Renal cell carcinoma (RCC) in solitary kidney (SK) represents a challenging scenario. We sought to compare outcomes of robot-assisted partial nephrectomy (RAPN) versus percutaneous thermal ablation (PTA) in SK patients with renal tumors cT1.We performed a multicenter retrospective analysis of SK patients treated for RCC. The PTA group included cryoablation or radiofrequency ablation. We collected baseline characteristics, intraoperative, pathological, and post-operative data. We applied an arbitrary composite "trifecta" to assess surgical, functional, and oncological outcomes, only for malignant histology. RFS analysis was performed using the Kaplan-Meier method. Multivariable regression analysis was performed to determine independent predictors of "trifecta" achievement.We included 198 SK patients (RAPN, n = 50; PTA n = 119). Mean clinical tumor size was not significantly different while R.E.N.A.L. score was higher for RAPN (p 0.001). No differences in intra and major post-procedural complications. Recurrence rate was higher in PTA group but not statistically significant (p 0.328). No difference in metastasis rate was found (p = 0.435). RFS was 96.1% in RAPN and 86.8% in PTA cohort (p = 0.003) while no difference in PFS was detected (p = 0.1). Trifecta was achieved in 72.5% of RAPN vs 77.3% of PTA (p = 0.481). Multivariable analysis has not detected predictors for Trifecta achievement.PTA offers good outcomes in the management of SK patients with RCC. Compared with RAPN, it might carry a higher risk of recurrence; on the other hand, re-treatment is possible. Overall, PTA can be safely offered to treat SK patients presenting RCC. In general, it should be preferred in more frail patients to minimize the risk of complications.

Objectives: Martini et al. developed a nomogram to predict significant (>25%) renal function loss after robot-assisted partial nephrectomy and identified four risk categories. We aimed to externally validate Martini’s nomogram on a large, national, multi-institutional data set including open, laparoscopic, and robot-assisted partial nephrectomy. Methods: Data of 2584 patients treated with partial nephrectomy for renal masses at 26 urological Italian centers (RECORD2 project) were collected. Renal function was assessed at baseline, on third postoperative day, and then at 6, 12, 24, and 48 months postoperatively. Multivariable models accounting for variables included in the Martini’s nomogram were applied to each approach predicting renal function loss at all the specific timeframes. Results: Multivariable models showed high area under the curve for robot-assisted partial nephrectomy at 6- and 12-month (87.3% and 83.6%) and for laparoscopic partial nephrectomy (83.2% and 75.4%), whereas area under the curves were lower in open partial nephrectomy (78.4% and 75.2%). The predictive ability of the model decreased in all the surgical approaches at 48 months from surgery. Each Martini risk group showed an increasing percentage of patients developing a significant renal function reduction in the open, laparoscopic and robot-assisted partial nephrectomy group, as well as an increased probability to develop a significant estimated glomerular filtration rate reduction in the considered time cutoffs, although the predictive ability of the classes was

ObjectiveTo externally validate Yonsei nomogram. MethodsFrom 2000 through 2018, 3526 consecutive patients underwent on-clamp PN for cT1 renal masses at 23 centers were included. All patients had two kidneys, preoperative eGFR >= 60 ml/min/1.73 m2, and a minimum follow-up of 12 months. New-onset CKD was defined as upgrading from CKD stage I or II into CKD stage >= III. We obtained the CKD-free progression probabilities at 1, 3, 5, and 10 years for all patients by applying the nomogram found at . Thereafter, external validation of Yonsei nomogram for estimating new-onset CKD stage >= III was assessed by calibration and discrimination analysis. Results and limitationMedian values of patients' age, tumor size, eGFR and follow-up period were 47 years (IQR: 47-62), 3.3 cm (IQR: 2.5-4.2), 90.5 ml/min/1.73 m2 (IQR: 82.8-98), and 47 months (IQR: 27-65), respectively. A total of 683 patients (19.4%) developed new-onset CKD. The 5-year CKD-free progression rate was 77.9%. Yonsei nomogram demonstrated an AUC of 0.69, 0.72, 0.77, and 0.78 for the prediction of CKD stage >= III at 1, 3, 5, and 10 years, respectively. The calibration plots at 1, 3, 5, and 10 years showed that the model was well calibrated with calibration slope values of 0.77, 0.83, 0.76, and 0.75, respectively. Retrospective database collection is a limitation of our study. ConclusionsThe largest external validation of Yonsei nomogram showed good calibration properties. The nomogram can provide an accurate estimate of the individual risk of CKD-free progression on long-term follow-up.

