RESUMO
INTRODUCTION: We assessed the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) in patients with high comorbidity burden. MATERIALS AND METHODS: Data from patients treated with HoLEP at our academic referral center from March 2017 to January 2021 were prospectively collected. Patients were divided according to their CCI (Charlson Comorbidity Index). Perioperative surgical data and 3-month functional outcomes were collected. RESULTS: Out of 305 patients included, 107 (35.1%) and 198 (64.9%) were classified as CCI ≥ 3 and < 3, respectively. The groups were comparable in terms of baseline prostate size, symptoms severity, post-void residue and Qmax. The amount of energy delivered during HoLEP (141.3 vs. 118.0 KJ, p=0.01) and lasing time (38 vs 31 minutes, p=0.01) were significantly higher in patients with CCI ≥ 3. However, median enucleation, morcellation and overall surgical time were comparable between the two groups (all p>0.05). Intraoperative complications rate (9.3% vs. 9.5%, p=0.77), median time to catheter removal and hospital stay were comparable between the two cohorts. Similarly, early (30 days) and delayed (>30 days) surgical complications rates were not significantly different between the two groups. At 3-month follow up, functional outcomes using validated questionnaires did not differ between the two groups (all p>0.05). CONCLUSIONS: HoLEP represents a safe and effective treatment option for BPH also in patients with high comorbidity burden.

PURPOSE: We sought to evaluate outcomes of lymph node dissection (LND) in patients with upper tract urothelial carcinoma. MATERIALS AND METHODS: We performed a multicenter retrospective analysis utilizing the ROBUUST (for RObotic surgery for Upper Tract Urothelial Cancer Study) registry for patients who did not undergo LND (pNx), LND with negative lymph nodes (pN0) and LND with positive nodes (pN+). Primary and secondary outcomes were overall survival (OS) and recurrence-free survival (RFS). Multivariable analyses evaluated predictors of outcomes and pathological node positivity. Kaplan-Meier analyses (KMAs) compared survival outcomes. RESULTS: A total of 877 patients were analyzed (LND performed in 358 [40.8%]/pN+ in 73 [8.3%]). Median nodes obtained were 10.2 for pN+ and 9.8 for pN0. Multivariable analyses noted increasing age (OR 1.1, p <0.001), pN+ (OR 3.1, p <0.001) and pathological stage pTis/3/4 (OR 3.4, p <0.001) as predictors for all-cause mortality. Clinical high-grade tumors (OR 11.74, p=0.015) and increasing tumor size (OR 1.14, p=0.001) were predictive for lymph node positivity. KMAs for pNx, pN0 and pN+ demonstrated 2-year OS of 80%, 86% and 42% (p <0.001) and 2-year RFS of 53%, 61% and 35% (p <0.001), respectively. KMAs comparing pNx, pN0 ≥10 nodes and pN0 <10 nodes showed no significant difference in 2-year OS (82% vs 85% vs 84%, p=0.6) but elicited significantly higher 2-year RFS in the pN0 ≥10 group (60% vs 74% vs 54%, p=0.043). CONCLUSIONS: LND during nephroureterectomy in patients with positive lymph nodes provides prognostic data, but is not associated with improved OS. LND yields ≥10 in patients with clinical node negative disease were associated with improved RFS. In high-grade and large tumors, lymphadenectomy should be considered.

