RESUMO
BACKGROUND: We aimed to assess the detection rate of overall PCa and csPCa, and the clinical impact of MRI/TRUS fusion targeted biopsy (FUSION-TB) compared to TRUS guided systematic biopsy (SB) in patients with different biopsy settings. METHODS: Three hundred and five patients were submitted to FUSION-TB, divided into three groups: biopsy naïve patients, previous negative biopsies and patients under active surveillance (AS). All patients had a single suspicious index lesion at mpMRI. Within these groups, we enrolled men underwent both to FUSION-TB and SB in the same session. Overall detection rate of PCa and csPCa for the two biopsy methods were compared separately between the three groups of patients. RESULTS: No differences were observed between the three groups concerning clinical and radiological characteristics. We found no differences in terms of overall PCa detection (66% vs. 63.8%, P=0.617) and csPCa detection (56.4% vs. 51.1%; P=0.225) concerning biopsy naïve patients. In patients previously submitted to a negative biopsy, FUSION-TB showed higher detection rate of csPCa compared to SB alone (41,3% vs. 27% respectively, P=0.038). In patients under AS, no differences were observed between FUSION-TB and SB in terms of overall PCa (50% vs. 73.1%) and csPCa (30.8% vs. 26.9%, respectively; P=0.705) detection. CONCLUSIONS: Our results suggest that in men with previously negative biopsy, FUSION-TB showed significantly higher diagnostic performance for clinically significant PCa as compared to SB. Combination of FUSION-TB and SB should be recommended in AS population to offer higher chance of csPCa diagnosis.

PURPOSE: Diagnosis of anterior prostate cancer (PCa) can be quite challenging, often leading to delay in treatment. mpMRI-guided biopsy (GB) has been introduced aiming to increase the number of diagnoses of clinically significant PCa with fewer cores. The aim of our study is to compare pathological findings of prostate biopsy, In-bore or Fusion technique, with histopathological evaluation of radical prostatectomy. METHODS: We prospectively collected data from 90 consecutive patients who underwent either In-bore or Fusion biopsy following the detection of an index suspicious lesion at mpMRI in the anterior part of the prostatic gland. Bioptical pathological findings were compared with pathological findings reported after robot-assisted radical prostatectomy. RESULTS: Patients who underwent In-bore GB had a higher rate of previous negative prostate biopsies (19% vs 44%, p = 0.02). Median number of bioptic cores taken (13 vs 2) and number of positive cores (3 vs 2) were significantly superior in the Fusion group compared to the In-bore group (p < 0.001 and p = 0.002, respectively), whilst clinical International Society of Urological Pathology (ISUP) grade was homogeneous within groups. The concordance between anterior lesions detected at biopsy and those reported in the histopathological finding of radical prostatectomy was very high, without statistically significant difference between groups. CONCLUSION: Both Fusion and In-bore GB are accurate in detecting anterior PCa, with enhanced precision detecting clinically significant tumours, as evidenced by pathologic examinations which confirmed the presence of index anterior PCa in > 50% of patients overall. Additional sextant biopsy is still required, especially among biopsy-näive patients, to avoid missing clinically significant PCa.