Objectives Stress urinary incontinence is defined by a complaint of any involuntary loss of urine on effort or physical exertion or on sneezing or coughing and represents a major complication after radical prostatectomy. According to surgical technique, incidence of post-prostatectomy incontinence varies from open (7–39.5%), laparoscopic (5–33.3%) or robotic-assisted (4–31%) approaches. The ProACT® device (Uromedica, Inc., MN) is a possible surgical option for the treatment of this condition. Methods We retrospectively analyzed surgical records of consecutive patients underwent ProACT® implantation in our department between January 2006 to November 2010. We collected data at 6 and 12 months after surgical approach about the daily pad use, International Prostatic Symptoms Score and its quality of life domain. Results 42 patients were included in the final analysis. Most patients (92.9%) received minimally invasive surgery for treating prostate cancer. During the follow up after 6 and 12 months, the daily pad, International Prostatic Symptom Score and its quality of life domain significantly improved compared to preoperative outcomes. The logistic regression analysis found that presence of comorbidities was the only predictive factor of low satisfaction rate (PGE-I > 2) in patients who underwent ProACT® implant. Conclusions ProACT® implant represents an effective and safe treatment for post-prostatectomy stress urinary incontinence with a high satisfaction degree and a low rate of complications.

Objectives To compare differences of operative outcomes, post-operative complications and survival outcomes between open and laparoscopic cases in a multicenter study. Methods This was a retrospective cohort study performed at three European centers from September 2011 to January 2019. The surgeon decision to perform open inguinal lymphadenectomy (OIL) or video endoscopic inguinal lymphadenectomy (VEIL) was done in each hospital after patient counselling. Inclusion criteria regarded a minimum follow-up of 9 months since the inguinal lymphadenectomy. Results A total of 55 patients with proven squamous cell penile cancer underwent inguinal lymphadenectomy. 26 of them underwent OIL, while 29 patients underwent VEIL. For the OIL and VEIL groups, the mean operative time was 2.5 vs. 3.4 h (p=0.129), respectively. Hospital stays were lower in the VEIL group with 4 vs. 8 days in OIL patients (p=0.053) while number of days requiring drains to remain in situ was 3 vs. 6 days (p=0.024). The VEIL group reported a lower incidence of major complications compared to the OIL group (2 vs. 17%, p=0.0067) while minor complications were comparable in both groups. In a median follow-up period of 60 months, the overall survival was 65.5 and 84.6% in OIL and VEIL groups, respectively (p=0.105). Conclusions VEIL is comparable to OIL regarding safety, overall survival and post-operative outcomes.

Introduction: The aim of the study was to provide data related to endoscopic combined intra-renal surgery learning curve using minimally invasive techniques with vacuum-assisted devices. Minimal data exist on the learning curve for these techniques. Methods: We conducted a prospective study monitoring the training of a mentored surgeon learning ECIRS with vacuum assistance. We use varied parameters for improvements. After collection of peri-operative data, tendency lines and CUSUM analysis were used to investigate the learning curves. Results: 111 patients have been included. Guy’s Stone Score 3 and 4 stones 51.3% of all cases. The mostly used percutaneous sheath was 16 Fr (87.3%). SFR was 78.4%. 52.3% patients were tubeless, and 38.7% achieved trifecta. High-degree complication rate was 3.6%. Operative time improved after 72 cases. We observed a decrease of complications throughout the case series, with improvement after 17 cases. In terms of trifecta, proficiency was reached after 53 cases. Proficiency seems achievable in a limited number of procedures, but results did not plateau. Higher number of cases might be necessary for excellence. Discussion: A surgeon learning ECIRS with vacuum assistance can obtain proficiency in 17–50 cases. The number of procedures required for excellence remains unclear. Exclusion of more complex cases might positively affect the training, reducing unnecessary complications.

