Robotic kidney transplantation.

Kidney transplantation is the best treatment option for patients with end-stage renal disease owing to improved survival and quality of life compared with dialysis. The surgical approach to kidney transplantation has been somewhat stagnant in the past 50 years, with the open approach being the only available option. In this scenario, evidence of reduced surgery-related morbidity after the introduction of robotics into several surgical fields has induced surgeons to consider robot-assisted kidney transplantation (RAKT) as an alternative approach to these fragile and immunocompromised patients. Since 2014, when the RAKT technique was standardized thanks to the pioneering collaboration between the Vattikuti Urology Institute and the Medanta hospital (Vattikuti Urology Institute-Medanta), several centres worldwide implemented RAKT programmes, providing interesting results regarding the safety and feasibility of this procedure. However, RAKT is still considered an alternative procedure to be offered mainly in the living donor setting, owing to various possible drawbacks such as prolonged rewarming time, demanding learning curve, and difficulties in carrying out this procedure in challenging scenarios (such as patients with obesity, severe atherosclerosis of the iliac vessels, deceased donor setting, or paediatric recipients). Nevertheless, the refinement of robotic platforms through the implementation of novel technologies as well as the encouraging results from multicentre collaborations under the umbrella of the European Association of Urology Robotic Urology Section are currently expanding the boundaries of RAKT, making this surgical procedure a real alternative to the open approach.

Oncologic surveillance intensity after endoscopic treatment of upper tract urothelial carcinoma.

BACKGROUND: The optimal oncologic surveillance in patients with upper tract urothelial carcinoma (UTUC) elected for conservative treatment is still a matter of debate. METHODS: Patients elected for endoscopic treatment of UTUC were followed up according to EAU guidelines recommendations after treatment. Bladder cancer recurrence-free survival (BCa-RFS), UTUC recurrence-free survival (UTUC-RFS), radical nephroureterectomy-free survival (RNU-FS), and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. The crude risks of BCa and UTUC recurrences over time were estimated with the Locally Weighted Scatterplot Smoothing method. RESULTS: Overall, 54 and 55 patients had low- and high-risk diseases, respectively. Median follow-up was 46.9 (IQR: 28.7-68.7) and 36.9 (IQR: 19.8-60.1) months in low and high-risk patients, respectively. In low-risk patients, BCa recurrence risk was more than 20% at 24 months follow-up. At 60 months, time point after which cystoscopy and imaging should be interrupted, the risk of BCa recurrence and UTUC recurrence were 14% and 7%, respectively. In high-risk patients, the risk of BCa and UTUC recurrence at 36 months was approximately 40% and 10%, respectively. Conversely, at 60 months, the risk of bladder recurrence and UTUC recurrence was 28% and 8%, respectively. CONCLUSIONS: For low-risk patients, cystoscopy should be performed semi-annually until 24 months, while upper tract assessment should be obtained up to 60 months, as per current EAU guidelines recommendations. For high-risk patients, upper tract assessment should be intensified to semi-annually up to 36 months, then obtained yearly. Conversely, cystoscopy should be ideally performed semi-annually until 60 months and yearly thereafter.

Simultaneous Bilateral Video-Endoscopic Inguinal Lymphadenectomy for Penile Carcinoma: Surgical Setting, Feasibility, Safety, and Preliminary Oncological Outcomes.

