RESUMO

Off-clamp partial nephrectomy represents one of the latest developments in nephron-sparing surgery, with the goal of preserving renal function and reducing ischemia time. The aim of this study was to evaluate and compare the functional, oncologic, and perioperative outcomes between off-clamp robot-assisted partial nephrectomy (off-C RAPN) and off-clamp open partial nephrectomy (off-C OPN) through a propensity score-matched (PSM) analysis. A 1:1 PSM analysis was used to balance variables potentially affecting postoperative outcomes. To report surgical quality, 1 year trifecta was used. Univariable Cox regression analysis was performed to identify predictors of trifecta achievement. The Kaplan-Meier method was used to compare cancer-specific survival (CSS), overall survival (OS), disease-free survival (DFS), and metastasis-free survival (MFS) probabilities between groups. Overall, 542 patients were included. After PSM analysis, two homogeneous cohorts of 147 patients were obtained. The off-C RAPN cohort experienced shorter length of stay (LoS) (3.4 days vs. 5.4 days; p < 0.001), increased likelihoods of achieving 1 year trifecta (89.8% vs. 80.3%; p = 0.03), lower postoperative Clavien-Dindo ≤ 2 complications (1.3% vs. 18.3%, p < 0.001), and lower postoperative transfusion rates (3.4% vs. 12.2%, p = 0.008). At univariable analysis, the surgical approach (off-C RAPN vs. off-C OPN, OR 2.22, 95% CI 1.09-4.46, p = 0.02) was the only predictor of 1 year trifecta achievement. At Kaplan-Meier analysis, no differences were observed between the two groups in terms of OS (log-rank p = 0.451), CSS (log-rank p = 0.476), DFS (log-rank p = 0.678), and MFS (log-rank p = 0.226). Comparing RAPN and OPN in a purely off-clamp scenario, the minimally invasive approach proved to be a feasible and safe surgical approach, with a significantly lower LoS and minor rate of postoperative complications and transfusions as a result of improved surgical quality expressed by higher 1 year trifecta achievement.

RESUMO

Clear cell renal cell carcinoma (ccRCC) represents the most common subtype of renal tumor. Despite recent advances in identifying novel target molecules, the prognosis of patients with ccRCC continues to be poor, mainly due to the lack of sensitivity to chemo- and radiotherapy and because of one-third of renal cell carcinoma patients displays metastatic disease at diagnosis. Thus, identifying new molecules for early detection and for developing effective targeted therapies is mandatory. In this work, we focused on paraoxonase-2 (PON2), an intracellular membrane-bound enzyme ubiquitously expressed in human tissues, whose upregulation has been reported in a variety of malignancies, thus suggesting its possible role in cancer cell survival and proliferation. To investigate PON2 involvement in tumor cell metabolism, human ccRCC cell lines were transfected with plasmid vectors coding short harpin RNAs targeting PON2 transcript and the impact of PON2 silencing on cell viability, migration, and response to chemotherapeutic treatment was then explored. Our results showed that PON2 downregulation was able to trigger a decrease in proliferation and migration of ccRCC cells, as well as an enhancement of cell sensitivity to chemotherapy. Thus, taken together, data reported in this study suggest that the enzyme may represent an interesting therapeutic target for ccRCC.

