RESUMO
OBJECTIVES: To prospectively assess the concordance of examination under anesthesia (EUA)-based clinical T stage with pathological T stage and diagnostic accuracy of EUA in patients with bladder cancer undergoing cystectomy. METHODS: Consecutive patients with bladder cancer undergoing cystectomy between June 2017 and October 2020 in a single academic center were included in a prospective study. Two urologists performed EUA (one blinded to imaging) before patients underwent cystectomy. We assessed the concordance between clinical T stage in bimanual palpation (index test) and pathological T stage in cystectomy specimens (reference test). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated with 95% confidence intervals (CIs) to detect or exclude locally advanced bladder cancer (pT3b-T4b) in EUA. RESULTS: The data of 134 patients were analyzed. Given that stage pT3a cannot be palpated, for the nonblinded examiner, T staging in EUA was concordant with pT in 107 (79.9%) patients, 20 (14.9%) cases being understaged in EUA and 7 (5.2%) overstaged. For the blinded examiner, staging was correct in 106 (79.1%) patients, 20 (14.9%) cases being understaged and 8 (6%) overstaged. For the nonblinded examiner, sensitivity, specificity, PPV, and NPV of EUA were 55.9% (95% CI 39.2%-72.6%), 93% (88%-98%), 73.1% (56%-90.1%), and 86.1% (79.6%-92.6%), respectively; for the blinded examiner, they were 52.9% (36.2%-69.7%), 93% (88%-98%), 72% (54.4%-89.6%) and 85.3% (78.7%-92%), respectively. Awareness of imaging results did not have a major impact on EUA results. CONCLUSION: Bimanual palpation should still be used for clinical staging, given its specificity, NPV, and that it could correctly determine bladder cancer T stage in 80% of cases.

Introduction: Radical prostatectomy (RP) is the standard surgical treatment for localized prostate cancer (PCa), with excellent oncologic outcomes; however, complications such as post-prostatectomy incontinence could significantly affect quality of life. Aim: To provide data on long-term urinary functional outcomes of bladder neck preservation (BNP) combined with distal urethral length preservation (DULP) in patients treated with videolaparoscopic prostatectomy. Material and methods: In this retrospective study, data were analysed from 619 consecutive patients who underwent laparoscopic radical prostatectomy (LRP) due to localized prostate cancer between November 2014 and December 2018 in a single tertiary care centre in Poland. Of these patients, 227 had BNP and DULP during the procedure. Urinary continence status was assessed in patients at 3, 6, 12, and 18 months after LRP. Cancer resection was assessed by surgical margin status. Results: In the group with BNP and DULP, urinary continence recurred earlier than it did in the control group up to 3 months after surgery: 204 (89.8%) patients in this group were fully continent compared with 283 (72.2%) in the control group (p < 0.001). The difference was also significant after 6 months (95.1% vs. 80.6%, respectively; p < 0.001). Despite these early promising results, there was no difference in urinary continence recovery after 12 and 18 months. There was also no difference between the 2 groups regarding surgical margin status of the resected tissue. Conclusions: Our study showed that BNP combined with DULP is a safe procedure that helps to improve early urinary continence rates after surgery without altering the risk of positive surgical margin.
RESUMO
INTRODUCTION: The quality of vesicourethral anastomosis (VUA) in laparoscopic radical prostatectomy (LRP) is associated with complications that could significantly affect quality of life. AIM: To compare different types of sutures (Chlosta's versus Van Velthoven versus V-Loc), used for VUA in LRP in terms of complication rates and continence recovery. MATERIAL AND METHODS: Patients who underwent LRP between 2014 and 2018 in a tertiary center were enrolled in the study. Data were extracted from medical records. Urinary continence was assessed at 3, 6, 12 and 18 months after LRP. Propensity score weighted regression models were used to estimate the effect of sutures on outcomes. RESULTS: A sample of 504 patients was analyzed, of which 109 patients underwent Chlosta's suture VUA, 117 patients had Van Velthoven suture VUA, and 278 patients had V-Loc VUA. Median time of anastomosis was 13 (IQR - interquartile range: 10-16) min using Chlosta's suture, 28 (IQR: 24-30) using Van-Velthoven suture and 12 (IQR: 11-16) min using V-Loc suture (p < 0.001). There were no significant differences between groups concerning complications and urinary continence at 12 and 18 months after surgery. The time of urinary continence recovery was on average 19 days (95% CI: 5-33) and 31 days (95% CI: 16-45) shorter during 1 year of observation when the V-Loc suture was used compared to the Van-Velthoven and Chlosta's suture, respectively. CONCLUSIONS: The study showed comparable results considering urinary continence recovery at 12 and 18 months after LRP in all VUA groups. Van Velthoven VUA was more time-consuming and continence recovery was faster in the V-Loc group.
