Leriche syndrome is a chronic disorder mostly in male and is a specific symptom complex due to thrombotic obliteration of the aortic bifurcation as result of an atherosclerotic change. The symptoms include 1) extreme liability to fatigue of both lower limbs; 2) symmetric atrophy of both lower limbs; 3) pallor of the legs and feets; 4) inability to maintain stable erection. There are several methods for surgical management of this disorder; 1) thromboendarterectomy with or without sympathectomy; 2) aortoiliac bypass graft; 3) aortofemoral bypass graft. Here we report a case of Leriche syndrome which was successfully managed with aortobifemoral bypass graft with Dacron and reviewed literatures on it briefly.

OBJECTIVE: In a rabbit model using hysteroscopy-guided inoculation of E.coli with antibiotic administration, we determine the effects of persistent intrauterine infection on perinatal outcome including fetal death, congenital sepsis, and abnormal fetal-placental growth and amniotic fluid volume in live fetuses. METHODS: Rabbits with timed pregnancies underwent hysteroscopy at 20 to 21 days of gestation(70%). Animals were inoculated with E. coli (0.2 ml containing 10 cfu/ml) and administered ampicillin-sulbactam(100 mg/kg/day; Unasyn; Pfizer) every 8 hours beginning 30 minutes after microbial inoculation until they were killed 5 days after hysteroscopy. In the first study, the following outcome parameters were evaluated between fetuses with and without pe#rsistent intrauterine infection: fetal survival, congenital sepsis, maternal morbidity, and placental pathology. In second study was performed in 16 rabbits having only both live fetuses with and without persistent intrauterine infection in a rabbit simultaneously. We evaluate the effects of persistent intrauterine infection on fetal-placental weight and amniotic fluid volume in live fetuses. RESULTS: 1) Fetuses with persistent intrauterine infection had significantly fewer live fetuses, more positive cord blood cultures than those without (live fetuses: 44% vs 82%, p<0.000001; positive cord blood cultures: 44% vs 3%, p<0.000001, respectively; Fishers exact test). However the rates of maternal morbidity and placental inflammatory lesions were similar between the two groups. 2) The placental weight and amniotic fluid volume were significantly less in live fetuses with than in those without persistent intrauterine infection. Moreover the fetal weight was decreased in live fetuses with persistent intrauterine infection, but it was not statistically significant(placental weight: p<0.05; amniotic fluid volume: p<0.05; fetal weight: p 0.051, respectively; Wilcoxon matched-pairs signed ranks test). CONCLUSION: Fetal complications including fetal death, congenital sepsis, and decreased fetal-placental weight and amniotic fluid volume wae produced in utero when pasistent intrauterine infection was present with antibiotics administration after inoculstion of E. coli. Therefore, when treating with antibiotics in intrauterine infection, it is needed to observe and monitar the presence of persistent intrauterine infection, and if it is peristent, delivery may be considered for the improvement of pregnancy outcome.

4.Clinical Factors Associated With the Feeling of Incomplete Bladder Emptying in Women With Little Postvoided Residue
International Neurourology Journal 2020;24(2):172-179
Purpose:
To investigate the clinical factors associated with the feeling of incomplete bladder emptying in female patients with lower urinary tract symptoms (LUTS).
Methods:
Records were obtained from a prospectively maintained database for 353 female patients without a history of treatment for LUTS. Patients with comorbidities that may affect voiding function and with postvoid residual (PVR) volume >20 mL or PVR volume-to-bladder capacity ratio of >10% were excluded. Finally, 211 patients were eligible for the study.
Results:
Patients were stratified according to the severity of the feeling of incomplete emptying: non-severe group (n=147, 69.7%) and severe group (n=64, 30.3%). The severe group showed longer time to maximum flow rate (Qmax) and greater total overactive bladder symptom score (OABSS). No differences in age, PVR volume, and diagnosis of overactive bladder (OAB) were found between the 2 severity groups. Multivariable analysis identified the severity of the feeling of incomplete emptying to be significantly associated with time to Qmax and minimum volume of voids. Time to Qmax was identified as a significant predictor of severe symptoms in women with OAB. In addition, the feeling of incomplete emptying, total OABSS, and minimum volume of voids were significantly associated with quality of life.
Conclusions
Female patients with the feeling of incomplete emptying who have insignificant PVR volume exhibited severe voiding symptoms and low quality of life. The treatment strategy should be focused on improving the minimum volume of voids and shortening the time to Qmax.

