RESUMO

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

RESUMO

INTRODUCTION: Urological cancers can be challenging in the diagnosis and treatment of patients with neurological diseases. As a result, there are still uncertainties regarding the incidence and risk factors favouring the development of urological cancers in these patients. The aim of this study was to review the available evidence regarding the incidence for the development of urological cancers in neurological patients to provide a basis for future recommendations and research. EVIDENCE ACQUISITION: A narrative review of the literature in Medline and Scopus up to June 2019 was performed. EVIDENCE SYNTHESIS: After screening 1729 records, 30 retrospective studies were retained. For bladder cancer (BC), 21 articles were identified, including a total of 673,663 patients. Among these patients, 4744 had a diagnosis of BC (1265 females, 3214 males, gender not reported in 265). In this group, 2514 were diagnosed with BC associated with a neurological disease. For prostate cancer (PC), 14 articles were identified, including a total of 831,889 men. Among these patients, 67,543 had a diagnosis of PC and 1457 had PC and a neurological disease. Two articles reported kidney cancer (KC), one reported testicular cancer (TC) and none described penile cancer or urothelial carcinomas of the upper urinary tract in neurological patients. CONCLUSIONS: The incidence of urological cancers, especially BC and PC, in patients with neurological diseases appears comparable to the general population. However due to the paucity of studies, specific recommendations for the management are lacking in neurologically disabled patients. In this report we investigated the frequency of urinary tract cancers in patients with neurological diseases. We conclude that urological cancers, especially bladder and prostate cancer, in patients with neurological diseases occur with similar frequency as in the general population.

RESUMO

BACKGROUND: Urinary diversions after radical cystectomy (RC) have a significant impact on quality of life and body image. Particularly for orthotopic neobladder (ONB), the rate of continence, urinary retention and urinary tract infections can impact on patient's quality of life. The aim of this study was to investigate whether early clean intermittent catheterization (CIC) might improve functional outcomes, continence status, and reduce the incidence of UTIs in patients with ONB. METHODS: In this prospective randomized study patients were divided in two groups. Patients were on a standard postoperative care (group A) or started CIC within the first postoperative month (group B). All patients were evaluated postoperatively at 1, 3, 6, and 9 months after ONB. The CIC was executed 4 times/daily after each voluntary micturition. The postoperative evaluation included: post-void residual volume (PVR), urine analysis and culture, number of pads/day and the self-administrated questionnaire International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). RESULTS: Thirty-nine male and 8 female patients underwent laparoscopic or robotic RC with intracorporeal ONB (37 U shaped and 10 Padua reconstructions). At the first follow up, mean PVR was in group A and B, 136.5 mL and 125.7 mL (P value: 0.105), respectively. The ICIQ-UI SF mean score was 16.2 and 17.1 (P value: 0.243) respectively and the mean no. of pads/day was 3 in both groups. 15 patients in group A and 10 in group B reported episodes of symptomatic UTIs. At 3, 6 and 9 months follow up after surgery the PVR and the ICIQ-UI SF scores were significantly improved (P value <0.0001). The number of pads decreased to 2 pads/day in group A and 1 in group B at 9 months. The episodes of UTIs significantly decreased over the time (P value <0.0001). CONCLUSIONS: Our data support the early introduction of self CIC in patients with ONB after RC. The CIC was significantly associated a reduced risk of incontinence, urinary retention, and UTI with significant improvement in QoL. These encouraging data need to be confirmed by further investigations with a larger number of patients.

