Evaluation of bladder function after gastrocystoplasty / 重庆医科大学学报

ABSTRACT

Objective:To evaluate the function of bladder after gastrocystoplasty.Methods:38 patients after gastrocystoplasty were analyzed by observing the micturition and examination of urodynamics and to investigate the function of bladder during the filling and the micturition.Results:In the 38 patients,voiding interval time was 3.2?1.7hours;unirary output was 320?110ml;maximual flow rate was 19?7.2 ml per second;intravcsical pressure during filling was 11.2?8.2 cmH 2O;maximual intravesical pressure during voiding was 58?21 cmH 2O;and maximual pressure of detrusor was 28?12 cmH 2O.In total 38 cases,residual urine was observed in 11 cases,and residual volume was 55?34ml.12 cases developed uracratia or enuresis.Conclusion:Filling function of bladder is satisfactory after gastrocystoplasty,the micturition is carried out mainly by the action of intra-abdominal pressure.The disturbance of function of the sensation of bladder and the urethral sphincter is possibly the common cause for uracratia or enuresis.
