The assessment of bladder cancer resectability with bimanual palpation: A prospective study in laparoscopy and open cystectomy patients.

PURPOSE: To evaluate the value of examination under anesthesia (EUA) in the assessment of bladder resectability during cystectomy. MATERIALS AND METHODS: This prospective study included consecutive patients undergoing cystectomy for bladder cancer at a single center between June 2017 and October 2020. EUA was conducted before cystectomy by two urologists who assessed the bladder for limited mobility. One examiner was blinded to the imaging results. Soft tissue surgical margin status in the pathological evaluation of a cystectomy specimen served as a measure of resectability. We used multivariable logistic regression models to assess whether EUA performed by blinded or non-blinded examiners is associated with soft tissue positive surgical margins (PSMs) and to calculate the fraction of new information added by such an examination in addition to selected clinical variables. RESULTS: Among the 134 patients analyzed, limited bladder mobility was indicated by the blinded and non-blinded examiners in 23 (17.2%) and 21 (15.7%) cases, respectively. PSMs were identified in 22 (16.4%) patients, more often in patients with limited bladder mobility as assessed by the blinded (odds ratio [OR] 6.7; 95% confidence interval [CI], 1.9-24.2) and non-blinded examiners (OR 12.9; 95% CI, 2.9-57.5). The fraction of new information added by the blinded and non-blinded examiners was 48.6% and 57.7%, respectively. The enrichment of patients who underwent pure laparoscopic cystectomy (n = 102; 76%) and the inclusion of patients for emergent surgery may limit the generalizability of our findings. CONCLUSIONS: The identification of limited bladder mobility during preoperative EUA yielded prognostic information on surgical margin status. Our findings suggest that EUA has the potential to provide valuable insights in the assessment of bladder resectability. However, further research in a larger cohort of patients is warranted to validate and expand on these findings.

Diagnostic accuracy of bimanual palpation in bladder cancer patients undergoing cystectomy: A prospective study.

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.

Artificial urinary sphincter implantation with periprostatic cuff placement for urinary incontinence in men.

Introduction: Artificial urinary sphincter (AUS) implantation is the treatment of choice for male urinary incontinence (UI). The aim of the present study was to evaluate treatment outcomes of UI in men using an AUS with a cuff placed around the prostatic urethra. Material and methods: Forty-three men with preserved prostatic urethra were selected for AUS implantation due to UI. Twenty patients had the cuff implanted around the prostate using the retropubic approach (Group 1), and 23 had the cuff placed around the bulbous urethra (Group 2). Both groups were compared in terms of continence quality as well as intra- and postoperative complications. Results: The groups were comparable with respect to age and duration of follow-up. Median time to complications was 90.3 and 10.7 months in Group 1 and Group 2, respectively (p = 0.007). The complication rate was 40% and 58.3% in Group 1 and 2, respectively (p = 0.001). Complete continence was obtained in 80% of patients from Group 1 and 33.3% of men from Group 2A (p = 0.001). Conclusions: The analysis indicates that cuff placement around the prostatic urethra results in better continence and is characterised by fewer complications. This method is dedicated for patients who have not had the prostate gland removed. Due to the retrospective nature of this analysis and small groups of patients, it is not possible to formulate ultimate recommendations.

Van Velthoven single-knot running suture versus Chlosta's running suture versus single barbed suture V-Loc for vesicourethral anastomosis in laparoscopic radical prostatectomy: a retrospective comparative study.

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.

Novel Classification for Upper Tract Urothelial Carcinoma to Better Risk-stratify Patients Eligible for Kidney-sparing Strategies: An International Collaborative Study.