RESUMO

Benign prostatic hypertrophy (BPH) is a condition that appears with advancing age and affects 1/3 of men over 50 years, resulting in filling and emptying symptoms. One of the main limitations of endoscopic techniques for BPH is the occurrence of retrograde ejaculation. The purpose of this prospective observational study is to evaluate the efficacy and feasibility of ejaculation-sparing thulium laser enucleation of the prostate (ES-ThuLEP) in the treatment of BPH-related LUTS and the preservation of ejaculation. Sexually active patients with BPH were enrolled and followed up with at 3, 6, and 12 months after surgery. Personal and pharmacological histories were collected, while three standardized questionnaires­the International Index of Erectile Function short form (IIEF-5), the International Consultation on Incontinence Questionnaire for Male Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ­MLUTSsex), and the International Prostatic Symptom Score (IPSS)­were administered. In addition, all patients underwent uroflowmetry and an assessment of post-void residual volume (PVR). A total of 53 patients were enrolled. A statistically significant improvement in the IPSS score, maximum flow (Qmax), and post-void volume (PVR) at 3 months, 6 months, and 12 months after surgery was found (p < 0.05), while no statistically significant differences were reported between IIEF-5 scores before and after surgery. A total of 48 patients (88.6%) had preserved ejaculation at 3 months, while 92.4% and 94.3% of patients reported preserved ejaculation at 6 and 12 months, respectively. Nevertheless, some degree of hypoposia was referred, at 3, 6, and 12 months, by 43.7%, 30.6%, and 13.2% of patients, respectively. The ES-ThuLEP technique successfully preserved ejaculation in over 90% of patients, representing an ejaculation-sparing alternative in the treatment of BPH.

RESUMO

Catheter-associated infections in bladder cancer patients, following radical cystectomy or ureterocutaneostomy, are very frequent, and the development of antibiotic resistance poses great challenges for treating biofilm-based infections. Here, we characterized bacterial communities from catheters of patients who had undergone radical cystectomy for muscle-invasive bladder cancer. We evaluated the efficacy of conventional antibiotics, alone or combined with the human ApoB-derived antimicrobial peptide r(P)ApoBLAla, to treat ureteral catheter-colonizing bacterial communities on clinically isolated bacteria. Microbial communities adhering to indwelling catheters were collected during the patients' regular catheter change schedules (28 days) and extracted within 48 h. Living bacteria were characterized using selective media and biochemical assays. Biofilm growth and novel antimicrobial strategies were analyzed using confocal laser scanning microscopy. Statistical analyses confirmed the relevance of the biofilm reduction induced by conventional antibiotics (fosfomycin, ceftriaxone, ciprofloxacin, gentamicin, and tetracycline) and a well-characterized human antimicrobial peptide r(P)ApoBLAla (1:20 ratio, respectively). Catheters showed polymicrobial communities, with Enterobactericiae and Proteus isolates predominating. In all samples, we recorded a meaningful reduction in biofilms, in both biomass and thickness, upon treatment with the antimicrobial peptide r(P)ApoBLAla in combination with low concentrations of conventional antibiotics. The results suggest that combinations of conventional antibiotics and human antimicrobial peptides might synergistically counteract biofilm growth on ureteral catheters, suggesting novel avenues for preventing catheter-associated infections in patients who have undergone radical cystectomy and ureterocutaneostomy.

RESUMO

Introduction: Aims of this study were to evaluate the functional outcomes of a vaginal wall sling technique in patients with stress urinary incontinence at 20 years after surgery and to evaluate the patient's satisfaction after the surgical procedure. Material and Methods: This was a prospective single-center study on patients with stress urinary incontinence who underwent in situ vaginal sling surgery. Presurgery evaluation included history, pelvic examination, and urodynamic test. All patients completed Urogenital Distress Inventory-6 (UDI-6) questionnaire. They underwent checkups at 1, 3, 6, and 12 months postoperatively and then annually. The sling was created by making a rectangle (15-20 × 25 mm) on the anterior vaginal wall and it was reinforced by one roll of Marlex mesh on each side of the sling. The sutures were passed through the vagina at the suprapubic level after suprapubic incision, above the rectus fascia and tied without excessive tension. Results: From May 1996 to May 2002, 40 women underwent vaginal wall sling surgery for stress urinary incontinence. Last visit was performed on 20 women between March 2020 and April 2020. Median follow-up was 251.3 months (20.9 years) (range = 204.3-285.4 months). The success rate after 5 years of surgical procedure was 80%; over 5 years, the objective cure rate was 45%. Considering only the group of 13 patients with pure stress urinary incontinence, the objective cure rate decreased to 38%, in particular 7 years after surgery. Women who did not resolve their urinary incontinence needed to undergo a new treatment. At over 5 years after surgery, there was an increase in urgency (p = 0.001) and voiding symptoms (p = 0.008) and urgency urinary incontinence (UUI) (p = 0.04). Ninety-five percent were very much worse or much worse according to the Patient Global Impression of Improvement (PGI-I) scale. Conclusion: The in situ vaginal wall sling does not guarantee good long-term functional outcomes in women with stress urinary incontinence.

