The resonance® metallic ureteric stent in the treatment of chronic ureteric obstruction: a safety and efficacy analysis from a contemporary clinical series.

Abstract We evaluate the efficacy and safety of metallic ureteric stenting using the Cook Resonance® stent in the treatment of chronic ureteric obstruction of benign and malignant aetiology. Published experience of using this stent in this context is limited. We add to the body of literature on this topic.

AB  - BACKGROUND: We evaluate the efficacy and safety of metallic ureteric stenting
      using the Cook Resonance(R) stent in the treatment of chronic ureteric
      obstruction of benign and malignant aetiology. Published experience of using this
      stent in this context is limited. We add to the body of literature on this topic.
      METHODS: All patients who had a Resonance(R) metallic stent inserted between
      April 2009 and November 2014 in our institution were identified from a
      prospectively maintained stent-database. Primary outcome was relief of ureteric
      obstruction, defined by successful clinical and radiological treatment of
      hydronephrosis/hydroureter. Secondary outcome measures included operative time,
      radiological exposure, total stent dwell time (defined as the cumulative time in 
      months for which a Resonance(R) metallic stent was in situ), and early and late
      complications. RESULTS: Twenty-one patients underwent 52 stent insertion episodes
      (SIE). Median age was 58 years (range 39-90). Stent insertion resulted in
      successful treatment of hydronephrosis/hydroureter in 96% (2 SIE resulted in
      failure to relieve ureteric obstruction). Median operative time was 21 min (range
      12-90) Median radiation exposure was 815.3 cGy/cm2 (range 192.9-5366.3). Median
      stent dwell time was 19.5 months (range 6-52) in non-malignant and 12 months
      (range 2-48) in malignant ureteric obstruction. One stent migrated proximally
      during insertion and had to be retrieved using an antegrade approach. 5 patients 
      re-admitted with haematuria: all resolved without intervention or blood
      transfusion. 3 episodes of post-operative urinary infection were recorded; all
      were successfully treated with oral antibiotics. CONCLUSION: Metallic ureteric
      stenting using the Resonance(R) stent is safe and effective for treating ureteric
      obstruction from both malignant and benign causes. The success rate in our series
      is 96%.
