Abstract
BACKGROUND Patients with prostate-specific antigen (PSA) persistence are at the increased risk of disease progression. The aim of our study was to evaluate the impact of early salvage therapy on oncological outcomes in patients with persistent PSA after radical prostatectomy (RP). METHODS Within a single tertiary centre database, we identified men with persistent (≥ 0.1 ng/ml) versus undetectable (< 0.1 ng/ml) PSA 4-8 weeks after RP for high-risk prostate cancer (HRPCa). The cumulative incidence function was used to estimate cancer-specific survival (CSS) and clinical progression-free survival (CPFS). The Kaplan-Meier method was used to estimate overall survival (OS). The effects on oncological outcomes of salvage radiotherapy (SRT) ± androgen deprivation therapy (ADT) vs. ADT monotherapy were tested in the subgroup of patients with persistent PSA. RESULTS Of 414 consecutive patients who underwent RP for HRPC, 125 (30.2%) had persistent PSA. Estimated 10-year CPFS, CSS and OS for men with persistent vs. undetectable PSA were 63.8% vs. 93.5%, 78.5% vs. 98.3% and 54% vs. 83.2% (all p < 0.0001), respectively. In men with persistent PSA, ADT alone was associated with higher risk (hazard ratio (HR) for worse CSS (HR 3.9, p = 0.005) and OS (HR 4.7, p < 0.0001) but not for CP (HR 1.6, p = 0.2) when compared with SRT ± ADT. CONCLUSION In patients who underwent RP for HRPCa, persistent PSA was associated with poor oncological outcomes. Early SRT ± ADT resulted in significantly improved CSS and OS in men with persistent PSA comparing with early androgen deprivation monotherapy.

Abstract
Simple Summary The current prostate cancer guidelines recommend performing the first prostate-specific antigen measurement at three months after radical prostatectomy. However, at an earlier measurement, persistence (≥0.1 ng/mL) of this biomarker could be found in up to 30% of cases, depending on the prostate cancer risk factors. Recent reports have demonstrated an increasing interest in prostate-specific antigen persistence as a possible additional predictor of disease progression and cancer-specific survival. However, the data remain scant, with weak evidence. We assessed the relationship between prostate-specific antigen persistence and long-term oncological outcomes within prostate cancer risk groups. We found that persistence of this biomarker could be used as an independent predictor of worse long-term outcomes in high-risk prostate cancer patients, while in intermediate-risk patients, this parameter significantly predicts only biochemical recurrence and has no impact on the outcomes in low-risk patients. Abstract Objective: To assess the significance of prostate-specific antigen (PSA) persistence at the first measurement after radical prostatectomy (RP) on long-term outcomes in different prostate cancer risk groups. Methods: Persistent PSA was defined as ≥0.1 ng/mL at 4–8 weeks after RP. Patients were stratified into low-, intermediate- and high-risk groups, according to the preoperative PSA, pathological stage, grade group and lymph nodes status. The ten-year cumulative incidence of biochemical recurrence (BCR), metastases, cancer-specific mortality (CSM) and overall mortality (OM) were calculated in patients with undetectable and persistent PSA in different PCa-risk groups. Multivariate regression analyses depicted the significance of PSA persistence on each study endpoint. Results: Of all 1225 men, in 246 (20.1%), PSA persistence was detected. These men had an increased risk of BCR (hazard ratio (HR) 4.2, p < 0.0001), metastases (HR: 2.7, p = 0.002), CRM (HR: 5.5, p = 0.002) and OM (HR: 1.8, p = 0.01) compared to the men with undetectable PSA. The same significance of PSA persistence on each study endpoint was found in the high-risk group (HR: 2.5 to 6.2, p = 0.02 to p < 0.0001). In the intermediate-risk group, PSA persistence was found as a predictor of BCR (HR: 3.9, p < 0.0001), while, in the low-risk group, PSA persistence was not detected as a significant predictor of outcomes after RP. Conclusions: Persistent PSA could be used as an independent predictor of worse long-term outcomes in high-risk PCa patients, while, in intermediate-risk patients, this parameter significantly predicts only biochemical recurrence and has no impact on the outcomes in low-risk PCa patients.

Abstract
Simple Summary For prostate cancer patient, information on risk of long-term cancer-specific and other-cause mortality is essential to avoid over- and undertreatment. Patient stratification to low-, intermediate-, and high-risk groups has been used for decades. However, recent evidence has shown that such stratification is not optimal and outcomes differ widely, especially in high-risk prostate cancer patients. Gleason score grading is an important factor for the prediction of cancer-specific survival and has been included in all prostate cancer risk stratification models. Moreover, this parameter could be used as an independent predictor. Recently proposed grade group model demonstrated good predictive probability on short-term outcomes. However, there is a lack of data regarding long-term cancer-specific survival. In the presented study, we analyzed long-term oncological outcomes in different grade groups. Detected ratio between cancer-specific and other-cause mortality could be very informative and helpful in prostate cancer patient risk stratification and more precise clinical decision making. Abstract Objective: To assess the risk of cancer-specific mortality (CSM) and other-cause mortality (OCM) using post-operative International Society of Urological Pathology Grade Group (GG) model in patients after radical prostatectomy (RP). Patients and Methods: Overall 1921 consecutive men who underwent RP during 2001 to 2017 in a single tertiary center were included in the study. Multivariate competing risk regression analysis was used to identify significant predictors and quantify cumulative incidence of CSM and OCM. Time-depending area under the curve (AUC) depicted the performance of GG model on prediction of CSM. Results: Over a median follow-up of 7.9-year (IQR 4.4-11.7) after RP, 235 (12.2%) deaths were registered, and 52 (2.7%) of them were related to PCa. GG model showed high and stable performance (time-dependent AUC 0.88) on prediction of CSM. Cumulative 10-year CSM in GGs 1 to 5 was 0.9%, 2.3%, 7.6%, 14.7%, and 48.6%, respectively; 10-year OCM in GGs was 15.5%, 16.1%, 12.6%, 17.7% and 6.5%, respectively. The ratio between 10-year CSM/OCM in GGs 1 to 5 was 1:17, 1:7, 1:2, 1:1, and 7:1, respectively. Conclusions: Cancer-specific and other-cause mortality differed widely between GGs. Presented findings could aid in personalized clinical decision making for active treatment.