RESUMO

OBJECTIVES: Aim of this study was to evaluate urodynamic effects and functional outcomes after anterior colporrhaphy and bilateral sacrospinous hysteropexy (SSH) in patients with stages II-IV pelvic organ prolapse (POP). STUDY DESIGN: This is a single-centre prospective study. Sixty-two women affected by anterior/central compartment prolapse of stage II-IV u ndergoing anterior colporrhaphy and bilateral SSH were recruited from our pelvic center. The preoperative evaluation included history, clinical examination, uroflowmetry and urodynamic studies (UDS). Six months after surgery, all patients performed UDS, completed the Urogenital Distress Inventory (UDI)-6, the Incontinence Impact Questionnaire (IIQ-7) and the Patient Global Impression of Improvement (PGI-I) questionnaire. RESULTS: Median follow-up study was 11 months (range 6-24). Q max significantly improved compared with baseline (21.1 ± 7.3 vs 12.3 ± 7.1 ml/s; p = 0.005) and the percentage of patients with PVR > 30% of premicturitional bladder volume significantly decreased (33.3% vs 11.1%; p = 0.001). At baseline, 24 (38.7%) women had typical phasic DO. Six months after surgery, DO was detected in only eleven women (17.7%) (p < 0.0001), with no de novo cases. Thirteen (21%) women reported SUI preoperatively which persisted in 5 patients (8.1%) after surgery, with no de novo cases. BOO was observed in only eight (12.9%) patients postoperatively compared with 51 (82.3%) at baseline (p < 0.0001). At last follow up visit, the UDI-6 and IIQ-7 total median scores improved significantly (p < 0.001). CONCLUSIONS: Combination of anterior colporrhaphy and bilateral SSH in women with advanced POP provides good functional outcomes, as demonstrated by the urodynamic findings before and after surgery.

RESUMO

PURPOSE: Stress urinary incontinence (SUI) related to pelvic organ prolapse represents a common condition that negatively impacts female sexual activity. Laparoscopic pelvic organ prolapse surgery (POPs) and the anterior repair with a trocar-less trans-vaginal mesh (TTMs) represent two different surgical techniques to treat SUI secondary to POP. This study aimed to report the results of these techniques comparing the sexual and functional outcome improvement. MATERIALS AND METHODS: Fifty-nine sexually active female patients, complaining of urodynamic stress incontinence, were enrolled in this prospective study, and simply randomized in two groups: 29 POPs and 30 TTMs. All patients were studied at baseline and 6 months after surgery. Preoperative evaluation included medical history, urodynamic test, Female Sexual Function Index (FSFI), and pelvic magnetic resonance defecography. Six months after surgery, all patients completed the FSFI and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and were investigated with a uroflowmetry test with post-void residual volume (PVR). RESULTS: At 6 months after surgery, 87% of POPs patients and 79% of TTMs subjects resulted dry. No statistically significant results were obtained in terms of urinary outcomes between the two surgical groups. Regarding sexual function, POPs group exhibited a significant greater improvement of global FSFI (mean: 27.4; SD: 4.31) compared to TTMs group (mean FSFI: 23.56; SD: 2.28; p-value ≤ 0.0001). CONCLUSIONS: Our results indicated that POPs and TTMs lead to satisfactory and safe functional outcomes with a good recovery of urinary continence. Furthermore, POPs, when compared to TTMs, led to a greater improvement of sexual function.

RESUMO

INTRODUCTION: Complications due to prosthetic surgery with mesh implantation may be misunderstood due to the insidious clinical presentation and inexperience of many surgeons if not adequately trained for the purpose. CASE REPORT: A 45-year-old female underwent a trans obturator tape procedure to correct severe stress urinary incontinence 3 months after surgery she developed urethral pain. The sling was partially removed, but the pain persisted. No residue sling was visualized by cystoscopies after surgery, and the pain was attributed to a psychiatric problem. She was treated with opioids, pregabalin without improvement of pain, until an extrusion of the sling into the urethra has been diagnosed by a careful urethrocystoscopy. CONCLUSION: It has been treated in our department by the removal of the residual sling, plus urethroplasty. The patient was followed up at 6 months with resolution of the painful symptoms.