Objectives The Rotterdam Prostate Cancer Risk calculator (RPCRC) has been validated in the past years. Recently a new version including multiparametric magnetic resonance imaging (mpMRI) data has been released. The aim of our study was to analyze the performance of the mpMRI RPCRC app. Methods A series of men undergoing prostate biopsies were enrolled in eleven Italian centers. Indications for prostate biopsy included: abnormal Prostate specific antigen levels (PSA>4 ng/ml), abnormal DRE and abnormal mpMRI. Patients’ characteristics were recorded. Prostate cancer (PCa) risk and high-grade PCa risk were assessed using the RPCRC app. The performance of the mpMRI RPCRC in the prediction of cancer and high-grade PCa was evaluated using receiver operator characteristics, calibration plots and decision curve analysis. Results Overall, 580 patients were enrolled: 404/580 (70%) presented PCa and out of them 224/404 (55%) presented high-grade PCa. In the prediction of cancer, the RC presented good discrimination (AUC = 0.74), poor calibration (p = 0.01) and a clinical net benefit in the range of probabilities between 50 and 90% for the prediction of PCa (Fig. 1). In the prediction of high-grade PCa, the RC presented good discrimination (AUC = 0.79), good calibration (p = 0.48) and a clinical net benefit in the range of probabilities between 20 and 80% (Fig. 1). Conclusions The Rotterdam prostate cancer risk App accurately predicts the risk of PCa and particularly high-grade cancer. The clinical net benefit is wide for high-grade cancer and therefore its implementation in clinical practice should be encouraged. Further studies should assess its definitive role in clinical practice.

Ablative techniques emerged as effective alternative to nephron-sparing surgery for treatment of small renal masses. Radiofrequency ablation (RFA) and cryoablation (CRYO) are the two guidelines-recommended techniques. Microwave ablation (MWA) represents a newer technology, less described. Aim of the study was to compare outcomes of MWA to those of CRYO and RFA.Retrospective investigation of patients who underwent MWA, CRYO, or RFA from seven high-volume US and European centers was performed. The first group included patients who underwent CRYO or RFA; the second MWA. We collected baseline characteristics, clinical, intraoperative and post-operative data. Oncological data included technical success, local recurrence, and progression to metastasis. Multivariate analysis was performed to find predictors for postoperative complications. A composite outcome of "trifecta" was used to assess surgical, functional, and oncological outcomes.739 patients underwent CRYO or RFA and 50 MWA. CRYO/RFA group had significantly longer operative time (p.001), but no difference in LOS, post-procedural Hb mean, intra-procedural complications (p=0.180), overall post-procedural complication rates (p=0.126), and in the 30-day re-admission rate (p=0.853) were detected. No predictive parameter of postprocedural complications was found. Concerning functional outcome no differences were detected in terms of eGFR at 1yr (p=0.182), ΔeGFR at 1-yr (p= 0.825) and eGFR at latest follow-up (p=0.070). "Technical success" was achieved in 98.6% of the cases (MWA= 100%, CRYO/RFA= 98.5%; p=0.775), and there was no significant difference in terms of 2-yr recurrence rate (p= 0.114) and metastatic progression (p= 0.203). Trifecta was achieved in 73.0% of CRYO/RFA vs 69.6% of MWA cases (p = 0.719).MWA is a safe and effective treatment option for small renal masses. Compared with CRYO/RFA, it seems to offer low complication rates, shorter operation time, and equivalent surgical and functional outcomes.