BACKGROUND: The European Association of Urology risk stratification dichotomizes patients with upper tract urothelial carcinoma (UTUC) into two risk categories. OBJECTIVE: To evaluate the predictive value of a new classification to better risk stratify patients eligible for kidney-sparing surgery (KSS). DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective study including 1214 patients from 21 centers who underwent ureterorenoscopy (URS) with biopsy followed by radical nephroureterectomy (RNU) for nonmetastatic UTUC between 2000 and 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A multivariate logistic regression analysis identified predictors of muscle invasion (≥pT2) at RNU. The Youden index was used to identify cutoff points. RESULTS AND LIMITATIONS: A total of 811 patients (67%) were male and the median age was 71 yr (interquartile range 63-77). The presence of non-organ-confined disease on preoperative imaging (p < 0.0001), sessile tumor (p < 0.0001), hydronephrosis (p = 0.0003), high-grade cytology (p = 0.0043), or biopsy (p = 0.0174) and higher age at diagnosis (p = 0.029) were independently associated with ≥pT2 at RNU. Tumor size was significantly associated with ≥pT2 disease only in univariate analysis with a cutoff of 2 cm. Tumor size and all significant categorical variables defined the high-risk category. Tumor multifocality and a history of radical cystectomy help to dichotomize between low-risk and intermediate-risk categories. The odds ratio for muscle invasion were 5.5 (95% confidence interval [CI] 1.3-24.0; p = 0.023) for intermediate risk versus low risk, and 12.7 (95% CI 3.0-54.5; p = 0.0006) for high risk versus low risk. Limitations include the retrospective design and selection bias (all patients underwent RNU). CONCLUSIONS: Patients with low-risk UTUC represent ideal candidates for KSS, while some patients with intermediate-risk UTUC may also be considered. This classification needs further prospective validation and may help stratification in clinical trial design. PATIENT SUMMARY: We investigated factors predicting stage 2 or greater cancer of the upper urinary tract at the time of surgery for ureter and kidney removal and designed a new risk stratification. Patients with low or intermediate risk may be eligible for kidney-sparing surgery with close follow-up. Our classification scheme needs further validation based on cancer outcomes.

Treatment patterns for lower urinary tract symptoms and overactive bladder in an Eastern European country: a nationwide population-representative survey.

INTRODUCTION: The aim of this study was to establish at the population level the treatment patterns for lower urinary tract symptoms (LUTS) and overactive bladder (OAB) in Poland. MATERIAL AND METHODS: We used data from LUTS POLAND, a survey representative of the entire Polish population classified by age, sex, and place of residence. The treatment patterns we considered were lifestyle changes, physiotherapy, non-prescription drugs, prescription drugs, and surgical treatment. RESULTS: We obtained 6,005 completed interviews. About one-third of respondents who reported LUTS or OAB were seeking treatment, and many of these persons received treatment. Men were more proactive in seeking treatment than women, and men more often received treatment. Management with prescription drugs was the most common treatment modality of LUTS and OAB respondents. There were some disparities in distribution of other treatment options between LUTS and OAB persons, but, disappointingly, non-invasive and low-cost management strategies were rarely reported as being used. Specialists (mainly urologists) provided most of the treatments. We did not identify differences between urban and rural areas in treatment seeking, treatment receiving, and the treatment methods that were used. CONCLUSIONS: In Poland, the scale was low for seeking treatment for LUTS and OAB. As well, there was little reliance on non-invasive and low-cost management strategies for LUTS and OAB. Our findings underline the need for education of patients and physicians about LUTS and OAB, and for greater healthcare and financial resources for LUTS and OAB patients.

Pretreatment Risk Stratification for Endoscopic Kidney-sparing Surgery in Upper Tract Urothelial Carcinoma: An International Collaborative Study.

