Bladder function in an end-stage renal disease (ESRD) patient after kidney transplantation (KT) is a still unclear issue. After a long time of being defunctionalized, it is not known how the bladder achieves its normal functions again after KT. In this retrospective cohort study, 622 patients who received KT because of ESRD were reviewed. Duration of dialysis before KT was 59.4+-60.74 months, and the mean bladder capacity on pre-KT VCUG was 300.1+-149.8 ml. In 88 (14.1%) patients the bladder capacity was found to be under 100 ml (mean 82.2+-22.0 ml). In this group, the mean duration of dialysis was 98.6+-57.2 months. 42 (47.7%) patients had vesicoureteral reflux (VUR) and 4 (4.5%) had high postvoid residual urine (PVR). In the multivariate analysis, longer duration of dialysis, high PVR and having VUR were found as the significant factors associated with small bladder capacity. Lower urinary tract dysfunction after KT according low and normal bladder capacity was found as 4.5% (4 patients) and 5.2% (28 patients) respectively. Low pre-KT bladder volume is not always a problem after KT in ESRD. We must be alert in patients especially with previous bladder problems, VUR and high PVR.