This cross-sectional study aimed to investigate the prevalence and clinical characteristics of erectile dysfunction in patients with obstructive sleep apnoea. We enrolled 133 male patients with suspected obstructive sleep apnoea. Ear, nose and throat evaluation, laboratory tests, body mass index, Epworth sleepiness scale, 5-international index of erectile function, overnight ambulatory polygraphy and drug-induced sleep endoscopy patterns were assessed. Eighty patients reported obstructive sleep apnoea. 60% (n=48) reported erectile dysfunction. Statistically significant correlations were found between 5-International Index of Erectile Function and age, hypertension, diabetes, Epworth sleepiness scale, apnoea-hypopnea index score, O2 saturation-nadir, and oxygen desaturation index. Age, diabetes and O2 saturation-nadir were independent predictors of erectile function. Epworth sleepiness scale, apnoea-hypopnea index score, O2 saturation-nadir, oxygen desaturation index and albumin were higher compared to patients without erectile dysfunction. No statistically significant differences were reported for drug-induced sleep endoscopy patterns and erectile dysfunction. Patients with obstructive sleep apnoea were at significant risk of having erectile dysfunction. Males with obstructive sleep apnoea should be investigated for erectile dysfunction.

Background In literature, the reports of outcomes after percutaneous nephrolithotomies are rather heterogeneous. This may influence studies comparison, it may also render difficult to evaluate surgical adequacy, peri-operative morbidity and patient's quality of life between studies. For this reason, we propose to introduce PNL-Trifecta as composite measure to standardize data reporting outcomes after percutaneous nephrolithotomies. Methods We performed a prospective multicentric study on consecutive patients undergone PNL to treat renal stones between 2018 and 2020. Successful PNL-trifecta was considered achieved when procedures obtained the three following results: no residual fragments > 2mm at unenhanced CT scan at 3 months post-op, no complications (defined as Clavien-Dindo Score 0) and operation carried out without placing a nephrostomy tube (tubeless or totally tubeless). We compared results of standard versus mini-PNL and between stones of different complexity (evaluated with Guy's Stone Score and S.T.O.N.E. nephrolithometry Score). Univariate analysis was utilized to identify other factors influencing achievement of PNL-Trifecta. Results 245 patients fulfilled inclusion/exclusion criteria and have been enrolled in the study (median age: 56, IQR 48-57). The overall PNL-Trifecta achievement rate was 22.85% (28.66% in the mini-PNL group and 13.68% in the standard-PNL group, p=0.010). The stone free rate, CD 0 rate and tubeless/totally tubeless rate in the mini-PNL group were 60.66%, 89.33% and 51.33% respectively. In the standard-PNL group they were 44.21%, 40.00% and 15.78% respectively. At the univariate analysis, differences between Guy's Stone Score groups in achieving PNL-Trifecta were significant (p=0.001). Also, the level of upper puncture (p=0.010) and utilization of device with active suction (p=0.002) showed statistically significant differences. Furthermore, the length of stay in the patient's group achieving Trifecta was 2.28 versus a mean length of stay of 4.64 days in the group of patients not achieving Trifecta (p=0.046). Conclusions We present Trifecta for PNLs as a potential tool to evaluate quality of percutaneous nephrolithotomies and to provide an instrument for an adequate standard data reporting. It can represent a valid way to assess and monitor surgeon's learning curves. It will require further external validation and studies to evaluate its correlation with mid- and long-term results and patient's health related quality of life outcomes.

Introduction: Double-J ureteral stents are subject to encrustation. Studies have shown that the encrustation onset is linked with indwelling time. In prevention, it is admitted that the Double-J stent indwelt for medium or long term should be replaced periodically. However, in the absence of guidelines, indwelling durations vary with centers' habits, stent indication, and stent materials. Our target was to evaluate the actual ureteral stent medium-/long-term indwelling times and related encrustation rates perceived by urologists in daily practice. Methods: An observational retrospective study was performed over six European centers. All data of all consecutive removed stents of the same material implanted for more than 2 months within a same 2-year referred period were collected. Three stent types of various materials, with/without coating, were evaluated. Encrustation rates were analyzed according to indwelling times and stent indication. Results: Four hundred seventy-three stents were recorded with indwelling times between 60 and 679 days. An unexpected number of long-term indwelling times were noticed: globally one-third more than 6 months, and 9% more than 1 year. In case of malignant indication, these rates were, respectively, 44% and 17%. For nonstone indication, clinically significant encrustation rates stayed extremely low before 4 months (1.3%) and quite low before 6 months (5.2%), increasing with time to reach around 10% in the long term. However, as expected, the rate was higher for stone indication with a marked increase after 4 months (8% before 4 months, nearly 17% after). Conclusion: Our data confirm a higher encrustation risk for stone patients. Long indwelling times in nonstone patients beyond 6 months or even 12 months appear to be still requested and relatively well supported in usual practice by this population.

