膀胱内前列腺突入程度与膀胱结石相关性的研究

The correlation between intravesical prostatic protrusion and bladder stone in patients with benign prostatic hyperplasia

目的探讨膀胱内前列腺突入程度与前列腺增生患者膀胱结石形成的相关性。方法选取2017年10月至2019年3月大连市中心医院收治的前列腺增生患者170例。其中合并膀胱结石患者35例,定义为结石组;未合并膀胱结石患者135例,定义为增生组。CT检查扫描膀胱前列腺的横断面及矢状位、冠状位,通过测量前列腺的3个径线,计算出前列腺体积、矢状位尿道平面测量膀胱内前列腺突入程度。患者进行压力-流率测定,尿动力学参数包括PVR、Qmax、Pdet-Qmax。记录并评估患者临床资料、相关测量指标。结果两组患者年龄、BMI、术前PSA、前列腺体积等临床资料比较差异均无统计学意义。组间IPP对比差异有统计学意义(P<0.05)。结论膀胱内前列腺突入程度与前列腺增生患者膀胱结石形成具有相关性。随着IPP的增大膀胱结石形成也逐渐增高。

Objective To explore the correlation between the degree of intravesical prostate protrusion and the formation of bladder stones in pa tients with benign prostatic hyperplasia.Methods From October 2017 to March 2019,170 patients with benign prostatic hyperplasia who were ad mitted in Dalian Central Hospital were analyzed.35 patients with bladder calculi were defined as calculi group,and 135 patients without bladder cal culi were defined as hyperplasia group.The transverse,sagittal and coronal positions of the bladder and prostate were scanned by CT.The volume of the prostate and intravesical prostate protrusion were calculated by measuring the three diameters of the prostate.Urodynamic parameters included PVR,Qmax and Pdet-Qmax.Record and evaluate the clinical data and related measurement indicators of patients.Results There was no significant difference in age,BMI,preoperative PSA and prostate volume between the two groups.There was significant difference in IPP between two groups.Conclusion The degree of intravesical prostate protrusion is correlated with the formation of bladder stones in patients with benign prostatic hyper plasia.