RESUMO

INTRODUCTION AND HYPOTHESIS: The aims of this study were to evaluate by transperineal ultrasound if there were ultrasound-detectable changes over time in the dynamic behavior of the sling in patients who underwent transobturator tape (TOT), and to evaluate if dynamic translabial ultrasonography recognized factors that may be associated with failed surgery. METHODS: This was a single-center prospective study. We included women who underwent "out-in" TOT for stress urinary incontinence (SUI). A dynamic translabial ultrasound was performed 6 months post-surgery and again at the last visit. The objective cure for SUI was defined as the absence of urine leakage during the stress test. We evaluated the bladder neck mobility at rest and during Valsalva; the position of the mesh along the urethra; the concordance of urethral movement with the sling during Valsalva; the symmetry of the lateral arms of the sling during straining; and the presence or absence of bladder neck funneling. RESULTS: From December 2012 to February 2016, 80 consecutive patients were included. Six months after surgery, incontinent women compared with continent women had the sling in a proximal or distal position, that moved discordantly with the urethra (p < 0.0001), with asymmetry arm and bladder neck funneling (p < 0.0001). Continent patients had a significant improvement of urethrocele grade both at rest (p = 0.036) and during Valsalva (p = 0.045). CONCLUSIONS: Technical and positioning errors can lead to the failure of anti-incontinence surgical treatment. Translabial ultrasound allows the correct positioning of the sling to be evaluated and any errors that need to be analyzed in order to then solve the failure.

RESUMO

BACKGROUND: The impact of warm ischemia time (WIT) on renal functional recovery remains controversial. We examined the length of WIT>30 min on the long-term renal function following on-clamp partial nephrectomy (PN). METHODS: Data from 23 centers for patients undergoing on-clamp PN between 2000 and 2018 were analyzed. We included patients with two kidneys, single tumor, cT1, minimum 1-year follow-up, and preoperative eGFR≥60 mL/min/1.73m2. Patients were divided into two groups according to WIT length: group I "WIT≤30 min" and group II "WIT>30 min." A propensity-score matched analysis (1:1 match) was performed to eliminate potential confounding factors between groups. We compared eGFR values, eGFR (%) preservation, eGFR decline, events of chronic kidney disease (CKD) upgrading, and CKD-free progression rates between both groups. Cox regression analysis evaluated WIT impact on upgrading of CKD stages. RESULTS: The primary cohort consisted of 3526 patients: group I (N.=2868) and group II (N.=658). After matching the final cohort consisted of 344 patients in each group. At last follow-up, there were no significant differences in median eGFR values at 1, 3, 5, and 10 years (P>0.05) between the matched groups. In addition, the median eGFR (%) preservation and absolute eGFR change were similar (89% in group I vs. 87% in group II, P=0.638) and (-10 in group I vs. -11 in group II, P=0.577), respectively. The 5 years new-onset CKD-free progression rates were comparable in the non-matched groups (79% in group I vs. 81% in group II, log-rank, P=0.763) and the matched groups (78.8% in group I vs. 76.3% in group II, log-rank, P=0.905). Univariable Cox regression analysis showed that WIT>30 min was not a predictor of overall CKD upgrading (HR:0.953, 95%CI 0.829-1.094, P=0.764) nor upgrading into CKD stage ≥III (HR:0.972, 95%CI 0.805-1.173, P=0.764). Retrospective design is a limitation of our study. CONCLUSIONS: Our analysis based on a large multicenter international cohort study suggests that WIT length during PN has no effect on the long-term renal function outcomes in patients having two kidneys and preoperative eGFR≥60 mL/min/1.73m2.

