Open, laparoscopic, and robotic techniques for partial nephrectomy for renal cell carcinoma: a comparison of outcomes based on "trifecta" and "pentafecta" criteria

Introduction. There is a dearth of literature comparing the three modalities of partial nephrectomy – open, laparoscopic, and robotic – based on two contemporary criteria, “trifecta” and “pentafecta”. This scarcity justifies the significance of this study.Objective. To conduct a comparative evaluation of the outcomes of the three methods of partial nephrectomy, assessed against the criteria of “trifecta” and “pentafecta”.Materials & Methods. The prospective study included 600 patients with renal cell cancer from 2018 to 2022. partial nephrectomy was performed using open (200 patients), laparoscopic (200 patients) and robotic (200 patients) techniques. Outcomes were assessed by “trifecta” (negative surgical margin; warm ischemia time ≤ 25 minutes or without ischemia; no ≥ Clavien-Dindo III grade postoperative complications within 3 months after surgery) and “pentafecta” (“trifecta”, ≥ 90% estimated glomerular filtration rate preservation and no chronic kidney disease stage upgrading 12 months after surgery).Results. The “trifecta” outcome was achieved in 82%, 89%, and 84% of cases, respectively, using open, laparoscopic, and robotic approaches. No significant differences in outcomes were found between these methods (p > 0.05), according to this criterion. The “pentafecta” outcome was achieved in 53%, 64%, and 66% of cases using the same three approaches, respectively. Significant differences in outcomes between the open approach and the minimally invasive techniques were observed (p < 0.05) based on this criterion. For tumors that were considered easier to resect (R.E.N.A.L. 4 – 6 score), the highest “pentafecta” rates were observed with laparoscopic and robotic procedures. For tumors with moderate complexity (R.E.N.A.L. 7 – 9 score), open surgery resulted in the poorest outcomes, which were significantly different from those of robotic partial nephrectomy (p < 0.05). The laparoscopic approach yielded the poorest results for the most complex tumors (R.E.N.A.L. 10 – 12 score).Conclusions. In general, all three methods of partial nephrectomy produce the same outcome according to the “trifecta”, but according to the “pentafecta” better results may be achieved using minimally invasive techniques (laparoscopic and robotic procedures). Robotic partial nephrectomy should be considered as the method of choice for high-scored R.E.N.A.L. and cT1 – cT2 tumours.

The initial experience of robot-assisted nephron-sparing surgery in patients with renal cell cancer

Purpose of the study: analysis of our experience in performing robotic-assisted nephron-sparing surgeries using the da robotic system. Material and Methods. The retrospective study included the first 37 consecutive patients who underwent robot-assisted partial nephrectomy from May 2020 to december 2022. Results. To assess the surgical outcomes in patients undergoing partial nephrectomy, three parameters associated with trifecta achievement were analyzed. The trifecta was assessed according to the standard criteria, whereas the quadfecta, which in addition to the trifecta included preservation of >90 % of the glomerular filtration rate (calculated according to Cockroft–Gault) in the postoperative period (3–7 days), did not assess the stage of chronic renal failure one year after surgery, thus probably demonstrating the high percentage of its achievement (54.1 %). A positive surgical margin was observed in 1 (2.7 %) patients. Warm ischemia time of more than 25 minutes was used in 8 patients (21.6 %). Complications in the postoperative period (Clavien–dindo II and higher) were observed in 1 (2.7 %) patient. Trifecta and quadfecta rates were 78.4 % and 54.1 %, respectively. To analyze the surgeons’ experience, 37 renal cell cancer patients were divided into two subgroups with first 20 and subsequent robotic partial nephrectomies. There were no differences in gender, age and calculated RENAL value between 2 subgroups. depending on the surgeons’ experience, statistically significant differences in the duration of surgery (p=0.035) and blood loss during surgery (p=0.007) were found. Conclusion. Considering the extensive experience of surgeons in the field of laparoscopic surgery for tumors of the renal parenchyma, the outcomes of robotic partial nephrectomies performed in 37 patients seem to be satisfactory and successful. The accumulated experience of surgeons after 20 robotic-assisted nephron-sparing surgeries makes it possible to significantly reduce surgery time and blood loss. The technique of robotic-assisted partial nephrectomy requires further improvements.

Intraoperative imaging techniques for robotic-assisted partial nephrectomy: where do we stand?