INTRODUCTION: Inguinal lymph node dissection (ILND) plays an important role for both staging and treatment purposes in patients diagnosed with penile carcinoma (PeCa). Video-endoscopic inguinal lymphadenectomy (VEIL) has been introduced to reduce complications, and in those patients elected for bilateral ILND, a simultaneous bilateral VEIL (sB-VEIL) has also been proposed. This study aimed to investigate the feasibility, safety, and preliminary oncological outcomes of sB-VEIL compared to consecutive bilateral VEIL (cB-VEIL). MATERIAL AND METHODS: Clinical N0-2 patients diagnosed with PeCa and treated with cB-VEIL and sB-VEIL between 2015 and 2023 at our institution were included. Modified ILND was performed in cN0 patients, while cN+ patients underwent a radical approach. Intra- and postoperative complications, operative time, time of drainage maintenance, length of hospital stay and readmission within 90 days, as well as lymph node yield, were compared between the two groups. RESULTS: Overall, 30 patients were submitted to B-VEIL. Of these, 20 and 10 patients underwent cB-VEIL and sB-VEIL, respectively. Overall, 16 (80%) and 7 (70%) patients were submitted to radical ILND due to cN1-2 disease in the cB-VEIL and sB-VEIL groups, respectively. No statistically significant difference emerged in terms of median nodal yield (13.5 vs. 14, p = 0.7) and median positive LNs (p = 0.9). sD-VEIL was associated with a shorter operative time (170 vs. 240 min, p < 0.01). No statistically significant difference emerged in terms of intraoperative estimated blood loss, length of hospital stay, time to drainage tube removal, major complications, and hospital readmission in the cB-VEIL and sB-VEIL groups, respectively (all p > 0.05). CONCLUSIONS: Simultaneous bilateral VEIL is a feasible and safe technique in patients with PeCA, showing similar oncological results and shorter operative time compared to a consecutive bilateral approach. Patients with higher preoperative comorbidity burden or anesthesiological risk are those who may benefit the most from this technique.

Probe-based confocal laser endomicroscopy in diagnosis of diffuse cystic lung disease in Sjögren's syndrome.

Sjögren's syndrome is systemic autoimmune disease characterized by lymphocytic infiltration of various organs with wide frequency of pulmonary involvement. Diffuse cystic lung disease in Sjögren's syndrome is a rare condition and requires differential diagnosis with other cystic pathologies such as lymphangioleyomiomatosis or Langerhans cell histiocytosis. Probe-based confocal laser endomicroscopy (pCLE) is a method of in vivo investigation of airways and lung tissue on microscopic level during bronchoscopy. We used this method in diffuse cystic lung disease caused by Sjögren's syndrome. The pCLE image showed a large number of fluorescent cells presumably lymphocytes in bronchioles, dilated alveolar spaces with fluid and thin alveolar walls. We think that the presence of the bronchiolar cells pattern can be used to differentiate between the pulmonary manifestations of Sjögren's disease and other cystic lung diseases.

Combined Reporting of Surgical Quality and Cancer Control after Surgical Treatment for Penile Tumors with Inguinal Lymph Node Dissection: The Tetrafecta Achievement.

BACKGROUND: To optimize results reporting after penile cancer (PC) surgery, we proposed a Tetrafecta and assessed its ability to predict overall survival (OS) probabilities. METHODS: A purpose-built multicenter, multi-national database was queried for stage I-IIIB PC, requiring inguinal lymphadenectomy (ILND), from 2015 onwards. Kaplan-Meier (KM) method assessed differences in OS between patients achieving Tetrafecta or not. Univariable and multivariable regression analyses identified its predictors. RESULTS: A total of 154 patients were included in the analysis. The 45 patients (29%) that achieved the Tetrafecta were younger (59 vs. 62 years; p = 0.01) and presented with fewer comorbidities (ASA score ≥ 3: 0% vs. 24%; p < 0.001). Although indicated, ILND was omitted in 8 cases (5%), while in 16, a modified template was properly used. Although median LNs yield was 17 (IQR: 11-27), 35% of the patients had <7 nodes retrieved from the groin. At Kaplan-Maier analysis, the Tetrafecta cohort displayed significantly higher OS probabilities (Log Rank = 0.01). Uni- and multivariable logistic regression analyses identified age as the only independent predictor of Tetrafecta achievement (OR: 0.97; 95%CI: 0.94-0.99; p = 0.04). CONCLUSIONS: Our Tetrafecta is the first combined outcome to comprehensively report results after PC surgery. It is widely applicable, based on standardized and reproducible variables and it predicts all-cause mortality.

Topical instillation of BCG immunotherapy for biopsy-proven primary upper urinary tract carcinoma in situ: A single institution series and systematic review.