BACKGROUND: The aim of the study was to test the effect of active surveillance (AS) versus primary intervention (PI) on overall mortality (OM) in elderly patients diagnosed with SRM. METHODS: Elderly patients (75 years or older) diagnosed with SRMs (

Rectal perforations during pelvic surgery are rare but serious complications. The occurrence of rectal involvement is generally lower than that of the involvement of other portions of the bowel. The urologic field is responsible for the majority of iatrogenic rectal injuries from pelvic surgery; general and gynecologic surgeries are prone to the occurrence as well, the latter especially in the case of rectal shaving for deep infiltrating endometriosis. Attention should be posed to the prevention of rectal injuries, especially in case of challenging or salvage procedures; some tricks may be recommended to avoid thermal and mechanical damages and to realize a safe dissection. Intraoperative detection of rectal injuries is of paramount importance; once confirmed, immediate management with the closure of the defect is recommended. In general, rectal injuries diagnosed after surgery are liable to significantly worse outcomes than those detected and managed intraoperatively.Rectal perforation is a rare but possible complication of pelvic surgeries. The more challenging the procedure (ie, surgery for locally advanced tumors or after radiation therapy), the higher the risk of rectal lesion. Intraoperative management of the injury should be attempted, with direct repair of the defect with or without fecal diversion.

Background: The impact of warm ischemia time (WIT) on renal functional recovery remains controversial. We examined the length of WIT >30 min. on the long-term renal function following on-clamp partial nephrectomy (PN). Methods: Data from 23 centers for patients undergoing on-clamp PN between 2000 and 2018 were analyzed. We included patients with two kidneys, single tumor, cT1, minimum 1-year followup, and preoperative eGFR ≥60 ml/min/1.73m2. Patients were divided into two groups according to WIT length: group Ⅰ "WIT ≤30 min." and group Ⅱ "WIT >30 min.". A propensity-score matched analysis (1:1 match) was performed to eliminate potential confounding factors between groups. We compared eGFR values, eGFR (%) preservation, eGFR decline, events of chronic kidney disease (CKD) upgrading, and CKD-free progression rates between both groups. Cox regression analysis evaluated WIT impact on upgrading of CKD stages. Results: The primary cohort consisted of 3526 patients: group Ⅰ (n=2868) and group Ⅱ (n=658). After matching the final cohort consisted of 344 patients in each group. At last followup, there were no significant differences in median eGFR values at 1, 3, 5, and 10 years (P>0.05) between the matched groups. In addition, the median eGFR (%) preservation and absolute eGFR change were similar (89% in group Ⅰ vs. 87% in group Ⅱ, p=0.638) and (-10 in group Ⅰ vs. -11 in group Ⅱ, p=0.577), respectively. The 5 years new-onset CKD-free progression rates were comparable in the non-matched groups (79% in group Ⅰ vs. 81% in group Ⅱ, log-rank, p=0.763) and the matched groups (78.8% in group Ⅰ vs. 76.3% in group Ⅱ, log-rank, p=0.905). Univariable Cox regression analysis showed that WIT >30 min. was not a predictor of overall CKD upgrading (HR:0.953, 95%CI 0.829-1.094, p=0.764) nor upgrading into CKD stage ≥Ⅲ (HR:0.972, 95%CI 0.805-1.173, p=0.764). Retrospective design is a limitation of our study. Conclusions: Our analysis based on a large multicenter international cohort study suggests that WIT length during PN has no effect on the long-term renal function outcomes in patients having two kidneys and preoperative eGFR ≥60 ml/min/1.73m2.

