Antibiotic prophylaxis in invasive urodynamics, a Delphi consensus of the Italian Society of Urodynamics (SIUD).

INTRODUCTION: Although antibiotic prophylaxis (AB) demonstrated a statistically significant reduction in bacteriuria after invasive urodynamics (UDS), no significant decrease in the incidence of urinary tract infections (UTI) has been confirmed. No absolute recommendations on the use of AB in case of relevant potential risk of UTI have been reported, though some categories of patients at increased infective probability after UDS have been recognized. The aim of this study is to report the experts' consensus on the best practice for the use of AB before UDS in the main categories of patients at potential risk of developing UTI. MATERIALS AND METHODS: A systematic literature review was performed on AB before UDS in males and females. A panel of experts from the Italian Society of Urodynamics, Continence, Neuro-Urology, and Pelvic Floor (SIUD) assessed the review data and decided by a modified Delphi method on 16 statements proposed and discussed by the panel. The cut-off percentage for the consensus was a ≥70% of positive responses to the survey. The study was a Delphi consensus with experts' opinions, not a clinical trial involving directly patients. RESULTS: The panel group was composed of 57 experts in functional urology and UDS, mainly urologists, likewise gynaecologists, physiatrists, infectivologists, pediatric urologists, and nurses. A positive consensus was achieved on 9/16 (56.25%) of the statements, especially on the need for performing AB before UD in patients with neurogenic bladder and immunosuppression. Urine analysis and urine culture before UDS are mandatory, and in the event of their positivity, UDS should be postponed. A consensus was reached on avoiding AB in menopausal status, diabetes, age, gender, bladder outlet obstruction, high postvoid residual, chronic catheterization, previous urological surgery, lack of urological abnormalities, pelvic organ prolapse, and negative urine analysis. CONCLUSIONS: Antibiotic prophylaxis is not recommended for patients without notable risk factors and with a negative urine test due to the potential morbidities that may result from antibiotic administration. However, AB can be used for risk categories such as neurogenic bladder and immunosuppression. The evaluation of urine analysis and urine culture and postponing UDS in cases of positive tests were considered good practices, as well as performing AB in the neurogenic bladder and immunosuppression.

Translabial ultrasound: a non-invasive technique for assessing "technical errors" after TOT failure.

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.

Prediction of significant renal function decline after open, laparoscopic, and robotic partial nephrectomy: External validation of the Martini's nomogram on the RECORD2 project cohort.

OBJECTIVES: Martini et al. developed a nomogram to predict significant (>25%) renal function loss after robot-assisted partial nephrectomy and identified four risk categories. We aimed to externally validate Martini's nomogram on a large, national, multi-institutional data set including open, laparoscopic, and robot-assisted partial nephrectomy. METHODS: Data of 2584 patients treated with partial nephrectomy for renal masses at 26 urological Italian centers (RECORD2 project) were collected. Renal function was assessed at baseline, on third postoperative day, and then at 6, 12, 24, and 48 months postoperatively. Multivariable models accounting for variables included in the Martini's nomogram were applied to each approach predicting renal function loss at all the specific timeframes. RESULTS: Multivariable models showed high area under the curve for robot-assisted partial nephrectomy at 6- and 12-month (87.3% and 83.6%) and for laparoscopic partial nephrectomy (83.2% and 75.4%), whereas area under the curves were lower in open partial nephrectomy (78.4% and 75.2%). The predictive ability of the model decreased in all the surgical approaches at 48 months from surgery. Each Martini risk group showed an increasing percentage of patients developing a significant renal function reduction in the open, laparoscopic and robot-assisted partial nephrectomy group, as well as an increased probability to develop a significant estimated glomerular filtration rate reduction in the considered time cutoffs, although the predictive ability of the classes was <70% at 48 months of follow-up. CONCLUSIONS: Martini's nomogram is a valid tool for predicting the decline in renal function at 6 and 12 months after robot-assisted partial nephrectomy and laparoscopic partial nephrectomy, whereas it showed a lower performance at longer follow-up and in patients treated with open approach at all these time cutoffs.

Extensive impact of COVID-19 pandemic on pelvic floor dysfunctions care: A nationwide interdisciplinary survey.

