Surgical and Oncological Outcomes of Level III-IV Versus Level I-II Inferior Vena Cava Thrombectomy: A Decennial Experience of a High-Volume European Referral Center.

BACKGROUND: In patients with renal cell carcinoma (RCC) the role of the extent of tumor thrombus into the inferior vena cava (IVC) has never been addressed from a surgical and oncologic standpoint. This study aims to evaluate differences between level III-IV versus level I-II patients concerning peri- and postoperative morbidity, additional treatments and long-term oncological outcomes. PATIENTS AND METHODS: Overall, 40 patients with RCC underwent radical nephrectomy (RN) with IVC thrombectomy at a single European institution between 2010 and 2023. Complications were reported according to the European Union (EAU) guidelines recommendations. Spider chart served as graphical depiction of surgical and oncologic outcomes. RESULTS: Overall, 22 (55%) and 18 (45%) patients harbored level III-IV and I-II IVC thrombus. Level III-IV patients experienced significantly higher rates of intraoperative transfusions (68 vs 39%), but not significantly higher rates of intraoperative complications (32% vs 28%). Level III-IV patients had significantly higher rates of postoperative transfusions (82% vs 33%) and Clavien Dindo ≥3 complications (41% vs 15%). In level III-IV versus level I-II patients, median follow up was 482 and 1070 days, the rate of distant recurrence was 59% and 50%, the rate of systemic progression was 27% and 13%, and the rate of additional treatment/s was 64% and 61%, respectively (all p values > 0.05). Overall survival was 36% in level III-IV patients and 67% in level I-II (p = 0.001). CONCLUSIONS: Our findings suggest that patients with level III-IV RCC who are candidates for IVC thrombectomy should be counselled about the higher likelihood of postoperative severe adverse events and worse overall survival relative to level I-II counterparts.

Challenging cases in high-risk prostate cancer patients treated with Retzius-sparing robot-assisted radical prostatectomy.

OBJECTIVE: To evaluate the relationship between enlarged prostate, bulky median lobe (BML) or prior benign prostatic hyperplasia (BPH) surgery and perioperative functional, and oncological outcomes in high-risk (HR) prostate cancer (PCa) patients treated with Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). METHODS: 320 HR-PCa patients treated with RS-RARP between 2011 and 2020 at a single high-volume center. The relationship between prostate volume, BML, prior BPH surgery and perioperative outcomes, Clavien-Dindo (CD) grade ≥ 2 90-day postoperative complications, positive surgical margins (PSMs), and urinary continence (UC) recovery was evaluated respectively in multivariable linear, logistic and Cox regression models. Complications were collected according to the standardized methodology proposed by EAU guidelines. UC recovery was defined as the use of zero or one safety pad. RESULTS: Overall, 5.9% and 5.6% had respectively a BML or prior BPH surgery. Median PV was 45 g (range: 14-300). The rate of focal and non-focal PSMs was 8.4% and 17.8%. 53% and 10.9% patients had immediate UC recovery and CD ≥ 2. The 1- and 2-yr UC recovery was 84 and 85%. PV (p = 0.03) and prior BPH surgery (p = 0.02) was associated with longer operative time. BML was independent predictor of time to bladder catheter removal (p = 0.001). PV was independent predictor of PSMs (OR: 1.02; p = 0.009). Prior BPH surgery was associated with lower UC recovery (HR: 0.5; p = 0.03). CONCLUSION: HR-PCa patients with enlarged prostate have higher risk of PSMs, while patients with prior BPH surgery have suboptimal UC recovery. These findings should help physicians for accurate preoperative counseling and to improve surgical planning in case of HR-PCa patients with challenging features.

Uro-oncologic patient management during the COVID-19 pandemic: survey findings from an Italian oncologic hub.

