Prospective cross-sectional study.
To investigate residual urine volumes after intermittent catheterization (IC) in men with spinal cord injury (SCI) and the effect of residual urine on the rate of symptomatic urinary tract infections (UTIs).
Single SCI rehabilitation center in Switzerland.
Sixty men experienced in IC (≥ 6 months) emptied their bladder twice by IC. Immediately after catheterization, residual urine was determined by ultrasonography. Personal characteristics and bladder diary details (annual UTI rate, catheter type) were also collected.
The median residual urine volume was 7.0 ml (lower quartile (LQ): 0.0, upper quartile (UQ): 20.3 ml). No residual urine was observed after 42% (n=50) of all catheterizations (n=120). Unsatisfactory residual volumes (that is, >50 ml) were observed after 9% (n=11) of all catheterizations. There was no significant (P=0.95) difference between the median residual urine volume of men with recurrent (>2 UTIs per year) UTIs (2.5 ml, LQ: 0.0, UQ: 29.3 ml) and the volume of those with sporadic (≤ 2 UTIs per year) UTIs (6.0 ml, LQ: 0.0, UQ: 20.0 ml).
Bladder evacuation by IC is an efficient method, resulting in zero or small residual urine volumes. The small residual urine volumes generally observed after IC do not predispose for UTIs.
前瞻性横断面研究。
研究脊髓损伤（SCI）男性间歇性导尿（IC）后的残余尿量以及残余尿量对症状性尿路感染（UTI）发生率的影响。
瑞士单一 SCI 康复中心。
60 名有 IC 经验（≥6 个月）的男性通过 IC 排空膀胱两次。导尿后立即通过超声检查确定残余尿量。还收集了个人特征和膀胱日记详细信息（年度 UTI 发生率、导管类型）。
中位残余尿量为 7.0ml（下四分位数（LQ）：0.0，上四分位数（UQ）：20.3ml）。42%（n=50）的所有导管（n=120）后均无残余尿。9%（n=11）的所有导管后残余尿量不理想（即>50ml）。复发性（>2 次/年）UTI 男性（2.5ml，LQ：0.0，UQ：29.3ml）和偶发性（≤2 次/年）UTI 男性（6.0ml，LQ：0.0，UQ：20.0ml）的中位残余尿量无显著差异（P=0.95）。
IC 排空膀胱是一种有效的方法，可导致零或少量残余尿量。IC 后观察到的少量残余尿量通常不会导致 UTI。