AIMS: To investigate the impact of COVID-19 pandemic on health-care provision to patients suffering from pelvic floor dysfunctions in Italy. METHODS: A retrospective web-based interdisciplinary survey was mailed by the Italian Society of Urodynamics to members involved in pelvic floor dysfunctions management from June 22, 2020 to July 17, 2020. The 84-item questionnaire investigated the period March-June 2020 (first epidemic wave) and showed high content validity. The primary outcome was the mean rate of cancellation for health-care services. Secondary outcomes included estimation of the accumulated surgeries backload until return to baseline activity and of the recovery pattern, using linear regression and scenario-based forecasting. RESULTS: A total of 85 participants provided complete responses. Respondents were mostly urologists (47%), followed by gynecologists (29.5%) and physiatrists (17.6%). On average, 78.4% of outpatient services and 82.7% of functional surgeries were canceled, without significant differences by geographical distribution. An impact on patients' quality of life was anticipated by most of the respondents (87%) and 48.2% also reported potentially serious health risks for patients. Thirty-three percent of the respondents reported the use of telemedicine. If the nation-wide surgical activity increases by 20% postpandemic, it would take 37 months to clear the backlog of functional surgeries. We acknowledge the inherent limitations of the survey methodology and retrospective design. CONCLUSIONS: Access to care for patients suffering from pelvic floor dysfunctions has been dramatically affected by the COVID-19 outbreak. The indirect effects of this unprecedented disruption on pelvic floor dysfunctions care may last for several months.

Phamacological treatment of persistant lower urinary tract symptoms after a transurethral resection of the prostate is predictive of a new surgical treatment: 10 years follow-up study.

AIM: To evaluate possible risk factors of re intervention in patients with benign prostatic enlargement (BPE) undergoing transurethral resection of the prostate (TURP). MATERIALS AND METHODS: A consecutive series of patients with LUTS and BPE underwent TURP in our center in 2004 and 2005 and they were then followed up to September 2016. Patients were assessed at baseline, 3-, 6-month postoperatively and yearly thereafter with medical history, international prostate symptom score, prostate specific antigen, maximal urinary flow rate, post void residual urine. Reoperation was defined as the requirement of a new TURP to relieve bothersome LUTS. Cox regression was used to determine covariates associated with reoperation rate and the Kaplan-Meier curve assessed the time to reoperation. RESULTS: Overall, 92 patients were enrolled. Median follow up was 142 months. 13 patients underwent a second TURP during the follow-up period (reoperation rate was 14%); out of them 9/13 (69%) received medical treatment for persistent LUTS (p = .001). The need of LUTS/BPE pharmacological treatment after TURP is an independent risk factor for a second surgical procedure (odds ratio 9,3; p = .001). Out of the 13 patients treated with a re-TURP, 12 (92%) underwent surgery within 5 years of follow-up. CONCLUSION: In our single center study, the need of LUTS/BPE pharmacological treatment was a predictive factor of a re-TURP. Considering that more than 90% of re-TURP were performed during the first 5 years of follow-up, it is assumable that a follow-up longer than 5 years is not needed in these patients.

Prevalence of nocturia after brain injury: a cross-sectional study in a single rehabilitation center.

Aim: to analyze the prevalence of nocturia and its possible neuro-urological correlations in patients with a history of acquired brain injury (ABI).Methods: a single-centre population-based prospective study involving outpatients who were previously admitted to our Rehabilitation Hospital for acute ABI ≥ 18 months and ≤2 years prior. Impact of nocturia on QoL was evaluated by the standardized International Consultation on Incotinence Nocturia Quality of Life (ICIQ N-QoL). All participants were given a three-day frequency chart. Probability value <0.05 was statistically significant.Results: 48/138 subjects (35%) showed nocturia at 2-year follow-up visit. No, significant differences in age, gender, duration of coma, state of consciousness, disability, cognitive impairment and stroke severity were found in patients with or without nocturia. Subarachnoid haemorrhage (ESA) was the main reason for ABI in subjects showing nocturia (p = .037). The overall ICIQ N-QOL score ranged from 12 to 50 (mean 30.12 ± 8.87). Of them, 75% showed a total score >26. Increased diurnal frequency and small bladder capacity was statistically significantly associated with nocturia (p < .05).Conclusions: the rate of nocturia 2 years following ABI was lower compared to other neurological populations, although it was significantly associated with other storage urinary symptoms.

