RESUMO
PURPOSE: Aim of the present study is to describe our robot-assisted simple prostatectomy technique and to report 6-month surgical and clinical outcomes. METHODS: Eighty men were consecutively submitted to robot-assisted simple prostatectomy in our institution from October 2019 to October 2020. All procedures were performed by the same surgical team. Diagnostic preoperative assessment was based on history, symptoms evaluation by International Prostate Symptom Score, digital rectal examination, flowmetry with post-void residual volume measurement by abdominal ultrasound, prostatic volume estimation by MRI, PSA dosage. Under combined general and subarachnoid anesthesia, surgery was performed via a transperitoneal approach using a Da Vinci Si system in the four-arm configuration. Operative time, blood loss, hospital stay, catheterization time, intraoperative and postoperative complications were assessed. Clinical postoperative 6 months of evaluation was based on physical examination, flowmetry with post-void residual volume measurement, PSA dosage, and International Prostate Symptom Score. RESULTS: Mean operative time was 105.29 min, mean hospital staying 5.4 days. Blood loss was low in all cases and only 2 patients received transfusion. Catheterization time was 7 days. According to the Clavien-Dindo classification, only minor (grade I and grade II) intraoperative and postoperative complications were observed. At 6-month postoperative assessment, a statistically significant increase of urinary flow indexes and bladder capacity was recorded, as a significant reduction of urinary residual volume. No patient experienced stress urinary incontinence and the mean postoperative IPSS score was significantly reduced to 4.3. Two patients were diagnosed with incidental prostatic cancer at the histopathological examination. CONCLUSIONS: Data collected in our experience on a large cohort confirm efficacy and safety of Robot-Assisted Simple Prostatectomy. This procedure allows both short operative time and hospital staying, with low incidence of perioperative complications. This surgical technique can therefore be considered a valid alternative to other procedures for the surgical treatment of large volume prostates. Randomized prospective and comparative studies are warranted in the future to assess if different RASP techniques provide similar surgical and functional outcomes.

PURPOSE: A relevant challenge for the improvement of clear cell renal cell carcinoma management could derive from the identification of novel molecular biomarkers that could greatly improve the diagnosis, prognosis, and treatment choice of these neoplasms. In this study, we investigate whether quantitative parameters obtained from computed tomography texture analysis may correlate with the expression of selected oncogenic microRNAs. METHODS: In a retrospective single-center study, multiphasic computed tomography examination (with arterial, portal, and urographic phases) was performed on 20 patients with clear cell renal cell carcinoma and computed tomography texture analysis parameters such as entropy, kurtosis, skewness, mean, and standard deviation of pixel distribution were measured using multiple filter settings. These quantitative data were correlated with the expression of selected microRNAs (miR-21-5p, miR-210-3p, miR-185-5p, miR-221-3p, miR-145-5p). Both the evaluations (microRNAs and computed tomography texture analysis) were performed on matched tumor and normal corticomedullar tissues of the same patients cohort. RESULTS: In this pilot study, we evidenced that computed tomography texture analysis has robust parameters (eg, entropy, mean, standard deviation) to distinguish normal from pathological tissues. Moreover, a higher coefficient of determination between entropy and miR-21-5p expression was evidenced in tumor versus normal tissue. Interestingly, entropy and miR-21-5p show promising correlation in clear cell renal cell carcinoma opening to a radiogenomic strategy to improve clear cell renal cell carcinoma management. CONCLUSION: In this pilot study, a promising correlation between microRNAs and computed tomography texture analysis has been found in clear cell renal cell carcinoma. A clear cell renal cell carcinoma can benefit from noninvasive evaluation of texture parameters in adjunction to biopsy results. In particular, a promising correlation between entropy and miR-21-5p was found.

