The waiting time for prostate cancer treatment in Italy: analysis from the Pros-IT CNR study

BACKGROUND

Prostate cancer (PCa) is the second most common neoplasm in male patients. To date, there's no certain indication about the maximum waiting time (WT) acceptable for treatment beginning and the impact on oncological and functional outcomes has not been well established.

METHODS

Data from the National Research Council PCa monitoring multicenter project in Italy (Pros-IT CNR) were prospectively collected and analyzed. WT was defined as the time from the bioptical diagnosis of PCa to the first treatment received. Patients were divided in two groups, using a time frame of 90 days. Quality of life was measured through the Italian version of the University of California Los Angeles-Prostate Cancer Index (UCLA-PCI) and of the Short-Form Health Survey (SF-12). The occurrence of upgrading, upstaging, presence of lymph node metastasis and positive surgical margins at the final histopathological diagnosis, and PSA at 12 months follow-up were evaluated.

RESULTS

The overall median WT was 93 days. The logistic multivariable model confirmed that age, being resident in Southern regions of Italy and T staging at diagnosis were significantly associated with a WT >90 days. At 6 months from diagnosis the mean SF-12 score for the emotionalpsychological component was significantly lower in WT ≥ 90 days group (p=0.0428). Among patients treated with surgical approach, no significant differences in oncological outcomes were found in the two groups.

CONCLUSIONS

In our study age, clinical T stage and provenance from Southern regions of Italy are associated with a WT > 90 days. WT might have no impact on functional and oncological outcome.

Long-term follow-up after percutaneous pulmonary valve implantation: sustained clinical benefit with evidence of persistent biventricular reverse remodeling and improved global performance

Background

Patients with native or post-surgical right ventricular outflow tract (RVOT) dysfunction often require several re-interventions. Percutaneous pulmonary valve implantation (PPVI) has recently been proposed as an attractive alternative to surgery, but there is still lack of data on long-term results.

Aim

To determine the long-term outcome after PPVI and to investigate whether clinical benefit and cardiac performance improvement is achieved after the procedure.

Methods and results

Seventy-eight patients (mean age 31.75±11.7) undergoing PPVI between April 2007 and July 2017 at Royal Brompton Hospital were retrospectively included in the study. The median follow-up was 6.1 years (2.1–11.2). Overall survival was 90.8%±4.1 at 6 years and 85%±5.9 at 11 years with freedom from valve failure (defined as either severe stenosis or regurgitation) of 87.6%±5 at 6 years of follow-up. Annual reintervention rate was 3.2% (95% CI 1.6–5.5). Infective endocarditis was a major concern with annual incidence rate of 1.6% (95% CI 0.5–3.4) and 50% of adverse outcome. Male sex (HR 3.2, 95% CI 1.3–7.9, p=0.013), age at procedure>50 years (HR 4.7, 95% CI 1.5–15.1, p=0.01) and residual mean gradient>25 mmHg at immediate postprocedural echo (HR 4.6, 95% CI 1.6–13.5%, p=0.006) were independently associated to the composite endpoint (including death, re-intervention, valve failure and arrhythmia). At latest follow-up, significant NYHA class (Pre Vs 6.1yrs Post p<0.0001) and cardiopulmonary test results improvement (peakVO2 p=0.01) and arrhythmic burden reduction (p=0.002) were found. Both cardiovascular magnetic resonance (CMR) and serial echocardiograms showed biventricular reverse remodeling (Pre Vs 1.3yrs Post CMR: RVEDVi p=0.0002, RVESVi p=0.0012, LVEDVi p=0.028). Furthermore, speckle tracking assessments demonstrated significant improvement of RV free wall GLS (Pre Vs 6.4yrs Post p=0.03) and LV GLS (p=0.01) at long-term. Moreover, concomitant improvement of RV relaxation properties was suggested by echo evidence of right atrial (RA) reverse remodeling (Pre Vs 6.4yrs Post RA area p=0.0001), increased RA strain (p=0.0005) and reduction of the patients with restrictive RV physiology (p<0.0001).

Conclusion

PPVI is a reliable alternative to surgery with long-lasting favourable clinical effects associated with significant and persistent structural biventricular reverse remodeling and global systolic and diastolic functional improvement. Valve failure and infective endocarditis remain major complications during follow-up. Older and male patients and those with residual transvalvular gradients immediately post procedure are at higher risk of adverse clinical events, thus suggesting that re-intervention should be anticipated and that complete relief of RVOT obstruction should be pursued.

Tamsulosin plus a new complementary and alternative medicine in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia: Results from a retrospective comparative study

BACKGROUND

We aimed to compare the efficacy of tamsulosin 0.4 mg once a day alone and the combination therapy involving tamsulosin 0.4 mg once a day plus the complementary and alternative medicine consisting of vitamins (C and D), herbal products (Cucurbita maxima, Capsicum annum, Polygonum capsicatum) and amino acid L-Glutamine bid in patients with lower urinary tract symptoms related to benign prostatic hyperplasia (LUTS/BPH).

METHODS

We performed a retrospective matched paired comparison. The clinical records of LUTS/BPH patients who underwent medical therapy with tamsulosin 0.4 mg/day plus the complementary and alternative medicine consisting of vitamins (C and D), herbal products (Cucurbita maxima, Capsicum annum, Polygonum capsicatum) and amino acid L-Glutamine bid between January 2019 to September 2019 were reviewed (Group 1). These patients were compared in a 1:1 fashion with LUTS/BPH patients who underwent therapy with tamsulosin 0.4 mg/day alone (Group 2). Total, storage, voiding and Quality of Life (QoL) international prostate symptom (IPSS) score, as well as overactive bladder (OAB)-v8 score and treatment- related adverse events recorded at 40 days follow-up in both groups were compared.

RESULTS

At 40 days follow-up mean total, storage, voiding and QoL IPSS sub-scores as well as OAB-v8 score significantly improved in both groups. Intergroup comparison showed statistically significant lower mean total IPSS score (11.6 vs 12.4, p = 0.04) mean storage IPSS sub-score (6.5 vs 7.5, p = 0.01), and mean OAB v8 score (16.7 vs 18.8, p = 0.03) in patients in the Group 1.

CONCLUSIONS

The combination of tamsulosin 0.4 mg/die plus the complementary and alternative medicine consisting of vitamins (C and D), herbal products (Cucurbita maxima, Capsicum annum, Polygonum capsicatum) and amino acid LGlutamine bid provides statistically significant advantages in terms of storage LUTS improvements in patients with LUTS/BPH compared to tamsulosin 0.4 mg/day alone. These findings are preliminary and further prospective studies on a greater number of patients are needed to confirm it.

