washing. In the wet procedure, the catheter was stored in a dilute povidone-iodine solution afterwashing with soap and water.Q2C.11. Catheter removal strategiesa. Clamping vs. free drainage prior to removalLow-quality evidence suggested no benefit of clamping versus free drainage before catheterremoval. 37,184This was based on no difference in risk of bacteriuria, urinary retention, orrecatheterization between the two strategies. One study comparing a clamp and release strategyto free drainage over 72 hours found a greater risk of bacteriuria in the clamping group.b. Postoperative duration of catheterizationModerate-quality evidence suggested a benefit of shorter versus longer postoperative durationsof catheterization. 37,184,227,228 This was based on a decreased risk of bacteriuria/unspecified UTI,decreased time to ambulation and length of stay, no differences in urinary retention and SUTI,and increased risk of recatheterization. Significant decreases in bacteriuria/unspecified UTI werefound specifically for comparisons of 1 day versus 3 or 5 days of postoperative catheterization.Recatheterization risk was greater in only one study comparing immediate removal to removal 6or 12 hours after hysterectomy.Q2C.12. Assessment of urine volumesLow-quality evidence suggested a benefit of using portable ultrasound to assess urine volume inpatients undergoing intermittent catheterization. 229,230 This was based on fewer catheterizationsbut no reported differences in risk of unspecified UTI. Patients studied were adults withneurogenic bladder in inpatient rehabilitation centers. Our search did not reveal data on the useof ultrasound in catheterized patients in other settings.Evidence Review Table 2C. What are the risks and benefits associated with differentcatheter management techniques?2C.1.2C.2.a.2C.2.b.2C.3.a.2C.3.b.2C.4.Unless clinical indications exist (e.g., in patients with bacteriuria upon catheterremoval post urologic surgery), do not use systemic antimicrobials routinely asprophylaxis for UTI in patients requiring either short or long-term catheterization.(Category IB)Further research is needed on the use of urinary antiseptics (e.g., methanamine) toprevent UTI in patients requiring short-term catheterization. (No recommendation/unresolved issue)Further research is needed on the use of methanamine to prevent encrustation inpatients requiring chronic indwelling catheters who are at high risk for obstruction.(No recommendation/unresolved issue)Unless obstruction is anticipated (e.g., as might occur with bleeding after prostatic orbladder surgery), bladder irrigation is not recommended. (Category II)Routine irrigation of the bladder with antimicrobials is not recommended. (Category II)Routine instillation of antiseptic or antimicrobial solutions into urinary drainage bagsis not recommended. (Category II)< 原文 > VIII. Evidence Review93
