成人腹腔镜腹股沟疝修补术后尿潴留列线图风险预测模型建立

Establishment of an nomogram model for predicting the risk of urinary retention after laparoscopic inguinal hernia repair in adults

目的:构建个体化成人腹股沟疝患者行腹腔镜腹股沟疝修补术(LIHR)术后尿潴留(POUR)的列线图风险预测模型。方法:回顾性分析行LIHR的成人腹股沟疝患者447例的临床资料。进行统计学分析,筛选成人行LIHR发生POUR的独立危险因素,并构建列线图风险预测模型。结果:年龄≥65岁、良性前列腺增生、手术时间≥98 min是成人患者行LIHR发生POUR的独立危险因素(P<0.05)。基于以上3项独立危险因素成功构建列线图风险预测模型。使用随机拆分法进行模型验证,研究组和验证组校正曲线均与理想曲线拟合良好,研究组和验证组ROC曲线的AUC值分别为0.860、0.830。结论:年龄≥65岁、良性前列腺增生、手术时间≥98 min是成人行LIHR发生POUR的独立危险因素。

Objective:Construction of a nomogram risk prediction model of urinary retention(POUR)after laparoscopic inguinal hernia repair(LIHR)in individual adult inguinal hernia patients Methods:The clinical data of 447 adult inguinal hernia patients who underwent LIHR in Lanzhou University First Hospital from January 2018 to December 2021 were retrospectively analyzed.Statistical analysis was performed to screen independent risk factors for POUR after LIHR in adults,and to construct a nomogram risk prediction model.Results:age≥65 years,BPH and operation time≥98 min were independent risk factors for POUR after LIHR in adult patients.Based on the above three independent risk factors,a nomogram prediction model was successfully established.Using the random split method for model verification,the calibration curves of the study group and the verification group fit well with the ideal curve.The AUC values of the study group and the validation group were 0.860 and 0.830,respectively.Conclusion:Age≥65 years old,BPH and operation time≥98 min were independent risk factors of POUR afer LIHR in adults.The nomogram prediction model based on the samples of this study has high accuracy.