The aim of the study was to evaluate the long-term outcomes of pelvic floor muscle (PFM) rehabilitation in males with lifelong premature ejaculation (PE), using intravaginal ejaculatory latency time (IELT) and the self-report Premature Ejaculation Diagnostic Tool (PEDT) as primary outcomes. A total of 154 participants were retrospectively reviewed in this study, with 122 completing the training protocol. At baseline, all participants had an IELT ≤60 s and PEDT score >11. Participants completed a 12-week program of PFM rehabilitation, including physio-kinesiotherapy treatment, electrostimulation, and biofeedback, with three sessions per week, with 20 min for each component completed at each session. The effectiveness of intervention was evaluated by comparing the change in the geometric mean of IELT and PEDT values, from baseline, at 3, 6, and 12 months during the intervention, and at 24 and 36 months postintervention, using a paired sample 2-tailed t-test, including the associated 95% confidence intervals. Of the 122 participants who completed PFM rehabilitation, 111 gained control of their ejaculation reflex, with a mean IELT of 161.6 s and PEDT score of 2.3 at the 12-week endpoint of the intervention, representing an increase from baseline of 40.4 s and 17.0 scores, respectively, for IELT and PEDT (P < 0.0001). Of the 95 participants who completed the 36-month follow-up, 64% and 56% maintained satisfactory ejaculation control at 24 and 36 months postintervention, respectively.

BACKGROUND: Lichenoid keratosis is a benign cutaneous lesion exhibiting many clinical faces and different dermoscopic features. OBJECTIVE: This study aims to determine the pattern of different clinical subtypes of lichenoid keratosis and to establish whether there is any correlation between the clinical variants of lichenoid keratosis and their dermoscopic appearance. METHODS: We retrospectively analyzed the medical records and clinical database of patients who had received a histological diagnosis of lichenoid keratosis. Based on the literature review and the clinical-dermoscopic features of lichenoid keratosis, we divided the lesions into 6 clinical subtypes to evaluate potential correlations between clinical and dermoscopic features in all subtypes. RESULTS: Fifty-one lesions were included in this clinical study. Preoperatively, only 1.9% of cases were clinically diagnosed as lichenoid keratosis, and the most common misdiagnosis was basal cell carcinoma (52.9%). We identified 6 subtypes of lichenoid keratosis and their corresponding dermoscopic features and clues. CONCLUSION: Since lichenoid keratosis has no pathognomonic dermoscopic clues and it is commonly misdiagnosed as malignant skin neoplasms, such as basal cell carcinoma and melanoma, improving the knowledge of both clinical and dermoscopic variability of lichenoid keratosis may help dermatologists to reduce unnecessary surgery and to reduce health care spending.

INTRODUCTION: Currently, abdominal obesity has reached an epidemic stage and obesity represents an important challenge for worldwide health authorities. Epidemiologic studies have demonstrated that the stone risk incidence increases with Body Mass Index, through multiple pathways. Metabolic syndrome and diabetes are associated with an increased renal stones disease incidence. The aim of this systematic review was to investigate the prevalence, morbidity, risk factors involved in the association between obesity and urolithiasis. EVIDENCE ACQUISITION: The search involved finding relevant studies from MEDLINE, EMBASE, Ovid, the Cochrane Central Register of Controlled Trials, CINAHL, Google Scholar, and individual urological journals between January 2001 and May 2017. The inclusion criteria were for studies written in the English language, reporting on the association between obesity and urinary stones. EVIDENCE SYNTHESIS: The underlying pathophysiology of stone formation in obese patients is thought to be related to insulin resistance, dietary factors, and a lithogenic urinary profile. Uric acid stones and calcium oxalate stones are observed frequently in these patients. Insulin resistance is thought to alter the renal acid-base metabolism, resulting in a lower urine pH, and increasing the risk of uric acid stone disease. Obesity is also associated with excess nutritional intake of lithogenic substances and with an increase in urinary tract infection incidence. Recent studies highlighted that renal stone disease increases the risk of myocardial infarction, progression of chronic kidney disease, and diabetes. Contemporary, bariatric surgery has been shown to be associated with hyperoxaluria and oxalate nephropathy. Certainly, the many health risks of obesity, including nephrolithiasis, will add more burden on urologists and nephrologists. CONCLUSIONS: Obesity related nephrolithiasis seems to necessitate weight loss as primary treatment, but the recognition of the associated complications is necessary to prevent induction of new and equally severe medical problems. The optimal approach to obesity control that minimizes stone risk needs to be determined in order to manage obesity-induced renal stones disease.

