RESUMO

BACKGROUND AND OBJECTIVES: We examined the effect of disease-free interval (DFI) duration on cancer-specific mortality (CSM)-free survival, otherwise known as the effect of conditional survival, in surgically treated adrenocortical carcinoma (ACC) patients. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2018), 867 ACC patients treated with adrenalectomy were identified. Conditional survival estimates at 5-years were assessed based on DFI duration and according to stage at presentation. Separate Cox regression models were fitted at baseline and according to DFI. RESULTS: Overall, 406 (47%), 285 (33%), and 176 (20%) patients were stage I-II, III and IV, respectively. In conditional survival analysis, providing a DFI of 24 months, 5-year CSM-free survival at initial diagnosis increased from 66% to 80% in stage I-II, from 35% to 66% in stage III, and from 14% to 36% in stage IV. In multivariable Cox regression models, stage III (hazard ratio [HR]: 2.38; p < 0.001) and IV (HR: 4.67; p < 0.001) independently predicted higher CSM, relative to stage I-II. The magnitude of this effect decreased over time, providing increasing DFI duration. CONCLUSIONS: In surgically treated ACC, survival probabilities increase with longer DFI duration. This improvement is more pronounced in stage III, followed by stages IV and I-II patients, in that order. Survival estimates accounting for DFI may prove valuable in patients counseling.

RESUMO

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has put a substantial burden on the Italian healthcare system, resulting in the restructuring of hospitals to care for COVID-19 patients. However, this has likely impacted access to care for patients experiencing other conditions. We aimed to quantify the impact of COVID-19 on access to care for patients with urgent/emergent urological conditions throughout Italy. MATERIALS AND METHODS: A questionnaire was sent to 33 urological units in the AGILE consortium, asking clinicians to report on the number of urgent/emergent urological patients seen and/or undergoing surgery over a 3-week period during the peak of the COVID-19 outbreak and a reference week prior to the outbreak. ANOVA and linear regression models were used to quantify these changes. RESULTS: Data from 27 urological centres in Italy showed a decrease from 956 patients/week seen just prior to the outbreak to 291 patients/week seen by the end of the study period. There was a difference in the number of patients with urgent/emergent urological disease seen within/during the different weeks (all p values < 0.05). A significant decrease in the number of patients presenting with haematuria, urinary retention, urinary tract infection, scrotal pain, renal colic, or trauma and urgent/emergent cases that required surgery was reported (all p values < 0.05). CONCLUSION: In Italy, during the COVID-19 outbreak there has been a decrease in patients seeking help for urgent/emergent urological conditions. Restructuring of hospitals and clinics is mandatory to cope with the COVID-19 pandemic; however, the healthcare system should continue to provide adequate levels of care also to patients with other conditions.

RESUMO

AIMS: To assess the long-term complications and outcomes in patients treated for pelvic organ prolapse (POP) with transvaginal anterior colporrhaphy (AC) alone, transvaginal naterior AC with reinforcement by using porcine Xenograft (AC-P) (Pelvisoft® Biomesh), and transvaginal anterior repair with polypropylene mesh (AC-M). METHODS: This was a retrospective analysis of 109/123 consecutive patients, who underwent cystocele repair: 42 AC, 19 AC-P, and 48 AC-M. Subjective outcomes included validated questionnaires as well as questions that had not been previously validated. Objective outcomes have been evaluated considering failure the anterior vaginal wall recurrence >2 stage POP-Quantification. Statistical analysis included the chi-square or Fisher exact test. RESULTS: The mean follow-up was 94.80 ± 51.72 months (19-192 months). In all groups, the patient's personal satisfaction was high. There was no evidence of difference in outcome based on whether a biological graft was or was not performed, or whether synthetic mesh was used to reinforce the repair. Data showed a higher rate of complications in the AC-M group (P < 0.05) that could explain the lower subjective satisfaction of these patients. CONCLUSIONS: This study evaluated long-term outcomes to anterior vaginal repair over a period of more than 5 years in all the groups. Our data show that anterior vaginal repair with mesh and xenograft did not improve significantly objective and subjective outcomes. Rather, prosthetic device use leads to higher rate of complications.

