Abstract

Purpose

The current clinical guidelines recommend routine stone bacterial culture for patients who have undergone stone surgery. However, the results of bacterial culture are obtained after several days, which delay the implementation of early treatment postsurgery. In this study, we performed stone bacterial culture for several surgical patients and predicted the results and types of stone bacterial culture based on specific parameters on admission. This case provides important clinical data that will guide the implementation of early detection and management of postoperative infections.

Methods

Patients who underwent stone surgery between October 2023 and January 2024, all of whom underwent urine and stone bacterial culture were enrolled in the study. Their results were processed and compared using logistic regression analysis.

Results

A total of 165 patients were enrolled in the study, among whom 57 had positive stone cultures, 37 had positive urine culture (UC), and 21 had both positive stone and urine cultures. Univariate analysis indicated that the positive stone cultures were associated with preoperative UC and preoperative use of antibiotics. Multivariate logistic regression analysis further confirmed that positive preoperative UC was a significant risk factor for stone culture (SC). Patients with consistent results in both UC and SC exhibited larger kidney stone diameters. Furthermore, the combination of UC and stone diameter could effectively predict the bacterial species of SC (AUC = 0.817).

Conclusion

In patients with large-diameter kidney stones, the bacteria identified in UC were often similar to those detected in the SC.

术前尿培养结合结石直径常作为结石培养结果的指标

目的：目前的临床指南推荐对接受过结石手术的患者进行常规的结石细菌培养。然而，细菌培养的结果需要几天才能得到，这耽误了术后早期治疗的实施。在本研究中，我们对几例手术患者进行了石细菌培养，并根据入院时的具体参数预测了石细菌培养的结果和类型。本病例为指导术后感染的早期发现和处理提供了重要的临床数据。方法入选于2023年10月至2024年1月期间接受结石手术的患者，所有患者均接受尿液和结石细菌培养。使用逻辑回归分析对结果进行处理和比较。结果共纳入165例患者，其中57例结石培养阳性，37例尿培养阳性，21例结石和尿培养均阳性。单因素分析表明，结石培养阳性与术前UC和术前抗生素使用有关。多因素logistic回归分析进一步证实术前UC阳性是结石培养（SC）的重要危险因素。UC和SC结果一致的患者肾结石直径较大。UC与结石直径的结合可以有效预测SC的细菌种类（AUC = 0.817）。结论在大直径肾结石患者中，UC中检出的细菌与SC中检出的细菌相似。

期刊介绍： IJCP is a general medical journal. IJCP gives special priority to work that has international appeal. IJCP publishes: Editorials. IJCP Editorials are commissioned. [Peer reviewed at the editor''s discretion] Perspectives. Most IJCP Perspectives are commissioned. Example. [Peer reviewed at the editor''s discretion] Study design and interpretation. Example. [Always peer reviewed] Original data from clinical investigations. In particular: Primary research papers from RCTs, observational studies, epidemiological studies; pre-specified sub-analyses; pooled analyses. [Always peer reviewed] Meta-analyses. [Always peer reviewed] Systematic reviews. From October 2009, special priority will be given to systematic reviews. [Always peer reviewed] Non-systematic/narrative reviews. From October 2009, reviews that are not systematic will be considered only if they include a discrete Methods section that must explicitly describe the authors'' approach. Special priority will, however, be given to systematic reviews. [Always peer reviewed] ''How to…'' papers. Example. [Always peer reviewed] Consensus statements. [Always peer reviewed] Short reports. [Always peer reviewed] Letters. [Peer reviewed at the editor''s discretion] International scope IJCP publishes work from investigators globally. Around 30% of IJCP articles list an author from the UK. Around 30% of IJCP articles list an author from the USA or Canada. Around 45% of IJCP articles list an author from a European country that is not the UK. Around 15% of articles published in IJCP list an author from a country in the Asia-Pacific region.