RESUMO
INTRODUCTION: There is no comprehensive and specific questionnaire translated, adapted and validated in the Polish language for evaluating symptoms, quality of life and complications associated with the neurogenic lower urinary tract dysfunction (NLUTD). The aim of this study was to translate, culturally adapt and validate a Polish version of the Neurogenic Bladder Symptom Score (NBSS) for patients who experience NLUTD. MATERIAL AND METHODS: Standardised guidelines and well-established methods were used for translation and cross-cultural adaptation of the NBSS. Adult patients with multiple sclerosis and spinal cord injury completed the NBSS, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the International Prostate Symptom Score (IPSS) and the SF-Qualiveen. Responses were recorded twice within a 14-day period. RESULTS: Two hundred seventy-four Polish-speaking patients with NLUTD were included in the study. Content validity was optimal. Significant relationships between NBSS (Incontinence) and ICIQ-SF, NBSS (Storage and Voiding) and IPSS, and NBSS (Quality of Life) and SF-Qualiveen confirmed good construct/criterion validity. An intercorrelation study revealed that internal consistency was good for the total NBSS and specific domains (Cronbach's alpha >0.7). Test-retest reliability (reproducibility) demonstrated strong stability (intra-class correlation coefficients >0.7 for the total NBSS). No ceiling or floor effects were present. CONCLUSIONS: The Polish NBSS demonstrated good measurement properties for a large cohort of patients with NLUTD. It is a suitable tool to assess NLUTD symptoms, consequences and quality of life. The Polish NBSS will support routine clinical practice of all types of physicians in Poland who care for patients with NLUTD.

INTRODUCTION: The year 2015 brought a major shift in the national health care system in Poland - the diagnosis and treatment of patients with malignant diseases became a priority. Close multidisciplinary collaboration was facilitated to optimize patients' care. The aim of this study was to investigate temporal changes in neoadjuvant chemotherapy (NAC) utilization in patients who underwent radical cystectomy (RC) due to muscle invasive bladder cancer (MIBC) in a single academic center in Poland. MATERIAL AND METHODS: Patients who underwent planned curative RC with bilateral pelvic lymph node dissection between January 2013 and December 2018 in a tertiary care center were included in the study. To assess the response to chemotherapy, tumor regression grades (TRGs) were included into the standard pathological examination of RC specimens. RESULTS: Out of 183 patients enrolled into the study, 105 (57.4%) underwent NAC before RC. Only 1 (4%) out of 25 patients underwent NAC prior to RC in 2013. The percentage of patients who received NAC in subsequent years were: 4% (1/25) in 2013, 36% (9/25) in 2014, 55.3% (21/38) in 2015, 62.9% (21/35) in 2016, 83.9% (26/31) in 2017 and 89.7% (26/29) in 2018 (p-value for trend <0.001). Thirty patients (28.6%) had complete pathological response to NAC (TRG1), 50 patients (47.6%) showed strong response (TRG2) and 25 patients (23.7%) had weak or no response (TRG3). CONCLUSIONS: This study showed an increasing utilization of NAC amongst MIBC patients who underwent RC. Close multidisciplinary collaboration is the key to optimizing perioperative care of patients with MIBC.
RESUMO
INTRODUCTION: The aim of this single centre retrospective study was to analyse the results of second resection (repeat transurethral resection of bladder tumour - reTURBT) after a macroscopically complete resection of T1 urothelial bladder tumour and to identify prognostic factors for absence of residual disease (T0) in the second resection of T1 bladder cancer. MATERIAL AND METHODS: Patients with T1 bladder cancer diagnosed in a macroscopically complete initial resection who underwent second resection within 12 weeks were included into the retrospective analysis. Based on the presence or absence of residual disease, patients were grouped for further analysis. Univariate and multivariable logistic regressions were performed to identify potential prognostic factors. RESULTS: Among the 139 patients who met the inclusion criteria, 96 (69.1%) had no residual disease (T0) and 43 (30.9%) had residual disease in the second resection (including muscle invasive bladder cancer in 2.2%). Adjusted odds ratios (OR) of T0 status obtained from the final model were as follows: detrusor muscle presence in the first resection (OR 3.05; 95% CI 1.12-8.35, p = 0.03), immediate post-operative intravesical mitomycin C administration after the first TURBT (OR 2.52, 95% CI 1.12-5.68; p = 0.03) and primary bladder cancer setting (OR 2.45, 95% CI 1.10-5.47; p = 0.03). CONCLUSIONS: Our results add evidence regarding the importance of detrusor muscle presence in the first TURBT. Identification of predictors of T0 status at second resection could help design prospective studies assessing the possibility to avoid re-resection in selected patients with T1 bladder cancer without compromising oncological outcomes.