Abstract
OBJECTIVE To investigate whether the new prostate cancer grade groups model provides significant predictive value and better patient stratification on tumor progression after radical prostatectomy compared with the former Gleason grading models. METHODS Men treated at a tertiary center by radical prostatectomy between 2005 and 2017 were analyzed. The outcomes of interest were clinical progression-free and cancer-specific survival. Multivariate Cox regression analysis, C-index and decision curve analysis were carried out using three-tier (Gleason score 6, 7 and 8-10), four-tier (Gleason score 6, 7, 8 and 9-10) and new grade groups model. RESULTS In total, 1759 men were included in the analysis. At a median of 87 months (interquartile range 51-134 months) of follow up, clinical progression was detected in 78 (4.4%) and cancer-related death in 42 (2.4%) patients. The hazard ratio of clinical progression-free was 2.3, 5.7, 5.2 and 29.5; the hazard ratio of cancer-specific survival was 1.7, 3.2, 4.8 and 11.8 in the grade groups 2-5, relative to grade group 1, respectively. The grade groups model had higher C-index in comparison with four- and three-tier grading models for clinical progression-free survival 0.88 versus 0.85 versus 0.83 and for cancer-specific survival 0.82 versus 0.80 versus 0.80, respectively. In the decision curve analysis, the grade groups model shows marginally better net benefit on clinical progression-free and cancer-specific survival. CONCLUSIONS The new model shows better performance in comparison with former Gleason grading models on the prediction of long-term oncological outcomes.

Abstract
Introduction: Despite progress in the field of high-risk localized prostate cancer (HRPCa) treatments, high-risk patients treated with curative intent are at increased risk of biochemical recurrence, metastatic progression and cancer-related death. The optimal treatment strategy remains a topic of debate. This review provides an overview of the current and investigational therapeutic options for HRPCa.Areas covered: A PubMed search was performed for papers on the current perspectives on the multimodality treatment of HRPCa. We focus on both primary local treatment as well as systemic treatment options. Finally, relevant ongoing trials focusing on systemic treatments (including [neo]adjuvant treatments) enrolling at least 50 patients were retrieved, to highlight ongoing research and treatment optimization.Expert opinion: Disease progression in HRPCa patients is driven by local tumor extension and subclinical metastases. Therefore, the main treatment concept is a multimodal approach targeting the primary tumor with extended surgery or RT with long-term ADT and simultaneously targeting micro-metastatic deposits. However, there is still room for optimization. Upcoming clinical trials comparing surgery versus RT as local treatment, trials with (neo)adjuvant chemotherapy or androgen receptor signaling inhibitors will likely change the treatment landscape. However, a multimodal treatment strategy will stay as the cornerstone in the treatment of HRPCa.

Abstract
Introduction The aim of our study was to evaluate the external validity of the online Memorial Sloan Kettering Cancer Center (MSKCC) nomogram as a predictor for pelvic lymph node invasion (LNI) in men who underwent radical prostatectomy (RP) with pelvic lymph node dissection (PLND). Material and methods The study cohort consisted of 679 men with clinically localized prostate cancer (PCa) who underwent RP with PLND between 2005 and 2017. The area under curve (AUC) of the receiver operator characteristic analysis was used to quantify the accuracy of MSKCC nomogram to predict LNI. The specificity, sensitivity and negative predictive value were calculated to assess LNI probability cut-off. Results A total of 81 of 679 patients had LNI (11.9%). The AUC of MSKCC nomogram was 79%. Using the cut-off value of 7% (sensitivity 88.9%, specificity 45.2% and NPV 96.8%) a PLND could be omitted in 41% (279/679) of men. However, 3.2% (9/279) of men with LNI would be missed. MSKCC nomogram showed good calibration characteristics and high net benefit at decision curve analysis. Conclusions MSKCC nomogram in patients with PCa undergoing PLND has 79% discriminated accuracy for prediction of LNI in our cohort. Using a 7% nomogram cut-off, roughly 40% of men would be spared PLND with minimal risk to miss LNI.

Abstract
Pelvic floor muscles (PFMs) play a crucial role in urinary continence. Therefore, training the PFMs remains the most popular conservative treatment for urinary incontinence (UI). The effect of training other body muscles on the PFMs is unclear and mostly hypothetical. The objective of our study was to evaluate the effectiveness of postoperative diaphragm muscle, abdominal muscle and PFM training on PFM strength (PFMS) and endurance (PFME) as well as on UI in men after radical prostatectomy (RP). Per-protocol PFMS, PFME and urine loss measurements were performed at 1, 3, and 6 months postoperatively. The primary endpoints were PFMS and PFME differences among the study groups. The secondary endpoint was the correlation between UI and PFMS and PFME. In total, 148 men were randomized to the treatment groups. An increase in PFMS and PFME was observed in all groups compared to baseline (p < 0.001). The greatest difference in PFMS was in the PFM training group, but diaphragm training had the best effect on PFME. The highest (from moderate to strong) correlation between UI and PFME and PFMS (r = −0.61 and r = −0.89, respectively) was observed in the diaphragm training group. Despite different but significant effects on PFMS and PFME, all rehabilitation-training programmes decreased UI in men after RP.

