AIM: To compare the qualitative and quantitative features among untreated polypoidal choroidal vasculopathy(PCV), neovascular age-related macular degeneration(nv-AMD) and central serous chorioretinopathy(CSC) using optical coherence tomography(OCT) and OCT angiography(OCTA).METHODS: This retrospective study included 16 eyes with thin-choroid PCV, 18 eyes with thick-choroid PCV, 16 eyes with nv-AMD and 17 eyes with CSC, respectively. The indicators were obtained by OCT and ***: Sub-foveal choroidal thickness(SFCT) in CSC was thicker compared to other groups(all P<0.05). SFCT in nv-AMD was thicker compared to thin-choroid PCV, but thinner compared with thick-choroid PCV(both P<0.05). As the ratio of thickness of Haller's layer to thickness of SFCT, which of thin-choroid PCV was significantly higher than CSC(P<0.001). Likewise, thick-choroid PCV had significantly higher ratio than nv-AMD(P=0.016) or CSC(P<0.001). There were differences among them in pigment epithelium detachment(PED). The whole-superficial retinal vessel density(RVD), deep RVD and choroidal capillary vessel density(CCVD) in CSC were significantly higher compared to other three groups, respectively(all P<0.05). The whole CCVD in nv-AMD was higher compared to thick-choroid PCV(P=0.032). Cross-sectional local angiographic form was 87.50%, 83.33%, 0 and 35.29% in thin-choroid PCV, thickchoroid PCV, nv-AMD and CSC, respectively. Cross-sectional diffuse angiographic form was 12.50%, 16.67%, 100% and 5.88% in thin-choroid PCV, thick-choroid PCV, nv-AMD and CSC, ***: Combination of OCT and OCTA can effectively observe the significant alterations existed in PCV, CSC and nv-AMD, and there are distinctive differences among them. The pathogenesis is not exactly the same between PCV and nv-AMD, or PCV and CSC.

Receiver operating characteristic curve analysis revealed that the area under the curve for MPV to predict arteriogenic ED was 0.707. MPV≥9.65 fl was recognized as a cut-off value for potential arteriogenic ED (sensitivity:47.5%;specificity:91.7%).A significant inverse correlation was detected between MPV and lO-min peak systolic velocity (PSV)(r =-0.34;P <0.001)in the arteriogenic ED *** findings suggest that the MPV might be a powerful indicator to predict and diagnose arteriogenic ED,and MPV may be a marker for ED when using pDUS.

The application of laparoscopic Doppler ultrasound during laparoscopic varicocelectomy in infertile men

引用

Asian Journal of Andrology 2017年第2期19卷 214-218页

作者： Li-Qiang Guo Xiu-Lin Zhang Yu-Qiang Liu Wen-Dong Sun Sheng-Tian Zhao ming-zhen yuan Department of Urology The Second Hospital of Shandong University Jinan Shandong 250033 China Institute of Urology Shandong University Jinan Shandong 250033 China

The aim of this study is to evaluate the benefits of laparoscopic Doppler ultrasound （LDU） application during laparoscopic varicocelectomy （LV）, and to compare the surgical outcomes and complications between LDU-assisted LV （LDU-LV） and conventional LV for infertile patients with varicoceles; 147 infertile patients were randomly divided into two groups. Operative and postoperative parameters, semen parameters, and the pregnancy rate were compared. There were no differences in baseline demographics. The operative time was significantly longer in LDU-LV group than LV group. The incidence of postoperative hydrocele was 1.4% （1/72） in LDU-LV group versus 10.7% （8/75） in LV group, which showed a significant difference （P〈 0.05）. However, other surgical outcomes, such as postoperative hospital stay, postoperative recurrence, and testicular atrophy, were similar between the two groups. Sperm concentration and sperm motility were significantly increased in both groups at 3, 6, and 12 months after surgery （P 〈 0.01）, and they were higher in LDU-LV than LV group in 12 months after surgery （34.21 ± 6.36 vs 29.99 ± 6.04 for concentration, P〈 0.05; 40.72±8.12 vs 37.31 ± 6.12 for motility, P〈 0.05）. Sperm morphology was comparable between the two groups. The pregnancy rate showed no significant difference （44.4% of the LDU-LV vs 37.3% of the LV, P〉 0.05）. In conclusion, compared with LV, LDU-LV could safely and effectively ligate all spermatic veins and preserve spermatic arteries without leading to high varicocele recurrence and postoperative hydrocele. Given the benefits that sperm counts as well as sperm motility favoring LDU-LV, we recommend that LDU should be routinely used as an effective tool to improve outcomes and safety of laparoscopic varicocelectomy.

Although elevated prolactin levels have been shown to inhibit penile erection,the relationship between prolactin and erection of the penile tip or base has not been extensively *** therefore investigated the prolactin's effects on erecti on of the penile tip and base,with a cross-secti onal study of 135 patie nts with erectile dysfuncti on,based on scores of M21 on the In ternational Index of Erectile *** patients were tested for nocturnal penile tumescenee,blood pressure,serum glucose,total cholesterol,triglyceride,high-density lipoprotein,low-density lipoprotein,luteinizing hormone,follicle-stimulating hormone,prolactin,estradiol,testosterone,and *** and multivariate analyses were used to assess the associations between prolactin levels and erection at the penile tip and *** found no obvious relati on ship between erection time at penile tip and prolactin levels,but observed a negative correlation between base erection time and prolactin level(hazard ratio:-2.68;95%confidence interval[Cl]:-5.13-0.22).With increasing prolactin concentration,multivariate analysis showed obvious reduction in base erection time among patients with normal Rigiscan results(hazard ratio:-3.10;95%Cl:-7.96-1.77;P<0.05).Our data indicate that prolactin inhibits penile erection,particularly at the penile *** addition,when the effective erection time of the penile base lasts longer than 10 min,prolactin has a more obvious inhibitory effect on penile base erection.