Delayed graft function and perfusion parameters of kidneys from uncontrolled donors after circulatory death.

Better preservation and evaluation of kidneys from donors after circulatory death serve to increase the number of kidneys available for transplantation and hypothermic machine perfusion has been shown to decrease ischemia reperfusion injury and delayed graft function. Data on relation between hemodynamic parameters during hypothermic machine perfusion and delayed graft function in kidneys from donors after circulatory death are so far scarce and not univocal. We aimed at assessing whether hemodynamic parameters measured during hypothermic machine perfusion (flow, mean perfusion pressure, and renal resistance) are associated with delayed graft function in 26 kidneys retrieved from uncontrolled donors after circulatory death. In our series, the incidence of delayed graft function was 57.7% (15/26). Recipients who developed delayed graft function had a longer warm ischemic time (p = 0.04). All hemodynamic parameters measured during hypothermic machine perfusion were comparable between recipients with delayed graft function and those without. According to our data, in kidneys from uncontrolled donors after circulatory death, a longer warm ischemic time (that is the overall time of no flow, as the sum of the no-flow and the no-touch period) is associated with delayed graft function. This finding underscores the pivotal role of ischemic injury in terms of absence of flow in affecting graft function. No association was detectable between hemodynamic parameters during hypothermic machine perfusion and the development of delayed graft function in our series.

Advance Xp® Male Sling can be an Effective and Safe Treatment for Post-Prostatectomy Stress Urinary Incontinence Also in Patients with Prior History of External Beam Radiation Therapy: A Multicentric Experience.

Background. Post-prostatectomy stress urinary incontinence (PPSUI) is one of the major complaints after radical prostatectomy. Transoburator male sling (TMS) placement is indicated in persistent mild to moderate PPSUI. External beam radiation therapy (EBRT) might be a negative prognostic factor for TMS outcomes. Study objective was to analyze EBRT impact on TMS outcome. Methods. We retrospectively investigated patients submitted to TMS for PPSUI, with or without previous EBRT, in two tertiary referral centers since 2010. Objective outcome was measured through ICIQ-SF, 1-hour pad test, and pad per die and subjective improvement through PGI-I. Patients were divided according to EBRT to make in-group and between-group comparisons. Results. Patients were 56, 18 (32.1%) had previous EBRT. Median follow-up was 43.0 months (IQR: 22.3-64.0). TMS was placed at mean 18.8 months (SD 4.6) after EBRT. TMS determined a statistically significant reduction of pads, 1-hour pad test, and ICIQ-SF score (P<.05). Improvement diminished during long-term follow-up. At last follow-up, 12 patients (21.4%) used 1 safety pad, while 15 (26.8%) used 0 pads. Median PGI-I was 2 (IQR 2-3). Recorded complications were 9 (16.1%) and none exceeded Clavien-Dindo grade 2. There were no differences in outcomes, failures, and complications between groups. TMS failures were 6 (10.7%), 2 of whom in the EBRT group. Four of them (7.1%) subsequently placed an artificial urinary sphincter (AUS). Conclusion. Advance XP© placement seems effective and safe in well-selected patients complaining with PPSUI, even after EBRT. Surgical outcomes slightly deteriorate over time. Further studies are needed in these patients to assess TMS efficacy.

Angiosarcoma of the Urinary Bladder Following Radiotherapy: Report of a Case and Review of the Literature.

