RESUMEN
Purpose@#We evaluated the change in patient quality of life after the use of a hydrophilic-coated catheter (SpeediCath) in adults requiring intermittent catheterization (IC). @*Methods@#This was a multicenter, open-label, observational study using the Patient Perception of Intermittent Catheterization (PPIC) questionnaire and the Intermittent Self-Catheterization questionnaire (ISC-Q) and safety at 12 and 24 weeks in adult patients who had already used other type of catheters prior to switching to SpeediCath or in patients undergoing self-IC for the first time for any reason. @*Results@#Among a total of 360 subjects, 215 (59.7%) were women, and the mean age was 62.0±13.2 years. At 24 weeks, the satisfaction rate after using SpeediCath was 84.1%, and 80% of patients responded that they could easily perform IC. In total, 81.6% of patients were willing to continue using SpeediCath. The mean ISC-Q score was 54.90±18.65 at 24 weeks. Men found less interference in their daily life by performing IC than women and found it easier to handle the catheter before it was inserted into the urethra. At week 12, the mean change in ISC-Q was significantly greater in patients <65 years (20.24±23.55) than in those ≥65 years (7.57±27.70, P=0.049), but there was no difference at 24 weeks. The most common adverse events were urinary tract infection in 9.72%, gross hematuria in 2.78%, and urethral pain in 1.39%. @*Conclusions@#The use of a SpeediCath provided good quality of life for patients who needed self-IC regardless of age or sex.
RESUMEN
PURPOSE: To compare the clinical efficacy of anticholinergics for managing diabetes mellitus-associated overactive bladder (DM OAB) versus idiopathic overactive bladder (OAB) in Korean women. METHODS: We conducted a multicenter, prospective, parallel-group, open-label, 12-week study. Women (20–65 years old) with OAB symptoms for over 3 months were assigned to the DM OAB and idiopathic OAB groups. Changes in the Overactive Bladder Symptom Score (OABSS), urgency, urinary urgency incontinence, nocturia, daytime frequency according to a voiding diary, uroflowmetry, and postvoid residual urine volume (PVR) at the first visit (V1), week 4 (V2), and week 12 (V3) were compared. RESULTS: No significant difference was found between the baseline patient characteristics of the DM OAB and idiopathic OAB groups. Treatment with solifenacin was associated with improvements in urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and the total OABSS between V1 and V2 and between V1 and V3. Moreover, a significant improvement in urgency and urge incontinence was found between V2 and V3 in the DM OAB group. However, no significant changes were found in any other parameters. There were no significant differences between the DM OAB group and the idiopathic OAB group except for urgency and urge incontinence at V2 (3.71 vs. 2.28 and 0.47 vs. 0.32, respectively). CONCLUSIONS: The patients who received solifenacin demonstrated improved urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and total OABSS. Management with solifenacin was equally effective for both DM-related OAB and idiopathic OAB.

PURPOSE: Complaints from spinal cord injury (SCI) patients are typically related to physical disability affecting activities of daily life. However, difficulties with voiding and defecation and/or sexual function can also be major concerns. The general population and even physicians are generally unaware of these complaints; therefore, this study focuses on surveying SCI patients regarding challenges that are faced in daily life. METHODS: A questionnaire was administered randomly and anonymously to SCI patients who visited the Korea Spinal Cord Injury Association and several rehabilitation hospitals in the Republic of Korea in 2013. All participants gave their consent prior to filling out the questionnaire. RESULTS: A total of 299 patients answered the questionnaire; the male to female ratio was 5.8:1 and common vectors for injury were motor vehicle accidents, industrial accidents, and falling down. Of the 169 patients who answered the ‘most troublesome’ and ‘wish would improve’ complaints questionnaire properly, urinary problems were most common, specifically incontinence and urinary tract infection. Among all patients, 67% were using clean intermittent catheterization, 63% were taking voiding-related medications, 83% had sexual desires, and among the 122 patients who did not have offspring, 27% had future plans for children. CONCLUSIONS: From this questionnaire, we discovered that SCI patients in the South Korea suffer not only from physical disability but also many other quality-of-life-related problems. When managing SCI patients, physicians should show greater concern and educate patients about problems related to voiding and sexual activity, rather than just physical disability.

