RESUMO
BACKGROUND: Partial nephrectomy (PN) is generally preferred for localized renal masses due to strong functional outcomes. Accurate prediction of new baseline glomerular filtration rate (NBGFR) after PN may facilitate preoperative counseling because NBGFR may affect long-term survival, particularly for patients with preoperative chronic kidney disease. Methods for predicting parenchymal volume preservation, and by extension NBGFR, have been proposed, including those based on contact surface area (CSA) or direct measurement of tissue likely to be excised/devascularized during PN. We previously reported that presuming 89% of global GFR preservation (the median value saved from previous, independent analyses) is as accurate as the more subjective/labor-intensive CSA and direct measurement approaches. More recently, several promising complex/multivariable predictive algorithms have been published, which typically include tumor, patient, and surgical factors. In this study, we compare our conceptually simple approach (NBGFRPost-PN = 0.90 × GFRPre-PN) with these sophisticated algorithms, presuming that an even 90% of the global GFR is saved with each PN. PATIENTS AND METHODS: A total of 631 patients with bilateral kidneys who underwent PN at Cleveland Clinic (2012-2014) for localized renal masses with available preoperative/postoperative GFR were analyzed. NBGFR was defined as the final GFR 3-12 months post-PN. Predictive accuracies were assessed from correlation coefficients (r) and mean squared errors (MSE). RESULTS: Our conceptually simple approach based on uniform 90% functional preservation had equivalent r values when compared with complex, multivariable models, and had the lowest degree of error when predicting NBGFR post-PN. CONCLUSIONS: Our simple formula performs equally well as complex algorithms when predicting NBGFR after PN. Strong anchoring by preoperative GFR and minimal functional loss (≈ 10%) with the typical PN likely account for these observations. This formula is practical and can facilitate counseling about expected postoperative functional outcomes after PN.

INTRODUCTION: Wound related complications (WRC) are a significant source of morbidity in kidney transplant recipients, and may be mitigated by surgical approach. We hypothesize that the anterior rectus sheath approach (ARS) may decrease WRC and inpatient opiate use compared to the Gibson Approach (GA). METHODS: This double-blinded randomized controlled trial allocated kidney transplant recipients aged 18 or older, exclusive of other procedures, 1:1 to ARS or GA at a single hospital. The ARS involves a muscle-splitting paramedian approach to the iliopsoas fossa, compared to the muscle-cutting GA. Patients and data analysts were blinded to randomization. RESULTS: Seventy five patients were randomized to each group between August 27, 2019 and September 18, 2020 with a minimum 12 month follow-up. There was no difference in WRC between groups (p = .23). Nine (12%) and three patients (4%) experienced any WRC in the ARS and GA groups, respectively. Three and one Clavien IIIb complications occurred in the ARS and GA groups, respectively. In a multiple linear regression model, ARS was associated with decreased inpatient opioid use (ß = -58, 95% CI: -105 to -12, p = .016). CONCLUSIONS: The ARS did not provide a WRC benefit in kidney transplant recipients, but may be associated with decreased inpatient opioid use.

Coronavirus disease-19 has had a marked impact on the transplant population and processes of care for transplant centers and organ allocation. Several single-center studies have reported successful utilization of deceased donors with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests. Our aims were to characterize testing, organ utilization, and transplant outcomes with donor SARS-CoV-2 status in the United States. We used Scientific Registry of Transplant Recipients data from March 12, 2020 to August 31, 2021 including a custom file with SARS-CoV-2 testing data. There were 35 347 donor specimen SARS-CoV-2 tests, 77.5% upper respiratory samples, 94.6% polymerase chain reaction tests, and 1.2% SARS-CoV-2-positive tests. Donor age, gender, history of hypertension, and diabetes were similar by SARS-CoV-2 status, while positive SARS-CoV-2 donors were more likely African-American, Hispanic, and donors after cardiac death (p-values <.01). Recipient demographic characteristics were similar by donor SARS CoV-2 status. Adjusted donor kidney discard (odds ratio = 2.08, 95% confidence interval [CI] 1.66-2.61) was higher for SARS-CoV-2-positive donors while donor liver (odds ratio = 0.44, 95% CI 0.33-0.60) and heart recovery (odds ratio = 0.44, 95% CI 0.31-0.63) were significantly reduced. Overall post-transplant graft survival for kidney, liver, and heart recipients was comparable by donor SARS-CoV-2 status. Cumulatively, there has been significantly lower utilization of SARS-CoV-2 donors with no evidence of reduced recipient graft survival with variations in practice over time.