Background and objectives: Angiosarcomas are uncommon and extremely aggressive malignancies derived from vascular endothelial cells. Although they can occur anywhere in the body and at any age, they are more frequently found in the skin of the head and neck regions and in the elderly. Few cases have been recorded in deep soft tissues and in parenchymal organs. Angiosarcomas of the urinary bladder are exceedingly rare. They usually arise in adult patients with a history of radiation therapy, cigarette smoking, or exposure to chemical agents (e.g., vinyl chloride). Despite multidisciplinary treatment approaches combining surgery, radiotherapy, and chemotherapy, prognosis is dismal. Materials and Methods: We describe a case of a 78-year-old Caucasian man presenting with a vesical mass incidentally discovered with abdominal computerized tomography (CT). He underwent transurethral resection of the bladder (TURB), and histology was compatible with angiosarcoma. Results: The patient had been a heavy smoker and his medical history included therapeutic irradiation for prostate cancer eight years previously. Radical cystoprostatectomy was feasible, and pathologic examination of the surgical specimen confirmed angiosarcoma involving the urinary bladder, prostate, and seminal vesicles. Post-operative peritonitis resulted in progressive multi-organ failure and death. Conclusions: Angiosarcoma primary to the urinary bladder is seldom encountered, however, it should be considered in the differential diagnosis of vesical tumors, especially in elderly men with a history of pelvic radiotherapy.

Utilization rate of uncontrolled donors after circulatory death-a 3-year single-center investigation.

BACKGROUND: Effectiveness of uncontrolled donation after circulatory death (uDCD) has been recently reported to be 75% according to data coming from some European countries in 2016, but few data are to date available on this topic. METHODS: We assessed the utilization rate (as the percentage of donors who were converted into actual donors) in 37 uDCDs consecutively enrolled at our Center (Careggi Teaching Hospital) from June 2016 to June 2019. RESULTS: In three cases, the family did not give consent for donation (3/37, 8.1%). Among the 37 potential uDCDs, 22 became actual donors (22/37, 59%), with 10 livers and 38 kidneys being transplanted, respectively. Fifteen livers were recovered (15/37, 68%), and 10 livers were transplanted (10/15, 67%). Forty-two kidneys were procured and 38 organs transplanted. The overall effectiveness was 78%. CONCLUSIONS: According to our 3-year experience, uncontrolled DCDs do represent an additional means of increasing the number of transplanted organs (kidneys and livers) with an acceptable utilization rate. Research on organ viability assessment (for both livers and kidneys from uDCDs) is still in its infancy, and there is probably space for a further wider use of organs from uDCDs.

Development of a robot-assisted kidney transplantation programme from deceased donors in a referral academic centre: technical nuances and preliminary results.

OBJECTIVE: To report the development of the first robot-assisted kidney transplantation (RAKT) programme from deceased donors, examining technical feasibility and early perioperative and functional outcomes at a referral academic centre. PATIENTS AND METHODS: A RAKT programme was developed in 2016 at our institution following structured modular training. Specific inclusion/exclusion criteria for both living and deceased donors were set. Data from patients undergoing RAKT from January 2017 to April 2018 were prospectively collected in an a priori developed web-based data set. RAKT followed the principles of the Vattikuti Urology Institute-Medanta technique, with specific technical modifications based on clinical recipient characteristics, as well as surgeon's skills and preference during the learning curve. Technical feasibility of RAKT from deceased donors and evaluation of perioperative and early functional outcomes were the main study endpoints. RESULTS: In all, 17 RAKTs were performed during the study period. Of these, six were from living donors and 11 were from deceased donors. All RAKTs were successfully completed without need of conversion. The median (interquartile range [IQR]) console time was 190 (160-220) min and the median (IQR) estimated blood loss was 120 (110-140) mL. The median times to complete venous, arterial and uretero-vesical anastomoses were 21, 22 and 21 min, respectively. The median (IQR) length of stay was 8 (6-12) days. At a median (IQR) follow-up of 8 (6-11) months, five (30%) complications were recorded. Of these, four (24%) were minor (Clavien-Dindo Grade I-II) and one major (Clavien-Dindo Grade IIIb, requiring graft nephrectomy). Overall, two patients were still on dialysis at last follow-up. A significant improvement in graft function was recorded progressively at all postoperative time points. CONCLUSION: Our preliminary experience outlines that: (i) the development of a RAKT programme is feasible in centres experienced in robotic surgery and open kidney transplantation; (ii) RAKT from deceased donors is feasible from both a technical and logistical perspective; and (iii) RAKT from deceased donors appears to achieve favourable early postoperative and functional outcomes. Larger studies with longer follow-up are needed to confirm these findings and compare the outcomes of RAKT from deceased donors with those from living donors.