Urolithiasis is a worldwide spread condition that affects patients' Health-Related Quality of Life (HRQOL), which measurement is an important tool for routine clinical and research practice. Disease-specific HRQOL measures demonstrated to perform better in assessing the effects of specific conditions. A disease-specific questionnaire for kidney stones, the WISQOL, has been validated in different languages, but an Italian version is still missing. Our aim is to produce and validate the Italian version of WISQOL (IT-WISQOL). Patients undergoing any elective treatment for upper urinary tract stones were enrolled. A multi-step process with forward- and back-translation was used to translate WISQOL into Italian. Patients were evaluated within 15 days pre-operatively and then at 30-, 90 days post-operatively and administered both IT-WISQOL and SF-36v2. Post-operative data such as 30 days postoperative complications, late stone-related events, successful status, and stone complexity were collected. Cronbach's α was used to evaluate the internal consistency of IT-WISQOL, while Spearman's rho was used for item and inter-domain correlations and IT-WISQOL with SF-36v2 correlation. We found excellent internal consistency across all domains (α ≥ 0.88), particularly when the total score is considered (α = 0.960). Test-retest reliability showed excellent results for the total questionnaire (Pearson correlation value: 0.85). The Inter-domain association ranged from 0.497 to 0.786. Convergent validity was confirmed by a good correlation with subdomains of the SF-36v2 measures. IT-WISQOL is a reliable tool to measure HRQOL in stone patients. It shows analog characteristics if compared to English WISQOL.

Introduction and objectives: To evaluate the impact of the Controlling Nutritional Status (CONUT) score on perioperative morbidity and oncological outcomes of bladder cancer (BC) patients treated with radical cystectomy (RC). Materials and methods: We retrospectively analyzed a multi-institutional cohort of 347 patients treated with RC for clinical-localized BC between 2005 and 2019. The CONUT-score was defined as an algorithm including serum albumin, total lymphocyte count, and cholesterol. Multivariable logistic regression analyses were performed to evaluate the ability of the CONUT-score to predict any-grade complications, major complications and 30 days readmission. Multivariable Cox' regression models were performed to evaluate the prognostic effect of the CONUT-score on recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS). Results: A cut-off value to discriminate between low and high CONUT-score was determined by calculating the receiver operating characteristic (ROC) curve. The area under the curve was 0.72 hence high CONUT-score was defined as ≥3 points. Overall, 112 (32.3%) patients had a high CONUT. At multivariable logistic regression analyses, high CONUT was associated with any-grade complications (OR 3.58, P = 0.001), major complications (OR 2.56, P = 0.003) and 30 days readmission (OR 2.39, P = 0.01). On multivariable Cox' regression analyses, high CONUT remained associated with worse RFS (HR 2.57, P < 0.001), OS (HR 2.37, P < 0.001) and CSS (HR 3.52, P < 0.001). Conclusions: Poor nutritional status measured by the CONUT-score is independently associated with a poorer postoperative course after RC and is predictive of worse RFS, OS, and CSS. This simple index could serve as a comprehensive personalized risk-stratification tool identifying patients who may benefit from an intensified regimen of supportive cares.

The Italian Radical Cystectomy Registry (Registro Italiano Cistectomie - RIC) aimed to analyse outcomes of a multicenter series of patients treated with radical cystectomy (RC) for bladder cancer.An observational, prospective, multicenter, cohort study was performed to collect data from RC and urinary diversion via open (ORC), laparoscopic (LRC), or robotic-assisted (RARC) techniques performed in 28 Italian Urological Departments. The enrolment was planned from January 2017 to June 2020 (goal: 1000 patients), with a total of 1425 patients included. Chi-square and t-tests were used for categorical and continuous variables. All tests were 2-sided, with a significance level set at p0.05.Overall median operative-time was longer in RARCs (390 minutes, IQR 335-465) than ORCs (250, 217-309) and LRCs (292, 228-350) (p0.001). Lymph node dissection (LND) was performed more frequently in RARCs (97.1%) and LRCs (93.5%) than ORCs (85.6%) (p0.001), with extended-LND performed 2-fold more frequently in RARCs (61.6%) (p0.001). The neobladder rate was significantly higher (more than one-half) in RARCs. The median estimated blood loss (EBL) rate was lower in RARCs (250 ml, 165-400) than LRCs (330, 200-600) and ORCs (400, 250-600) (p0.001), with intraoperative blood transfusion rates of 11.4%, 21.7% and 35.6%, respectively (p0.001). The conversion to open rate was slightly higher in RARCs (6.8%) than LRCs (4.3%). Intraoperative complications occurred in 1.3% of cases without statistically significant differences among the approaches.Data from the RIC confirmed the need to collect as much data as possible in a multicenter manner. RARCs proves to be feasible with perioperative complication rates that do not differ from the other approaches.