Abstract
PURPOSE The purpose of this study was to describe the level of moral distress experienced by nurses, situations that most often caused moral distress, and the intentions of the nurses to leave the profession. METHODS A descriptive, cross-sectional, correlational design was applied in this study. Registered nurses were recruited from five large, urban Lithuanian municipal hospitals representing the five administrative regions in Lithuania. Among the 2,560 registered nurses, from all unit types and specialities (surgical, therapeutic, and intensive care), working in the five participating hospitals, 900 were randomly selected to be recruited for the study. Of the 900 surveys distributed, 612 questionnaires were completed, for a response rate of 68%. Depending on the hospital, the response rate ranged from 61% to 81%. Moral distress was measured using the Moral Distress Scale-Revised (MDS-R). The MDS-R is designed to measure nurses' experiences of moral distress in 21 clinical situations. Each of the 21 items is scored using a Likert scale (0-4) in two dimensions: how often the situation arises (frequency) and how disturbing the situation is when it occurs (intensity). On the Likert scale, 0 correlates to situations that have never been experienced, and 4 correlates to situations that have occurred very often. RESULTS Among the 612 participants, 206 (32.3%) nurses reported a low level of moral distress (mean score 1.09); 208 (33.9%) a moderate level of distress (mean score 2.53), and 207 (33.8%) a high level of distress (mean score 3.0). The most commonly experienced situations that resulted in moral distress were as follows: "Carrying out physician's orders for what I consider to be unnecessary tests and treatments" (mean score 1.66); "Follow the family's wishes to continue life support even though I believe it is not in the best interest of the patient" (mean score 1.31); and "Follow the physician's request not to discuss the patient's prognosis with the patient or family" (mean score 1.26). Nurses who had a high moral distress level were three times more likely to consider leaving their position compared with respondents who had a medium or low moral distress level (8.7% and 2.9%, respectively; p < .05). CONCLUSIONS Our findings provide evidence on the association between moral distress and intention to leave the profession. Situations that may lead health professionals to be in moral distress seem to be mainly related to the unethical work environment. CLINICAL RELEVANCE The findings of this study reported that moral distress plays a role in both personal and organizational consequences, including negative emotional impacts upon employees.

Abstract
Objective: The aim of our study was to evaluate the impact of time until biochemical recurrence (BCR) after radical prostatectomy (RP) without neo- or adjuvant treatment on clinical progression (CP) and cancer-related death (CRD) in high-risk prostate cancer (HRPCa) patients. Materials and methods: A total of 433 men with clinically HRPCa treated between 2001 and 2017 were identified. HRPCa was defined as clinical stage ≥T2c and/or biopsy Gleason score (GS) ≥8 and/or preoperative prostate specific antigen (PSA) value ≥20 ng/ml. Exclusion criteria were neo- or adjuvant treatment and incomplete pathological or follow-up data. BCR was defined as two consecutive PSA values ≥0.2 ng/ml after RP. CP was identified as skeletal lesions, local or loco-regional recurrence. CRD was defined as death from PCa. All men were divided into two groups according to BCR. The chi-square and t-tests were used to compare baseline characteristics between groups. Biochemical progression free survival (BPFS), clinical progression free survival (CPFS), and cancer-specific survival (CSS) rates were estimated using Kaplan-Meier analysis. Patients with detected BCR were analyzed for prediction of CP and CRD with respect to time until BCR. The impact of baseline parameters on BCR, CP, and CRD was assessed by Cox regression analysis. Results: BCR, CP, and CRD rates were 47.8% (207/433), 11.3% (49/433), and 5.5% (24/433), respectively. Median (quartiles) time of follow-up after RP was 64 (40-110) months. Ten-year BPFS rate was 34.2%; CPFS, 81%; and CSS, 90.1%. Men with detected BCR were analyzed for prediction of CP and CRD with respect to time until BCR. The most informative cutoff for time from RP until CP and CRD was ≤ 1 year (p < 0.008). According to this cutoff, men were divided into two groups: BCR detected within 1 year and after a 1-year period. Ten-year CPFS was 49.8% in men with early BCR vs. 81.1% in men with late BCR; CSS was 70.9 vs. 92.8% (p = 0.001). Multivariable analysis confirmed that time until BCR within 1 year predicts CP (p = 0.005) and CRD (p = 0.03). Conclusions: Early BCR is associated with poorer oncological outcomes. The presented results may help both to improve follow-up strategy and opt for more aggressive multimodal treatment of HRPCa in men with very early BCR.

Abstract
Objective: To investigate the relationship between the new International Society of Urological Pathology (ISUP) grading system, biochemical recurrence (BCR), clinical progression (CP) and cancer related death (CRD) after open radical prostatectomy (RP) and determine whether the 2014 ISUP grading system influences the concept of high-risk prostate cancer (HRPCa). Patients and Methods: A total of 1,754 men who underwent RP from 2005 to 2017 were identified from a database at a single tertiary institution. Histopathology reports were reassessed according to the 2014 ISUP grading system. All preoperative, pathological, and clinical follow-up data were obtained. Univariable and multivariable Cox regression, Kaplan-Meier and log-rank analyses were performed. Results: At a median (quartiles) follow-up of 83 (48-123) months, 446 men (25.4%) had BCR, 77 (4.4%) had CP and 39 (2.2%) died from cancer. Grade groups 1, 2, 3, 4, and 5 were detected in 404 (23%), 931 (53.1%), 200 (11.4%), 93 (5.3%), and 126 (7.2%), respectively. 10-year biochemical progression free survival difference between Grade group 3 and 4 was minor but significant (log-rank p = 0.045). There was no difference between Grade groups 3 and 4 comparing 10-year clinical progression free and 10-year cancer specific survival: p = 0.82 and p = 0.39, respectively. Group 5 had the worst survival rates in comparison with other groups (from p < 0.005 to p < 0.0001) in all survival analyses. Pathological stage (hazard ratio (HR) 2.6, p < 0.001), positive surgical margins (HR 2.2, p < 0.0001) and Grade group (HR 10.4, p < 0.0001) were independent predictors for BCR. Stage and Grade group were detected as independent predictors for CP-HR 6.0, p < 0.0001 and HR 35.6, p < 0.0001, respectively. Only Grade group 5 (HR 12.9, p = 0.001) and pT3b (HR 5.9, p = 0.001) independently predicted CRD. Conclusions: The new ISUP 2014 grading system is the most significant independent predictor for BCR, CP, and CRD. Grade group 3 and 4 had similar long-term disease progression survival rates and could potentially be stratified in the same risk group. High-risk cancer associated only with group 5.

