To assess the flow rate obtained by catheters used in self intermittent catheterization.
In vitro comparative study designed to compare the average flow rate obtained by intravesical catheters, by repeated flowmetric measures. The catheters studied were the most used in France in Fr10, 12 and 14 for female catheters and in Fr12, 14 and 16 for male catheters.
We observed a strict relationship between Charriere and flow rate, both in female and male catheters These results were statistically significant (P<0.05). For female catheters, the average flow rate varied from 2.83 to 3.7 mL/s for Fr10 catheters, from 4.31 to 5.35 mL/s for Fr12 catheters and from 7.00 to 7.85 mL/s for Fr14 catheters (P<0.05). For male catheters, the average flow rate varied from 4.53 to 5.00 mL/s for Fr12 catheters, from 6.95 to 8.17 mL/s for Fr14 catheters and from 10.4 to 11.07 mL/s for Fr16 catheters (P<0.05). In female and male population, despite the observed flow rate differences between catheters, there were no statistically significant differences.
This study demonstrated a better flow rate when Charriere increases. Thus, an objective adaptation of self catheterization's materiel is possible when the patient wishes to improve flow rate in order to reduce self intermittent catheterization duration.
评估用于自我间歇性导尿的导管所获得的流速。
进行体外对比研究，旨在通过反复的流量测量比较膀胱内导管所获得的平均流速。所研究的导管是法国女性导管中最常用的Fr10、12和14型号，以及男性导管中最常用的Fr12、14和16型号。
我们观察到，无论是女性导管还是男性导管，导管规格（法制）与流速之间都存在严格的关系。这些结果具有统计学意义（P<0.05）。对于女性导管，Fr10型号导管的平均流速在2.83至3.7毫升/秒之间，Fr12型号导管为4.31至5.35毫升/秒，Fr14型号导管为7.00至7.85毫升/秒（P<0.05）。对于男性导管，Fr12型号导管的平均流速在4.53至5.00毫升/秒之间，Fr14型号导管为6.95至8.17毫升/秒，Fr16型号导管为10.4至11.07毫升/秒（P<0.05）。在女性和男性群体中，尽管观察到不同导管之间的流速存在差异，但差异无统计学意义。
本研究表明，随着导管规格（法制）增大，流速更佳。因此，当患者希望提高流速以缩短自我间歇性导尿持续时间时，有可能对自我导尿材料进行客观调整。
