ABSTRACT
OBJECTIVES: To observe the clinical efficacy of moxibustion combined with western medication on ureteral stent-related symptoms after ureteroscopic lithotripsy (URL). METHODS: One hundred and fifty patients with upper urinary tract calculus implanted with ureteral stents after URL were randomly divided into a moxibustion group (50 cases, 1 case dropped out), a placebo moxibustion group (50 cases, 3 cases dropped out) and a blank control group (50 cases). No intervention was performed in the blank control group. On the basis of oral administration with tamsulosin hydrochloride sustained release capsule (starting from the first day after surgery, once a day, 0.2 mg each time, continuously for 4 weeks), in the moxibustion group, moxibustion was operated at Guanyuan (CV 4) and bilateral Shenshu (BL 23); the sham-moxibustion was delivered at the same acupoints in the placebo moxibustion group, once daily, 6 times a week, for 15 min in each treatment. The duration of treatment was 4 weeks. Before treatment, and after 1, 2 and 4 weeks of treatment, the scores of lower urinary tract symptoms, body pain, general health, work performance and satisfaction of sexual matters were compared among the 3 groups. The tract calculus clearance rate, urinary infection and the oral administration of painkillers were compared after 4 weeks of treatment in the 3 groups. RESULTS: The scores of lower urinary tract symptoms, body pain and general health after 1 week of treatment, and the scores of lower urinary tract symptoms, body pain, general health and work performance after 2 and 4 weeks of treatment were lower than those before treatment in the 3 groups (P<0.01). The scores of lower urinary tract symptoms and body pain in the moxibustion group after 1, 2 and 4 weeks of treatment were lower than those in the blank control group and the placebo moxibustion group (P<0.01, P<0.05) respectively. The score of general health in the moxibustion group was lower than that in the blank control group after 1 week of treatment (P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 2 and 4 weeks of treatment (P<0.01, P<0.05). Regarding the score of work performance, it was lower in the moxibustion group after 1 and 2 weeks of treatment compared with those in the blank control group (P<0.05, P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 4 weeks of treatment (P<0.01, P<0.05). The tract calculus clearance rate in the moxibustion group was 95.9% (47/49), higher than that in the blank control group (80.0%, 40/50, P<0.05). The proportion of oral administration of painkillers in the moxibustion group (28.6%, 14/49) and the placebo moxibustion group (40.4%, 19/47) was lower than that in the blank control group (76.0%, 38/50, P<0.01) respectively. CONCLUSIONS: Moxibustion combined with western medication relieves lower urinary tract symptoms and body pain, and accelerate the recovery of general health and work performance in the patients after URL.

PURPOSE: To assess the safety and effectiveness of the 4.5/6.5 Fr ureteroscopic laser lithotripsy (URSL) under topical intraurethral anesthesia (TIUA) compared to spinal anesthesia (SA). METHODS: A retrospective study was conducted on 47 (TIUA: SA = 23:24) patients receiving 4.5/6.5 Fr URSL from July 2022 to September 2022. For the TIUA group, atropine, pethidine, and phloroglucinol were used apart from lidocaine. In the SA group, patients received lidocaine and bupivacaine. We compare the two groups including stone-free rate (SFR), procedure time, anesthesia time, overall operative time, hospital stay, anesthesia failure, intraoperative pain, need for additional analgesia, cost, and complications. RESULTS: The conversion rate in the TIUA group was 4.35% (1/23). SFR was 100% in both groups. Surgical waiting time and anesthesia time were longer in the SA group (P < 0.001). There were no statistical differences in operational time and intraoperative pain. Patients developed grade 0-1 ureteral injuries. Post-surgical time out of bed was noticeably faster in the TIUA group (P < 0.001). The post-operative complication rate including vomiting and back pain was lower in the TIUA group (P = 0.005). CONCLUSION: TIUA had an equal surgical success rate and controlled patients' intraoperative pain as SA. It was superior in terms of TIUA's patient admission, waiting time for surgery, anesthesia time, post-operative time out of bed, low complications, and costs, especially for females.