RESUMO
INTRODUCTION: Even though the survival benefit of neoadjuvant chemotherapy (NAC) in the treatment of muscle invasive bladder cancer (MIBC) is well established, NAC has not been widely used in Poland until recently. The aim of our study was to evaluate the utilization of NAC and its association with survival in MIBC. MATERIAL AND METHODS: Patients who underwent radical cystectomy (RC) for MIBC between December 2012 and December 2017 were included in the study. Data were collected in the perioperative period and long-term observation was continued up to August 2018. Kaplan-Meier curves were used to estimate the probability of survival. RESULTS: A sample of 155 patients with a median age of 65 (IQR: 60-69) years was analyzed. In this group, 79 patients (51%) were treated with NAC prior to RC. Patients in the NAC+RC group were younger, more often had a positive smoking history, and had lower preoperative levels of hemoglobin, white blood cells and C-reactive protein. A 90-day complication rate and mortality were similar in both groups and in the entire cohort were equal to 64.5% and 5.2%, respectively. The overall survival (OS) was on average 150 days longer in the RC+NAC group compared to the RC-only group when patients were followed-up for 3 years (95%CI:3 4 - 267; p = 0.011). CONCLUSIONS: We demonstrated a high utilization of NAC at our institution. The use of NAC was associated with a better prognosis than RC alone and was not associated with an increased morbidity or mortality. Our results support the use NAC as a safe and effective treatment modality in MIBC.
RESUMO
BACKGROUND AND OBJECTIVE: Urological diseases represent a significant health issue worldwide. Presented study aimed at assessing current urological knowledge and confidence in performing urological diagnostic and therapeutic procedures among medical students at Jagiellonian University Medical College in Poland and compare it on different stages of the undergraduate medical education. MATERIAL AND METHODS: We designed an anonymous survey distributed among Polish students from 1st to 6th year of medical studies, before and after clinical urology course. Questions concerned general urological knowledge, prostate diseases, erectile dysfunction, and self-reported practical urological skills. RESULTS: Overall, 437 respondents participated in the survey. Mean total test score in our study group was 50.08%, mean general urological knowledge score was 53.44%, mean prostate diseases knowledge score was 55.43%, mean erectile dysfunction score was 36% and mean practical skills score was 45.83%. Mean total test score increased with consecutive years of studies (R = 0.58; p <0.001). The risk of an above average total test score was significantly influenced by the urology course (OR = 7.95, 95%CI = 1.81-34.84, p = 0.006) and the year of medical studies (4th-6th vs. 1st-3rd) (OR = 5.16, 95%CI = 3.41-7.81, p <0.001). Practical skills score above average was significantly more frequent in the group after the urology course (OR = 6.75, 95%CI = 1.54-29.58, p = 0.011). CONCLUSIONS: Results of this study reveal low mean scores obtained by students, even after completing the urology course, which implies that curriculum requires further development. Urological knowledge and self-assessed practical skills increased with years of medical education. The urology course improved the score obtained in our survey, both in terms of total test score and practical skills.

STUDY DESIGN: Radiographic analysis of spinopelvic morphology and posterior element dysplasia in spondyloptosis. SUMMARY OF BACKGROUND DATA: Spondylolisthesis treatment protocols are based on age, symptomatology, and slippage degree. Spinopelvic morphology and dysplasia can determine progression. Frequency of two denominators of high-grade spondylolisthesis-degree of dysplasia and spinopelvic morphology-is unknown. OBJECTIVES: To determine common radiographic denominators of spondyloptosis-degree of posterior bony hook dysplasia and spinopelvic morphology-as prognostic factors for spondylolisthesis progression. METHODS: Patients with spondyloptosis were reviewed. Bony dysplasia at lumbosacral junction was graded. Pelvic incidence and sacral kyphosis were measured. RESULTS: A total of 53 patients had a mean sacral kyphosis of 56 degrees and pelvic incidence of 76 degrees; 62% of patients had posterior element dysplasia. CONCLUSION: Prognostic factors for spondylolisthesis progression, such as percent of slippage, do not identify lower-grade slips at risk for progression. Progression is linked to increased shear stress across the lumbosacral junction and inability to resist it. Increased stress is related to increased verticality of the lumbosacral joint, which is individually predetermined by pelvic incidence and sacral anatomy. Pelvic incidence is fundamental in determining sagittal spine curvature required for economic spinopelvic balance. Pelvic incidence is independent of adaptive changes in higher-grade spondylolisthesis. Pelvic incidence in our spondyloptosis series (76 degrees) is higher than in normal (48.2-53.2 degrees ) and low-grade spondylolisthesis (64.5 degrees). Posterior element dysplasia decreases mechanical resistance to lumbosacral shear stress. Incidence of dysplasia in our series (62%) is higher than that reported in low-grade spondylolisthesis. Analysis of pelvic incidence and posterior element dysplasia may aid in estimation of risk for progression of spondylolisthesis.