RESUMO

INTRODUCTION: Sacrocolpopexy (SC) is the main treatment option for the repair of anterior and apical pelvic organ prolapse (POP). Indications and technical aspects are not standardized, and the question remains whether it is necessary to place a mesh on both anterior and posterior vaginal walls, particularly in cases with only minor or no posterior compartment prolapse. The present study aimed to compare the anatomical and functional outcomes of single anterior mesh only versus anterior and posterior mesh procedures in SC. MATERIALS AND METHODS: Our prospectively maintained database on POP was used to identify patients who had undergone either abdominal or mini-invasive SC from January 2006 to October 2019. Patients with symptomatic or unmasked stress urinary incontinence (SUI) were not included in the study and were treated using the pubo-vaginal cystocele sling procedure. Objective outcomes included clinical evaluation of pre-existing or de novo POP by the halfway system and POP-q classifications, as well as the development of de novo SUI. Subjective outcomes were assessed using the Pelvic Floor Impact Questionnaire (PFIQ-7) with questions on bladder, bowel, and vaginal functions. Persistent or de novo constipation and overactive bladder were defined as bowel symptoms and urinary urgency/frequency/urinary incontinence after surgery. RESULTS: Ninety-five women with symptomatic anterior and apical POP underwent SC. Forty-one patients were treated with only anterior vaginal mesh (group A), and 54 with anterior and posterior mesh (group B). There were no differences between the pre- and post-operative characteristics of the 2 groups. In group B, there were 2 blood transfusions, 1 wound dehiscence, and 3 mesh erosions/extrusion after abdominal SC (Clavien-Dindo II), and in group A, there was 1 ileal lesion after laparoscopic SC (Clavien-Dindo III). There were no differences between the 2 groups in either anatomical or functional outcomes during 3 years of follow-up. CONCLUSIONS: SC with single anterior vaginal mesh has similar results to SC with combined anterior/posterior mesh, regardless of the surgical approach. The single anterior mesh may reduce the risk of complications (mesh erosion/extrusion), and offers better subjective outcomes with improved quality of life. Anterior/posterior mesh may be justified in the presence of clinically significant posterior POP.

RESUMO

Pooling radiomic features coming from different centers in a statistical framework is challenging due to the variability in scanner models, acquisition protocols, and reconstruction settings. To remove technical variability, commonly called batch effects, different statistical harmonization strategies have been widely used in genomics but less considered in radiomics. The aim of this work was to develop a framework of analysis to facilitate the harmonization of multicenter radiomic features extracted from prostate T2-weighted magnetic resonance imaging (MRI) and to improve the power of radiomics for prostate cancer (PCa) management in order to develop robust non-invasive biomarkers translating into clinical practice. To remove technical variability and correct for batch effects, we investigated four different statistical methods (ComBat, SVA, Arsynseq, and mixed effect). The proposed approaches were evaluated using a dataset of 210 prostate cancer (PCa) patients from two centers. The impacts of the different statistical approaches were evaluated by principal component analysis and classification methods (LogitBoost, random forest, K-nearest neighbors, and decision tree). The ComBat method outperformed all other methods by achieving 70% accuracy and 78% AUC with the random forest method to automatically classify patients affected by PCa. The proposed statistical framework enabled us to define and develop a standardized pipeline of analysis to harmonize multicenter T2W radiomic features, yielding great promise to support PCa clinical practice.

RESUMO

BACKGROUND: Bladder pain syndrome/interstitial cystitis (BPS/IC) or primary bladder pain syndrome (PBPS) is a complex and poorly understood condition. This comprehensive review aimed to discuss the potential application of platelet-rich plasma (PRP) in the treatment of BPS/IC. The pathophysiology of BPS/IC is characterized by urothelial damage that triggers a chain of events leading to chronic inflammation and other conditions. Frequently, in subjects affected by BPS/IC, recurrent urinary tract infection (rUTI) is associated with difficult therapeutic management. For these reasons, many oral and intravesical treatments (e.g., antibiotic therapy and intravesical anesthetic instillations) have been proposed to alleviate the symptoms of IC/BPS. However, the limitation of these treatments is the short duration of improvement. The purpose of this review is to analyze the efficacy of intravesical PRP injections in subjects with PBS/IC and to try to understand the potential therapeutic effects on the pathophysiology of this disease. METHODS: A nonsystematic literature search using Pubmed, EMBASE, Scopus, Web of Science, Medline was performed from January 2000 to August 2021. The following terms were combined to capture relevant publications: "platelet-rich plasma", "interstitial cystitis", "PRP", "bladder pain syndrome", and "painful bladder syndrome". RESULTS: After exclusion of non-pertinent studies/articles, we have analyzed 5 studies. In detail, 2 articles concerned preclinical studies in which animal models were used. The authors showed an improvement in the histological pattern with less bleeding in treated subjects, a lower presence of inflammatory cytokines and an increase in the mitotic index of urothelial cells in animals treated with intravesical PRP. In the three prospective clinical trials analyzed, patients with BPS/IC who underwent monthly intravesical PRP injections were found to have a statistically significant improvement in symptoms with modulation of growth factors and inflammatory proteins. CONCLUSIONS: New evidence suggests that treatment with intravesical PRP could improve urothelial regeneration and reduces chronic inflammation in BPS/IC, modifying the clinical history of its pathology.