PURPOSE: In this study, we compared the treatment outcomes for an alpha-blocker between 2 groups of men, one with high sympathetic activity (HSA) and another with low sympathetic activity (LSA) or normal sympathetic activity. METHODS: A total of 159 men (> or =50 years of age) with lower urinary tract symptoms resulting from benign prostatic hyperplasia were analyzed. We assigned patients to groups according to their sympathetic activity, which was evaluated by heart ratevariability measurements. HSA was defined as a low frequency/high frequency ratio greater than 1.6. All patients received 10mg of alfuzosin once a day for 12 weeks. The primary end point was a change in the total International Prostate SymptomScore (IPSS) at 12 weeks from baseline. RESULTS: Sixty-seven men were assigned to the HSA group and 92 men were assigned to the LSA group. The baseline characteristics were not significantly different between the 2 groups, and the response to alfuzosin was good in both groups. Themean total IPSS change was not different between the groups. Both groups were not significantly different with respect to the changes in maximal flow rate, IPSS voiding or storage symptom subscores, quality of life, and rates of adverse drug events. TheHSA group showed a similar willingness to continue treatment compared to the LSA group, although their treatment satisfaction rating was lower. CONCLUSIONS: The therapeutic effects of alfuzosin did not differ in regards to the differences in sympathetic activity, but treatment satisfaction ratings were lower in the HSA group.

PURPOSE: The aims of this study were to investigate the efficacy of combining the systematized behavioral modification program (SBMP) with desmopressin therapy and to compare this with desmopressin monotherapy in the treatment of nocturnal polyuria (NPU). METHODS: Patients were randomized at 8 centers to receive desmopressin monotherapy (group A) or combination therapy, comprising desmopressin and the SBMP (group B). Nocturia was defined as an average of 2 or more nightly voids. The primary endpoint was a change in the mean number of nocturnal voids from baseline during the 3-month treatment period. The secondary endpoints were changes in the bladder diary parameters and questionnaires scores, and improvements in self-perception for nocturia. RESULTS: A total of 200 patients were screened and 76 were excluded from the study, because they failed the screening process. A total of 124 patients were randomized to receive treatment, with group A comprising 68 patients and group B comprising 56 patients. The patients' characteristics were similar between the groups. Nocturnal voids showed a greater decline in group B (-1.5) compared with group A (-1.2), a difference that was not statistically significant. Significant differences were observed between groups A and B with respect to the NPU index (0.37 vs. 0.29, P=0.028), the change in the maximal bladder capacity (-41.3 mL vs. 13.3 mL, P<0.001), and the rate of patients lost to follow up (10.3% [7/68] vs. 0% [0/56], P=0.016). Self-perception for nocturia significantly improved in both groups. CONCLUSIONS: Combination treatment did not have any additional benefits in relation to reducing nocturnal voids in patients with NPU; however, combination therapy is helpful because it increases the maximal bladder capacity and decreases the NPI. Furthermore, combination therapy increased the persistence of desmopressin in patients with NPU.

PURPOSE: Nationwide database regarding stress urinary incontinence (SUI) is important for evaluating treatment patterns for SUI and for establishing appropriate national policies regarding SUI management. The purpose of this present study was to investigate surgical treatment patterns for women with SUI and analyze the current status of SUI management in Korea by using a nationwide database. METHODS: Data used for investigating the surgical trends and changes in Korea were retrieved from the Health Insurance Review & Assessment Service from 2008 to 2011. RESULTS: The number of surgical cases of SUI decreased continuously from 2008 to 2011. The proportion of transvaginal surgery using a midurethral sling increased continuously. Sling procedures were most commonly performed for women in their 40s followed by women in their 50s. Transvaginal surgery using a single sling or a readjustable sling was performed from 5.6% to 6.1%, which showed no significant change in the number of surgical cases. CONCLUSIONS: There is a growing need for an appropriate national welfare policy and budget to care for aged and super-aged women in Korea. The early detection and intervention of silent SUI should be actively considered as an important preventive strategy to improve the quality of life in younger women.