Aim: Patient and worker satisfaction at an oncologic hub during the COVID-19 pandemic has never been reported. We addressed this topic. Methods: We conducted a survey to test the views of patients (n = 64) and healthcare professionals (n = 52) involved with our operative protocol. Results: A moderate/severe grade of concern due to the COVID-19 emergency was recorded in 63% of patients versus 75% of hospital staff. High/very high versus low satisfaction grade about preventive strategies to reduce the risk of SARS-CoV-2 contagion was identified in the patients compared with the hospital staff group. Conclusion: Surgical treatment at a hub center of uro-oncologic patients coming from spoke centers is well accepted and should, therefore, be recommended. Preventive strategies to reduce the risk of SARS-CoV-2 contagion in hospital staff members should be implemented.

Lay abstract We provide robust evidence that an oncologic hub center during COVID-19 pandemic represents a credible solution for management of non-deferrable uro-oncologic patients. Specifically, surgical treatment at a hub center of patients coming from spoke centers is well accepted by both patients and hospital staff members. Moreover, collaboration between healthcare workers from spoke and hub centers generates minimal levels of anxiety, while potentially being associated with clinical, surgical and scientific improvement. This said, a more specific focus on recommended strategies to reduce the risk of SARS-CoV-2 contagion at oncologic hub hospitals is warranted.

Proficiency score as a predictor of early trifecta achievement during the learning curve of robot-assisted radical prostatectomy for high-risk prostate cancer: Results of a multicentric series.

Background: Recently, an innovative tool called "proficiency score" was introduced to assess the learning curve for robot-assisted radical prostatectomy (RARP). However, the initial study only focused on patients with low-risk prostate cancer for whom pelvic lymph node dissection (PLND) was not required. To address this issue, we aimed to validate proficiency scores of a contemporary multicenter cohort of patients with high-risk prostate cancer treated with RARP plus extended PLND by trainee surgeons. Material and methods: Between 2010 and 2020, 4 Italian institutional prostate-cancer datasets were merged and queried for "RARP" and "high-risk prostate cancer." High-risk prostate cancer was defined according to the most recent European Association of Urology guidelines as follows: prostate-specific antigen >20 ng/mL, International Society of Urological Pathology ≥4, and/or clinical stage (cT) ≥ 2c on preoperative imaging. The selected cohort (n = 144) included clinical cases performed by trainee surgeons (n = 4) after completing their RARP learning curve (50 procedures for low-risk prostate cancer). The outcome of interest, the proficiency score, was defined as the coexistence of all the following criteria: a comparable operation time to the interquartile range of the mentor surgeon at each center, absence of any significant perioperative complications Clavien-Dindo Grade 3-5, no perioperative blood transfusions, and negative surgical margins. A logistic binary regression model was built to identify the predictors of 1-year trifecta achievement in the trainee cohort. For all statistical analyses, a 2-sided p < 0.05 was considered significant. Results: A proficiency score was achieved in 42.3% patients. At univariable level, proficiency score was associated with 1-year trifecta achievement (odds ratio, 8.77; 95% confidence interval, 2.42-31.7; p = 0.001). After multivariable adjustments for age, nerve-sparing, and surgical technique, the proficiency score independently predicted 1-year trifecta achievement (odds ratio, 9.58; 95% confidence interval, 1.83-50.1; p = 0.007). Conclusions: Our findings support the use of proficiency scores in patients and require extended PLND in addition to RARP.

Retzius-sparing Robot-assisted Radical Prostatectomy in High-risk Prostate Cancer Patients: Results from a Large Single-institution Series.

