Objective: To evaluate the safety and feasibility of prostatic artery embolization (PAE) via transradial access (TRA) compared with transfemoral access (TFA). Materials and Methods: This retrospective study included 53 consecutive men with lower urinary tract symptoms (LUTS) who underwent PAE between September 2018 and September 2021. Thirty-one patients (mean age ± standard deviation: 70.6 ± 8.4 years) were treated with TFA, including 14 patients treated before adopting TRA. Since December 2019, TRA has also been attempted with the procedure's selection criteria of patent carpal circulation and a height ≤ 172 cm, with 22 patients treated via TRA (69.1 ± 9.6 years). Parameters of technical success (defined as successful bilateral embolization), clinical success (defined as LUTS improvement), procedural time, radiation dose, and adverse events were compared between the two groups using the Fisher's exact test, independent sample t test, Wilcoxon signed-rank test, or Mann-Whitney test. Results: All patients received at least one-side PAE. Technical success of PAE was achieved in most patients (TRA, 21/22; TFA, 30/31; p > 0.999). No technical problem-related conversion from TRA to TFA occurred. The clinical success rate was 85% (11/13) in patients with TRA, and 89% (16/18) in patients with TFA for follow-up > 2 weeks post-PAE (median, 3 months) (p > 0.999). The median procedure time was similar in both groups (TRA, 81 minutes vs. TFA, 94 minutes; p = 0.570). No significant dose differences were found between the TRA and TFA groups in the dose-area product (median Gycm², 95 [range, 44-255] for TRA and 84 [34-255] for TFA; p = 0.678) or cumulative air kerma (median mGy, 609 [236-1584] for TRA and 634 [217-1594] for TFA; p = 0.551). No major adverse events occurred in either of the groups. Conclusion: PAE via TRA is a safe and feasible method comparable to conventional TFA. It can be safely implemented by selecting patients with patent carpal circulation and adequate height.

Tuberculous epididymo-orchitis, a rare form of extrapulmonary tuberculosis, results from hematogenous dissemination or retrograde extension from the lower urinary tract. Herein, we studied the case of a 22-year-old male patient who presented with refractory left scrotal pain and inflammation. The patient also complained of multifocal pain involving the right buttock, posterior thigh, and right wrist, without trauma history. The patient was diagnosed with multifocal tuberculosis by sputum AFB study and right sacroiliac joint biopsy.

Vulvar agenesis in an eight-month-old toy poodle dog is described. Urinary incontinence and dysuria were the main clinical signs. The morphology of the urogenital system was assessed with contrast radiography. The constructers of lower urinary tract and reproductive system except for the vulva were normal features. Through episiostomy, a perineal stoma, resembling a vulva, was created, resulting in complete resolution of the clinical signs.

The aim of this study was to implement the system that could evaluate the function of urinary tract with noninvasive and comfort methods. There for in this study hardware device and computer software have been developed that enables the analysis of the urine flow rate and vesical pressure signal measured during voiding. These signals were recorded simultaneously and transmitted to the PC. For the measurement system evaluation, the model system for the lower urinary system of men was designed. From the evaluation of the model system, vesical pressure was correlated with the occlusion degree. In a pilot study on 5 male subjects, means of standard deviation was 1.06, average error rate was 2.09 and coefficient variation was 2.09.

Purpose: We evaluated the long-term results of endoscopic Deflux$^{(R)}$ injection for treating vesicoureteral reflux (VUR) in children. Methods: Between September 2004 and September 2014, 243 children (137 boys and 106 girls) with a mean age of 53 months underwent Deflux$^{(R)}$ injection. Our clinical protocol included radionuclide voiding cystography (RNC) at postoperative 3 months, 1 year and 3 years to assess the VUR resolution. Results: The cure rates at 3 months, 1 year, and 3 years by patients were 70.8%, 64.3%, and 65.6% for the total patients and 79.2%, 75.2%, and 76.4%, for the ureters, respectively. The recurrence rate of postoperative febrile urinary tract infection (UTI) was 20% in patients without VUR at postoperative 1 year. Twenty patients undergoing ureteroneocystostomy (UNC) significantly had younger age (P=0.003), higher VUR grade (P<0.001), and lower success rates of Deflux$^{(R)}$ injection (P<0.05). On univariate analysis, older age (P=0.014) and lower grade of VUR (P=0.031) were the significant predictors of a successful outcome. But there was none on multivariate analysis. Younger age, especially age of 0-12 month-old, was the only significant predictor of postoperative febrile UTI recurrence on both univariate and multivariate analysis. Conclusion: Deflux$^{(R)}$ injection is efficacious with a low complication rate for the anti-reflux procedure in children. There is low recurrence rate of UTI though VUR persists, and high probability of no VUR at 3 years if no VUR at 1 year. It is recommendable not to perform follow-up RNC at 3 years routinely if no VUR at 1 year.

