Purpose: The evaluation of lower urinary tract (LUT) before transplantation is not required, except in patients with a history of LUT disfunction (LUTD). In this study, we adressed the necessity for lower urinary system evaluation in transplantation candidates classified according to their etiology. Materials and Methods: Sixty-two patients were prospectively evaluated. The patients were evaluated at 2 months preoperatively and at 6 months post transplantation using questionnaires, bladder diary and urodynamic studies. The end stage renal disease (ESRD) etiologies of the patients were divided into three groups as follows: patients with a parenchymal disease, patients with LUTD and those with unknown etiology and the obtained results were evaluated accordingly. Results: The evaluation of 50 patients revealed significant differences in ICIQ-SF (p < 0.001), IPSS (p < 0.001), daily urine volumes (p = 0.05), maximum urinary flow rate (p = 0.03), PVR, the number of patients with VUR and all cystometric parameters between the patient groups divided according to the etiology. The comparison of the groups to each other revealed no statistically significant differences in all parameters between the LUTD group and the patient groups with unknown etiology. Considering that the results from questionnaires of patients with a single voided volume of 100 cc or greater on the bladder diary would be scientifically more significant, they were evaluated separately. Thus, even though the results from questionnaires did not differ between the group with unknown etiology and the LUTD group, there were significant differences when compared to patients who developed ESRD due to a parenchymal disease. Similar findings were found between the results of urodynamic study. Conclusions: The evaluation of lower urinary tract in patients with a history of LUTD and in those with unknown etiology should be initially evaluated by noninvasive methods such as questionnaires and uroflowmetry.