Emerging data support the safety of transplantation of extra-pulmonary organs from donors with SARS-CoV-2-detection. Our center offered kidney transplantation (KT) from deceased donors (DD) with SARS-CoV-2 with and without COVID-19 as a cause of death (CoV + COD and CoV+) to consenting candidates. No pre-emptive antiviral therapies were given. We retrospectively compared outcomes to contemporaneous DDKTs with negative SARS-CoV-2 testing (CoVneg). From February 1, 2021 to January 31, 2022, there were 220 adult KTs, including 115 (52%) from 35 CoV+ and 33 CoV + COD donors. Compared to CoVneg and CoV+, CoV + COD were more often DCD (100% vs. 40% and 46%, p < .01) with longer cold ischemia times (25.2 h vs. 22.9 h and 22.2 h, p = .02). At median follow-up of 5.7 months, recipients of CoV+, CoV + COD and CoVneg kidneys had similar rates of delayed graft function (10.3%, 21.8% and 21.9%, p = .16), rejection (5.1%, 0% and 8.5%, p = .07), graft failure (1.7%, 0% and 0%, p = .35), mortality (0.9%, 0% and 3.7%; p = .29), and COVID-19 diagnoses (13.6%, 7.1%, and 15.2%, p = .33). Though follow-up was shorter, CoV + COD was associated with lower but acceptable eGFR on multivariable analysis. KT from DDs at various stages of SARS-CoV-2 infection appears safe and successful. Extended follow-up is required to assess the impact of CoV + COD donors on longer term graft function.

PURPOSE: Single-port (SP) robotic-assisted simple prostatectomy (RASP) through the transvesical approach is a novel surgical option in the management of large prostatic glands. We present the first multi-institutional study to further assess the perioperative and postoperative outcomes of SP RASP. MATERIALS AND METHODS: From February 2019 to November 2021, 91 consecutive patients of 3 separate institutions underwent transvesical RASP using the da Vinci® SP robotic surgical system. Surgeries were performed by 3 experienced surgeons. Through a suprapubic incision and transvesical access, the SP robot is docked directly into the bladder, and the prostatic enucleation is performed. Prospective data collection, including baseline characteristics, perioperative and postoperative outcomes, was performed. The mean followup period was 4.6 months. RESULTS: The mean (SD) prostate volume was 156 (62) ml. The mean (SD) total operative time was 159 (45) minutes, and the median (IQR) estimated blood loss was 100 (50, 200) cc. The median (IQR) postoperative hospital stay was 21.0 (6.5, 26.0) hours; however, 42% of all patients were discharged the same day. The median (IQR) Foley catheter duration was 5 (5, 7) days. Only 3 patients (3%) developed Clavien grade 2 postoperative complications. At 9-month followup, the median (IQR) International Prostate Symptom Score and quality of life score were 4 (2, 5) and 0 (0, 1), respectively, with a mean (SD) maximum flow rate and post-void residual of 21 (17) ml/second and 40 (55) ml, respectively. CONCLUSIONS: In a multi-institutional setting, the SP RASP promotes a pain-free procedure, same-day discharge, short Foley catheter duration, low complication rate and quick recovery.

