Interventions to improve tolerability of local anesthetic intradetrusor Botulinum toxin injections: A systematic review.

INTRODUCTION: Intradetrusor BotulinumtoxinA (BTA) injections are recommended for patients with overactive bladder (OAB) refractory to lifestyle changes and medical intervention. It is preferable to perform injections using a flexible cystoscope under local anesthetic (LA) rather than under spinal or general anesthetic owing to the associated anesthetic risks, increased costs, and need for repeated inpatient admission. Injections under LA can be difficult to tolerate for some patients. This review aims to assess interventions that may improve the tolerability of intradetrusor BTA injections under LA. METHODS: A systematic review was performed using Ovid of Embase + Embase classic and MEDLINE® ALL in November 2021. Articles were included if they reported objectively measured pain scores during LA intradetrusor BTA injections for refractory OAB. The risk of bias was assessed using Cochrane risk of bias tools. Meta-analysis was not performed owing to the heterogeneity of outcome measures. RESULTS: Ten studies were included in this review with a total of 429 participants. The review identified alkalinized lidocaine, electromotive drug administration (EMDA), opiate suppositories, lidocaine bladder instillations, number of injections, and dose of BTA as interventions aimed at improving tolerability. CONCLUSION: EMDA of intravesical alkalinized lidocaine, intravesical, alkalinized lidocaine without EMDA, and a reduction in the number of injection site were all associated with improvements in patient tolerability during LA BTA injections. Further research should address which subgroups of patients find the procedure most painful and would benefit most from these interventions.

Reducing last-minute cancellations of elective urological surgery-effectiveness of specialist nurse preoperative assessment.

Last-minute cancellations in urological surgery are a global issue, resulting in the wastage of resources and delays to patient care. In addition to non-cessation of anticoagulants and inadequately treated medical comorbidities, untreated urinary tract infections are a significant cause of last-minute cancellations. This study aimed to ascertain whether the introduction of a specialist nurse clinic resulted in a reduction of last-minute cancellations of elective urological surgery as part of our elective recovery plan following the Coronavirus disease 2019, the contagious disease caused by severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2 pandemic. A specialist urology nurse-led clinic was introduced to review urine culture results preoperatively. Specialist nurses contacted patients with positive urine cultures and their general practitioners by telephone and email to ensure a minimum of 2 days of 'lead-in' antibiotics were given prior to surgery. Patients unfit for surgery were postponed and optimized, and vacant slots were backfilled. A new guideline was created to improve the timing and structure of the generic preassessment. Between 1 January 2021 and 30 June 2021, a mean of 40 cases was booked each month, with average cancellations rates of 9.57/40 (23.92%). After implementing changes on 1 July 2021, cancellations fell to 4/124 (3%) for the month. On re-audit, there was a sustained and statistically significant reduction in cancellation rates: between 1 July 2021 and 31 December 2021 cancellations averaged 4.2/97.5 (4.3%, P < .001). Two to nine (2%-16%) patients were started on antibiotics each month, while another zero to two (0%-2%) were contacted for other reasons. The implementation of a specialist urology nurse-led preassessment clinic resulted in a sustained reduction in cancellations of last-minute elective urological procedures.

Age-related urologic problems in the complex urologic patient.

PURPOSE: Improved medical care throughout childhood and adolescence has enabled patients with complex urological abnormalities to live longer into adulthood. These patients are now at risk of developing common, age-related, urological conditions. This review aims to review existing data and make recommendations in areas where expert opinion is currently lacking METHODS: This review represents the joint SIU-ICUD (Société Internationale d'Urologie-International Consultation on Urological Disease) consultation on congenital lifelong urology. The results of this analysis were first presented at a joint consultation of the ICUD and SIU at the 2018 SIU annual conference in Seoul, South Korea. RESULTS: BPH may present differently in patients with neurogenic bladder. Thorough assessment of neurological status, bladder and sphincter function is required before offering any bladder outlet surgery. Prostate specific antigen screening should be offered to men aged 50-69 with neurogenic bladders if they have good life expectancy. Multi-parametric MRI and transperineal biopsy would be the investigations of choice if feasible. Surgery for localized disease should only be done by surgeons with the relevant expertise. Bladder cancer in this patient group is more likely to present at a later stage and have a worse prognosis. Parenthood is achievable for most, but often requires assistance with conception. Pregnant women who have had previous urogenital reconstructive surgery should be managed in appropriate obstetric units with the involvement of a reconstructive urologist. CONCLUSIONS: Most evidence regarding complex urogenital abnormalities comes from the pediatric population. Evidence regarding common, age-related urological issues is generally from the 'normal' adult population. As patients with complex congenital urological conditions live longer, more data will become available to assess the long-term benefits of intervention.

