The anti-reflux ureteral stent was successfully designed and fabricated using a 3D printer. In vitro studies showed that the stent effectively prevented backward flow while minimizing reduction in forward flow.

AIMS: Fibromyalgia syndrome (FMS) is the most common disease causing chronic generalized pain, and FMS patients often complain of urinary symptoms such as frequency or urgency. This study focuses on the association of overactive bladder (OAB) and FMS in adults aged 40 and over. METHODS: A survey of adults aged 40s and over was conducted in the Guri and Yangpyeong areas of South Korea. The response rate was 74.2% (940/1,266). After excluding subjects with incomplete questionnaires (n = 20), 920 w

AIM: To evaluate the association between lower urinary tract symptoms (LUTS) and incidental falls and fear of falling. METHODS: We used data obtained from the 2011 Korean Community Health Survey (KCHS) conducted between August and October 2011 in South Korea. The survey was carried out to estimate patterns of disease prevalence and morbidity in men >40 years old. The trained interviewers performed face-to-face sociodemographic questionnaires using computer-assisted personal interviewing (CAPI) s

Indwelling urinary catheters (IUCs) are used in clinical settings to assist detrusor contraction in hospitalized patients. However, an inserted IUC often causes catheter-related bladder discomfort. To resolve this, we propose an IUC coupled with local, sustained release of an anesthetic drug, lidocaine. For this, a thin strand composed of poly (lactic-co-glycolic acid) and lidocaine was separately prepared as a drug delivery carrier, which was then wound around the surface of the IUC to produce

The author presents the performance of convolutional codes truncated by input information of finite length. In a convolutional code, the error rates of each bit are different. The upper bound on the error rate for each bit within a convolutional code is derived and analysed.

OBJECTIVE: This study was conducted to examine the effect of discontinuing tamsulosin in patients with benign prostatic hyperplasia who had been receiving combination therapy with tamsulosin and dutasteride. METHODS: The study sample consisted of 108 men with benign prostatic hyperplasia and lower urinary tract symptoms who visited our urology clinics between April 2008 and December 2010. All were assessed using the International Prostate Symptom Score (IPSS). The patients had IPSS of 8-19 and p

Erectile dysfunction (ED) and depression are closely related. We sought to determine ED and depression were improved by tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, at 5 mg daily, in this case-control study.Participants were men aged 20 to 65 years with ED for >3 months, International Index of Erectile Function-5 (IIEF) score <21 points, and Zung Self-Rating Depression Scale (SDS) survey result >50 points who were willing to participate.On first visit (V1) and after 1 (V2) and 2 month
