Overactive bladder symptoms in patients undergoing rigid and flexible cystoscopy.

PURPOSE: To evaluate overactive bladder (OAB) symptoms in patients undergoing diagnostic cystoscopy. Overall changes in the entire study population were assessed, as well as broken down by various subgroups. METHODS: A prospective multi-center study among consecutive 450 adults undergoing diagnostic cystoscopy was conducted. OAB-symptoms were evaluated with the validated eight-item OAB Screening Awareness Tool (OAB-V8) immediately before and on days 1, 4, and 7 after cystoscopy. Patients were distinguished between being OAB-negative and OAB-positive (< 8 and ≥ 8 sum-score, respectively). Average sum-scores and subdomains were evaluated. RESULTS: Before cystoscopy, 44.7% of patients were screened OAB-positive and 55.3% OAB-negative. Out of those being screened negative, development of de-novo OAB was noticed in 16.8%, declining to 8.1% on day 7 (p < 0.001). In patients being OAB-positive before cystoscopy, a decline of OAB-positivity was noted during follow-up (p < 0.001). No statistically significant differences were noted when broken down by gender (p = 0.92), age (p = 0.82) and type cystoscope (rigid vs. flexible, p = 0.38). Average sum-scores declined from 8.68 before cystoscopy to 6.9 during follow-up. Flexible cystoscopy was superior over rigid in four subdomains: uncomfortable urge to urinate (p = 0.04), sudden urge to urinate with little or no warning (p = 0.02), uncontrollable urge to urinate (p = 0.03), and urine loss associated with a strong desire to void (p = 0.009). CONCLUSION: OAB-symptoms are common in patients undergoing cystoscopy. Cystoscopy itself can cause de-novo OAB-symptoms. Controversially, a decline of OAB-symptoms was noted after cystoscopy when patients were screened OAB-positive before cystoscopy. Flexible scopes were superior in some subdomains.

Anxiety and depression analyses of patients undergoing diagnostic cystoscopy.

PURPOSE: To prospectively assess anxiety and depression in patients undergoing diagnostic cystoscopy. METHODS: Patients presenting for outpatient diagnostic cystoscopy were recruited from four European urological departments. Anxiety and depression were assessed with the 'Hospital Anxiety and Depression Scale' (HADS) before cystoscopy and after 1 week. Statistical analyses, including the Chi-square test, univariate, and multivariate logistic regression analyses, were carried out with SPSS v. 21 (IBM Corp., Armonk, NY). RESULTS: Prior to cystoscopy, 30.2 % of patients were anxious and 24.8 % depressive (n = 442). In the post-examination period, anxiety declined to 24.5 %, while depression was unchanged (24.4 %). Pre-cystoscopy anxiety was significantly more common in women (41.8 vs. 24.5 %, p < 0.0001), patients aged <65 years (34.9 vs. 25.9 %, p = 0.04), and in those being examined with rigid cystoscopes (35.7 vs. 23.9 %, p = 0.007). In multivariate regression analyses, female gender (OR 2.6, p < 0.0001), <65 years of age (OR 1.7, p = 0.03), and coexistence of depression (OR 7.8, p < 0.0001) were independently associated with elevated pre-cystoscopy anxiety. Anxious (OR 2.1, p = 0.03) and depressive (OR 2.1, p = 0.01) patients had higher odds of experiencing moderate or severe pain during cystoscopy. Bladder cancer diagnosis did not significantly change patient's anxiety (p = 0.23) or depression (p = 0.7) during the 1 week of follow-up. CONCLUSIONS: Women, patients aged <65 years, depressive patients and those being examined with rigid devices had higher rates of anxiety prior to cystoscopy. Anxious and depressive patients experienced more pain during cystoscopy. Bladder cancer diagnosis seems to have a minor effect on anxiety and depression during the first week after diagnosis.

Prospective, multi-institutional pain assessment of 150 women undergoing diagnostic cystoscopy.