PURPOSE: In this study, we examined the difference in the treatment efficacy depending on the sympathetic activity in men with lower urinary tract symptoms (LUTS). METHODS: In the current single-center, retrospective study, we evaluated a total of 66 male patients aged 40-70 years of age, presenting with LUTS, whose International Prostate Symptom Score (IPSS) exceeded 8 points. They had a past 3-month history of taking alfuzosin XL, and their heart rate variability (HRV) was measured before and after the treatment. In addition, we also recruited 39 healthy volunteers who visited a health promotion center for a regular medical check-up. They were aged between 40 and 70 years and had an IPSS of <8 points. We divided the patients with LUTS into two groups: the groups A and B, based on a low frequency/high frequency (LF/HF) ratio of 1.7, which was the mean value of the LF/HF ratio in the healthy volunteers. After a 3-month treatment with alfuzosin XL, we compared treatment outcomes, based on the IPSS and peak urine flow rate, between the two groups. RESULTS: A 3-month treatment with alfuzosin XL, comprising the measurement of the HRV, was performed for the 23 patients of the group A (23/38) and 17 of the group B (17/28). After a 3-month treatment with alfuzosin XL, total IPSS and IPSS questionnaire 2 and 5 were significantly lower in the group A as compared with the group B. But this was not seen in the group B. Furthermore, there were no significant differences in other parameters, such as maximal flow rate and IPSS storage subscore, between the two groups. CONCLUSIONS: Our results indicate that the treatment efficacy was lower in patients with sympathetic hyperactivity as compared with those with sympathetic hypoactivity. Thus, our results will provide a basis for further studies to clarify causes of LUTS in a clinical setting.

PURPOSE: To investigate whether hospitalization influences serum prostate-specific antigen (PSA) values. MATERIALS AND METHODS: Transrectal ultrasound-guided prostate biopsies were performed for detecting prostate cancer in 2,017 patients between February 2001 and April 2011 at Ajou University Hospital. Of those patients, 416 patients who were hospitalized for prostate biopsies, whose serum PSA values were measured at the outpatient department within 1 month of admission and also just after admission, and who had negative prostate biopsy results were included in the present study. We retrospectively reviewed the data of the 416 patients and compared the serum PSA values measured in the outpatient department with those measured during hospitalization. RESULTS: Among all 416 patients, the interval between the two PSA measurements was 22.2 days (range, 3 to 30 days) and the prostate size measured by transrectal ultrasonography was 53.63 mL (range, 12.8 to 197.9 mL). Among all patients, mean serum PSA levels measured during hospitalization were significantly lower than those measured in the outpatient department (6.69 ng/mL vs. 8.01 ng/mL, p<0.001). When stratified according to age, the presence or absence of chronic prostatitis in the biopsy pathology, serum PSA levels, and prostate size, the serum PSA levels measured during hospitalization were significantly lower than those measured in the outpatient department in all subgroups, except in cases aged 20 to 39 years and those with PSA <4 ng/mL, in whom no significant differences were shown. CONCLUSIONS: Hospitalization decreases serum PSA values compared with those measured on an outpatient basis in patients with benign prostatic diseases. Therefore, serum PSA values should be checked on an outpatient basis for serial monitoring.