Robot-assisted partial nephrectomy is currently the gold standard treatment for localized selected cT1 and cT2 renal tumors. This narrative review aims to analyze the technologies employed in this procedure to increase the precision and accuracy of the surgeon, in order to obtain adequate oncological radicality, negative surgical margins, and good preservation of renal function. In this scenario, new technologies are developing, from three-dimensional reconstructions to artificial intelligence up to the new concept of metaverse.

Outcomes and Techniques of Robotic-Assisted Partial Nephrectomy (RAPN) for Renal Hilar Masses: A Comprehensive Systematic Review.

Background: Robot-assisted partial nephrectomy (RAPN) is increasingly being employed in the management of renal cell carcinoma (RCC) and it is expanding in the field of complex renal tumors. The aim of this systematic review was to consolidate and assess the results of RAPN when dealing with entirely central hilar masses and to examine the various methods used to address the surgical difficulties associated with them. Methods: A thorough literature search in September 2023 across various databases focused on RAPN for renal hilar masses, adhering to PRISMA guidelines. The primary goal was to evaluate RAPN's surgical and functional outcomes, with a secondary aim of examining different surgical techniques. Out of 1250 records, 13 full-text manuscripts were reviewed. Results: Evidence is growing in favor of RAPN for renal hilar masses. Despite a predominance of retrospective studies and a lack of long-term data, RAPN shows positive surgical outcomes and preserves renal function without compromising cancer treatment effectiveness. Innovative suturing and clamping methods are emerging in surgical management. Conclusions: RAPN is a promising technique for managing renal hilar masses in RCC, offering effective surgical outcomes and renal function preservation. The study highlights the need for more long-term data and prospective studies to further validate these findings.

Enhancing Efficacy and Safety in Laparoscopic Partial Nephrectomy for Localized Renal Tuberculosis: The Skirted Continuous Suture Technique.

BACKGROUND Limited research has been conducted on laparoscopic partial nephrectomy for kidney tuberculosis. This study aimed to evaluate the effectiveness of the skirted continuous suture technique in laparoscopic partial nephrectomy for localized renal tuberculosis. MATERIAL AND METHODS Five patients with kidney tuberculosis underwent standard retroperitoneal laparoscopic partial nephrectomy after computed tomography evaluation. The skirted continuous suture technique was utilized during the procedure. This retrospective study analyzed the outcomes of these patients who received treatment between January 2011 and December 2020 at Beijing Tsinghua Changgung Hospital and Eighth Medical Center of Chinese People's Liberation Army General Hospital. RESULTS The surgical success rate was 100%. Renal function was well preserved, with a decrease of glomerular filtration rate by 9.6±9.0 ml/min. Only 1 patient experienced postoperative urinous infiltration and lymphatic fistula, while the others did not have any surgical complications. Antituberculous therapy was continued postoperatively, and 1 patient had recurrence during follow-up. CONCLUSIONS The laparoscopic continuous suturing technique offers a reliable and straightforward method for extensively closing incision edges of the renal parenchyma in laparoscopic surgery. It contributes to the improved efficacy and safety of treating localized renal tuberculosis with exceptional application.

Novel original suture technique in partial nephrectomy: experimental evaluation of efficacy

Introduction. Nephron-sparing surgery for localised renal cell carcinoma has firmly entered the guideline base of all urological associations. One important aspect of this surgery is the management of the renal wound after partial nephrectomy. The abundance of haemostasis methods is not only the result of relentless search, but also the real lack of universal and effective technologies.Objective. To evaluate the effectiveness of various suture techniques in partial nephrectomy.Materials & methods. The suture techniques were studied on laboratory mature male rats weighing 280 – 350 g with bilateral partial nephrectomy. The groups were assessed: suture time and relative suture eruption rate as the ratio of the number of eruptions to the total number of ligatures tied, morphological appearance of the resection line on days 7 and 28.Results. In the continuous and novel suture groups, suture time and heat ischaemia time were comparable (p = 0.068). In the group of horizontal interrupted sutures, this indicator was significantly higher (p < 0.01). Optimization of the renorraphy technique using the novel original suture made it possible to reduce the incidence of eruption and hemorrhagic complications by 19.7% compared to the twist suture (p<0.05). The use of a novel experimental suture made it possible to speed up the suturing time by 38.5%, and to reduce the risks of morphologically confirmed acute renal injury by 58.0% compared with the classic suturing technique of renal parenchyma. This group showed mild inflammatory and necrotic changes along the suture line with resorption by the fourth week of follow-up.Conclusion. Thus, the novel surgical suture made it possible not only to overcome the problem of insufficient mechanical strength inherent in vertical sutures, to reduce the risk of thread eruption, tangential deformities, and ischemia, but also to provide an acceptable heat ischemia time. This contributed to minimal ischemic and inflammatory changes among the three study groups.