RESUMO

How to manage patients with prostate cancer (PCa) with biochemical recurrence (BCR) following primary curative treatment is a controversial issue. Importantly, this prostate-specific antigen (PSA)-only recurrence is a surrogate neither of PCa-specific survival nor of overall survival. Physicians are therefore challenged with preventing or delaying the onset of clinical progression in those deemed at risk, while avoiding over-treating patients whose disease may never progress beyond PSA-only recurrence. Adjuvant therapy for radical prostatectomy (RP) or local radiotherapy (RT) has a role in certain at-risk patients, although it is not recommended in low-risk PCa owing to the significant side-effects associated with RT and androgen deprivation therapy (ADT). The recommendations for salvage therapy differ depending on whether BCR occurs after RP or primary RT, and in either case, definitive evidence regarding the best strategy is lacking. Options for treatment of BCR after RP are RT at least to the prostatic bed, complete or intermittent ADT, or observation; for BCR after RT, salvage RP, cryotherapy, complete or intermittent ADT, brachytherapy, high-intensity focused ultrasound (HIFU), or observation can be considered. Many patient- and cancer-specific factors need to be taken into account when deciding on the best strategy, and optimal management depends on the involvement of a multidisciplinary team, consultation with the patient themselves, and the adoption of an individualised approach. Improvements in imaging techniques may enable earlier detection of metastases, which will hopefully refine future management decisions.

RESUMO

PURPOSE: The study aimed to evaluate associations of basal levels of total testosterone (TT) with tumor upgrading to high risk disease in low-intermediate risk prostate cancer (PCA). MATERIALS AND METHODS: We retrospectively evaluated the records of 135 patients undergoing radical prostatectomy. Evaluated factors included age, body mass index, prostate specific antigen (PSA), TT, prostate volume, PSA density (PSAD), proportion of biopsy positive cores (P+), clinical tumor stage, and biopsy grading system (1 or 2). Factors associating with tumor upgrading were investigated by the multivariate logistic regression analysis. RESULTS: Tumor upgrading rate to high risk disease was 8.9%. TT, PSA, and PSAD were associated with tumor upgrading. On multivariate analysis, independent factors predicting tumor upgrading were PSA (OR 1.324; p = 0.001) and TT (OR 1.005; p = 0.015). Basal TT was dichotomized up to the third quartile (TT > q3) vs. TT ≤ q3 (426.0 ng/dL). The assessed tumor upgrading risk model showed that TT dichotomized to third quartile (TT > q3 vs. TT ≤ q3) stratified the risk of tumor upgrading (OR 6.577; p = 0.010) along increasing levels of PSA (OR 1.3; p < 0.0001). CONCLUSIONS: Low and intermediate risk PCA patients show a not negligible risk of tumor upgrading to high risk disease. In this particular subset of patients, basal levels of TT stratify the risk of tumor upgrading.

RESUMO

PURPOSE: The study aimed to investigate clinical factors associating with occult lymph node micrometastases (pN1 disease) in a contemporary cohort of organ-confined prostate cancer (PCA) patients staged as cN0. MATERIALS AND METHODS: The study evaluated 184 consecutive patients. Associations of clinical factors with pN1 disease were assessed by multivariate logistic regression analysis. RESULTS: Lymph node invasion was detected in 33 cases (17.9%). Independent factors associating with pN1 status were prostate specific antigen (PSA; OR 1.054; p = 0.004), percentage of positive biopsy cores (PPC; OR 1.030; p = 0.013), and biopsy Gleason pattern (bGP) >4 + 3 (OR 3.666; p = 0.004). A clinical model predicting the risk of pN1 disease identified 4 prognostic groups of pN1 disease. CONCLUSIONS: In a contemporary cohort of PCA patients, lymph node invasion was detected in 17.9% of cases. An independent clinical disease showed that the risk of lymph node invasion was directly proportional to PPC and more stratification of the risk of pN1 disease was operated by PSA and BGP. The model allowed the stratification of the patient population in 4 groups and showed that the risk of lymph node invasion progressively increased as the risk group ranked from 1 to 4.