A case of incidentally discovered solitary fibrous tumor of the kidney: A case study

Solitary fibrous tumor (SFT) is a rare neoplasm of mesenchymal origin. The kidney represents an unusual location for SFT and the diagnosis and treatment of renal SFT remains challenging. The present study reports the case of a right kidney SFT incidentally discovered in a 52-year old woman. Radiological findings from computed tomography and magnetic resonance imaging were not specific but highly suspect for a malignant neoplasm. The definitive diagnosis relied on histological examination and immunohistochemical staining for CD34 and signal transducer and activator of transcription 6.

Short- and Long-Term Evaluation of Renal Function after Radical Cystectomy and Cutaneous Ureterostomy in High-Risk Patients

Deterioration of renal function has been reported after radical cystectomy (RC) with urinary diversion. We investigated renal function changes in elderly bladder cancer (BCa) patients who underwent RC with cutaneous ureterostomy (CU) urinary diversion. We performed a retrospective, observational study. BCa patients aged ≥75 with an American Society of Anesthesiologists (ASA) class greater than II were included. Glomerular filtration rate (GFR) was the main outcome measure. GFR values were recorded preoperatively, at discharge, at 6-month follow-up, and yearly up to 60 months. A total of 70 patients with a median age of 78.0 years were identified. Median preoperative GFR was 74.3 mL/min/1.73 m2 and declined significantly to 54.6 mL/min/1.73 m2 after 6 months (p < 0.001). A gradual GFR decline was observed thereafter, reaching a median value of 46.2 after 60 months. Preoperative GFR and acute kidney injury were significant predictors of fast deterioration of GFR and of 25% deterioration of GFR after 12 months. Elderly BCa patients with high comorbidity rates undergoing RC with CU should be carefully informed about the risk of GFR deterioration and the need for adequate monitoring.

Perceptions, Expectations, Preferences, and Attitudes Toward Premature Ejaculation, Its Diagnosis and Topical Treatment with Fortacin™ Spray: Results from an Expert Panel Discussion

INTRODUCTION

Premature ejaculation (PE) represents the most prevalent male sexual issue. Before beginning treatment, it is essential to discuss the patient's expectations thoroughly.

METHODS

Herein, we report the results of an expert panel discussion about perceptions, expectations, preferences, and attitudes towards PE, its diagnosis and treatment. The panel took place in October 2019 and involved 30 Italian urologists experienced in the management of male sexual dysfunction. It aimed at investigating physicians' points of view about selected aspects of PE management which emerged during the counselling of PE patients over the previous two years. Treatment-related questions were mainly focused on topical treatment with Fortacin™.

RESULTS

Overall, 83.3% of those interviewed declared that most of their patients perceive PE as a bother rather than a disease. The percentage of urologists interviewed perceived that improved subjective control over ejaculation and prolonged intravaginal ejaculatory latency time (IELT) as the main benefit expected by the majority of their patients was 56.5% and 10%, respectively. Eighty percent of urologists reported on-demand regimen as the dosage modality preferred by the majority of their patients and half of them reported the topical route to be the way of administration preferred in most cases. Moreover, 73.3% of urologists reported that adherence to treatment was higher in patients undergoing topical treatment. Finally, 80% of urologists perceived Fortacin to be efficacious in patients with acquired PE and 70% of them perceived its efficacy to be independent from IELT.

DISCUSSION

Most patients perceive PE as a bother rather than a disease and mainly advocate an improved control over ejaculation. Fortacin is perceived as efficacious in patients with acquired PE, and independent from IELT.

The urothelium, the urinary microbioma and men LUTS: a systematic review

INTRODUCTION

The pathophysiology and management of male patients with lower urinary tract symptoms (LUTS) is still a matter of debate. In the past few years, the urothelium and the urinary microbiota represented important areas of research to improve the understanding and management of these patients. Aim of the present review was to summarize the available data on the urothelium and the microbiota related to male LUTS.

EVIDENCE ACQUISITION

A National Center for Biotechnology Information (NCBI) PubMed search for relevant articles published between January 2000 and December 2019 was performed using the medical subjects heading "urothelium," "microbioma," "microbiota," "urobioma," "urobiota," "benign prostatic hyperplasia," "benign prostatic enlargement," "lower urinary tract symptoms," "lower urinary tract dysfunction," "men," "male," "overactive bladder," "receptors." Exclusion criteria included: animal studies and studies on muscarinic and adrenergic pathways.

EVIDENCE SYNTHESIS

The urothelium has been recently evaluated in humans to evaluate new possible markers and pathways. New possible targets for the treatment of male LUTS include the neural growth factor, the cannabinoid, the vanilloid and the ATP pathways. However, studies in humans are still needed to elucidate the exact role of these pathways in the management of male patients with LUTS. The available evidence on the urinary microbioma in male is poor. Standing to the available, urinary microbioma is evident in healthy urine in males. Moreover, the urinary microbioma varies depending on the method of collection, sexually transmitted disease status, inflammation and urinary symptoms. A possible role of probiotics in the management of LUTS in women has been proposed and may have a role in male patients as well.

CONCLUSIONS

The urothelium and the urinary microbiota are still poorly studied in men with LUTS. Most of the evidence and the hypothesis on the relationship between urothelium/urinary microbiota and LUTS comes from animal/in-vitro evidence while clinical trials are lacking. These pathways seem interesting even in LUTS pathogenesis in men but their possible role as a new therapeutic target is still an open debate.

Endovascular therapy for erectile dysfunction: current knowledge and future perspectives

Erectile dysfunction (ED) is defined as the inability to attain or maintain penile erection sufficient for successful sexual intercourse. ED carries a notable influence on quality of life, with significant implications for family and social relationships. Because atherosclerosis of penile arteries represents one of the most frequent causes of ED, patients presenting with it should always be investigated for potential coexistent coronary or peripheral disease. Up to 75% of patients with ED have a stenosis of the iliac-pudendal-penile arteries, supplying perfusion of the male genital organ. Recently the potential treatment of this pathological condition by percutaneous approaches has emerged with good angiographic results and with a significant improvement in symptoms and quality of life. This review will focus on the normal anatomy and physiology of erection, the pathophysiology of ED, the relation between ED and cardiovascular diseases and, lastly, on new treatment modalities aimed at restoration of normal erectile function.

Sperm recovery and ICSI outcomes in men with non-obstructive azoospermia: a systematic review and meta-analysis

BACKGROUND

Factor affecting sperm retrieval rate (SRR) or pregnancy rates (PR) after testicular sperm extraction (TESE) in patients with non-obstructive azoospermia (NOA) have not been systematically evaluated. In addition, although micro-TESE (mTESE) has been advocated as the gold standard for sperm retrieval in men with NOA, its superiority over conventional TESE (cTESE) remains conflicting.