PURPOSE: To evaluate a conceptually simple model to predict new-baseline-glomerular-filtration-rate (NBGFR) after radical nephrectomy (RN) based on split-renal-function (SRF) and renal-functional-compensation (RFC), and to compare its predictive accuracy against a validated non-SRF-based model. RN should only be considered when the tumor has increased oncologic potential and/or when there is concern about perioperative morbidity with PN due to increased tumor complexity. In these circumstances, accurate prediction of NBGFR after RN can be important, with a threshold NBGFR > 45 ml/min/1.73m2 correlating with improved overall survival. METHODS: 236 RCC patients who underwent RN (2010-2012) with preoperative imaging (CT/MRI) and relevant functional data were included. NBGFR was defined as GFR 3-12 months post-RN. SRF was determined using semi-automated software that provides differential parenchymal-volume-analysis (PVA) from preoperative imaging. Our SRF-based model was: Predicted NBGFR = 1.24 (× Global GFRPre-RN) (× SRFContralateral), with 1.24 representing the mean RFC estimate from independent analyses. A non-SRF-based model was also assessed: Predicted NBGFR = 17 + preoperative GFR (× 0.65)-age (× 0.25) + 3 (if tumor > 7 cm)-2 (if diabetes). Alignment between predicted/observed NBGFR was assessed by comparing correlation coefficients and area-under-the-curve (AUC) analyses. RESULTS: The correlation-coefficients (r) were 0.87/0.72 for SRF-based/non-SRF-based models, respectively (p = 0.005). For prediction of NBGFR > 45 ml/min/1.73m2, the SRF-based/non-SRF-based models provided AUC of 0.94/0.87, respectively (p = 0.044). CONCLUSION: Previous non-SRF-based models to predict NBGFR post-RN are complex and omit two important parameters: SRF and RFC. Our proposed model prioritizes these parameters and provides a conceptually simple, accurate, and clinically implementable approach to predict NBGFR post-RN. SRF can be easily obtained using PVA software that is affordable, readily available (FUJIFILM-Medical-Systems), and more accurate than nuclear-renal-scans. The SRF-based model demonstrates greater predictive-accuracy than a non-SRF-based model, including the clinically-important predictive-threshold of NBGFR > 45 ml/min/1.73m2.

Transplantation of solid organs from donors with active SARS-CoV-2 infection has been advised against due to the possibility of disease transmission to the recipient. However, with the exception of lungs, conclusive data for productive infection of transplantable organs do not exist. While such data are awaited, the organ shortage continues to claim thousands of lives each year. In this setting, we put forth a strategy to transplant otherwise healthy extrapulmonary organs from SARS-CoV-2-infected donors. We transplanted 10 kidneys from five deceased donors with new detection of SARS-CoV-2 RNA during donor evaluation in early 2021. Kidney donor profile index ranged from 3% to 56%. All organs had been turned down by multiple other centers. Without clear signs or symptoms, the veracity of timing of SARS-CoV-2 infection could not be confirmed. With 8-16 weeks of follow-up, outcomes for all 10 patients and allografts have been excellent. All have been free of signs or symptoms of donor-derived SARS-CoV-2 infection. Our findings raise important questions about the nature of SARS-CoV-2 RNA detection in potential organ donors and suggest underutilization of exceptionally good extrapulmonary organs with low risk for disease transmission.

