Simultaneous robotic partial nephrectomy for bilateral renal masses.

PURPOSE: There is currently no consensus regarding the optimal treatment strategy for patients presenting with synchronous bilateral renal masses. The decision to perform bilateral procedures on the same intervention or in staged procedures is debated. The aim of this manuscript is to analyse the outcomes of simultaneous robot-assisted partial nephrectomy (RAPN) in a series of patients with bilateral renal masses treated at five Italian robotic institutions. METHODS: Data from a prospectively maintained multi-institutional database on patients subjected to simultaneous RAPN between November 2011 and July 2019 were reviewed. RAPNs were performed with da Vinci Si or Xi surgical system by expert robotic surgeons. Baseline demographics and clinical features, peri- and post-operative data were collected. RESULTS: Overall, 27 patients underwent simultaneous bilateral RAPN, and 54 RAPNs were performed without need of conversion; median operative time was 250 minutes, median estimated blood loss was 200 mL. Renal artery clamping was needed for 27 (50%) RAPNs with a median warm ischemia time of 15 minutes and no case of acute kidney injury. Complications were reported in 7 (25.9%) patients, mainly represented by Clavien 2 events (6 blood transfusions). Positive surgical margins were assessed in 2 (3.7%) of the renal cell carcinoma. At the median follow-up of 30 months, recurrence-free survival was 100%. CONCLUSION: Our data showed that, in selected patients and expert hands, simultaneous bilateral RAPNs could be a safe and feasible procedure with promising results for the treatment of bilateral synchronous renal masses.

Protocol of the Italian Radical Cystectomy Registry (RIC): a non-randomized, 24-month, multicenter study comparing robotic-assisted, laparoscopic, and open surgery for radical cystectomy in bladder cancer.

BACKGROUND: Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24 months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence. METHODS: We describe a protocol for an observational, prospective, multicenter, cohort study to assess patients affected by bladder neoplasms undergoing radical cystectomy and urinary diversion. The Italian Radical Cystectomy Registry is an electronic registry to prospectively collect the data of patients undergoing radical cystectomy conducted with any technique (open, laparoscopic, robotic-assisted). Twenty-eight urology departments across Italy will provide data for the study, with the recruitment phase between 1st January 2017-31st October 2020. Information is collected from the patients at the moment of surgical intervention and during follow-up (3, 6, 12, and 24 months after radical cystectomy). Peri-operative variables include surgery time, type of urinary diversion, conversion to open surgery, bleeding, nerve sparing and lymphadenectomy. Follow-up data collection includes histological information (e.g., post-op staging, grading, and tumor histology), short- and long-term outcomes (e.g., mortality, post-op complications, hospital readmission, sexual potency, continence etc). DISCUSSION: The current protocol aims to contribute additional data to the field concerning the short- and long-term outcomes of three different radical cystectomy surgical techniques for patients with bladder cancer, including open, laparoscopic, and robot-assisted. This is a comparative-effectiveness trial that takes into account a complex range of factors and decision making by both physicians and patients that affect their choice of surgical technique. TRIAL REGISTRATION: ClinicalTrials.gov , NCT04228198 . Registered 14th January 2020- Retrospectively registered.

The dramatic COVID 19 outbreak in Italy is responsible of a huge drop of urological surgical activity: a multicenter observational study.

OBJECTIVE: To describe the trend in surgical volume in urology in Italy during the coronavirus disease 2019 (COVID-19) outbreak, as a result of the abrupt reorganisation of the Italian national health system to augment care provision to symptomatic patients with COVID-19. METHODS: A total of 33 urological units with physicians affiliated to the AGILE consortium (Italian Group for Advanced Laparo-Endoscopic Surgery; www.agilegroup.it) were surveyed. Urologists were asked to report the amount of surgical elective procedures week-by-week, from the beginning of the emergency to the following month. RESULTS: The 33 hospitals involved in the study account overall for 22 945 beds and are distributed in 13/20 Italian regions. Before the outbreak, the involved urology units performed overall 1213 procedures/week, half of which were oncological. A month later, the number of surgeries had declined by 78%. Lombardy, the first region with positive COVID-19 cases, experienced a 94% reduction. The decrease in oncological and non-oncological surgical activity was 35.9% and 89%, respectively. The trend of the decline showed a delay of roughly 2 weeks for the other regions. CONCLUSION: Italy, a country with a high fatality rate from COVID-19, experienced a sudden decline in surgical activity. This decline was inversely related to the increase in COVID-19 care, with potential harm particularly in the oncological field. The Italian experience may be helpful for future surgical pre-planning in other countries not so drastically affected by the disease to date.