OBJECTIVE AND RATIONALE

The objective was to perform a meta-analysis of the currently available studies comparing the techniques of sperm retrieval and to identify clinical and biochemical factors predicting SRR in men with NOA. In addition, PRs and live birth rates (LBRs), as derived from subjects with NOA post-ICSI, were also analysed as secondary outcomes.

SEARCH METHODS

An extensive Medline, Embase and Cochrane search was performed. All trials reporting SRR derived from cTESE or mTESE in patients with NOA and their specific determinants were included. Data derived from genetic causes of NOA or testicular sperm aspiration were excluded.

OUTCOMES

Out of 1236 studies, 117 studies met the inclusion criteria for this study, enrolling 21 404 patients with a mean age (± SD) of 35.0 ± 2.7 years. cTESE and mTESE were used in 56 and 43 studies, respectively. In addition, 10 studies used a mixed approach and 8 studies compared cTESE with mTESE approach. Overall, a SRR per TESE procedure of 47[45;49]% (mean percentage [95% CI]) was found. No differences were observed when mTESE was compared to cTESE (46[43;49]% for cTESE versus 46[42;49]% for mTESE). Meta-regression analysis demonstrated that SRR per cycle was independent of age and hormonal parameters at enrolment. However, the SRR increased as a function of testis volume. In particular, by applying ROC curve analysis, a mean testis volume higher than 12.5 ml predicted SRR >60% with an accuracy of 86.2% ± 0.01. In addition, SRR decreased as a function of the number of Klinefelter's syndrome cases included (S = -0.02[-0.04;-0.01]; P < 0.01. I = 0.12[-0.05;0.29]; P = 0.16). Information on fertility outcomes after ICSI was available in 42 studies. Overall, a total of 1096 biochemical pregnancies were reported (cumulative PR = 29[25;32]% per ICSI cycle). A similar rate was observed when LBR was analysed (569 live births with a cumulative LBR = 24[20;28]% per ICSI cycle). No influence of male and female age, mean testis volume or hormonal parameters on both PR and LBR per ICSI cycle was observed. Finally, a higher PR per ICSI cycle was observed when the use of fresh sperm was compared to cryopreserved sperm (PR = 35[30;40]%, versus 20[13;29]% respectively): however, this result was not confirmed when cumulative LBR per ICSI cycle was analysed (LBR = 30[20;41]% for fresh versus 20[12;31]% for cryopreserved sperm).

WIDER IMPLICATIONS

This analysis shows that cTESE/mTESE in subjects with NOA results in SRRs of up to 50%, with no differences when cTESE was compared to mTESE. Retrieved sperms resulted in a LBR of up to 28% ICSI cycle. Although no difference between techniques was found, to conclusively clarify if one technique is superior to the other, there is a need for a sufficiently powered and well-designed randomized controlled trial to compare mTESE to cTESE in men with NOA.

Hexaminolevulinate blue light cystoscopy (Hal) assisted transurethral resection of the bladder tumour vs white light transurethral resection of the bladder tumour in non-muscle invasive bladder cancer (NMIBC) : a retrospective analysis

BACKGROUND

Bladder cancer is the eleventh most commonly diagnosed cancer worldwide. The recurrence rate of this cancer can be very high, up to 45%. Photodynamic diagnosis (PDD) is more sensitive than standard procedures for the detection of malignant tumours. The aim of the study was to evaluate oncological outcomes in white light TURB (WL-TURB) and hexaminolevuninate blue light TURB (Hal-TURB).

PATIENTS AND METHODS

This was a retrospective longitudinal single-center study. In the period between January 2016 and October 2016 WL-TURB was the only therapeutic option available. From November 2016 until April 2017 all TURBs were fluorescence-guided (Hal-TURB). Kaplan-Meier curves have been used to estimate recurrence free survival rates.

RESULTS

One hundred and eleven patients underwent Hal- TURB and 137 underwent WL-TURB. Recurrence rate after 12 months was 19.8% (22 out of 111 patients) and 37.2% (51 out of 137 patients) in HAL-group and WL-group respectively (p < 0.01). The recurrence-free period was longer in HAL-group rather than WL-group (8.9 months vs 7.3 months, p < 0.05). Moreover, the recurrence rate during the first 6 months was 3.7% in patients who underwent HAL-TURB and 16% in those who received WL-TURB (p < 0.01).

CONCLUSION

The results of the study show that recurrence-free survival was longer in patients undergoing HAL-TURB compared to the patients who received standard WL-TURB.

Clinical Efficacy of Silodosin in Patients with Severe Lower Urinary Tract Symptoms Related to Benign Prostatic Obstruction: A Pooled Analysis of Phase 3 and 4 Trials

We performed a post hoc analysis of data from phase 3 and 4 studies to evaluate the efficacy of silodosin 8mg in patients with severe lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). The presence of two or more of the following criteria was adopted to define severity: total International Prostate Symptom Score (IPSS) 20-35, quality of life (QoL) score 5-6, maximum urinary flow <5ml/s or postvoid residual volume ≥100ml, and prostate volume ≥50ml. Mean improvements in total (8.1 vs 4.7), storage (3.1 vs 2.0), voiding (5.0 vs 2.7), and QoL (1.3 vs 0.7) IPSS scores were significantly greater for patients receiving silodosin compared to placebo (all p< 0.0001). Mean improvements in total, storage, voiding, and QoL IPSS scores were similar for the severe and not severe LUTS cohorts. In conclusion, silodosin significantly improves symptoms and QoL in all LUTS/BPO patients, including those with severe symptoms. PATIENT SUMMARY: Silodosin improves symptoms and quality of life for patients with severe lower urinary tract symptoms related to benign prostatic obstruction.

Detrusor overactivity and underactivity: implication for lower urinary tract symptoms related to benign prostate hyperplasia diagnosis and treatment

INTRODUCTION

Detrusor underactivity (DUA) and detrusor overactivity (DO) have potential impact on the outcomes of surgery for lower urinary tract symptoms related to benign prostate hyperplasia (LUTS/BPH).

EVIDENCE ACQUISITION

We performed a literature search including studies on humans enrolling patients with preoperative urodynamic evidence of DO and/or DUA undergoing LUTS/BPH surgery. Factors that may influence the outcomes of surgery in these patients were evaluated.

EVIDENCE SYNTHESIS

In patients with DUA mean bladder contractility index improved from +4 to +44.6, mean total International Prostate Symptom Score (IPSS) improved from -3 to -19.5 points, mean maximum urinary flow (Q<inf>max</inf>) improved from +1.4 to +11.7 mL/s, and mean postvoid residual volume (PVR) improved from -16.5 to -736 mL. Older age, lack of obstruction, concomitant DO, lower detrusor contractility and use of transurethral resection of the prostate (TURP) or photovaporization (PV) instead of Holmium laser enucleation of the prostate (HoLEP) were associated with worse outcomes. In patients with DO, the percentage of DO resolution ranged from 57.1% to 83.3%. Mean total IPSS, Q<inf>max</inf>, and PVR variations ranged from +0.9 to -15.7 points, from -0.2 mL/s to +14 mL/s, and from -19.6 to -202.5 mL, respectively. Older age, lack of obstruction, terminal DO, low maximum cystometric capacity, early and high amplitude DO, and use of transurethral prostate incision instead of TURP or open adenomectomy were associated with worse outcomes.