BACKGROUND: The aim, of this study was to investigate recurrence rates in patients with T1 renal cell carcinoma (RCC) undergone partial nephrectomy (PN), radiofrequency ablation (RFA) or cryoablation (Cryo). METHODS: We retrospectively evaluated data from 665 (81.4%), 68 (8.3%) and 83 (10.3%) patients who underwent PN, RFA and Cryo, respectively. Kaplan-Meier curves depict recurrence-free survival (RFS) rates in the overall population and after stratifying according to tumor's histology (namely, clear cell RCC and non-clear RCC) and size (namely <2 cm and 2-4 cm). Multivariable Cox regression model was used to identify predictors of recurrence. Cumulative-incidence plots evaluated disease recurrence and other causes of mortality (OCM). RESULTS: Patients referred to PN experienced higher RFS rate compared to those treated with RFA and Cryo at 60-month in the overall population (96.4% vs. 79.4% vs. 87.8%), in patients with clear cell RCC (93.3% vs. 75% vs. 80.4%) and in those with tumor of 2-4 cm (97.3% vs. 78% and 84.4%; all P≤0.01). In patients with non-clear cell RCC and with tumor <2cm, PN showed higher RFS rate at 60-month as compared to RFA (97.9% vs. 84.4% and 95.1% vs. 78.1%, respectively: all P≤0.02). At multi-variate analysis, ablative techniques (RFA [HR=4.03] and Cryo [HR=3.86]) were independent predictors of recurrence (all P<0.03). At competing risks analysis, recurrence rate and OCM were 7.3% and 1.3% vs. 25% and 7.2% vs. 19.9% and 19.9% for PN, RFA and Cryo, respectively. CONCLUSIONS: PN and Cryo showed similar RFS rates in patients with non-clear cell RCC and with renal mass <2cm.

BACKGROUND: We aimed at comparing perioperative outcomes in patients submitted to radical cystectomy followed by Fast Track (FT) protocol or standard management, and propose a definition of Trifecta, to improve standardized quality assessment for RC. METHODS: We considered 191 patients submitted to RC between January 2017 and January 2019. Patients followed FT or standard management according to surgeon's preference. Preoperative and intraoperative characteristics, alongside with postoperative outcomes were compared between the two groups. Trifecta was defined as follows: in-hospital stay (HS) ≤ 10 days, time to defecation (TtD) below the overall mean and no major (≥ Clavien-Dindo grade III) complications. Finally, Trifecta achievement rates were assessed in both groups. RESULTS: Seventy-five patients (39%) followed the FT protocol and 116 (61%) standard management. The two groups were homogeneous for preoperative, intraoperative and pathological characteristics. Patients in the FT group had shorter TtD (5 vs. 6 days P=0.006), HS (12 vs. 14 days P=0.008) and lower readmission rate (8% vs. 19% P=0.04). Early complication rates and grades were similar, while less late complications were found in FT group (6.7% vs. 21.6% P=0.006). Trifecta achievement rate was higher for FT group (31% vs. 8% P<0.001). Single-item failure percentages for HS, TtD and major grade complications were respectively 90%, 60% and 19%, with no difference between the two groups. CONCLUSIONS: FT protocol can safely consent faster bowel recovery and earlier discharge after RC, plus reducing readmission rates. Using a Trifecta incorporating essential perioperative outcomes, could improve standardized quality assessment for RC.

OBJECTIVE: To assess the economic impact of Holmium laser enucleation of prostate (HoLEP) in comparison with transurethral resection of prostate (TURP) and open prostatectomy (OP). METHODS: Between January 2017 and January 2018, we prospectively enrolled 151 men who underwent HoLEP, TURP or OP at tertiary Italian center, due to bladder outflow obstruction symptoms. Patients with prostate volume ≤ 70 cc and those with prostate volume > 70 cc were scheduled for TURP or HoLEP and OP or HoLEP, respectively. Intraoperative and early post-operative functional outcomes were recorded up to 6 months follow up. Cost analysis was carried out considering direct costs (operating room [OR] utilization costs, nurse, surgeons and anesthesiologists' costs, OR disposable products costs and OR products sterilization costs), indirect costs (hospital stay costs and diagnostics costs) and global costs as sum of both direct and indirect plus general costs related to hospitalization. Cost analysis was performed comparing patients referred to TURP and HoLEP with prostate volume ≤ 70 cc and men underwent OP and HoLEP with prostate volume > 70 cc respectively. RESULTS: Overall, 53 (35.1%), 51 (33.7%) and 47 (31.1%) were scheduled to HoLEP, TURP and OP, respectively. Both TURP, HoLEP and OP proved to effectively improve urinary symptoms related to BPE. Considering patients with prostate volume ≤ 70 cc, median global cost of HoLEP was similar to median global cost of TURP (2151.69 vs. 2185.61 , respectively; p = 0.61). Considering patients with prostate volume > 70 cc, median global cost of HoLEP was found to be significantly lower than median global cost of OP (2174.15 vs. 4064.97 , respectively; p ≤ 0.001). CONCLUSIONS: Global costs of HoLEP are comparable to those of TURP, offering a cost saving of only 11.4 in favor of HoLEP. Conversely, HoLEP proved to be a strong competitor of OP because of significant global cost sparing amounting to 1890.82 in favor of HoLEP.