Background: Retzius-sparing (RS) robot-assisted radical prostatectomy represents a valid surgical treatment option for prostate cancer (PCa) patients. However, the available evidence on the role of RS in high-risk (HR) PCa setting is sparse. Objective: To describe our RS technique for HR-PCa patients and to evaluate intra-, peri-, and postoperative oncological and functional outcomes. Design setting and participants: A total of 340 D'Amico HR-PCa patients underwent RS at a single high-volume centre between 2011 and 2020. Surgical procedure: Surgical procedures were performed by five experienced robotic surgeons. Measurements: Complications were collected according to the standardised methodology proposed by the European Association of Urology guidelines. Postoperative outcomes were evaluated in patients with complete follow-up data (n = 320). Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values of ≥0.2 ng/ml. Urinary continence (UC) recovery was defined as the use of zero or one safety pad. Kaplan-Meier and multivariable logistic and Cox regression models were performed. Results and limitations: Fourteen patients (4%) experienced intraoperative complications and 52 90-d complications occurred in 44 patients (14%), of whom 24 had Clavien-Dindo 3a/b. Final pathology reported 49% International Society of Urological Pathology (ISUP) grade 4-5, 55% ≥pT3a, and 28.8% positive surgical margins (PSMs; 9.4% focal and 19.4% extended PSMs). The median follow-up was 47 mo. Overall, 35.3% and 1.3% harboured BCR and died from PCa. At 4 yr of follow-up, BCR-free survival and additional treatment-free survival were 63.6% and 56.6%, respectively. ISUP 4-5 at biopsy (odds ratio [OR]: 2.6), prostate volume (OR: 1.03), partial or full nerve sparing (OR: 1.9), and full bladder neck preservation (OR: 2.2) were independent predictors of PSMs. Pathological ISUP 4-5 (hazard ratio [HR]: 1.5) and PSMs (HR: 2.3) were independent predictors of BCR. Pathological ISUP 4-5 (HR: 1.5), PSMs (HR: 2.4), pT ≥3b (HR: 1.8), and pN ≥1 (HR: 1.8) were independent predictors of additional treatment. Immediate UC recovery was recorded in 53% patients. The 1- and 2-yr UC recovery and erectile function recovery were, respectively, 84% and 85%, and 43% and 50%. Conclusions: RS in HR-PCa patients allows optimal intra-, peri-, and postoperative outcomes. The RS approach should be considered a valid surgical treatment option for HR-PCa patients in expert hands. Patient summary: Relying on the largest cohort of high-risk prostate cancer patients treated with Retzius sparing (RS), we observed that the RS approach is safe and allows optimal cancer control, without significantly compromising functional outcomes.

The extent of tumour fat invasion affects survival in patients with renal cell carcinoma and venous tumour thrombosis.

OBJECTIVE: • To investigate the effect of presence and extent of tumour fat invasion (TFI) - perinephric invasion (PFI), renal sinus fat invasion (RSFI) or both PFI and RSFI - on cancer-specific mortality (CSM) in patients with renal cell carcinoma (RCC) and venous tumour thrombus (VTT). METHODS: • We examined 184 consecutive patients with RCC with VTT treated with nephrectomy between 1987 and 2007. Associations with CSM were evaluated by univariable and multivariable Cox proportional hazard models. RESULTS: • Median follow up was 21 months. The 5-year CSM-free survival estimates were 75%, 36% and 20% in patients with VTT without TFI, those with VTT with PFI or RSFI, and those with VTT with both PFI and RSFI, respectively (P < 0.001). In multivariable analyses, presence of either PFI or RSFI was associated with a two-fold increased risk of CSM, whereas presence of both PFI and RSFI was associated with a three-fold increased risk of CSM, relative to VTT-only cases. • The inclusion of the variable describing the presence and extent of TFI in a base model including pT stage, Fuhrman grade and presence of nodal disease and metastatic disease significantly increased the accuracy in predicting CSM (+2.1%; P < 0.001) in patients with VTT. CONCLUSIONS: • Patients affected by RCC with VTT and TFI have a higher risk of CSM relative to cases with VTT only. Patients with both PFI and RSFI showed increased CSM compared with patients with either PFI or RSFI. • Our results suggest TFI should be accurately evaluated and included in routine pathological reports to provide better patient risk stratification.

Retzius-sparing Robotic Radical Prostatectomy for Surgeons in the Learning Curve: A Propensity Score-matching Analysis.