Nomogram for predicting the likelihood of postoperative surgical complications in patients treated with partial nephrectomy: a prospective multicentre observational study (the RECORd 2 project).

OBJECTIVE: To identify meaningful predictors and to develop a nomogram of postoperative surgical complications in patients treated with partial nephrectomy (PN). PATIENTS AND METHODS: We prospectively evaluated 4308 consecutive patients who had surgical treatment for renal tumours, between 2013 and 2016, at 26 Italian urological centres (RECORd 2 project). A multivariable logistic regression for surgical complications was performed. A nomogram was created from the multivariable model. Internal validation processes were performed using bootstrapping with 1000 repetitions. RESULTS: Overall, 2584 patients who underwent PN were evaluated for the final analyses. The median (interquartile [IQR]) American Society of Anesthesiologists (ASA) score was 2 (2-3). In all, 72.4% of patients had clinical T1a (cT1a) stage tumours. The median (IQR) Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 7 (6-8). Overall, 34.3%, 27.7%, 38% of patients underwent open PN (OPN), laparoscopic PN (LPN), and robot-assisted PN (RAPN). Overall and major postoperative surgical complications were recorded in 10.2% and 2.5% of patients, respectively. At multivariable analysis, age, ASA score, cT2 vs cT1a stage, PADUA score, preoperative anaemia, OPN and LPN vs RAPN, were significant predictive factors of postoperative surgical complications. We used these variables to construct a nomogram for predicting the risk of postoperative surgical complications. At decision curve analysis, the nomogram led to superior outcomes for any decision associated with a threshold probability of >5%. CONCLUSION: Several clinical predictors have been associated with postoperative surgical complications after PN. We used this information to develop and internally validate a nomogram to predict such risk.

No Treatment Required for Asymptomatic Vaginal Mesh Exposure.

INTRODUCTION: There is no specific recommendation for the management of asymptomatic vaginal mesh erosions post antiincontinence or prolapse surgery, but revision or excision may represent overtreatment. We hypothesize that asymptomatic vaginal exposures remain asymptomatic during follow-up and do not require any intervention. METHODS: We evaluated a "no treatment" approach by prospectively following-up women with asymptomatic vaginal exposures after antiincontinence and pelvic organ prolapse surgery. After a 1-month course of vaginal oestrogen, they underwent the "wait and see" protocol. It consisted of no treatment. Women were followed-up every 3 months, for the first year and then every 6 months with history, clinical examination with measurement of size of the exposure, and the evaluation of possible infection signs or vaginal discharge. RESULTS: Forty women were followed-up for a median of 33.52 months (range 8-48 months). All exposures were ≤1 cm (mean 6.5 ± 1.5 mm, range 4-10 mm), patients were asymptomatic and without pain. During the observation period, the size of the exposure did not change and all women remained asymptomatic. DISCUSSION/CONCLUSION: No treatment seems to be required for asymptomatic and small vaginal mesh exposures after prolapse or incontinence surgery.

Full Robot-Assisted Living Donor Nephrectomy and Kidney Transplantation in a Twin Dedicated Operating Room: Initial Experience From a High-Volume Robotic Center.

Purpose. To describe our initial experience with a full robot-assisted approach for living donor nephrectomy (RALDN) and kidney transplantation (RAKT) in a dedicated twin operating room. Methods. From January to December 2017, 5 cases of RALDN and RAKT were performed in a single high-volume robotic center. All patients underwent a standard left RALDN. The renal hilum was controlled with Hem-O-Lok clips (WECK) and the kidney extracted through a Pfannenstiel incision. RAKT was performed according to the Vattikuti Urology Institute-Medanta technique. Results. RALDN: median estimated blood loss was 182 mL (range = 80-450 mL), no postoperative blood transfusion was required. The median (range) warm ischemia time was 175 (90-220 seconds). No conversion was registered. Median console time was 143 minutes (range = 115-220 minutes). No major surgical intraoperative and postoperative early and late complications occurred. RAKT: all 5 patients successfully underwent RAKT. Median (range) console time was 230 (190-200) minutes, vascular suture time was 58.7 (48-73) minutes, cold ischemia time was 46.2 (30-88) minutes, and rewarming time was 61.2 (55-72) minutes. No conversion was required. No major surgical intraoperative and postoperative early and late complications occurred. Mean glomerular filtration rate at days 1, 3, and 7 postoperatively was 26, 42, and 57 (range = 6-90) mL/min/1.73 m2, respectively. No case of delayed graft function was observed. No anastomosis revision, urological complications, lymphocele, and surgical site infection occurred. Conclusions. In our experience, RALDN and RAKT are safe and effective. The intuitiveness of the robotic approach provided substantial benefits both for the living donor and recipient from the very beginning of our series. No intraoperative and postoperative complications occurred.

