Urinary foreign bodies can be a risk factor for urinary tract infection (UTI). A number of patients undergoing ureteropyeloscopy laser lithotripsy have ureteric stents in situ. This study aims to investigate possible association between ureteric stent dwell time and the presence of UTI between staged procedures of endoscopic ureteric stone treatment (ureteropyeloscopy). METHODS: A retrospective review of all adult patients who were treated under 7 urologists at a single institution (Royal North Shore Hospital) by ureteropyeloscopy laser lithotripsy or basket removal of upper tract urolithiasis, who already had been presented, was conducted from 01 January 2018 – 30 June 2019. Patient demographic data, pre-operative urine culture results, ureteric stent dwell time, intra-operative complications and post-operative complications were recorded. Data was analysed using IBM SPSS V24. Descriptive analyses were performed. Normally distributed data was analysed using independent t-tests and ANOVA; categorical variables were analysed using Chi-square and Fisher’s exact tests. P-values < 0.05 were considered statistically significant. RESULTS: 172 patients (mean age 56.1 years, range 24.1-93.9) were identified for this study. Of these patients, 23 patients (13.4%) underwent their secondary procedure with a stent dwell time of 1 month or less (Group A); whilst 149 patients (86.6%) underwent ureteropyeloscopy stone treatment with a stent dwell time greater than 1 month (Group B). Overall, 23.3% (40/172) patients booked for ureteropyeloscopy stone treatment had positive pre-operative urine culture results. Among Group A 4.3% patients had positive preoperative urine culture results whereas among Group B 26.2% patients had positive preoperative urine culture results. There was a statistically significant preoperative infection rate between the two groups (p < 0.05). CONCLUSIONS: In conclusion, longer duration of stent dwell time prior to secondary ureteroscopic treatment for upper tract stones is significantly associated with increased rate of positive pre-operative urine culture. Preoperative UTIs are a known risk factor for serious peri-operative complications such as urosepsis and can lead to subsequent morbidity and even mortality. Therefore, patients who have been prestented and are waitlisted for subsequent ureteropyeloscopy laser lithotripsy should be appropriately triaged to schedule their secondary procedure within an appropriate timeframe to help avoid possible serious negative outcomes.