A comparative propensity score-matched analysis of perioperative outcomes of intracorporeal vs extracorporeal urinary diversion after robot-assisted radical cystectomy: results from the International Robotic Cystectomy Consortium.

OBJECTIVE: To compare the perioperative outcomes of intracorporeal (ICUD) vs extracorporeal urinary diversion (ECUD) after robot-assisted radical cystectomy (RARC). PATIENTS AND METHODS: We retrospectively reviewed the prospectively maintained International Robotic Cystectomy Consortium (IRCC) database. A total of 972 patients from 28 institutions who underwent RARC were included. Propensity score matching was used to match patients based on age, gender, body mass index (BMI), American Society of Anesthesiologists Score (ASA) score, Charlson Comorbidity Index (CCI) score, prior radiation and abdominal surgery, receipt of neoadjuvant chemotherapy, and clinical staging. Matched cohorts were compared. Multivariate stepwise logistic and linear regression models were fit to evaluate variables associated with receiving ICUD, operating time, 90-day high-grade complications (Clavien-Dindo Classification Grade ≥III), and 90-day readmissions after RARC. RESULTS: Utilisation of ICUD increased from 0% in 2005 to 95% in 2018. The ICUD patients had more overall complications (66% vs 58%, P = 0.01) and readmissions (27% vs 17%, P = 0.01), but not high-grade complications (21% vs 24%, P = 0.22). A more recent RC era and ileal conduit diversion were associated with receiving an ICUD. Higher BMI, ASA score ≥3, and receiving a neobladder were associated with longer operating times. Shorter operating time was associated with male gender, older age, ICUD, and centres with a larger annual average RC volume. Longer intensive care unit stay was associated with 90-day high-grade complications. Higher CCI score, prior radiation therapy, neoadjuvant chemotherapy, and ICUD were associated with a higher risk of 90-day readmissions. CONCLUSIONS: Utilisation of ICUD has increased over the past decade. ICUD was associated with more overall complications and readmissions compared to ECUD, but not high-grade complications.

External validation of Cormio nomogram for predicting all prostate cancers and clinically significant prostate cancers.

PURPOSE: Recently, the Cormio et al. nomogram has been developed to predict prostate cancer (PCa) and clinically significant PCa using benign prostatic obstruction parameters. The aim of the present study was to externally validate the nomogram in a multicentric cohort. METHODS: Between 2013 and 2019, patients scheduled for ultrasound-guided prostate biopsy were prospectively enrolled at 11 Italian institutions. Demographic, clinical and histological data were collected and analysed. Discrimination and calibration of Cormio nomogram were assessed with the receiver operator characteristics (ROC) curve and calibration plots. The clinical net benefit of the nomogram was assessed with decision curve analysis. Clinically significant PCa was defined as ISUP grade group > 1. RESULTS: After accounting for inclusion criteria, 1377 patients were analysed. 816/1377 (59%) had cancer at final pathology (574/816, 70%, clinically significant PCa). Multivariable analysis showed age, prostate volume, DRE and post-voided residual volume as independent predictors of any PCa. Discrimination of the nomogram for cancer was 0.70 on ROC analysis. Calibration of the nomogram was excellent (p = 0.94) and the nomogram presented a net benefit in the 40-80% range of probabilities. Multivariable analysis for predictors of clinically significant PCa found age, PSA, prostate volume and DRE as independent variables. Discrimination of the nomogram was 0.73. Calibration was poor (p = 0.001) and the nomogram presented a net benefit in the 25-75% range of probabilities. CONCLUSION: We confirmed that the Cormio nomogram can be used to predict the risk of PCa in patients at increased risk. Implementation of the nomogram in clinical practice will better define its role in the patient's counselling before prostate biopsy.

A comparison among PCNL, Miniperc and Ultraminiperc for lower calyceal stones between 1 and 2 cm: a prospective, comparative, multicenter and randomised study.