BACKGROUND: Several groups have proposed features to identify low-risk patients who may benefit from endoscopic kidney-sparing surgery in upper tract urothelial carcinoma (UTUC). OBJECTIVE: To evaluate standard risk stratification features, develop an optimal model to identify ≥pT2/N+ stage at radical nephroureterectomy (RNU), and compare it with the existing unvalidated models. DESIGN, SETTING, AND PARTICIPANTS: This was a collaborative retrospective study that included 1214 patients who underwent ureterorenoscopy with biopsy followed by RNU for nonmetastatic UTUC between 2000 and 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We performed multiple imputation of chained equations for missing data and multivariable logistic regression analysis with a stepwise selection algorithm to create the optimal predictive model. The area under the curve and a decision curve analysis were used to compare the models. RESULTS AND LIMITATIONS: Overall, 659 (54.3%) and 555 (45.7%) patients had ≤pT1N0/Nx and ≥pT2/N+ disease, respectively. In the multivariable logistic regression analysis of our model, age (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.0-1.03, p = 0.013), high-grade biopsy (OR 1.81, 95% CI 1.37-2.40, p < 0.001), biopsy cT1+ staging (OR 3.23, 95% CI 1.93-5.41, p < 0.001), preoperative hydronephrosis (OR 1.37 95% CI 1.04-1.80, p = 0.024), tumor size (OR 1.09, 95% CI 1.01-1.17, p = 0.029), invasion on imaging (OR 5.10, 95% CI 3.32-7.81, p < 0.001), and sessile architecture (OR 2.31, 95% CI 1.58-3.36, p < 0.001) were significantly associated with ≥pT2/pN+ disease. Compared with the existing models, our model had the highest performance accuracy (75% vs 66-71%) and an additional clinical net reduction (four per 100 patients). CONCLUSIONS: Our proposed risk-stratification model predicts the risk of harboring ≥pT2/N+ UTUC with reliable accuracy and a clinical net benefit outperforming the current risk-stratification models. PATIENT SUMMARY: We developed a risk stratification model to better identify patients for endoscopic kidney-sparing surgery in upper tract urothelial carcinoma.

The Performance of Tumor Size as Risk Stratification Parameter in Upper Tract Urothelial Carcinoma (UTUC).

INTRODUCTION: The objective of this study was to evaluate the performance of different tumor diameters for identifying ≥ pT2 upper tract urothelial carcinoma (UTUC) at radical nephroureterectomy. PATIENTS AND METHODS: This was a multi-institutional retrospective study that included 932 patients who underwent radical nephroureterectomy for nonmetastatic UTUC between 2000 and 2016. Tumor sizes were pathologically assessed and categorized into 4 groups: ≤ 1 cm, 1.1 to 2 cm, 2.1 to 3 cm, and > 3 cm. We performed logistic regression and decision-curve analyses. RESULTS: Overall, 45 (4.8%) patients had a tumor size ≤ 1 cm, 141 (15.1%) between 1.1 and 2 cm, 247 (26.5%) between 2.1 and 3 cm, and 499 (53.5%) > 3 cm. In preoperative predictive models that were adjusted for the effects of standard clinicopathologic features, tumor diameters > 2 cm (odds ratio, 2.38; 95% confidence interval, 1.70-3.32; P < .001) and > 3 cm (odds ratio, 1.81; 95% confidence interval, 1.38-2.38; P < .001) were independently associated with ≥ pT2 pathologic staging. The addition of the > 2-cm diameter cutoff improved the area under the curve of the model from 58.8% to 63.0%. Decision-curve analyses demonstrated a clinical net benefit of 0.09 and a net reduction of 8 per 100 patients. CONCLUSION: The 2-cm cutoff appears to be most useful in identifying patients at risk of harboring ≥ pT2 UTUC. This confirms the current European Association of Urology guideline's risk stratification. Tumor size alone is not sufficient for optimal risk stratification, rather a constellation of features is needed to select the best candidate for kidney-sparing surgery.

Neurogenic bladder symptom score: Polish translation, adaptation and validation of urinary disorder-specific instrument for patients with neurogenic lower urinary tract dysfunction.

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.

The Prognostic Value of Tumor Regression Grades Combined With TNM Classification in Patients With Muscle-Invasive Bladder Cancer Who Underwent Neoadjuvant Chemotherapy Followed by Radical Cystectomy.