RESUMO

Introduction: We aim to review the outcomes of shock wave lithotripsy (SWL), ureteroscopy, and percutaneous nephrolithotripsy (PCNL) for renal and ureteral stones in spinal cord neuropathy patients (SNP). Material and methods: A literature search was performed on 8th March 2023 using PubMed, EMBASE, and Google Scholar with no date limit. Preclinical/animal studies, reviews, letters to the editor, case reports, and meeting abstracts were excluded. Only English papers were accepted. Results: Thirty-five articles were accepted. Five studies focused on SWL, 17 on PCNL, and 6 on ureteroscopy. The remaining articles employed more than one procedure. Stone composition has shifted from struvite to the more common calcium phosphate. SWL showed a very poor stone-free rate (SFR) likely due to challenges in patient positioning, stone visualization, localization, and inability to pass fragments spontaneously. Flexible ureteroscopy and PCNL were associated with a high incidence of infectious complications, long hospital stays, high blood transfusion rate, and intensive care admissions. There were also cases of death. Both procedures were challenging due to genitourinary reconstruction, scoliosis and kyphosis, rib-cage deformity, lower limb contractures, and severe comorbidity which also affected anesthesia. SFR was lower than in non-neurological patients. Conclusions: SWL, ureterolithotripsy, and PCNL should be considered challenging procedures in SNP due to positioning issues, an increased risk of intra and peri-operative morbidity, and even mortality. Computed tomography should be recommended to assess residual fragments as it becomes imperative to minimize a re-intervention in SNP who should be preferably treated in referral centers.

RESUMO

OBJECTIVE: To assess if Alexis dual-ring wound protector/retractor reduced the incidence of superficial and deep incisional infection following open radical cystectomy (ORC). METHODS: Since January 2020, all procedures were performed using the Alexis retractor. We retrospectively reviewed our ORC database and compared patients who were operated on with Alexis with the same number of consecutive patients operated with a stainless steel retractor in the previous period. Data are presented as median and (interquartile range). RESULTS: Seventy-four patients underwent RC with Alexis (group 1) and 74 with stainless steel retractor (group 2). Median age was 73.0(13) in group 1, 73.5(14) in group 2 (P = .338). There were 59(79.7%) men in both groups. The groups were comparable in terms of comorbidities, body mass index, American Society of Anesthesiology score, and neoadjuvant chemotherapy rate. There was no statistically significant difference in type of lymph node dissection and urinary diversion, total surgical time. Postoperative stay was shorter in group 1 [8(4) days vs 9(4) in group 2, P = .012]. Group 2 had a significantly higher rate of both superficial (8.1% vs 18.9%, P = .045) and deep incisional infection (2.7% vs 14.9%, P = .009). At multivariable analysis, body mass index (OR 1.129 95% CI 1.162-1.283, P = .043) was significantly associated with higher odds of superficial incisional infection. The use of Alexis was significantly associated with lower odds of having both superficial (OR 0.274 95%CI 0.033-0.781, P = .023) and deep incisional infection (OR 0.159 95% CI 0.034-0.745, P = .020). CONCLUSION: The use of Alexis significantly reduces the rate of superficial and deep incisional infection following ORC.

RESUMO

Background: Patients who have undergone renal transplant may have a concomitant benign prostatic hyperplasia (BPH), a condition that can potentially hinder the recovery of the renal graft and necessitate surgical intervention. However, endoscopic treatment of BPH should be performed carefully because of the associated perioperative risks. We aimed to systematically assess the factors affecting surgical indications and perioperative outcomes of BPH surgical treatment in renal transplantation (RT) recipients. Methods: A systematic literature search was performed on January 28, 2023, using Scopus, PubMed, and EMBASE with no date limit. Preclinical and animal studies, reviews, letters to the editor, case reports, and meeting abstracts were excluded. Results: Eighteen articles were accepted and included. Clinical BPH has a high incidence rate after RT, particularly in elderly men. Secondary events associated with BPH, such as acute urinary retention and urinary tract infections, can lead to a gradual decline of renal graft function and patient survival. BPH procedure can prevent these events and guarantee improvements in serum creatinine levels, voiding parameters, and lower urinary tract symptoms. When the urine culture is negative, the endoscopic procedure of the prostate may be performed within 1 month of the initial procedure, particularly in older patients, more prone to develop voiding dysfunction. Alternatively, a transurethral incision of the prostate may be recommended for patients with smaller prostates who wish to preserve ejaculatory function. Data on comparative BPH surgical procedures are lacking. Conclusions: BPH procedure should be offered in RT recipients who develop bladder outlet obstruction owing to BPH. Endoscopic treatment should be performed after a few weeks from RT to avoid further graft deterioration.