BACKGROUND: Conventional Percutaneous Lithotripsy (PCNL) has been an effective, successful and easy approach for especially > 1 cm sized calyceal stones however risks of complications and nephron loss are inevitable. Our aim is to compare the efficacy and safety of PCNL, MiniPerc (MP) and UltraMiniPerc (UMP) for lower calyceal stones between 1 and 2 cm with a multicenter prospective randomized study. METHODS: Between January 2015 and June 2018, 132 consecutive patients with single lower calyceal stone were enrolled. Patients were randomized in three groups; A: PCNL; B: MP; C: UMP. 44 patients for the Group A, 47 for Group B and 41 for Group C. Exclusion criterias were the presence of coagulation impairments, age of < 18 or > 75, presence of infection or serious comorbidities. Patients were controlled with computerized tomography scan after 3 months. A negative CT or an asymptomatic patient with stone fragments < 3 mm size were the criteria to assess the stone-free status. Patient characteristics, stone free rates (SFR) s, complications and re-treatment rates were analyzed. RESULTS: The mean stone size were 16.38, 16.82 and 15.23 mm respectively in Group A, B and C(p = 0.34). The overall SFR was significantly higher in Group A (86.3%) and B (82.9%) as compared to Group C (78%)(p < 0.05). The re-treatment rate was significantly higher in Group C (12.1%) and complication rates was higher in Group A (13.6%) as compared to others(p < 0.05). The hospitalization was significantly shorter in Group C compared to Group A (p = 0.04). CONCLUSIONS: PCNL and MP showed higher efficacy than UMP to obtain a better SFR. Auxiliary and re-treatment rates were higher in UMP. On the other hand for such this kind of stones PCNL had more complications. Overall evaluation favors MP as a better indication in stones 1-2 cm size.

Urology in the Time of Coronavirus: Reduced Access to Urgent and Emergent Urological Care during the Coronavirus Disease 2019 Outbreak in Italy.

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.

Performance Improvement (Pi) score: an algorithm to score Pi objectively during E-BLUS hands-on training sessions. A European Association of Urology, Section of Uro-Technology (ESUT) project.

OBJECTIVE: To evaluate the variability of subjective tutor performance improvement (Pi) assessment and to compare it with a novel measurement algorithm: the Pi score. MATERIALS AND METHODS: The Pi-score algorithm considers time measurement and number of errors from two different repetitions (first and fifth) of the same training task and compares them to the relative task goals, to produce an objective score. We collected data during eight courses on the four European Association of Urology training in Basic Laparoscopic Urological Skills (E-BLUS) tasks. The same tutor instructed on all courses. Collected data were independently analysed by 14 hands-on training experts for Pi assessment. Their subjective Pi assessments were compared for inter-rater reliability. The average per-participant subjective scores from all 14 proctors were then compared with the objective Pi-score algorithm results. Cohen's κ statistic was used for comparison analysis. RESULTS: A total of 50 participants were enrolled. Concordance found between the 14 proctors' scores was the following: Task 1, κ = 0.42 (moderate); Task 2, κ = 0.27 (fair); Task 3, κ = 0.32 (fair); and Task 4, κ = 0.55 (moderate). Concordance between Pi-score results and proctor average scores per participant was the following: Task 1, κ = 0.85 (almost perfect); Task 2, κ = 0.46 (moderate); Task 3, κ = 0.92 (almost perfect); Task 4 = 0.65 (substantial). CONCLUSION: The present study shows that evaluation of Pi is highly variable, even when formulated by a cohort of experts. Our algorithm successfully provided an objective score that was equal to the average Pi assessment of a cohort of experts, in relation to a small amount of training attempts.

Developing a five-step training model for transperineal prostate biopsies in a naïve residents' group: a prospective observational randomised study of two different techniques.

PURPOSE: To evaluate a five-step training model for transperineal prostate biopsies (TPPB) and the differences in terms of the detection rate (DR) and the ease of execution when using either the "fan technique" (FT) or the use of a Free Hand technique (FH). METHODS: A prospective observational randomised study was conducted from September 2015 to November 2017. Six naïve residents, who underwent the same five-steps training model, were randomly subdivided into two different groups of three residents based on the selected TPPB technique: A (FT) and B (FH). Patient characteristics (age, PSA, prostatic volume, DRE, MRI), intraoperative (operative time, number of samples) and postoperative parameters (histologic, pain) were evaluated in the 2 groups. The overall and stratified DR for PSA ranges and prostate volume (PV), operative time and complications were compared. RESULTS: The overall detection rate was very high in both groups (FT 58.2% vs FH 59.6%) and not statistically different between the two techniques. There were no differences in terms of complication rates and pain. The FH showed a better detection rate in prostates smaller than 40 cc (p = 0.023) and a faster operative time (p = 0.025) compared to FT. CONCLUSIONS: Within the TPPB, FH is associated with a higher detection rate in patients with prostate < 40 cc compared to an FT when performed by inexperienced trainees. Standardised training organised in consecutive steps seems to contribute to the achievement of overall high detection rates with both methods.

