FloRIN reconfiguration technique was introduced in 2016 according to the IDEAL-Collaboration Guidelines, with the attempt to conjugate the advantages of both intracorporeal neobladder and robotic assistance. Herein we report functional outcomes of FloRIN reservoir, specifically focusing on urodynamic features.Consecutive patients treated with RARC and FloRIN reconstruction were prospectively collected from February 2016 to June 2020. Only patients with a minimum 6-month follow up were analyzed to obtain a stable grade of neobladder maturation before performing the urodynamic study (UDS). The FACT-BL and the QLQ-C30 EORTC questionnaires were used to evaluate urinary function and health-related QoL. Results were compared with a contemporary series of patients treated at the same Institution with open radical cystectomy (ORC) and Vescica Ileale Padovana (VIP).One hundred patients entered the study and 69 patients had complete functional data. Overall, 52 (75.4%) patients reached the daytime continence. Among these, 28 (40.6%) were dry (no pads during daytime), while 24 (34.8%) used one pad/12 h. Night-time continence was achieved by 45 (65.2%) patients. Complete UDS findings were available for 28 patients. No statistically significant differences were found with the VIP-ORC group except for neobladder compliance, being higher in the FloRIN group (p = 0.03). When evaluating QoL scores, RARC with FloRIN reconfiguration showed a better continence recovery, as well as a higher improvement in urgency domain (p = 0.01), psychological status (0.02) and physical self-acceptance (p = 0.02), compared to the VIP-ORC group.The FloRIN technique showed excellent functional outcomes when compared to the referral VIP-ORC procedure.

Although cancer-associated fibroblasts (CAF) are key determinants in the malignant progression of cancer, their functional contribution to this process is still unclear. Analysis of the mutual interplay between prostate carcinoma cells and CAFs revealed a mandatory role of carcinoma-derived interleukin-6 in fibroblast activation. In turn, activated fibroblasts through secretion of metalloproteinases elicit in cancer cells a clear epithelial-mesenchymal transition (EMT), as well as enhancement of tumor growth and development of spontaneous metastases. CAF-induced EMT leads prostate carcinoma cells to enhance expression of stem cell markers, as well as the ability to form prostaspheres and to self-renew. Hence, the paracrine interplay between CAFs and cancer cells leads to an EMT-driven gain of cancer stem cell properties associated with aggressiveness and metastatic spread.

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

BackgroundDue to the pandemic emergency caused by COVID-19, many countries were forced to apply a variety of measures such as quarantine and full national lockdown in order to contain the contagion. Medication adherence to chronic diseases may have been negatively influenced by restrictions due to the COVID-19 pandemic. The purpose of this study is to investigate adherence to urological therapies of patients with lower urinary tract symptoms (LUTSs) secondary to benign prostatic hyperplasia (BPH) during the COVID-19 lockdown period.MethodsIn this cohort study, we included a total of 151 male patients who were prescribed medications for LUTSs/benign prostatic enlargement (BPE) between January 2019 and December 2020. The prescriptive data of the following medications were collected: alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARIs), 5-phosphodiesterase inhibitors (PDE5-i), antimuscarinics, and phytotherapy (i.e., Serenoa repens). According to adherence or discontinuation of therapy, patients were divided into two groups: those who took their medications for a minimum of 6 months during the index period were considered in the “Medication adherence group” and those whose treatment was considered “discontinued” if it was interrupted for a 1-month period.ResultsOverall, the median age was 69.0 (interquartile range [IQR]: 63.0–74.0), the median International Prostate Symptom Score (IPSS) before the lockdown was 15.0 (IQR: 11.0–18.0), and the median IPSS–quality of life (IPSS-QoL) before the lockdown was 2.0 (IQR: 2.0–3.0). During the lockdown, 19 patients (12.58%) stopped taking their medications due to the pandemic situation: six (31.58%) stopped phytotherapy, two stopped AB+phytotherapy (10.53%), five stopped AB (26.32%), three stopped 5-ARIs (15.79%), one stopped antimuscarinics (5.26%), and two stopped other combination therapies (p < 0.01). Among the patients who stopped therapy, five (26.31%) reported the presence of worsening symptoms (score ≥ 3), while 14 (73.69%) reported the absence of worsening symptoms (score < 3). During the lockdown, five (3.31%) patients required hospitalization: three (1.99%) for acute urinary retention and two (1.32%) for urinary tract infection.ConclusionsThe rate of medication adherence for LUTSs/BPE during COVID-19 was 86.75%, but 13.25% of the patients had their treatments interrupted due to the pandemic situation. This rate determined a slight increase in symptoms with a potential impact on hospitalization. These results should be taken into account in order to develop adequate strategies in telehealth to maintain medication adherence for chronic diseases.