Initial outcomes of local anaesthetic freehand transperineal prostate biopsies in the outpatient setting.

OBJECTIVES: To evaluate the histopathological outcomes, morbidity and tolerability of freehand transperineal (TP) prostate biopsies using the PrecisionPoint™ access system (Perineologic, Cumberland, MD, USA) under local anaesthetic (LA) in the day surgery and outpatient environments, as systematic and targeted biopsies can be taken with the potential for reduced morbidity, particularly sepsis. PATIENTS AND METHODS: In all, 176 patients underwent freehand TP prostate biopsies from May 2016 to November 2017. The procedure was carried out either under LA alone or with the addition of sedation. Magnetic resonance imaging (MRI) scans were reported using the Prostate Imaging-Reporting and Data System (PI-RADS), version 2. Tolerability was assessed using a visual analogue scale pain score for each procedural stage. Histopathological outcomes and complications were recorded. RESULTS: The mean (range) age was 65 (36-83) years, median (range) prostate-specific antigen level was 7.9 (0.7-1374) ng/mL, and the mean (range) prostate volume 45 (15-157) mL. Biopsies were taken under LA alone (160 patients, 90%) or under LA with sedation (16, 9%). The main indication for biopsy was primary diagnosis (88.6%). In all, 91 (52%) patients underwent systematic TP biopsies (mean 24.2 cores). Cognitive MRI-targeted biopsies alone were performed in 45 patients (26%; mean 6.8 cores), and 40 (23%) had both systematic and target biopsies (mean 27.9 cores). Of the 75 patients who had primary systematic biopsies alone, 46 (61%) were positive, and 28/46 (60.9%) were diagnosed with clinically significant disease (Gleason ≥3+4). VAS pain scores were greatest during LA administration. There were five complications (2.8%, Clavien-Dindo Grade I/II). No patients developed urosepsis. CONCLUSIONS: Freehand TP biopsies using the PrecisionPoint access system is a safe, tolerable and effective method for systematic and targeted biopsies under LA in the outpatient setting. It has replaced transrectal biopsies in our centre and has potential to transform practice.

Linking the evidence between urinary retention and antipsychotic or antidepressant drugs: A systematic review.

AIMS: Urinary retention (UR) occurs in patients on antipsychotic and antidepressant medication despite no apparent underlying urological cause. This review was undertaken to ascertain which of these medications are associated with UR and how often. METHODS: A systematic literature search for evidence on antipsychotic and antidepressant medications and UR was completed in June 2015 using Scopus, Pubmed, Web of Science, and the Cochrane library. Search terms included urinary retention, antidepressants and antipsychotics as well as individual drug names. Filters used were: humans and English language. PRISMA guidelines were employed. RESULTS: Out of 614 articles initially identified, one meta-analysis, five RCT's, five cohort studies and 27 case reports were finally included. There was a wide range of definitions of UR. Studies which appropriately defined UR revealed it occurred in 1/21 patients on ziprasidone (an atypical antipsychotic), 17.6% of those on imipramine but only 0.1% of those on all tricyclic antidepressants analysed together. It was not reported in any of the 1,139 patients given duloxetine (a combined serotonin and noradrenaline reuptake inhibitor). It was reported in 0.025% of patients on selective serotonin reuptake inhibitors. UR was also reported in patients on typical antispychotics, selective noradrenaline reuptake inhibitors but the studies did not define UR. The majority of case reports reported an improvement in UR on discontinuation or dose reduction. CONCLUSION: Antipsychotics and antidepressants interact with the urinary system in many ways. Clinicians treating acute UR need to keep in mind the role of antipsychotic and antidepressants as a precipitating cause. Neurourol. Urodynam. 35:866-874, 2016. © 2015 Wiley Periodicals, Inc.