BACKGROUND: Several authors claimed that the Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) needs a prolonged learning curve, and outcomes during this phase could be suboptimal. OBJECTIVE: To verify the safety and outcomes of RS-RARP performed by young surgeons during the learning curve. DESIGN, SETTING, AND PARTICIPANTS: We conducted a retrospective analysis of the pre-, intra-, and postoperative features of all the patients who underwent RS-RARP from 2013 to 2017. We divided our patients into two groups: patients operated by two experienced surgeons (ESs) with >100 procedures and patients operated on by five younger surgeons in the learning curve (LCSs). LCSs had no previous experience in radical prostatectomy, and the very first RS-RARP procedures of each LCS case are included in the analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Perioperative, oncological, and functional data were analyzed. Short-term oncological results were reported as positive surgical margins (PSMs) and 1-yr disease-free survival. Complications were graded according to the Clavien-Dindo system. Potency was defined as erections sufficient for intercourse; continence was defined as no pad or one safety liner. A propensity score-matching analysis was used to adjust the difference in baseline preoperative parameters between the groups. RESULTS AND LIMITATIONS: We obtained two homogeneous groups of 256 patients each. After the matching, preoperative variables were similar in the two groups. The mean console time was longer for younger surgeons (98 vs 122 min, p < 0.001). Postoperative course, complications, and functional results were similar in the two groups; the final pathological analysis showed a worse T stage in the ES group (p = 0.017). PSMs and 1-yr disease-free survival did not differ between the groups. CONCLUSIONS: RS-RARP can be safely performed by inexperienced surgeons who have received adequate training. PATIENT SUMMARY: Surgeons in the learning curve can perform Retzius-sparing robot-assisted radical prostatectomy safely, with similar early oncological results and functional outcomes.

Overview of the italian experience in surgical management of bladder cancer during first month of COVID-19 pandemic.

OBJECTIVE: Overview of bladder cancer (BC) management in Italy during the first month of the COVID-19 pandemic (March 2020) with head to head comparison of the data from March 2019, considered "usual activity" period. The aim is to analyze performance of different Italian Centers in North, Center and South, with a special eye for Lombardy (the Italian epicenter). PATIENTS AND METHODS: During April 2020, a survey containing 14 multiple-choice questions focused on general staffing and surgical activity related to BC during the months of March 2019 and March 2020 was sent to 32 Italian Centers. Statistical analysis was performed using IBM SPSS Statistics (v26) software. A Medline search was performed, in order to attempt a comparative analysis with published papers. RESULTS: 28 Centers answered, for a response rate of 87.5%. Most of the urology staff in the Lombardy region were employed in COVID wards (p = 0.003), with a statistically significant reduction in the number of radical cystectomies (RC) performed during that time (p = 0.036). The total amount of RC across Italy remained the same between 2019 and 2020, however there was an increase in the number of surgeries performed in the Southern region. This was most likely due to travel restrictions limiting travel the North. The number of Trans-Urethral Resection of Bladder Tumors (TURBT) (p = 0.046) was higher in Academic Centers (AC) in 2020 (p = 0.037). CONCLUSIONS: The data of our survey, although limited, represents a snap shot of the management of BC during the first month of the COVD-19 pandemic, which posed a major challenge for cancer centers seeking to provide care during an extremely dynamic clinical and political situation which requires maximum flexibility to be appropriately managed.

Renal sinus fat invasion in pT3a clear cell renal cell carcinoma affects outcomes of patients without nodal involvement or distant metastases.