PURPOSE: To investigate prevalence and predictors of renal function variation in a multicenter cohort treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). METHODS: Patients from 17 tertiary centers were included. Renal function variation was evaluated at postoperative day (POD)-1, 6 and 12 months. Timepoints differences were Δ1 = POD-1 eGFR - baseline eGFR; Δ2 = 6 months eGFR - POD-1 eGFR; Δ3 = 12 months eGFR - 6 months eGFR. We defined POD-1 acute kidney injury (AKI) as an increase in serum creatinine by ≥ 0.3 mg/dl or a 1.5 1.9-fold from baseline. Additionally, a cutoff of 60 ml/min in eGFR was considered to define renal function decline at 6 and 12 months. Logistic regression (LR) and linear mixed (LM) models were used to evaluate the association between clinical factors and eGFR decline and their interaction with follow-up. RESULTS: A total of 576 were included, of these 409(71.0%) and 403(70.0%) had an eGFR < 60 ml/min at 6 and 12 months, respectively, and 239(41.5%) developed POD-1 AKI. In multivariable LR analysis, age (Odds Ratio, OR 1.05, p < 0.001), male gender (OR 0.44, p = 0.003), POD-1 AKI (OR 2.88, p < 0.001) and preoperative eGFR < 60 ml/min (OR 7.58, p < 0.001) were predictors of renal function decline at 6 months. Age (OR 1.06, p < 0.001), coronary artery disease (OR 2.68, p = 0.007), POD-1 AKI (OR 1.83, p = 0.02), and preoperative eGFR < 60 ml/min (OR 7.80, p < 0.001) were predictors of renal function decline at 12 months. In LM models, age (p = 0.019), hydronephrosis (p < 0.001), POD-1 AKI (p < 0.001) and pT-stage (p = 0.001) influenced renal function variation (ß 9.2 ± 0.7, p < 0.001) during follow-up. CONCLUSION: Age, preoperative eGFR and POD-1 AKI are independent predictors of 6 and 12 months renal function decline after RNU for UTUC.

OBJECTIVE: To assess whether socio-economic disparities exist on access to care, treatment options and outcomes among patients with renal mass amenable of surgical treatment within the universal healthcare system. METHODS: Data of consecutive patients submitted to partial nephrectomy (PN) or radical nephrectomy (RN) at our Institution between 2017 and 2020 were retrospectively evaluated. Patients were grouped according to their income level (low, intermediate, and high) based on the Indicator of Equivalent Economic Situation national criterion. Survival analysis was performed. Cox regression models were employed to analyse the impact of socio-economic variables on survival outcomes. RESULTS: One thousand forty-two patients were included (841 PN and 201 RN). Patients at the lowest income level were found more likely symptomatic and with a higher pathological tumour stage in the RN cohort (p > 0.05). The guidelines adherence on surgical indication rate as well as the access to minimally invasive surgery did not differ according to patient's income level in both cohorts (p > 0.05). Survival curves were comparable among the groups. Cox regression analysis showed that none of the included socio-economic variables was associated with survival outcomes in our series. CONCLUSIONS: Universal healthcare system may increase the possibility to ensure egalitarian treatment modalities for patients with renal cancer.

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 <70% at 48 months of follow-up. CONCLUSIONS: Martini's nomogram is a valid tool for predicting the decline in renal function at 6 and 12 months after robot-assisted partial nephrectomy and laparoscopic partial nephrectomy, whereas it showed a lower performance at longer follow-up and in patients treated with open approach at all these time cutoffs.

PURPOSE: Intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) has an incidence of approximately 20%-50%. Studies to date have been composed of mixed treatment cohorts-open, laparoscopic and robotic. The objective of this study is to assess clinicopathological risk factors for intravesical recurrence after RNU for UTUC in a completely minimally invasive cohort. MATERIALS AND METHODS: We performed a multicenter, retrospective analysis of 485 patients with UTUC without prior or concurrent bladder cancer who underwent robotic or laparoscopic RNU. Patients were selected from an international cohort of 17 institutions across the United States, Europe and Asia. Univariate and multiple Cox regression models were used to identify risk factors for bladder recurrence. RESULTS: A total of 485 (396 robotic, 89 laparoscopic) patients were included in analysis. Overall, 110 (22.7%) of patients developed IVR. The average time to recurrence was 15.2 months (SD 15.5 months). Hypertension was a significant risk factor on multiple regression (HR 1.99, CI 1.06; 3.71, p=0.030). Diagnostic ureteroscopic biopsy incurred a 50% higher chance of developing IVR (HR 1.49, CI 1.00; 2.20, p=0.048). Treatment specific risk factors included positive surgical margins (HR 3.36, CI 1.36; 8.33, p=0.009) and transurethral resection for bladder cuff management (HR 2.73, CI 1.10; 6.76, p=0.031). CONCLUSIONS: IVR after minimally invasive RNU for UTUC is a relatively common event. Risk factors include a ureteroscopic biopsy, transurethral resection of the bladder cuff, and positive surgical margins. When possible, avoidance of transurethral resection of the bladder cuff and alternative strategies for obtaining biopsy tissue sample should be considered.