Abstract
Introduction The aim of this study was to describe age- related prostate cancer (PCa) characteristics in men after radical prostatectomy (RP). Material and methods There were 2,373 men who underwent RP for clinically localized PCa between 2002 and 2017 and had complete data that were included into the study. Among them, 315 (13.3%) men aged ≤55 years (GR-1), 1,098 (46.3%) men aged between 56 to 65 years (GR-2) and 960 (40.4%) men aged older than 65 years (GR-3) were identified. All preoperative and pathological parameters were compared between all three groups and between each group separately. High-risk prostate cancer (HRPCa) cases were analyzed separately. Regression analysis was used to evaluate the impact of age on cancer aggressiveness. Result Clinical stage (cT), biopsy Gleason score and D'Amico risk groups were different comparing age-related study groups (all p <0.01), respectively. Preoperatively cT1 and Gleason 6 were in the highest rate for GR-1 in comparison with GR-3: 35.9 vs. 27.1%, p = 0.003 and 65.1% vs. 56.7%, p = 0.008, respectively. Analyzing pathological parameters, only Gleason 9–10 was different between GR-1 and GR-3–3.8 vs. 7.6%, p = 0.02. There were 921 (38.8%) HRPCa cases identified. Age was a significant predictor for HRPCa (p = 0.019) in the regression analysis. The oldest men (GR-3) had up to 1.5 fold increased risk for HRPCa detection in comparison with the youngest one (p = 0.008, HR1.44. 95% CI 1.098–1.87). Conclusions Younger, ≤55-year-old men, are more likely to present with less aggressive clinical and pathological PCa features in comparison with the older ones. Increasing age has a significant influence on HRPCa detection after RP.

Abstract
Paediatric kidney transplantation into adult recipients is a well-recognised technique. However, there are different opinions regarding two methods of transplantation. These two opinions are single kidney transplantation (SKT) and en bloc kidney transplantation (EBKT) from donors up to 20 kg. We are reporting the first successful en bloc kidney transplantation from a small, paediatric donor into an adult recipient in our institution and discussing the appropriate recent literature regarding possible concerns using this technique. Despite the fact that paediatric donors are uncommon and surgical experiences are limited, en bloc kidney transplantation can be performed successfully and could be used to expand the donor pool.

Abstract
PURPOSE High-grade prostatic intraepithelial neoplasia (HGPIN) is a potential precursor of prostate cancer (PCa), and patients with HGPIN are at high risk for PCa development. Objective of our study was to evaluate the efficacy of dutasteride 0.5 mg in PCa prevention among men with isolated HGPIN on biopsy. METHODS This prospective, randomized, phase III, open-label 3-year trial assessed dutasteride versus active surveillance in patients with HGPIN. Patients were randomized to dutasteride 0.5 mg daily or active surveillance. Per-protocol prostate biopsies were performed at 6, 12, 24, and 36 months until cancer detection or study end. The primary end point was cancer-free survival (CFS). An intention-to-treat analysis was done for patients who underwent at least one per-protocol biopsy. An efficacy analysis was done for patients who completed the study. CFS was evaluated using Kaplan-Meier and log-rank analysis. RESULTS In total, 220 men were randomized (dutasteride, n = 107; surveillance, n = 113). PCa was detected in 47.6: 49.1 % in the surveillance group and 45.9 % in the treatment group (p = 0.66). The detected PCa differentiation by Gleason score (GS) was GS 6 in 76.9 %, GS 7 in 19.8 %, and GS ≥ 8 in 3.3 %, with no difference between groups. The 3-year PCa-free survival was 43.6 % in the surveillance and 49.6 % in the dutasteride group (log rank p = 0.57). Limitations include a relatively high non-adherence rate, open-label design, and baseline sextant biopsy scheme. CONCLUSIONS Dutasteride 0.5 mg for 3 years did not lower the PCa detection rate but did not worsen detected PCa characteristics in men with HGPIN.

Abstract
BACKGROUND Fournier gangrene (FG) is a fulminant necrotizing infection of the perineal, perianal, and periurethral tissues. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) scale is used for diagnosis of necrotizing fasciitis. However, data on its relevance and usefulness in FG are lacking. The aim of this study was to evaluate the utility of the LRINEC scale in predicting the outcome of FG. METHODS This retrospective case study included 41 patents with FG treated at our institution from 2000 to 2013. The patients were divided into survivors and non-survivors. RESULTS The mortality rate was 22%. The median age (75 vs. 62.5 y; p = 0.013), rate of co-existing diabetes mellitus (66.7% vs. 3.1%; p < 0.001), and median affected skin surface (4% vs. 1%; p < 0.001) were greater in the non-survivors. Seven of nine patients (77.8%) who did not survive (compared with 37.5% who survived) had a polymicrobial infection (p = 0.032). Of all the causative pathogens isolated, Proteus mirabilis was more common in non-survivors (55.6% vs. 6.3%; p = 0.001). The median calculated LRINEC score for survivors was 5 compared with 10 for the non-survivors (p < 0.001). Regression analysis showed that all the aforementioned variables, except for polymicrobial culture, were significant risk factors for predicting death. The area under the receiver operating characteristic curve for the LRINEC score was the highest, 0.976 (95% confidence interval 0.872-0.999; p < 0.0001), and the cut-off value was ≥9 with 93.7% specificity and 100% susceptibility for the prediction of a lethal outcome. CONCLUSIONS The LRINEC score could be used for prediction of disease severity and outcomes. A threshold of 9 could be a high-value predictor of death during the initial evaluation of patients with FG.

Abstract
Introduction Transurethral resection of the prostate (TURP) still remains the most popular surgical treatment for patients with lower urinary tract symptoms. However, in some patients, the improvement of symptoms after TURP is insufficient. The aim of our study was to evaluate the impact of the resected prostate tissue weight (RPTW) on the improvement of symptoms (IPSS), quality of life (QoL), and voiding function after TURP. Material and methods The study included 89 men who had undergone TURP in our institution. IPSS, QoL, post–voiding residual urine volume (PVR) and Qmax were recorded before the operation and six months after TURP. The total prostate volume (TPV) and transition zone volume (TZV) were measured before the operation by transrectal ultrasound. The impact of RPTW, RPTW/TZV ratio, and RPTW/TPV ratio were analyzed according to the efficacy of TURP. Results The mean Qmax after TURP increased by 10.15 mL/s, IPSS decreased by 16.7 points, QoL increased by 3.57 points, and PVR decreased by 95.3 mL. According to Qmax, the treatment was effective in 74.2%, according to IPSS, in 91%, and according to QoL, in 74.2% of patients. The ROC analysis demonstrated that RPTW/TZV and RPTW/TPV ratios were the most significant predictors of obtaining favorable results. Survival analysis (life table) shows that in order to achieve 50% improvement on Qmax, QoL, and IPSS, more than 30–35% of TPV and more than 60% of the TZV should be removed. Conclusions The efficacy of the TURP at short term follow-up depends on the completeness of the resection.