A Novel Partial Nephrectomy Technique Using Blunt Dissection, Clipping of Intrarenal Vessels, Followed by Closure Using a Fibrin Sealant and Sliding Clips

ABSTRACT Purpose: We describe a surgical technique for robotic-assisted partial nephrectomy, including 3 novel steps to facilitate resection and suturing. This approach minimizes positive surgical margins and the risk of postoperative bleeding. Materials and Methods: This article describes a retrospective study of a single-surgeon series, including 49 patients. The study approach includes descriptive analysis of the Intraoperative Adverse Incident Classification, analysis of postoperative complications using the Clavien-Dindo Classification, and description of pathological and oncological outcomes. Results: The median operative time was 221 minutes (IQR: 196-263), and the median ischemia time was 20 minutes (IQR: 12-24). Intraoperative Adverse Incident Classification Grade 1 complications occurred in 2 patients (4%). Conversion to open partial nephrectomy was necessary in 1 patient (2%). Postoperative complications were reported in 7 patients (14%). Of these, 3 patients (6%) experienced a Clavien-Dindo Classification Grade 2 complication, 2 patients (4%) experienced a Grade 3a complication, 1 patient (2%) experienced a Grade 3b complication, and 1 patient (2%) experienced a Grade 4a complication. Endovascular coiling and blood transfusion were necessary in 2 patients (4%), and 2 patients (4%) were readmitted. A positive surgical margin was reported in 1 patient (2%). Metastatic relapse occurred in 1 patient (2%) 535 days after surgery who did not have a positive surgical margin. Conclusions: Our novel 3 surgical steps during robotic-assisted partial nephrectomy allow an oncologically safe resection with a low risk of postoperative complications.

Intra-renal Arteries in Nephrectomy from a Historical Aspect, a Quest Originated by Medical Illustrations to Reach Modern Angiography.

The aim of the present paper is to contribute to the understanding of the history of the anatomical study of the intra-renal arteries. The vasculature and especially the intra-renal arteries of the kidneys are an intriguing field which was first studied through art and then perfected by medicine. Angiography and microsurgery have resulted in partial nephrectomy techniques for surviving kidneys with adequate functional results. Graves' categorization dating from 1954 opened the way for innovative approaches that have resulted in modern topographical anatomy. CONCLUSION: Our understanding of the anatomy of intra-renal arteries has played a significant role in surgical anatomy and internal medicine.

The application of internal suspension technique in retroperitoneal robot-assisted laparoscopic partial nephrectomy with a new robotic system KangDuo Surgical Robot-01: Initial experience

ObjectiveTo assess the feasibility of internal suspension technique in retroperitoneal robot-assisted laparoscopic partial nephrectomy (rRAPN) with a new robotic platform called KangDuo Surgical Robot-01 (KD-SR-01) system (Suzhou KangDuo Robot Co., Ltd., Suzhou, China) and discuss its surgical technique. MethodsA 44-year-old male patient was admitted with a 2.5 cm tumor on dorsolateral upper pole of the left kidney. The R.E.N.A.L. nephrometry score of this patient was 4x. This patient underwent rRAPN with KD-SR-01. The perinephric fat between the tumor and Gerota's fascia was preserved, which was used for internal suspension traction during tumor resection. Postoperative follow-up data were collected. ResultsThe surgery was successfully carried out with a duration of 127 min, in which the docking time was 6 min 25 s and console time was 60 min. The warm ischemia time was 19 min 53 s, and the estimated blood loss was 0 mL. The pathological histology showed a pathological tumor stage 1a clear cell renal cell carcinoma, with a negative surgical margin. The World Health Organization/International Society of Urological Pathology (WHO/ISUP) grade of this patient was Grade 2. No recurrence was observed during the 6-month follow-up. ConclusionInternal suspension in rRAPN is feasible and effective with use of the new robotic system KD-SR-01.

A new surgical technique for sutureless partial nephrectomy: renal sutureless device.