Late urological manifestation of stress incontinence surgery.

The Stamey procedure was a popular procedure for female stress incontinence practiced widely in the 1980s before it was abandoned owing to high complication rates. The procedure aimed to suspend the bladder neck by placing two transvaginal Dacron buttress grafts either side of the bladder neck and suspending them with sutures passed through the retropubic space and tied suprapubically. Erosion of the graft into the bladder was a recognised complication. We report a case of an 84-year-old lady who presented with urinary symptoms forty years after an unspecified stress incontinence procedure. Imaging and cystoscopy revealed an eroded graft in her bladder wall. Further investigation revealed the graft was a Dacron buttress from a Stamey procedure. This case highlights the importance of having a working knowledge of historical techniques that may present with complications many years later and recognising the symptoms that should prompt early investigation.

The Postural Tachycardia Syndrome (PoTS) Bladder-Urodynamic Findings.

OBJECTIVE: To evaluate the urodynamics (UDS) of patients with postural tachycardia syndrome (PoTS). METHODS: Patients with a confirmed diagnosis of PoTS referred by the department of neuro-cardiology to the neuro-urology were identified and their UDS were retrospectively reviewed. RESULTS: In total, 50 patients (47 = 94.0% female) with confirmed PoTS and available UDS were identified. Mean age of females and males was 32.4 and 28.2 years, P = .15. Intermittent self-catheterisation was being used by 15/47 (31.9%) females at assessment. Detrusor overactivity was observed in 6 females (12.8%) (all at end fill and associated with urgency). In total, 14 (29.8%) females had no sensation of filling. No patients had an "unsafe" bladder. In total, 15/47 (31.9%) of women were unable to void with UDS catheters. Straining was reported in 22/35 (68.8%) of females. The female bladder outflow obstruction index = PDetQmax - 2.2(Qmax) was over 5 in 10/28 (35.7%) and over 18 in 5 (17.9%). The bladder contractility index = PDetQmax + 5Qmax was under 100 in 18/28 (28.6%) women. CONCLUSION: The UDS of patients with "PoTS bladder" often demonstrate a poorly sensate but stable and safe bladder with functional obstruction and impaired bladder contractility that may necessitate straining or intermittent self-catheterisation.

Onabotulinum toxin A Injections in Men With Refractory Idiopathic Detrusor Overactivity.

OBJECTIVE: To establish the effectiveness and safety profile of Onaboulinum toxin A (BTX-A) in men with idiopathic detrusor overactivity and compare with the outcomes observed in women. Several randomized trials have demonstrated the effectiveness of intradetrusor BTX-A injections in improving symptoms and quality of life in patients with overactive bladder (OAB) symptoms. Most trials however contained relatively few men or excluded men altogether. MATERIALS AND METHODS: Data patient undergoing BTX-A for refractory OAB with idiopathic detrusor overactivity on urodynamics were extracted from our center's prospectively maintained database. Incontinence impact questionnaire-7 and urogenital distress inventory-6 scores were collected at baseline and 4-12 weeks together with data regarding urinary retention requiring clean intermittent self-catheterization (CISC) and urinary tract infection (UTI). Urodynamic studies were assessed where available to see if voiding dysfunction and CISC were predictable. RESULTS: Sixty-five men received 133 BoNT-A treatments in the 15-year period representing 27.8% of those with refractory OAB. Baseline urogenital distress inventory-6 and incontinence impact questionnaire-7 fell by 4.2 (P = .00) and 6.0 (P = .00) points for men and by 6.0 (P = .00) and 11.1 (P = .00) for women, respectively. De novo CISC was required in 46 (42.6%) men and 107 (35.3%) women (P = .10). UTI was reported in 36 (29.0%) men and 86 (27.0%) women (P = .73). The bladder outflow obstruction index and the bladder contractility index did not reliably predict CISC requirement. CONCLUSION: Men with refractory OAB experience significant improvement in quality of life scores following BTX-A, though the benefit appears greater in women. The requirements for CISC and UTI rates were similar between sexes.