CONCLUSIONS

In patients with DUA or DO, surgery for LUTS/BPH provides overall good results. However, a number of factors can affect these outcomes.

Second cycle of intralesional Collagenase Clostridium histolyticum for Peyronie's disease using the modified shortened protocol: Results from a retrospective analysis

The purpose of this study was to evaluate the effectiveness and safety of the second cycle of Collagenase Clostridium histolyticum injections using the modified shortened protocol. We performed a retrospective analysis on patients who had already undergone the first cycle of injections using the modified shortened protocol and requested more injections to improve the remaining curvature. The International Index of Erectile Function, the Peyronie's Disease Questionnaire and the Global Assessment of Peyronie's Disease questionnaire were self-administered to all patients. All the parameters were recorded at baseline, after the first cycle and after the second cycle of injections. All adverse events were recorded. Seventeen patients completed two cycles of injections. All patients had a reduction of the initial curvature after the first cycle, with a mean improvement of 17.4° (27.4%). After the second cycle, the reduction of the curvature was 7.9° (17.1%), and 29.4% of patients had no further improvement. No severe side effect was recorded. The results of the present study confirm the effectiveness and safety of the modified shortened protocol of Collagenase C. histolyticum injections for Peyronie's disease. However, the second cycle of three injections may be less effective, and patients may not be completely satisfied.

P989 Speckle tracking echocardiography for assessment of baseline myocardial dysfunction and remodelling following tricuspid valve surgery in adults with Ebsteins anomaly

Funding Acknowledgements

Swedish Heart-Lung Foundation, Swedish Society of Medicine, Swedish Heart Association, Skåne University Hospital, Region Skåne, and Lund University

Background

Ebstein’s anomaly (EA) is due to failure of tricuspid valve (TV) delamination and often associated with RV myopathy. Conventional echocardiographic measurements of systolic ventricular function such as LV EF, and tricuspid annular plane systolic excursion/fractional area change (TAPSE/FAC) are load dependent and may therefore not reflect true myocardial function. Speckle tracking echocardiography (STE) evaluates more subtle myocardial deformation globally and on a regional level. Due to being load independent STE may be the most appropriate way to determine myocardial effects of EA intervention for which data in adults are limited.

Purpose

We aimed to study biventricular myocardial function before and after tricuspid valve repair/replacement (TVR) in adults with EA with both STE-derived peak systolic global and regional longitudinal strain (GLS; RLS) and conventional echocardiography.

Methods

A retrospective study of 18 EA patients (55.6% women), who underwent surgical TV repair/replacement (3/15; age at operation: 39 ± 12y) between 2005-2017 was performed. 2D longitudinal strain and conventional assessment of LV and RV function were assessed pre-TVR, and at 1- and 2-years post-TVR. LV and right ventricular (RV) segments were graded for STE assessment feasibility (0-3: no visualisation-optimal). Segments scored 0 were excluded from the strain analysis. Biventricular GLS and RLS were measured by semi-automated tracking.

Results

Compared to pre-TVR, LVEF improved after TVR at 1 year (Table 1, p = 0.03), but this was not sustained and returned to baseline after 2 years. TAPSE declined 1-year post-TVR with no further change after 2 years (Table 1). RVFAC did not differ pre- and post-TVR. LV GLS and RLS were low pre-TVR without amelioration at 1 or 2 years after TVR (Table 1). RV GLS deteriorated from pre-TVR to 1-year post-TVR with only minor amelioration after 2 years (p = 0.03). RV RLS showed a decrease at basal and mid free wall 1-year post-TVR, and at basal free wall, the mid free wall and the mid septum after 2 years (Table 1). Only, one segment improved in RLS from 1 to 2-year post-TVR (p = 0.03). Least feasible segments were LV apical lateral (both pre- and post-TVR), RV mid (pre-TVR and 1y post-TVR) and apical free wall (pre-TVR, 1y and 2y post-TVR) (all, median score 1).

Conclusions

In adult patients with EA, LV GLS was reduced before and unchanged after surgery despite preserved EF, and LVEF initially improved but returned to baseline values with time. Although TV surgery reduced the degree of TV regurgitation and RV size, it might have unmasked a potential RV myocardial disease. Both RV longitudinal strain and TAPSE were reduced 1 and 2 years post-TVR with limited recovery of RV longitudinal strain, but not of TAPSE, between 1 and 2 years post-TVR. Speckle tracking echocardiography (STE) is a feasible and a sensitive, load independent method in detecting biventricular myocardial dysfunction and time course of remodelling after surgery.

P1598 Ruptured Sinus of Valsalva: clinical and echocardiographic features at presentation and long-term results after surgical and percutaneous repair

Background

Rupture of Sinus of Valsalva (rSOV) is a rare and potentially life-threatening condition often misdiagnosed. Percutaneous device closure has been replacing surgical repair as a treatment of choice. However, long-term outcome is poorly documented.

Methods

Echo database (2001-2019) was searched for patients &gt;16y with rSOV. Clinical data were collected from ACHD database. Marfan Syndrome patients were excluded.

Results

Fifteen patients (42.2y, 10M) were diagnosed with rSOVbetween 1979 and 2019. HF symptoms at initial presentation were reported in 50%. All cases were diagnosed by TTE with finding of high velocity continuous flow from SOV to right heart. Two were initially misdiagnosed as VSD. Digital imaging recordings of 10/15 were available. The aortic root was dilated in 8/10. Four had asymmetrical SOV dilatation. LV and LA were dilated in 7/10 and 9/10. Significant aortic regurgitation was in 4. Two had RVOTO. RVSP was always raised. Echo findings are summarised in the Table.

Mean FU after repair was 10,7y (0,9-39). Ten patients had surgical repair and 5 device closure. Seven had repair of concomitant lesions (4 VSD closure and 3 AVR) at the time of the procedure. One redo device closure was performed. During FU 1 died from Cardiomyopathy. At the latest FU significant improvement in functional class, LV and LA size and RVSP was found.

Conclusion

1107 An unusual vegetation on a prosthetic pulmonary valve

Conclusion

Differential diagnosis of cardiac vegetations is a challenging process including microbological tests, multi modality imaging and clinical reasoning. It is always necessary to consider alternative diagnosis, even when traditional imaging tests seem to suggest infective endocarditis.

