Introduction: Graft function on long term into patients with LUTD is still a myth, So, we 
aimed know the natural history of LUTD and graft function into patient with abnormal lower 
urinary tract. Patient and methods: The study was conducted by retrospective review of 129
files of pediatric live renal transplant patients; Patients in either group had clinical evaluation 
of lower urinary tract function and assessment of graft functions at least one year after RT.
Results: On evaluation the magnitude of change of cystometric variables we found 57% 
improvement of incidence of urodynamic detrusor overactivity and 48% improvement in 
patient categorized as poor/decreased compliance. There was 90% increase in the number of 
patients with adequate capacity. Patients showed 55.5% decrease in the number of patient 
with high PVR. Conclusion: Live donor renal transplant into pediatric patients with LUTD 
due to organic or neurogenic lower urinary tract pathology showed high serum creatinine on 
long term follow up.
