| 2 | Can intravesical prostatic protrusion predict bladder outlet obstruction even in men with good flow?显示文摘Objective:Men with benign prostate hyperplasia(BPH)with good urinary flow may still have bladder outlet obstruction(BOO).Intravesical prostatic protrusion(IPP)has been shown to be able to predict BOO.We aim to investigate the use of IPP to predict BOO in men with good urinary flow.Methods:One hundred and fourteen consecutive men(>50 years old)presenting with lower urinary tract symptoms suggestive of BPH were recruited in 2001 and 2002.They were evaluated with serum prostate specific antigen(PSA),uroflowmetry and transabdominal ultrasound measurement of IPP and prostate volume(PV).Pressure-flow urodynamic studies were performed on all men and BOO was defined by BOO index>40.Men with Qmax12.0 mL/s were considered to have good flow.Results:Among the 114 men,61 patients had good urinary flow.Their median age,PV and Qmax were 66 years,32.9 mm3 and 14.5 mL/s respectively.14/61(23.0%)patients had BOO and their distribution of IPP were as follows:Grade 1 e 0/20(0%)obstructed,Grade 2 e 6/22(27.3%)and Grade 3 e 8/19(42.1%).Sensitivity of Grade 2/3 IPP for BOO was 100% while specificity of Grade 3 IPP was 76.6%.The area-under-curve(AUC)for IPP was greater than that for PV(0.757 vs.0.696).Conclusion:Even in men with good flow,high grades of IPP were more likely to have BOO and hence,may be a useful adjunct to predict BOO. | Alvin Lee Han Jie Lee Kok Bin Lim Hong Hong Huang Henry Ho Keong Tatt Foo | 2016 | Asian Journal of Urology2016，3，1： | 4 |
| 3 | Patients with small prostates and low-grade intravesical prostatic protrusion e A urodynamic evaluation显示文摘Abstract Objective:Despite high-grade intravesical prostatic protrusion(IPP)being closely related to bladder outlet obstruction(BOO),up to 21%of patients with low IPP remain obstructed.This study evaluates the characteristics and urodynamic findings of men with small prostates and low IPP.Methods:One hundred and fourteen men aged>50 years old with lower urinary tract symptoms(LUTS)were assessed with symptoms,uroflowmetry,serum prostate-specific antigen(PSA),transabdominal ultrasound measurement of prostate volume(PV),IPP and post-void residual urine(PVRU).All patients underwent pressure flow studies.Patients with PV<30 mL and IPP10 mm were examined for parameters correlating with BOO or impaired detrusor contractility.Results:Thirty-six patients had PV<30 mL and IPP<10 mm.Nine patients(25.0%)had urodynamic BOO,all with normal bladder contractility.Fourteen patients(38.9%)had poor detrusor contractility and all had no BOO.PV,PVRU and IPP were significantly associated with BOO,with IPP showing greatest positive correlation.Both Qmax and IPP were significantly associated with detrusor contractility.At 5-year follow-up,most patients responded to medical therapy.Only three out of nine patients(33.3%)with BOO eventually underwent surgery,and all had a high bladder neck seen on the resectoscope.Only one patient(7.1%)with poor detrusor contractility eventually required surgery after repeat pressure flow study revealed BOO.Conclusion:In men with small prostates and low IPP,the presence of BOO is associated with higher PV,PVRU and IPP,and most respond well to medical management.BOO can possibly be explained by elevation of the bladder neck by a small subcervical adenoma. | Han Jie Lee Alvin Lee Hong Hong Huang Palaniappan Sundaram Keong Tatt Foo | 2017 | Asian Journal of Urology2017，4，4： | 2 |

| 6 | Relevant Visual Semantic Context-Aware Attention-Based Dialog显示文摘The existing dataset for visual dialog comprises multiple rounds of questions and a diverse range of image contents.However,it faces challenges in overcoming visual semantic limitations,particularly in obtaining sufficient context from visual and textual aspects of images.This paper proposes a new visual dialog dataset called Diverse History-Dialog(DS-Dialog)to address the visual semantic limitations faced by the existing dataset.DS-Dialog groups relevant histories based on their respective Microsoft Common Objects in Context(MSCOCO)image categories and consolidates them for each image.Specifically,each MSCOCO image category consists of top relevant histories extracted based on their semantic relationships between the original image caption and historical context.These relevant histories are consolidated for each image,and DS-Dialog enhances the current dataset by adding new context-aware relevant history to provide more visual semantic context for each image.The new dataset is generated through several stages,including image semantic feature extraction,keyphrase extraction,relevant question extraction,and relevant history dialog generation.The DS-Dialog dataset contains about 2.6 million question-answer pairs,where 1.3 million pairs correspond to existing VisDial’s question-answer pairs,and the remaining 1.3 million pairs include a maximum of 5 image features for each VisDial image,with each image comprising 10-round relevant question-answer pairs.Moreover,a novel adaptive relevant history selection is proposed to resolve missing visual semantic information for each image.DS-Dialog is used to benchmark the performance of previous visual dialog models and achieves better performance than previous models.Specifically,the proposed DSDialog model achieves an 8% higher mean reciprocal rank(MRR),11% higher R@1%,6% higher R@5%,5% higher R@10%,and 8% higher normalized discounted cumulative gain(NDCG)compared to LF.DS-Dialog also achieves approximately 1 point improvement on R@k,mean,MRR,and NDCG compared to the original RVA,and 2 points improvement compared to LF andDualVD.These results demonstrates the importance of the relevant semantic historical context in enhancing the visual semantic relationship between textual and visual representations of the images and questions. | Eugene Tan Boon Hong Yung-Wey Chong Tat-Chee Wan Kok-Lim Alvin Yau | 2023 | Computers, Materials & Continua2023，76，8： | 0 |