RESUMO

Introduction: Megacalycosis is a rare disorder related to congenital underdevelopment of the renal papilla or structural defect of the renal calyces. Megacalycosis has a wide spectrum of clinical presentations ranging from simple variants without any significance on renal function to severe complications. Any prevention strategy is recommended yet since megacalycosis is mostly asymptomatic and usually discovered either accidentally or as result of its complications. Case presentation: We observed megacalycosis progression in a young female with a single kidney toward progressive calyx dilatation for years, which ended in acute pyelonephritis. Conservative management, urinary drainage, and large-spectrum antibiotics were unsuccessful and nephrectomy was required. Conclusion: This rare case and literature review add evidence to identify prognostic factors to select patients with a high risk of complications (single kidney, bilateral disease, female gender, associated genetic syndromes, vesicoureteral reflux, and contralateral renal disorder). One o more factors should activate close monitoring and prophylactic therapy if needed.

RESUMO

PURPOSE: False penile fractures (FPF) represent a rare sexual emergency characterized by blunt trauma of penis in the absence of albuginea's injury, with or without lesion of dorsal penile vein. Their presentation is often indistinguishable from true penile fractures (TPF). This overlapping of clinical presentation, and lack of knowledge about FPF, can lead surgeons often to proceed directly to surgical exploration without further examinations. The aim of this study was to define a typical presentation of false penile fractures (FPF) emergency, identifying in absence of "snap" sound, slow detumescence, penile shaft ecchymosis, and penile deviation main clinical signs. METHODS: We performed a systematic review and meta-analysis based on Medline, Scopus and Cochrane following a protocol designed a priori, to define sensitivity of "snap" sound absence, slow detumescence and penile deviation. RESULTS: Based on the literature search of 93 articles, 15 were included (73 patients). All patients referred pain, most of them during coitus (n = 57; 78%). Detumescence occurred in 37/73 (51%), and all patients described detumescence occurrence as "slow". The results show that single anamnestic item have a high-moderate sensibility in the diagnosis of FPF, and the highest sensitive item was penile deviation (sensibility = 0.86). However, when more than one item is present, overall sensitivity increases greatly, closing to 100% (95% Confidence Interval 92-100). CONCLUSION: Surgeons can consciously decide between additional exams, a conservative approach, and rapid intervention using these indicators to detect FPF. Our findings identified symptoms with excellent specificity for FPF diagnosis, giving clinicians more useful tools for making decisions.

RESUMO

Renal cell carcinoma (RCC) belongs to a heterogenous cancer group arising from renal tubular epithelial cells. Among RCC subtypes, clear cell renal cell carcinoma (ccRCC) is the most common variant, characterized by high aggressiveness, invasiveness and metastatic potential, features that lead to poor prognosis and high mortality rate. In addition, diagnosis of kidney cancer is incidental in the majority of cases, and this results in a late diagnosis, when the stage of the disease is advanced and the tumor has already metastasized. Furthermore, ccRCC treatment is complicated by its strong resistance to chemo- and radiotherapy. Therefore, there is active ongoing research focused on identifying novel biomarkers which could be useful for assessing a better prognosis, as well as new molecules which could be used for targeted therapy. In this light, several novel targeted therapies have been shown to be effective in prolonging the overall survival of ccRCC patients. Thus, the aim of this review is to analyze the actual state-of-the-art on ccRCC diagnosis, prognosis and therapeutic options, while also reporting the recent advances in novel biomarker discoveries, which could be exploited for a better prognosis or for targeted therapy.

