OBJECTIVE To investigate the reliability and validity of the King’s Health Questionnaire (KHQ) in both genders, which was originally developed as a health‐related quality of life (HRQoL) questionnaire for female urinary incontinence for general lower urinary tract symptoms (LUTS). SUBJECTS AND METHODS Data from the International Prostate Symptom Score (IPSS) and KHQ obtained from 179 men and 75 women consulting urologists (Sample A) were analysed. Cronbach’s α coefficient and inter‐domain correlation were calculated for reliability and validity assessment, respectively. Factor analysis was used to explore the underlying factor structure of the KHQ. KHQ scores of sample A were compared with those of 330 men and 418 women consulting general practitioners (Sample B). RESULTS Internal consistency of KHQ was acceptable with a Crohnbach’s α of 0.721–0.915 in the total population of sample A. Correlation analysis showed convergent validity among ‘Physical Limitations’, ‘Role Limitation’ and ‘Social Limitations’ and discriminant validity among ‘Personal Relationship’, ‘Emotion’s and ‘Sleep/Energy’. Factor analysis showed three underlying components to explain convergent and discriminant validity. In both sample A and sample B, HRQoL was impaired in the eight domains according to IPSS severity. KHQ scores of domains other than ‘General Health Perception’ in sample B were lower than those in sample A. CONCLUSION The KHQ can be used as a HRQoL questionnaire for LUTS in both genders. In the future, it is expected that the KHQ could be used in clinical studies for benign prostate hyperplasia and other conditions.
This preliminary study revealed that our criteria of LUTS severity for GPs were useful to determine whether the elderly patients should be treated or not. It is necessary to examine the validity of the criteria in a model in which GPs participate.
Objectives: Various types of minimally invasive surgical treatments, including transurethral resection of prostate (TURP), are being carried out in Japan for patients with benign prostatic hyperplasia (BPH). The aim of the present study was to elucidate the current status of perioperative care for these treatments by carrying out a nationwide survey. Methods: Assisted by the Japanese Endourology and ESWL Association, perioperative data from 157 institutions participating in this survey were collected and analyzed. Results: This survey included 3918 patients undergoing TURP, 242 TUR in saline (TURis), 638 holmium laser enucleation of the prostate (HoLEP), 90 holmium laser ablation (HoLAP) and 241 photoselective vaporization (PVP). Mean operative time was shorter in TURP (71 min) and longer in HoLEP (127). Although no transfusions were required in cases undergoing HoLAP or PVP, blood was frequently transfused in those undergoing TURis (25.6%), TURP (10.2%) and HoLEP (7.8%), and the difference was significant. During the hospital stay, the incidence of TUR-syndrome, postoperative bleeding requiring bladder irrigation, acute urinary retention/difficulty on micturition and pad use at discharge was highest in TURP (2.3%), TURis (7.9%), HoLAP (16.7%) and HoLEP (15.1%), respectively. Two patients undergoing TURP died (0.05%). The shortest mean postoperative hospital stay was for PVP (1.6 days, even if the readmission rate within 90 days was the highest in this same group; 6.2%). Perioperative care during hospital stay varied among the five types of procedures. Conclusions: This survey provides useful documentation on the current status of minimally invasive treatments for BPH in Japan. Complication rates for TURP are not significantly higher as compared with other procedures. Thus, TURP can still be considered as the gold standard for BPH treatment.
Abstract:The objective of the present study was to assess the short-term effects of botulinum toxin A (BTX-A) injection for refractory non-neurogenic overactive bladder (OAB) in the setting of a prospective multicenter clinical trial. Refractory OAB was defined as persistent urgency urinary incontinence (UUI) Նonce a week despite taking anticholinergic agents, or the incapability to continue the agents because of the adverse effects. A total of 100 U of BTX-A were reconstituted in 15 mL of normal saline and an aliquot of 0.5 mL was injected at 30 submucosal sites of the bladder wall. Nine men and eight women aged 67 Ϯ 12 years were included. Subjective daytime frequency, urgency and UUI significantly decreased after treatment. On a 3-day frequency-volume chart, the daytime and night-time frequency of UUI significantly decreased from 5.5 and 0.5 pre-injection to 2.0 and 0.3 postinjection, respectively. Daytime urinary incontinence completely disappeared in six subjects. A urodynamic study showed the disappearance of detrusor overactivity in eight patients and a decrease in five patients. Maximum bladder capacity significantly increased from 179.9 to 267.3 mL. Difficulty on micturition or feeling of incomplete emptying was reported by 23.5% and 43.8% of patients at weeks 2 and 4, respectively. Postvoid residual urine increased to >100 mL in seven patients and >200 mL in one patient after injection; however, none of the patients required clean intermittent catheterization. These findings suggest promising efficacy of BTX-A in Japanese OAB patients.