AIMS: OnabotulinumtoxinA (onaBNTa) for treating neurogenic detrusor overactivity (NDO) is widely used after its regulatory approval in adults. Although the administration of onaBNTa is still considered off-label in children, data have already been reported on its efficacy and safety. Nowadays, there is a lack of standardized protocols for treatment of NDO with onaBNTa in adolescent patients in their transition from the childhood to the adult age. With the aim to address this issue a consensus panel was obtained. METHODS: A panel of leading urologists and urogynaecologists skilled in functional urology, neuro-urology, urogynaecology, and pediatric urology participated in a consensus-forming project using a Delphi method to reach national consensus on NDO-onaBNTa treatment in adolescence transitional care. RESULTS: In total, 11 experts participated. All panelists participated in the four phases of the consensus process. Consensus was reached if ≥70% of the experts agreed on recommendations. To facilitate a common understanding among all experts, a face-to-face consensus meeting was held in Rome in march 2015 and then with a follow-up teleconference in march 2017. By the end of the Delphi process, formal consensus was achieved for 100% of the items and an algorithm was then developed. CONCLUSIONS: This manuscript represents the first report on the onaBNTa in adolescents. Young adults should be treated as a distinct sub-population in policy, planning, programming, and research, as strongly sustained by national public health care. This consensus and the algorithm could support multidisciplinary communication, reduce the extent of variations in clinical practice and optimize clinical decision making.

OBJECTIVE: To investigate the correlation of a history of lower urinary tract symptomatology during childhood with lower urinary tract dysfunction in young adult women. SUBJECTS AND METHODS: This was a multicentre, prospective, case-control study conducted between April 2013 and November 2015. A total of 300 women, aged 18-40 years, participated. The case group comprised women attending urogynaecology clinics for various lower urinary tract complaints and the control group was recruited from a healthy population. Exclusion criteria were designed to avoid common causes of lower urinary tract dysfunction and symptoms and included diabetes mellitus, neurological disease and pelvic inflammatory disease. All women completed a self-administered 77-item questionnaire, exploring childhood urological and bowel history, as well as current urological, bowel and sexual symptoms. Statistical analysis was performed using chi-squared and Fisher's exact tests to compare categorical variables. Multivariate logistic regression models were fit for the prediction of the adult outcomes, incorporating as explanatory variables all those that showed a significant P value in bivariate analysis. P values < 0.05 were considered statistically significant. RESULTS: Women with childhood urinary voiding and storage symptoms had a higher prevalence of these symptoms in adult life compared with women without such history. Women with urinary tract infections (UTIs) during childhood had a higher incidence of adult UTIs compared with women without this problem in childhood. CONCLUSIONS: Lower urinary tract dysfunction in childhood seems to 'persist' in young adult life but the implications of this finding in clinical practice need to be defined in future studies.