PURPOSE: According to the 2002 American Joint Committee on Cancer TNM classification, perinephric and renal sinus fat invasion are classified as pT3a renal cell carcinoma. However, only a few studies have assessed the impact of sinus fat invasion on patient survival and with controversial results. We analyzed the impact of sinus fat invasion on cancer specific survival in a cohort of patients with pT3a clear cell renal cell carcinoma. MATERIALS AND METHODS: We retrospectively analyzed data on 115 consecutive patients treated with open radical nephrectomy for unilateral, sporadic pT3a clear cell renal cell carcinoma at our department from 1989 to 2006. All pathological specimens were rereviewed by a single uropathologist. The prognostic role of sinus fat invasion in cancer specific survival was assessed by Cox proportional hazards regression models. RESULTS: Ten patients had direct ipsilateral adrenal invasion and were excluded from analysis. A total of 105 patients with clear cell renal cell carcinoma were evaluated. Median followup was 38 months. In the overall population sinus fat invasion did not reach independent predictive status in terms of cancer specific survival on multivariate Cox regression analysis after adjusting for age, performance status, tumor dimension, tumor grade, synchronous metastases, nodal involvement, sarcomatoid differentiation and coagulative necrosis. In the subset of patients with pNx/pN0 M0 (83) the actuarial 5-year cancer specific survival was 71.9% and 45.5% for those with perinephric fat invasion only and sinus fat invasion, respectively (p = 0.025). Sinus fat invasion achieved an independent predictive role on multivariable Cox regression analysis (p = 0.048, HR 2.06). CONCLUSIONS: Sinus fat invasion in clear cell renal cell carcinoma significantly affects cancer specific survival in patients without nodal or distant metastases. However, sinus fat invasion is not associated with worse cancer specific survival in cases of metastatic disease.

Pain and discomfort after Retzius-sparing robot-assisted radical prostatectomy: a comparative study between suprapubic cystostomy and urethral catheter as urinary drainage.

BACKGROUND: The aim of this study is to evaluate differences in discomfort, complications and functional results after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) according to different urinary drainage: suprapubic tube (SPT) and standard urethral catheter (UC). METHODS: Prospective, comparative, consecutive, non-randomized study. In all patients with a water-tight anastomosis, no hematuria, obesity, previous suprapubic surgery or history of bladder cancer, a SPT (two-way Foley 14-Fr catheter) was positioned instead of a Foley 18-Fr UC. One week after surgery, an institutional self-compiled questionnaire was administered. The patients were divided into two groups according to the presence of UC or SPT and were compared concerning pain, perioperative results, complications, functional outcomes. RESULTS: Fifty-six patients with UC and 135 with SPT agreed to participate to the study. Median postoperative pain score was 3 (IQR: 2-5) in UC and 3 (IQR: 1-5) in SPT group (P=0.324); urinary drain-related pain scores were 3 (IQR: 1-5) in UC and 1 (IQR: 0-3) in SPT groups (P<0.001); catheter removal related scores were 1 (IQR: 0-3) and 1 (IQR: 1-3) (P=0.317), respectively. Lastly, 17.8% (UC) and 31.1% (SPT) wore a protection (small or medium pad) while the urinary drainage was in place (P=0.061). No differences related to complications were found (P=0.085); 7.9% of patients in UC group and 4.2% in SPT group (P=0.178) used pads one year after surgery. CONCLUSIONS: We demonstrated suprapubic tube to be more comfortable than transurethral catheter after RARP, with a possible advantage concerning anastomotic postoperative problems.

Technical features and the demonstrated advantages of the Retzius sparing robotic prostatectomy.

OBJECTIVE: Robot-assisted laparoscopic  radical prostatectomy (RARP) is nowadays considered  the main surgical option for localized prostate cancer (PCa). We recently developed a new approach for RARP  avoiding all the Retzius structures involved in continence  and potency preservation, the so called Retzius-sparing  technique (RSP). The objective of the paper is to report technical aspects and functional results of RSP.  METHODS: We evaluated our data and available literature  regarding RSP, functional results and advantages.  RESULTS: RSP is oncologically safe and guarantee high early continence rates. CONCLUSION: Long-term, prospective, comparative,  and possibly randomized studies are needed but RSP is  now spreading all over the world thanks to the different advantages that offers to patients. The most recognized benefit is surely the achievement of early continence, as well documented in multiple studies and papers, without compromising the oncological outcomes.

Does prostate volume have an impact on the functional and oncological results of Retzius-sparing robot-assisted radical prostatectomy?