PURPOSE: Thanks to advancements in surgical techniques and instruments, many surgical modalities have been developed to replace transurethral resection of the prostate (TURP). However, TURP remains the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH). We conducted a meta-analysis on the efficacy and safety of minimally invasive surgical therapies for BPH compared with TURP. METHODS: This meta-analysis used a Medline search assessing the period from 1997 to 2011. A total of 784 randomized controlled trials were identified in an electronic search. Among the 784 articles, 36 randomized controlled trials that provided the highest level of evidence (level 1b) were included in the meta-analysis. We also conducted a quality analysis of selected articles. RESULTS: Only 2 articles (5.56%) were assessed as having a low risk of bias by use of the Cochrane collaboration risk of bias tool. On the other hand, by use of the Jadad scale, there were 26 high-quality articles (72.22%). Furthermore, 28 articles (77.78%) were assessed as high-quality articles by use of the van Tulder scale. Holmium laser enucleation of the prostate (HoLEP) showed the highest reduction of the International Prostate Symptom Score compared with TURP (P<0.0001). Bipolar TURP, bipolar transurethral vaporization of the prostate, HoLEP, and open prostatectomy showed superior outcome in postvoid residual urine volume and maximum flow rate. The intraoperative complications of the minimally invasive surgeries had no statistically significant inferior outcomes compared with TURP. Also, there were no statistically significant differences in any of the modalities compared with TURP. CONCLUSIONS: The selection of an appropriate surgical modality for BPH should be assessed by fully understanding each patient's clinical conditions.

PURPOSE: Heart rate variability (HRV) is a tool used to measure autonomic nervous function; however, there is no evidence that it can be used to define sympathetic hyperactivity in men with lower urinary tract symptoms (LUTS). We suspected that LUTS would differ between sympathetic hyperactive and hypoactive patients. Therefore, we measured HRV and divided the LUTS patients into two groups, a sympathetic hyperactive group and a sympathetic hypoactive group according to the low frequency/high frequency (LF/HF) ratio and made clinical comparisons between the groups. METHODS: A total of 43 patients with symptomatic LUTS (International Prostate Symptom Score [IPSS] over 8) and 49 healthy volunteers were enrolled. No subjects had diseases that could affect the autonomic nervous system, such as diabetes or hypertension. Electrocardiographic signals were obtained from subjects in the resting state and HRV indexes were calculated with spectral analyses. We divided the LUTS patients into two groups by an LF/HF ratio of 1.9, which was the median value in the healthy volunteers, and compared the differences in clinical characteristics, IPSS, prostate-specific antigen (PSA), and transrectal ultrasound (TRUS) results. The parameters were compared by independent sample t-test by use of SPSS ver. 19. RESULTS: There were no significant differences in age, serum PSA, or volume of the prostate between the 2 LUTS groups. However, analyzing IPSS questionnaires between two groups showed that there were significant differences in mean of Q2 score (frequency) and storage symptom score ([Q2+Q4+Q7]/3) (P<0.05). CONCLUSIONS: We suggest that an imbalance of autonomic nervous system activity may be a factor that evokes varieties of symptoms in men with LUTS. LUTS patients with hypoactive sympathetic tone may suffer from frequency and storage symptoms.

PURPOSE: The objective of this study is to investigate alteration of autonomic nervous system (ANS) activity in patients suffering from erectile dysfunction (ED) by comparing parameters of heart rate variability (HRV) between men with ED and healthy subjects. METHODS: A retrospective review was performed on 40 ED patients (mean age, 46.0+/-8.49 years) without any disease and 180 healthy control people (mean age, 44.4+/-7.83 years) without ED in our institution from June 2008 to July 2010. And electrocardiographic signals were obtained to measure HRV parameters for both patients and controls in a resting state. RESULTS: For the time domain analysis, square root of the mean differences between successive RR intervals (RMSSD) representing parasympathetic activity was lower in patients than controls although P-value was not statistically significant (P=0.060). For the frequency domain analysis, high frequency (HF) representing parasympathetic activity was lower in patients than controls (P=0.232) and low frequency (LF) representing mainly sympathetic activity was higher in patients than controls (P=0.416). Lastly, LF/HF ratio reflecting sympathetic/parasympathetic activity ratio was statistically higher in patients than controls (P=0.027). CONCLUSIONS: Patients with ED exhibited different HRV parameters compared with normal controls. This suggests that the patients with ED may have some kind of imbalance in the ANS and it may be possible that general imbalance of the ANS is one of the causes of ED. Thus, HRV analysis may give valuable diagnostic information and serve as a rapid screening tool to evaluate altered ANS activity in patients with ED.