Non infective thrombotic endocarditis are a rare form of negative blood culteres endocarditis related to systemic hypercoagulable state (i.e. antiphospholipid syndrome, systemic lupus, behcet syndrome, cancer). Malignancies can be considered an unusual cause of cardiac vegetation and they must be taken into account on differential diagnosis.

P781 Role of serum biomarkers combined with two-dimensional speckle tracking echocardiography for screening of immunotherapy-induced cardiotoxicity

Background

Immune checkpoint inhibitors (ICIs) are a novel class of antineoplastic drugs which have dramatically changed the management of non-small cell lung cancer. ICI-associated cardiotoxicity is rare, but potentially fatal, presenting in most of cases as autoimmune acute myocarditis during the first phase of treatment. However, since an extensive cardiac monitoring is not routinely performed in most immunotherapy trials, the true incidence of ICIs related cardiac effects is largely unknown.

Aim

Aim of our study is to ascertain a possible subclinical cardiac involvement in patients with non-small cell lung cancer treated with ICIs.

Methods

We prospectively recruited 40 patients (13 males; mean age 64.3 ± 8.3 years) starting immunotherapy with PD-1/PDL-1 inhibitors for non-small lung cancer between January and August 2018. Demographic and clinical data were recorded and all patients underwent a standard 12-lead ECG and a transthoracic echocardiogram with assessment of left ventricular global longitudinal strain (LV GLS). Furthermore, blood samples for pro BNP-nt and high sensitivity Troponin T (hsTnT) measurements were collected. Serial assessments were performed before and 1 and 3 months after initiation of immunotherapy.

Results

A history of previous coronary artery disease was documented in eight cases (20%). At follow-up no cardiovascular events were recorded. Compared with baseline, echocardiographic parameters of ventricular function did not significantly changed at 1 and 3 months (LVEF 61 ± 6% at baseline, 61 ± 5% at 1 month, 60,2 ± 5% at 3 months, p =0.1; E/E’at baseline 9.2 ± 3, 9.2 ± 2.8 at 1 month, 9.1 ±3,5 at 3 months, p = 0.2;TAPSE 20 ± 3.4 mm at baseline, 21.3 ± 2.8 mm at 1 month, 20 ± 3.8 mm at 3 months, p =0.1; LV GLS -20.3 ± 3.6% at baseline, -20.8 ± 2.3% at 1 month, -20.6 ± 3% at 3 months; p = 0.4). Analogously, no significant increase in circulating levels of cardiac biomarkers was found with hsTnT &lt;0.015 ng/ml in all patients at baseline, 1 month and 3 months and median proBNP-nt 118 pg/ml (IQR 47-200) at baseline, 171 pg/ml (IQR 91-520) at 1 month, and 182 pg/ml (IQR 78-470) at 3 months, p = 0.9.

Conclusions

In our study no significant clinical or subclinical evidence of myocardial involvement was detected during treatment with ICIs in patients with non-small cell lung cancer, thus suggesting the potential cardiovascular safety of this promising class of antineoplastic drugs.

Treatment of acute diverticulitis with open abdomen technique

AIM

The aim of this study is to highlight our experience about the use of open Abdomen's technique as strategy for the management of complicated colon diverticulitis with a delayed anastomosis or colostomy.

MATERIALS AND METHODS

Thirty patients, with III and IV Hinchey stage, have been undertaken to a surgical procedure with Open Abdomen technique and application of Ab-thera device. A second surgical look was made after 48-72 hours in order to evaluate the possibility to do an anastomosis or colostomy.

RESULTS

No deaths in patients with anastomosis were reported, but one case of leakage at the 8th day and one case of micro pulmonary embolism had been displayed. Elderly patients were discharged between the 15TH /18th day. One patient affected by lymphoma was sent in haematology department for other treatment.

DISCUSSION

Today trend is to treat the diverticular disease with colic and paracolic abscess by a medical therapy and percutaneous drainage under CT scan or ultrasound view. With III and IV of Hinchey scale we perform the resection with anastomosis or colostomy. The open abdomen technique allows the surgeons to make the decision of colostomy or anastomosis in the second surgical look at 48-72 hours after the first treatment with irrigation and aspiration during AB-Thera.

CONCLUSION

The Open Abdomen technique is a valid therapeutic alternative approach for patients with acute diverticulitis disease in III and IV Hinchey grade. This therapeutic approach gives important advantages in patients with delayed colostomy.

Prevalence and risk factors of erectile dysfunction in patients with hepatitis B virus or hepatitis C virus or chronic liver disease: results from a prospective study

Background Approximately 300million people are affected by hepatitis B virus (HBV) or hepatitis C virus (HCV) infection worldwide. Erectile dysfunction (ED) is a frequent condition that impairs the quality of life and can be associated with several chronic disorders (type 2 diabetes mellitus, atherosclerosis, depression). Few studies have evaluated the prevalence of ED in patients with HBV and HCV chronic infection. The aim of this study was to evaluate the prevalence and the risk factors of ED in a cohort of patients with HBV or HCV-related chronic liver diseases.

METHODS

Consecutive patients with HCV and HBV chronic infection were enrolled.

RESULTS

In total, 89 out (49 with cirrhosis, 21 with HBV and 68 with HCV infection) were included in this study. ED was diagnosed in 76.4% of patients. The use of phosphodiesterase type 5 inhibitors was reported by 21.3% of patients. Patients with ED were older and had a higher rate of cirrhosis and diabetes mellitus compared with patients without ED. At multivariate analysis, diabetes mellitus and stage of liver disease (cirrhosis vs chronic hepatitis) were the only independent predictors of ED.

CONCLUSION

Due to the high rate of ED in outpatients with viral-related liver disease and the underuse of phosphodiesterase type 5 inhibitors, a larger study focussed on these patients is needed.

Detection of Extraprostatic Extension of Cancer on Biparametric MRI Combining Texture Analysis and Machine Learning: Preliminary Results

RATIONALE AND OBJECTIVES

Extraprostatic extension of disease (EPE) has a major role in risk stratification of prostate cancer patients. Currently, pretreatment local staging is performed with MRI, while the gold standard is represented by histopathological analysis after radical prostatectomy. Texture analysis (TA) is a quantitative postprocessing method for data extraction, while machine learning (ML) employs artificial intelligence algorithms for data classification. Purpose of this study was to assess whether ML algorithms could predict histopathological EPE using TA features extracted from unenhanced MR images.

MATERIALS AND METHODS

Index lesions from biparametric MRI examinations of 39 patients with prostate cancer who underwent radical prostatectomy were manually segmented on both T2-weighted images and ADC maps for TA data extraction. Combinations of different feature selection methods and ML classifiers were tested, and their performance was compared to a baseline accuracy reference.