BACKGROUND: The aim of the study was to describe the surgical outcomes of a retrospective series of consecutive patients treated with laparoscopic and robotic approach for adrenal masses in two tertiary referral centers. METHODS: We retrospectively gathered data of 477 patients submitted to adrenalectomy performed at two Institutions from March 2008 to February 2018 by six highly experienced surgeons. We excluded from the analysis 43 patients that had an open approach for tumors or for anesthetic contraindications to minimally invasive surgery (MIS). Patients were selected for surgery after a radiologic and an endocrinology work up. Preoperative, perioperative and postoperative data were recorded. RESULTS: Overall, 477 patients were included in the study. The robotic and the laparoscopic group included 110 and 367 patients, respectively. The preoperative characteristics were similar in both groups except for ASA score with a median (IQR) of 3 and 2 in the robotic and in the laparoscopic group, respectively (p = 0.03). Tumor size of adrenal tumors treated robotically (4, IQR 2.6-6 cm) was significantly larger than those treated laparoscopically (3, IQR 2.3-4.1 cm) (p = 0.01). The intraoperative complication rates were similar between robotic and laparoscopic groups (6.3% and 6%, respectively). The postoperative complication rate was 5.4% for robotic group and similarly 3.5% for laparoscopic adrenalectomy strategy. We analyzed the tumor ≥ 6 cm, with 29 patients in the robotic group and 43 in the laparoscopic one, with an overall complication rate of 19.5%. At multivariable analyses tumor size (OR 1.287; CI 1.128-1.468; p < 0.001) was the only independent predictor of overall complication. CONCLUSION: Adrenal tumors can be safely treated either by robotic or laparoscopic strategy. MIS seems to be feasible also in larger adrenal masses (≥ 6 cm). Tumor size represents the only predictive factors for overall complication.

BACKGROUND: Aim of this study was to evaluate and compare perioperative outcomes of transperitoneal (TP) and retroperitoneal (TR) approaches in a multi-institutional cohort of minimally invasive partial nephrectomy (MI-PN). MATERIAL AND METHODS: All consecutive patients undergone MI-PN for clinical T1 renal tumors at 26 Italian centers (RECORd2 project) between 01/2013 and 12/2016 were evaluated, collecting the pre-, intra-, and postoperative data. The patients were then stratified according to the surgical approach, TP or RP. A 1:1 propensity score (PS) matching was performed to obtain homogeneous cohorts, considering the age, gender, baseline eGFR, surgical indication, clinical diameter, and PADUA score. RESULTS: 1669 patients treated with MI-PN were included in the study, 1256 and 413 undergoing TP and RP, respectively. After 1:1 PS matching according to the surgical access, 413 patients were selected from TP group to be compared with the 413 RP patients. Concerning intraoperative variables, no differences were found between the two groups in terms of surgical approach (lap/robot), extirpative technique (enucleation vs standard PN), hilar clamping, and ischemia time. Conversely, the TP group recorded a shorter median operative time in comparison with the RP group (115 vs 150 min), with a higher occurrence of intraoperative overall, 21 (5.0%) vs 9 (2.1%); p = 0.03, and surgical complications, 18 (4.3%) vs 7 (1.7%); p = 0.04. Concerning postoperative variables, the two groups resulted comparable in terms of complications, positive surgical margins and renal function, even if the RP group recorded a shorter median drainage duration and hospital length of stay (3 vs 2 for both variables), p < 0.0001. CONCLUSIONS: The results of this study suggest that both TP and RP are feasible approaches when performing MI-PN, irrespectively from tumor location or surgical complexity. Notwithstanding longer operative times, RP seems to have a slighter intraoperative complication rate with earlier postoperative recovery when compared with TP.