Polyps of the male urethra are relatively uncommon lesions. They usually arise from the prostatic urethra mostly verumontanum or Just lateral to the verumontanum. Posterior urethral polyp often presents with hematuria, hemospermia and sometimes lower urinary tract obstruction. We recently experienced a pedunculated prostatic urethral polyp in a 63-year-old man who complained of gross total hematuria and difficult micturition for several years. On rectal examination the prostate was slightly enlarged with normal consistency. Excretory urogram showed a round filling defect in the right side of the bladder neck measuring about $2{\times}2cm.$ in size. Cystourethroscopy revealed trabeculation of the vesical wall, mild bilateral prostatic hypertrophy and a round cystic mass with a long stalk arising from the prostatic floor 1 cm. Proximal to the verumontanum which caused ball-valve obstruction in the bladder neck. This pedunculated polypoid mass was then resected at its base with resectoscope and was removed transurethrally using Lowsley's grasping forceps. The specimen was proved as fibrous polyp histologically.

Since attaining middle age, many patients suffer from the post-micturition dribble (PMD) syndrome but do not receive proper treatment. This is because the etiology and treatment mechanisms of PMD differ from conventional lower urinary tract symptoms. Several pathophysiologies have been proposed, but the mechanisms we observed are the weakening of the bulbocavernosus muscle and dilation of the urethra due to atrophy of the cavernosal tissue. This study investigates the mechanism of PMD by observing anatomical changes in the corpus cavernosum and urethra. SD male rats were categorized by age into the young rats group (8 weeks old) and the old rats group (24 months or more). The ratio area of the bulbous urethra and corpus cavernosum to the total penis was statistically significant between both groups (P<0.05). Significant differences were obtained between the two groups for restored smooth muscle contents and several other parameters related to PMD mechanisms (nNOS, α-SMA) (P<0.05). The changes in size and parameters of the urethra and corpus cavernosum in young and old rats were confirmed. The results from this study are expected to contribute to the study of PMD in the future.

Purpose: This study was carried out to evaluate the efficacy of intravaginal pelvic floor electrical stimulation (FES) therapy on bladder irritability symptoms in stress urinary incontinent women. Materials and Methods: The evaluation before and after treatment included the Blaivas's female Bladder Questionnaire, the quality of life questionnaires and the overall satisfaction with present voiding state using visual analogue test (VAT). All patient were treated for 20 minutes, twice a week for 6 weeks, using a new intravaginal electrical stimulator with microchip (PIC16C74). Results: After the FES therapy, the overall success rate of the SUI was 50.4.% at 9 months. The bladder irritability symptoms such as frequency, nocturia, urgency, residual urine sensation and lower abdominal discomfort were improved. In particular, the symptoms of frequency, urge incontinence, dysuria were significantly improved after the FES therapy at 9 months. The VAT score of the overall satisfaction with the present voiding state was significantly lower after the FES therapy. 73.7% of patients were satisfied with the FES therapy and complications such as hemorrhage, vaginitis, urinary tract infection and pain were not encountered. Conclusion: These results suggest that FES therapy with microchip improves some bladder irritability in SUI women. Therefore, electrical stimulation therapy should be considered as a first line therapy in SUI women with bladder irritability symptoms.

Benign prostatic hyperplasia (BPH) is a highly prevalent, age-related disorder in men which place a considerable burden on health care resources worldwide. While BPH and hypertension are apparently diverse disease processes, they have some features in common(e.g. underlying etiology of the sympathetic nervous system). The purpose of this study is to estimate the prevalence of lower urinary tract symptoms using I-PSS(international prostate symptom score) and to investigate the association of hypertension with I-PSS. This study was carried out to 390 men(40~86 year old) at 3 Myun in Chungju City from July to August, 1997. Subjects answered on questionnaire for I-PSS and were checked age, education, marital status, annual income, blood pressure. The mean age of subjects was 59.8 year old. The mean of I-PSS were increased by age decades(40~49, 50~59, 60~69, 70~86) and it's scores were 4.4, 7.0, 8.2, 12.3 respectively. Strong correlations were observed between the I-PSS and the QUL(quality of life)(P=0.0001). I-PSS(mean-value) were 7.85 in hypertensive group and 8.39 in normotensive group but there was no statistically significance between the two groups(P>0.05). The proportion of mean scoring greater than 8 was 42.5%. There have been reports of association between lower urinary tract symptoms and hypertension, but there was no consistent suggestion that such an association could be casual. The need for high-quality epidemiological information and consequent increased prospects for prevention is obvious.

Purpose: This study aimed to describe bladder dysfunction in elderly women such as frequency, nocturia, and residual urine. Methods: One hundred elderly women aged 60 and over. The Bristol Female Lower Urinary Symptoms (BFLUT) was used to evaluate the bladder function and to measure the residual urine amount by using a bladder scanner. Data was analyzed with the differences between voiding dysfunction by age group and life habits by t-test, ANOVA and correlation by Pearson correlation coefficient. Results: the mean daytime frequency was 6.8 times and night-time frequency 2.7 times. Sixty three percent of subjects had urgency and 41% had urgent incontinence. Over half of subjects had problem in voiding function. There were significant differences in frequency by age groups and constipation, but not in daytime frequency and residual urine. Lastly, there were significant positive relations between daytime frequency and night-time frequency. Also results indicate that more frequency in daytime equaled to a less residual urine amount. Conclusion: We know many elderly women have lower urinary tract symptoms. Specially women over 75 years have more daytime frequency and night-time frequency. This suggests further research needed in order to understand the relation of voiding patterns and life habits and its influence on quality of life.