OBJECTIVES: To evaluate the utility of parenchymal volume analysis (PVA) for estimation of split renal function (SRF) in patients with renal masses. SRF is important for deciding about partial vs radical nephrectomy (PN/RN) and assessing risk for developing severe chronic kidney disease after surgery. For renal donors PVA is routinely used to estimate SRF, but the utility of PVA for the more complex renal mass population remains undefined. PATIENTS AND METHODS: All patients (n = 374) with renal tumours and a normal contralateral kidney managed with PN (2010-2018), with preoperative/postoperative nuclear renal scans (NRS) and cross-sectional imaging were analysed. Parenchymal volumes were measured by free-hand scripting or software analysis. Concordance between ipsilateral estimated glomerular filtration rate (eGFR) values based on SRF from NRS vs PVA were evaluated by Pearson correlation and Bland-Altman plots. Parallel analysis of all 155 patients managed with RN at our centre (2006-2016) with preoperative NRS and imaging was also performed. RESULTS: For PN, the median age and tumour size were 62 years and 3.4 cm, respectively. The median preoperative ipsilateral parenchymal volume and eGFR were 181 cm3 and 36.9 mL/min/1.73 m2 , respectively. Parenchymal volumes estimated by free-hand scripting vs software analyses correlated strongly (r = 0.98, P < 0.001). Preoperative ipsilateral eGFR based on SRF from PVA vs NRS also correlated strongly (r = 0.94, P < 0.001). Ipsilateral eGFR saved after PN correlated strongly with parenchymal volume preserved (all r >0.60); however, the correlation was much stronger when ipsilateral eGFRs were based on SRF from PVA rather than NRS (z-statistic = 3.15, P = 0.002). For RN patients, preoperative eGFR in the contralateral kidney based on SRF from PVA vs NRS also correlated strongly (r = 0.87, P < 0.001). CONCLUSION: PVA has utility for estimation of SRF in patients with renal masses, even though this population is older and more comorbid than renal donors and the tumour can complicate the analysis. PVA can be obtained by software analysis from preoperative cross-sectional imaging and thus readily incorporated into routine clinical practice.

OBJECTIVES: To describe a step-by-step technique for robot-assisted radical cystectomy (RARC) with pelvic lymph node dissection (PLND) performed using the da Vinci® SP™ surgical system (Intuitive Surgical Inc., Sunnyvale, CA, USA). PATIENTS AND METHODS: Four consecutive patients diagnosed with urothelial carcinoma of the bladder were counselled for RARC with PLND and ileal conduit urinary diversion performed using the da Vinci SP surgical system. A 3-cm midline incision was made 5-cm above the umbilicus. Dissection was performed to access the abdominal cavity. Insertion of the GelPOINT® advanced access platform (Applied Medical, Rancho Santa Margarita, CA, USA) with the SP Cannula was performed through the incision made. A 12-mm AirSeal® (SurgiQuest Inc., Milfort, CT, USA) port for the assistant was placed on the pre-marked stoma site, where an ileal conduit urinary diversion was desired. Demographics and perioperative outcomes were collected under Institutional Review Board approval (IRB 13-780). The surgeries were performed by reproducing the steps of the institutional approach for RARC performed with the multi-arm robotic platform. RESULTS: The surgeries were successfully completed. There was neither conversion to standard multi-arm robotic or open approaches nor the need for additional port placement. The mean (range) operative time was 454 (420-496) min. Blood loss averaged 312 mL. No transfusions were required and no intraoperative complications occurred. All patients had negative surgical margins. All patients were discharged on postoperative day 5. CONCLUSION: From our preliminary experience, RARC with PLND and ileal conduit urinary diversion is feasible and safe using the da Vinci SP surgical system. Further comparative studies with open and multi-arm robotic approaches are warranted.
RESUMO
OBJECTIVES: To describe the step-by-step techniques for robot-assisted ureteric reimplantation performed using the Vinci SP® surgical system (Intuitive Surgical, Sunnyvale, CA, USA), including different case scenarios with an educational purpose. MATERIALS AND METHODS: Three consecutive patients diagnosed with distal benign ureteric strictures were counselled for ureteric reimplantation and consented to undergo surgery performed using the da Vinci SP surgical system. Demographics and peri-operative outcomes were collected after institutional review board approval (IRB 13-780). Patients provided informed consent having received an explanation for the adoption of the novel platform. The first patient was a woman referred to our institution for a left distal ureteric stricture after total hysterectomy for uterine fibroids with ureteric injury. The second patient was a man with BPH and recurrent UTIs, who was diagnosed with a 1.5-cm bladder stone and a large bladder diverticulum compressing the left distal ureter. The third patient was a man diagnosed with bilateral uretero-enteric anastomoses stricture status after radical cystectomy with orthotopic ileal neobladder urinary diversion for bladder cancer. RESULTS: The procedures were successfully completed. An extra port through a separate skin incision for the bedside assistant was placed for the first two procedures. In such cases, this additional port was used electively from the start of the procedure and did not represent a change in the treatment plan. Moreover, the port wound was used to accommodate the drainage. The bilateral ureteric reimplantation, however, was completed according to a pure single-site approach (no extra ports were placed out of the GelSeal cap). The mean operating times were 165, 150 and 180 min, respectively. Blood loss was 50 mL in all cases. No intra-operative complications occurred. Patients were discharged on postoperative days 1, 1 and 2, respectively, with normal serum creatinine levels. Neither transfusions nor major complications occurred. CONCLUSION: Robot-assisted reconstructive surgery for benign distal ureteric strictures is feasible and safe using the da Vinci SP surgical system.

