ABSTRACT
Purpose: Suprapubic bladder aspiration(SBA) of urine is the most reliable method to obtain urine avoiding contamination in non-toilet trained infants. Ultrasonography is a useful tool for guiding the anatomic location as well as for direct visualization during procedure. We evaluated the success rate and complication of ultrasound(US) assisted SBA Methods. Sixty infants who visited Ewha Womans University Mokdong Hospital, with suspected urinary tract infection were randomly divided into the US assisted (n=32) and blind SBA(control, n=28) group. In US assisted SBA group, the anteroposterior(AP), transverse, and sagittal diameters and the volume of the bladder were measured. In the blind SBA group, urine was blindly aspirated when the urinary bladder was palpated at the suprapubic area. The rate of successful urine aspiration, the number of attempts until successful aspiration, aspirated urine volume were compared between the two groups.
Results : The success rate was $100%$(32/32) in the US assisted group, which was significantly higher than $85.7%$(24/28) of the control group (P<0.05). The aspirated urine volume in the US assisted group was $7.4{pm}3.7;mL$, which was significantly higher than $4.5{pm}3.4;mL$ of the control group (P<0.05), The diameters and volume of bladder in successful aspiration were $2.1{pm}0.7;cm$ in AP diameter, $3.1{pm}0.6;cm$ in transverse diameter, $4.2{pm}1.0;cm$ in sagittal diameter and $15.2{pm}10.4;mL$ in volume, which were significantly higher than those ($1.7{pm}0.3;cm,;1.7{pm}0.3;cm,;1.8{pm}0.7;cm,;2.4{pm]0.6;cm,;3.9{pm}2.5$) of the control group (P<0.05) The correlations between the AP(r=0.78), transverse (r=0.72), sagittal(r=0.91) diameter and bladder volume were significant (P<0.05). SBA was $100%$ successful in the AP diameter >3 cm, transverse diameter >4 cm, depth >4 cm and bladder volume >5 mL.
Conclusion : US assistance can significantly improve the success rate of SBA in infant with suspected urinary tract infection. (J Korean Soc Pediatr Nephrol 2002 ; 6 : 68-74)