Abstract
OBJECTIVE The aim of the study was to identify the risk of unfavourable disease (≥ pT3 and/or Gleason score ≥ 7) in radical prostatectomy (RP) specimens and biochemical progression-free survival (BPFS) after RP in patients with low-risk prostate cancer detected by D'Amico criteria before surgery. MATERIAL AND METHODS Between 2004 and 2007, 690 men underwent prostate biopsy and RP at a single university hospital. Of those, 248 patients (35.9%) had low-risk prostate cancer criteria. The endpoints of the study were detection of low-risk (pT2 and Gleason score ≤ 6) or unfavourable (≥ pT3 and/or Gleason score ≥ 7) prostate cancer, and BPFS. The risk of progression was analysed using multivariate Cox regression model and BPFS was established using Kaplan-Meier analysis. RESULTS The median follow-up was 60 months (1-112 months). pT3 was detected in 14.1%, and Gleason score ≥ 7 in 32.7% of patients. Unfavourable prostate cancer was detected in 37.5% of patients. Overall biochemical relapse rate was 13.6%. The estimated probability of 3-, 5- and 8-year BPFS for all study patients was 90.6%, 88.1% and 77.9%, respectively. Eight-year BPFS was 83.3% for low-risk prostate cancer and 68.2% for unfavourable prostate cancer (p = 0.007). Positive surgical margins (p = 0.0001) and postoperative Gleason score (p = 0.023) were the most significant predictors of biochemical relapse in Cox regression analysis. CONCLUSIONS The D'Amico criteria may underestimate potentially aggressive prostate cancer in up to 37.5% of patients. Consequently, caution is recommended when the decision concerning the treatment modality is based on D'Amico criteria alone.

Abstract
OBJECTIVE The aim of our study was to compare long-term oncological outcomes following nephron-sparing surgery (NSS) and radical nephrectomy (RN) for renal cell carcinoma (RCC) 4 to 7 cm in diameter. MATERIAL AND METHODS The study included patients who underwent RN or NSS for RCC 4 to 7 cm in diameter between 1998 and 2009. The studied groups were compared with respect to the patients' age, sex, physical status according to the American Society of Anesthesiologists Physical classification, histological type, stage, tumor size, grade, duration of the operation, and complications. Survival was established using the Kaplan-Meier method. The risk factors for survival were analyzed using a multivariate Cox regression model. RESULTS During the study, 351 patients underwent surgery: 317 patients (90.3%) underwent RN, and 34 (9.7%), NSS. The compared groups differed with respect to tumor size (P=0.001) and stage (P=0.006). The overall estimated 12-year survival was 53.7% after RN and 55.2% after NSS (log-rank test P=0.437). The 12-year cancer-specific survival in the RN and NSS groups was 69.6% and 80.6%, respectively (log-rank test P=0.198). Pathological stage and patients' age were the major factors affecting both overall and cancer-specific survival. The type of surgery (NSS or RN) had no effect on survival. CONCLUSIONS Our study showed that nephron-sparing surgery is a safe technique compared with radical nephrectomy that ensures good oncological control in the treatment of renal cell carcinoma measuring 4 to 7 cm and may be proposed as the treatment of choice for renal tumors not only up to 4 cm, but also 4 to 7 cm in size.

Abstract
Objectives Prostate cancer Gleason score 6 is the most common score detected on prostatic biopsy. We analyzed the clinical parameters that predict the likelihood of Gleason score upgrading after radical prostatectomy. Methods The study population consisted of 241 patients who underwent radical retropubic prostatectomy between Feb 2002 and Dec 2007 for Gleason score 6 adenocarcinoma. The influence of preoperative parameters on the probability of a Gleason score upgrading after surgery was evaluated using multivariate logistic regression and ROC curves. Results Gleason score upgrade was found in 92 of 241 patients (38.2%). Multivariate logistic regression analysis showed that only percentage of cancer in dominant lobe and prostate weight were significant predictors for Gleason score upgrading (p = 0.043 and p = 0.006, respectively). ROC curves showed that prostate weight and PSA density were only two independent significant parameters for prediction of upgrade (AUC – 0.634, p <0.0001 and 0.604, p = 0.006, respectively). Gleason score upgrading was observed to be accompanied by significantly higher rates of extra prostatic extension (p <0.001) and seminal vesicle invasion (p = 0.002). Conclusions Almost forty percent of tumors graded Gleason 6 at biopsy are Gleason 7 at surgery. Upgraded tumors significantly associated with adverse pathological features. The probability of Gleason score upgrade can be predicted using prostate weight and PSA density as independent parameters.

Abstract
INTRODUCTION The aim of this study is to present the oncologic outcomes and to determine prognostic parameters of overall (OS), cancer specific survival (CSS), disease progression free survival (DPFS) and biochemical progression free survival (BPFS) after surgery for pT3a prostate cancer (PCa). MATERIAL AND METHODS Between 2002 and 2007, a pT3a stage after radical prostatectomy was detected in 126 patients at our institution. Kaplan-Meier analysis was used to calculate OS, CSS, DPFS and BPFS. Cox regression was used to identify predictive factors of survival. RESULTS Five-year OS, CSS, DPFS and BPFS rates were 96%, 98.7%, 97.3% and 60%, respectively. Among patients with prostate specific antigen (PSA) <10 ng/ml and PSA >20 ng/ml the 5-year OS was 98.8% and 80%, respectively, whereas 5-year BPFS was 66% and 16.6%, respectively. Survival was different when comparing surgery Gleason score ≤7 and ≥8. 5-year OS and BPFS were 98% vs. 80%, and 62.6% vs. 27.3%, respectively. Specimen Gleason score and preoperative PSA were significant predictors of BPFS. The risk of biochemical progression increased up to 2-fold when a Gleason score ≥8 was present at final pathology. CONCLUSIONS In locally advanced pT3 PCa, surgery can yield very good cancer control and survival rates especially in cases with PSA <10 ng/ml and Gleason score ≤7. PSA and Gleason score after surgery are the most significant predictors of outcomes after radical prostatectomy.