Intraoperative adverse events (iAEs) are surgical and anesthesiologic complications. Despite the availability of grading criteria, iAEs are infrequently reported in the surgical literature and in cases for which iAEs are reported, these events are described with significant heterogeneity.To develop Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration criteria to standardize the assessment, reporting, and grading of iAEs. The ultimate aim is to improve our understanding of the nature and frequency of iAEs and our ability to counsel patients regarding surgical procedures.The present study involved the following steps: (1) collecting criteria for assessing, reporting, and grading of iAEs via a comprehensive umbrella review; (2) collecting additional criteria via a survey of a panel of experienced surgeons (first round of a modified Delphi survey); (3) creating a comprehensive list of reporting criteria; (4) combining criteria acquired in the first two steps; and (5) establishing a consensus on clinical and quality assessment utility as determined in the second round of the Delphi survey.Panel inter-rater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α.The umbrella review led to nine common criteria for assessing, grading, and reporting iAEs, and review of iAE grading systems led to two additional criteria. In the first Delphi round, 35 surgeons responded and two criteria were added. In the second Delphi round, 13 common criteria met the threshold for final guideline inclusion. All 13 criteria achieved the consensus minimum of 70%, with agreement on the usefulness of the criteria for clinical and quality improvement ranging from 74% to 100%. The mean inter-rater agreement was 89.0% for clinical improvement and 88.6% for quality improvement.The ICARUS Global Collaboration criteria might aid in identifying important criteria when reporting iAEs, which will support all those involved in patient care and scientific publishing.We consulted a panel of experienced surgeons to develop a set of guidelines for academic surgeons to follow when publishing surgical studies. The surgeon panel proposed a list of 13 criteria that may improve global understanding of complications during specific procedures and thus improve the ability to counsel patients on surgical risk.

Background During the past two decades cryoablation (CA) has become a therapeutic option for the management of localized cT1 renal masses in comorbid patients. We analyzed the midterm functional and oncological outcomes of CA in the treatment of cT1 renal masses which were classified as high-complexity masses according to the PADUA system. Methods A total of 299 patients underwent percutaneous CA between November 2007 and December 2018 in 4 institutions for cT1N0M0 renal masses. All patients with highcomplexity (PADUA ≥ 10) renal tumors were included. Technical failure of CA was considered an exclusion criterion. Results Inclusion criteria were met by 45 patients. Median Charlson Comorbidity Index (CCI) was 6.0 (IQR: 5.0-7.0), median age was 74 years (IQR: 64.5-79.5). Seven Clavien 1 and 1 Clavien 2 procedure-related complications were reported. Median eGFR at baseline was 64.3ml/min (IQR: 52.0 - 82.3) while at the 1-year follow-up was 61.4 ml/min (IQR: 44.0-74.5). The median follow-up was 32 months (IQR: 13.25-47.5). Local recurrences were detected in 6 patients; 3 of them underwent re-cryoablation while the others started active surveillance. Median time to recurrence was 17.5 months (IQR: 7.8-27.3). Cancer-Specific Survival and Metastasis-Free Survival were 100%. Overall survival was 86.7%. Conclusions CA proved to be a valuable therapeutic option for the management of patients with cT1 high-complexity PADUA ≥ 10 renal tumors as it provides a low rate of procedural morbidity and good preservation of renal function. However, these results are counterbalanced by a recurrence rate that appears to be higher than those reported on surgically treated patients.
