Abstract:
PURPOSE: There are ample experimental and clinical data showing that if the bladder does not receive a significant urine input for a prolonged period it suffers a reduction in capacity and develops hypertonicity. We investigated the urodynamic changes before and after renal transplantation in the patients of chronic renal failure(CRF) under dialysis. MATERIALS AND METHODS: Urodynamic evaluations were performed in 47 CRF patients(25 males and 22 females, average age : 39 years) prior to renal transplantation and 4 weeks after renal transplantation. The clinical notes of each of the patients were reviewed to ascertain the cause of renal failure, duration and type of dialysis. RESULTS: The maximal flow rate , voiding volume, voiding time, volume of first sensation of fullness and the volume of urge sense were abnormally low in the patients of CRF, and the degree of deterioration was more remarkable in the patients of longer duration of dialysis, but the voiding detrusor pressure was within normal range in the patients of CRF irrespective of duration and type of dialysis. The maximal flow rate, voiding volume, voiding time, volume of first sensation of fullness and the volume of urge sense were increased significantly after successful renal transplantation, but the change of voiding detrusor pressure was not significant. CONCLUSIONS: The bladder capacity of CRF patients under dialysis is decreased to physiologic disuse state because of decreased urine input into the bladder for a prolonged period, but the contractility is well preserved irrespective of duration of dialysis, and the bladder capacity is recovered in the course of time after successful renal transplantation.