BACKGROUND: The aim of this study was to prospectively assess women's pain during rigid and flexible diagnostic cystoscopy and afterwards during a one-week follow-up. METHODS: Prospective, multi-institutional trial analyzing numeric rating scales (NRS) of women undergoing diagnostic cystoscopy. Pain categories: no (0 points), mild (1-3), moderate (4-6) and severe pain (7-10). Assessing of pain before, during cystoscopy, and at day 1, 4 and 7 of follow-up. RESULTS: A total of 150 women undergoing rigid (N.=85) or flexible (N.=65) diagnostic cystoscopy were analyzed. Women undergoing flexible cystoscopy were more frequently pain-free (64.6% vs. 40%, P=0.003) and experienced mild pain less frequently (27.7% vs. 52.9% vs. P=0.002). No significant differences were noted among moderate (6.2% vs. 5.9%, P=0.95) and severe pain (1.5% vs. 1.2%, P=0.85). Patients undergoing their first (P=0.14) and repeat cystoscopy (P=0.08) had similar pain perception. In multivariate logistic regression analyses, women undergoing flexible cystoscopy had a 2.6 increased chance of being pain-free (OR=2.6, CI: 1.28-5.11, P=0.08) and their odds of experiencing mild pain were significantly lower (OR=0.34, CI: 0.17-0.71, P=0.004). The likelihood of experiencing moderate (OR=1.1, CI: 0.28- 4.4, P=0.83) or severe pain (OR=2.42, CI: 0.11-51.79, P=0.57) differed insignificantly. CONCLUSIONS: Rigid and flexible cystoscopies were well-tolerated by most women. However, flexible cystoscopy was associated with a higher likelihood of being pain-free and lower chances of experiencing mild pain. Patients' previous experience with cystoscopy did not influence pain perception.

Prospective multi-institutional study analyzing pain perception of flexible and rigid cystoscopy in men.

OBJECTIVE: To evaluate pain perception in men undergoing flexible or rigid diagnostic cystoscopy. METHODS: This is a prospective multi-institutional analysis of men undergoing cystoscopy in 4 European departments of urology. Pain perception was assessed with an 11-point numeric rating scale. Pain categories were as follows: no (0 points), mild (1-3), moderate (4-6), and severe pain (7-10). Assessment of pain was before, during cystoscopy, and at days 1, 4, and 7 of follow-up. RESULTS: A total of 300 cystoscopies were analyzed (150 rigid and 150 flexible). Men undergoing flexible cystoscopy were more frequently free of pain (58.7% vs 24%; P <.0001). Mild pain (54% vs 30.7%; P <.0001) and moderate pain (18.7% vs 9.3%; P = .02) were more common with rigid devices. No significant differences were prevalent in severe pain perception (3.3% vs 1.3%; P = .25). Patients, who had previous experience with cystoscopy reported similar pain levels as patients naïve to cystoscopy, regardless if rigid (P = .92) or flexible (P = .26) devices were used. Pain decreased to the baseline during the 1-week follow-up after both, flexible and rigid cystoscopy. In multivariate regression analyses, rigid cystoscopy was an independent predictor for not being pain free (odds ratio [OR] = 0.15; confidence interval [CI] = 0.08-0.28; P <.0001), for experiencing mild pain (OR = 2.57; CI = 1.57-4.19; P <.0001), and for moderate pain (OR = 2.39; CI = 1.13-5.07; P = .02). Severe pain was seldom with both devices, and thus, no statistical difference was found. CONCLUSION: Flexible diagnostic cystoscopy caused less pain than rigid cystoscopy in men. Patient's previous experience with cystoscopy did not influence pain sensation. The type of cystoscope itself was identified as an independent risk factor of pain perception.

Impact of the use of bowel for urinary diversion on perioperative complications and 90-day mortality in patients aged 75 years or older.

