Abstract

Introduction: Accurate analysis of bladder stone composition is essential for appropriate treatment planning and recurrence prevention. The aim of this study was to evaluate the characteristics of bladder stone components in our center.

Materials and methods: A retrospective analysis on the composition of bladder stones collected in our center from January 2014 to March 2023 was conducted in the present work. Age, sex and laboratory examination of all patients were collected. Infrared spectroscopy was conducted for stone analysis.

Results: The most common stone component was calcium oxalate (43.0%), followed by uric acid (UA) stone (35.4%), calcium phosphate (12.10%), infection stone (9.0%) and cystine (0.5%). The highest stone prevalence appeared in patients aged over 60 years, and increased progressively with age. Furthermore, patients with UA stones were more likely to have a lower urinary pH. Additionally, patients with infection stones showed higher incidence of urinary tract infections than those with other types of stones. Patients with UA stones had higher average serum UA and creatinine levels. Uric acid stones are more likely to form multiple stones compared to stones of other composition. The volume of infectious stones is larger compared to stones of other compositions.

Conclusions: This study highlights the importance of gaining a deeper understanding of bladder stone composition, as it can lead to more effective evaluation, treatment, and prevention of stone disease.

中国江苏地区的膀胱结石成分：421 例结石分析结果。

导言：准确分析膀胱结石成分对制定适当的治疗计划和预防复发至关重要。本研究的目的是评估我们中心膀胱结石成分的特点。材料与方法：回顾性分析2014年1月至2023年3月在我中心采集的膀胱结石组成。收集所有患者的年龄、性别及实验室检查结果。采用红外光谱法对石料进行分析。结果：最常见的结石成分为草酸钙（43.0%），其次为尿酸结石（35.4%）、磷酸钙结石（12.10%）、感染结石（9.0%）、胱氨酸结石（0.5%）。结石患病率最高的患者年龄在60岁以上，并随着年龄的增长而逐渐增加。此外，UA结石患者更可能有较低的尿ph。此外，感染结石患者的尿路感染发生率高于其他类型结石患者。UA结石患者的平均血清UA和肌酐水平较高。与其他成分的结石相比，尿酸结石更容易形成多个结石。感染性结石的体积比其他成分的结石要大。结论：本研究强调了深入了解膀胱结石组成的重要性，因为它可以更有效地评估、治疗和预防结石疾病。

期刊介绍： Concise but fully substantiated international reports of clinically oriented research into science and current management of urogenital disorders form the nucleus of original as well as basic research papers. These are supplemented by up-to-date reviews by international experts on the state-of-the-art of key topics of clinical urological practice. Essential topics receiving regular coverage include the introduction of new techniques and instrumentation as well as the evaluation of new functional tests and diagnostic methods. Special attention is given to advances in surgical techniques and clinical oncology. The regular publication of selected case reports represents the great variation in urological disease and illustrates treatment solutions in singular cases.
