摘　　要：目的了解不同性别新生儿排尿参数的差异。方法选取2010年3月至2011年3月新生儿室出生3～7d的54例早产儿（男26例，女28例）和48例足月儿（男30例，女18例）作为研究对象，连续观察12h（9：00Am-9：00Pm）的自由排尿情况。记录每次排尿时间、排尿量、残余尿量（PRV）、是否伴排大便、排尿时觉醒状态等参数；并记录液体总入量。比较不同性别新生儿排尿间隔时间、最大膀胱容量、膀胱排空率（BER）等参数。结果54例早产儿共排尿318次（男156次，女162次），其中排尿时伴排大便40次（男16次，女24次）。男女早产儿PRV、BER比较差异均有统计学意义[（1．9±0．9）mL比（0．9±0．8）mL和8．3％比44．1％，P均〈0．01]，但排除BER的影响后，男女早产儿PRV为（2．1±0．5）mL比（1．8±0．6）mL，差异无统计学意义；48例足月儿排尿350次（男222次，女128次），其中43次排尿时伴排大便（男32次，女11次）。男女足月儿BER比较差异有统计学意义（15．3％比43．0％，P〈0．0001）；排尿伴排大便时，男女早产儿及足月儿BER比较（25．0％比41．7％，28．1％比36．4％），差异均无统计学意义（P均〉0．05）。结论和女童相比，男童新生儿更易发生排尿后膀胱残余尿现象。Objective To investigate the effects of gender on the newbom＇s voiding patterns. Methods One hundred and two healthy, single birth newborns [ 54 cases were preterm （26 male, 28 female） and 48 cases were full term（30 male, 18 female ） without low urinary tract pathological diseases, hospitalized in NICU from Mar. 2010 to Mar. 2011 were recruited in this study. Twelve hours（9 ： 00 Am -9 ： 00 Pro） observation of free voiding was per- formed. The voiding interval time （ VIT ） , bladder emptying rate （ BER ） , voiding volumes （ VV ） , post-void residual volumes（PRV） ,bladder capacity（BC）, voiding times, state of consciousness at voiding and the number of defecate simultaneously at voiding（DSV） as well as fluid intake were recorded and analyzed, retrospectively. Results The total times of voiding and DSV of the preterm neonates were 318 and 40 times, respectively. VIT and BC between male and female preterm newborns had no statistical significance. The mean PRV of the male was larger [ （ 1.9 -＋ 0.9 ） mL vs （0. 9 -＋ 0.8） roLl and the BER was lower（8.3% vs 44.1% ） than those of the female newborns（ all P 〈 0.01 ）. If re- ject the effect of BER was removed, the difference of PRV between the 2 genders [ （2.1 -＋ 0.5 ） mL vs （ 1.8 ＋- O. 6 ） mL] had no statistical significance. The total number of voiding and DSV of the term neonates were 350 and 43 times, respectively. The BER of the female term neonates was higher than that of the male term neonates（43.0% vs 15.3% , P 〈 0. 0001 ）. BC and the mean PRV between the 2 genders of term newborns had no statistical significance. Compared with the female neonates of the same gestational age,the difference of BER of the male neonates had no statistical sig- nificance any more when defecating simultaneously at voiding（ preterm 41.7% vs 25.0% ; full term 36.4% vs 28.1% , all P 〉 0.05 ）. Conclusion Compared with female, male newborns are more likely to have post-void residual volumes.