RESUMO

OBJECTIVES: To evaluate clinical factors associated with tumour upgrading (UPG) in low-intermediate risk patients who progressed while under active surveillance (AS) and underwent delayed radical prostatectomy. MATERIAL AND METHODS: The evaluated factors included prostate specific antigen (PSA), prostate volume, PSA density and number of biopsy positive cores (BPC). Multivariate logistic regression by the forward step Wald procedure was used. RESULTS: The study evaluated 24 patients who had UPG in 13 cases (54.2%). Independent factors associated with tumour UPG included PSA (OR 2.1; p = 0.047) and BPC (OR 2; p = 0.042). CONCLUSIONS: Clinical factors associated with UPG were identified in patients who were under AS for with low-intermediate risk disease. Preoperative PSA levels and number of BPC were independent factors associated with UPG in a contemporary cohort of patients who progressed under AS and underwent delayed active treatment.

RESUMO

OBJECTIVES: To evaluate clinical predictors of disease reclassification or progression (DR/P) in prostate cancer patients elected to active surveillance (AS). MATERIAL AND METHODS: Patients were assessed on the basis of DR/P criteria. Predictors of DR/P were evaluated by multivariate logistic regression and Cox proportional hazards. RESULTS: The median DR/P free time was 16.5 months. DR/P was detected in 30 out of 84 cases (35.7%). In DR/P cases, the median prostate volume (PV) was significantly lower (34.7 vs. 42.7 ml) and the percentage of cases with 2 or 3 vs. 1 initial biopsy positive cores (BPC) was significantly higher (36.7 vs. 7.4%). The multivariate logistic regression model showed that PV (OR 0.9; p = 0.021) and initial n >1 BPC (OR 9.8; p = 0.001) were independent predictors of DR/P. By Cox multivariate proportional hazards, only n >1 BPC predicted early DR/P (hazard ratio 3.1; p = 0.003). CONCLUSIONS: In a contemporary cohort of patients elected to AS, independent factors stratifying the risk of DR/P were PV and initial BPC, which also predicted early DR/P. In patients elected to AS, the identification of risk factors of DR/P require early re-biopsy. Confirmatory studies are required.

RESUMO

BACKGROUND: Benign prostatic hyperplasia and prostate cancer (PCA) alter the normal growth patterns of zonal anatomy with changes of prostate volume (PV). Chronic inflammatory infiltrates (CII) type IV are the most common non-cancer diagnosis of the prostate after biopsy. OBJECTIVE: To evaluate associations of both PV index (PVI), i.e. the ratio of transitional zone volume (TZV) to peripheral zone volume (PZV), and CII with PCA in patients undergoing biopsy. SUBJECTS AND METHODS: Between January 2007 and December 2008, 268 consecutive patients who underwent prostate biopsy were retrospectively evaluated. PV and TZV were measured by transrectal ultrasound. PZV was computed by subtracting the PV from the TZV. CII were evaluated according to standard criteria. Significant associations of PVI and the presence of CII (CII+) with PCA risk were assessed by statistical methods. RESULTS AND LIMITATIONS: We evaluated 251 patients after excluding cases with painful rectal examinations, prostate-specific antigen (PSA) >20 µg/ml and metastases. The PCA detection rate was 41.1%. PVI was a negative independent predictor of PCA. A PVI ≤1.0 was directly [odds ratio (OR) = 2.36] associated with PCA, which was detected more frequently in patients with a PVI ≤1.0 (29.1%) than in those with a PVI >1.0 (11.9%). CII+ was inversely (OR = 0.57) and independently associated with PCA, which was detected less frequently in cases with CII (9.9%) than in those without CII (21.1%). Potential study limitations might relate to the fact that PV was not measured by prostatectomy specimens and there was PSA confounding for CII and PCA. CONCLUSIONS: Low values of PVI are directly associated with risk of PCA, which was almost 2.5 times higher in patients with a PVI ≤1.0. The PVI might be an effective parameter for clustering patients at risk of PCA. CII+ was inversely associated with risk of PCA and decreased the probability of detecting PCA by 43%. The role of the PVI and CII in PCA carcinogenesis needs further research.