OBJECTIVE: A potential strategy to decrease the high complication rate of radical cystectomy (RC) in the elderly is to avoid the use of bowel for urinary diversion. The aim of this study was to address this issue in a multicentre study of patients aged ≥ 75 years. PATIENTS AND METHODS: We performed a retrospective, multicentre study of a consecutive series of patients aged ≥ 75 years who underwent RC for muscle-invasive bladder cancer between 2006 and 2010. Medical, surgical and wound complications were graded according to the modified Clavien-Dindo classification. RESULTS: A total of 256 patients (68% men, mean age 79.6 years) were analysed. 204 (80%) patients received a urinary diversion with use of bowel and 52 (20%) a ureterocutaneostomy (UC). Patients with UC were older (82.0 vs. 78.9 years, p < 0.001) and had a higher ASA score (2.6 vs. 2.3, p = 0.007), while the mean Charlson score was lower (4.2 vs. 5.6, p < 0.001). Patients with UC had a shorter operating time (279 vs. 311 min, p = 0.002) and a shorter period in the intensive care unit (0.9 vs. 2.2 days). The overall rate of severe complications graded as Clavien III-V was significantly lower in the UC group (11.5%) as compared to patients receiving bowel for urinary diversion (25.0%) (p = 0.003). Severe (Clavien grade III-V) medical (3.9 vs. 10.3%) and surgical (2.1 vs. 14.1%) complications were all less frequent in the UC group. Inpatient, 30- and 90-day mortality was 5.8, 7.7 and 17.3% in the UC group as compared to 3.9, 5.9 and 6.9% in the bowel cohort, respectively. CONCLUSION: UC following RC is associated with a lower complication rate in geriatric patients. The constantly increasing cohort of geriatric, multimorbid patients requiring cystectomy might justify reconsideration of this form of diversion.

Perioperative complications and 90-day mortality of radical cystectomy in the elderly (75+): a retrospective, multicentre study.

OBJECTIVE: To assess perioperative complications and 90-day mortality of radical cystectomy (RC) in elderly patients with muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: This is a retrospective, multicentre (n = 11) study of a consecutive series of patients ≥75 years who underwent RC for MIBC between 2006 and 2010. Medical, surgical and wound complications were graded according to the modified Clavien-Dindo classification. RESULTS: A total of 256 patients with a mean age of 79.6 years (range 75.0-86.6) were analysed. Urinary diversion with the use of bowel was performed in 79.5% and ureterocutaneostomy in 20.5%, with a higher proportion in the ≥80 cohort (32.2 vs. 14%; p = 0.001). 41.4% of patients had an uneventful postoperative course (Clavien grade 0) and 26.6% developed severe complications (Clavien grade III-V). In a multivariable regression analysis, the Charlson comorbidity index (odds ratio 1.5 per unit increase; p < 0.001) and the body mass index (odds ratio 1.13 per kg/m(2) increase; p = 0.015) were predictors for the development of complications. The 90-day mortality rate was 9% and the independent correlates thereof were the development of severe medical complications (p = 0.004), the American Society of Anesthesiologists (ASA) score (p = 0.03) and age (p = 0.005). CONCLUSIONS: Morbidity and 90-day mortality of RC in the elderly remain substantial. The interrelation between comorbidity, complication rate and 90-day mortality underlines the need for a comprehensive geriatric assessment of elderly patients with MIBC in whom RC is indicated.

Extranodal extension is a powerful prognostic factor in bladder cancer patients with lymph node metastasis.

BACKGROUND: Lymph node metastasis (LNM) is the most powerful pathologic predictor of disease recurrence after radical cystectomy (RC). However, the outcomes of patients with LNM are highly variable. OBJECTIVE: To assess the prognostic value of extranodal extension (ENE) and other lymph node (LN) parameters. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis of 748 patients with urothelial carcinoma of the bladder and LNM treated with RC and lymphadenectomy without neoadjuvant therapy at 10 European and North American centers (median follow-up: 27 mo). INTERVENTION: All subjects underwent RC and bilateral pelvic lymphadenectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Each LNM was microscopically evaluated for the presence of ENE. The number of LNs removed, number of positive LNs, and LN density were recorded and calculated. Univariable and multivariable analyses addressed time to disease recurrence and cancer-specific mortality after RC. RESULTS AND LIMITATIONS: A total of 375 patients (50.1%) had ENE. The median number of LNs removed, number of positive LNs, and LN density were 15, 2, and 15, respectively. The rate of ENE increased with advancing pT stage (p<0.001). In multivariable Cox regression analyses that adjusted for the effects of established clinicopathologic features and LN parameters, ENE was associated with disease recurrence (hazard ratio [HR]: 1.89; 95% confidence interval [CI], 1.55-2.31; p<0.001) and cancer-specific mortality (HR: 1.90; 95% CI, 1.52-2.37; p<0.001). The addition of ENE to a multivariable model that included pT stage, tumor grade, age, gender, lymphovascular invasion, surgical margin status, LN density, number of LNs removed, number of positive LNs, and adjuvant chemotherapy improved predictive accuracy for disease recurrence and cancer-specific mortality from 70.3% to 77.8% (p<0.001) and from 71.8% to 77.8% (p=0.007), respectively. The main limitation of the study is its retrospective nature. CONCLUSIONS: ENE is an independent predictor of both cancer recurrence and cancer-specific mortality in RC patients with LNM. Knowledge of ENE status could help with patient counseling, clinical decision making regarding inclusion in clinical trials of adjuvant therapy, and tailored follow-up scheduling after RC.