RESUMO

Background and Objectives: Inguinal hernia (IH) is a usual finding in men with prostate cancer (PCa) due to their similar risk factors, such as age, gender, and smoking. This study aims to present a single institution's experience with simultaneous IH repair (IHR) and robotic-assisted radical prostatectomy (RARP). Materials and Methods: We retrospectively reviewed 452 patients who underwent RARP between January 2018 and December 2020. A total of 73 patients had a concomitant IHR with a monofilament polypropylene mesh. Patients with bowel in the hernia sac or recurrent hernia were excluded. Results: The median age and the American Society of Anesthesiologists (ASA) score were 67 years (inter-quartile range (IQR) 56-77) and 2 (IQR 1-3), respectively. The median prostate volume and preoperative prostate-specific antigen (PSA) were 38 mL (IQR 25.0-75.2) and 7.8 ng/mL (IQR 2.6-23.0), respectively. The surgery was successfully performed in all cases. The median overall and IHR operative time were 190.0 (IQR 140.0-230.0) and 32.5 (IQR 14.0-40.0) minutes, respectively. The median estimated blood loss and length of hospital stay were 100 mL (IQR 10-170) and 3 days (IQR 2-4), respectively. Only five (6.8%) minor complications occurred after surgery. At the 24-month follow-up, no cases of mesh infection, seroma formation, or groin pain were recorded. Conclusions: This study confirmed the safety and efficacy of performing simultaneous RARP and IHR.

RESUMO

OBJECTIVE: Prostate cancer with seminal vesicle invasion (SVI) has been considered an aggressive cancer. To evaluate the prognostic significance of different patterns of isolated SVI in patients undergoing radical prostatectomy (RP) and pelvic lymphadenectomy. METHODS AND MATERIALS: We retrospectively analyzed all patients who underwent RP between 2007 and 2019. Inclusion criteria were localized prostate adenocarcinoma, SVI at RP, at least 24-months follow-up, and no adjuvant treatment. Patterns of SVI were following Ohori's classification: type 1: direct spread along the ejaculatory duct from inside; type 2: seminal vesicle invasion outside the prostate, through the capsule; type 3: the presence of cancer island(s) in the seminal vesicle with no continuity from the primary tumor (discontinuous metastases). Patients with type 3 SVI (isolated or in association) were included in the same group. Biochemical recurrence (BCR) was defined as any postoperative PSA ≥0.2 ng/ml. A logistic regression analysis was performed to assess predictors of BCR. Time to BCR was investigated using the Kaplan-Meier analysis with the log-rank test. RESULTS: Sixty-one out of 1,356 patients were included. Median age was 67(7.2) years. Median PSA was 9.4(8.92) ng/ml. Mean follow-up was 85.28 ± 45.27 months. BCR occurred in 28(45.9%) patients. Logistic regression showed that a positive surgical margin (OR 19.964, 95%CI:1.172-29.322, P = 0.038) was predictor of BCR. Kaplan-Meier analysis demonstrated that patients with pattern 3 had a significantly shorter time to BCR compared to other groups (log-rank, P = 0.016). The estimated time to BCR was 48.7 months in type 3, 60.9 months in pattern 1 + 2, 74.8, and 100.8 months in isolated patterns 1 and 2, respectively. In patients with negative surgical margins, pattern 3 confirmed a shorter time to BCR compared to other types of invasions, with an estimated time to BCR of 30.8 months. CONCLUSIONS: Patients with type 3 SVI demonstrated a shorter time to BCR compared to other patterns.