Congenital dermal sinuses result from a failure of separation of the cutaneous epithelial ectoderm from the neuroepithelial ectoderm along the dorsum of the embroy during the first month of intra-uterine life. These sinus tracts can occur at any level of the cerebro-spinal axis, but are located predominantly in the occipital and lumbosacral regions and occasional cases involving the cervical and thoracic regions. The dermal sinus tract is lined by stratified squamous epithelium and extends from the surface through the deeper tissues into the cranial or spinal cavity, usually ending on the dura or within the dura in conjunction with a terminal epidermoid or dermoid cyst. An intra-medullary epidermoid or dermoid with a dermal sinus is an unusual association. We have been able to find a previously reported coincidence of these malformations although there are many definitive papers on these uncommon entities. We are experienced in one case who are 14 months old boy with a intra-medullary dermoid cyst associated with a congenital dermal sinus at the T4 level, and reviewed related reports.

PURPOSE: Stone size and location are generally considered the most important factors associated with spontaneous ureter stone passage (SSP). Several parameters related to inflammatory changes have been identified as predictors associated with SSP. Our aim was to investigate the predictive role of neutrophil-to-lymphocyte ratio (NLR) for SSP. MATERIALS AND METHODS: A retrospective review was performed on 131 patients who were referred to the urology outpatient clinic and diagnosed with unilateral ureteral stones at our emergency department between July 2016 and December 2016. The presence of ureteral stones was confirmed with non-contrast-enhanced computed tomography (NCCT) for all patients. SSP was confirmed with either the patient collecting the stone during urination or by NCCT performed at 3 weeks from the first stone episode. Physical examination, urinalysis, complete blood count, serum chemistry and inflammatory markers, plain radiographs, and NCCT at initial presentation were reviewed to analyze predictors of future SSP. RESULTS: Of 113 patients included for analysis, 90 (79.6%) passed their stones spontaneously. The SSP rates within 3 weeks according to the stone's size (5–10 mm and ≤5 mm) were 62.2% and 88.2%, respectively. A lower stone location [odds ratio (OR), 11.54; p=0.001], smaller stone size (≤5 mm) (OR, 8.16; p=0.001), and NLR (<2.3) (OR, 9.03; p=0.003) were independent predictors of SSP. CONCLUSION: Low NLR (<2.3) may predict SSP in patients with ureter stones ×1.0 cm in size. Our results suggest that ureteral inflammation plays an important role in SSP. Early intervention may be considered for patients presenting with high NLR (≥2.3).

OBJECTIVES: Our purpose was (1) to determine whether amniotic fluid concentrations of interleukin-6 are of value in the diagnosis of histologic chorioamnionitis of preterm placenta and in the prediction of significant perinatal morbidity and mortality in patients with preterm premature rupture of membranes and (2) to compare the diagnostic performance of amniotic fluid interleukin-6 with that of amniotic fluid microbial culture for these outcome variables. METHOD: The relation among placental histologic finding, perinatal outcome, amniotic fluid culture, and amniotic fluid interleukin-6 concentrations were examined in 65 patients with preterm premature rupture of membranes who delivered preterm neonates within 72 hours after transabdominal amniocentesis. Interleukin-6 level was determined by enzyme-linked immunosorbent assay. Receiver-operator characteristic curve, Mann-Whitney U test, and Fisher's exact test were used for analysis. RESULTS: 1) Patients with acute histologic chorioamnionitis had significantly higher median amniotic fluid interleukin-6 concentrations than those without histologic chorioamnionitis (median 12.6 ng/ml, range 0.03 to 142.2 ng/ml vs median 0.5 ng/ml, range 0.03 to 16 ng/ml; P < 0.0001). 2) Amniotic fluid having interleukin-6 concentrations higher than 3.2 ng/ml had a sensitivity of 78% (35/45) and specificity of 95% (19/20) in the diagnosis of acute histologic chorioamnionitis and sensitivity of 74% (25/34) and specificity of 65% (20/31) in the prediction of significant neonatal morbidity and mortality. 3) These sensitivities were significantly higher than those of amniotic fluid culture, but there were no significant difference in specificities between amniotic fluid interleukin-6 and culture (histologic chorioamnionitis: 78% vs 51%, p<0.01; significant neonatal morbidity and mortality: 74% vs 47%, p<0.01, respectively). CONCLUSIONS: Test of amniotic fluid interleukin-6 is of value and more sensitive than amniotic fluid culture for the antenatal diagnosis of histologic chorioamnionitis and for the prediction of perinatal outcome in patients with preterm premature rupture of membranes.