Prognostic value of extranodal extension and other lymph node parameters in patients with upper tract urothelial carcinoma.

PURPOSE: We assessed the prognostic value of extranodal extension and other lymph node parameters in a large multicenter cohort of patients with lymph node metastasis after radical nephroureterectomy. MATERIALS AND METHODS: We retrospectively analyzed the records of 222 patients with lymph node metastasis treated with radical nephroureterectomy for upper tract urothelial carcinoma without neoadjuvant therapy. Each lymph node metastasis was microscopically evaluated for extranodal extension. RESULTS: A median of 4 lymph nodes (IQR 8) was removed. Two lymph nodes (IQR 2) were positive. Lymph node density was 51.3% (IQR 71.7%). Overall 110 patients (49.5%) had extranodal extension, which was associated with more advanced pT stage (p = 0.026). On multivariable analysis extranodal extension was associated with disease recurrence (p = 0.01) and cancer specific mortality (p = 0.013). When stratified by a 30% cutoff, lymph node density was associated with disease recurrence and cancer specific mortality on univariable but not multivariable analysis (p = 0.048 and 0.049, respectively). Adding extranodal extension to a multivariable model including pT stage and tumor architecture improved predictive accuracy for disease recurrence from 70.3% to 74.5% (p <0.001). Adding extranodal extension to a multivariable model including age, pT stage and tumor architecture improved predictive accuracy for cancer specific mortality from 70.6% to 74.4% (p <0.001). CONCLUSIONS: Extranodal extension is a powerful predictor of clinical outcomes in patients with upper tract urothelial carcinoma with lymph node metastasis. While other lymph node parameters seem to have limited clinical value, extranodal extension could help risk stratify patients with upper tract urothelial carcinoma and lymph node metastasis for better counseling and clinical trial design.

Impact of gender on bladder cancer incidence, staging, and prognosis.

INTRODUCTION: While patient gender is an important factor in the clinical decision-making for the management of bladder cancer, there are minimal evidence-based recommendations to guide health care professionals. Recent epidemiologic and translational research has shed some light on the complex relationship between gender and bladder cancer. Our aim was to review the literature on the effect of gender on bladder cancer incidence, biology, mortality, and treatment. METHODS: Using MEDLINE, we performed a search of the literature between January 1975 and April 2011. RESULTS: Although men are nearly 3-4 times more likely to develop bladder cancer than women, women present with more advanced disease and have worse survival. Recently, a number of population-based and multicenter collaborative studies have shown that female gender is associated with a significantly higher rate of cancer-specific recurrence and mortality after radical cystectomy. The disparity between genders is proposed to be the result of a differences exposure to carcinogens (i.e., tobacco and chemicals) as well as reflective of genetic, anatomic, hormonal, societal, and environmental factors. Explanations for the differential behavior of bladder cancer between genders include sex steroids and their receptors as well as inferior quality of care for women (inpatient length of stay, referral patterns, and surgical outcomes). CONCLUSIONS: It is imperative that health care practitioners and researchers from disparate disciplines collectively focus efforts to appropriately develop gender-specific evidence-based guidelines for bladder cancer patients. We must strive to develop multidisciplinary collaborative efforts to provide tailored gender-specific care for bladder cancer patients.