Development of a patient and institutional-based model for estimation of operative times for robot-assisted radical cystectomy: results from the International Robotic Cystectomy Consortium.

OBJECTIVES: To design a methodology to predict operative times for robot-assisted radical cystectomy (RARC) based on variation in institutional, patient, and disease characteristics to help in operating room scheduling and quality control. PATIENTS AND METHODS: The model included preoperative variables and therefore can be used for prediction of surgical times: institutional volume, age, gender, body mass index, American Society of Anesthesiologists score, history of prior surgery and radiation, clinical stage, neoadjuvant chemotherapy, type, technique of diversion, and the extent of lymph node dissection. A conditional inference tree method was used to fit a binary decision tree predicting operative time. Permutation tests were performed to determine the variables having the strongest association with surgical time. The data were split at the value of this variable resulting in the largest difference in means for the surgical time across the split. This process was repeated recursively on the resultant data sets until the permutation tests showed no significant association with operative time. RESULTS: In all, 2 134 procedures were included. The variable most strongly associated with surgical time was type of diversion, with ileal conduits being 70 min shorter (P < 0.001). Amongst patients who received neobladders, the type of lymph node dissection was also strongly associated with surgical time. Amongst ileal conduit patients, institutional surgeon volume (>66 RARCs) was important, with those with a higher volume being 55 min shorter (P < 0.001). The regression tree output was in the form of box plots that show the median and ranges of surgical times according to the patient, disease, and institutional characteristics. CONCLUSION: We developed a method to estimate operative times for RARC based on patient, disease, and institutional metrics that can help operating room scheduling for RARC.

Guidance on patient consultation. Current evidence for prostate-specific antigen screening in healthy men and treatment options for men with proven localised prostate cancer.

The main objective of this review is to summarise, for primary and secondary care doctors, the management options and current supporting evidence for clinically localised prostate cancer. We review all aspects of management including current guidelines on early cancer detection and the importance of informed consent on PSA-based screening and assess the most common treatment options and the evidence for managing patients with low-, medium-, and high-risk disease.

Costs analysis of laparoendoscopic, single-site laparoscopic and open surgery for cT1 renal masses in a European high-volume centre.

OBJECTIVE: To analyse intraoperative costs and healthcare reimbursements of partial/radical nephrectomy in open and minimal invasive surgery (MIS), as laparoscopy and laparoendoscopic single-site surgery (LESS), for the treatment of renal tumour. MATERIALS AND METHODS: In a non-randomized retrospective study, we selected 90 patients who underwent (01/2010-12/2011) partial and radical nephrectomy for clinical renal masses ≤7 cm (cT1N0M0) and divided them into laparoscopic [laparoscopic partial nephrectomy (LPN), laparoscopic radical nephrectomy (LRN)], LESS [laparoendoscopic single-site partial nephrectomy (LESS-PN), laparoendoscopic single-site radical nephrectomy (LESS-RN)] and open groups [open partial nephrectomy (OPN), open radical nephrectomy (ORN)]. Patients were matched for age, sex, body mass index, ASA score and tumour side. Primary endpoints were evaluation of intraoperative costs (general, laparoscopic, sutures, haemostatic agents, anaesthesia, and surgeon/nurses fee), total insurance and estimated daily reimbursement. RESULTS: MIS showed longer operative time (p ≤ .02) and shorter hospital stay (p ≤ .04). Total costs were higher (p ≤ .03) in MIS (LRN: 4,091.5 ; LPN: 4,390.4 ; LESS-RN: 3,866 ; and LESS-PN: 3,450 ) if compared with open (OPN: 2,216.8.8 , ORN: 1,606.4 ). Laparoscopic materials incised mainly in total costs of MIS (38-58.1 %). Reusable instruments reduced LESS laparoscopic costs (LESS-PN: 1,312.2 vs. LRN: 2,212.2 , p < .0001). Intraoperative frozen section and DJ ureteric stenting (general costs) (p ≤ .008) and haemostatic agents use (p ≤ .01) were higher in nephron sparing surgery (NSS), due to more frequent use of ancillary procedures necessary for a safe management of such an approach. Estimated anaesthesia costs and doctor/nurses fee were higher in MIS (p ≤ .02). Whereas total final reimbursements were comparable (p ≥ .8), estimated daily reimbursements were lower in MIS (p < .001) due to higher intraoperative costs and longer operative time. CONCLUSION: Well-known advantages offered by MIS/NSS face higher total intraoperative costs and 'paradoxical' reduced healthcare reimbursement. We believe that local health systems should consider a subclassification with different compensations, which will incentive NSS and MIS approaches.