BACKGROUND: The objective of our study is to evaluate the effect of prostatic volume on the outcomes of Retzius-sparing robot-assisted radical prostatectomy (RSP). METHODS: All the consecutive patients undergoing RSP up to January 2015 were included. The series was divided into three groups based on prostate weight at radical prostatectomy specimen (<40 g, 40-60 g, >60 g). Perioperative, oncological and functional data were prospectively recorded. Potency was defined as erections sufficient for penetration; continence as no pad or one safety liner. Oncological results were reported as positive surgical margins (PSMs) and 1-year biochemical disease-free survival (PSA<0.2 ng/mL). RESULTS: We evaluated 750 patients (366 with <40 g prostates, 272 with 40-60 g prostates, 112 with >60 g prostates). Median follow-up was 22 months; PSA was higher in larger prostates (6.6 vs. 6.8 vs. 8 ng/mL). Nerve-sparing and bladder-neck sparing procedures were in similar percentages. Larger prostates required longer surgeries (90 vs. 100 vs. 100 minutes, P=0.002). Perioperative results were similar (blood loss, discharge, complications, catheter removal). Larger prostates had more frequently localized disease (pT2 in 49.5% vs. 60.7% vs. 68.5%; P=0.001); PSMs were similar both in pT2 (15.5% vs. 9.4% vs. 11.8%) and in pT3 cases (40.1% vs. 42% vs. 34%). In the three study groups, immediate continence was reached by 88%, 89.5% and 81.3% (P=0.045), while no differences were observed concerning continence (93.4%, 94.1%, 94.7%; P=0.892) or potency after follow-up. CONCLUSIONS: RSP is feasible in patients with prostates of any volume, with similar oncological and functional outcomes. Despite being inferior to the figures obtained in low volume prostates, the very high immediate continence rates observed in larger prostates encourage the use of this approach also in larger prostates.

Follow-up of elderly patients with urogenital cancers: Evaluation of geriatric care needs and related actions.

OBJECTIVES: To investigate a comprehensive geriatric assessment (CGA) with subsequent investigation of healthcare patterns in older patients with urological cancers undergoing initial surgery or radiotherapy, to verify the usefulness of the incorporation of geriatric principles in future care plans. MATERIAL AND METHODS: This is a prospective cohort study. From November 2011 to March 2015, CGA was offered to all patients aged 70+ years treated with radiotherapy or surgery at seven tertiary centers. Patients were classified as fit, vulnerable, or frail according to Balducci's definition. CGA and follow-up data were collected by two trained evaluators at 6 and 12months. The information collected was not available to the caring physicians during follow-up. RESULTS: CGA was performed in 453 patients with prostate cancer (295), bladder cancer (126), or kidney cancer (32). 40% of patients with prostate cancer were fit, 47% vulnerable, and 13% frail. The corresponding values for renal cancer were 25%, 40%, and 34%, and for bladder cancer, 21%, 42%, and 37%. During follow-up, 60% of patients with cardiac diseases, 42% of those with diabetes/other metabolic disorders, 35% of those with hypertension, and 35% of those with respiratory diseases were followed by a specialist (for these severe/extremely severe comorbidities). Of 16 patients with ADL impairment and 63 with IADL impairment, only 4 (25%) and 6 (10%), respectively, were referred to a rehabilitation service. Only one case was referred to a geriatrician. CONCLUSIONS: Appropriate clinical care patterns are advisable to improve quality of survivorship in older patients with urological cancers.

Life-threatening complications after ureteroscopy for urinary stones: survey and systematic literature review.

INTRODUCTION: Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semi-rigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS). EVIDENCE ACQUISITION: Experienced endourologists (more than 75 cases/year in the last 3 years) we enrolled, and a survey was performed asking to review their series and report the cases encumbered by major complications (Clavien-Dindo IIIb-IV grade). A literature search was also conducted in the Medline (PubMed) and Cochrane Libraries databases in July, 2016 to identify all studies reporting the presence of major complications in patients underwent URS procedures. A PubMed search was performed using the following key words in combination: "kidney injury," "ureteroscopy," "nephrectomy," "life-threatening," "urinary stones," "complications." EVIDENCE SYNTHESIS: Eleven urologists reported on 12 major complications (4 after s-URS, 8 after f-URS). Eight patients developed a kidney injury, 1 an arteriovenous fistula, 2 a ureter avulsion and 1 acute sepsis. Six patients underwent open nephrectomy, two surgical repair, one open pyeloplasty, one coil artery embolization and two superselective artery embolization. CONCLUSIONS: Guidelines and clinical practice give useful recommendations about intraoperative safety and prevention of life-threatening events. The careful postoperative observation and the surgical active treatment of this complications play a key role in reducing morbidity, kidney loss and mortality. This study encourages a strict and active care of patients, supports a routine reporting of complications, and highlights the need for systematic use of standardized classification systems.