Primary upper tract carcinoma in situ (UTcis) is a rare disease whose diagnosis and natural history are poorly understood. Radical nephroureterectomy is the standard of care but in imperatives or selected cases, topical instillations of Bacillus Calmette-Guérin (BCG) may represent a good alternative. The aim of this study was to report the histologic response to BCG instillations for the treatment of biopsy-proven UTcis and to systematically assess the current evidence on topical BCG instillation for the treatment of UTcis. This is a retrospective analysis of patients with biopsy-proven UTcis treated with BCG instillation between 1995 and 2020 in an expert center. The initial diagnosis was performed by a standardized random biopsy scheme during ureterorenoscopy (URS) in patients with positive cytology but negative CT and bladder biopsies. BCG course consisted of 6 weekly instillation of 81 mg Immucyst (Sanofi Pasteur MSD AG, Baar, Switzerland). Administration techniques were single-J, double-J and nephrostomy tube. The primary outcome was the rate of complete histological response at the 3-month 2nd-look-URS. Kaplan-Meier analysis curves assessed recurrence- and progression-free survival. A total of 22 patients (23 renal units) were included. Twenty-one (91.3%) patients completed the planned 6-week instillation cycle. Only one major complication was recorded (renal tuberculosis). Twenty patients had a 3-month 2nd-look-URS, with a complete histological response achieved in 17/20 cases (85%). After a median time of follow-up of 40 months (30-62), 8/20 patients harbored disease recurrence, including 5 cases of disease progression (≥pT2). The main limitations are the retrospective and non-comparative design of the study. Our systematic review (CRD42022324876) identified 15 studies (289 renal units). UTcis suffers from the lack of a standardized definition, and considerable heterogeneity has been found in making the diagnosis and assessing the response to treatment. Our study is the first to propose a histological diagnosis of UTcis as well as a histological re-evaluation of the response to treatment. Topical instillations of BCG appear to be a promising alternative, avoiding radical treatment in the majority of cases.

Energy source comparison in en-bloc resection of bladder tumors: subanalysis of a single-center prospective randomized study.

PURPOSE: Different energy sources are employed to perform en-bloc transurethral resection of bladder tumor (ERBT). No study compared different energy sources in ERBT. The aim is to compare the different ERBT sources in terms of pathological, surgical and postoperative outcomes. METHODS: This is a sub-analysis of a prospective randomized trial enrolling patients submitted to ERBT vs conventional TURBT from 03/2018 to 06/2021 (NCT04712201). 180 patients enrolled in ERBT group were randomized 1:1:1 to receive monopolar (m-ERBT), bipolar (b-ERBT) or thulium laser (l-ERBT). Endpoints were the comparison between energies in term of pathological analysis, intra, and post-operative outcomes. RESULTS: 49 (35%) m-ERBT, 45 (32.1%) b-ERBT, and 46 (32.9%) l-ERBT were included in final analysis. The rate of detrusor muscle (DM) presence was comparable between the energies used (p = 0.796) or the location of the lesion (p = 0.662). Five (10.2%), 10 (22.2%) and 0 cases of obturator nerve reflex (ONR) were recorded in m-ERBT, b-ERBT and I-ERBT groups, respectively (p = 0.001). Conversion to conventional TURBT was higher for lesions located in the anterior wall/dome/neck (p < 0.001), irrespective from the energy used. The presence of artifact in the pathological specimen was higher for lesions at the posterior wall (p = 0.03) and trigone (p = 0.03). CONCLUSIONS: In our study, no difference in staging feasibility among energies was found. Laser energy might be beneficial in lateral wall lesions to avoid ONR. Since there is an increased risk of ERBT conversion to conventional TURBT for lesions of the anterior wall, electrocautery might be preferred over laser to avoid waste of material.

Intracorporeal Versus Extracorporeal Robot-assisted Kidney Autotransplantation: Experience of the ERUS RAKT Working Group.

