Right double inferior vena cava with obstructed retrocaval ureter is an extremely rare anomaly with only a few reported cases in the literature. To the best of our knowledge, this is the first case report describing ureteric repair by use of a single-incision laparoscopic technique. In addition, this report addresses the underlying surgical challenges of this repair and provides a brief review of the embryology of this anomaly. The "Santosh Postgraduate Institute ureteric tacking fixation technique" provides ease of end-to-end uretero-ureteric anastomosis in a single-incision laparoscopic surgery.

PURPOSE: To evaluate the predictive role of the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), and platelet count (PLT) in the diagnosis of testicular torsion (TT) and testicular viability following TT. MATERIALS AND METHODS: We analyzed two study groups in this retrospective study: 75 patients with a diagnosis of TT (group 1) and 56 age-matched healthy subjects (group 2). 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. Then, TT patients were divided into two subgroups according to the time elapsed since the onset of symptoms. Subsequently, we evaluated the relationship between the duration of symptoms and these parameters. RESULTS: There were significant differences between groups 1 and 2 in NLR, PLR, and PLT (p<0.001 for all). There was no predictive role of MPV in the diagnosis of TT (p=0.328). We determined significantly high sensitivity and specificity levels for NLR in the prediction of TT diagnosis (84% and 92%, respectively). Furthermore, NLR was significantly related to the duration of symptoms in TT patients (p=0.01). CONCLUSIONS: NLR may be a useful parameter in the diagnosis of TT. Furthermore, NLR may be used as a predictive factor for testicular viability following TT.

Korean Journal of Urology 2015;56(4):318-323
PURPOSE: Testicular microlithiasis (TM) is a relatively rare clinical entity of controversial significance characterized by the existence of hydroxyapatite microliths located in the seminiferous tubules. The aim of this study was to observe the natural course of changes in the calcific density of pediatric TM. MATERIALS AND METHODS: We included a total of 23 TM patients undergoing scrotal ultrasound (US) on at least two occasions from July 1997 to August 2014. We retrospectively analyzed the patient characteristics, clinical manifestations, specific pathological features, and clinical outcomes. We measured the calcified area and compared the calcific density between the initial and final USs. RESULTS: The mean age at diagnosis was 11.3+/-4.6 years, and the follow-up period was 79.1+/-38.8 months (range, 25.4-152.9 months). During the follow-up period, no patients developed testicular cancer. Calcific density on US was increased in the last versus the initial US, but not to a statistically significant degree (3.74%+/-6.0% vs. 3.06%+/-4.38%, respectively, p=0.147). When we defined groups with increased and decreased calcification, we found that diffuse TM was categorized into the increased group to a greater degree than focal TM (10/20 vs. 4/23, respectively, p=0.049). In addition, five of eight cases of cryptorchidism (including two cases of bilateral cryptorchidism) were categorized in the increased calcification group. CONCLUSIONS: Diffuse TM and cryptorchidism tend to increase calcific density. Close observation is therefore recommended for cases of TM combined with cryptorchidism and cases of diffuse TM.

PURPOSE: To investigate the potential benefits of testosterone administration to elderly men (>65 years) with late-onset hypogonadism (LOH) in comparison with younger men and to assess the safety of testosterone administration to elderly men. MATERIALS AND METHODS: A total of 561 hypogonadal men from two registry studies were divided into age groups of < or =65 years (group Y, n=450; range, 32-65 years) and >65 years (group O, n=111; range, 66-84 years). Following an initial 6-week interval, all men were treated with 3-month injections of parenteral testosterone undecanoate for up to 6 years. RESULTS: Over the 6 years, there was a progressive decrease of body weight and waist circumference. Beneficial effects on lipids and other metabolic factors and on psychological and sexual functioning progressed over the first 24 to 42 months and were sustained. Rather than a deterioration, there was an improvement of urinary parameters. Prostate volume and prostate-specific antigen increased moderately. Hematocrit levels increased but remained within safe margins. CONCLUSIONS: The benefits of restoring serum testosterone in men with LOH were not significantly different between men older than 65 years of age and younger men. There were no indications that side effects were more severe in elderly men. The effects on prostate and urinary function and hematocrit were within safe margins. Age itself need not be a contraindication to testosterone treatment of elderly men with LOH.

PURPOSE: We conducted a prospective single-center study to evaluate the possibility of discontinuation of dutasteride after combination therapy with an alpha blocker for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We prospectively treated BPH patients with an alpha blocker and dutasteride (0.5 mg/d). Patients who had been treated with alpha blockers against BPH for more than 2 months were eligible, and 20 patients were included in the study. After 6 months of combination therapy, dutasteride was discontinued. Patients were followed for 12 months after cessation. Prostate volume, intraprostatic architecture determined by transrectal ultrasound, peak urinary flow rate, postvoid residual urine volume, and the serum prostate-specific antigen level were evaluated every 6 months, and the International Prostate Symptom Score and overactive bladder symptom score (OABSS) every 3 months. Patients were allowed to restart dutasteride during the follow-up period according to their desire. RESULTS: Twelve patients (12/20, 60%) restarted the combination therapy from 6 to 12 months into the follow-up period. For patients who restarted dutasteride, the prostate volume and OABSS had increased and worsened after discontinuation, respectively. A visible transition zone with a clear border on transrectal ultrasound at baseline and regrowth of the prostate after discontinuation of dutasteride were risk factors for restarting the therapy (Mann-Whitney U test: p=0.008, p=0.017). CONCLUSIONS: Prostatic enlargement after discontinuation of dutasteride differs among patients. Rapid regrowth of the prostate leads to deterioration of storage symptoms and a tendency to restart dutasteride. Baseline intraprostatic architecture may be a predictive factor for whether the patient is a good candidate for discontinuation.