The most common subtype of renal cell carcinoma (RCC) is clear cell RCC (ccRCC). It accounts for 70-80% of all renal malignancies representing the third most common urological cancer after prostate and bladder cancer. The identification of non-invasive biomarkers for the diagnosis and responsiveness to therapy of ccRCC may represent a relevant step-forward in ccRCC management. The aim of this study is to evaluate whether specific miRNAs deregulated in ccRCC tissues present altered levels also in urine specimens. To this end we first assessed that miR-21-5p, miR-210-3p and miR-221-3p resulted upregulated in ccRCC fresh frozen tissues compared to matched normal counterparts. Next, we evidenced that miR-210-3p resulted significantly up-regulated in 38 urine specimens collected from two independent cohorts of ccRCC patients at the time of surgery compared to healthy donors samples. Of note, miR-210-3p levels resulted significantly reduced in follow-up samples. These results point to miR-210-3p as a potential non-invasive biomarker useful not only for diagnosis but also for the assessment of complete resection or response to treatment in ccRCC management.
RESUMO
PURPOSE: Interest in the disease-specific psychological well-being of patients with cancer has increased, and it has been estimated that less than half of all patients with cancer are properly identified and subsequently treated for anxiety or depression. The aim of this study is to evaluate psychological distress in uro-oncological patients undergoing different surgeries: radical cystectomy, radical prostatectomy, radical nephrectomy, or transurethral resection (TUR) before the surgery. MATERIALS AND METHODS: We performed a cross-sectional study in consecutively enrolled patients with bladder, kidney, or prostate cancer, scheduled for surgery. Demographic data, socioeconomic status, education level, and diagnoses were recorded. Patients with a previous diagnosis of depression or anxiety were excluded. We evaluated the level of clinically meaningful depression and anxiety assessed by 2 tools: the Hospital Anxiety and Depression Scale (HADS; score ≥8 presence of anxiety and depression; score ≥11 clinical anxiety and depression) and the State-Trait Anxiety Inventory (STAI). To determine variables related to depression and anxiety among the demographic variables, logistic regression analyses were conducted, with P<0.05 considered as statistically significant. RESULTS: A total of 207 patients were recruited, completed the questionnaires and were included in the study. Patients presented a mean age of 70.8 (±10.8) years, 89% were males (n = 184) and 19% of patients presented previous cancer. The majority of patients underwent surgery for bladder tumors (60.4%) and the most common type of surgery was TUR. The most frequent procedures were performed for bladder tumors (60.4%), being TUR the most common type of surgery (52.7%) followed by radical prostatectomy (24.6%). Mean STAI-State score was 19.3 (±10.3), and mean STAI-Trait score was 18.4 (±11.9) points. Clinical levels of anxiety and depression (HADS ≥ 11 points) were found in 19 (9.8%) and 7 (3.6%) cases. And HADS anxiety 8 to 10 points was present in 14.5% (n = 28) and HADS depression 8 to 10 points in 5.7% (n = 11) of the sample, representing presence of psychological distress. Female patients showed a higher level of anxiety and STAI-Trait compared to males. CONCLUSION: The present results show that our patients had lower levels of anxiety and depression than those described in the literature. Sex, tumor type, and surgical approach were significantly related to psychological distress in patients undergoing surgery for urological cancer. Females and patients with kidney tumor and patients undergoing radical nephrectomy presented higher levels of anxiety. Patients with radical cystectomy showed a higher level of STAI-State compared with other surgeries.

BACKGROUND: The abuse of antimicrobical drugs has increased the resistance of microorganisms to treatments, thus to make urinary tract infections (UTIs) more difficult to eradicate. Among natural substances used to prevent UTI, literature has provided preliminary data of the beneficial effects of D-mannose, N-acetylcysteine, and Morinda citrifolia fruit extract, due to their complementary mechanism of action which contributes respectively to limit bacteria adhesion to the urothelium, to destroy bacterial pathogenic biofilm, and to the anti-inflammatory and analgesic activity. The purpose of this study was to compare the administration of an association of D-mannose, N-acetylcysteine (NAC) and Morinda citrifolia extract versus antibiotic therapy in the prophylaxis of UTIs potentially associated with urological mini-invasive diagnostics procedures, in clinical model of the urodynamic investigation. METHODS: 80 patients eligible for urodynamic examination, 42 men and 38 women, have been prospectively enrolled in the study and randomised in two groups (A and B) of 40 individuals. Patients of group A followed antibiotic therapy with Prulifloxacine, by mouth 400 mg/day for 5 days, while patients of the group B followed the association of mannose and NAC therapy, two vials/day for 7 days. Ten days after the urodynamic study, the patients were submitted to urine examination and urine culture. RESULTS: The follow up assessment didn't show statistical significant difference between the two groups regarding the incidence of UTI. CONCLUSIONS: The association of mannose and NAC therapy resulted similar to the antibiotic therapy in preventing UTIs in patients submitted to urodynamic examination. This result leads to consider the possible use of these nutraceutical agents as a good alternative in the prophylaxis of the UTI afterwards urological procedures in urodynamics.