The presence of amyloid deposits in bladder walls is a rare histological finding. It can be linked to primary (limited to bladder) or secondary (systemic, associated with chronic inflammatory disorders) amyloidosis. Secondary bladder involvement is very uncommon; it usually presents with gross hematuria, which is challenging to manage, due to frail bladder mucosa and/or necrosis. We present a case of 54-year old man with secondary bladder amyloidosis due to Crohn's disease, that caused gross hematuria and severe anemia, which was managed conservatively by endoscopic transurethral resection, diatermocoagulation, clot evacuation and urinary drainage by bilateral percutaneous nephrostomy, with spontaneous resolution. Secondary bladder amyloidosis is a rare condition that presents with severe hematuria, difficult to control with standard management. Owing to chronic nature of the disease, treatment should be aimed to a conservative approach whenever possible. In case of failure, invasive procedures should be considered as salvage therapies.

INTRODUCTION: The purpose of this study was to evaluate the impact of 3-dimensional (3D) digital reconstructions of renal models on the arterial clamping approach during partial nephrectomy (PN). PATIENTS AND METHODS: Fifty-seven patients with T1 renal mass, referred for PN, were prospectively enrolled in 2 groups: Group 1 (n = 32) with revision of both 2-dimensional (2D) computed tomography (CT) imaging and 3D virtual model before surgery; Group 2 (n = 25) with revision of 2D CT imaging. Segmentation of the 3D models from preoperative high-quality CT scan was achieved using D2P software. In a sub-analysis of patients treated with PN with the on-clamp approach (n = 36), the effective intraoperative level of arterial clamping was compared with the preoperative planning. RESULTS: In the sub-group of patients referred to PN with the on-clamp approach, the intraoperative selective clamping was performed in 12 (57.1%) patients of Group 1 and in 2 (13.3%) cases of Group 2 (P = .01). The intraoperative management of the renal pedicle was done as preoperatively planned in 61.9% of patients in Group 1 and in 86.6% of cases in Group 2 (P = .1). CONCLUSION: The 3D-guided plan of PN allows to perform selective clamping in higher proportion of patients compared with the standard 2D-guided approach without increasing intraoperative and postoperative complications.

PURPOSE: To perform an external validation of a recently published nomogram aimed to predict positive 68Ga-PSMA-11 PET/CT in patients with biochemical recurrence (BCR) after radical prostatectomy (RP) by Rauscher et al. (Eur Urol 73(5):656-661, 2018). METHODS: Overall, 413 PCa patients with BCR after RP (two consecutive PSA ≥ 0.2 ng/ml) and PSA value between 0.2 and 1 ng/ml were included. A multivariable logistic regression model was produced to assess the predictors of positive 68Ga-PSMA-11 PET/CT results. The performance characteristics of the model were assessed by quantifying the predictive accuracy, according to model calibration. Yuden's index was used to find the best nomogram's cut-off. Finally, decision curve analysis (DCA) was implemented to quantify the nomogram's clinical value. RESULTS: In the external cohort, the overall detection rate of 68Ga-PSMA-11 PET/CT was 44% vs. 64.7% in the original population. At multivariate analysis, PSA at 68Ga-PSMA-11 PET/CT (OR: 7.06, p < 0.001) and ongoing ADT at time of 68Ga-PSMA-11 PET/CT (OR: 2.07, p = 0.03) were the only independent predictors of PET/CT positivity. The predictive accuracy of nomogram was suboptimal and comparable to that reported in the original model (64% vs. 67%, respectively). The calibration plot indicated suboptimal concordance. The best nomogram's cut-off to predict positive 68Ga-PSMA-11 PET/CT was 35% (AUC = 0.61). In DCA, the nomogram revealed clinical net benefit when the threshold probabilities of positive 68Ga-PSMA-11 PET/CT is > 35%. CONCLUSION: We assessed similar suboptimal predictive accuracies in the external cohort compared to the original one. PSA and ongoing ADT were confirmed as positive predictors, and the most informative nomogram cut-off resulted 35%.