BACKGROUND: Kidney autotransplantation is a useful technique to be reserved for cases in which kidney function is compromised by a complex anatomical configuration, such as long ureteral strictures and renal vascular anomalies not suitable for in situ reconstruction. Robot-assisted kidney autotransplantation (RAKAT) presents a novel, minimally invasive, and highly accurate approach. OBJECTIVE: The aim of this study is to present the largest cohort of patients who underwent either extracorporeal (eRAKAT) or intracorporeal (iRAKAT) RAKAT, to confirm safety and feasibility and to compare the two approaches. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analyzed prospectively followed patients undergoing eRAKAT and totally intracorporeal RAKAT in a total of three institutions. SURGICAL PROCEDURE: Extracorporeal RAKAT and iRAKAT. MEASUREMENTS: Surgical and functional outcomes of patients subjected to eRAKAT and iRAKAT were measured. RESULTS AND LIMITATIONS: Between January 2017 and February 2021, 29 patients underwent RAKAT: 15 eRAKAT and 14 iRAKAT. No statistical difference in the preoperative data was recorded. The analysis of intraoperative variables showed a statistically significant difference between eRAKAT and iRAKAT in cold ischemia time (median [interquartile range {IQR}]: 151 [125-199] vs 27.5 [20-55]; p <  0.001) and total ischemia time (median [IQR]: 196.2 [182-241] vs 81.5 [73-88]; p <  0.001). However, faster renal function recovery in favor of eRAKAT was observed during the first 90 d, with comparable renal function at 1 yr. The 90-d Clavien-Dindo >2 complications were 13.8%. It is important to stress that RAKAT, and above all iRAKAT, should be performed by surgeons with experience in robotic renal, vascular, and transplant surgery. CONCLUSIONS: Both eRAKAT and iRAKAT represent promising minimally invasive techniques in selected cases with acceptable ischemia time and comparable long-term operative outcomes. PATIENT SUMMARY: In selected patients, both extra- and intracorporeal robot-assisted kidney autotransplantation represent valid alternatives in case of long ureteral strictures and renal vascular anomalies not suitable for in situ reconstruction.

Step-by-step Development of a Cold Ischemia Device for Open and Robotic-assisted Renal Transplantation.

BACKGROUND: Kidney transplantation (KT) is the best renal replacement treatment. The rewarming time is associated with ischemia/reperfusion damage. In both the open (open KT [OKT]) and the robotic (robotic-assisted KT [RAKT]) approaches, ice slush is used to maintain graft temperature (T°) below 20 °C. This may result in nonhomogeneous graft T° maintenance and, particularly during RAKT where the graft is completely inside the abdominal cavity, rises concerns regarding systemic hypothermia. OBJECTIVE: To design a cold ischemia device (CID) to maintain a constant and homogeneous low graft T° during surgery. DESIGN, SETTING, AND PARTICIPANTS: In IDEAL phase 0, a CID was developed and tested to determine its cooling effect on the kidney inside a closed system at 37.5 °C, by comparing it with kidney alone versus a gauze-jacket filled with ice slush. The CID was evaluated in pigs undergoing OKT and RAKT, assessing feasibility and adverse reactions. In IDEAL phase 1, the CID was tested in human OKT and RAKT. SURGICAL PROCEDURE: OKT and RAKT. MEASUREMENTS: In all phases, T° was evaluated at scheduled time points. RESULTS AND LIMITATIONS: In the preliminary tests of IDEAL phase 0, the CID was able to maintain a low graft T° and superiority to other groups (p = 0.002). In the in vivo animal model, the CID maintained a low and constant graft T° in OKT (n = 3) and RAKT (n = 3), with a mean T° at 50 min of 10.8 °C and 14.9 °C, respectively. IDEAL phase 1 demonstrated feasibility of both approaches (OKT, n = 2 and RAKT, n = 3) using the CID, and graft T° never exceeded 20 °C (mean T°: OKT 15.7 °C vs RAKT 18.3 °C). No complications were recorded. The main limitation consists in the low number of participants. CONCLUSIONS: The CID assured a constant low graft T° during rewarming time, in both OKT and RAKT. PATIENT SUMMARY: A cold ischemia device (CID) is the first step toward a feasible, safe, and reproducible method to maintain a low graft temperature during surgery. The employment of a CID may optimize the functional outcomes.

Thermovaccination - thermoheliox as a stimulator of the immune response. Kinetics of the synthesis of antibodies and C-reactive protein in coronavirus infection.

Clinical trials of thermoheliox application (inhalation with a high-temperature mixture of oxygen and helium, 90 °C) in the treatment of the acute phase of coronavirus infection were conducted. Dynamics of disease development in infected patients (PCR test for the virus) and, dynamics of changes in blood concentration of C-reactive protein, immunoglobulin M, specific immunoglobulin G were studied. High efficiency of thermoheliox in releasing the organism from the virus and stimulating the immune response (thermovaccination effect) was shown. The kinetic model of the process is proposed and analyzed.

