Abstract: protrusion measured by ultrasound for diagnosing bladder outlet obstruction.Methods A literature search of medline (1966.1-2011.6),embase(1984.1-2011.6),CNKI (1994.1-2011.6) and WEIPU Data (1989.1-2011.6) from 1999 to 2009 was performed by two reviewers independently.QUADAS items was applicated to assess trial quality.Golden standard was BOOI measured by urodynamics (BOOI more than 40 indicates bladder outlet obstruction).Heterogenous studies and meta-analysis were conducted by Meta-Disc 1.4 software.Results Totally 6 studies was included at last,involving 682 subjects.No threshold effect was found,but there was heterogeneity due to other factors.The meta-analysis showed that the sensitivity was 70.8 ％,specificity was 87.6 ％,positive LR was 5.132,negative LR was 0.303,the diagnostic OR was 22.18,the area under SROC curve was 0.8723 and Q index was 0.8028.Conclusions Intravesical prostatic protrusion measured by ultrasound is a good index for diagnosing bladder outlet obstruction in patients with benign prostate hyperplasia when intravesical prostatic protrusion is equal or more than 10mm.
