BackgroundBotulinum toxin was first described in 1895. It is a potent neurotoxin released by clostridium, a gram-negative, anaerobic, rod-shaped bacterium. Initially, it was considered to be the cause of life-threatening disease. However, research demonstrated it to be a novel and effective therapy in managing a range of diseases, including some that affect the urinary bladder. It was approved by the Food and Drug Administration (FDA) in 1898. ObjectivesThis study aimed to evaluate the long-term effects of intravesical botulinum toxin A (BTA) injections in patients with an indwelling long-term catheter for detrusor overactivity. The patients selected for this study were experiencing significant catheter-associated symptoms such as bypassing, bladder spasms, intractable pain, blockages, and recurrent infections. MethodA retrospective cohort study was conducted in patients that received intravesical BTA after the failure of symptom management using oral anticholinergic and beta 3-adrenocepter agonist. A group of 12 patients was identified, and they were followed up in the clinic after receiving treatment. ResultsAll of the patients included in this study had relief of their symptoms following administration of intravesical BTA. Almost 58% (n = 7) of patients required 3 or fewer treatments with BTA to gain symptom control, with the remaining patients gaining control after 4 treatments. There were no significant adverse events reports with only mild and temporary side effects, such as haematuria, experienced. ConclusionThis study demonstrated that intravesical BTA can significantly improve symptoms associated with long-term indwelling catheters and may help avoid more complex and invasive interventions.

BackgroundMyeloid sarcoma is a rare extramedullary tumour of immature granulocytes, most commonly involving the skin, bone, lymph nodes, and soft tissue. It is usually associated with a diagnosis of relapsed or de novo acute myeloid leukaemia, acute lymphoblastic transformation of a myelodysplastic/myeloproliferative neoplasm, or can occur as isolated myeloid sarcoma.Case reportA 66-year-old female with a 7-year history of stable chronic myelomonocytic leukaemia presents with urgency, frequency, dysuria symptoms, and without new constitutional symptoms. She is found to have atypical, multifocal lesions on the right posterolateral wall of the bladder with associated hydronephrosis. Pathology reveals the diagnosis as myeloid sarcoma; surprisingly, bone marrow evaluation does not show evidence of acute leukaemic transformation.ConclusionsMyeloid sarcoma occurring in patients with chronic myelomonocytic leukaemia is extremely rare, and there are no cases reported in the English literature of these patients developing lesions in the bladder. The urological manifestations of an underlying haematological malignancy are best managed with a combination of systemic chemotherapy and allogeneic stem cell transplant, and in this case, the only surgical intervention required was ureteric stenting and tissue biopsy. Although rare, it is essential to consider alternative diagnoses when confronted with an atypical bladder tumour; failure to do so may result in patient harm by exposure to unnecessary intervention and delay to potentially curative treatment.

Introduction: The coronavirus (COVID-19) pandemic of 2020 had a major impact on NHS services. From the 23rd of March 2020, the Urology Department in Basingstoke initiated telephone-led consultation clinicsinstead of face-to-face outpatient appointments, in accordance with U.K. guidance.Objectives: To evaluate patient experience and satisfaction following the introduction of remote (telephone) consultations during the COVID-19 pandemic.Patients and methods: The first 200 remote patient appointments between the 30th of March 2020 and the 16th of April 2020 were sent a postal questionnaire (19 questions relating to their experience and level of satisfaction with the interaction). Telephone consultations were conducted by 6 consultants, 3 registrars, and 2 specialist nurses. The patients were not prewarned to expect a questionnaire after the remote ap-pointment. The associated cost saving resulting from a switch from face-to-face appointments to remote telephone appointments was also calculated.Results: 100 out of the 200 patients responded within 1 month (response rate 50%). A total of 44% of the patients were new referrals, while 56% were follow-ups. Overall, the feedback was positive regarding the telephone consultation, with 88% rating the care received as excellent or very good. In addition, 90% would recommend a telephone consultation to family and friends. However, 35% would prefer in the future to have another telephone consultation rather than face-to-face consultation, with 46% preferring a face-to-face appointment in the future and 19% unsure. For new patients, the proportion wishing to have a face-to-face appointment, in the end, was unsurprisingly higher than it was for those undergoing a follow-up (39% vs. 7 %). In these 2 weeks, the cost reduction to the NHS from shifting from face-to-face consultation to telephone consultation was estimated to be £6500.Conclusions: Telephone urology clinics are a satisfactory alternative to face-to-face appointments for many of our patients now and beyond the COVID-19 pandemic. They are efficient, cost-effective, and feasible to undertake urological consultation and can be implemented successfully in selected patients. The feedback from this questionnaire would suggest that priority should be given to face-to-face appointments for new patients and for complex follow-up appointments. Telephone follow-up appointments, however, are a good approach for the majority of patients.