RESUMO

PURPOSE OF REVIEW: Female dysfunctional voiding (FDV) is an intermittent and/or fluctuating flow rate due to involuntary intermittent contractions of the periurethral striated or levator muscles during voiding in neurologically normal women. Despite its codified definition, because of variable causes, there is a lack of established diagnostic criteria and management. The aim of this study is to give a comprehensive, brief review of the most recent progress in the diagnosis and management of FDV. RECENT FINDINGS: Currently, there is the need to shed light on several issues in FDV, such as the use of standardized definitions, diagnostic criteria, and treatment modalities. The evaluation of the progress on these matters within 2013 helped to define some key advances in the field of female functional voiding dysfunction and urinary retention. SUMMARY: In 2013, many diagnostic and therapeutic questions in female voiding dysfunction remain unsolved. However, some data began to emerge. Patients with FDV did not demonstrate a difference in effortful control (effortful control is the ability to regulate one's responses to external stimuli), but did demonstrate a higher rate of surgency (surgency is a trait aspect of emotional reactivity in which a person tends towards high levels of positive affect). Toilet training method in childhood does not seem to have any long-term correlation with FDV. Training with pelvic floor physiotherapy and biofeedback still represents the first-line treatment for FDV. In the management of other causes of female voiding dysfunction, sacral neuromodulation demonstrated a satisfying long-term efficacy in the treatment of nonobstructive urinary retention.

RESUMO

BACKGROUND: The debate between single-layer and double-layer renorrhaphy techniques during robot-assisted partial nephrectomy (RPN) represents a subject of ongoing discourse. The present analysis aims to compare the perioperative and functional outcomes of single- versus double-layer renorrhaphy during RPN. METHODS: Study data were retrieved from prospectively maintained institutional database (Jan2018-May2023). Study population was divided into two groups according to the number of layers (single vs. double) used for renorrhaphy. Baseline and perioperative data were compared. Postoperative surgical outcomes included type and grade of complications as classified according to Clavien-Dindo. Serum creatinine and estimated glomerular filtration rate were used to measure renal function. RESULTS: Three hundred seventeen patients were included in the analysis: 209 received single-layer closure, while 108 underwent double-layer renorrhaphy. Baseline characteristics were not statistically different between the groups. Comparable low incidence of intraoperative complications was observed between the cohorts (P=0.5). No difference was found in terms of mean (95% CI) Hb level drop postoperation (single-layer: 1.6 g/dL [1.5-1.7] vs. double-layer: 1.4 g/dL [1.2-1.5], P=0.3). Overall and "major" rate of complications were 16% and 3%, respectively, with no difference observed in terms of any grade (P=0.2) and major complications (P=0.7). Postoperative renal function was not statistically different between the treatment modalities. At logistic regression analyses, no difference in terms of probability of overall (OR 0.82 [0.63-1.88]) and major (OR 0.94 [0.77-6.44]) complications for the number of suture layers was observed. CONCLUSIONS: Single-layer and double-layer renorrhaphy demonstrated comparable perioperative and functional outcomes within the setting of the present study.

RESUMO

BACKGROUND: The aim is to evaluate factors impacting operating time (OT) during robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND) for prostate cancer. METHODS: Overall, 1289 patients underwent RARP from January 2013 to December 2021. ePLND was performed in 825 cases. Factors potentially associated with OT variations were assessed. Three low-volume (LVS) and two high-volume surgeons (HVS) performed the procedures. A linear regression model was computed to assess associations with OT variations. RESULTS: When RARP was performed by HVS an OT decrease was observed independently by significant clinical (Body Mass Index [BMI]; prostate volume [PV]) and anatomical/perioperative features (prostate weight [PW]; intraoperative blood loss [BL]) both in clinical (change in OT: -42.979 minutes; 95% CI: -51.789; -34.169; P<0.0001) and anatomical/perioperative models (change in OT: -40.020 minutes; 95% CI: -48.494; -31.587; P<0.0001). A decreased OT was observed in clinical (change in OT: -27.656 minutes; 95% CI: -33.449; -21.864; P<0.0001) and anatomical/perioperative (change in OT: -24.935 minutes; 95% CI: -30.562; -19.308; P<0.0001) models also in case of RARP with ePLND performed by HVS, independently by BMI, PV, PSA as well as for PW, seminal vesicle invasion, positive surgical margins, and BL. CONCLUSIONS: In a tertiary academic referral center, OT decreased when RARP was performed by HVS, independently of adverse clinical and anatomical/perioperative factors. Available OT loads can be planned to optimize waiting lists, teaching tasks, operative costs, and surgeon's volume.

