Prognostic accuracy of the quick sequential organ failure assessment (qSOFA) score for mortality may be limited in elderly patients. Using our multi-institutional database, we classified obstructive acute pyelonephritis (OAPN) patients into young and elderly groups, and evaluated predictive performance of the qSOFA score for in-hospital mortality. qSOFA score ≥ 2 was an independent predictor for in-hospital mortality, as was higher age, and Charlson comorbidity index (CCI) ≥ 2.

Objectives: To investigate the oncological and functional outcome of distal ureterectomy compared with nephroureterectomy in the management of distal ureteral urothelial carcinoma.

Methods: Using a database including upper urinary tract urothelial carcinoma patients (n = 1329), 282 patients were identified with urothelial carcinoma localized in the distal ureter on clinical evaluation. To adjust for potential baseline differences between groups, 43 patients undergoing distal ureterectomy were matched with 86 patients undergoing nephroureterectomy using propensity scoring.

Objectives: We conducted a preliminary study to examine the validity of assessment criteria of lower urinary tract symptoms (LUTS) severity for general practitioners (GPs).

Materials And Methods: This study included 194 patients with LUTS, who visited the urology clinics in three hospitals. In 177 who completed International Prostate Symptom Score (I-PSS), International Consultation on Incontinence Questionnaire : Short-Form (ICIQ-SF), frequency-volume chart, uroflowmetry and post-void residual urine measurement, three overall grades (mild, moderate and severe) of LUTS were determined using the newly-developed assessment criteria for GPs.

As the population ages rapidly, we need to establish a cost-effective system to assess and treat urination problems of the elderly. Recently, criteria have been developed for urologists to assess benign prostatic hyperplasia using the International Prostate Symptom Score (I-PSS), QoL index, urination function (maximal flow rates and residual urine volume) and prostate volume. It is suggested that patients with moderate to severe urination problems as measured by these criteria need to be treated but those with mild problems have no need for treatment.

Criteria for general practitioners to assess treatment efficacy are needed to efficiently treat urination problems in the elderly. Recently, criteria have been developed for urologists to assess the efficacy of benign prostatic hyperplasia treatment using the International Prostate Symptom Score (I-PSS), QoL index and maximal flow rates. We examined whether these criteria can be applied to the general urination problems of the elderly men and women, with 85 male and 16 female subjects aged 50 and over.

Objectives: Lower urinary tract symptoms (LUTS) are reported to influence the quality of life (QoL) of the elderly. The aim of this study was to elucidate the relationships among filling problems, voiding problems and QoL in elderly men and women.

Methods: A total of 450 males and 228 females, aged 50 years or older responded to a questionnaire, which included seven questions from the International Prostate Symptom Score (I-PSS) and 16 questions from the King's Health Questionnaire (KHQ).

Objectives: To investigate the relationships among lower urinary tract symptoms (LUTS), satisfaction at urination, and quality of life (QoL) in elderly Japanese men and women, who attended physicians for their medical problems.

Methods: A total of 437 Japanese men and 196 women, aged 50 or older, responded to a questionnaire, which included seven questions regarding urination, one question about bothersomeness (QoL index) from the International Prostate Symptom Score (IPSS), two questions about frequency of urinary incontinence and 16 questions from the King's Health Questionnaire (KHQ).

Results: Of 401 patients who completed the IPSS and KHQ questionnaires, 235 (72.
