RESUMEN

OBJECTIVES: To identify risk factors for infectious complication of ureteroscopy after obstructive acute pyelonephritis (OAPN). PATIENTS AND METHODS: This single-center, retrospective cohort study (#20200002, retrospectively registered in February 1st, 2020) included patients who underwent emergency drainage for OAPN and subsequently underwent ureteroscopic stone removal between January 2006 and December 2020. Multivariable analysis was conducted using demographic and stone-related factors to determine those that could predict postoperative febrile urinary tract infection (UTI). RESULTS: Overall, 432 patients underwent ureteroscopy after OAPN. The stone-free rate was 84.3%, whereas the overall and major complication rates were 17.6% and 3.2%, respectively. A total of 70 (16.2%) patient developed febrile UTI, among whom 34 (7.9%) and 11 (2.5%) developed sepsis and severe sepsis, respectively. Multivariable analysis identified diabetes mellitus [odds ratio (OR) 1.98, 95% confidence interval (CI) 1.05-3.74], duration from drainage to surgery >1 month (OR 2.28, 95% CI 1.20-4.74), and simultaneous retrograde intrarenal surgery (OR 2.96, 95% CI 1.35-6.48) as significant risk factors for UTI. After dividing patients into low- (0), intermediate- (1), and high- (2-3) risk groups according to the number of factors they had, the risk of postoperative UTI was 6.3%, 14.5%, and 27.7%, respectively (p for trend <0.001). CONCLUSIONS: Patients who underwent ureteroscopy after OAPN were at risk for postoperative UTI, despite its efficacy. Simultaneous retrograde intrarenal surgery should be carefully planned, especially for patients with diabetes mellitus or extended surgery wait times.

RESUMEN

Prognostic accuracy of the quick sequential organ failure assessment (qSOFA) score for mortality may be limited in elderly patients. Using our multi-institutional database, we classified obstructive acute pyelonephritis (OAPN) patients into young and elderly groups, and evaluated predictive performance of the qSOFA score for in-hospital mortality. qSOFA score ≥ 2 was an independent predictor for in-hospital mortality, as was higher age, and Charlson comorbidity index (CCI) ≥ 2. In young patients, the area under the curve (AUC) of the qSOFA score for in-hospital mortality was 0.85, whereas it was 0.61 in elderly patients. The sensitivity and specificity of qSOFA score ≥ 2 for in-hospital mortality was 80% and 80% in young patients, and 50% and 68% in elderly patients, respectively. For elderly patients, we developed the CCI-incorporated qSOFA score, which showed higher prognostic accuracy compared with the qSOFA score (AUC, 0.66 vs. 0.61, p < 0.001). Therefore, the prognostic accuracy of the qSOFA score for in-hospital mortality was high in young OAPN patients, but modest in elderly patients. Although it can work as a screening tool to determine therapeutic management in young patients, for elderly patients, the presence of comorbidities should be considered at the initial assessment.