Abstract
OBJECTIVES To predict bladder outlet obstruction with parameters of non-invasive investigations for patients with symptomatic benign prostatic hyperplasia. PATIENTS AND METHODS A sample of 122 men with moderate to severe lower urinary tract symptoms suggestive of benign prostatic hyperplasia was selected. Transrectal prostate ultrasound, free flow measurement, and transabdominal ultrasound for residual urine were carried out together with digital rectal examination for all patients. All patients underwent urodynamic pressure/flow test. Two groups of obstructed (91 patient) and equivocal/unobstructed (31 patient) were analyzed. Probabilistic model based on logistic regression was developed for prediction of obstruction. RESULTS Various parameters were compared in obstructed and non-obstructed/equivocal groups, highlighting important parameters for obstruction. Correlation analysis indicates higher obstruction dependence on average and peak flow rates and lower dependence on total prostate and transition zone volumes, transition zone index. Binary logistic regression model suggests that average flow rate combined with total prostate volume is the best predictor of obstruction (83% of correct predictions; PPV = 92%; NPV = 52%) in the analyzed sample. The analyzed model suggests that peak flow rate could also be almost equally important parameter instead of average flow rate. CONCLUSIONS The study suggests that average/peak flow rate combined with total prostate volume can be used for prediction of obstruction. The developed probabilistic model helps to determine patients who need invasive urodynamic testing for decision on surgical treatment.

Abstract
Introduction The aim of study was to establish pretreatment and postoperative factors which could predict the early biochemical recurrence after radical prostatectomy. Materials and method 754 patients had undergone radical prostatectomy since January 2002 to December 2008 in our department and were included in this prospective study. Exclusion criteria were: neoadjuvant or adjuvant treatment (radiation or hormonal treatment) and N+. Following parameters were evaluated: age, PSA at time of biopsy, time period from biopsy to operation, biopsy and postoperative Gleason score, stage, high grade intraepithelial neoplasias, perineural invasion. Biochemical recurrence was detected if PSA value after radical prostatectomy was ≥0.2 ng/ml. All factors likely to be predictive were evaluated by univariate analysis (Log-rank test). Multivariate analysis using Cox model was completed for all factors with p value <0.1 at univariate analysis. Results Final analysis was done using data of 496 patients. We detected 53 (10.7%) biochemical recurrences. Calculated actuarial biochemical recurrence free survival reached 64%. Multivariate analysis highlighted that PSA >10 ng/ml (HR 2.45, p = 0.008), pathological stage ≥pT3 (HR 2.371, p = 0.02), postoperative Gleason score ≥7 (HR 2.149, p = 0.049), positive surgical margins (HR 2.482, p = 0.014) and absence of high grade intraepithelial neoplasia in removed prostate (HR 0.358, p = 0.006) are independent factors influencing biochemical recurrence after radical prostatectomy. Conclusion Patients with higher PSA, locally advanced disease, positive surgical margins, and Gleason score ≥7 are at the highest risk for biochemical recurrence.

Abstract
UNLABELLED The objective of the study was to evaluate the relationship between high-grade intraepithelial neoplasia diagnosed after radical retropubic prostatectomy and the clinical and pathological characteristics of prostate cancer, and to evaluate the time to biochemical relapse of the disease within the groups of high-grade prostatic intraepithelial neoplasia (HGPIN) and non-HGPIN patients. MATERIAL AND METHODS Patients, clinically diagnosed with local prostate carcinoma at the Clinic of Urology, Kaunas University of Medicine, during 2003-2007 and treated with radical retropubic prostatectomies, were distributed into two groups according to the HGPIN detected in the postoperative material: HGPIN and non-HGPIN. The two groups were compared in terms of preoperative and postoperative characteristics. The patients who were followed up for at least 12 months were included into the study. The biochemical relapse of prostate cancer was determined if there were two consecutive rises of prostate-specific antigen (PSA) level above 0.2 ng/mL or according to the attending physician's opinion, there was a need for adjuvant treatment even with onetime rise of PSA level above 0.2 ng/mL. RESULTS There was no significant difference between the HGPIN and non-HGPIN groups in terms of time to biochemical relapse and frequency of biochemical relapses, time before surgery, the timing of the HGPIN diagnosis, age, or PSA level. After radical prostatectomy, patients in the HGPIN group were found to have significantly more often poorer cancer cell differentiation according to the Gleason score (≥7 vs. <7; P=0.001) and higher TNM stage (T3a,b vs. T2a,b,c; P=0.001). Fewer positive resection margins were diagnosed in the HGPIN group (P=0.05). The groups did not differ in terms of the degree of differentiation according to the Gleason score or perineural invasion (P=0.811 and P=0.282, respectively). CONCLUSIONS HGPIN was more often associated with the characteristics of the poor prognosis for relapse of prostate cancer: poorer tumor cell differentiation according to the Gleason score and more cases of higher TNM stage. HGPIN did not have any influence on biochemical relapse of the disease during the short-term follow-up.

Abstract
OBJECTIVE. The aim of this prospective study was to establish the influence of operative parameters on outcomes after transurethral resection of the prostate. MATERIALS AND METHODS. In this prospective case series study, 89 patients underwent transurethral resection of the prostate. The standardized protocol was used to investigate the impact of operative parameters (resected tissue weight, residual prostate weight, and residual prostatic weight ratio [total prostate volume - resected tissue weight / total prostate volume]) on outcomes after six months following transurethral resection of the prostate. The evaluation of treatment efficacy was done using the criteria of the Second International Consultation on Benign Prostatic Hyperplasia. All postoperative results were categorized as excellent, good, fair, or none. Treatment was considered effective when the postoperative results were excellent and good, and ineffective when results were fair and none. RESULTS. Treatment was effective for 85.4% and ineffective for 14.6% of the patients. The univariate analysis of operative parameters detected the residual prostatic weight ratio (cutoff value, 0.71; P<0.001; sensitivity, 0.62; specificity, 0.96; OR, 39.47) as the strongest independent predictor of ineffective outcome. Logistic regression analysis revealed two important parameters of unfavorable outcomes: residual prostatic weight ratio (cutoff value, 0.71; P<0.001; OR, 62.16) and residual prostate weight (cutoff value, 26.6 mL; P=0.013; OR, 9.98). When the values of both these parameters were lower than their cutoff values, the probability of an ineffective outcome was reduced to 3%; however, when they were higher, the probability of an unfavorable outcome was increased to 95%. CONCLUSIONS. Residual prostatic weight ratio and residual prostatic weight are significant operative parameters for the prediction of outcomes after transurethral resection of the prostate.

