RESUMEN

BACKGROUND AND PURPOSE: Urinary continence (UC) represents the main non-oncological goal in patients undergoing robotic-assisted radical prostatectomy (RARP). To evaluate the efficacy in early UC achievement, we described a new sling technique using the retrotrigonal muscular layer (TZ sling) combined with total anatomical reconstruction (TAR). PATIENTS AND METHODS: We prospectively enrolled 407 consecutive prostate cancer (PC) patients undergoing RARP between May 2017 and January 2020. The first 250 patients underwent only TAR, while the following 157 patients TAR + TZ sling, by isolating and anchoring the retrotrigonal muscular layer to the pubic bone with 2 bilateral sutures. We defined UC as ≤ 1 pad/die, which was assessed after catheter removal at 1, 4 and 12wk using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score. Sling-related operative time and post-operative complications were analyzed. RESULTS: In the TAR group, the UC rates at the 1, 4 and 12wk were 58%, 66% and 86%; in the TAR + TZ sling group 72%, 76% and 88%, respectively. A statistically significant difference was observed in the two groups at 1wk (p = 0.0049) and 4wk (p = 0.035) favoring the TZ sling surgical strategy. This difference in UC rates was lost at 12wk (p ≥ 0.05). No statistically significant differences in operative time, acute urinary retentions and other complication rates were observed between the two groups (p = NS). CONCLUSIONS: We have described a new, safe, feasible modification of RARP using a sling with the retrotrigonal muscular layer associated with TAR. We have demonstrated a statistically significant improvement in early UC rate in patients who are undergoing TAR and TZ sling compared to undergoing only TAR.

RESUMEN

PURPOSE: To investigate prostate cancer (PC) detection rate, employing endorectal multiparametric 3-tesla magnetic resonance imaging (MRI) driving subsequent cognitive systematic prostatic biopsy (CSPB) versus a homogenous group of patients who did not undergo endorectal MRI. MATERIALS AND METHODS: A series of patients with a first negative biopsy were enrolled in the study. Patients were randomized into two groups: Group A: patients underwent MRI and subsequent CSPB; Group B: patients that did not undergo MRI. Each patient underwent a 13-core sampling. Patients from Group A had four cores more for each MRI suspected lesion. The cancer detection rate was calculated for each group with regard to possible matches or mismatches between MRI evidence and pathological reports. RESULTS: Two hundred consecutive patients were investigated. Fifty out of 200 (25 %) patients had a diagnosis of PC, 24 in Group A and 26 in Group B. In Group A, 67 patients (67 %) were positive for suspected lesions at the MRI. The mismatch between MRI findings and the CSPB outcome was 61 % with an MRI-driven detection rate of 15 %. Group B detection rate was 26 % with no significant differences versus Group A (P = NS). Patient discomfort was higher in Group A (82 %). The accuracy of CSPB was 41 % with a positive predictive value of 22.3 %. This rate is lower in high-grade cancers (11.9 %). The cost-effectiveness was higher in Group A. CONCLUSIONS: Prostate cancer detection rate does not improve by CSPB. The accuracy of CSPB was lower in high-grade PC, and a higher cost was found with CSPB.

RESUMEN

BACKGROUND: Nonbacterial prostatitis, together with chronic pelvic pain syndrome, accounts for 90-95 % of prostatitis cases. Anti-inflammatory medications are commonly used to reduce storage/inflammatory symptoms that can deteriorate quality of life. The purpose of this study was to observe the efficacy and safety of beclomethasone dipropionate rectal suppositories (Topster®) in inflammations of the lower urinary tract in men. METHODS: Patients underwent diagnostic and therapeutic protocols according to current evidence-based practice. Efficacy assessments: voiding parameters, perineal pain, International Prostate Symptom Score (IPSS), digital rectal examination (DRE). Adverse events and patient compliance were recorded throughout the study. RESULTS: One hundred eighty patients were enrolled, mean age 52 ± 14.97. Most frequent diagnosis: nonbacterial prostatitis (85 %). All patients completed visits 1 and 2. All patients were treated with beclomethasone dipropionate (BDP) suppositories, 136/180 also with Serenoa repens (SR) extract. Antibiotics were rarely required. 162/180 patients presented clinically significant improvements and terminated treatment. Mean change vs. baseline in voiding frequency: -3.55 ± 2.70 n/day in patients taking only BDP and -3.68 ± 2.81 n/day in those taking both BDP and SR (P<.0001 in both groups). Uroflowmetry improved significantly; change from baseline 3.26 ± 5.35 ml/s in BDP only group and 5.61 ± 7.32 ml/s in BDP + SR group (P = 0.0002 for BDP, P<.0001 for BDP + SR). Urine stream normal in 35 % of patients at visit 1 and 57.22 % of patients at visit 2. Mean change in perineal pain, on 0-10 VAS, -0.66 ± 2.24 for BDP only group (P = 0.0699) and -1.37 ± 2.40 for BDP + SR group (P<.0001). IPSS increased at visit 2. No adverse events were reported. For all parameters, none of the comparisons between groups was found to be statistically significant. CONCLUSION: This study confirmed the drug's good safety profile. We also observed an improvement in the main storage symptoms and clinical findings associated with lower urinary tract inflammation in patients treated with beclomethasone dipropionate suppositories.

