Purpose: This prospective study was designed to investigate the prevalence of urinary incontinence (UI), voided volume, post void residual volume (PVRV), daytime frequency and nocturia in women over 40 years. Methods: The sample comprised of 302 women over 40 years.The study lasted from February 2008 to November 2009. Data about daytime frequency and nocturia were gathered from 48 hour bladder diary. Further, a PVRV was assessed through a bladder ultrasonography. Data were analyzed using the t-test, Mann Whitney test, Kruskal Wallis test and multiple regression. Results: Although the prevalence of UI among the women was as high as 70.5%, the perception rate of UI was as low as 10.8%.Single voided volume of women without or with UI was 223 mL or 198 mL (p<.001), respectively; PVRV, 25.8 mL or 23.6 mL (p=.055); daytime frequency, 5.89 or 6.96 (p<.001); nocturia, 0.99 or 1.23 (p=.040). Age (${\beta}$=0.19, p=.001), single voided volume (${\beta}$=-0.16, p=.006), and nocturia (${\beta}$=0.12, p=.034) were associated with UI. Conclusion: The prevalence of UI was found to be 70.5% among the participants. The assessment of single urinary volume and nocturia through a bladder diary lends support to identifying UI for women over 40 years.

For the patients with bladder dysfunction, measurement of urine volume inside the bladder is very critical to avoid bladder failure. In measuring urine volume inside a bladder, low-resolution 3D ultrasound images are widely used. However, urine volume estimation from 3D ultrasound images is prone to big errors and inconsistency because of low spatial resolution and low signal-to-noise ratio of ultrasound images. We developed a new robust volume estimation algorithm which is not computationally expensive. We tested the algorithm on a lab-built ultrasound bladder phantom and volunteers. The average error rate of the human bladder volume estimation was 5.9% which was better than the commercial machine.

3D ultrasound bladder scanners are getting popular in hospitals for the patients with bladder dysfunction. A current bladder scanner adopts a mechanical scan to acquire 3D images and requires two motors and complicated mechanical devices. In this paper, we propose a new ultrasound bladder scanner using hand-motion scan. Instead of two motors and mechanical devices, it has a motion sensor to record transducer positions during hand-motion scan. The experiments with a bladder phantom and volunteers showed similar measurement accuracy to a conventional 3D ultrasound bladder scanner. We expect that the proposed method will reduce the cost and size of the bladder scanner.

Purpose: The purpose of this study was to identify the effects of a pre-operation video assisted education program on residual urine, gas passing and state anxiety in women undergoing hysterectomy. Methods: Nonequivalent control group non-synchronized design was used for the study. In the research, video assisted education program was applied to the experimental group while a similar conventional education was done to the control group. The pre-operation state anxiety and post-operation residual urine and gas discharge of both the groups were measured. The data were analyzed using SPSS. Results: The experimental group was significantly higher than control group on gas passing (t=3.04, p=.00). However the residual urine (t=0.34, p=.73) and state anxiety (t=0.81, p=.82) did not make significant differences. Conclusion: This study is very meaningful in that it developed and provided a nursing intervention can positively affect hysterectomy patients. The pre-operation video assisted education program may be an effective nursing intervention that is clinically practical and useful to reduce time of the gas passing of hysterectomy patients after the operation.

Purpose: The aims of this study were to develop and apply the urinary elimination facilitation program for stroke patients with urinary disorders and evaluate the effectiveness of the program. Methods: This study was conducted using the non-equivalent control group pre- posttest design. The participants included 23 patients in the control group and 22 in the experimental group. Data were collected from Nov. 25, 2013 to Nov. 25, 2014 in acute rehabilitation inpatient wards. For the final analysis, 35 patients' data were utilized 17 in the control group and 18 in the experimental group. The developed urinary elimination facilitation program was continued for 7 days and the program consisted of logging urination, monitoring timely voiding, assisting urinary elimination, and stimulating urination using sound. The data were analyized using the SPSS-win (version 21). Results: The number of urinary catheterization and the urinary discomfort were significantly improved in the experimental group compared to the control group. However residual urine and the occurrence of urinary tract infections were not significantly different between the experimental and control groups. Conclusion: The results of this study indicated that the urinary elimination intervention program for stroke patients with urination disorder could be useful in decreasing the number of urinary catheterization and the urinary discomfort.

대부분의 정상 소아는 하루에 수7회 정도씩 배뇨를 한다. 일부 소아에서는 하루에 2회 이하로 배뇨를 하는데, 이 경우를 infrequent voiding이라 지칭한다. 이들의 경우 대개 장기간 수의적으로 소변을 참아오는 경우가 대부분이다. 이러한 비정상적인 배뇨습관으로 인하여 종종 방광 용적이 증가되며, 잔뇨량이 늘어나고 배뇨의 욕구가 감소됨으로써 만성적인 방광확장과 함께 재발성 요로감염 및 신손상까지 초래될 수 있다. 본 보고자들은 13세의 여아에서 하루 2차례 이하로 매우 드물게 배뇨를 하는(가뭄뇨) 습관으로 인하여 요로감염과 신손상이 초래된 증례를 경험하였기에 문헌고찰과 함께 보고하고자 한다.

This study is to increase the accuracy of the diagnosis of benign prostatic hyperplasia by presenting a method that can accurately measure the residual urine amount of the bladder by using an ultrasound image. Agar powder, Propanol and distilled water were used as materials for making a phantom. In order to measure the volume, a $10m{\ell}$ cylinder, syringe and beaker were used. The image was obtained by scanning phantoms produced into six shapes. Each constant value was obtained by using the expression designed to measure the residual urine amount of the bladder and was compared and analyzed. The measuring method of Bladder volume was presented and a constant value for each shape was obtained and five observers measured it five times. According to the results of clinical application, the errors of Ellipse-beanbag, Shield-shield were 11.0%, 18.2%, respectively. Constant values depending on the shape of each phantom were presented in order to accurately measure the volume of the bladder in measuring the amount of residual urine for the diagnosis of benign prostatic hyperplasia. The accuracy of the volume using this was verified statistically(p > 0.05). Therefore, it is considered to be useful in diagnosing benign prostatic hyperplasia by using the ultrasound imaging measuring method presented.