PURPOSE: Stress urinary incontinence (SUI) and urge urinary incontinence (UUI) have different mechanisms of action. We believe that alteration of autonomic nervous system (ANS) activity may contribute to UUI because the lower urinary tract is regulated through the sympathetic and parasympathetic nervous systems. Heart rate variability (HRV) allows measurement of autonomic nervous function, therefore we measured and compared HRV parameters in women with urinary incontinence. METHODS: From March 2008 to March 2010, we evaluated all patients who visited 2 university hospitals for treatment of urinary incontinence. Theywere performed 3-day voiding diary, urodynamic study, physical examination and routine laboratory examination. We excluded subjects who had diabetes, cardiovascular problems, or other condition that affect ANS. Patients with mixed urinary incontinence (MUI) were also excluded. Finally 47 women with SUI (group 1) and 29 women with UUI (group 2) were enrolled according to their symptoms and voiding diary. We compared their HRV parameters. And excluding 11 patients who had detrusor underactivity, we divided them again into group A, 53 women without detrusor overactivity (DO) and group B, 12 women with DO. We compared HRV parameters between DO and non-DO group. RESULTS: Older women had a higher incidence of UUI and DO. In HRV parameters, only the ratio of low frequency (LF) and high frequency (HF) was significantly higher in group 2 than group 1 (3.5+/-3.6 vs. 1.6+/-1.1, P<0.05). Also group A had higher mean LF/HF ratio than group B (4.3+/-3.8 vs. 1.9+/-1.9, P<0.05). CONCLUSIONS: Increased LF/HF values indicate relative sympathetic hyperactivity over parasympathetic activity. Changes in ANS activity could indicate the presence of UUI and potentially DO.

PURPOSE: To identify autonomic dysfunction among patients with urinary incontinence (UI) with or without detrusor overactivity (DO), we measured and compared heart rate variability (HRV) in these groups. MATERIALS AND METHODS: We studied HRV in 12 female UI patients with DO (mean age, 57.3+/-11.0 years) and 53 female UI patients without DO (mean age, 56.8+/-9.8 years). HRV parameters were measured by SA-3000P(R). Heart rates, the time domain index, and the frequency domain index were compared. To compare time domain indexes, we used the standard deviation of the N-N interval (SDNN), the square root of the mean squared differences of successive N-N intervals (RMSSD), and the frequency domain indexes total power (TP), very low frequency (VLF), low frequency (LF), high frequency (HF), and the low-frequency/high-frequency ratio (LF/HF ratio). RESULTS: RMSSD values were lower in UI patients with DO than in those without DO, but the values of SDNN and HR showed no significant difference. Whereas the values of LF and HF were lower in UI patients with DO than in those without DO, the LF/HF ratio was higher. TP and VLF were not significantly different. CONCLUSIONS: RMSSD, HF, and LF were lower in DO patients than in controls without DO, but the LF/HF ratio was higher. This suggests that both sympathetic and parasympathetic activity is attenuated in DO, but the autonomic imbalance is higher.

PURPOSE: To investigate the incidence, clinical features, pathogenic bacteria, and risk factors associated with acute prostatitis after transrectal prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 923 transrectal ultrasound-guided needle biopsies of the prostate in 878 patients performed at our institution from June 2004 to May 2009. The indications for biopsy were generally serum prostate-specific antigen (PSA) elevation, abnormal findings on a digital rectal examination, or both. All biopsies were performed with the patient hospitalized except for 10 patients who refused to be hospitalized, and ciprofloxacin was administered as an antibiotic prophylaxis. The incidence, clinical features, pathogenic bacteria, and potential risk factors associated with acute prostatitis after prostate biopsy were evaluated. RESULTS: Acute prostatitis developed in 18 (2.0%) cases after prostate biopsy. Among them, 9 (1.0%) had bacteremia and 2 (0.2%) showed clinical features of sepsis. Of the total 50 urine or blood specimens sent for culture study, 27 (54.0%) specimens showed positive cultures, including E. coli in 25. Among the 27 culture-positive specimens, 26 (96.3%) were resistant to ciprofloxacin. Among the potential risk factors for acute prostatitis after prostate biopsy, biopsy performed as an outpatient procedure without a cleansing enema (p=0.001) and past history of cerebrovascular accident (p=0.048) were statistically significant. CONCLUSIONS: Fluoroquinolone is effective as an antibiotic prophylaxis for transrectal prostate biopsy in most cases. The incidence of acute prostatitis after transrectal prostate biopsy was 2.0%, and almost all cases were caused by fluoroquinolone-resistant E. coli. A cleansing enema is recommended before transrectal prostate biopsy.