Several factors impact the preservation of renal function after partial nephrectomy. Warm ischemia time is the main modifiable surgical factor. Renorrhaphy represents the key of hemostasia, but it is associated with increase of warm ischemia time and complications. The aim of this study was to describe our initial surgical experience with a new surgical technique for sutureless partial nephrectomy, based on the application of our own developed renal-sutureless-device-RSD. Between 2020-2021, 10 patients diagnosed with renal cell carcinoma stage cT1a-b cN0M0 with an exophytic component were operated using renal-sutureless-device-RSD. Surgical technique of sutureless partial nephrectomy with renal-sutureless-device-RSD is described in a step-by-step fashion. Clinical data was collected in a dedicated database. Presurgical, intraoperative, postoperative variables, pathology and functional results were evaluated. Medians and ranges of values for selected variables were reported as descriptive statistics. Partial nephrectomy was carried out with the use of renal-sutureless-device-RSD without renorrhaphy in all cases (70%cT1a-30%cT1b). Median tumor size was 3.15 cm (IQR: 2.5-4.5). R.E.N.A.L Score had a range between 4a-10. Median surgical time was 97.5 minutes (IQR 75-105). Renal artery clamping was only required in 4 cases, with a median warm ischemia time of 12.5 minutes (IQR 10-15). No blood transfusion, intraoperative and postoperative complications were noted. Free-of-disease margin rate achieved was 90%. Median length of stay was 2 days (IQR 2-2). Laboratory data on hemoglobin and hematocrit levels, as well as renal function tests, remained stable after partial nephrectomy. Our initial experience suggests that a sutureless PN using the RSD device is feasible and safe. Further investigation is needed to determine the clinical benefit of this technique.

Green Tattoo Pre-Operative Renal Embolization for Robotic-Assisted and Laparoscopic Partial Nephrectomy: A Practical Proof of a New Technique.

(1) Background: Our aim is to describe a new mixed indocyanine-non-adhesive liquid embolic agent (Onyx-18) pre-operative renal embolization technique for assisted-robotic and laparoscopic partial nephrectomy with near-infra-red fluorescence imaging. (2) Methods: Thirteen patients with biopsy-proven renal tumors underwent pre-operative mixed indocyanine-ethylene vinyl alcohol (EVOH) embolization (Green-embo) between June 2021 and August 2022. All pre-operative embolizations were performed with a super selective stop-flow technique using a balloon microcatheter to deliver an indocyanine-EVOH mixture into tertiary order arterial branch feeders and the intra-lesional vascular supply. Efficacy (evaluated as complete embolization, correct tumor mapping on infra-red fluorescence imaging and clamp-off surgery) and safety (evaluated as complication rate and functional outcomes) were primary goals. Clinical and pathological data were also collected. (3) Results: Two male and eleven female patients (mean age 72 years) received pre-operative Green-embo. The median tumor size was 29 mm (range 15-50 mm). Histopathology identified renal cell carcinoma (RCC) in 9 of the 13 (69%) patients, oncocytoma in 3 of the 13 (23%) patients and sarcomatoid RCC in 1 of the 13 (8%) patients. Lesions were equally distributed between polar, meso-renal, endo- and exophytic locations. Complete embolization was achieved in all the procedures. A correct green mapping was identified during all infra-red fluorescence imaging. All patients were discharged on the second day after the surgery. The median blood loss was 145 cc (10-300 cc). No significant differences were observed in serum creatinine levels before and after the embolization procedures. (4) Conclusions: The Green-tattoo technique based on a mixed indocyanine-non-adhesive liquid embolic agent (Onyx-18) is a safe and effective pre-operative embolization technique. The main advantages are the excellent lesion mapping for fluorescence imaging, reduction in surgical time, and definitive, complete and immediate tumor devascularization based on the deep Onyx-18 penetration, leading to a very low intra-operative blood loss.

Complications of radical nephrectomy and partial nephrectomy: What are they? How can they be anticipated and managed?

