Urodynamic studies have been carried out in 10 boys with the prune belly syndrome. In spite of gross radiological changes the condition is compatible with normal voiding dynamics. Filling cystometrograms show a marked shift to the right. Pressure/flow studies may demonstrate an unbalanced voiding mechanism which can be treated by urethrotomy. Following urethrotomy urethral pressure profiles showed a significant fall, flow rates increased and residual urine volumes were reduced. Urological treatment in the prune belly syndrome should be directed at producing a bladder which empties well: a balanced voiding mechanism. Urodynamic investigations are helpful in achieving this aim. Residual urine determination and flow rates should be used in routine follow-up. Urethrotomy to lower bladder outflow resistance is advocated as one of the first steps in treating the unbalanced voiding mechanism that is often found in the prune belly syndrome.
对10名患有梅干腹综合征的男孩进行了尿动力学研究。尽管存在明显的放射学改变，但该病症与正常排尿动力学相符。充盈性膀胱测压图显示明显右移。压力/流率研究可能显示排尿机制失衡，可通过尿道切开术进行治疗。尿道切开术后，尿道压力分布图显示显著下降，流速增加，残余尿量减少。梅干腹综合征的泌尿外科治疗应旨在使膀胱良好排空：建立平衡的排尿机制。尿动力学检查有助于实现这一目标。在常规随访中应使用残余尿量测定和流速测量。提倡将降低膀胱流出阻力的尿道切开术作为治疗梅干腹综合征中常见的排尿机制失衡的首要步骤之一。
