摘要对脑瘫儿童膀胱功能的影响。方法本组病例为行F-SPR的脑瘫儿童97例。术前1周和术后6个月行膀胱平均功能容量(AFBV)测定和尿流动力学检查。结果痉挛型脑瘫术前下尿路症状（LUTS）发生率为34.24%,混合型发生率为58.33%;术后分别下降至20.54%和29.16%。尿流动力学检查36例中术前26例（72.22%）存在尿流动力学指标异常，其中18例（69.23%）无临床症状。AFBV和尿流动力学指标术后改善明显，L2～S1 节段SPR较L5～S1节段SPR改善明显。结论约50%脑瘫儿童合并有临床静止性膀胱功能障碍。F-SPR在有效缓解下肢痉挛的同时，可改善膀胱贮尿功能，减少上尿道并发症。

abstractsObjective　To evaluate the influence of functional selective posterior rhizotomy （F-SPR）on bladder function in children with cerebral palsy.　Methods　We reviewed average functional bladder volume(AFBV) and urodynamics in 97 patients with cerebral palsy who had undergone F-SPR for spasticity before and after operation.　Results　The incidence of low urinary tract symptom was 34.24% in patients with spastic cerebral palsy before operation, and 58.33% in the mixed type, but they were 20.54% and 29.16% respectively after operation. Of 36 patients subjected to preoperative urodynamic studies, the total bladder capacity (TBC) and pressure specific volume(PSV) were abnormal for age in 26(72.22%). In addition, 18 of 26 children (69.23%)were completely asymptomatic.In the group subjected to preoperative and postoperative urodynamic studies, there was significant improvement in AFBV,TBC and PSV. More significant improvement was noted in all three indexes in the L2-S1SPR group than in the L5-S1　SPR group.　Conclusions　At least half of children with spastic cerebral palsy have clinically silent bladder dysfunction.F-SPR improves spasticity and significantly improves bladder storage function.