Robot-assisted extravesical ureteral reimplantation (REVUR) is a well established approach for surgical treatment of pediatric vesicoureteral reflux (VUR). However, further evidence is needed to confirm its efficacy even in case of complex anatomy.This study aimed to further confirm the evidence that REVUR is safe and effective in both simple and complex ureter anatomy.The charts of all patients with VUR, who received REVUR in 6 different institutions over a 5-year period, were retrospectively reviewed. Patients with both simple and complex ureter anatomy were included. Patient demographics, surgical variables, and post-operative results were assessed. VUR resolution was defined as either being resolved VUR on voiding cystourethrogram (VCUG) or clinically without symptoms during the follow-up.Fifty-seven patients with median age of 6.9 years (range 4.5-12), receiving REVUR in the study period, were included. Eighteen (31.6%) patients had complex anatomy and included prior failed endoscopic injection (n = 13), complete ureteral duplication (n = 2), periureteral diverticulum (n = 2), ectopic megaureter requiring dismembering (n = 1). The median operative time was 155 min for unilateral and 211.5 min for bilateral repairs. The clinical + radiographic VUR resolution rate was 96.5%. Post-operative complications (Clavien 2) included urinary retention following bilateral repair (n = 5, 8.7%), febrile urinary tract infection (UTI) (n = 6, 10.5%) and gross hematuria (n = 3, 5.2%). Comparative analysis between simple and complex cases showed that REVUR was faster in simple cases in both unilateral [p = 0.002] and bilateral repair [p = 0.001] and post-operative urinary retention was more frequent in simple cases [p = 0.004] and in patients with pre-operative bowel and bladder dysfunction (BBD) [p = 0.001] (Table).This series confirmed that the robot-assisted technique was feasible even in cases with complex anatomy using some technical refinements, that justified the longer operative times in both unilateral and bilateral cases. An interesting finding of this study was the correlation emerged between BBD and risk of post-operative urinary retention and VUR persistence. Our results also excluded any significant correlation between complex cases and risk of post-operative urinary retention. The main study limitations included the retrospective and nonrandomized design, the small number of cases and the arbitrary definition of complex anatomy.REVUR was safe and effective for management of VUR in both simple and complex ureter anatomy. Complex REVUR required slightly longer operative times, without significant differences in post-operative mordidity and success rates. Aside from complex anatomy, BBD emerged as the main risk factor associated with surgical failure and post-operative morbidity.

Purpose This multi-institutional study aimed to assess the outcomes of laparoscopic ureterocalicostomy (LUC) and robot-assisted laparoscopic ureterocalicostomy (RALUC) and compare them with laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP) in children with pelvi-ureteric junction obstruction (PUJO). Methods The data of 130 patients (80 boys), with median age 7.6 years and median weight 33.8 kg, receiving minimally invasive treatment of PUJO over a 6-year period, were retrospectively analyzed. Patients were grouped according to the operative approach: G1 included 15 patients, receiving LUC (n = 9) and RALUC (n = 6), and G2 included 115 patients, receiving LP (n = 30) and RALP (n = 85). Patient characteristics and operative outcomes were compared in both groups. Results The median patient age and weight were significantly higher in G1 than in G2 [p = 0.001]. The median operative time was similar in both groups (157.6 vs 150.1 min) [p = 0.66] whereas the median anastomotic time was shorter in G1 than in G2 (59.5 vs 83.1 min) [p = 0.03]. The surgical success rate was similar in both groups (100% vs 97.4%) [p = 0.33]. Post-operative complications rate was higher in G1 than in G2 (20% vs 6.1%) but all G1 complications were Clavien 2 and did not require re-intervention. Conclusion LUC/RALUC can be considered safe and effective alternative approaches to LP/RALP for PUJO repair and reported excellent outcomes as primary and salvage procedures. Robot-assisted technique was the preferred option to treat most patients with recurrent PUJO in both groups.

Purpose: To compare surgical scars assessed by a validated patient reported outcome questionnaire in children undergoing open (OP), laparoscopic (LP), or robotic-assisted (RALP) pyeloplasty. Secondary aim was to assess the influence on the outcomes of variables such as gender or body mass index (BMI). Materials and methods: Observational, cross-sectional, multicentric study of patients undergoing primary pyeloplasty between age 10- and 18-year at 5 tertiary Italian institutions in the period 01/2010 to 12/2019. Of 227 eligible patients, 114 (50%) participated. OP was performed in 37 (32%), LP in 30 (26%) and RALP in 47 (41%), After a median (IQR) follow-up of 5.2 (2.3-7.8) years, scars were measured and assessed by a validated Patient Scar Assessment Questionnaire (PSAQ). Scores were compared among techniques and in accordance to several variables. Results: The median length of the surgical scar at follow-up was significantly larger (p

