Prognostic Accuracy of the qSOFA Score for In-Hospital Mortality in Elderly Patients with Obstructive Acute Pyelonephritis: A Multi-Institutional Study.

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. In young patients, the area under the curve (AUC) of the qSOFA score for in-hospital mortality was 0.85, whereas it was 0.61 in elderly patients. The sensitivity and specificity of qSOFA score ≥ 2 for in-hospital mortality was 80% and 80% in young patients, and 50% and 68% in elderly patients, respectively. For elderly patients, we developed the CCI-incorporated qSOFA score, which showed higher prognostic accuracy compared with the qSOFA score (AUC, 0.66 vs. 0.61, p < 0.001). Therefore, the prognostic accuracy of the qSOFA score for in-hospital mortality was high in young OAPN patients, but modest in elderly patients. Although it can work as a screening tool to determine therapeutic management in young patients, for elderly patients, the presence of comorbidities should be considered at the initial assessment.

Equivalent survival and improved preservation of renal function after distal ureterectomy compared with nephroureterectomy in patients with urothelial carcinoma of the distal ureter: a propensity score-matched multicenter study.

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. Cox regression models tested the effect of surgery type on recurrence-free survival and cancer-specific survival. Estimated glomerular filtration rate was measured before and after surgery. RESULTS: The median follow-up period was 50 months. There were no significant differences in 5-year recurrence-free survival and cancer-specific survival rates between the distal ureterectomy and nephroureterectomy groups (P = 0.22 and P = 0.70, respectively). Multivariate analysis showed that surgery type was not associated with recurrence-free survival and cancer-specific survival (P = 0.90 and P = 0.28, respectively). In the subanalysis, recurrence-free survival and cancer-specific survival in the distal ureterectomy group were equivalent to those of the nephroureterectomy group in both pTa-1 and pT2-4 patients. Renal function was better preserved in the distal ureterectomy group than in the nephroureterectomy group (rate of change in estimated glomerular filtration rate 2% vs -20%; P < 0.001). CONCLUSIONS: The oncological outcome of distal ureterectomy is comparable with that of nephroureterectomy in distal ureteral urothelial carcinoma patients, and distal ureterectomy provides better preservation of renal function. Distal ureterectomy would be feasible for carefully selected patients with distal ureteral urothelial carcinoma.

[A case of papillary cystadenoma of the epididymis mimicking a testicular tumor].

A 68-year-old male presented with painless left scrotal enlargement of one year duration. Ultrasound, computed tomography (CT) and magnetic resonance imaging showed a multilocular cystic mass, 10×7.5× 8.5 cm in size, in the left scrotum. The intracystic fluid was partially hemorrhagic. A solid part of the tumor, seen at the base of the scrotum, was partially calcified and was enhanced by contrast medium. The left testis could not be identified by imaging studies. Although CT imaging showed a simple cyst in the right kidney, no other lesions in the kidneys, adrenal glands, pancreas or the central nervous system were detected. Serum tumor marker values for testicular cancer were within the normal range. Under the pre-operative diagnosis of a left testicular tumor, left high orchiectomy was performed. Grossly the specimen consisted of a multilocular cystic tumor, 12.5×8.5×8.5 cm in size, with a 2.7 cm tan-colored solid component within the wall of the cyst. The left testis was atrophic, 1.3 cm in size, and demonstated no continuity with the solid part of the tumor. Histologically, the solid component of the tumor showed tubular and papillary growth of cuboidal and columnar tumor cells with clear cytoplasm. Histopathological diagnosis of papillary cystadenoma of the epididymis (PCE) was made. Von Hippel-Lidau disease was ruled out by subsequent genetic analysis. After follow up for 18 months, there was no sign of recurrence. To our knowledge, this is the 33rd and the largest case of PCE reported in Japan.

[Assessment criteria of lower urinary tract symptom severity for general practitioners].

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. The relationship between diagnoses and treatments by the urologists, and overall LUTS grades were examined. RESULTS: All of the 70 patients with "severe" grade and 68 (94%) of 72 with "moderate" grade were diagnosed as having urination problems. Sixty-eight (97%) with "severe" grade and 64 (89%) with "moderate" grade were treated with fluid restriction, behavioral therapy, and/or drug therapy. Of 35 with "mild" grade, 17 (49%) were diagnosed as having normal urination. In this grade, eight patients (23%) were treated with fluid restriction and 15 (43%) with drug therapy. CONCLUSIONS: 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.

[Criteria for general practitioners to assess treatment efficacy for urination problems of the elderly].

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. Furthermore, we set Level I criteria using the I-PSS and QoL indices. Level II criteria using I-PSS, QoL index and post-void residual urine in addition to Level III criteria using I-PSS, QoL index and maximal urine flow rate. Correspondence rates among assessments by these criteria of treatment efficacy were investigated. Ninety-nine of 101 patients (98.0%) were assessed properly using the Level III criteria but the efficacy graded as "fair" and "unchanged" in Level III in each patient should be "poor" and "fair" in reality. Our findings suggest that Level III criteria should be useful for assessing the treatment efficacy of urination problems of elderly men and women besides benign prostatic hyperplasia. All of the patients, whose treatment efficacy was graded as "excellent" or "good", and those with efficacy graded as "unchanged" or "poor", according to the Level I criteria, were appropriately assessed by the Level III criteria. Of 35 patients whose treatment efficacy was graded as "fair" at Level I, the efficacy of 6 patients was graded as "unchanged" according to Level III. All of the patients, whose treatment efficacy was graded as "excellent" or "good", and those with efficacy graded as "poor", according to the Level II, were also appropriately assessed by the Level III criteria. However, the efficacy of 11 and 4 patients of 38 and 35 patients, respectively, whose efficacy was graded as "fair" and "unchanged" at Level II, was graded as "unchanged" and "fair" according to Level III, respectively. We believe that simple criteria including only I-PSS and QoL index are useful for general practitioners to assess treatment efficacy of urination problems in the elderly. It is suggested that patients with efficacy graded as "unchanged", or "poor" should be referred to a urologist but those with efficacy graded as "excellent", "good" and "fair" should be treated continuously. However, 17% of the patients with efficacy graded as "fair" by Level I criteria might be judged "unchanged" from the viewpoint of urologists.