RESUMO

INTRODUCTION: The aim of this study was to assess whether antibiotic prophylaxis or therapy is sufficient for laparoscopic or vaginal prolapse surgery with mesh. METHODS: This is a single-center prospective study. The study was divided into 3 groups. Protocol A: metronidazole (15 mg/kg) and piperacillin-tazobactam (2 g) 1 h before surgery and, for postoperative treatment, gentamycin (160 mg) 1 h before surgery in a single dose. Metronidazole and piperacillin-tazobactam were administered until hospital discharge. Protocol B: gentamycin and piperacillin-tazobactam in the same manner as group A. Protocol C: clindamycin (600 mg) and gentamicin (160 mg) 1 h before surgery in a single dose. RESULTS: We included 87 consecutive patients who underwent prolapse surgery involving mesh prostheses: 57 by the laparoscopic approach and 30 by the vaginal route. Of these, 30 patients were included in protocol A, 30 in protocol B, and 27 in protocol C. There were no statistically significant differences among the 3 protocols regarding any postoperative complications, except for urinary tract infections that were more in the vaginal approach than in the laparoscopic route, in protocol A (p = 0.002). CONCLUSIONS: One-shot prophylaxis can be successfully used in prolapse surgery regardless of the surgical approach.

RESUMO

Bilateral Primary testicular lymphoma (PTL) is a rare and aggressive non-Hodgkin extranodal lymphoma. Despite this low overall incidence, it is the most common testicular cancer in the elderly. PTL is characterized by spreading to non-contiguous extranodal sites (especially in SNC), high recurrence rate and poor prognosis. We report a case of a 55-year old man with advanced bilateral PTL without specific symptoms who underwent a combined multimodal approach.

RESUMO

BACKGROUND: Peyonie's disease (PD) mostly affects males in the fifth decade of life, with a prevalence in the general population ranging between 0.5% and 20.3%. The pathology of PD is characterized by fibrosis of the tunic albuginea of the cavernous bodies of the penis, with the presence of pain in the erection and penile deformity. This is associated with decreased sexual function for both participants. The objective of the study was to investigate the influence of PD pathology on both male patients' and their female partners' sexual spheres, and analyze changes in sexual function and perception following penile correction surgery. METHODS: Prospective study, we included male patients with PD and their female partner sexually active. Patients underwent corporoplasty with multiple plications. The male and female sexuality was evaluated before surgery and three months after male treatment by the Female sexual Function Index (FSFI); International Index of Erectile Function (IIEF); Visual Analogical Scale (VAS). RESULTS: From January 2018 to November 2019 we included 35 couple. The female subjects before partner's surgery presented dyspareunia, loss of sexual desire, inability to achieve orgasm, and sexual dissatisfaction. At three months after surgical treatment there was an improvement of sexual function in both male patients and female partners (desire P<0.0001, arousal P<0.0001, lubrification P<0.0001, orgasm P<0.0001, satisfaction P<0.0001, pain P<0.0001). As regarding male patients the pain decreased significantly (VAS score from 6 to 2.5), while there was no statistically significant improvement in erectile function (P=0.05). CONCLUSIONS: Our findings suggest that a viable approach to treatment of PD patients that involves their partners could lead to better functional and psychological results.