INTRODUCTION: Tumor regression grades (TRGs) quantify the pathologic response to neoadjuvant chemotherapy (NAC). The aim of the study was to investigate the prognostic value of TRGs in combination with the TNM classification in an independent cohort of patients with muscle-invasive bladder cancer (MIBC) treated with NAC followed by radical cystectomy (RC) in a retrospective setting. PATIENTS AND METHODS: Patients treated with a complete course of NAC followed by RC for MIBC between December 2012 and December 2017 were enrolled in the study. TRGs were determined in RC specimens. Data were collected preoperatively, and the follow-up was continued up to August 2018. Kaplan-Meier curves and the Cox proportional hazards model were used to compare survival probabilities between major responders (no MIBC, < ypT2 and ypN0), partial responders (≥ ypT2 or ypN+ and TRG2), and non-responders (≥ ypT2 or ypN+ and TRG3). RESULTS: A group of 70 patients with a median age of 64 years (interquartile range, 58-67 years) was analyzed. There were 36 major responders, 21 partial responders, and 13 non-responders. In comparison with a major response, a partial response was associated with a hazard ratio of 9.44 (95% confidence interval, 1.10-80.89; P = .04) and non- responders showed a hazard ratio of 17.85 (95% confidence interval, 2.18-145.85; P = .007) for death. CONCLUSIONS: The study confirms the prognostic value of the pathologic response to NAC. Determination of TRGs is straightforward, provides valuable information, and could be easily included in the standard pathologic examination of RC surgical specimen. Prospective studies are needed to establish the role of TRG in routine clinical practice.

Accuracy and prognostic value of variant histology and lymphovascular invasion at transurethral resection of bladder.

OBJECTIVES: To evaluate the concordance rate of lymphovascular invasion (LVI) and variant histology (VH) of transurethral resection (TUR) with radical cystectomy (RC) specimens. Furthermore, to evaluate the value of LVI and VH at TUR for predicting non-organ confined (NOC) disease, lymph node metastasis, and survival outcomes. PATIENTS AND METHODS: Two hundred and sixty-eight patients who underwent TUR and subsequent RC were reviewed. Logistic regression analyses were performed to evaluate the association of LVI and VH with NOC and lymph node metastasis at RC. Cox regression analyses were used to estimate recurrence-free survival (RFS) and cancer-specific survival (CSS). RESULTS: LVI and VH were detected in 13.8 and 11.2% of TUR specimens, and in 30.2 and 25.4% of RC specimens, respectively. The concordance rate between LVI and VH at TUR and subsequent RC was 69.8 and 83.6%, respectively. They were both associated with adverse pathological features such as lymph node metastasis and advanced stage. TUR LVI and VH were both independently associated with lymph node metastasis and TUR VH was independently associated with NOC. On univariable Cox regression analyses, TUR LVI was associated with RFS and CSS while TUR VH was only associated with RFS. Only TUR LVI was independently associated with RFS. CONCLUSION: Detection of LVI is missed in a third of TUR specimens while VH seems more accurately identified. TUR LVI and VH are associated with more advanced disease and LVI predicts disease recurrence. Assessment and reporting of LVI and VH on TUR specimen are important for risk stratification and decision-making.

[Surgical management of severe Peyronie's disease]. / Chirurgiczne leczenie ciezkich postaci choroby Peyronie.

Peyronie's disease (lat. induratio penis plastica) is a process of the fibrotic plaques oand other localized fibrotic conditions have been considered to be the result of an abnormal size, pain and improved penile curvature. At early stages intralesional injections may decrease penile curvature and decrease plaque volume although the exact mechanism of action on Peyronie disease is unknown. In serious cases surgery is recommended, based on ultrasound examination, cavernosography and cavernosometry. There are three mail surgical procedures to correct the curvature in Peyronie's disease: Nesbit plication, plaque excision followed by skin grafting, another autograft or synthetic material, and implantation of a penile prosthesis Aim of this study is to present our experience in surgical treatment of severe stadium in Peyronie's disease. Peyronie plaque was excised in 8 man, previously potent with severe satium of the disease. In every case saphenous autograft replacing excised plaque was used. In every case was not intra and postoperative complications. All patients reported satisfactory cosmetic and functional result. The satisfactory result of the treatment of severe stadium Peyronie disease is based on the surgical method. Saphenous graft is effective, safe and successful technique in our knowledge.
