We investigated the effect of various tissue components along the shock wave path on the success of SWL. Materials and Methods From October 2008 to August 2010, a total of 206 patients with kidney stones sized 5 to 20 mm were prospectively recruited for a study of the factors that affect the outcome of treatment with a Sonolith Vision lithotripter. Successful SWL was defined as either stone-free status or residual fragments <4 mm at 12 weeks. Logistic regression analysis was performed to assess the factors that predicted treatment outcomes. Potential predictors included the patient's age, shock wave delivery rate, stone volume (SV), mean stone density (MSD), skin-to-stone distance (SSD), and the mean thickness of the three main components along the shock wave path: renal cortical thickness (KT), muscle thickness (MT), and soft-tissue thickness (ST). Results The mean age of the patients was 53.8 years (range, 25-82 years). The overall treatment success rate after one session of SWL was 43.2%. The mean KT, MT, and ST were 26.9, 16.6, and 40.8 mm, respectively. The logistic regression results showed that a slower shock wave delivery rate, smaller SV, a lower MSD, and a thicker KT were found to be significant predictors for successful SWL. SSD, MT, and ST were not predictors of successful treatment. Conclusions Among the main tissue components along the shock wave path, a thicker KT was a favorable factor for successful SWL after adjustment for SV, MSD, and the shock wave delivery rate.","PeriodicalId":17819,"journal":{"name":"Korean Journal of Urology","volume":"56 5","pages":"379-85"},"PeriodicalIF":0.0,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4111/kju.2015.56.5.379","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33294479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease-free survival (DFS) and overall survival (OS) were determined by using a Cox proportional hazards model that included the number of excised lymph nodes, the presence of pathological lymph node metastasis, the anatomical level of positive nodes, the number of positive lymph nodes, lymph node density, and the presence of skip metastasis.Results: The mean number of lymph nodes removed per patient was 29.4±9.3. Lymph node positivity was detected in 85 patients (34.1%). The mean follow-up duration was 44.9±27.4 months (2-93 months). Five-year estimated OS and DFS for the 85 patients were 62.6% and 57%, respectively. Three of 29 lymph node-positive patients (10.3%) had skip metastasis. Only lymph node positivity had a significant effect on 5-year OS and DFS (p<0.001). No difference in OS and DFS was found between the three patients with skip metastasis and other lymph node-positive patients. Other factors related to lymph node status had no significant effect on 5-year OS and DFS.Conclusions: No factors related to lymph node status predict DFS and OS, except for lymph node positivity.

The diagnosis of PC remains controversial owing to overdetection of indolent disease, which leads to overtreatment and subsequent patient harm. mp-MRI has the potential to equilibrate the imbalance between detection and treatment. The limitation of the data for analysis with this new technology is problematic, however. This issue has been compounded by a paradigm shift in clinical practice aimed at utilizing this modality, which has been rolled out in an ad hoc fashion often with commercial motivation. Despite a growing body of literature, pertinent clinical questions remain. For example, can mp-MRI be calibrated to reliably detect biologically significant disease? As with any new technology, objective evaluation of the clinical applications of mp-MRI is essential. The focus of this review was on the evaluation of mp-MRI of the prostate with respect to clinical utility.

PBT was defined as the transfusion of allogeneic red blood cells during RC or postoperative hospitalization.\u0000\u0000\u0000RESULTS\u0000Of all patients, 315 patients (72.9%) received PBT. On multivariate logistic regression analysis, female gender (p=0.015), a lower preoperative hemoglobin level (p=0.003), estimated blood loss>800 mL (p<0.001), and performance of neoadjuvant chemotherapy (p<0.001) were independent risk factors related to requiring perioperative transfusions. The receipt of PBT was associated with increased overall mortality (hazard ratio, 1.91; 95% confidence interval, 1.25-2.94; p=0.003) on univariate analysis, but its association was not confirmed by multivariate analysis (p=0.058).

The primary end point was the histological presence of prostate adenocarcinoma in the biopsy specimen. Outcomes, including treatment methods, survival, and causes of death, were also assessed. Factors associated with the diagnosis of prostate cancer were evaluated by using logistic regression analysis.Results: Patients with prostate cancer were more likely to have higher serum prostate-specific antigen (PSA) (p=0.001) and focal FDG uptake (p=0.036) than were those without. Prostate cancer occurred in 1 of 26 patients (3.8%) with serum PSA<2.5 ng/mL, compared with 40 of 67 patients (59.7%) with serum PSA≥2.5 ng/mL. Multivariable analysis showed that focal lesions (odds ratio [OR], 5.50; p=0.038), age (OR, 1.06; p=0.031), and serum PSA (OR, 1.28; p=0.001) were independent predictors of prostate cancer diagnosis. Most patients with prostate cancer had organ-confined tumors. Of these, 12 (29.3%) underwent radical prostatectomy and 25 (60.9%) received hormone therapy. Of the 11 patients who died, 9 died of primary cancer progression, with only 1 patient dying from prostate cancer.Conclusions: The prevalence of incidental FDG uptake in the prostate was not high, although patients with elevated serum PSA had a higher incidence of prostate cancer. Patients with FDG uptake in the prostate should be secondarily evaluated by measuring serum PSA, with those having high serum PSA undergoing prostate biopsy.","PeriodicalId":17819,"journal":{"name":"Korean Journal of Urology","volume":"56 4","pages":"288-94"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4111/kju.2015.56.4.288","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33097681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed a complete blood count as a part of the diagnostic procedure, and NLR, PLR, MPV, and PLT values were recorded. We compared the patient and control groups in terms of these parameters.