A metabolic approach during normothermic regional perfusion in uncontrolled donors after circulatory death-A pilot study.

The use of donation after circulatory death (DCD) has increased significantly to face the persistent mismatch between supply and demand of organs for transplantation. While controlled (c) DCDs have warm ischemic time (WIT) that can be estimated, the WIT is often inexact and extended in uncontrolled DCD (uDCD), making assessment of injury difficult. We aimed at investigating the effects of cold ischemia on potential donor organ damage in the course of nRP by assessing the dynamic variations of transaminases and creatinine values in 17 uDCD donors. In our series, lactate values did not show significant changes during the study period (P = 0.147). Creatinine values did not significantly changed while transaminases progressive increased throughout the study period, even if it was significant only for AST (P = 0.035). According to our data, nRP duration affects splanchnic organs, being the liver sensitive to hypoperfusion, and serial biochemical measurements could help in detecting organ functional status.

Alpha-1 adrenergic antagonists, 5-alpha reductase inhibitors, phosphodiesterase type 5 inhibitors, and phytotherapic compounds in men with lower urinary tract symptoms suggestive of benign prostatic obstruction: A systematic review and meta-analysis of urodynamic studies.

AIMS: To perform a systematic review and meta-analysis of studies evaluating the urodynamic outcomes of alpha-1 adrenergic antagonists (ABs), 5-alpha reductase inhibitors (5-ARIs), phosphodiesterase type 5 inhibitors (PDE5is), and phytotherapic compounds in patients with lower urinary tract symptoms related to benign prostatic obstruction (LUTS/BPO). METHODS: A systematic review of PubMed/Medline, ISI Web of Knowledge, and Scopus databases was performed in June 2017. We included full papers that met the following criteria: original research; English language; human studies; enrolling LUTS/BPO patients; reporting maximum urinary flow (Qmax), and detrusor pressure at maximum urinary flow (PdetQmax). The primary endpoint was variation in bladder outlet obstruction index (BOOI). Secondary endpoints were variations in Qmax and PdetQmax. RESULTS: Twenty-three studies involving 1044 patients were included in the final analysis. Eighteen, three, two, and one study evaluated the urodynamic outcomes of ABs, 5-ARIs, PDE5is, and phytotherapic compounds, respectively. BOOI, PdetQmax, and Qmax improved in a statistically significant manner in patients receiving ABs and in those receiving 5-ARIs. The overall pooled data showed a mean BOOI change of -15.40 (P < 0.00001) and of -10.55 (P = 0,004) for ABs and 5-ARIs, respectively. Mean PdetQmax and Qmax changes were:12.30 cm H2 O (P < 0.00001) and +2.27 ml/s (P < 0.00001) for ABs and -9.63 cm H2 O (P = 0.05), and +1.18 mL/s (P = 0.04) for 5-ARIs. PDE5is and phytotherapic compounds had no significant effects on urodynamic parameters. CONCLUSIONS: ABs and 5-ARIs efficiently improve BOOI in men with LUTS/BPO. Both treatments are associated with a clinically significant decrease in PdetQmax but only marginal improvements in Qmax.

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.

