Neurogenic bladder is one of the causes of end stage renal disease (ESRD) and kidney transplantation (KTP) is the preferred method of therapy for it. We evaluated the results of urodynamic study (UDS) in ESRD patients and compared them with patient's symptoms and other pretransplantation tests. 28 patients with ESRD who were candidates for KTP referred to our urodynamic ward because of symptoms of voiding dysfunction included urinary frequency, urgency, urge incontinence, voiding problems or signs included vesicoureteral reflux, bladder trabeculation or low capacity in sonography or voiding cystourethrography (VCUG). History and physical examination were taken in all patients and then all of them underwent uroflowmetry followed by pressureflow study. Results of UDS and all above mentioned information were analyzed by IPSS soft wear. 10 patients were female and 14 were male with mean age of 31.1 years (ranged 21-49). The most frequent symptom was urinary urgency and the most frequent sign was bladder trabeculation. Total diuresis per day was significantly correlated with bladder capacity and compliance (p=0.001). Other positive correlations were between low bladder capacity in sonography or VCUG with low bladder capacity in filling phase (p=0.003), urge incontinence and uninhibited bladder contraction in UDS (p=0.01) and urge incontinence with uninhibited bladder contractions (p=0.005) and low compliance bladder (p=0.01). Urodynamic study appears to be a useful diagnostic method in minority of patients schedule for KTP. History of voiding problems, voiding diary and signs of voiding dysfunction in noninvasive methods such as sonography or VCUG can be useful in selection patients for more invasive methods included urodynamic study.