Background and ObjectiveIn recent years, GreenLight laser photoselective vaporisation of the prostate (GL-PVP) has emerged as the primary ablative surgical treatment option for symptomatic bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE). Unlike the reference procedure, monopolar-transurethral resection of the prostate (M-TURP), GL-PVP can be performed as a day case. As waiting list pressures continue to burden health boards across the UK, exacerbated by the COVID-19 pandemic, enhanced access to day case surgery to optimise patient flow is now of paramount importance. We evaluated the safety and feasibility of day case GL-PVP at our high-volume UK centre and identified predictors of a postoperative overnight stay. Material and MethodsWe performed a retrospective observational cohort study of all patients who underwent primary GL-PVP at a single institution between October 2016 and June 2021. All procedures were performed utilising the 180W GreenLight XPS™ laser therapy system. Various clinical, operative and functional data were collated, and outcomes were compared between patients who underwent day case surgery and those admitted overnight postoperatively. ResultsIn all, 538 patients underwent GL-PVP during the study period. Median patient age was 72 (interquartile range (IQR) 66–77), and median prostate volume was 62.5cc (IQR 45–90). Five hundred nineteen patients (96.5%) were discharged within 23 hours of admission, and 366 patients (68.0%) were managed as a true day case. Operative and functional outcomes were comparable between patients managed as a day case and those admitted overnight. There was higher patient-reported satisfaction and a lower rate of early hospital readmission in the day-case group. On univariate logistic regression analysis, patients aged ≥80 years (Odds Ratio 2.64 [95% Confidence Interval 1.65– 4.24], p = < 0.001), those with American Society of Anaesthesiologists (ASA) physical status classification score ≥3 (OR 1.92 [95% CI 1.33–2.78], p = < 0.001), those with prostate volume ≥80cc (OR 1.62 [95% CI 1.00–2.61], p = 0.05) and those in whom the operation time ≥60 minutes (OR 1.66 [95% CI 1.10–2.52], p = 0.02) were more likely to be admitted overnight following GL-PVP. On multivariate logistic regression analysis, age ≥80 (OR 2.64 [95% CI 1.47–4.73], p = 0.001) and ASA score ≥3 (OR 2.03 [95% CI 1.28–3.22], p = 0.003) remained predictive variables of an overnight stay. ConclusionFrom our observations of a large cohort of patients over a study period of almost five years, day case GL-PVP is a feasible concept and does not appear to compromise perioperative outcomes. With appropriate service redesign and optimisation of postoperative patient pathways, day case GL-PVP can be established in other centres and may have a role in alleviating waiting list pressures.
背景与目的近年来，绿光激光前列腺光选择性汽化(GL-PVP)已成为治疗良性前列腺增大(BPE)继发症状性膀胱出口梗阻(BOO)的首选消融手术治疗方法。与参考手术，单侧经尿道前列腺切除术(M-TURP)不同，GL-PVP可以作为一天的病例进行。由于COVID-19大流行加剧了等待名单的压力，英国各地的卫生委员会继续承受着压力，因此增加日间手术的机会以优化患者流量现在至关重要。我们在我们的英国大容量中心评估了日间病例GL-PVP的安全性和可行性，并确定了术后过夜的预测因素。材料和方法我们对2016年10月至2021年6月在一家机构接受原发性GL-PVP治疗的所有患者进行了回顾性观察队列研究。所有手术均采用180W GreenLight XPS™激光治疗系统。整理各种临床、手术和功能数据，比较日间手术患者和术后过夜住院患者的结局。结果538例患者在研究期间接受了GL-PVP治疗。患者年龄中位数为72岁(四分位间距(IQR) 66-77)，前列腺体积中位数为62.5cc (IQR 45-90)。519例(96.5%)患者在入院23小时内出院，366例(68.0%)患者被管理为真正的一天病例。手术和功能结果在日间和夜间住院的患者之间具有可比性。在日间病例组中，患者报告的满意度较高，早期再入院率较低。在单变量逻辑回归分析,患者年龄≥80岁(优势比为2.64(95%置信区间1.65 - 4.24),p = < 0.001),美国社会的这(ASA)身体状况分类评分≥3(或1.92 (95% CI 1.33 - -2.78), p = < 0.001),与前列腺体积≥80 cc(或1.62 (95% CI 1.00 - -2.61), p = 0.05)和那些在操作时间≥60分钟(或1.66 (95% CI 1.10 - -2.52), p = 0.02)更容易被承认GL-PVP后一夜之间。多因素logistic回归分析显示，年龄≥80岁(OR 2.64 [95% CI 1.47 ~ 4.73]， p = 0.001)和ASA评分≥3 (OR 2.03 [95% CI 1.28 ~ 3.22]， p = 0.003)仍是住院的预测变量。结论:从我们在近5年的研究期间对大量患者的观察来看，日间病例GL-PVP是一个可行的概念，并且似乎不会影响围手术期的预后。通过适当的服务重新设计和优化术后患者路径，可以在其他中心建立日病例GL-PVP，并可能在减轻等候名单压力方面发挥作用。