Robotic radical cystectomy.

OBJECTIVES: Radical cystectomy (RC) is one of the most complex and morbid surgical procedures in Urology. Several retrospective and prospective studies have demonstrated that robotic-assisted RC (RARC) represents a minimally invasive alternative to open surgery, showing non-inferiority in mid-term oncological outcomes. Moreover, important advantages related with  perioperative complications have also been published. The aim of this article is to describe RARC surgical steps and to review the most relevant ndings in the eld of RARC, focusing on its strengths and weaknesses when compared with open RC. METHODS: We performed a detailed step-by-step description of the RARC surgical technique, paying particular attention to its specific surgical details and adding our tips and tricks for an out standing performance. We also conducted a review of the most relevant articles in literature in terms of oncological, pathological and perioperative results. All these findings have been compared with the classical open radical cystectomy (ORC) technique. RESULTS: None of the studies published have demonstrated RARC to have worse oncological outcomes (PSM,RFS, CSS, OS) compared to ORC. RARC shows a decrease in blood loss and transfusion rates. No differences have been observed in complications rate, length of hospital stay, quality of life, and time to bowel movement between both approaches. The two disadvantages of RARC compared to ORC are a longer operative time and increased cost. Operating time can be reduced with surgeons gaining experience and technique standardization. The cost disparities and operative time between ORC and RARC at high-volume academic centers are less pronounced than in the general medical community. CONCLUSIONS: RARC is a technically feasible and safe approach, with oncological, pathological and perioperative results, at least, equivalent to ORC.

Evaluation of the Spies TM modalities image quality

Introduction The Spies™ system (Karl-Storz®) was introduced into digital ureteroscopy to improve endoscopic vision. To date, there is no data to either indicate which of the Spies modalities is better for improving diagnosis and treatment procedures, nor to compare the modalities in terms of image quality. The aim of this study was to evaluate and compare the image quality of five Spies™ modalities (SM) to the standard white light in an in-vitro model. Materials and Methods Two standardized grids and 3 stones of different composition were recorded in white light and the 5SM (Clara, Chroma, Clara+Chroma), Spectra A and B) using 4 standardized aqueous scenarios. Twelve templates were done in order to simultaneously compare the same objective in the different modalities. Six urologists, five medical students, five urology residents, and five persons not involved with urology evaluated each video on a scale of 1 (very bad) to 5 (very good). Results Comparing white light to SM, subjects scored better the quality of Clara and Clara+Chroma than white light (p=0.0139 and p<0.05) and scored worse Spectra A and B (p=0.0005 and p=0.0023)). When comparing Clara to the other SM, it was ranked equivalent to Clara+Chroma (p=0.67) and obtained a higher rank than Chroma, Spectra A and B (p<0.05, p=0.0001 and p=0.0001). In the multivariate analysis mean scores were higher among urologists. Conclusion In all analyzed scenarios, the subjects ranked Clara and Clara+Chroma as the modalities with better image quality compared to white light.

[Laparoscopic management of ureteroileal stenosis: Long term follow up.] / Manejo laparoscópico de la estenosis uretero­ileal con seguimiento a largo plazo.

OBJECTIVE: To describe the laparoscopic approach for uretero-ileal anastomosis strictures and to analyse our long term series. METHODS: A retrospective review was performed evaluating our series of patients with benign ureteroileal anastomosis strictures treated laparoscopically from 2011 to 2017. Demographics and perioperative data were obtained and analyzed. Complications were described with the Clavien-Dindo classification. The surgical technique was described and a literature review was performed. RESULTS: Eleven procedures were performed in ten patients. Mean blood loss was 180 ml. All the operations were performed laparoscopically without conversion. Mean hospital stay was 10 days (4-23). Early complications were Clavien-Dindo I y II: Two cases of limited anastomosis leakage, one lymphorrea, one paralitic ileum and one accidental descent of the ureteral catheter. Mean follow-up was 56 months (12-179) No late complications have been described. CONCLUSION: Based on our series with 5 year follow up, the laparoscopic approach for uretero-ileal anastomosis strictures is feasible and safe.