BACKGROUND: Aim of the study was to present the surgical techniques and the postoperative outcomes in women treated with robotic excision for deep endometriosis involving the urinary tract. MATERIALS AND METHODS: We retrospectively reviewed the prospectively recorded clinical data of women consecutively undergoing minimally invasive treatment for complex endometriosis involving urinary tract in our center between January 2012 and June 2018. All the patients received a preoperative multidisciplinary evaluation with the general surgeon, the gynecologist and the urologist due to the frequent concomitant involvement of bowel and genital system. Patients undergoing robotic surgery were treated with the Si or Xi da Vinci surgical system. RESULTS: A total of 74 consecutive patients were enrolled. Twenty-eight (37.8%) patients underwent conventional laparoscopy and 46 (62.2%) robotic surgery. Only patients treated with robotic approach were considered for the final analyses. Overall, 17 (36.9%) patients were treated with partial cystectomy, 13 (28.3%) with ureteral reimplantation, 10 (21.7%) patients were treated with ureteral lysis, 4 (8.7%) with removal of bladder endometrial node without opening the mucosa layer and 2 (4.3%) with ureteral end-to-end anastomosis. Concomitant involvement of bowel and genital system was registered in 14 (30.4%) and 32 (69.5%) patients, respectively. No conversions to laparotomy were recorded. Overall, 5 (10.9%) patients experienced postoperative complications, of which only one was a major complication (Clavien 3b). At a median follow-up of 31.3 (IQR 17.6-43.3) months, 4 (8.7%) patients experienced disease recurrence at the level of urinary tract. CONCLUSIONS: Robotic excision of urological endometriosis represents a safe and effective treatment option, since a limited rate of surgical complications was recorded even in cases of multi-organ disease.

OBJECTIVE: To identify meaningful predictors and to develop a nomogram of postoperative surgical complications in patients treated with partial nephrectomy (PN). PATIENTS AND METHODS: We prospectively evaluated 4308 consecutive patients who had surgical treatment for renal tumours, between 2013 and 2016, at 26 Italian urological centres (RECORd 2 project). A multivariable logistic regression for surgical complications was performed. A nomogram was created from the multivariable model. Internal validation processes were performed using bootstrapping with 1000 repetitions. RESULTS: Overall, 2584 patients who underwent PN were evaluated for the final analyses. The median (interquartile [IQR]) American Society of Anesthesiologists (ASA) score was 2 (2-3). In all, 72.4% of patients had clinical T1a (cT1a) stage tumours. The median (IQR) Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 7 (6-8). Overall, 34.3%, 27.7%, 38% of patients underwent open PN (OPN), laparoscopic PN (LPN), and robot-assisted PN (RAPN). Overall and major postoperative surgical complications were recorded in 10.2% and 2.5% of patients, respectively. At multivariable analysis, age, ASA score, cT2 vs cT1a stage, PADUA score, preoperative anaemia, OPN and LPN vs RAPN, were significant predictive factors of postoperative surgical complications. We used these variables to construct a nomogram for predicting the risk of postoperative surgical complications. At decision curve analysis, the nomogram led to superior outcomes for any decision associated with a threshold probability of >5%. CONCLUSION: Several clinical predictors have been associated with postoperative surgical complications after PN. We used this information to develop and internally validate a nomogram to predict such risk.