OBJECTIVES: Monopolar transurethral resection of the prostate (TURP) is the gold standard surgical treatment for bothersome moderate to severe lower urinary tract symptoms (LUTS) secondary to benign prostate obstruction. The aim of the study is to compare monopolar versus bipolar TURP focusing on operative and functional outcomes, and evaluating complications with a long-term follow-up. METHODS: From January 2007 to July 2014, a total of 497 patients were randomized and prospectively scheduled to undergo bipolar (251) or monopolar (246) TURP. International prostate symptom score (IPSS), IPSS-Quality of life (QoL), post-void residual and maximum flow rate were assessed preoperatively and postoperatively at 3, 12, 24 and 36 months. Operative time, length of catheterization and hospitalization were all recorded. Complications were classified and reported. RESULTS: All patients completed the 36-month follow-up visit. Perioperative results showed no statistical significance between the two groups in terms of catheterization days, post-void residual, IPSS, IPSS-QoL score. The hospitalization length was found statistically significant in favor of the bipolar group. The 3-, 12-, 24- and 36-month follow-up showed significant and equal improvements in LUTS related to BPO in the two treatment groups. Regarding TURP complications, significant differences were observed in relation to urethral strictures, blood transfusion and TUR syndrome in favor of the bipolar group. CONCLUSIONS: Monopolar and bipolar TURP are safe and effective techniques for BPH management. Bipolar TURP in our prospective study reported the same efficacy of monopolar prostate resection, with a significant reduction of related complications.

PURPOSE: We developed a consensus on best practice in the real-life management of patients with overactive bladder (OAB) with onabotulinumtoxin A (Onabot/A). METHODS: In March 2015, an interdisciplinary conference was convened. Eleven panelists were invited to review the literature, to present their personal experience and to respond to a number of questions from: "when do we propose Onabot/A treatment" to "when do you decide to re-inject a patient?" A summary of findings of the meeting was provided to all panelists for review and approval. RESULTS: The following statements were agreed. Refractory OAB can be defined based on lack of adherence to first- and second-line treatments for OAB regardless of the underlying cause. Onabot/A treatment can be proposed to refractory OAB patients provided they are willing to perform intermittent catheterization if needed. Before treatment, uroflowmetry with post-void residual evaluation is needed to rule out voiding dysfunction, while urodynamics should be done in cases of complicated OAB wet. Urinary tract infection should be ruled out or treated before the injection. The injection can be performed in the endoscopy room, in an out-patient basis, with local anesthesia. Antibiotic prophylaxis should be initiated with oral drugs. A first follow-up visit should be planned 10-15 days after treatment and residual urine checked. Retreatment can be decided on patients' request, when symptoms worsen. CONCLUSIONS: This consensus document provides a guide for the management of refractory OAB patients with Onabot/A in real life. A number of questions about the effectiveness of Onabot/A in real life remain open.

Cholesterol is a main lipid component of sperm cell that is essential for sperm membrane fluidity, capacitation, and acrosomal reaction. Recent data obtained in bovine sperm showed that sperm capacitation is associated to the formation of oxysterols, oxidized products of cholesterol. The aim of this study was to profile oxysterol content in human semen, and to investigate their potential role in sperm pathophysiology. Among the 12 oxysterols analyzed, 25-hydroxycholesterol (25-HC) resulted the most represented in normozoospermic samples, and its concentration positively correlated with spermatozoa number. We detected Cholesterol 25-hydroxylase, the enzyme responsible for 25-HC production, in human spermatozoa at the level of the neck and the post acrosomal area. Upon incubation with spermatozoa, 25-HC induced calcium and cholesterol transients in connection with the acrosomal reaction. Our results support a role for 25-HC in sperm function.