Surgical techniques of radical and partial nephrectomy have changed over the last 20years. Indications for partial nephrectomy have widened and mini-invasive surgery (laparoscopy and robotic assistance) has become widely used. However, both still have a significant morbidity. The objective of this article is to review complications of renal surgery and their predictive factors and to offer algorithms of management. Recent literature regarding complications of radical and partial nephrectomy was queried using Pubmed engine search. The most relevant articles were analyzed and served as a basis for this work. The literature on complications of radical and partial nephrectomy has a low level of evidence. There are only retrospective series. The most frequent complications of radical nephrectomy occur during surgery in 5-10% of the cases: wound of the pedicle or of an adjacent organ. The management can often be conservative. Laparoscopy has a similar morbidity compare to the open approach but has greatly increased postoperative outcomes and comfort. Partial nephrectomy has a 20% complication rate. Many factors have an impact on the risk of complications (tumor size, inflammation of perirenal fat, access, surgeon experience, centre volume, comorbidities and age of the patient) and must be taken into consideration before advising partial nephrectomy. The two most feared complications of partial nephrectomy are bleeding (per- or postoperative, 10% of the cases) and urinary fistula (<5% of the cases). Robotic assistance is associated with a lower morbidity in many publications. Complications after partial and radical nephrectomy are quite frequent but have decreased with the improvement of surgical techniques. French urologists should maintain their interest in novel technologies and simplification of perioperative pathway to further improve patients' outcomes.

The application of internal traction technique in retroperitoneal robot-assisted partial nephrectomy for renal ventral tumors

BackgroundFor patients with prior intra-abdominal surgery or multiple arteries, the retroperitoneal robot-assisted partial nephrectomy (rRAPN) is a better choice. The renal ventral tumor poses an additional challenge due to poor tumor exposure. This study is determined to assess the feasibility of an internal traction technique (ITT) in rRAPN for the management of renal ventral tumors.MethodsFrom November 2019 to March 2021, a total of 28 patients with renal ventral tumor underwent rRAPN. All patients had prior abdominal surgery or multiple arteries. The ITT group (20 patients), which improved the tumor exposure by traction of the kidney with suture, was compared with the traditional technique group (8 patients) in terms of warm ischemia time, estimated blood loss and postoperative hospital stay, retroperitoneal drainage, R.E.N.A.L. score, and serum creatinine. Differences were considered significant when P < 0.05.ResultsAll rRAPN surgeries were successful without conversion to radical nephrectomy or open partial nephrectomy. The warm ischemia time was lower in the ITT group (17.10 min vs. 24.63 min; P < 0.05). Estimated blood loss in the traditional technique group was 324.88 ± 79.42 mL, and in the ITT group, it was 117.45±35.25 mL (P < 0.05). No significant differences with regard to postoperative hospital stay, retroperitoneal drainage, R.E.N.A.L. score, and serum creatinine were observed between both groups. Surgical margins were negative and no intraoperative complications occurred in all the patients. After 10 months of follow-up, no recurrence or metastasis occurred in all cases.ConclusionITT is a feasible, safe, and valid procedure in rRAPN for renal ventral tumors. Application of ITT improved the exposure and reduces warm ischemic time in comparison with the conventional procedure.

Nefrectomía parcial laparoscópica off-clamp tras la embolización del tumor en sala híbrida frente a nefrectomía parcial convencional: un análisis de pares emparejados por puntuación de propensión

ObjectiveOff-clamp laparoscopic partial nephrectomy in a hybrid operating room after superselective arterial embolization (hLPN) is a promising minimally invasive approach. In this study, we compared the perioperative surgical outcomes of this innovative technique with the conventional standard of care laparoscopic partial nephrectomy (cLPN) technique. Patients and methodsOverall, 86 and 127 patients treated with hLPN and cLPN, respectively, were included. These two techniques were compared in terms of surgical complications, estimated blood loss (EBL), operative time, length of stay (LOS), surgical margins, and Trifecta achievement rate (defined as warm ischemia duration <25min, negative surgical margins and absence of complications). A propensity score based on age, gender, BMI, preoperative eGFR and tumor size was used for a 1:1 matching of patients of each group. After matching, two groups of 67 patients with similar characteristics were obtained. ResultsConversion rate to open surgery, complications and EBL were similar in both groups. Conversely, operative time, LOS and Trifecta rates favored hLPN. The multivariate analysis showed that hLPN had a 70% higher chance of Trifecta achievement than cLPN in all age groups and for all tumor size across the study population. ConclusionCompared to a conventional approach, off-clamp laparoscopic partial nephrectomy in a hybrid room after superselective arterial embolization showed satisfying immediate surgical outcomes and reached a higher rate of Trifecta achievement. Mid and long-term functional and oncological results are needed to establish this minimally invasive surgical alternative.

