Objectives
To evaluate the role of video-urodynamic examination prior to renal transplantation.
Methods
Sixty-four kidney transplant recipients were included into the study. All patients underwent video-urodynamic examination and separate uroflowmetry. Results were evaluated based on daily mean amount of urine, duration of chronic renal failure and presence of diabetes mellitus.
Results
Thirty-five (54.6%) patients showed video-urodynamic abnormalities. The mean detrusor capacity was 234 ml, the mean detrusor compliance was 17.5 cm H2O/ml, the mean maximum detrusor pressure was 61.9 cm H2O and the mean Q
max was 13.8 ml/s in all patients. Vesicoureteral reflux was detected in 15 (23%) patients. The mean detrusor compliance and detrusor capacity significantly decreased as the daily amount of urine decreased and as the duration of chronic renal failure increased. Also, there was no significant relation between presence of diabetes mellitus and detrusor capacity and detrusor compliance.
Conclusion
Video-urodynamic studies before renal transplantation provide earlier diagnosis of lower tract abnormalities, which are likely to cause graft dysfunction.