PURPOSE: Postoperative urinary retention (POUR) is a common complication after spinal surgery. However, no clear definition of POUR currently exists, and no studies have evaluated the management of POUR. We aimed to investigate the prognostic factors for eventual POUR-free status in spinal surgery patients. METHODS: The records of patients who received a urologic consultation for POUR from January 2015 to December 2016 were reviewed. POUR-free status was defined as a voiding volume (VV) >100 mL and a VV ratio >50%. Patients with an indwelling Foley catheter and those with any postoperative complications were excluded. The patients were divided into 2 groups according to the primary management method (Foley catheterization [FC] or intermittent catheterization [IC]). RESULTS: In total, 205 patients (median age, 70.6 years) were evaluated. Significant prognostic factors for eventual POUR-free status were intraoperative FC, previous spinal surgery, operative level (L3–5), lumbar fusion, and total volume (TV) at the time of POUR. Bladder training and medication did not reduce the time to POUR-free status. In patients who underwent FC, the duration of indwelling FC was a significant prognostic factor for POUR-free status. In a subanalysis, the TV (≥500 mL) and VV ratio at the time of POUR were significant prognostic factors for POUR-free status after primary management. Among the patients who achieved a POUR-free status, 8 (6.4%) experienced recurrent POUR. The VV ratio (<62.0%) was the only predictor of recurrent POUR. CONCLUSIONS: The criterion of POUR-free status is useful after spinal surgery. IC and FC were similar in their efficacy for the management of these patients.

Purpose:
To identify the indication for recommending prebiopsy magnetic resonance imaging (MRI) to prevent prostate cancer missed diagnoses in cases without prebiopsy MRI.
Materials and Methods:
Between January 2017 and September 2020, 585 patients suspected with prostate cancer underwent prostate biopsy after MRI. For patients with visible lesions, MRI-targeted biopsy using an image-based fusion program was performed in addition to the 12- core systematic biopsy. Patients for whom MRI was performed in other institutions (n=4) and patients who underwent target biopsy alone (n=7) were excluded.
Results:
Of 574 patients (median prostate-specific antigen [PSA] level, 6.88 ng/mL; mean age, 68.2 years), 342 (59.6%) were diagnosed with prostate cancer (visible lesions=312/449 [69.5%]; nonvisible lesions=30/123 [24.0%]). The detection rates of visible lesions stratified using the Prostate Imaging Reporting and Data System score (3 vs. 4 vs. 5) were 30.9% (54 of 175), 61.2% (150 of 245), and 90.1% (127 of 141), respectively. Multivariate analysis showed that PSA density was a significant factor for presence of visible lesions, prostate cancer, and significant prostate cancer diagnosis. Among patients with positive lesions, 27 (8.2%) were diagnosed with prostate cancer concomitant with negative systematic biopsy results. A PSA density of 0.15 ng/mL/cm3 was identified as the significant cutoff value for predicting positive target biopsy in groups with negative systematic biopsy. Sixty of the negative target lesions (26.1%) were diagnosed using systematic biopsy.
Conclusions
To maximize cancer detection rates, both targeted and systematic biopsies should be implemented. PSA density was identified as a useful factor for recommending prebiopsy MRI to patients suspected with prostate cancer.