Beyond the learning curve of the Retzius-sparing approach for robot-assisted laparoscopic radical prostatectomy: oncologic and functional results of the first 200 patients with ≥ 1 year of follow-up.

BACKGROUND: Robot-assisted laparoscopic radical prostatectomy (RARP) has become the main surgical option for localized prostate cancer. We recently developed a new approach for RARP, passing through the pouch of Douglas and avoiding all the Retzius structures involved in continence and potency preservation. OBJECTIVE: To report the functional and oncologic results of our first 200 patients operated on using this new approach. DESIGN, SETTING, AND PARTICIPANTS: This was a prospective, noncontrolled case series including the first 200 consecutive patients undergoing this kind of surgery (January the 1st, 2010 to December the 31st, 2011). SURGICAL PROCEDURE: Retzius-sparing RARP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: All perioperative, oncologic, and functional data were prospectively recorded. Potency was defined as an International Index of Erectile Function-5 questionnaire score >17; continence was defined as use of no pad or of one safety liner. Oncologic results were reported as positive surgical margins (PSM) and 1-yr biochemical disease-free survival (1y-bDFS). Recurrence was defined as a repeated prostate-specific antigen >0.2 ng/ml. Complications were graded according to the Clavien-Dindo system. The first 100 patients (group 1) were compared with the second 100 (group 2) to evaluate the learning curve effects. RESULTS AND LIMITATIONS: The median patient age was 65 yr. Comparing the two groups, transfusions were needed in 8% versus 4% of cases in groups 1 and 2, respectively (p=0.02). There was one Clavien-Dindo grade 3b in group 1 versus one grade 3a complication in group 2. In patients with pT2 disease, PSMs were recorded in 22.4% of those in group 1 versus 10.1% in group 2 (p=0.045). 1y-bDFS was 89% in group 1 versus 92% in group 2. For groups 1 and 2, respectively, immediate continence was reached in 92% versus 90% of patients, and the 1-yr continence rate was 96% versus 96%. Considering the 77 potent patients aged <65 yr who underwent bilateral intrafascial nerve-sparing surgery, 40.4% of those in group 1 versus 40% of those in group 2 reached their first intercourse within 1 mo; at 1 yr of follow-up, these figures had increased to 81% versus 71%, respectively (p=0.162). The main limitation of this study is its noncontrolled nature. CONCLUSIONS: We demonstrated Retzius-sparing RARP to be oncologically safe and to result in high early continence and potency rates. Long-term, prospective, comparative, and possibly randomized studies are needed.

Impact of venous tumour thrombus consistency (solid vs friable) on cancer-specific survival in patients with renal cell carcinoma.