RESUMO

Lead (Pb) is a metal with a widespread diffusion in the environment. Pb tends to accumulate in the human body and, as a consequence, semen alterations can be present in exposed workers or general population. The aim of the present study is to evaluate the effect on semen parameters among healthy men exposed to environmental or occupational Pb. A systematic literature search was performed on November 12th, 2022, through MEDLINE via PubMed, Scopus, and Embase. Observational studies comparing semen parameters in men exposed to Pb and those not exposed were included. Sperm parameters were pooled using the Cochran-Mantel-Haenszel Method with a random effect model. The weighted mean difference (WMD) was used as a summary measure. Statistical significance was set at p-value 0.05. Ten papers were included. Pb exposure was associated with a significant reduction in semen volume (WMD -0.76 ml.95% CI -1.47, -0.05, p = 0.04), sperm concentration (WMD -0.63 ×106/ml 95% CI -1.15, -0.12, p = 0.02), total sperm count (WMD -1.94 ×106 95% CI -3. 77, -0.11, p = 0.04), sperm vitality (WMD -2.18% 95% CI -3.92, -0.45, p = 0.01), and total sperm motility (WMD -1.31% 95% CI -2.33, -0.30, p = 0.01). No difference was found in sperm normal morphology, progressive motility, and seminal viscosity. This review demonstrated the negative effect of Pb exposure on most of semen parameters. Given the diffuse exposure to this metal of the general population, public health concerns should be considered and exposed workers should be assessed to evaluate their semen.

RESUMO

PURPOSE: To evaluate outcomes of flexible ureteroscopy for renal stones by comparing hard versus soft stones based on their attenuation on computed tomography (Hounsfield Units-HU). METHODS: Patients were divided into two groups according to the type of laser employed [Holmium:YAG (HL) or Thulium fiber laser (TFL)]. Residual fragments (RF) were defined as > 2 mm. Multivariable logistic regression analysis was performed to evaluate factors associated with RF and RF needing further intervention. RESULTS: 4208 patients from 20 centers were included. In whole series, age, recurrent stones, stone size, lower pole stones (LPS), and multiple stones were predictors of RF at multivariable analysis and LPS and stone size with RF requiring further treatment. HU and TFL were associated with lesser RF and RF requiring an additional treatment. In HU < 1000 stones, recurrent stones, stone size, and LPS were predictors of RF at multivariable analysis, whereas TFL was less likely associated with RF. Recurrent stones, stone size, and multiple stones were predictors of RF requiring further treatment, while LPS and TFL were associated with lesser RF requiring further treatment. In HU ≥ 1000 stones, age, stone size, multiple stones, and LPS were predictors of RF at multivariable analysis, while TFL was less likely associated with RF. Stone size and LPS were predictors of RF requiring further treatment, whereas TFL was associated with RF requiring further treatment. CONCLUSION: Stone size, LPS, and use of HL are predictors of RF after RIRS for intrarenal stones regardless of stone density. HU should be considered an important parameter in predicting SFR.

RESUMO

PURPOSE OF REVIEW: Kidney puncture is a key step in percutaneous nephrolithotomy (PCNL). Ultrasound/fluoroscopic-guided access to the collecting systems is commonly used in PCNL. Performing a puncture is often challenging in kidneys with congenital malformations or complex staghorn stones. We aim to perform a systematic review to examine data on in vivo applications, outcomes, and limitations of using artificial intelligence and robotics for access in PCNL. RECENT FINDINGS: The literature search was performed on November 2, 2022, using Embase, PubMed, and Google Scholar. Twelve studies were included. 3D in PCNL is useful for image reconstruction but also in 3D printing with definite benefits seen in improving anatomical spatial understanding for preoperative and intraoperative planning. 3D model printing and virtual and mixed reality allow for an enhanced training experience and easier access which seems to translate into a shorter learning curve and better stone-free rate compared to standard puncture. Robotic access improves the accuracy of the puncture for ultrasound- and fluoroscopic-guided access in both supine and prone positions. The potential advantage robotics are using artificial intelligence to do remote access, reduced number of needle punctures, and less radiation exposure during renal access. Artificial intelligence, virtual and mixed reality, and robotics may play a key role in improving PCNL surgery by enhancing all aspects of a successful intervention from entry to exit. There is a gradual adoption of this newer technology into clinical practice but is yet limited to centers with access and the ability to afford this.