The International Continence Society (ICS) defines urinary incontinence (UI) as the complaint of any involuntary leakage of urine. The common pathophysiology of UI in women involves an overactive detrusor or an incompetent urethral sphincter. Therefore UI is categorized as stress urinary incontinence (SUI), urge urinary incontinence (UUI), mixed urinary incontinence (MUI) and overflow incontinence. SUI and UUI are the two most common types of UI in women. According to Korean national survey in 2005, the prevalence of UI is 24.4% and the prevalence of UI increased with age. Of those women, 48.8% reported SUI, 7.7% UUI, 41.6% mixed UI. Therefore the proper diagnostic work-up is needed to increase clinical outcome because many treatment options are being in women with UI. Non-invasive treatments include behavioral therapy, pharmacotherapy. Especially anticholinergics are the cornerstone of UUI treatment, whereas surgical treatments, such as TOT, TVT, are considered as a gold standard of SUI treatment. The cure rate of TOT or TVT surgery for SUI revealed 80-90% according to many studies and complication rate is reported about 5%. Therefore, by effectively identifying and treating incontinence it is possible to significantly improve patients' quality of life.

PURPOSE: We investigated whether a short-term follow-up prostate-specific antigen (PSA) measurement before prostate biopsy is useful in predicting the presence of prostate cancer. MATERIALS AND METHODS: From January 2004 to May 2008, 670 patients underwent transrectal ultrasound-guided prostate biopsy. The initial PSA (PSA1) was measured at the first outpatient visit. The second PSA (PSA2) was measured the evening before prostate biopsy. Only the patients with a PSA1 between 2.5 and 20 ng/ml and an interval between PSA1 and PSA2 of between 7 and 90 days were included in this study. The short-term PSA velocity (PSAVm) was defined as {(PSA2-PSA1/interval (days)}x30. Prostate volume (PV), PSA1, PSA2, and PSAVm were compared between the patients with prostate cancer and those with benign histology. RESULTS: Of the 362 patients who fulfilled the entry criteria, 365 prostate biopsies were performed. The PSAVm differed significantly between patients with prostate cancer and those with benign histology (p=0.021). In patients with a PSA1 of 10-20 ng/ml, age, PV, PSA1, PSA2, and PSAVm were significantly different between patients with prostate cancer and those with benign histology, whereas in patients with a PSA1 of 2.5-10 ng/ml, only PV was significantly different. In multivariate logistic regression analysis excluding PSA1 and PSA2, PSAVm was a significant predictor of prostate cancer overall and in patients with a PSA1 of 10-20 ng/ml, but not in patients with a PSA1 of 2.5-10 ng/ml. CONCLUSIONS: PSAVm was significantly different between the benign group and the prostate cancer group. But, this difference was mainly the result of a falsely elevated PSA, and PSAVm was not a significant predictor of prostate cancer when the PSA1 was 2.5-10 ng/ml.