Introduction and Objectives: Renal papillary necrosis is one of the common causes of obstructive uropa-thy in diabetic patients. During removal of necrosed renal papilla, many patients were observed to have fluffy necrotic material in the ureter, and renal pelvis, and a few among them present again with recurrent episodes of obstructive uropathy and sepsis following DJ stent removal. Our study aimed to identify thesignificance of this fluffy necrotic material and its evaluation by histopathological examination (HPE). Materials and Methods: This is a prospective observational study done in our institute by compiling data of 56 patients admitted with obstructive uropathy secondary to renal papillary necrosis who underwent a protocol-based treatment from 2016 to 2019. All these patients underwent initial DJ stenting followed by check flexible ureteroscopy or nephroscopy after 6 weeks. The white, necrotic fluffy material collected during initial DJ stenting or with subsequent flexible ureteronephroscopy was sent for HPE. All these patients were followed up for 1-3 years. Results: Out of 56 patients, 15 patients had fluffy necrotic material in the bladder on initial cystoscopy, of which 1 patient was diagnosed with aspergillosis and 1 patient with candida infection on HPE. During check flexible ureteroscopy (FU), 19 patients had minimal burden of fluffy necrotic material in renal pelvis, of which one patient was diagnosed with aspergillosis, one with candida (same patient diagnosed on cystoscopy), and one patient with both aspergillus and candida colonies on HPE. 5 patients had the significant burden of fluffy necrotic material in the renal pelvis, requiring removal via percutaneous nephroscopic access. Among these 5 patients, 2 were diagnosed with aspergillosis and 1 with candida infection on HPE. A total of 32 patients had single papilla, and 24 had multiple papillae in the pelvicalyceal system. 5 out of 7 patients with positive fungal pathology had negative fungal cultures. Compared to our historical data of 4% mortality and 22% recurrent obstructive uropathy in the 3 years preceding the adoption of this protocol, with the present protocol, no patient developed recurrent pyelonephritis during follow-up of 1–3 years after DJ stent removal following complete evacuation of necrotic material and appropriate antifungal treatment. Conclusion: This study highlights the need for check ureterorenoscopy and removal of all necrotic papillae and debris to establish a microbiological and histopathological diagnosis along with proper antifungal treatment to prevent episodes of recurrent pyelonephritis and obstructive uropathy.

Introduction: Elective waiting lists have become more stretched because of the COVID-19 pandemic and patients have evidently been waiting longer for treatment. Patients with high-risk bladder cancer require timely treatment and there is strong evidence to suggest that delay in treatment contributes to a risk of disease progression, metastases and death. Studies have shown that bladder tumour appearances at flexible cystoscopy (FC) can accurately predict high-risk disease on histopathology following transurethral resec-tion. An opportunity for service improvement resulted in a review of the practice followed by the authors and the development of a risk stratification tool for the haematuria clinic which aimed to prioritise thepathway of those with high-risk disease.Materials and methods: A risk stratification tool was developed for patients with newly diagnosed bladder tumours at the haematuria clinic. A tumour assessment carried out at FC is used to predict patients with high-risk disease, thus allowing those patients to be prioritised over those with low-risk disease on the waiting list. It also includes a reminder to request staging investigations for those with suspected high-risk disease. A closed loop audit was carried to review the following: the quality of tumour risk assessment at the haematuria clinic; time from FC to transurethral resection of bladder tumour (TURBT); concordance between tumour assessment at FC and histopathology after TURBT; efficiency of arranging early staging investigations for those with suspected high-risk bladder cancer; time from FC to staging CT scan. Results: A risk assessment was carried out for 93% of patients in the second cycle compared with 40% in the first cycle. Concordance was noted in 83% of those with confirmed high-risk non-muscle invasive bladder cancer (NMIBC) and 83% of muscle invasive bladder cancer (MIBC) in the first cycle, and in 100% of patients with high-risk NMIBC and MIBC in the second cycle. The interval from FC to TURBT decreased from 27 days in the first cycle to 21 days in the second cycle in those with high-risk NMIBC, and from 27 to 13 days in those with MIBC. Time from FC to staging CT for patients with high-risk bladder cancer was 6 days in the first cycle and 3 days in the second cycle if the request was made from the haematuria clinic. If the CT scan was requested later, the interval increased to 39 days in the first cycle and 22 days in the second cycle.Conclusion: There is a high degree of concordance between tumour risk assessment at FC and final pathol-ogy following TURBT which is supported by several series. Performing risk assessment and requesting staging investigations at the haematuria clinic for patients with newly diagnosed high-risk bladder cancer can minimise delays in their treatment pathway and improve patient outcomes.

