Patients with chronic indwelling urinary catheters were studied to determine whether or not catheter irrigation with a sterile nonbacteriostatic solution should be part of routine care. One thousand catheter days were studied with catheters irrigated half of the time. Irrigation was found to be a costly and time-consuming procedure which had no effect on the patients' clinical course except to decrease the incidence of catheter plugging.
对长期留置导尿管的患者进行了研究，以确定用无菌非抑菌溶液进行导尿管冲洗是否应作为常规护理的一部分。对1000个导尿管日进行了研究，其中一半时间进行导尿管冲洗。结果发现，冲洗是一个成本高且耗时的过程，除了能降低导尿管堵塞的发生率外，对患者的临床病程没有影响。