RESUMO

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

RESUMO

BACKGROUND: Routine processing of prostate biopsies requires conventional steps that usually take a few days. The aim of this study was to validate the use of fluorescence laser confocal microscopy (FCM) for real-time diagnostics. METHODS: We prospectively tested images from prostate needle biopsies (75 images were evaluated by FCM and conventional slides). Two pathologists reviewed the images and assessed agreements between FCM versus conventional slides and between pathologists (κ-values). Interpretation was performed on digital images from the VivaScope 2500 confocal microscope (MAVIG GmbH, Munich, Germany; Caliber I.D., Rochester, NY, USA) placed in the urological operating room. Cancerous versus benign tissue was the primary focus, then the application of the grading system. RESULTS: Cancer was diagnosed in 24 conventional slides (on 75 images) in which agreement among pathologists was high for both conventional (κ=0.96) and FMC (κ=0.84). 1/24 (4%) was ISUP/WHO grade group I, 12/24 (50%) II, 8/24 (33%) III, 2/24 (8%) IV and 1/24 (4%) grade V. Near perfect agreement was obtained for grades I, IV and V (κ=0.85). Grade III values achieved a moderate agreement (κ=0.55). The mean time for laser scanning was 9 minutes. For the remaining non-tumor images, agreement was nearly perfect (κ=0.81). CONCLUSIONS: We validated the use of FCM for real-time cancer detection in prostate biopsies.

RESUMO

BACKGROUND: We tested for regional differences across United States (US) in rates of adrenalectomy, systemic therapy, and adrenalectomy and systemic therapy combination for adrenocortical carcinoma (ACC) patients. We hypothesized that no differences exist, especially after accounting for baseline patient and tumor characteristics. METHODS: Within Surveillance, Epidemiology, and End Results (SEER) database (2004-2018), 1275 ACC patients were identified. Distribution of patient age, tumor size, ENSAT (European Network for the Study of Adrenal Tumors) stages, and treatments were tabulated and graphically displayed, according to nine geographical registries, corresponding to the population of specific states, cities or macro areas of the US on which the data are based on. Multinomial models predicted treatment probability for each patient according to registries. RESULTS: Patients count according to registries ranged from 62 to 509. Differences across registries existed for age (range 54-59 years; P=0.4), tumor size (8.5-11.0 cm; P=0.2), ENSAT stage (1-11% vs. 17-35% vs. 18-32% vs. 24-44%, in respectively ENSAT stage I, II, III, and IV), and treatment distribution (35-53% vs. 5-21% vs. 23-42%, in respectively adrenalectomy, systemic therapy, and adrenalectomy and systemic therapy combination; P=0.039). After adjustment for age, stage and year of diagnosis, clinically meaningful residual differences across registries remained for adrenalectomy (33-54%), systemic therapy (4-19%), and adrenalectomy and systemic therapy combination (20-38%). However, most variability originated from registries with smallest sample sizes. CONCLUSIONS: We identified important variability in ACC treatment according to SEER geographical registries, even after considering baseline patient and tumor characteristics. These findings may be indicative of differences in quality of care or expertise in ACC management.