RESULTS

The classifier showing the best performance was the Bayesian Network, using the dataset obtained by the Subset Evaluator feature selection method. It showed a percentage of correctly classified instances of 82%, an area under the curve of 0.88, a weighted true positive rate of 0.82 and a weighted true negative rate of 0.80.

CONCLUSION

A combined ML and TA approach appears as a feasible tool to predict histopathological EPE on biparametric MR images.

Bipolar endoscopic enucleation versus bipolar transurethral resection of the prostate: an ESUT systematic review and cumulative analysis

PURPOSE

To perform a cumulative analysis of the current evidence on the surgical and functional outcomes of bipolar endoscopic enucleation of the prostate (b-EEP) versus bipolar transurethral resection of the prostate (b-TURP).

METHODS

A systematic review of the literature was performed on PubMed, Ovid^®, and Scopus^® according to Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA Statement). The meta-analysis was conducted using the Review Manager 5.3 software. Parameters of interest were surgical and functional outcomes. Weighted mean difference, and odds ratio with 95% confidence interval were calculated for continuous and binary variables, respectively. Pooled estimates were calculated using the random-effect model.

RESULTS

Fourteen comparative studies were included. No statistically significant difference in terms of overall baseline characteristics was found. b-EEP had higher amount of resected tissue (p < 0.0001), shorter catheter time (p = 0.006), lower Hb drop (p = 0.03), and shorter length of stay (p < 0.0001). Equally, overall post-operative complications were lower (p = 0.01) as well as short (p = 0.04), and long-term complication rate (p = 0.04). There was higher re-intervention rate in the b-TURP group (p = 0.02) whereas b-EEP group had smaller residual prostate volume (p = 0.03), and lower post-operative PSA values (p < 0.00001). At long term, b-EEP presented lower IPSS (p = 0.04), higher Q_max (p = 0.002), and lower PVR (p < 0.00001).

CONCLUSIONS

b-EEP is an effective and safe surgical treatment for BPO. This procedure might offer several advantages over standard b-TURP, including the resection of a larger amount of tissue within the same operative time, shorter hospitalization, lower risk of complications, and lower re-intervention rate. This was submitted to PROSPERO registry: CRD42019126748.

Advantages of Damage Control Strategy With Abdominal Negative Pressure and Instillation in Patients With Diffuse Peritonitis From Perforated Diverticular Disease

Purpose. To evaluate the results of Damage Control Strategy (DCS) in the treatment of generalized peritonitis from perforated diverticular disease in patients with preoperative severe systemic diseases. Methods. All the patients with diffuse peritonitis (Hinchey 3 and 4) and the American Society of Anesthesiologists (ASA) score ≥3 were included and underwent DCS consisting of a 2-step procedure. The first was peritoneal lavage, perforated colon-stapled resection, and temporary abdominal closure with negative pressure wound therapy combined with instillation. The second step, 48 hours later, included the possibility of restoring intestinal continuity basing on local and general patients' conditions. Results. Thirty patients (18 [60%] women and 12 [40%] men, median age 68.5 [range = 35-84] years) were included (18 [60%] ASA III, 11 [36.7%] ASA IV, and 1 [0.03%] ASA V). Seven patients (23.3%) showed sepsis and 1 (3.33%) septic shock. At second surgery, 24 patients (80%) received a colorectal anastomosis and 6 patients (20%) underwent a Hartmann's procedure. Median hospital stay was 18 days (range = 12-62). Postoperative morbidity rate was 23.3% (7/30) and included 1 anastomotic leak treated with Hartmann's procedure. Consequently, at discharge from hospital, 23 patients (76.6%) were free of stoma. Primary fascial closure was possible in all patients. Conclusions. DCS with temporary abdominal closure by negative pressure wound therapy combined with instillation in patients with diffuse peritonitis from complicated diverticulitis could represent a feasible surgical option both in hemodynamically stable and no stable patients, showing encouraging results including a low stoma rate and an acceptable morbidity rate.

Intravesical administration of combined hyaluronic acid and chondroitin sulfate can improve symptoms in patients with refractory bacillus Calmette-Guerin-induced chemical cystitis: Preliminary experience with one-year follow-up

OBJECTIVE

We investigated the efficacy of intravesical instillations of combined hyaluronic acid (HA) and chondroitin sulphate (CS) in patients with bacillus Calmette-Guérin (BCG)-induced chemical cystitis unresponsive to first-line therapies.

PATIENTS AND METHODS

We retrospectively reviewed the clinical records of patients with grade 2 BCG-induced chemical cystitis unresponsive to first line therapeutic options performed according to the International Bladder Cancer Group guidelines who underwent intravesical instillations of HA/CS. Bladder pain, urinary urgency, voiding volume and number of voids/24 hours recorded prior to treatment, at the end of the treatment, at six months and at one-year follow-up were recorded and analyzed.

RESULTS

The records of 20 patients were identified. All patients underwent eight weekly instillations of HA/CS. Mean baseline visual analogue scale (VAS) scores ± Standard Deviation (SD) for urinary urgency and bladder pain were 7.8 ± 0.5 and 7.2 ± 1.0, respectively. Mean number of voids/24 hours ± SD was 15.4 ± 2.3 and mean urine volume per void ± SD was 85.8 ± 21.0 mL. At the end of the treatment, mean VAS scores ± SD for urgency and pain significantly decreased to 4.7 ± 1.1 and 4.2 ± 0.9, respectively (p < 0.05 in both cases). Mean number of voids/24 hours ± SD decreased to 9.6 ± 1.4 (p < 0.05) and mean urine volume per void ± SD significantly increased to 194.1 ± 59.5 mL (p < 0.05). At six months and one-year followup, all outcome measures remained stable.

CONCLUSIONS

Bladder instillations of HA/CS provide significant and durable improvement of bladder pain, urinary urgency, urinary volume per void and urinary frequency in patients with refractory BCG-induced chemical cystitis.

Progressive bladder remodeling due to bladder outlet obstruction: a systematic review of morphological and molecular evidences in humans

BACKGROUND

Bladder outlet obstruction is a common urological condition. We aimed to summarize available evidences about bladder outlet obstruction-induced molecular and morphological alterations occurring in human bladder.

METHODS

We performed a literature search up to December 2017 including clinical and preclinical basic research studies on humans. The following search terms were combined: angiogenesis, apoptosis, bladder outlet obstruction, collagen, electron microscopy, extracellular matrix, fibrosis, hypoxia, histology, inflammation, innervation, ischemia, pressure, proliferation, remodeling, suburothelium, smooth muscle cells, stretch, urothelium.

