The correlation between bladder trabeculation degrees and urodynamic findings in benign prostatic hyperplasia / 中华泌尿外科杂志

ABSTRACT

Objective To analyze the relationship between bladder trabeculation degrees and the urodynamic findings in patients with benign prostatic hyperplasia (BPH). Methods A total of 358 patients with BPH were included.Based upon the urethrocystoscopy, the bladder trabeculation degree was divided into 4 grades:Grade 0-no bladder trabeculation;Grade 1-mild to moderate;Grade 2-severe;Grade 3-severe with formation of pseudo-diverticula.We analyzed the relationship between the bladder trabeculation found by fiber urethrocystoscopy and the urodynamic findings such as maximum flow rate (Qmax),P Qmax.Watte factor,compliance and residual urine volume.For statistical analysis AVOVA (analysis of variance) and Spearman correlation were used. Results In the 358 cases,the bladder trabeculation degrees were as follows:Grade 0,21 cases;Grade 1,228 cases;Grade 2,82 cases and Grade 3,27 cases.A significant correlation was found between bladder trabeculation and the urodynamic findings.As the degree of bladder trabeculation increased,Qmax decreased (Grades 0 to 3:11.50?1.13,10.28? 2.29,9.80?0.98,7.36?1.37 ml/s,respectively;F=22.43,P
