Purpose: The objective of this study was to examine the psychological features and coping strategies of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Materials and Methods: The participants consisted of 55 military personnel suffering from CP/CPPS and 58 military personnel without CP/CPPS symptoms working at the Military Capital Hospital. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was used to assess CP/CPPS symptoms. The Responses to Hospital Anxiety and Depression (HAD) scale, Social Readjustment Rating Scale, and Global Assessment of Recent Stress (GARS) scale were compared between the two groups. The Weisman Coping Strategy Scale was used to assess coping ability with CP/CPPS. Results: The NIH-CPSI score of the CP/CPPS group was significantly higher than that of the control group for all domains including pain, urinary symptoms, quality of life, and summed score. The Anxiety and Depression domain of the HAD showed significant differences between the two groups. There were no significant differences in the Social Readjustment Rating Scale between the two groups, but the sum of the GARS score was higher in the CP/CPPS group than in the control group. These were correlated with the pain, quality of life, and sum domains of the NIH-CPSI. The Weisman Coping Strategy Scale showed that intellectualization, redefinition, and flexibility were higher in frequency in descending order, and that fatalism, externalization, and self-pity were lower in frequency. Conclusions: The CP/CPPS patients had depression, anxiety, and higher perception of stress. In particular, these were closely related to the pain and quality of life of the patients Purpose: The objective of this study was to examine the psychological features and coping strategies of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

The characteristics of combustion and pollutant emission from a fluidized bed incinerator, in which waste activated sludge from municipal sewage treatment plant was burnt on the staged combustion modes, were investigated under the several operating conditions. The dried waste activated sludge with the moisture content of 4.5% and the heating value of about 4,200 kacal/kg dry solid was used in this study. With the variation of operating paramenters, such as bed temperature, superficial air velocity, and excess air ratio, temperature distributions in the incinerator and characteristics of ash drain rates and pollutant emission from the incinerator were measured. As the dried sludge had high volatile content, the maximum temperature appeared at upper region of fluidized bed surface in measured temperature distributions and the axial position of maximum temperature moved up with increase of superficial air velocity. The measured combustible contents of fly ash and bottom ash were lower than 3% and 0.4%, respectively. Thus, combustion efficiencies showed very high values of over 99.6% and were not severly affected by the variations of bed temperature and superficial air velocity. However, as the excess air ratio was increased, combustion efficiencies were decreased by the temperature drop in the freeboard region. The concentration of Co in exhausted gas was increased substantially with the increase of superficial air velocity which could reduce residence time of devolatilized gas in the freeboard. However, concentrations of SO₂and No?? were decreased slightly with the increase of superficial air velocity.

Purpose: To assess the risk factors for developing urinary retention after removal of the urethral catheter on postoperative day 1 in benign prostatic hyperplasia patients who underwent Greenlight HPS laser photoselective vaporization prostatectomy (PVP). Materials and Methods: The study included 427 men who underwent Greenlight HPS laser PVP between 2009 and 2012, excluding patients in whom a catheter was maintained for more than 1 day because of urethral procedures. In all patients, a voiding trial was performed on postoperative day 1; if patients were unable to urinate, the urethral catheter was replaced before hospital discharge. The patients were divided into two groups: early catheter removal (postoperative day 1) and late catheter removal (urethral catheter reinsertion). Preoperative and perioperative parameters were compared between the groups. Results: Catheters were successfully removed in 378 (88.6%) patients on postoperative day 1. In 49 patients, the catheters were reinserted and removed a mean of 6.45±0.39 days after surgery. In a multivariate analysis, a history of diabetes was the most significant predictor (p=0.028) of failure of early catheter removal, followed by operative time (p=0.039). There were no significant differences in age, prostate volume, International Prostate Symptom Score, or urodynamic parameters between the two groups. Conclusions: It is feasible, safe, and cost-effective to remove the urethral catheter on postoperative day 1 after Greenlight HPS laser PVP, but the procedure should be done carefully in patients who have history of diabetes or an extended operative time.

Purpose: This study analyzed the type of acute urinary retention (AUR) and evaluated the treatments used, including trial without catheter (TWOC). Materials and Methods: This study was based on 299 patients who were treated for AUR from January 2007 to August 2009. The patients were classified into the spontaneous AUR group (group S) and the precipitated AUR group (group P), in which AUR was consecutive to triggering events. The treatment modalities including TWOC, the success rate of TWOC, age, prostate-specific antigen (PSA) levels, the volume of the prostate, and the drained volume at catheterization were analyzed in each group. Results: Of 299 men with AUR, 160 (54%) had spontaneous AUR and 139 (46%) had precipitated AUR. Compared with group P, patients in group S were more likely to be treated by surgery, either immediately (16.9% vs. 3.6%, p<0.05) or after prolonged catheterization (42.2% vs. 29.1%, p<0.05). The success rate of TWOC was lower in men of older ages (≥70 years) and in those with enlarged prostates (≥50 ml), higher PSA levels (≥3 ng/ml), and a large drained volume at catheterization (≥1,000 ml). Conclusions: In this group of AUR patients, there were slightly more patients with spontaneous AUR (54%) than with precipitated AUR (46%). The success rate of TWOC was more than 70% regardless of the type of AUR. Although TWOC is recommended primarily in the treatment of AUR, early surgical intervention should be considered if the patient has an enlarged prostate (≥50 ml) or a large drained volume at catheterization (≥1,000 ml).