Early-Medium-Term Outcomes of Primary Focal Cryotherapy to Treat Nonmetastatic Clinically Significant Prostate Cancer from a Prospective Multicentre Registry.

BACKGROUND: Focal cryotherapy can be used to treat patients with clinically significant nonmetastatic prostate cancer to reduce side effects. OBJECTIVE: Early-medium-term cancer control and functional outcomes. DESIGN, SETTING, AND PARTICIPANTS: A prospective registry-based case series of 122 consecutive patients undergoing focal cryotherapy between October 1, 2013, and November 30, 2016, in five UK centres. Median follow-up was 27.8mo [interquartile range (IQR) 19.5-36.7]. A total of 35 patients (28.7%) had National Comprehensive Cancer Network (NCCN) high risk and 87 (71.3%) had intermediate risk disease. Risk and zonal stratification included multiparametric magnetic resonance imaging (mpMRI) with targeted and systematic biopsies, or transperineal mapping biopsies. INTERVENTION: Focal cryoablation of MR-visible tumours. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Follow-up involved prostate-specific antigen (PSA) monitoring, mpMRI, and for-cause biopsies. Primary outcome was failure-free survival (FFS), defined as transition to radical, whole-gland, or systemic therapy, or metastases/death. Secondary outcomes included adverse events and functional outcomes. RESULTS AND LIMITATIONS: A total of 80 (65.6%) had anterior ablation, 23 (19.7%) combined posterior and anterior ablation, and two (1.6%) posterior ablation alone (SeedNet or Visual-ICE, BTG plc). Median age was 68.7yr (IQR 64.9-73.8) and preoperative PSA 10.8ng/ml (IQR 7.8-15.6). Overall FFS at 3yr was 90.5% [95% confidence interval (CI) 84.2-97.3]. When stratified for the NCCN risk group, 3-yr outcomes were 84.7% (95% CI 71.4-100) in high risk and 93.3% (95% CI 86.8-100) in intermediate risk. At last follow-up, incontinence defined as any pad use was 0/69 (0%) and erectile dysfunction (defined as erections insufficient for penetration) was 5/31 (16.1%). Limitations include lack of long-term outcomes. CONCLUSIONS: Focal cryotherapy primarily for anterior intermediate and high-risk prostate cancer results in good rates of cancer control and low rates of treatment-related side effects. PATIENT SUMMARY: In this multicentre study of 122 patients undergoing focal cryotherapy for medium- to high-risk prostate cancer, at 3yr, no patient died from their cancer whilst failure-free survival, was approximately 90%. None of the patients needed pads for managing urine leakage, although 16% had erection problems.

A comparison of time taken to return to baseline erectile function following focal and whole gland ablative therapies for localized prostate cancer: A systematic review.