Application and clinical efficacy of modified early unclamping technique in robot-assisted laparoscopic partial nephrectomy

ObjectiveTo investigate the clinical safety and efficacy of a modified early unclamping technique in robot-assisted laparoscopic partial nephrectomy (RAPN).MethodsThe clinical data of 38 patients with renal tumors who underwent the modified early unclamping technique in RAPN surgery admitted to the Department of Urology, the Third People's Hospital of Hangzhou and the First Affiliated Hospital of Nanchang University from January 2018 to April 2021 were retrospectively analyzed. The control group consisted of 78 patients with renal tumors who underwent standard clamping during the RAPN surgery completed by the same surgeon during the same period. The perioperative-related indicators and postoperative renal function recovery were analyzed and compared between the two groups.ResultsAll patients (n = 116) finished the RAPN successfully, and none were transferred to radical or open surgery in either group. The warm ischemia time in the modified early unclamping group was significantly lower than that in the standard clamping group (P < 0.001). After surgery, the renal function index at each time point in the modified early unclamping group was higher than that in the standard clamping group; renal function gradually returned to near preoperative levels after 3 months in both groups. Postoperative follow-up showed no tumor recurrence or metastasis.ConclusionThe application of a modified early unclamping technique in RAPN surgery is safe and feasible. Compared with standard clamping, modified early unclamping can significantly shorten the warm ischemia time of kidneys without increasing the volume of intraoperative blood loss and complications, which helps to protect the postoperative renal function of patients.

Analysis of surgical and histopathological results of robot-assisted partial nephrectomy with use of three or four robotic arms: an early series results.

ABSTRACTObjectives:The aim of this study was to evaluate whether criteria exist to guide election between the use the three- or four-arm technique in robotic partial nephrectomy (RPN) instead of just the surgeon’s preference.Material and Methods:We performed a retrospective review of 80 patients submitted to RPN from May 2016 to February 2020. The patients were divided into two groups of 40, the first submitted to the surgical procedure with use of three robotic arms and the second with four arms. The group division was performed independently of the complexity of the cases, age or gender of the patients and laterality of the renal lesions. Peri- and postoperative data were analyzed for comparison between the two groups.Results:Both techniques had similar oncological outcomes (positive tumor margins), renal function preservation (warm ischemia time) and hemorrhagic complications (estimated blood loss and renal artery pseudoaneurysm), with a small difference in the need for blood transfusion, favoring the technique with three arms.Conclusions:The two robotic partial nephrectomy techniques had similar oncological and postoperative outcomes, with minimal perioperative complications. The three-arm technique is safe and feasible regardless of the complexity and size of the tumor. Additionally, the use of the three-arm technique reduced surgery costs by US$ 413.00 per patient.

Endoluminal balloons provide a reversible alternative to clamping of the graft artery. The objective of this video was to show the safety and efficiency of this technique for robot-assisted partial nephrectomy on kidney graft. METHODS: 69-year-old patient, transplanted in 2012, with extensive cardiovascular history. Discovery on follow-up ultrasound of a 2.5x2.3 cm tumor, confirmed by CT scan. Decision of robot-assisted partial nephrectomy after the multidisciplinary consultation meeting. An endoluminal balloon was placed in the segmental artery vascularizing the tumor after ponction of the femoral artery in interventional radiology. The patient was then installed in a supine position in the operating room for robotic-assisted partial nephrectomy, with trocar positioning similar to pelvic robotic surgery (assistant on the left side of the patient, two assistant trocars in the left iliac fossa and between the optical trocar and arm #1). RESULTS: The operative time in interventional radiology was 25 minutes, performed under local anesthesia. The operative time of the partial nephrectomy was 45 min, with a 10 min occlusion of the segmental artery. Blood loss was 200 cc. The postoperative period was uneventful, with the patient being discharged on day 2 after surgery. The serum creatinine level at discharge was 80 micromol/L, and the 3-month level was similar. Histopathologic analysis confirmed the malignant nature of the tumor, with clear cell renal cell carcinoma classified as pT1a Nx MO, nucleolar grade 3 (WHO 2018), with negative margins. 2 additional patients were performed using this technique, with similar results. CONCLUSIONS: Selective and reversible endoluminal balloon occlusion of segmental arteries appears to be a safe and effective alternative in arterial clamping for robotic-assisted partial nephrectomies on kidney grafts. A larger cohort will allow us to confirm our hypothesis.
