Fifty-six patients 5.9-15.2 years old with dysfunctional elimination syndrome (DES) unimproved by previous therapies were randomly distributed into two voiding training programs: group 1 contained 26 patients submitted to 24 training sessions over a 3-month period; group 2 contained 30 patients submitted to 16 sessions over a 2-month period. Both groups adhered to a voiding and drinking schedule, received instruction on adequate toilet posture, were reinforced through the maintenance of voiding diaries, and went through proprioceptive and pelvic floor muscle training (Kegel exercises). Group 2 patients also received biofeedback therapy. Clinical evaluation was carried out before each program's initiation and 1, 6, and 12 months after each program's termination. All patients were submitted to renal ultrasonography and dynamic ultrasonography before and 6 months after each program's conclusion. Millivoltage recordings of pelvic floor muscles were compared before and after training. Urinary continence was improved after completion of either training program. Only those patients who received biofeedback training showed a significant decrease in postvoiding residual (PVR) urine as detected by dynamic ultrasonography. Our results show that either training regime can reduce episodic urinary incontinence and urinary tract infection but that further study is required to identify the optimal training duration.

小儿功能障碍。骨盆底运动或生物反馈疗法：一项随机研究。

先前治疗未改善的59例5.9-15.2岁的功能障碍消除综合征（DES）患者被随机分配到两个排尿训练计划中：第1组包含26名患者，在3个月内接受了24次训练；第2组中有30名患者在2个月内接受了16次治疗。两组均遵守排尿和饮酒时间表，接受有关适当坐便姿势的指导，通过维持排尿日记得到加强，并接受了本体感觉和骨盆底肌肉训练（Kegel锻炼）。第2组患者也接受了生物反馈治疗。在每个程序开始之前以及每个程序终止后的1、6和12个月进行临床评估。在每个程序结束之前和之后6个月，所有患者均接受了肾脏超声检查和动态超声检查。对比训练前后骨盆底肌肉的毫伏记录。两项训练计划均完成后，尿失禁得到改善。通过动态超声检查发现，只有那些接受过生物反馈训练的患者才显示出避免排尿后残余尿（PVR）的显着减少。我们的结果表明，任何一种训练方案都可以减少发作性尿失禁和尿路感染，但是需要进一步的研究来确定最佳的训练时间。完成任何一项训练计划后，尿液尿失禁均得到改善。通过动态超声检查发现，只有那些接受过生物反馈训练的患者才显示出避免排尿后残余尿（PVR）的显着减少。我们的结果表明，任何一种训练方案都可以减少发作性尿失禁和尿路感染，但是需要进一步的研究来确定最佳训练时间。两项训练计划均完成后，尿失禁得到改善。通过动态超声检查发现，只有那些接受过生物反馈训练的患者才显示出避免排尿后残余尿（PVR）的显着减少。我们的结果表明，任何一种训练方案都可以减少发作性尿失禁和尿路感染，但是需要进一步的研究来确定最佳的训练时间。