Abstract
BACKGROUND Contraction-excitation feedback, that is, electrophysiologic changes that are caused or preceded by mechanical changes of the myocardium, has been extensively studied in the ventricles. The role of contraction-excitation feedback in the atria, and more particularly in the genesis and maintenance of atrial fibrillation, has been less adequately investigated. HYPOTHESIS The aim of the present study was to determine whether increased right atrial pressure (RAP) facilitates the induction of atrial fibrillation (AF) in patients with a history of lone AF. METHODS Sixteen patients with a history of paroxysmal AF but without structural heart disease were included in the study. All patients underwent electrophysiologic study at both a lower (3.1 +/- 2.0 mmHg) and (in 13 cases) a higher (6.4 +/- 2.5 mmHg) RAP. "Higher" was considered the pressure following rapid (in about 30 min) intravenous administration of normal saline or before the administration of a diuretic. RESULTS Rapid atrial pacing induced AF in 19 of 29 attempts. At a lower pressure, rapid pacing induced brief (3 s to 3 min) AF in 3 of 16 patients, long-lasting (> 3 min) AF in 3 of 16 patients, and no AF in 10 of 16 patients. At a higher pressure, brief AF was induced in 3 of 10 patients in whom no AF could be induced at a lower pressure, and long-lasting AF in 10 patients in whom either brief AF (3 cases) or no AF (7 cases) was induced at a lower pressure. In 11 patients, in whom Wenckebach periodicity was determined at both higher and lower pressure, the critical cycle length at which atrioventricular block appeared was significantly (p < 0.001, paired t-test) longer (349.1 +/- 44.4 ms, i.e., +15.5 +/- 11.3 ms) at higher than at lower atrial pressure (333.6 +/- 41.0 ms). In nine patients, in whom Wenckebach periodicity was determined and two rhythms occurred at different pressures, the critical cycle length was 332.2 +/- 45.8 ms when associated with sinus rhythm, and significantly (p < 0.01) longer (344.4 +/- 48.0 ms, i.e., +12.2 +/- 8.3 ms) when associated with induction of AF. CONCLUSION In patients with lone atrial fibrillation, modest increases in atrial pressure may facilitate the induction of atrial fibrillation.

Abstract
INTRODUCTION Ureteral injuries are uncommon. Upper ureteral defect more than 7-8 cm in length is a challenge for urologists, requiring experience and several steps in its management. We report a case of iatrogenic upper urinary tract injury and successful treatment of 8-cm ureteral defect using autotransplantation of the kidney. CASE REPORT A male patient underwent surgery due to retroperitoneal tumor. Iatrogenic ureteral injury was recognized 18 days after operation. Three-step management of urinary tract injury was performed. The first step included minimally invasive recovery of the urine flow and treatment of infection. The second step was unsuccessful renal descensus and new formation ureteropyeloanastomosis because of difficulties of kidney mobilization caused by previous surgery. The third step included a successful autotransplantation of the kidney and complete reconstruction of the urinary tract. CONCLUSIONS Autotransplantation can be successfully used for the management of long upper ureteral injury in referral urological centers.

Abstract
Major scrotal and penile skin loss is uncommon and management of such an injury is a challenging problem for genitourinary reconstruction surgeons. Less than 50% scrotal skin loss can often be closed without difficulties immediately after trauma with surrounding tissue. In cases of more significant skin loss, the testes may be preserved by placing them in thigh pouches or dressed with wet dressings until reconstruction, or split thickness skin grafting can be performed. The surgeon's decision depends on the cause of skin loss - trauma, Fournier's gangrene or others. We describe a case of massive scrotal and penile skin loss due to an incident with an agricultural machine. The scrotal reconstruction, performed in three steps, was chosen because of its simplicity, early closure of the wound, excellent cosmetic appearance and maintenance of sexual functions. In the first step the penis was covered with remnant scrotal and preputium skin, and the testes were placed in thigh pouches. Incision of thigh flaps was planned to perform the second step and finally scrotal reconstruction with thigh pedicle flaps was done. Results were satisfactory from an esthetical and functional point of view.

Abstract
OBJECTIVE The aim of this study was to estimate the equivalence and correlation between transition zone volume, measured by transrectal ultrasound, and removed prostate tissue weight in surgically treated patients due to benign prostatic hyperplasia. MATERIAL AND METHODS This study involved 168 patients with histologically confirmed benign prostatic hyperplasia. Of these patients, 120 underwent transurethral resection of the prostate and 48 - open prostatectomy. The weights of the specimens were compared with the corresponding volumes of the transition zone. Equivalence and correlation between transition zone volume and removed tissue weight were analyzed. RESULTS The mean (standard deviation, range) transition zone volume was 25.43 mL (+/-13.19, 5-61.6) in the transurethral resection group and 76.1 mL (+/-42.97, 13-275.8) in the open operation group. The mean removed tissue weight was 22.9 g (+/-13.41, 5-66) and 73.96 g (+/-44.96, 18-280), respectively, in the transurethral resection and open operation groups. The correlation between removed tissue weight and transition zone volume was stronger in the open operation group than it was in the resection group (r=0.957, P<0.001 vs. r=0.878, P<0.001). There was a significant difference between transition zone volume and resected tissue weight (P=0.001). However, in the open operation group, there was an agreement between transition zone volume and enucleated tissue weight (P=0.263). CONCLUSIONS A significant correlation was detected between removed tissue weight and transition zone volume. There is a significant difference between volume measurement and resected tissue weight while enucleated tissue weight was in agreement with transition zone volume when an open prostatectomy was performed.

