Abstract
INTRODUCTION: Diagnostic pressure on endoscopy suites can result in stent removal not receiving the required priority and unnecessary morbidity for patients. As well as using stents with extraction strings, the introduction of a portable single-use flexible cystoscope for ureteric stent removal (Isiris™), offered an opportunity to negotiate these issues by relocating stent removal to the office/clinic. This study aimed to determine whether such flexibility reduced stent dwell time with the assumption this would improve patient experience and decrease associated complications. MATERIALS AND METHODS: A retrospective review of ureteric stents placed during stone procedures was undertaken. Data collection included; patient demographics; stent dwell times; the number of emergency department (ED) attendances and hospital readmissions; procedure cancellation rates and the number of urinary tract infections. RESULTS: In total, 162 stents were removed (113 Standard, 34 Isiris™, 15 via strings). Excess dwell time was reduced in both Isiris™ (median 1 day, mean 1.37 days, p = 0.0009) and Strings Groups (median 0.96 days, mean 0.96 days, p = 0.022) compared with the Standard Group (median 8 days, mean 15.34 days).ED attendances and readmissions were reduced by 33.5% and 22% respectively in the Isiris™ Group compared with the Standard Group. There were no ED attendances in the Strings Group. Reductions in length of stay, urine infections and cancellation on the day of procedures were also observed. CONCLUSIONS: The clinical flexibility provided by Isiris™ and 'stents on strings' has objectively improved patient experience and is associated with a reduction in complications as well as increasing diagnostic capacity and cost efficacy.