RESUMO
ABSTRACT Introduction and Objectives: We aim to present the use of 3D digital and physical renal model (1-5) to guide the percutaneous access during percutaneous nephrolithotripsy (PNL). Materials and Methods: We present the clinical case of a 30 years old man with left renal stone (25x15 mm). A virtual 3D reconstruction of the anatomical model including the stone, the renal parenchyma, the urinary collecting system (UCS) and the skeletal landmarks (lumbar spine and ribs) was elaborated. Finally, a physical 3D model was created with a 3D printer including the renal parenchyma, UCS and the stone. The surgeon evaluated the 3D virtual reconstruction and manipulated the printed model before surgery to improve the anatomical knowledge and to facilitate the percutaneous access. In prone position, combining ultrasound and fluoroscopy implemented by the preoperative anatomical planning based on the 3D virtual and printed model, an easy and safe access of the inferior calyx was achieved. Then, the patient underwent PNL using a 30 Fr Amplatz sheet with semi-rigid nephroscope and ultrasound energy to achieve a complete lithotripsy of the pelvic stone. Results: The procedure was safely completed with 1 single percutaneous puncture (time of puncture 2 minutes). Overall surgical time was 90 min. No intra and postoperative complications were reported. The CT scan performed before discharge confirmed a complete stone free state. Conclusion: The 3D-guided approach to PNL facilitates the preoperative planning of the puncture with better knowledge of the renal anatomy and may be helpful to reduce operative time and improve the learning curve.

PURPOSE: The aim of this study was to assess corneal hysteresis (CH) and corneal resistance factor (CRF) in healthy subjects, to evaluate the relationship with age, and to investigate possible associations with other ocular factors. METHODS: Four hundred Italian subjects (male-to-female ratio, 168:232; mean age, 58.8 ± 17.2 years) were included and divided into 5 subgroups based on age. CH, CRF, and central corneal thickness (CCT) were measured by using the Ocular Response Analyzer and the integrated handheld pachymeter, and their relationship with gender, age, and ocular factors was evaluated. RESULTS: The mean CH, CRF, and CCT values were 10 ± 1.6 mm Hg, 10.5 ± 1.7 mm Hg, and 532.2 µm, respectively. Women had a lower mean CH (9.9 vs. 10.2 mm Hg; P = 0.04) and CRF (10.3 vs. 10.8 mm Hg; P = 0.03) than did men. The youngest subjects had the highest CH (11.2 ± 1.5 mm Hg), whereas the oldest patients had the lowest CH values (9 ± 1.1 mm Hg). No significant differences in CRF were observed between age groups. CH and CRF showed a positive correlation (r = 0.58; P < 0.001), and both had a positive association with CCT (r = 0.27; P < 0.001 and r = 0.57; P < 0.001, respectively). The strongest correlations were observed between Goldmann-correlated intraocular pressure (IOP) and corneal-compensated IOP (r = 0.68; P < 0.001) and between Goldmann-correlated IOP and Goldmann applanation tonometry (r = 0.88; P < 0.001). CONCLUSIONS: Gender and advancing age may influence corneal biomechanical properties. In our population, CH decreased with aging, and men demonstrated a higher CH and CRF than women did. Further, CH, CRF, and CCT were significantly related.
