 0.815). Death‐censored graft survival was 96% and 100% respectively (P = 0.688). In the groups receiving intervention pretransplant or post‐transplant, graft survival rates were 95% and 100% respectively (P = 0.476). The follow‐up serum creatinine levels were higher in the pretransplant intervention group (P < 0.001). Interventions for dysfunctional bladders can be performed safely in paediatric renal transplant recipients. The mode of intervention and timing of intervention, in relation to transplant, do not influence outcomes if guided by careful assessment and investigation.