Open versus Robot-Assisted Radical Cystectomy for the Treatment of pT4a Bladder Cancer: Comparison of Perioperative Outcomes.

We compared the perioperative outcomes of open (ORC) vs. robot-assisted (RARC) radical cystectomy in the treatment of pT4a MIBC. In total, 212 patients underwent ORC (102 patients, Group A) vs. RARC (110 patients, Group B) for pT4a bladder cancer. Patients were prospectively followed and retrospectively reviewed. We assessed operative time, estimated blood loss (EBL), intraoperative and postoperative complications, length of stay, transfusion rate, and oncological outcomes. Preoperative features were comparable. The mean operative time was 232.8 vs. 189.2 min (p = 0.04), and mean EBL was 832.8 vs. 523.7 mL in Group A vs. B (p = 0.04). An intraoperative transfusion was performed in 32 (31.4%) vs. 11 (10.0%) cases during ORC vs. RARC (p = 0.03). The intraoperative complications rate was comparable. The mean length of stay was shorter after RARC (12.6 vs. 7.2 days, p = 0.02). Postoperative transfusions were performed in 36 (35.3%) vs. 13 (11.8%) cases (p = 0.03), and postoperative complications occurred in 37 (36.3%) vs. 29 (26.4%) patients in Groups A vs. B (p = 0.05). The positive surgical margin (PSM) rate was lower after RARC. No differences were recorded according to the oncological outcomes. ORC and RARC are feasible treatments for the management of pT4a bladder tumors. Minimally invasive surgery provides shorter operative time, bleeding, transfusion rate, postoperative complications, length of stay, and PSM rate.

Laparoscopic vs open partial nephrectomy for T1 renal tumours: evaluation of long-term oncological and functional outcomes in 340 patients.

OBJECTIVE: To evaluate the long-term oncological and functional outcomes of laparoscopic partial nephrectomy (LPN) compared with open partial nephrectomy (OPN) for pT1 renal tumours. PATIENTS AND METHODS: In this retrospective single-centre study, 340 consecutive patients underwent LPN and OPN for localized, incidentally discovered, renal masses of <7 cm (cT1). The patients were matched for age, sex, body mass index, American Society of Anesthesiology score, tumour side (right or left kidney) and tumour characteristics (RENAL nephrometry score). Demographic data, peri- and postoperative variables, including operating time, estimated blood loss, complications, hospital stay, renal function, histological tumour staging and grading, and metastasis rates were collected and analysed. RESULTS: The median (SEM) operating time for LPN and OPN was 145.3 (45.4) min and 155.2 (35.6) min, respectively (P = 0.07). The median (SEM) warm ischaemia time was 11.7 (2.2) min in the LPN and 14.4 (1.9) min in the OPN group (P = 0.03). The median (SEM) RENAL nephrometry scores for LPN and OPN were 5.9 (1.6) and 6.1 (0.3), respectively (P = 0.11). During follow-up, the biochemical markers of glomerular filtration were completely normalized, showing the absence of renal injury and there was no significant difference in glomerular filtration rate between the groups, with median (SEM) rates of 79.8 (3.0) mL/min/1.72 m(2) for the LPN and 80.2 (2.7) mL/min/1.72 m(2) for the OPN group at 5-year follow-up. The 5-year overall survival and cancer-specific survival rates, calculated using the Kaplan-Meier method, were 94% and 91% in the LPN group, and 92% and 88% in the OPN group. CONCLUSION: LPN and OPN provide similar long-term oncological outcomes in the therapy of T1 renal cancer. With regard to renal function, no damage to the kidney was found after LPN and OPN, with a complete normalization of renal function at the 5-year follow-up in both groups.