Background: Phytotherapeutic agents aroused an increasing interest either as alternative or in addition to conventional therapy in the management of BPH. The aim of the article was to evaluate the clinical and functional changes after add-on treatment with Serenoa repens associated with Solanum lycopersicum, lycopene and bromelain in patients with BPH presenting with mild to moderate LUTS and previously treated only with Alfuzosin over a 6–12 months period. Materials and methods: Between January and July 2019, patients with symptomatic BPH already on treatment with Alfuzosin (Al) 10 mg for at least 6–12-month were enrolled at three academic referral centres, included in a prospective treatment group, and managed with a combination treatment of Al and 6-month daily oral single-tablet supplementation of Serenoa repens and Solanum lycopersicum + lycopene + bromelain (SeR + SL + Ly + Br). A retrospective control group with comparable baseline characteristics was obtained by performing a propensity score matching from a database of 434 patients managed with Alfuzosin 10 mg/day only over a 6–12 months period between March 2015 and December 2018. IPSS, QoL questionnaires, voiding diary assessment, postvoid residual volume (PVR), maximal (Qmax) and average (Qave) urinary flow rates were evaluated at baseline in the treatment group at the moment of patient accrual, in the control group after 6-month of treatment with alfuzosin, and thereafter at 3 and 6 months in both groups. Results: Overall, 250 patients entered the study (n = 125 treatment group, n = 125 control group). Total IPSS score significantly decreased at 6-month assessment from baseline in the treatment vs control group (17 [IQR: 12–20] vs 12 [IQR: 9–14], p = 0.02) with a significative storage symptoms improvement detected both at 3- (p = 0.03) and 6-month evaluation (p = 0.001). PVR significantly improved at each follow-up visit with the most relevant reduction at 6-month assessment (125 cc vs. 102 cc, p = 0.02). Moreover, a significative improvement in LUTS-related quality of life (QoL) was recorded at 3- and 6-month assessment with a median decrease of −1 and −2 (p = 0.05 and p = 0.001 respectively) from baseline. Conclusions: Combination treatment with AB and SeR + SL + Ly + Br led to meaningful improvements in LUTS severity compared to AB as monotherapy, after a 6-month treatment period in men with mild to moderate LUTS/BPH.

Purpose: Three-dimensional (3D) virtual models have recently gained consideration in the partial nephrectomy (PN) field as useful tools since they may potentially improve preoperative surgical planning and thus contributing to maximizing postoperative outcomes (1-5). The aim of the present study was to describe our first experience with 3D virtual models as preoperative guidance for robot-assisted PN. Materials and methods: Data of patients with renal mass amenable to robotic PN were prospectively collected at our Institution from January to April 2020. Using a dedicated web-based platform, abdominal CT-scan images were processed by M3DICS (Turin, Italy) and used to obtain 3D virtual models. 2D CT images and 3D models were separately assessed by two different highly experienced urologists to assess the PADUA score and risk category and to forecast the surgical strategy of the single cases, accordingly. Results: Overall, 30 patients were included in the study. Median tumor size was 4.3cm (range 1.3-11). Interestingly, 8 (26.4%) cases had their PADUA score downgraded when switching from 2D CT-scan to 3D virtual model assessment and 4 (13.4%) cases had also lowered their PADUA risk category. Moreover, preoperative off-clamp, selective clamping strategy and enucleation resection strategy increased from CT-scan to 3D evaluation. Conclusion: 3D virtual models are promising tools as they showed to offer a reliable assessment of surgical planning. However, the advantages offered by the 3D reconstruction appeared to be more evident as the complexity of the mass raises. These tools may ultimately increase tumor's selection for PN, particularly in highly complex renal masses. Disclosure of potential conflicts of interest: The authors declare they do not have conflict of interests. Informed consent: Informed consent was obtained from all individual participants included in the study. All the procedures were in accordance with the ethical standards of the institutional and national research Committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.

The management of UCs remain controversial, especially for UCs with duplex collecting systems that still represent a great challenge in paediatric urology. Several approaches have been used and a shared management is not yet validated.Aim of our study is to evaluate the results of the endoscopic treatment of UC comparing ortothopic single-system UC and ectopic duplex-system UC over a 10-year period in a single referral tertiary center. Success was defined as resolution of dilation, lack of urinary infections and preservation of renal function.We retrospectively reviewed medical records of children with a diagnosis of UC who underwent endoscopic puncture at our division from January 2009 to January 2019. Patients were divided in two groups: Group A composed of patients with ectopic UC associated with renal duplex system and Group B with orthotopic UC in single collecting system.We identified 48 paediatric patients treated with transurethral primary endoscopic incision. Groups result homogeneous for clinical and pathological characteristics. The only statistical significative difference between the two samples was the age at diagnosis (p value with Yates correction = 0.01).We considered as a therapeutic success infections control and the elimination of obstruction with preservation of global kidney function. Based on that, our success rate after single (77%) or double (92%) endoscopic treatment is higher than data reported in literature. Differently from previous studies, vescico-ureteral reflux without UTIs was not considered as a failure of the procedure. The present study has some limitations: it is a retrospective and monocentric serie and it lacked a longer follow-up; on the other hand, it has been conducted on a quite large sample size and it is one of the few studies that compares the endoscopic treatment between orthotopic and ectopic UC.Our data report primary endoscopic puncture of ureterocele as a simple, effective, and safe procedure also in long-term follow up. This technique avoids the need for additional surgery in the majority of the patients, also in the case of an ectopic UC associated to a duplex system.