RESUMO

BACKGROUND: Since before the COVID-19 pandemic, hospital-acquired infections (HAIs) represented a global healthcare crisis. Few studies suggested that COVID-19-related basic hygiene measures (BHM) could lower HAIs rates, reaching inconclusive results. The aim of this study was to investigate the hypothetical benefit on HAIs rate of COVID-19-enhanced BHM systematic introduction after major elective urological surgery. METHODS: Since the pandemic began, our hospital has implemented BHM to limit the spread of COVID-19. We compared patients operated in the pre-COVID-19 era (no-BHM period) with those operated after the pandemic started (BHM period). Outcomes were the incidence of HAIs and postoperative complications, and the length of hospital stay (LOS). Two balanced groups were generated by propensity score 1:1 matching. RESULTS: Of 1053 major urological interventions, 604 were performed in the no-BHM period, and 449 in the BHM period. After matched analysis, the comparison groups consisted of 310 patients each. Of 107 recorded HAIs, 43 occurred during the BHM period (13.9%), and 64 during the no-BHM period (20.7%), with a statistically significant difference in multivariable analysis (OR 0.5 [95% CI 0.3-0.8], P=0.004). Postoperative complications rate was significantly lower in the BHM period than in the no-BHM period (29.0% versus 36.5%, OR 0.6 [95% CI 0.4-0.9], P=0.01). The LOS differed significantly between BHM and no-BHM periods: a median of 5 (5-8) days versus 6 (5-8), respectively (P<0.001). CONCLUSIONS: The risk of infections, postoperative complications, and prolonged LOS after major urological surgery was significantly reduced with the systematic introduction of COVID-19-related BHM, their application could, therefore, be prolonged with lasting benefits.

RESUMO

BACKGROUND: Utility of partial nephrectomy (PN) for complex renal mass (CRM) is controversial. We determined the impact of surgical modality on postoperative renal functional outcomes for CRM. METHODS: We retrospectively analyzed a multicenter registry (ROSULA). CRM was defined as RENAL Score 10-12. The cohort was divided into PN and radical nephrectomy (RN) for analyses. Primary outcome was development of de-novo estimated glomerular filtration rate (eGFR)<45 mL/min/1.73 m2. Secondary outcomes were de-novo eGFR<60 and ΔeGFR between diagnosis and last follow-up. Cox proportional hazards was used to elucidate predictors for de-novo eGFR<60 and <45. Linear regression was utilized to analyze ΔeGFR. Kaplan-Meier Analysis (KMA) was performed to analyze 5-year freedom from de-novo eGFR<60 and <45. RESULTS: We analyzed 969 patients (RN=429/PN=540; median follow-up 24.0 months). RN patients had lower BMI (P<0.001) and larger tumor size (P<0.001). Overall postoperative complication rate was higher for PN (P<0.001), but there was no difference in major complications (Clavien III-IV; P=0.702). MVA demonstrated age (HR=1.05, P<0.001), tumor-size (HR=1.05, P=0.046), RN (HR=2.57, P<0.001), and BMI (HR=1.04, P=0.001) to be associated with risk for de-novo eGFR<60 mL/min/1.73 m2. Age (HR=1.03, P<0.001), BMI (HR=1.06, P<0.001), baseline eGFR (HR=0.99, P=0.002), tumor size (HR=1.07, P=0.007) and RN (HR=2.39, P<0.001) were risk factors for de-novo eGFR<45 mL/min/1.73 m2. RN (B=-10.89, P<0.001) was associated with greater ΔeGFR. KMA revealed worse 5-year freedom from de-novo eGFR<60 (71% vs. 33%, P<0.001) and de-novo eGFR<45 (79% vs. 65%, P<0.001) for RN. CONCLUSIONS: PN provides functional benefit in selected patients with CRM without significant increase in major complications compared to RN, and should be considered when technically feasible.