Background: In Africa, lithogenesis was initially considered rare and it was mostly caused by infections. Recent studies suggest that obesity, change in dietary habits (milk, dairy products) and hot climate can contribute to an increase of the condition in the region. Over the past decades, the management of upper urinary tract urolithiasis has evolved significantly with minimally invasive techniques. The challenge for sub-Saharan countries is related with the acquisition and the training for minimally invasive treatment. In fact, open surgery has less indications in the management of urolithiasis. The aim of this study is to evaluate the preliminary results of ureteroscopic laser treatment for upper urinary tract lithiasis in our hospital. Methods: This was a prospective, descriptive study realized between June 2016 and December 2018. The patients included were those who had ureteroscopic laser treatment for upper urinary tract lithiasis. The treatment was performed under general anesthesia by two surgeons. The studied parameters were: age, sex, patient medical history, comorbidities, renal function, cytobacteriological examination of urine, characteristics of lithiasis, intra and postoperative complications (using the Clavien–Dindo classification), ureteroscopic laser failures (frequency and causes). Success of treatment was defined by: the absence of a residual fragment at the renal and ureteral level or of a residual fragment <4 mm at the renal level on the control imaging. Data analysis was done with IBM SPSS Statistic 23 software. Statistical significance was considered when P < 0.05. Results: This study involved 43 patients. The mean age was 40.84 years ± 15.33 years. The age group between 30 and 39 years was predominant. The sex ratio was 1.26. Nephritic colic was the circumstance of discovery in 93.02%. The Uro-CT scan performed in all our patients, revealed kidney stones in 16.3% and ureteral stones in 83.7%. The right side was the most involved in 55.8%. The mean size of the stones was 12.2 mm ± 4.89 at the renal level and 12.05 mm ± 5.54 at the ureteral level. The semi-rigid ureteroscope was used in 88.37% and the flexible ureteroscope in 11.63%. The lithiasis was visualized in 74.4% of cases. Laser fragmentation was performed in 69.77% of cases. A J stent was placed after 72.1% of cases. Pelvic ureteral stripping and pelvic ureteral aspiration were realized in one case each. Acute pyelonephritis (ANP) was observed in 25.6% of patients. There were 75% fragment free at postoperative control. Any factors associated with treatment failure were not found.

BackgroundThe coronavirus disease (COVID-19) had so far claimed more than 600 000 lives worldwide. Many urgent and elective surgeries were postponed to cope with the pandemic, with the latest data found a substantial postoperative mortality risk (25.6%, 18.9%) after an emergency and elective surgery, respectively. Our institution was one of the first few in the country to offer essential elective surgery using a “COVID-free” designated site during the start of the pandemic. This study aims to analyze the clinical outcomes of patients who underwent essential elective procedures during the virus outbreak in the UK. MethodsRetrospective analysis of outcomes of all patients who had undergone urgent elective and cancer surgery, from 30th March 2020 to 21st May 2020, using an implemented “Super Green Pathway.”The primary endpoints were 30 days mortality and COVID-related morbidities, and the secondary end-points were surgically related complications and oncological outcomes. ResultsA total of 92 patients (Male: 45%; Female: 55%) across 5 surgical specialties were identified. There was no record of mortality in our cohort. Only 1 patient was tested positive for SARS-CoV-2, 18 days after the initial operation without any pulmonary complications. There were 7 postoperative surgical complications managed at the acute hospital site. The waiting time for surgery ranges from 6 to 191 days, mean of 30 days, and a median of 23 days. ConclusionIt is possible to mitigate the high mortality risk of post-operative complications associated with COVID-19, with no delay to essential surgeries for cancer patients, thus delivering safe practice during the pandemic.