Abstract
UNLABELLED Value of urodynamic pressure-flow studies in evaluation of bladder outlet obstruction has been recognized. Voiding during these studies is influenced by transurethral catheter, which is used for measurement of vesical pressure. We have investigated the influence of 7 F (2.3 mm) catheter on flow rate during pressure-flow study as a potential cause of misclassification. PATIENTS AND METHODS Data of free urinary flow and pressure flow from 111 men with symptomatic benign prostatic hyperplasia were analyzed. Inclusion criteria for analysis: age over 45 years, total International Prostate Symptom Score over 8, maximum flow rate in range of 4-20 ml/s, total voided volume of 100 ml or greater. RESULTS Of all patients, means of maximum free and pressure-flow rate were 9.8 and 9.0 ml/s (p=0.01) with mean voided volume 199 and 212 ml (p=0.03) respectively. Maximum flow rate decreased in 56.8%, increased in 41.4% and was stable in 1.8% of cases. The difference ranged from -8.5 to +10.2 ml/s ('+' is indicated when maximum rate of free flow is higher). In the group of obstructed subjects mean maximum flow rates were respectively 8.8 ml/s and 7.9 ml/s (p=0.01). There was no significant difference in maximum flow rate within the group of unobstructed/equivocal subjects. More pronounced mean 1.3 ml/s difference in maximum flow rate was observed also in subgroup of patients with prostate volumes over 60 cc (p=0.01). CONCLUSIONS Catheter of 7 F (2.3 mm) generally slightly diminishes maximum flow rate. Overdiagnosis of obstruction is more likely if considering the effect of catheter and vesical pressure. Misclassification of subject is possible in case of mild obstruction so such cases should be interpreted with caution. In the case of big difference in maximum flow rate it is necessary to take into account the free flow.

Abstract
OBJECTIVE We compared the efficacy of transurethral resection alone or transurethral resection followed by bladder instillations of Doxorubicin for 1 year in patients with superficial bladder carcinoma, and followed them long term for the incidence of recurrence and progression to muscle invasion. MATERIALS AND METHODS Between December 1998 and December 2000 a total of 69 patients with superficial transitional cell carcinoma of bladder participated in this prospective study. Final analysis of treatment results included 64 patients. Doxorubicin was administered to 25 patients, 39 patients were treated only by TUR. Patients were followed by control cystoscopy. RESULTS The mean follow-up was 22.95 months; SD 7.79. Mean time to first recurrence in Doxorubicin group was 14.14 months; SD 7.84, in TUR alone group - 7.61 months; SD 4.4; p>0.05. Disease free survival was significantly prolonged in Doxorubicin group; p<0.05. There are no significant difference to comparison recurrence rate and progression rate between two groups. CONCLUSIONS In regard to time of first recurrence and disease free survival this study indicates that adjuvant chemotherapy with Doxorubicin is superior to transurethral resection alone. However, progression in stage or recurrence rate was not influenced by the treatment regimen.

Abstract
OBJECTIVES To examine the efficacy of prostate-specific antigen and various parameters obtained by transrectal ultrasonography as predictors of acute urinary retention in patients with benign prostatic hyperplasia. METHODS Eighty-nine men with symptoms of benign prostatic hyperplasia were enrolled in this study from February 2002 to June 2003. Among them, 21 patients presented with acute urinary retention. Transrectal ultrasonography was used to calculate the total prostate volume, transition zone volume and transition zone index. Sample of prostate-specific antigen was taken in outpatient clinic or in clinic before first insertion of the catheter into the bladder, because of urinary retention. If the patient presented with inserted catheter, we used latest prostate-specific antigen date from the medical notes of outpatient clinic. To compare the usefulness of the various indexes, the area under the receiver-operator characteristic curve was calculated for each index. RESULTS There were significant differences between patients with and without acute urinary retention in the total prostate volume (58.16 cm(3) and 44.28 cm(3), p=0.0028), transition zone volume (36.62 cm(3) and 23.70 cm(3), p=0.0001), transition zone index (0.62 and 0.51, p=0.00022), prostate-specific antigen (4.96 ng/ml and 2.97 ng/ml, p=0.00069), age and quality of life score, but no significant difference in International Prostate Symptom Score. In patients with acute urinary retention, the area under the receiver-operator characteristic curve was 0.775 for transition zone index, 0.742 for prostate-specific antigen, 0.737 for transition zone volume, 0.696 for total prostate zone volume and 0.633 for International Prostate Symptom Score. CONCLUSIONS The transition zone index and prostate-specific antigen are accurate predictors of acute urinary retention in patients with benign prostatic hyperplasia and may be useful for deciding between surgical intervention and medical treatment.

Abstract
OBJECTIVE To study whether transrectal ultrasound volume determination of the whole prostate and of the transition zone alone correlates to resected or enucleated weight in patients operated upon with transurethral resection of the prostate and retropubic or suprapubic prostatectomy because of presumed benign prostatic hyperplasia. MATERIAL AND METHODS The study comprised 120 patients with symptomatic benign prostatic hyperplasia. Ninety patients underwent transurethral resection of the prostate and 30 treated using suprapubic or retropubic prostatectomy. The weights of the specimens were correlated with the corresponding volumes of the transition zone and of the whole prostate, respectively, measured by transrectal ultrasound using prolate ellipsoid method. RESULTS The mean weight of the resected or enucleated specimens was 36.79 g. The mean whole prostate volume in all patients was 63.14 cm(3). Difference between resected weight and prostate volume was statistically significant (p= 0.0001), whereas the mean transition zone volume was 40.14 cm(3) and difference with resected weight was not significant (p=0.483). Correlation coefficients between measured total prostate volume and weight of resected tissue as well as between measured transition zone volume and weight of resected tissue were calculated and were respectively r=0.925, p< 0.001 and r=0.958, p<0.001. CONCLUSIONS Measurements of the transition zone of the prostate by transrectal ultrasound are more accurate than those for the whole prostate to predict enucleated or resected weight. The assessment of the transition zone volume may be sufficiently reliable to be used in the clinical management of benign prostatic hyperplasia and helpful to choose modality of the surgery.