RESULTS

We identified 36 relevant studies. A three-stages model of bladder wall remodeling can be hypothesized involving an initial hypertrophy phase, a subsequent compensation phase and a later decompensation. Histological and molecular alterations occur in the following compartments: urothelium, suburothelium, detrusor smooth muscle cells, detrusor extracellular matrix, nerves. Cyclic stretch, increased hydrostatic and cyclic hydrodynamic pressure and hypoxia are stimuli capable of modulating multiple signaling pathways involved in this remodeling process.

CONCLUSIONS

Bladder outlet obstruction leads to progressive bladder tissue remodeling in humans. Multiple signaling pathways are involved.

Silodosin 8 mg improves benign prostatic obstruction in Caucasian patients with lower urinary tract symptoms suggestive of benign prostatic enlargement: results from an explorative clinical study

Background

To preliminary investigate the effects of silodosin 8 mg once daily on obstruction urodynamic parameters and subjective symptoms in Caucasian patients with lower urinary tract symptoms suggestive of benign prostatic enlargement.

Methods

We performed a single-center, open-label, single-arm, post-marketing interventional clinical trial. Inclusion criteria were: Caucasian subjects aged ≥50 years waiting to undergo surgery for lower urinary tract symptoms suggestive of benign prostatic enlargement, international prostate symptom total score ≥ 13, international prostate symptom-quality of life score ≥ 3, prostate volume ≥ 30 ml, maximum urine flow rate ≤ 15 mL/s, bladder outlet obstruction index > 40. Eligible subjects received one capsule of silodosin 8 mg once daily for 8 weeks. Invasive urodynamic evaluations were performed at baseline and at 8-weeks follow-up. International prostate symptom questionnaire was administered at baseline, after 4-weeks and 8-weeks of treatment.

Results

Overall, 34 subjects were included. Mean bladder outlet obstruction index significantly decreased from 70.6 to 39.2 and bladder outlet obstruction index class improved in 16 patients (53.3%). Statistically significant improvements of mean total international prostate symptom score, mean storage sub-score, mean voiding sub-score and mean quality of life sub-score were evident after 4-weeks of treatment with further improvements after 8-weeks. At the end of the treatment, all patients declared that their condition improved enough to spare or delay surgery.

Conclusions

Silodosin 8 mg once daily significantly improves benign prostatic obstruction in Caucasian patients with lower urinary tract symptoms suggestive of benign prostatic enlargement waiting for surgery.

Tadalafil versus sildenafil citrate in the treatment of ED: Italian patients’ preferences and explanatory notes

This is an open, multicentre, randomized, crossover study having the aim to evaluate the preference for sildenafil citrate or tadalafil in a population of Italian patients affected by ED, and to compare the efficacy and safety of these two drugs.

Material and Methods.

From October 2003 to November 2004, thirteen Italian centers enrolled ED patients (age >18) being in steady and naïve relation to ED treatment, both through PDE5 inhibitors and any other treatment option. These patients were randomized to sildenafil or tadalafil for 12 weeks, after which they were switched to the alternative treatment for a further 12 weeks. The preference was evaluated through the Treatment Preference Question (TPQ): “During this clinical trial you have taken tadalafil and sildenafil for the treatment of erectile dysfunction. Which medication do you prefer to take for the next 8 weeks of treatment?”. Moreover, patients were asked to express their preference as “strong” or “moderate” and to answer some questions to clarify the reasons behind their preference. SEP and IIEF-EF questionnaires were used for a comparison of efficacy.

Results.

167 patients were enrolled, 144 of whom completed both treatment periods. On being asked the TPQ, 75% of patients (n=108) decided to continue treatment with tadalafil, in particular because it made it possible to have an erection many hours after taking the medication (first or second preference reason for 64.8% of patients), while 25% (n=36) preferred sildenafil (p=0.001). Both drugs improved the IIEF-EF and SEP scores compared to baseline, with a slightly but significantly greater improvement with tadalafil for both parameters.

Conclusions.

Tadalafil and sildenafil are both effective and well tolerated. Most of the patients prefer tadalafil thanks to the possibility of having sexual intercourse many hours after taking the medication.

Incidentally discovered pelvic paraganglioma: A case report

Paragangliomas (PGL) are rare neuroendocrine tumors of the autonomic nervous system originating from paraganglia. Although PGL may arise at any site where physiologic paraganglionic tissue exists, the localization in the small pelvis is extremely rare. PGL may be hormonally active and release surplus catecholamines into the blood or inactive. The asymptomatic cases pose a diagnostic dilemma. We describe the case of an asymptomatic PGL arising in the small pelvis sidewall presenting as an incidentally discovered asymptomatic mass in a male subject.

The Role of the Hydrogen Sulfide Pathway in Male and Female Urogenital System in Health and Disease

SIGNIFICANCE

The endogenous hydrogen sulfide (H₂S) pathway produces an array of biological effects that vary depending on the bodily region. In addition, the H₂S pathway's relevance often changes depending on a healthy or disease state. There is abundant evidence pointing to a key role for this pathway in male and female genito-urinary diseases, suggesting it as a possible target for new therapeutic approaches. Recent Advances: The tissue-specific localization of the H₂S enzymes in the genito-urinary tract has allowed for a better understanding of its role in the body's pathophysiology. Indeed, in humans, cystathionine-γ-lyase (CSE) plays a major role in corpus cavernosum whereas cystathionine-β-synthase (CBS) plays a role in bladder functioning. The prostate epithelium expresses CBS and CSE, but stromal CSE only. In the uterus, up- or downregulation of CBS and CSE varies strongly depending on the female's hormonal cycle or pregnancy.

CRITICAL ISSUES

There is still the need to better define the male and female's sexual hormonal roles in regulating the H₂S pathway, particularly in human pathological conditions. The lack of a correlation between human and animal data should be carefully considered when planning preclinical studies. The unmet need for selective enzymatic inhibitors and the different methodologies for H₂S measurements still represent a critical issue in this research field.

FUTURE DIRECTIONS

It is feasible that the L-cysteine/H₂S pathway can represent an alternative therapeutic target in genito-urinary tract disorders. The research should focus on erectile dysfunction and preeclampsia, characterized by vascular defect, as well as on bladder disorders where the urothelium is compromised. Antioxid.

A rare case of male pelvic squamous cell carcinoma of unknown primary origin presenting as perineal abscess and urethral stenosis

Carcinomas of unknown primary origin (CUP) represent a diagnostic and therapeutic challenge. Squamous cell CUP located in the male pelvis are very rare. We describe a case of a locally advanced squamous cell CUP occurring in the male pelvis presenting as perineal abscess and urethral stenosis and diagnosed by means of transperineal needle biopsy.