Long-term outcomes of TOT and TVT procedures for the treatment of female stress urinary incontinence: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESES: One of the most relevant topics in the field of pelvic floor dysfunction treatment is the long-term efficacy of surgical procedures, in particular, the use of prosthesis. Hence, a systematic review and meta-analysis was conducted to evaluate the long-term effectiveness and safety of midurethral sling (MUS) procedures for stress urinary incontinence (SUI), as reported in randomised controlled trials (RCTs) and non-randomised studies. METHODS: This systematic review is based on material searched and obtained via PubMed/Medline, Scopus, and the Cochrane Library between January 2000 and October 2016. Peer-reviewed, English-language journal articles evaluating the long-term (≥5 years) efficacy and safety of MUS in women affected by SUI were included. RESULTS: A total of 5,592 articles were found after the search, and excluding duplicate publications, 1,998 articles were available for the review process. Among these studies, 11 RCTs (0.6%) and 5 non-RCTs (0.3%) could be included in the qualitative and quantitative synthesis. Objective and subjective cumulative cure rates for retropubic technique (TVT) and transobturator tape (TOT; both out-in and in-out) were 61.6% (95% CI: 58.5-64.8%) and 76.5% (95% CI: 73.8-79.2%), and 64.4% (95% CI: 61.4-67.4%) and 81.3% (95% CI: 78.9-83.7%) respectively. When considering TOT using the out-in technique (TOT-OI) and TOT using the in-out technique (TVT-O) the objective and subjective cumulative cure rates were 57.2% (95% CI: 53.7-60.7%) and 81.6% (95% CI: 78.8-84.4%), and 68.8% (95% CI: 64.9-72.7%) and 81.3% (95% CI: 77.9-84.7%) respectively. Furthermore, this article demonstrates that both TVT and TOT are associated with similar long-term objectives (OR: 0.87 [95% CI: 0.49-1.53], I 2 = 67%, p = 0.62) and subjective (OR: 0.84 [95% CI: 0.46-1.55], I 2 = 68%, p = 0.58) cure rates. Similarly, no significant difference has been observed between TTOT-OI and TVT-O) in objective (OR: 3.03 [95% CI: 0.97-9.51], I 2 = 76%, p = 0.06) and subjective (OR: 1.85 [95% CI: 0.40-8.48], I 2 = 88%, p = 0.43) cure rates. In addition, this study also shows that there was no significant difference in the complication rates for all comparisons: TVT versus TOT (OR: 0.83 [95% CI: 0.54-1.28], I 2 = 0%, p = 0.40), TOT-OI versus TVT-O (OR: 0.77 [95% CI: 0.17-3.46], I 2 = 86%, p = 0.73). CONCLUSIONS: Independent of the technique adopted, findings from this systematic review and meta-analysis suggest that the treatment of SUI with MUS might be similarly effective and safe at long-term follow-up.

Urodynamics useless before surgery for female stress urinary incontinence: Are you sure? Results from a multicenter single nation database.

AIMS: The role of urodynamics (UDS) before surgery for stress urinary incontinence (SUI) remains a debated issue in female urology as well as in urogynaecology and it has been recently questioned on the basis of data coming from selected population of patients defined as "uncomplicated." The aim of this study was to investigate the percentage of "uncomplicated" patients undergoing urodynamic evaluations in six referral Italian centers. The secondary aim was to assess the prevalence of women, for whom the urodynamic evaluation could add new information to the pre-urodynamic picture and in how many cases these findings had a significant impact on patient management. METHODS: The data of women who underwent urodynamic evaluation prior to surgery for stress urinary incontinence between 2008 and 2013 were retrospectively analyzed. According to the definition of the Value of Urodynamic Evaluation (ValUE) trial criteria, patients presenting with SUI were classified as "uncomplicated" or "complicated." Urodynamic observations were then compared with pre-urodynamic data. RESULTS: Overall, 2,053 female patients were considered. Only 740/2,053 (36.0%) patients were defined "uncomplicated" according to the definition used in the ValUE trial. The urodynamic observations were not consistent with the pre-urodynamic diagnosis in 1,276 out of 2,053 patients (62.2%). Voiding dysfunctions were urodynamically diagnosed in 394 patients (19.2%). Planned surgery was cancelled or modified in 304 patients (19.2%), due to urodynamic findings. CONCLUSIONS: "Uncomplicated" patients represent a minority among female SUI patients evaluated before surgery. In "complicated" patients, the role of urodynamic has not been challenged yet and UDS seems still mandatory. Neurourol. Urodynam. 35:809-812, 2016. © 2015 Wiley Periodicals, Inc.