PURPOSE: To report a multi-institutional experience on robotic radical nephroureterectomy (RNU) and segmental ureterectomy (SU) for upper tract urothelial carcinoma (UTUC). METHODS: Data were prospectively collected from patients with non-metastatic UTUC undergoing robotic SU or RNU at three referral centers between 2015 and 2018. Transperitoneal, single-docking robotic RNU followed established principles. Bladder cuff excision (BCE) was performed with robotic or open approach. Techniques for SU included: ureteral resection and primary uretero-ureterostomy; partial pyelectomy and modified pyeloplasty; ureteral resection with BCE and direct- or psoas hitch-ureteroneocystostomy. We retrospectively evaluated the technical feasibility, and peri-operative and oncologic outcomes after robotic RNU/SU. RESULTS: 81 patients were included. No case required conversion to open surgery. Early major (Clavien-Dindo grade > 2) complications were reported in six (7.4%) patients (two after SU, four after RNU). Three patients experienced late major complications (one after SU, two after RNU). Median ΔeGFR at 3 months was - 1 ml/min/1.73 m2 after SU and - 15 ml/min/1.73 m2 after RNU. Positive surgical margins were recorded in five patients (one after SU, four after RNU). Median follow-up was 21 months and 22 months in the SU and RNU groups, respectively. Three (20%) patients had ipsilateral upper tract recurrence after SU, while five (7.5%) developed metastases after RNU. No case of port-site metastases or peritoneal carcinomatosis was reported. At last follow-up, 67 (82.7%) patients were alive without evidence of disease. CONCLUSION: Robotic SU and RNU are technically feasible and achieved promising peri-operative and oncologic outcomes in selected patients with non-metastatic UTUC.

PURPOSE: To review the currently available literature reporting the patterns of recurrence and their predictive factors after open radical cystectomy (RC) for bladder cancer. METHODS: A review of the literature was performed using the MEDLINE, Scopus and Web of Sciences databases from January 1997 to May 2017. The PRISMA guidelines were followed for the conduct of the study. RESULTS: Local recurrence rate ranges between 30 and 54%. Distant recurrence is not often standardized and is reported in up to 50% of cases. The overall 5-year recurrence-free survival rates from 58 to 81%. The mean follow-up of studies included in the analysis ranged from 18 to 350 months. Details on the most important demographic and epidemiological, clinical, histologic and pathologic predictors of recurrence after radical cystectomy are provided through an evidence-based approach. The impact of the extension of lymph node dissection on recurrence after RC is investigated. CONCLUSIONS: A correct prognostic assessment is essential for patients undergoing radical cystectomy for bladder cancer, thereby potentially improving their oncologic outcomes.

PURPOSE: The present study sought to provide reproducible and patient-oriented metrics to assess the rate of "successful" outcomes (Trifecta) following holmium laser enucleation of the prostate (HoLEP). Clinical and surgical predictors of failure to achieve Trifecta were investigated. MATERIALS AND METHODS: We queried our prospectively collected database of all patients treated with HoLEP between March 2017 and January 2021. Trifecta was defined as the contemporary presence of: (1) no postoperative complication within 3 months; (2) no urinary incontinence at 3-months follow-up; and (3) 3-month postoperative max flow-rate >15 mL/s. Cases were grouped according to Trifecta achievement. All surgical procedures were carried out by a single surgeon. Surgical experience was divided into two different eras according to the number of procedures conducted (surgical era). Multivariate logistic regression analysis was performed to assess predictors of Trifecta failure. RESULTS: Overall 305 patients were included. Of these, 192 patients (63.0%) achieved Trifecta. Preoperative patient-related features were comparable between the two groups, except for a higher post-void residual (PVR) in non-Trifecta patients (median 180 vs. 130 mL, p=0.003). A significant proportion of Trifecta patients (88.5%) were treated in the second surgical era and in 126 (65.6%) cases an en-bloc enucleation was performed. Multivariate analysis confirmed PVR ≥250 mL, first surgical era and standard three-lobes enucleation technique as independent predictors of Trifecta failure. CONCLUSIONS: In our experience the rate of "successful" HoLEP, defined according to our newly introduced Trifecta metric, was 63.0%. We demonstrated that surgical strategy together with rising experience and baseline PVR are key elements to forecast the outcomes.
RESUMO
INTRODUCTION: Oncologic implications of variant histology (VH) have been extensively studied in bladder cancer; however, further investigation is needed in upper tract urothelial carcinoma (UTUC). Our study aims to evaluate the impact of VH on oncological outcomes in UTUC patients treated with radical nephroureterectomy (RNU). METHODS: A retrospective analysis was performed on patients who underwent a robotic or laparoscopic RNU for UTUC using the ROBUUST database, a multi-institutional collaborative including 17 centers worldwide. Logistic regression was used to assess the effect of VH on urothelial recurrence (bladder, contralateral upper tract), metastasis, and survival following RNU. RESULTS: A total of 687 patients were included in this study. Median (IQR) age was 71 (64-78) years and 470 (68%) had organ confined disease. VH was present in 70 (10.2%) patients. In a median follow-up of 16 months, the incidence of urothelial recurrence, metastasis, and mortality was 26.8%, 15.3%, and 11.8%, respectively. VH was associated with increased risk of metastasis (HR 4.3, P <.0001) and death (HR 2.0, P =.046). In multivariable analysis, VH was noted to be an independent risk factor for metastasis (HR 1.8, P =.03) but not for urothelial recurrence (HR 0.99, P =.97) or death (HR 1.4, P =.2). CONCLUSION: Variant histology can be found in 10% of patients with UTUC and is an independent risk factor for metastasis following RNU. Overall survival rates and the risk of urothelial recurrence in the bladder or contralateral kidney are not affected by the presence of VH.