A case of highly aggressive anaplastic seminoma of the testis presenting as fungating scrotal lesion

Anaplastic seminoma (AS) is an uncommon histological variant of classical seminoma of the testis and account for 5%-15% of cases. It is poorly described in the scientific literature. We present the case of a 50-years-old homeless man presenting with fever, marked left scrotal hardness and a fungating left scrotal lesion. He underwent left orchiopexy 40 years before. A computed tomography with contrast media showed a suspect testis cancer with scrotal involvment, extensive intralesional necrosis and multiple systemic metastases. A wide excision of the left hemiscrotum including the testis was performed in order to prevent severe local and systemic infectious complications. Histological examination revealed an AS. General conditions showed a rapid deterioration and the patient died on post operative day 10.

Giant endometrial cyst of the liver: a case report and review of the literature

Endometriosis is a benign condition described as the presence of endometrial- like tissue found outside the uterine cavity. Hepatic endometriosis is one of the rarest localization of extrapelvic endometriosis, only 22 cases have been reported in the literature. The preoperative diagnosis of hepatic endometriosis is rather difficult because in about the half of the patient affected they had no history of endometriosis. Moreover radiological images reveal no characteristic findings for hepatic endometriosis. It is often described as cystic mass with or without solid component, difficult to distinguish from hepatic abscess, hematoma, cystoadenoma or malignant neoplasia. We report a case of a 27-year-old female with a large cystic mass involving the left lobe of the liver. The patient underwent laparoscopic exploration and converted to laparotomy for resection of giant hepatic endometriosis.

Prevalence of chronic prostatic inflammation based on clinical diagnostic criteria in a real-practice setting: a nation-wide observational study

BACKGROUND

Chronic prostatic inflammation has a key role in the pathogenesis and progression of benign prostatic hyperplasia (BPH). Thus, the identification of patients with chronic inflammation is mandatory for Urologists. This study investigates which clinical, imaging and laboratory findings are used by Urologists in clinical practice to diagnose BPH and chronic prostate inflammation.

METHODS

This was a multicenter, non-interventional, observational study involving 30 Italian large-volume primary care urology centers. Patients were allocated into four diagnosis group: patients with BPH; patients with BPH and chronic prostate inflammation; patients with chronic prostate inflammation alone; and patients with lower urinary tract symptoms (LUTS) due to other causes.

RESULTS

In total, 6134 patients were enrolled. BPH diagnosis with or without concomitant prostate inflammation was more frequent in older patients, while inflammation alone was prevalent in younger patients. Predictive factors for diagnosis of inflammation in all patients, regardless of age, were normal urinary flow (OR=2.73) and proved in-fection (OR=5.90), while in older patients (>61 years) diagnosis of chronic prostatic inflammation was specifically predicted by higher PSA values (≥4 ng/mL; OR=2.91), normal prostate volume (OR=10.23), mild symptoms (IPSS <8; OR=1.84), presence of intraprostatic calcifications (OR=4.55), and the combination of both infection and calcifications (OR=10.79).

CONCLUSIONS

In daily practice, the presence of chronic prostatic inflammation is underestimated. A stricter application of established diagnostic criteria suggested would increase the detection rate of chronic prostatic inflammation and potentially change the therapeutic approach in many patients with LUTS.

α1-Blockers in Men with Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Obstruction: Is Silodosin Different?

Available α1-blockers (ABs) have different profiles of receptor selectivity. Silodosin exhibits the highest selectivity for the α_1A adrenergic receptor. This pharmacological feature couples with a singular urodynamic and clinical profile. The magnitude of bladder outlet obstruction improvement in patients receiving silodosin is higher if compared to other ABs. From a clinical point of view, current evidence suggests an advantage in favor of silodosin in terms of nocturia improvement and cardiovascular safety. The incidence of ejaculatory dysfunction with silodosin is higher compared to other Abs.

Virtue male sling for post-prostatectomy stress incontinence: a prospective evaluation and mid-term outcomes

OBJECTIVE

To evaluate the efficacy and safety of the Virtue^® male sling (Coloplast, Humlebaek, Denmark) in a cohort of patients affected by post-prostatectomy stress urinary incontinence (SUI).

METHODS

All 29 consecutive patients treated with a Virtue male sling at our Institution between July 2012 and October 2013 were included in the present prospective, non-randomized study. Patients were evaluated preoperatively and at 1, 3, 6, 12, 24 and 36 months after surgery using a 24-h pad weight test, the International Consultation on Incontinence short-form questionnaire (ICIQ-SF), Urinary Symptom Profile (USP) questionnaire, a bladder diary, uroflowmetry and the Patient Global Impression of Improvement (PGI-I) and Patient Global Impression of Severity questionnaires.

RESULTS

The mean patient age was 65.5 years. A total of 72.4% of patients had preoperative mild incontinence (1-2 pads/day), while nine patients used 3-5 pads/day. There were a total of 17 complications, which occurred in 29 patients (58.6%); all were Clavien-Dindo grade I. At 12-month follow-up patients showed a significant improvement in 24-h pad test (128.6 vs 2.5 g), number of pads per day (2 vs 0), ICIQ-SF score (14.3 vs 0.9) and USP score for SUI (4 vs 0), and outcomes remained stable at 36 months. At last follow-up, the median score on the PGI-I questionnaire was 1 (very much better).

CONCLUSION

The Virtue male sling is an effective treatment option for low to moderate post-prostatectomy incontinence.

Biparametric 3T Magnetic Resonance Imaging for prostatic cancer detection in a biopsy-naïve patient population: a further improvement of PI-RADS v2?

OBJECTIVES

To prospectively determine the diagnostic accuracy of a biparametric 3T magnetic resonance imaging protocol (BP-MRI) for prostatic cancer detection, compared to a multiparametric MRI protocol (MP-MRI), in a biopsy naïve patient population.

METHODS

Eighty-two untreated patients (mean age 65±7.6years) with clinical suspicion of prostate cancer and/or altered prostate-specific antigen (PSA) levels underwent a MP-MRI, including T2-weighted imaging, diffusion-weighted imaging (with the correspondent apparent diffusion coefficient maps) and dynamic contrast enhanced sequence, followed by prostate biopsy. Two radiologists reviewed both the BP-MRI and the MP-MRI protocols to establish a radiological diagnosis. Receiver operating characteristics curves were obtained to determine the diagnostic performance of the two protocols.

RESULTS

The mean PSA level was 8.8±8.1ng/ml. A total of 34 prostatic tumors were identified, with a Gleason score that ranged from 3+3 to 5+4. Of these 34 tumors, 29 were located within the peripheral zone and 5 in the transitional zone. BP-MRI and MP-MRI showed a similar performance in terms of overall diagnostic accuracy, with an area under the curve of 0.91 and 0.93, respectively (p=n.s.).

CONCLUSIONS

BP-MRI prostate protocol is feasible for prostatic cancer detection compared to a standard MP-MRI protocol, requiring a shorter acquisition and interpretation time, with comparable diagnostic accuracy to the conventional protocol, without the administration of gadolinium-based contrast agent.