BACKGROUND: To our knowledge, the impact of venous tumour thrombus (VTT) consistency in patients affected by renal cell carcinoma (RCC) has never been addressed. OBJECTIVE: To analyse the effect of VTT consistency on cancer-specific survival (CSS). DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analysed 174 consecutive patients with RCC and renal vein or inferior vena cava (IVC) VTT who underwent surgical treatment between 1989 and 2007 at our institute. INTERVENTION: All patients underwent radical nephrectomy and thrombectomy. MEASUREMENTS: Pathologic specimens were reviewed by a single uropathologist. In addition to traditional pathologic features, the morphologic aspect of the tumour thrombus was evaluated to distinguish solid from friable patterns. The prognostic role of thrombus consistency (solid vs friable) on CSS was assessed by means of Cox regression models. RESULTS AND LIMITATIONS: The VTT was solid in 107 patients (61.5%) and friable in 67 patients (38.5%). The presence of a friable VTT increased the risk of having synchronous nodal or distant metastases, higher tumour grade, higher pathologic stage, and simultaneous perinephric fat invasion (all p < 0.05). The median follow-up was 24 mo. The median CSS was 33 mo; the median CSS was 8 mo in patients with a friable VTT and 55 mo in patients with a solid VTT (p < 0.001). On multivariable analyses, the presence of a friable VTT was an independent predictor of CSS (p = 0.02). The power of our conclusion may be somewhat limited by the relatively small study population and the retrospective nature of the study. CONCLUSIONS: In patients with RCC and VTT, the presence of a friable thrombus is an independent predictor of CSS. If our finding is confirmed by further studies, the consistency of the tumour thrombus should be introduced into routine pathologic reports to provide better patient risk stratification.

A new anatomic approach for robot-assisted laparoscopic prostatectomy: a feasibility study for completely intrafascial surgery.

Robot-assisted laparoscopic prostatectomy (RALP) has been disseminated widely, changing the knowledge of surgical anatomy of the prostate. The aim of our study is to demonstrate the feasibility of a new, purely intrafascial approach. The Bocciardi approach for RALP passes through the Douglas space, following a completely intrafascial plane without any dissection of the anterior compartment, which contains neurovascular bundles, Aphrodite's veil, endopelvic fascia, the Santorini plexus, pubourethral ligaments, and all of the structures thought to play a role in maintenance of continence and potency. In this case series, we present our first five patients undergoing the Bocciardi approach for RALP. We report the results of our technique in three patients following two unsuccessful attempts. No perioperative major complication was recorded. Pathologic stage was pT2c in two patients and pT2a in one patient, with no positive surgical margin. The day after removing the catheter, two of the three patients reported use of a single, small safety pad, and one patient was discharged without any pad. One patient reported an erection the day after removing the catheter. The anatomic rationale for better results compared with traditional RALP is strong, but well-designed studies are needed to evaluate the advantages of our technique.

Radical nephrocapsulectomy and caval thrombectomy with extracorporeal circulation and deep hypothermic circulatory arrest in right anterior minithoracotomy: a minimally invasive approach.

OBJECTIVES: Radical nephrocapsulectomy and cavoatrial thrombectomy with median sternotomy and abdominal access, using extracorporeal circulation (ECC) and deep hypothermic circulatory arrest (DHCA), has become the gold standard treatment for renal cell carcinoma (RCC) with neoplastic thrombosis of the suprahepatic and intrapericardial inferior vena cava (IVC) and right atrium (RA). Any modification of surgical techniques should be compared with this therapeutic strategy. METHODS: In our quest to identify a minimally invasive approach and to apply available technology to ensure patient safety, even in cases of RCC with suprahepatic IVC and RA thrombosis, we identified a therapeutic approach that foresees en bloc radical nephrocapsulectomy, with ECC and DHCA in right anterior minithoracotomy. Furthermore, to make surgery even safer, we made some modifications and used auxiliary maneuvers. We present the case of a 39-year-old man with a neoplasm that involved the right kidney and suprahepatic IVC thrombosis, undergoing radical nephrocapsulectomy and thrombectomy with ECC and DHCA in right anterior minithoracotomy. CONCLUSIONS: Radical nephrocapsulectomy and thrombectomy of the suprahepatic and intrapericardial IVC and/or of the RA with ECC and DHCA in right anterior minithoracotomy for RCC is a valid minimally invasive alternative to standard surgical techniques. Compared with standard median sternotomy access, right anterior minithoracotomy allows a more rapid functional recovery, a reduction in risk of infection of the wound, and a reduction in pain during postoperative convalescence, and has considerable esthetic advantages, without limiting surgical therapeutic chances, regardless of the cranial extension of the thrombus.
