OBJECTIVE: Atlantal arch defects are rare. Few cadaveric and imaging studies have been reported on the variations of such anomalies. Our goal in this study was to examine the incidence and review the clinical implications of this anomaly. METHODS: A retrospective review of 1,153 neck or cervical spine computed tomography (CT) scans was performed to identify patients with atlantal arch defects. Neck CT scans were performed in 650 patients and cervical spine CT scans were performed in 503 patients

Different urinary symptoms and uroflowmetric parameters were associated with changes in seasons. QOL and IPSS parameters might be worse in cold weather seasons compared with hot weather seasons.

The change in abdominal pressure was correlated with endoscopically-proven obstruction. Our simple modification of the BOOI on the basis of this finding better predicted bladder outlet obstruction and, therefore, should be considered when evaluating BOO in patients with LUTS/BPH.

Purpose: To evaluate ureteral stenting as a negative predictive factor influencing ureteral stone clearance and to estimate the probability of one-session success in shock wave lithotripsy (SWL) patients with a ureteral stone. Materials and Methods: We retrospectively reviewed the medical records of 1,651 patients who underwent their first SWL. Among these patients, 680 had a ureteral stone measuring 4–20 mm and were thus eligible for our study. The 57 patients who underwent ureteral stenting du

Background: To examine the recovery rate of nontuberculous mycobacteria (NTM) from respiratory specimens and the clinical course of NTM pulmonary disease at a 700-bed secondary hospital. Methods: This study analyzed the results of 843 acid-fast bacilli (AFB) culture-positive respiratory specimens from 650 subjects collected between May 2003 and April 2008. In addition, the clinical course of NTM pulmonary disease, diagnosed using criteria established by the American Thoracic Society, was examine

Only mid-PUC was associated with symptom severity in men with LUTS and a small PV. Our findings suggest that mid-PUC could be a potential causal factor of LUTS, and the midportion of the prostatic urethra might play a pivotal role in the process of micturition.

Despite the wide application of prostate-specific antigen-based screening leading to aprofound stage migration in prostate cancer (PC), a significant percentage of men arestill being diagnosed with clinically high-risk disease that requires aggressivetreatment. Optimal management in these patients remains challenging, and strongadvocates for radical prostatectomy (RP), radiotherapy, androgen deprivation therapy,and, increasingly, a multimodal approach abound. Currently, surgery for high-risk PCi

Purpose: Transobturator slings have become an alternative to retropubic slings for the surgical treatment of stress urinary incontinence (SUI).We aimed to compare the efficacy and outcome between transobturator and retropubic mid-urethral sling procedures.Materials and Methods: We reviewed the chart of 186 consecutive women who had sling procedures with a follow-up of at least 1 year from 2001 to 2006.The retropubic sling procedure was perfomed on 76 women assigned to retropubic group.A total 11

Purpose: To evaluate the efficacy of low-dose computed tomography (LDCT) for detectingurinary stones with the use of an iterative reconstruction technique for reducingradiation dose and image noise. Materials and Methods: A total of 101 stones from 69 patients who underwent both conventionalnonenhanced computed tomography (CCT) and LDCT were analyzed. Interpretations were made of the two scans according to stone characteristics (size, volume,location, Hounsfield unit [HU], and skin-to-stone dist

Streptococcus pneumoniae is an infrequent cause of infective endocarditis in the penicillin era. This infection typically follows pneumonia in the setting of chronic alcoholism and may be complicated by meningitis. Only one adult case of pneumococcal endocarditis (PE) has been reported in Korea. We report the case of a 73-year-old woman who suffered from PE complicated by embolic cerebral infarction and meningitis. This is the first Korean case of PE complicated with meningitis. The patient was

Purpose: Complications after prostate biopsy have increased and various causes havebeen reported. Growing evidence of increasing quinolone resistance is of particularconcern. In the current retrospective study, we evaluated the incidence of infectiouscomplications after prostate biopsy and identified the risk factors. Materials and Methods: The study population included 1,195 patients who underwenta prostate biopsy between January 2007 and December 2012 at Chung-Ang UniversityHospital. Cases of

The purpose of this study was to determine whether contemporary active surveillance (AS) protocols could sufficiently discriminate significant from indolent tumors in men with lowrisk prostate cancer. We retrospectively analyzed 312 patients with low-risk prostate cancer treated with radical prostatectomy. After exclusion of patients with fewer than 10 cores taken at biopsy and those who received neo-adjuvant treatment, 205 subjects satisfied the final inclusion criteria. Five widely accepted AS

We report here on a case of persistent proatlantal artery type I with the absence of the right vertebral artery’s first, second and third segments. This rare anomaly was accidentally encountered when performing angiography in a patient with a ruptured aneurysm of the left anterior choroidal artery and an unruptured aneurysm of the right anterior choroidal artery. Both aneurysms were clipped via craniotomy. The angiography showed that the right proatlantal artery type I arose from the right inter
