TI  - Extraction Strings for Ureteric Stents: Is There an Increased Risk for Urinary
      Tract Infections?
PG  - 936-940
LID - 10.1089/sur.2017.165 [doi]
AB  - BACKGROUND: To evaluate urinary tract infections associated with placement of
      ureteric stents, we performed a retrospective study and compared rates between
      patients with and patients without an extraction string attached to the ureteric 
      stent. Indwelling ureteric stents are routinely removed by cystoscopy. If an
      extraction string has been connected to the stent at the time of placement,
      however, the removal can be performed without an invasive procedure. Concerns
      exist regarding the risk for an unintentional dislocation, increased
      stent-related discomfort, or an increase of the post-operative urinary tract
      infection rate. METHODS: All elective transurethral ureteric stent placements
      performed between November 2011 and December 2012 in our department were included
      for this investigation. Urinary tract infection was defined according to the
      Centers for Disease Control and Prevention (CDC)/National Healthcare Safety
      Network (NHSN) surveillance definition of health-care-associated infections.
      Patients with an existing urinary tract infection at the time of admission were
      excluded from the analysis. RESULTS: A total of 342 patients receiving ureteric
      stents were evaluated regarding post-operative urinary tract infections. Of these
      patients, 127 (37.1%) had an extraction string and 215 (62.9%) a stent without a 
      string. The total urinary tract infection rate was 6.4% with no significant
      difference between the two groups (7.9% vs. 5.6%, p = 0.49). CONCLUSION: In the
      present study, we did not observe an increased rate of post-operative urinary
      tract infections in patients with an extraction string attached to the ureteral
      stent. Extraction string is a good option for patients to avoid cystoscopic stent
      removal.