RESUMEN

The electronic nose is able to provide useful information through the analysis of the volatile organic compounds in body fluids, such as exhaled breath, urine and blood. This paper focuses on the review of electronic nose studies and applications in the specific field of medical diagnostics based on the analysis of the gaseous headspace of human urine, in order to provide a broad overview of the state of the art and thus enhance future developments in this field. The research in this field is rather recent and still in progress, and there are several aspects that need to be investigated more into depth, not only to develop and improve specific electronic noses for different diseases, but also with the aim to discover and analyse the connections between specific diseases and the body fluids odour. Further research is needed to improve the results obtained up to now; the development of new sensors and data processing methods should lead to greater diagnostic accuracy thus making the electronic nose an effective tool for early detection of different kinds of diseases, ranging from infections to tumours or exposure to toxic agents.

RESUMEN

PURPOSE: We established diagnostic accuracy in terms of the sensitivity and specificity with which a rigorously trained canine olfactory system could recognize specific volatile organic compounds of prostate cancer in urine samples. MATERIALS AND METHODS: Two 3-year-old female German Shepherd Explosion Detection Dogs were trained to identify prostate cancer specific volatile organic compounds in urine samples. They were tested on 362 patients with prostate cancer (range low risk to metastatic) and on 540 healthy controls with no nonneoplastic disease or nonprostatic tumor. This cross-sectional design for diagnostic accuracy was performed at a single Italian teaching hospital and at the Italian Ministry of Defense Military Veterinary Center. RESULTS: For dog 1 sensitivity was 100% (95% CI 99.0-100.0) and specificity was 98.7% (95% CI 97.3-99.5). For dog 2 sensitivity was 98.6% (95% CI 96.8-99.6) and specificity was 97.6% (95% CI 95.9-98.7). When considering only men older than 45 years in the control group, dog 1 achieved 100% sensitivity and 98% specificity (95% CI 96-99.2), and dog 2 achieved 98.6% sensitivity (95% CI 96.8-99.6) and 96.4% specificity (95% CI 93.9-98.1). Analysis of false-positive cases revealed no consistent pattern in participant demographics or tumor characteristics. CONCLUSIONS: A trained canine olfactory system can detect prostate cancer specific volatile organic compounds in urine samples with high estimated sensitivity and specificity. Further studies are needed to investigate the potential predictive value of this procedure to identify prostate cancer.

RESUMEN

OBJECTIVE To provide evidence-based recommendations on bladder cancer management METHODS A multidisciplinary guideline panel composed of urologists, medical oncologists, radiotherapists, general practitioners, radiologists, epidemiologists and methodologists conducted a structured review of previous reports, searching the Medline database from 1 January 2004 to 31 December 2008. The milestone papers published before January 2004 were accepted for analysis. The level of evidence and the grade of the recommendations were established using the GRADE system. RESULTS In all, 15 806 references were identified, 1940 retrieved, 1712 eliminated (specifying the reason for their elimination) and 971 included in the analysis, as well as 241 milestone reports. A consensus conference held to discuss the discrepancies between the scientific evidence and the clinical practice was then attended by 122 delegates of various specialities. CONCLUSION Recommendations on bladder cancer management are provided.

RESUMEN

In the past two decades, the treatment landscape for patients with metastatic renal cell carcinoma has significantly changed thanks to the approval of several targeted molecular therapies (VEGF and mTOR inhibitors) and recently immune-checkpoint inhibitors. The Italian Association of Medical Oncology (AIOM) Renal Cell Cancer (RCC) Guidelines Panel has developed clinical guidelines to provide evidence-based information and recommendations to oncologists, urologists and all professionals involved in the management of patients with renal cell cancer.