Laparoscopic versus open bilateral intrafascial nerve-sparing radical prostatectomy after TUR-P for incidental prostate cancer: surgical outcomes and effect on postoperative urinary continence and sexual potency.

OBJECTIVE: To evaluate the surgical and functional outcomes in nerve-sparing laparoscopic radical prostatectomy (nsLRPT) and nerve-sparing retropubic radical prostatectomy (nsRRPT) after TUR-P for incidental prostate cancer. MATERIALS AND METHODS: Between January 2003 and August 2011, 125 nsLRPT and 128 nsRRPT for incidental prostate cancer diagnosed after TUR-P were performed at our clinic. Demographic data, peri- and postoperative measurements and functional outcomes were compared. RESULTS: The mean operative time was 153.1 ± 35.4 min for nsLRPT and 122.5 ± 67.5 min for nsRRPT (p = 0.03). The mean catheterization time was 8 ± 1 days in the laparoscopic group and 11 ± 2 days in the open group (p = 0.02). Also, the length of hospitalization presents statistical significant difference in the two groups. Positive margins were detected in 2.4 and 4.7% of patients with pT2c tumours in the laparoscopic and open groups, respectively (p = 0.09). At a mean follow-up of 26.9 ± 9.3 months for the nsLRPT group and of 27.8 ± 9.7 months for the nsRRPT group, all patients were alive with no evidence of tumour recurrence. Twelve months postoperatively, complete continence was reported in 96.8% of patients who underwent an nsLRPT and in 89.4% of patients in the nsRRPT group (p = 0.02). At that time, 74.4% of patients in the nsLRPT group and 53.1% in the nsRRPT group reported the ability to engage in sexual intercourse (p = 0.0004). CONCLUSION: nsLRPT after TUR-P, performed by expert surgeons, results to be a safe procedure with excellent functional outcomes with regard to the urinary continence and sexual potency.

New trends in minimally invasive urological surgery: what is beyond the robot?

PURPOSE: To review the minimal-invasive development of surgical technique in urology focusing on nomenclature, history and outcomes of Laparo-Endoscopic Single-site Surgery (LESS), Natural Orifice Translumenal Endoscopic Surgery (NOTES) and Computer-Assisted Surgery (CAS). METHODS: A comprehensive literature search was conducted in order to find article related to LESS, NOTES and CAS in urology. The most relevant papers over the last 10 years were selected in base to the experience from the panel of experts, journal, authorship and/or content. RESULTS: Seven hundred and fifty manuscripts were found. Papers on LESS describe feasibility/safety in most of the procedures with a clinical experience of more than 300 cases and five compared results to standard laparoscopy without showing significant differences. NOTES accesses have been proved their feasibility/safety in experimental study. In human, the only procedures performed are on kidney and through a hybrid-Transvaginal route. New robots overcome the main drawbacks of the DaVinci® platform. The use of CAS is increasing its popularity in urology. CONCLUSIONS: LESS has been applied in clinical practice, but only ongoing technical and instrumental refinement will define its future role and overall benefit. The transition to a clinical application of NOTES seems at present only possible with multiple NOTES access and transvaginal access. Robot and Soft Tissue Navigation appear to be important to improve surgical skills. We are already witness to the advantages offered by the former even if costs need to be redefined based on pending long-term results. The latter will probably upgrade the quality of surgery in a near future.

Small-incision access retroperitoneoscopic technique (SMART) pyeloplasty in adult patients: comparison of cosmetic and post-operative pain outcomes in a matched-pair analysis with standard retroperitoneoscopy: preliminary report.