[Initial assessment criteria for urination problems of the elderly--comparison of criteria for patients/caregivers/nurses, general practitioners, and urologists].

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. We examined whether these criteria can be applied to the general urination problems of elderly men and women, with 112 men and 21 women aged 50 and over as subjects. Furthermore, we set Level I criteria for the elderly themselves, their families or nurses taking care of them, using I-PSS and QoL index, and Level II criteria for general practitioners, using I-PSS, QoL index and residual urine volume, in addition to Level III criteria for urologists (omitting prostate volume in women). Correspondence rates among severities of urination problems at Level I, II and III, and sensitivities and specificities of Level I and II criteria were investigated. One hundred twenty-one patients of 124 with moderate to severe urination problems at Level III needed to be treated and eight of nine with mild urination problems did not. As a whole, our findings suggested that 129 of 133 patients (97.0%) were correctly assessed at Level III. We found that Level III criteria were valid for general urination problems of the elderly, not just benign prostatic hyperplasia. While 102 and 111 patients were judged as having moderate or severe urination problems, respectively, at Level I and Level II, and all of these were diagnosed as having moderate or severe problems at Level III, 22 (71.0%) of 31 and 13 (59.1%) of 22 patients judged as having mild urination problems at Level I and Level II were diagnosed as having moderate problems at Level III. Although specificities of Level I and Level II criteria were 100%, sensitivities improved from 82.3% (102/124) to 89.5% (111/124), adding residual urine measurement to the I-PSS and QoL scores. Polyuria of more than 2,000 ml per day was noted in 33 patients (24.8%). At Level I, residual urine of 50 ml or more was noted in 9 (29.0%) patients with mild urination problems, in 22 (24.2%) with moderate problems and in 4 (36.4%) with severe problems. Assessment criteria for general practitioners should include a frequency-volume chart and measurement of residual urine. When the elderly are judged as having moderate or severe urination problems according to either Level I or II criteria, they need treatment. However, more than half of the elderly, judged as having mild problems according to those criteria, need treatment from the standpoint of urologists.

The relationships among filling, voiding subscores from International Prostate Symptom Score and quality of life in Japanese elderly men and women.

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). The relations among the filling, voiding subscores deliverable from I-PSS, and KHQ-QoL were investigated. RESULTS: The voiding subscore significantly correlated with the filling subscore with a considerably large standard deviation, and the filling subscore also significantly correlated with I-PSS in both genders. KHQ-QoL was significantly associated with the filling and voiding subscores in almost all domains of the KHQ. Multiple regression analyses demonstrated the filling, voiding subscores, and I-PSS explained the 55% or greater reduction in the QoL in six, four, six domains in men and four, three, four domains in women, respectively. CONCLUSIONS: The filling problems are slightly more associated with KHQ-QoL than voiding problems but filling problems did not appear to predominantly affect QoL as expected in both genders. We believe it valid to use I-PSS to evaluate voiding problems as well as filling problems in the elderly women.

"Quality of life" assessment of urination in elderly Japanese men and women with some medical problems using International Prostate Symptom Score and King's Health Questionnaire.

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 (72.3%) men and 85 (64.7%) women had moderate to severe LUTS. In both genders, LUTS severity was significantly correlated with satisfaction status and KHQ-QoL domain scores. Satisfaction status also correlated with KHQ-QoL scores. Thirty-eight (13.5%) men and 27 (22.7%) women had frequent incontinence episodes. When excluding the patients with frequent incontinence episodes, KHQ-QoL scores of severe LUTS decreased in the domains of role, physical and social limitations, personal relationships and sleep/energy in women alone. CONCLUSIONS: Urination problems and related QoL status could be easily assessed by IPSS and QoL index in the elderly. Urinary incontinence appeared to be more associated with QoL in elderly women. The KHQ may be useful to assess the detailed urination-related QoL status of elderly men and women with LUTS or urinary incontinence.

[Functional and urodynamic characteristics in patients with ileal neobladder].

We analyzed the functional and urodynamic characteristics in 19 patients with ileal neobladder by the Hautmann procedure. A questionnaire survey by mail was performed for functional information of neobladder. Seventeen of the 19 patients (89.5%) could voluntarily void via the urethra and the others needed clean intermittent self catheterization (CIC) because of their significant residual volume. Eight of the 19 patients (42.1%) micturated at least two times at night. Two of the 19 patients (10.5%) were incontinent in the day time and 12 (63.2%) in the night time. They needed 2 pads in the day time and one pad at night on average. Eight out of 18 patients (44.4%) were satisfied with their micturition state. A urodynamic study showed the neobladder to be a low-pressure reservoir with a mean capacity of 395.2 +/- 96.8 ml. The mean residual volume of the patients without CIC was 27.8 +/- 28.2 ml. In 10 out of 11 patients high frequency and high amplitude spikes were seen by the perineal electromyogram in the voiding phase.