RESUMEN

Renal cell carcinoma (RCC) accounts for 3 % of adult solid tumors, with the highest incidence between 50 and 70 years of age. Nephron-sparing surgery was initially reserved to patients with small renal masses detected in anatomically or functionally solitary kidney or in the presence of multiple bilateral tumors or hereditary forms of RCC, which posed a high risk of developing a tumor in the contralateral kidney. Nowadays, partial nephrectomy (PN) has grown up to an established approach for the treatment of small renal masses. In patients with T1a-staged RCCs, PN has proven to be associated with better survival, long-term renal function preservation with lower dialysis need or renal transplantation. Currently, most of the kidney masses are incidentally detected, up to 40 %, with smaller size due to the widespread use of imaging modalities such as ultrasound, computed tomography and magnetic resonance. Here we review the role of open PN in the management of small renal masses particularly focusing on indications, oncological outcomes and comparison with laparoscopic and robotic PN. Recent studies demonstrate that PN confers better survival, oncologic equivalence and lower risk of severe chronic kidney disease compared to radical nephrectomy becoming then the gold-standard surgical technique, even if increasingly challenged by laparoscopic and/or robot-assisted partial nephrectomy which in the hands of experts seems to achieve comparable outcome results albeit with slightly higher complication rate.

RESUMEN

BACKGROUND: The aim of this prospective, multicentre, observational study was to evaluate the initial diagnostic procedures for lower urinary tract symptoms (LUTS) carried out by Italian general practitioners (GPs). METHODS: Data were collected from 445 GPs in Italy regarding the initial clinical decisions and diagnostic procedures adopted for the management of 1399 male patients with LUTS aged >or= 50 years. RESULTS: 50.3% of patients were managed by the GP,4.9% were referred to the urologist immediately and 44.8% after carrying out some diagnostic procedures. A digital rectal examination was performed in only one-third of the patients, many of whom were not subsequently referred to the urologist (26.4%). Laboratory tests that are usually recommended (i.e. PSA, urinalysis and serum creatinine) were undertaken in 98.3% of patients, while tests that are generally considered optional (such as flowmetry) were undertaken in up to 64%. Other generally not recommended investigations, such as ultrasonography, were carried out in 77.2%. The mean time to diagnosis was significantly shorter when the urologist was not involved (36.0 days for GP only management vs 51.4 days for immediate referral and vs 43.4 days for delayed referral (p = 0.0003). CONCLUSIONS: Our findings show a propensity for the majority of Italian GPs to deal with LUTS patients in a primary setting without immediate referral to the urologist. In principle, this trend could be beneficial for the patient (i.e. by reducing time to diagnosis) and cost saving for the national health system. However, the diagnostic procedures selected by the GPs were not in line with best evidence practice recommendations. Shared-care protocols involving both GPs and urologists may contribute to better implementation of the guidelines on the management of LUTS and benign prostatic hyperplasia in Italy.

RESUMEN

OBJECTIVE: To assess whether adopting a shared protocol between urologists and general practitioners (GPs) might change diagnostic procedures and referral patterns in the management of men with lower urinary tract symptoms (LUTS). SUBJECTS AND METHODS: Forty-five urological centres and 263 GPs in Italy participated in this prospective study. Procedures adopted by GPs for evaluating five consecutive patients (aged > or = 50 years) were compared before (phase 1) and after (phase 2) implementation of the shared protocol. An evidence-based diagnostic algorithm was developed and approved by participating urologists and presented to local GPs at a training session. Protocol modifications were allowed after discussion with GPs. Direct costs of diagnostic procedures carried out before and after implementing the protocol were calculated from the perspective of the national health service. RESULTS: In all, 903 patients were evaluable in phase 1 and 856 in phase 2. Implementation of the protocol did not change referral patterns, with about half the patients being managed entirely by GPs. The use of a digital rectal examination by GPs increased from 32% to 41%, use of transrectal and suprapubic ultrasonography decreased from 33% to 23% and 53% to 44%, respectively, (all P < 0.001) and use of the International Prostate Symptom Score increased from 4.5% to 23.1% (P < 0.001). Overall, protocol-recommended tests were used more frequently, while those not recommended decreased after implementing the protocol. However, overuse of the tests not recommended (i.e. urine culture and free/total prostate specific antigen ratio) remained high. The mean cost per patient of diagnostic procedures ordered by GPs decreased from Euros 71.82 to Euros 61.93, with Euros 9.9 saved for each patient. CONCLUSION: Our intervention failed to decrease the percentage of cases of LUTS being referred to specialists, but was moderately effective in inducing changes in the diagnostic management by GPs that were indicative of increased compliance with best-practice principles, and produced cost savings of 13.8%.
