泌尿器科泌尿器科泌尿器科泌尿器科
腎臟病學 (nephrology) 是一種醫學專業.
手术瘤学手术瘤学

背景情况:

逆行性内手术 (RIRS) 后的残留结石是一个重大的临床挑战.
准确预测残留石头对于优化患者的治疗结果和手术规划至关重要.

研究的目的:

在RIRS之后,确定剩余石头的关键预测因素.
开发和验证一个基于nomogram的风险分层模型,用于预测RIRS后的剩余石头.

主要方法:

对274名因结石而接受RIRS治疗的患者进行了回顾性分析.
多变量逻辑回归和接收器操作特征 (ROC) 曲线分析以确定预测因素.
使用Python库开发和验证一个名ogram,通过对应指数 (C-index) 和校准图表进行评估.

主要成果:

石块体积> 498 毫米3,内骨盆角 (IPA) ≤ 44°,以及多个石头杯是残留石头的显著预测因素.
该名录显示出出色的预测性歧视 (C指数:0.839) 并将患者分为四个风险类别.
石头体积是一个比石头大小 (AUC: 0.793) 更强大的预测因素 (AUC: 0.819).

结论:

开发的诺米图,结合石块体积,IPA和干涉,是预测RIRS后残留石块的临床有价值的工具.
该模型的术前应用可以指导个性化治疗策略,并改善患者对预期结果的咨询.

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