The angiotensin-converting enzyme 2 receptor (ACE2) appears to be widely expressed in cells in the testes, predominantly in spermatogonia, Sertoli cells, and Leydig cells, and its co-expression with transmembrane protease serine 2 (TMPRSS2) is essential for the entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this reason, the male reproductive system could be considered a potential target for SARS-CoV-2, as well as a possible reservoir of infection. However, to date, there is very little evidence about the presence of SARS-CoV-2 in semen and testicular samples. The aim of this paper was to review the current evidence regarding the impact of SARS-CoV-2 on male fertility and sexual health, with a particular focus on reproductive hormones, the presence of the virus in seminal fluid and testis, and its impact on fertility parameters. We found very limited evidence reporting the presence of SARS-CoV-2 in semen and testicular samples, and the impact of SARS-CoV-2 on reproductive hormones and fertility parameters is unclear. The quality of the examined studies was poor due to the small sample size and several selection biases, precluding definitive conclusions. Hence, future well-designed prospective studies are needed to assess the real impact of SARS-CoV-2 on male reproductive function.
RESUMO
Background: Robotic sacrocolpopexy (RSCP) is an established option for the treatment of apical, anterior, and proximal posterior compartment pelvic organ prolapses (POP). However, there is lack of evidence investigating how lower bowel tract symptoms (LBTS) may change after RSCP. Methods: Data from consecutive patients treated with RSCP for stage 3 or higher POP from 2012 to 2019 at a single tertiary referral center with at least 1 year of follow-up were prospectively collected and retrospectively analyzed. RSCP was performed following a standardized technique which always employed both anterior and posterior hand-shaped meshes. Outcomes were collected at follow-up and analyzed. LBTS were evaluated through the Wexner questionnaire. Results: Overall, 114 women underwent RSCP. Eleven were excluded for missing data, whereas 12 had insufficient follow-up. Thus, 91 (79.8%) patients were included in this cohort. Median follow-up was 42 [interquartile range (IQR), 19-62] months. Mean age was 65 ± 10 years. In our series, RSCP was mainly performed for anterior and apical/medium stage 3 POP (in 95.6% of patients). Anatomic success rate of RSCP was 97.8%, with 89 patients with POP stage 0-1 at 12-month follow-up. Two patients (2.2%) experienced POP recurrence and were treated with redo-SCP. No patient experienced clinically significant posterior vaginal wall prolapse after RSCP. When analyzing LBTS, there was no significant change in postoperative total Wexner's score as compared to the preoperative value (p > 0.05). However, the manual assistance subscore was statistically significantly lower within the first-year follow-up (p = 0.04), but it spontaneously improved during the follow-up (p = 0.12). Conclusion: RSCP with simultaneous placement of both anterior and posterior mesh is safe and successful to treat high-stage POP in carefully selected patients. Of note, LBTS appear unaffected by posterior mesh placement, supporting its routine use to prevent posterior POP recurrence. Larger prospective studies are needed to confirm our results.
RESUMO
BACKGROUND: Robot-assisted partial nephrectomy (RAPN) is increasingly adopted for the treatment of localized renal tumors; however, rates and predictors of significant renal function (RF) loss after RAPN are still poorly investigated, especially at a long-term evaluation. OBJECTIVE: To analyze the predictive factors and develop a clinical nomogram for predicting the likelihood of ultimate RF loss after RAPN. DESIGN, SETTING, AND PARTICIPANTS: We prospectively evaluated all patients treated with RAPN in a multicenter series (RECORd2 project). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Significant RF loss was defined as >25% reduction in estimated glomerular filtration rate (eGFR) from preoperative assessment at 48th month follow-up after surgery. Uni- and multivariable logistic regression analyses for RF loss were performed. The area under the receiving operator characteristic curve (AUC) was used to quantify predictive discrimination. A nomogram was created from the multivariable model. RESULTS AND LIMITATIONS: A total of 981 patients were included. The median age at surgery was 64.2 (interquartile range [IQR] 54.3-71.4) yr, and 62.4% of patients were male. The median Charlson Comorbidity Index (CCI) was 1 (IQR 0-2), 12.9% of patients suffered from diabetes mellitus, and 18.6% of patients showed peripheral vascular disease (PVD). The median Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 7 (IQR 7-9). Imperative indications to partial nephrectomy were present in 3.6% of patients. Significant RF loss at 48th month postoperative evaluation was registered in 108 (11%) patients. At multivariable analysis, age (p = 0.04), female gender (p < 0.0001), CCI (p < 0.0001), CCI (p < 0.0001), diabetes (p < 0.0001), PVD (p < 0.0001), eGFR (p = 0.02), imperative (p = 0.001) surgical indication, and PADUA score (p < 0.0001) were found to be predictors of RF loss. The developed nomogram including these variables showed an AUC of 0.816. CONCLUSIONS: We developed a clinical nomogram for the prediction of late RF loss after RAPN using preoperative and surgical variables from a large multicenter dataset. PATIENT SUMMARY: We developed a nomogram that could represent a clinical tool for early detection of patients at the highest risk of significant renal function impairment after robotic conservative surgery for renal tumors.