RESUMO

BACKGROUND: It is known that a multitude of factors may lead to male factor infertility, but still, in the majority of cases, the cause remains largely idiopathic, reflecting poor understanding of the basic process of spermatogenesis and the mechanisms involved. Resveratrol is a polyphenol compound that displays several cellular aspects mainly associated with SIRT1-pathway activation and promotion of mitochondrial enhancer activities. In several animal models, resveratrol has shown positive effects on mitochondria and membrane potential. This could explain effects on sperm concentration and motility. The aim of this study is to evaluate the effects on the semen parameters of GENANTE®, a multivitamin supplement containing 150 mg of resveratrol/day, in patients with idiopathic infertility. METHODS: This was a prospective single center clinical study. Twenty patients took a multivitamin supplement based on 150 mg of resveratrol (GENANTE®), in the form of an oral tablet every 12 h, and were followed up at 1, 3, and 6 months after treatment. Pre- and post-treatment evaluation included history, clinical examination, semen analysis, hormonal determinations, and scrotal and prostatic ultrasound. RESULTS: Our preliminary pilot study demonstrated that the multivitamin supplement based on resveratrol improves sperm motility (48.3% ± 13.8 vs. 59.0% ± 12.8, p = 0.0001) and concentration (22.6×106/mL ± 9.5 vs. 25.7×106/mL ± 8.1, p = 0.0001) after 3 and 6 months of treatment in men with idiopathic infertility. CONCLUSION: Our data suggest that targeting the metabolic and energetic pathways involved in spermatogenesis and mitochondrial activity could lead to potential effects and counteract subfertility/infertility in men through a mitochondria dynamics mechanism.

RESUMO

About 70% of bladder cancers (BCs) are diagnosed as non-muscle-invasive BCs (NMIBCs), while the remaining are muscle-invasive BCs (MIBCs). The European Association of Urology (EAU) guidelines stratify NMIBCs into low, intermediate, and high risk for treatment options. Low-risk NMIBCs undergo only the transurethral resection of the bladder (TURB), whereas for intermediate-risk and high-risk NMIBCs, the transurethral resection of the bladder (TURB) with or without Bacillus Calmette-Guérin (BCG) immune or chemotherapy is the standard treatment. A minority of NMIBCs show unfavorable prognosis. High-risk NMIBCs have a high rate of disease recurrence and/or progression to muscle-invasive tumor and BCG treatment failure. The heterogeneous nature of NMIBCs poses challenges for clinical decision-making. In 2020, the EAU made some changes to NMIBCs BCG failure definitions and treatment options, highlighting the need for reliable molecular markers for improving the predictive accuracy of currently available risk tables. Nowadays, next-generation sequencing (NGS) has revolutionized the study of cancer biology, providing diagnostic, prognostic, and therapy response biomarkers in support of precision medicine. Integration of NGS with other cutting-edge technologies might help to decipher also bladder tumor surrounding aspects such as immune system, stromal component, microbiome, and urobiome; altogether, this might impact the clinical outcomes of NMBICs especially in the BCG responsiveness. This review focuses on NMIBCs with unfavorable prognoses, providing molecular prognostic factors from tumor immune and stromal cells, and the perspective of urobiome and microbiome profiling on therapy response. We provide information on the cornerstone of immunotherapy and new promising bladder-preserving treatments and ongoing clinical trials for BCG-unresponsive NMIBCs.

RESUMO

INTRODUCTION AND HYPOTHESIS: The aim of this study was to compare the outcomes in women who underwent laparoscopic sacrocolpopexy (LSC) with or without hysterectomy for pelvic organ prolapse (POP). METHODS: This was a single-centre prospective study. We included women with symptomatic POP (III-IV stage) who underwent LSC with or without hysterectomy. The preoperative evaluation included a history, clinical examination and urodynamic test; all patients completed FSFI, UDI-6 and IIQ-7 questionnaires. They were followed up at 1, 3, 6 and 12 months after surgery and then annually thereafter with the same preoperative flow chart. At the last visit, they also completed the PGI-I questionnaire. RESULTS: Between 2012 and 2016, a total of 136 patients with POP were included (82 in the LSC with hysterectomy group and 54 in the hysteropexy group). At a median follow-up of 65.3 months (36-84 months), there were improvements in the anatomical and functional outcomes of both groups without differences between the two approaches. The apical success rate was 100% in all women, without recurrence in either group; the anterior and posterior success rates of hysterectomy were higher than those of uterine preservation. CONCLUSION: This study showed that there were no differences in the anatomical and functional outcomes between LSC with or without hysterectomy for POP.