OBJECTIVES: To present small-incision access retroperitoneoscopic technique pyeloplasty (SMARTp), a novel mini-laparoscopic approach for management of uretero-pelvic junction obstruction (UPJO) in adults including comparison with the standard retroperitoneoscopic technique (SRTp). METHODS: In a non-randomised study, we matched 12 adult patients treated from August to November 2010 by SMARTp with 12 patients treated with SRTp from January to November 2010. Mini-laparoscopic retroperitoneal space was created with a home-made 6-mm balloon trocar. One 6-mm (for 5-mm 30° telescope) and two 3.5-mm trocars (for 3-mm working instrument) were used. SRTp was performed with 11- and 6-mm trocar. Primary endpoints included evaluation of cosmetic appearance and post-operative pain evaluated respectively by the patient and observer scar assessment scale (POSAS) and analogue visual scale (VAS). Secondary endpoints were comparison between operative and functional parameters. RESULTS: Cosmetic cumulative results were statistically significant in favour of SMARTp (POSAS: 37.9 vs. 52.4; P = 0.002). A better trend has been shown by post-operative pain (first to fourth day VAS), although not statistically significant (4.2 vs. 4.9, P = 0.891). No differences were recorded in terms of operative time, pre- and post-operative Hb difference, DJ-stent removal and resistive index (RI) improvement. The SMARTp group showed a faster drain removal (2.4 vs. 3.4 day, P = 0.004) and discharge (4.5 vs. 5.4 day P = 0.017). CONCLUSIONS: Preliminary data support SMARTp as safe procedures in experienced hands, providing better cosmetic results compared to SRTp. Further studies and clinical randomised trial performed in a larger population sample are requested.

Minilaparoscopy and laparoendoscopic single-site surgery: mini- and single-scar in urology.

PURPOSE: To review the development of laparoscopic single-site surgery (LESS) and minilaparoscopy (ML), with particular attention to the urological field, focusing on nomenclature, history and outcomes. METHODS: A literature search was conducted on laparoendoscopic single-site surgery, minilaparoscopy, needlescopy and microlaparoscopy. The most relevant papers were selected over the last 30 years. RESULTS: 830 manuscripts were found about LESS, 251 in urology, two CRTs and nine match-case controls. 258 papers were about ML and 55 in urology. ML is the main topic (169 papers), followed by needlescopy (58) and microlaparoscopy (32). The most significant articles are four non-randomized match-case control studies. CONCLUSIONS: Over the last few years, many urological laparoscopic operations have been successfully performed by LESS. However, the actual role of LESS remains to be determined with controversial data about postoperative pain control and almost no results on cosmesis. We are facing second-generation ML with superior performance granted by new endoscopes and most effective instruments. ML has demonstrated in almost all urologic indications to be feasible, safe and able to improve cosmetic and postoperative pain control. Anyway, CRTs are still lacking and only studies from other discipline can corroborate this trend.

Minilaparoscopy, needlescopy and microlaparoscopy: decreasing invasiveness, maintaining the standard laparoscopic approach.

OBJECTIVES: To review the development of miniaturized laparoscopic instruments with particular attention to the urological field and focusing on nomenclature, history and outcomes. METHODS: A comprehensive literature search was conducted in order to find articles related to Minilaparoscopy, Needlescopy, Microlaparoscopy. The most relevant papers over the last 30 years were selected in base to the experience from the panel of experts, journal, authorship and /or content. RESULTS: 258 manuscripts were found, 14 of them review, 126 about general surgery, 86 gynecology, 55 urology, 31 thoracic surgery. Minilaparoscopy is the main topic in 169 papers, Needlescopy in 58 and Microlaparoscopy in 32. No clinical randomized trials are available in urology. Most significant articles are 4 prospective non-randomized match-case control. CONCLUSIONS: We are facing a Minilaparoscopy of second-generation with superior performance granted by new endoscopes and most effective instruments. Up to date, Minilaparoscopy has demonstrated in almost all urologic indication to be feasible, safe and able to improve cosmetic and postoperative pain control. Anyway, clinical randomized trials are still lacking and only studies from other discipline can corroborate this trend.

Prostate cancer testicular metastasis: Are they underestimated? Case report and analysis of the literature.

INTRODUCTION: We aim to present a rare case of a patient who developed a late testicular metastasis of PCa after radical prostatectomy. CASE DESCRIPTION: A 78 years old man presenting for left testicular swelling slowly increasing of size over the last 2 months. He underwent a retropubic radical prostatectomy and extended bilateral lymphadenectomy in 2007 for prostatic adenocarcinoma. At the time of the presentation the last PSA was 0.91 ng/mL. The patient underwent a standard left orchifunicolectomy in April 2019 without intra- or perioperative complications. The pathological analysis showed a testicular metastasis of acinar adenocarcinoma. CONCLUSIONS: In conclusion, testicular metastasis from PCa are uncommon conditions. PSA evaluation and physical examination of all sites of metastasis and accurate evaluation of all signs/symptoms during the clinical visit remains crucial to the diagnosis of recurrence.