BACKGROUND: Postoperative renal function impairment represents a main limitation for delivering adjuvant chemotherapy after radical nephroureterectomy (RNU). OBJECTIVE: To create a model predicting renal function decline after minimally invasive RNU. DESIGN, SETTING, AND PARTICIPANTS: A total of 490 patients with nonmetastatic UTUC who underwent minimally invasive RNU were identified from a collaborative database including 17 institutions worldwide (February 2006 to March 2020). Renal function insufficiency for cisplatin-based regimen was defined as estimated glomerular filtration rate (eGFR) <50 ml/min/1.73 m2 at 3 mo after RNU. Patients with baseline eGFR >50 ml/min/1.73 m2 (n = 361) were geographically divided into a training set (n = 226) and an independent external validation set (n = 135) for further analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Using transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) guidelines, a nomogram to predict postoperative eGFR <50 ml/min/1.73 m2 was built based on the coefficients of the least absolute shrinkage and selection operation (LASSO) logistic regression. The discrimination, calibration, and clinical use of the nomogram were investigated. RESULTS AND LIMITATIONS: The model that incorporated age, body mass index, preoperative eGFR, and hydroureteronephrosis was developed with an area under the curve of 0.771, which was confirmed to be 0.773 in the external validation set. The calibration curve demonstrated good agreement. Besides, the model was converted into a risk score with a cutoff value of 0.583, and the difference between the low- and high-risk groups both in overall death risk (hazard ratio [HR]: 4.59, p < 0.001) and cancer-specific death risk (HR: 5.19, p < 0.001) was statistically significant. The limitation mainly lies in its retrospective design. CONCLUSIONS: A nomogram incorporating immediately available clinical variables can accurately predict renal insufficiency for cisplatin-based adjuvant chemotherapy after minimally invasive RNU and may serve as a tool facilitating patient selection. PATIENT SUMMARY: We have developed a model for the prediction of renal function loss after radical nephroureterectomy to facilitate patient selection for perioperative chemotherapy.