OBJECTIVES: To systematically review erectile function (EF) outcomes following primary whole gland (WG) and focal ablative therapies for localized prostate cancer to ascertain whether the treatment modality or intended treatment volume affects the time taken to recover baseline EF. METHOD AND MATERIALS: A systematic review was performed according to the preferred reporting items for systematic review and meta-analysis statement. Inclusion criteria were men with localized prostate cancer treated with primary, ablative therapy. Primary outcome was the return to baseline EF measured with objective, validated symptoms scores. Secondary outcome was use of phosphodiesterase inhibitors or erectile aids. Meta-analysis was not performed owing to heterogenous outcome measures. RESULTS: Of 222 articles identified in February 2017, 55 studies which reported EF after ablative therapy were identified but only 17 used validated outcome measures and met inclusion criteria. WG cryotherapy was used in 2 studies, WG high-intensity focused ultrasound (HIFU) in 5, focal cryotherapy in 2, focal HIFU in 3, focal phototherapy or laser therapy in 4, vascular-targeted photodynamic therapy in 3, and irreversible electroporation in 2. WG cryotherapy was associated with a significant decline in EF at 6 months with minimal improvement at 36 months. Baseline IIEF-15 of patients undergoing focal HIFU fell 30 points at 1 month but returned to baseline by 6 months. The remaining focal therapies demonstrated minimal or no effect on EF, but the men in these studies had small foci of disease. The review is limited by lack of randomized studies and heterogenous outcome measures. CONCLUSIONS: Most studies assessing the outcomes of focal therapy on sexual function were not of high quality, used heterogenous outcomes, and had relatively short follow up, highlighting the need for more robustly designed studies using validated patient reported outcome measures  for comparison. However, FT in general resulted in less effect on EF than WG ablation.

Promoting vision and hearing aids use in an intensive care unit.

Vision and hearing impairments have long been recognised as modifiable risk factors for delirium.[1,2,3] Delirium in critically ill patients is a frequent complication (reported as high as 60% to 80% of intensive care patients), and is associated with a three-fold increase in mortality and prolonged hospital stay.[1] Guidelines by the UK Clinical Pharmacy Association recommend minimising risk factors to prevent delirium, rather than to treat it with pharmacological agents which may themselves cause delirium.[4] To address risk factors is a measure of multi-system management, such as sleep-wake cycle correction, orientation and use of vision and hearing aids, etc.[5] We designed an audit to survey the prevalence and availability of vision and hearing aids use in the intensive care unit (ICU) of one university hospital. The baseline data demonstrated a high level of prevalence and low level of availability of vision /hearing aid use. We implemented changes to the ICU Innovian assessment system, which serves to remind nursing staff performing daily checks on delirium reduction measures. This has improved practice in promoting vision and hearing aids use in ICU as shown by re-audit at six month. Further amendments to the Innovian risk assessments have increased the rate of assessment to 100% and vision aid use to near 100%.

Using imaging biomarkers to improve the planning of radical prostatectomies.

OBJECTIVES: This exploratory pilot study aimed to evaluate whether adding imaging biomarkers to conventional staging improves complete excision rates after undergoing radical prostatectomy (RP) in the United Kingdom for patients who have not undergone population prostate specific antigen screening. We primarily considered estimates of lesion volume and location based on computer-aided analysis of ultrasound (US) raw radiofrequency (RF) data acquired during trans-rectal ultrasound. The imaging analysis device used had been shown to accurately detect tumor loci within the prostate in previous studies. METHODS AND MATERIALS: US raw RF data were collected from motorized trans-rectal ultrasound of 68 consecutive men with operable prostate cancer. In this cohort (group 1), locations and volume measurements of lesions suspected of harboring cancer on US raw RF data analysis by prostate HistoScanning, were added to conventional presurgical staging.The unexposed control group comprised 100 men who underwent conventional presurgical staging only (group 2): 50 were operated before and 50 operated after group 1 recruitment. Changes to pre-operative surgical planning and positive lateral margins of RP prostate pathological specimens were the primary outcomes. Data were collected using a Microsoft Excel database and analyzed using Stata. RESULTS: Baseline demographics were comparable. In group 1, consideration of the additional imaging biomarkers led to changes in 27 (19.9%) operative surgical plans. Absolute rate reduction of a positive surgical margin (PSM) attributable to the imaging-biomarkers was 13.3% (P = 0.029). For stage pT3, PSM rate was reduced from 45.8% (n = 44) to 21.2% (n = 11) (P = 0.0028). CONCLUSIONS: Obtaining quantitative measurements of preoperative imaging biomarkers appears to improve PSM rates of patients undergoing RP. The greatest PSM rate reduction was observed for pT3 tumors.