PURPOSE: The growth potential of low grade prostate cancer is unknown and yet it is potentially impactful for the practice of active surveillance. We evaluated the incidence, growth dynamics and clinical significance of changes in prostate lesions on serial transrectal ultrasound among a large cohort of men with prostate cancer managed by active surveillance. MATERIALS AND METHODS: This retrospective study included men with prostate cancer treated with active surveillance at UCSF (University of California-San Francisco) from 2000 to 2014 who underwent a minimum of 2 transrectal ultrasound studies. Study inclusion criteria were prostate specific antigen 20 ng/ml or less, clinical stage T2 or less and biopsy Gleason grade 3 + 4 or less. Progression end points included an increase in imaging stage, a 50% or greater increase in volume and an increase in the number of sites (sextants) with apparent lesions. The relationship between transrectal ultrasound progression and biopsy Gleason upgrade was assessed by univariate and multivariate logistic regression models. RESULTS: The 875 identified patients underwent a median of 5 transrectal ultrasound studies (IQR 3-8). Median followup was 49 months (IQR 27-81). Of the patients 345 (39%) progressed on serial transrectal ultrasound, including 51 by size, 265 by the number of lesion sites and 279 by stage. Median time to progression was 14 months. Transrectal ultrasound progression was independently associated with biopsy upgrade (OR 1.8, 95% CI 1.3-2.5, p <0.01). CONCLUSIONS: Local progression on transrectal ultrasound was associated with Gleason upgrade at biopsy. These results suggest that stable imaging findings on transrectal ultrasound may allow for increased intervals between biopsies among men on active surveillance. A prospective study is required to evaluate the usefulness of such a practice.