RESUMO

We aim to assess the effect of Cavacurmin® on prostate volume (PV), lower urinary tract symptoms (LUTS) and micturition parameters in men after 1 year of therapy. From September 2020 to October 2021, data from 20 men with LUTS/benign prostatic hyperplasia and PV ≥40 mL who were on therapy with α1-adrenoceptor antagonists plus Cavacurmin® were retrospectively compared with 20 men on only α1-adrenoceptor antagonists. Patients were evaluated at baseline and after 1 year using the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), maximum urinary flow (Qmax) and PV. A Mann-Whitney U-test and Chi-square were used to assess the difference between the two groups. A comparison of paired data was performed with the Wilcoxon signed-rank test. Statistical significance was set at p-value < 0.05. There was no statistically significant difference in baseline characteristics between the two groups. At the 1-year follow-up, PV [55.0 (15.0) vs. 62.5 (18.0) mL, p = 0.04)], PSA [2.5 (1.5) ng/mL vs. 3.05 (2.7) vs. p = 0.009] and IPSS [13.5 (3.75) vs. 18 (9.25) p = 0.009] were significantly lower in the Cavacurmin® group. Qmax was significantly higher in the Cavacurmin® group [15.85 (2.9) vs. 14.5 (4.2), p = 0.022]. PV was reduced to 2 (5.75) mL in the Cavacurmin® group from baseline, while it increased to 12 (6.75) mL in the α1-adrenoceptor antagonists group (p < 0.001). PSA decreased in the Cavacurmin® group [-0.45 (0.55) ng/mL], whereas it increased in the α1-adrenoceptor antagonists group [0.5 (0.30) ng/mL, p < 0.001]. In conclusion, one-year Cavacurmin® therapy was able to block prostate growth with a concomitant decrease in PSA value from baseline. The association of Cavacurmin® with α1-adrenoceptor antagonists had a more beneficial effect compared to patients on α1-adrenoceptor antagonists alone but this needs further larger studies to be confirmed, particularly in the long-term.

RESUMO

Non-dilated obstructive uropathy (NDOU) is a condition of renal insufficiency characterized by functional kidney failure and inability of collective system to dilate because of several causes, e.g. hypotension, severe oliguria or dehydration. TUR-syndrome is a complication of bladder resection possibly leading to this condition through electrolytic disequilibrium after fluids reabsorption. We present the case of a patient with solitary kidney suffering from this uropathy regardless of mild electrolytic disorders and small bladder perforations. Prompt diagnosis and management with ureteral stent or nephrostomy tube are imperative in this setting.

RESUMO

Background: Giant angiomyolipoma is usually associated with genetic syndromes and complications (spontaneous rupture and bleeding, hematuria, hypertension) and mass-related symptoms (flank and abdominal pain). Case presentation: We present a case of a 20-year-old woman suffering from tuberous sclerosis who was referred to our hospital with a giant angiomyolipoma causing abdominal pain. A contrast-enhanced computed tomography showed a left angiomyolipoma, measuring 28 cm × 17 cm × 27 cm. After a multidisciplinary team discussion, the patient was submitted for a nephrectomy. Percutaneous temporary occlusion of the main renal artery was achieved through an endovascular balloon catheter. Through the balloon catheter guidewire, 2,500 IU of heparin was infused to reduce the risk of tumor vein thrombosis and venous embolism. This allowed a safe kidney manipulation through a left thoracoabdominal approach. The postoperative course was uneventful. Pathology showed a 40 cm × 30 cm × 9 cm and 10 kg AML. One year after surgery, the patient is on follow-up, and her estimated glomerular filtration is 120.5 ml/min/1.73 m2. Conclusion: The present case showed that the endovascular control of the main renal artery could be considered a useful approach to safely managing huge renal masses when renal hilar control is expected to be very difficult.