RESUMO

BACKGROUND: The investigate the associations of the ASA physical status system with clinical, pathological, and perioperative features of prostate cancer (PCa) patients treated with radical prostatectomy (RP) that eventually associated with pelvic lymph node dissection (PLND). METHODS: We performed a retrospective analysis of prospective collected data from January 2013 to October 2020, including1329 patients. The ASA system was preoperatively assessed for each patient. Evaluated clinical factors were grouped as preoperative, perioperative, and pathological and were statistically associated with the ASA system. Continuous variables were represented as medians with relative interquartile ranges (IQR) and categorical factors were assessed as frequencies (percentages). Associations and risk of each ASA Class with population features were assessed by the multinomial logistic regression model (univariate and multivariate analysis). All tests were two-sided with P<0.05 considered to indicate statistical significance. RESULTS: Postoperative complications at discharge occurred in 27.2%. The distribution of the ASA physical status system was as follows: ASA I 108 patients (8.1%), ASA II 1081 subjects (81.3%) and ASA III 140 cases (10.5%). Median length of hospital state (LOHS) was the same for ASA groups I and II (4 days), but longer (5 days) for the ASA group III. On MVA, the risk of delayed hospital stay was associated only with ASA III patients and was independent from age and BMI. Clavien-Dindo complications greater than 2 did not show any independent association with the ASA system. CONCLUSIONS: The ASA preoperative physical status system predicted the likelihood of longer LOHS.

RESUMO

BACKGROUND: Radical nephroureterectomy (RNU) with the concomitant excision of the distal ureter and bladder cuff is the current standard of care for the treatment of muscle invasive and/or high-risk upper tract urothelial carcinoma (UTUC). In small uncontrolled studies, laparoscopic RNU has been suggested to be associated with better perioperative outcomes compared to open RNU. The aim of our study was to compare the perioperative oncological and functional outcomes of open RNU versus laparoscopic RNU after adjusting for preoperative baseline patient-related characteristics. METHODS: We evaluated a multi-institutional retrospective database composed by 1512 patients diagnosed with UTUC and treated with open or laparoscopic RNU between 1990 and 2016. Perioperative outcomes included operative time, blood loss, and length of hospital stay, as well as postoperative complications, readmission, reoperation, and mortality rates at 30 and 90 days from surgery. A 1:1 propensity score matching estimated using logistic regression with the teffects psmatch function of STATA 13® (caliper 0.2, no replacement; StataCorp LLC; College Station, TX, USA) was performed using preoperative parameters such as: age, gender, Body Mass Index (BMI), and American Society of Anesthesiologists (ASA) Score. RESULTS: Overall, 1007 (66.6%) patients were treated with open and 505 (33.4%) with laparoscopic RNU. Open RNU resulted into shorter median operative time (180 vs. 230 min, P<0.001) and longer median hospital stay (10 vs. 7 days, P<0.001) in comparison to laparoscopic RNU. No statistically significant difference was identified for the other variables of interest (all P>0.05). At multivariable linear regression after propensity score matching adjusted for lymph node dissection and year of surgery, laparoscopic RNU resulted in longer operative time (coefficient 43.6, 95% CI 27.9-59.3, P<0.001) and shorter hospital stay (coefficient -1.27, 95% CI -2.1 to -0.3, P=0.01) compared to open RNU, but the risk of other perioperative complications remained similar between the two treatments. CONCLUSIONS: Laparoscopic RNU is associated with shorter hospital stay, but longer operative time in comparison to open RNU. Otherwise, there were no differences in other perioperative outcomes between these surgical modalities even after propensity score matching. The choice to offer laparoscopic or open RNU in the treatment of UTUC should not be based on concerns of different safety outcomes.

RESUMO

PURPOSE OF REVIEW: To review the reported effectiveness and safety of transobturator (TransOburator route, TOR) versus retropubic (retropubic tape) synthetic mid-urethral slings discussing the controversy existing on which of these procedures is best. RECENT FINDINGS: From August 2009 to January 2011 three meta-analyses of the pertinent topic were identified. They concluded that TOR was less favourable than the retropubic tape in objective cure rates without any significant difference in subjective cure rates. Moreover TOR showed a shorter operating time and less serious perioperative complications than retropubic tape, also when using a standardized complications grading system. The most recent RCTs confirmed these results. SUMMARY: TOR showed similar short and mid-term subjective cure rates compared to retropubic tape; with a shorter operating time and a lower risk of perioperative complications. Subjective cure rates and patient satisfaction are crucial, thus, patient-report outcomes should be used as the primary outcome measure for all trials of incontinence treatments. The absence of standard methods for assessment of anti-incontinence procedures and the use of different methods to evaluate safety and effectiveness led to reporting of different rates of success and complications for the same procedure, making it difficult to compare data, to draw conclusions or make recommendations.