INTRODUCTION: The purpose of this review was to assess the evidence provided by literature regarding the role of detrusor overactivity (DO) in determining urinary incontinence in patients submitted to radical prostatectomy. EVIDENCE ACQUISITION: The research was based on the online PubMed database spanning the period from November 1997 to May 2016. The review was conducted in accordance with the systematic review guidelines provided by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). EVIDENCE SYNTHESIS: A total of twenty-three articles met the eligibility criteria for this systematic review. The eligible studies included a total of 812 patients with a mean number of 36 patients per study (range 29-264). The rate of patients with urodynamic DO after radical prostatectomy and reporting urge urinary incontinence ranged from 3 to 63%. The postradical prostatectomy DO was more likely to occur in patients who already had it preoperatively [OR =2.30, 95% CI: 1.39-3.82; studies 9; participants 419]. However, most representative studies accordingly indicate that intrinsic sphincter deficiency is the most common cause of postprostatectomy incontinence (PPI), considered as the sole responsible factor for such patients' incontinence (88-100% of patients evaluated); the same studies report that isolated bladder dysfunction is uncommon and that it occurs in only 3% of patients. CONCLUSIONS: The review results suggest that DO could be considered as another possible underlying mechanism for PPI. Although sphincter incompetence and weakness are the most common mechanisms related to incontinence after prostatectomy, DO may coexist or be an isolated cause of PPI. Therefore, urodynamic studies are essential to show which is and/or are the exact cause(s) of incontinence in each individual patient after RP.

INTRODUCTION: Pelvic floor disorders (PFDs), which include urinary incontinence, pelvic organ prolapse, sexual dysfunction and gastrointestinal disorders, affect over 20% of adult population. The prevalence and demand for care of PFDs appear to be increasing more quickly than would be expected from simple population growth, creating substantial physical and emotional distress and a large financial burden. Suitable diagnostic tools are necessary to investigate these problems. The aim of this article is to list Symptom and Quality of Life questionnaires [briefly identified as patient-reported outcomes (PROs)] formally validated into the Italian language to provide Italian clinicians and researchers a tool for the assessment of pelvic area dysfunctions in our country. A synthetic key points summary concerning concepts behind Symptom and Quality of Life Questionnaires will be also provided. METHODS: PubMed/MEDLINE databases and websites were used to identify Italian-validated questionnaires for PFDs. Once identified, the possibility to get a copy of the questionnaire was verified and steps to obtain it are reported in the table. RESULTS: Questionnaires validated into the Italian language, for diagnosis and overall management of common urinary, vaginal, sexual and bowel conditions, are listed in the table. CONCLUSIONS: This format is intended to serve as a tool to promote appropriateness in PROs adoption while investigating PFDs in Italian patients.

INTRODUCTION: Benign prostatic hyperplasia (BPH) resulting in lower urinary tract symptoms (LUTS) is a widespread disease that strongly interferes with the quality of life (QoL) of elderly males. It represents a real clinical and socio-economic problem may be due to the lack of a diagnostic, therapeutic and care pathway (DTCP) tool for LUTS/BPH that considers elderly people population in its whole complexity. The aim of this study was to evaluate the clinical effectiveness of the proposed DTCP LUTS/BPH tool. METHODS: This prospective study was conducted on 278 patients over 75 years old with non-neurogenic LUTS recruited from February to July 2014 by 10 general practitioners (GP) and two assisted sanitary residences (ASR). Only five GPs and one ASR were provided with the complete DTCP LUTS/BPH tool to create two different groups of patients: group A (138 patients) was treated without the aid of the DTCP; group B (140 patients) was treated according to the DTCP. RESULTS: At 1 year of follow-up, the patients of Group B compared with Group A achieved a greater and significant mean reduction in the questionnaires score (International Prostate Symptom Score, Quick prostate test and QoL) linked to a higher increase in the flowmetry parameters (Qmax) and a lower postvoid residual. Furthermore, in Group B compared to Group A, a greater improvement of hydronephrosis, creatinine values and erectile dysfunction (ED) were obtained at 1 year of follow-up. CONCLUSION: The encouraging results obtained from this study are significant and support the use of this diagnostic, therapeutic and care tool (DTCP) as the ideal pathway management for elderly men with LUTS associated to BPH and ED. Further studies with greater number of elderly subjects and long-term follow-up are needed to confirm DTCP utility in the clinical management of LUTS/BPH and ED.