OBJECTIVE: To determine the rate of outpatient cases and identify predictors for same-day discharge (SDD) after single-port transvesical enucleation of the prostate (STEP). METHODS: Retrospective analysis of all consecutive STEP cases performed at a single center by 3 surgeons from February 2019 to October 2023. The cohort was categorized into SDD cases (<8 hours until discharge) and inpatient cases. Group comparisons were made and logistic regression was used to identify predictors of SDD. RESULTS: A total of 152 STEP cases were performed successfully without additional ports or conversions. Fifty-two patients were pre-planned admissions, leaving 100 planned outpatient cases, of which 86% were discharged on the same day (median length of stay of 4.7 hours). Comparing the groups, inpatient cases were older, had higher Charlson Comorbidity Index (CCI) scores, higher estimated blood loss (EBL) during surgery, and more intraoperative complications than SDD patients. Univariate logistic regression identified age and CCI as the predictors associated with SDD after STEP. Notably, there were no major postoperative complications or readmissions in either group. CONCLUSION: In our 4-year experience with STEP, lower age and CCI score were significant predictors of SDD. The comprehensive evaluation criteria for discharge foster a safe recovery at home, coupled with a 0% rate of major postoperative complications and readmissions. These findings underscore the safety and efficacy of STEP, guiding patient counseling and surgeon expectations.
RESUMO
OBJECTIVE: To characterize the surgical management, perioperative, and cancer-specific outcomes, and the influence of aggressive histologic variants (AHV) on operative management among patients with renal cell carcinoma (RCC) and inferior vena cava (IVC) thrombus. RCC with rhabdoid and/or sarcomatoid differentiation, which we defined as AHV, portends a worse prognosis. AHV can be associated with a desmoplastic reaction which may complicate resection. METHODS: We reviewed patients undergoing radical nephrectomy and IVC thrombectomy between 1990 and 2020. Comparative statistics were employed as appropriate. Survival analysis was performed according to the Kaplan-Meier method, and intergroup analysis performed with log-rank statistics. Multivariable cox proportional hazards regression was used to assess the effect of AHV, age, thrombus level, vena cavectomy, metastases, and medical comorbidities on recurrence and overall survival (OS). RESULTS: Ninety-four of 403 (23.3%) patients had AHV, including 43 (46%) rhabdoid, 39 (41%) sarcomatoid, and 12 (13%) with both. AHV were more likely to present with advanced disease; however, increased perioperative complications or decreased OS were not observed. Median (IQR) survival was 16.7 (4.8-47) months without AHV and 12.6 (4-29) months with AHV (P = .157). Sarcomatoid differentiation was independently associated with worse OS (HR = 2.016, CI 1.38-2.95, P <.001), whereas rhabdoid alone or with sarcomatoid demonstrated similar OS (P = 0.063). CONCLUSION: RCC and IVC thrombus with AHV are more likely to present with metastatic disease, and sarcomatoid differentiation is associated with a worse OS. Resection of tumors with and without AHV have similar perioperative complications, suggesting that surgery can be safely accomplished in patients with RCC and IVC thrombus with AHV.

OBJECTIVES: Pathologic re-review of transurethral resection of bladder tumor (TURBT) specimen is a common practice at our tertiary care center, but its impact on disease risk stratification remains unknown. We sought to determine how pathologic re-review of specimen initially read at an outside institution changed grade, clinical T (cT) stage, and AUA non-muscle-invasive bladder cancer (NMIBC) risk stratification. METHODS AND MATERIALS: The laboratory information system was searched for patients who underwent TURBT from 2021 to 2022, yielding 561 records. 173 patients met inclusion criteria: 113 with
RESUMO
OBJECTIVE: Limited data exist on the frequency with which clinical progression during neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) impacts eligibility for a vaginal-sparing surgical approach or on the utility of interim imaging assessment. We sought to evaluate the incidence of clinical upstaging following NAC that would render a patient ineligible for a vaginal-sparing cystectomy. METHODS: Eighty-nine female patients with non-metastatic MIBC treated with NAC and radical cystectomy (RC) (2012-2023) were retrospectively reviewed. Tumor location(s) was determined from transurethral resection of bladder tumor operative reports. Pre- and post-NAC clinical staging was determined from imaging. Outcomes of interest included clinical upstaging and upstaging to vaginal invasion after NAC. RESULTS: 75/89 patients had pre- and post-NAC imaging. Fifty-five had no change in clinical staging, 6 patients were upstaged (4 cT2âcT3, 2 cT3âcT4), and 14 patients were downstaged (13 cT3âcT2, 1 cT4âcT2). Of the 75 patients with pre- and post-NAC imaging, 39 had trigone tumors. Of these, 28 had no change in clinical staging, 2 were upstaged (1 cT2âcT3, 1 cT3âcT4) and 9 were downstaged (8 cT3âcT2, 1 cT4âcT2). Overall, 6/75 (8%) of patients demonstrated clinical upstaging after NAC. 2/39 (5%) of patients with trigone tumors clinically progressed after NAC and both had vaginal invasion (pT4) on final pathology. CONCLUSION: Although clinical upstaging after NAC was infrequent, 5% of patients with trigonal MIBC were rendered ineligible for vaginal-sparing cystectomy following NAC due to progression. Interim imaging assessment may identify non-responders and preserve eligibility for vaginal-sparing RC.