PURPOSE: The aim of our study was to assess the influence of perioperative blood transfusion (PBT) on survival outcomes following radical cystectomy (RC) and pelvic lymph node dissection (PLND). MATERIALS AND METHODS: We reviewed and analyzed the clinical data of 432 patients who underwent RC for bladder cancer from 1991 to 2012. PBT was defined as the transfusion of allogeneic red blood cells during RC or postoperative hospitalization. RESULTS: Of 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). In transfused patients, a transfusion of >4 packed red blood cell units was an independent predictor of overall survival (p=0.007), but not in cancer specific survival. CONCLUSIONS: Our study was not conclusive to detect a clear association between PBT and survival after RC. However, the efforts should be made to continue limiting the overuse of transfusion especially in patients who are expected to have a high probability of PBT, such as females and those with a low preoperative hemoglobin level and history of neoadjuvant chemotherapy.

PURPOSE: To investigate the prevalence and clinical significance of incidental prostate fluoro-2-deoxyglucose (FDG) uptake and to evaluate its impact on patient management. MATERIALS AND METHODS: Of 47,109 men who underwent FDG positron emission tomography between 2004 and 2014, 1,335 (2.83%) demonstrated incidental FDG uptake in the prostate, with 99 of the latter undergoing prostate biopsy. 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> or =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.

PURPOSE: This study was performed to examine the treatment of erectile dysfunction by use of superparamagnetic iron oxide nanoparticles-labeled human mesenchymal stem cells (SPION-MSCs) transplanted into the cavernous nerve injured cavernosa of rats as monitored by molecular magnetic resonance imaging (MRI). MATERIALS AND METHODS: Eight-week-old male Sprague-Dawley rats were divided into three groups of 10 rats each: group 1, sham operation; group 2, cavernous nerve injury; group 3, SPION-MSC treatment after cavernous nerve injury. Immediately after the cavernous nerve injury in group 3, SPION-MSCs were injected into the cavernous nerve injured cavernosa. Serial T2-weighted MRI was done immediately after injection and at 2 and 4 weeks. Erectile response was assessed by cavernous nerve stimulation at 2 and 4 weeks. RESULTS: Prussian blue staining of SPION-MSCs revealed abundant uptake of SPION in the cytoplasm. After injection of 1x10(6) SPION-MSCs into the cavernosa of rats, T2-weighted MRI showed a clear hypointense signal induced by the injection. The presence of SPION in the corpora cavernosa was confirmed with Prussian blue staining. At 2 and 4 weeks, rats with cavernous nerve injury had significantly lower erectile function than did rats without cavernous nerve injury (p<0.05). The group transplanted with SPION-MSCs showed higher erectile function than did the group without SPION-MSCs (p<0.05). The presence of SPION-MSCs for up to 4 weeks was confirmed by MRI imaging and Prussian blue staining in the corpus cavernosa. CONCLUSIONS: Transplanted SPION-MSCs existed for up to 4 weeks in the cavernous nerve injured cavernosa of rats. Erectile dysfunction recovered and could be monitored by MRI.

9.How much progress has been made in journal metrics two years after the citation analysis of the Korean Journal of Urology?.
Korean Journal of Urology 2015;56(4):276-279
PURPOSE: In April 2013, the journal metrics of the Korean Journal of Urology (KJU) were reported. That report showed tremendous improvement from the point of view of journal metrics. Two years later, the same metrics were reanalyzed to determine the present position of the KJU among the international journals in the Web of Science. MATERIALS AND METHODS: I analyzed journal metrics of the KJU such as impact factor, total citations, and h-index by use of the same methods as in the previous report. RESULTS: Total citations in the Web of Science were 332 in 2012, 439 in 2013, and 578 in 2014. Manually calculated impact factors from 2012 to 2014 were 0.770, 0.824, and 0.751, respectively. There was an increase in the h-index from 8 in 2012 to 11 in February 2015. Editorial board members were from 15 countries in 2014. Authors of KJU articles were from 21 countries in 2014. CONCLUSIONS: During 2 years, remarkable progress was made in KJU's citation indicators and in the diversity of the authors' and editorial board members' countries.

Korean Journal of Urology 2015;56(4):266-275
Lower urinary tract dysfunction-such as urinary incontinence (UI), detrusor overactivity, and benign prostatic hyperplasia-is prevalent in elderly persons. These conditions can interfere with daily life and normal functioning and lead to negative effects on health-related quality of life. UI is one of the most common urologic conditions but is poorly understood elderly persons. The overall prevalence of UI increases with age in both men and women. Elderly persons often neglect UI or dismiss it as part of the normal aging process. However, UI can have significant negative effects on self-esteem and has been associated with increased rates of depression. UI also affects quality of life and activities of daily living. Although UI is more common in elderly than in younger persons, it should not be considered a normal part of aging. UI is abnormal at any age. The goal of this review is to provide an overview of the cause, classification, evaluation, and management of geriatric lower urinary tract dysfunction.
