EVALUATION OF THE LOWER URINARY TRACT IN PATIENTS WITH END STAGE RENAL DISEASE

Lower urinary tract of 138 patients with end stage renal disease were evaluated by means of radiologic and urodynamic studies in all and endoscopic studies in selected cases.Urodynamic studies were performed before and 3 to 6 months after renal transplantation In 59 (42.8%) patients, 69 lower urinary tract abnormalities were found.The rates of abnormal urodynamic findings including unstable bladder, bladder hypocompliance and unobstructed low flow pattern were significantly higher in oligoanuric patients than the nonoligouric patients. Along with an increase in urine output after renal transplantation, these abnormal findings disappeared in all patients except one. To identify lower urinary tract abnormalities in patients with end stage renal disease, we suggest the routine use of free uroflowmetry and voiding cystourethrography as first step studies.Cystometric and endoscopic evaluations have limited indications in selected cases.