PURPOSE: Lower urinary tract symptoms (LUTS) are common, but their etiology and mechanism are still unclear. We believe that changes in autonomic nervous system (ANS) activity may be contributory, because the lower urinary tract is regulated through the sympathetic and parasympathetic nervous systems. Heart rate variability (HRV) is a tool by which autonomic nervous function can be measured, and therefore we measured and compared parameters of heart rate variability between men with LUTS and healthy subjects. MATERIALS AND METHODS: Thirty-nine men with LUTS [mean age 56.9+/-8.9 years old, International Prostate Symptom Score (IPSS)> or =8] and 23 healthy men (mean age 57.0+/-1.8 years old, IPSS<8) were included in the present study. HRV is known to be a useful tool for evaluating ANS activity, and we measured and compared HRV in the resting state. RESULTS: The standard deviation of the N-N interval (SDNN) and total power (TP) for patients with LUTS revealed no significant differences from those in the control group. On frequency domain analysis, there was evidence of decreased high frequency (HF) in patients with LUTS (p<0.05), but there were no significant differences in other parameters such as heart rate, square root of the mean squared differences of successive N-N intervals (RMSSD), very low frequency (VLF), low frequency (LF), or the LF/HF ratio. CONCLUSIONS: Patients with LUTS exhibited different HRV parameters compared with normal controls. Their decreased HF indicated that they may have had some kind of disease or imbalance in the autonomic nervous system, which may distinguish patients with LUTS from healthy men.

Spontaneous rupture of the renal pelvis or ureteropelvic juction area with extravasation of urine into the perinephric space is an uncommon pathologic condition (1). We report a case of 72-year-old woman who suffered 2 days of left loin pain. The patient has got residual urine sensation and weak urine stream since she has gone through a radical hysterectomy 17 years before. Because of these symptoms of voiding difficulty, the patient had abdominal straining during her urination. A CT scan exhibited renal pelvis rupture with perirenal extravasation of urine due to severe hydronephrosis, that was exacerbated by hidden neurogenic bladder disease. Moreover, the patient has detrusor underactivity and high intravesical pressure at voiding trial in the urodynamic study. One month after the percutaneous nephrostomy insertion into the left renal pelvis, the patient was successfully treated. The size of renal pelvis decreased. Moreover, urinoma disappeared in follow up CT scan image.

Voiding dysfunction is very common in Alzheimer's disease, especially urinary incontinence with reported frequencies of 11-90%. Urinary incontinence occurs secondarily from dementia, can result in medical morbidity, impaired self-esteem of the patents, caregiver's stress, early institutionalization of the patients, and considerable financial cost. Many studies have found that the frequency and severity of incontinence is positively correlated with the severity of dementia and the inability to walk or transfer. Research on the management of urinary incontinence in demented patients has focused almost exclusively on toileting programs and drug treatments for detrusor overactivity. To date, anticholinergic and antispasmodic medications have not been shown to be effective in treating incontinence in demented persons. Therefore we have to study about the etiology and treatment of Alzheimer's disease.

PURPOSE: To characterize autonomic dysfunction in patients with benign prostatic hyperplasia(BPH), we measured heart rate variability(HRV) and analyzed them compared with those of normal population. MATERIALS AND METHODS: ECG signals were obtained from 11 male patients(mean age, 63.1 years) and 23 healthy male controls(mean age, 57.0 years) in resting state. We analyzed their parameters of HRV and compared them between groups. RESULTS: Time domain analysis including standard deviation of NN interval(SDNN), square root of mean of sum of squares of differences between adjacent NN intervals(RMSSD) in patients with BPH were not significantly different with those of controls. There were suggested evidence of decreased total power(TP), high frequency (HF) in patients with BPH(p<0.05) while no significant difference in other frequency domain such as very low frequency(VLF), low frequency(LF) and LF/HF ratio. CONCLUSION: This preliminary study shows that patients with BPH have different results on HRV study comparing to controls. With the exception of LF and LF/HF ratio, all parameters of HRV in patients with BPH lower than normal controls. TP, HF in patients with BPH significantly lower than that of normal controls. The decreased values of HRV study means that they may have some kinds of disease or imbalance in autonomic nervous system(ANS). So we suggest that HRV study may be a tool to describe the possibility of altered ANS activity in patients with BPH.