RESUMO

OBJECTIVES: Retrograde intrarenal surgery (RIRS) is commonly performed under general anesthesia (GA) because renal mobility during breathing may affect lithotripsy. However, spinal anesthesia (SA) is adopted in clinical practice due to clinical conditions that contraindicate GA. We aimed to compare results of RIRS for stones performed under GA compared to SA regarding stone-free rate (SFR) status and postoperative complications in a consecutive single-center series. METHODS: We retrospectively reviewed all patients who underwent RIRS for stones between 2017 and 2020. INCLUSION CRITERIA: age ≥ 18 years, renal stone burden deemed suitable for RIRS with a stone diameter ≤ 20 mm. EXCLUSION CRITERIA: stones >20 mm, urinary tract infection, bilateral surgery, second-look procedures, unmodifiable bleeding diathesis, <5mm asymptomatic lower calyx stones. SFR was defined as no residual fragment >3 mm at 6-12 weeks follow-up. The choice of anesthesia was a shared decision between anesthesiologists and patient preference. RESULTS: 230 patients were included in the analysis. Mean age was 57.50±13.73 years. 33% of stones were located in the pelvis. 28.7% of patients had multiple stones. Mean cumulative stone diameter was 16.60±6.54 mm. 63% of patients underwent RIRS under SA. There were no significant differences between the two groups in terms of preoperative characteristics, except for comor-bidity, significantly higher in the GA group. Mean time of operating room occupation was longer in the GA group (81.58±35.37 minutes) than in the SA group (72.85±25.91 minutes,p=0.033). Length of stay was shorter in the SA group (mean 2.2±1.66 days vs 3.46±5.88 in GA,p=0.019). Logistic regression showed that multiple stones in the collecting system were associated with residual fragments (HR 0.386, 95%CI 0.151-0.991,p=0.04). There were no statistically significant differences in overall and high-grade complications, and in SFR between SA (75.9%) and GA groups (70.6%,p=0.317). CONCLUSION: SA does not affect SFR and postoperative complications in patients who underwent RIRS in daily practice.

RESUMO

Objectives: Retrograde intrarenal surgery (RIRS) is commonly performed under general anesthesia (GA) because renal mobilityduring breathing may affect lithotripsy. However, spinal anesthesia (SA) is adopted in clinical practice due to clinical conditionsthat contraindicate GA. We aimed to compare results of RIRS for stones performed under GA compared to SA regarding stonefree rate (SFR) status and postoperative complications in a consecutive single-center series.Methods: We retrospectively reviewed all patients who underwent RIRS for stones between 2017 and 2020. Inclusion criteria:age ≥ 18 years, renal stone burden deemed suitable for RIRS with a stone diameter ≤ 20 mm. Exclusion criteria: stones >20mm, urinary tract infection, bilateral surgery, second-look procedures, unmodifiable bleeding diathesis, <5mm asymptomaticlower calyx stones. SFR was defined as no residual fragment >3 mm at 6-12 weeks follow-up. The choice of anesthesia was ashared decision between anesthesiologists and patient preference.Results: 230 patients were included in the analysis. Mean age was 57.50±13.73 years. 33% of stones were located in the pelvis.28.7% of patients had multiple stones. Mean cumulative stone diameter was 16.60±6.54 mm. 63% of patients underwent RIRSunder SA.

RESUMO

Worldwide, we have witnessed an expansion of robot-assisted laparoscopic surgery (RALS) and thanks to the global adoption of high-resolution diagnostic imaging technologies, an increased incidence of newly diagnosed prostatic, renal and bladder cancers has been recorded with concurrent second primary urological cancer diagnoses increasing by 1.5%. Diverse authors have reported their findings concerning synchronous multi-visceral malignances robotic treatment within the scientific literature. The aim of this study is to comprehensively review all reported articles describing concurrent upper and lower RALS using a singular robotic port scheme within the same intervention for renal malignances and concomitant prostatic or bladder cancers. To the best of our knowledge and vigorous literature search, this is the first study that comprehensively evaluates and reports all combined upper and lower urinary tract surgeries published so far. In carefully selected patients, thanks to multidisciplinary preoperative assessment and surgical planning a combined robotic approach can reduce the morbidity, complications, hospital admissions and the overall length of hospitalization.