PURPOSE: Vascular-targeted photodynamic therapy with the intravascular photosensitizing agent padeliporfin (WST-11/TOOKAD-Soluble) has demonstrated therapeutic efficacy as an ablative treatment for localized cancer with potential adaptation for endoscopic management of upper tract urothelial carcinoma. This Phase I trial (NCT03617003) evaluated the safety of vascular-targeted photodynamic therapy with WST-11 in upper tract urothelial carcinoma. MATERIALS AND METHODS: Nineteen patients underwent up to 2 endoscopic vascular-targeted photodynamic therapy treatments, with follow-up for up to 6 months. Patients who had residual or recurrent upper tract urothelial carcinoma (any grade/size) failing prior endoscopic treatment or unable or unwilling to undergo surgical resection were eligible for inclusion. The primary endpoint was to identify the maximally tolerated dose of laser light fluence. A dose escalation model was employed, with increasing light fluence (100-200 mW/cm) using a modified continual reassessment method. The secondary endpoint was treatment efficacy, defined by absence of visible tumor and negative urine cytology 30 days posttreatment. RESULTS: Fourteen (74%) patients received the maximally tolerated dose of 200 mW/cm, 2 (11%) of whom experienced a dose-limiting toxicity. The initial 30-day treatment response rate was 94% (50% complete, 44% partial). Eight patients underwent a second treatment, with a final observed 68% complete response rate. Leading toxicities were flank pain (79%) and hematuria (84%), which were transient. No ureteral strictures associated with treatment were identified during follow-up. CONCLUSIONS: Vascular-targeted photodynamic therapy with WST-11 has an acceptable safety profile with strong potential as an effective, kidney-sparing endoscopic management option for upper tract urothelial carcinoma. The recently initiated multicenter Phase 3 ENLIGHTED trial (NCT04620239) is expected to provide further evidence on this therapy.

OBJECTIVE: To comprehensively evaluate the long-term efficacy and safety of coated metal stent implantation for ureteroscopic lithotripsy related refractory ureteral stricture (URL-rUS). METHODS: Electronic medical records of 30 patients (31 affected renal units) receiving coated metal stent implantation for URL-rUS from Sept. 2018 to Aug. 2021 at Peking University People' s Hospital were reviewed for analysis. Coated metal stents were implanted in retrograde approach via ureteroscope. Last outpatient follow-up was set as endpoint. Baseline information, stricture characteristics and decompression strategy before coated metal stent implantation were retrospectively collected. Serum creatinine (Scr) concentration and renal pelvis width (RPW) were used as renal function indicators. Peri-operative and long-term complications and according outcomes were recorded. For the patients who had double J tubes implanted for drainage before operation, Ureteral Stent Symptom Questionnaire (USSQ) was applied to evaluate the stent-related discomforts and quality of life (QoL) before and after surgery. Data analysis was conducted with SPSS (version 25.0; SPSS, Chicago, IL, USA). RESULTS: Totally 30 patients with 31 affected renal units were included. All the patients previously underwent unsuccessful traditional endoscopic balloon dilation or endoureterotomy before receiving coated metal stent implantation. The mean age was (45.5±9.3) years old. The median follow-up time were 14 (6-36) months. All coated metal stents were successfully placed with a median duration of 60 (30-195) min. No severe peri-operative complications occurred. At endpoint, 28 (90.3%) sides of coated metal stents remained unobstructed with a longest indwelling time of 36 months. Causes of failures included stent migration (1 case, 3.2%), encrustation (1 case, 3.2%) and repeated stent related urinary tract infection (1 case, 3.2%). When compared with the baseline, significant reductions were observed in both Scr concentration and RPW at endpoint [(90.7±19.5) mmol/L vs. (83.1±18.5) µmol/L, P < 0.01, for Scr; (2.5±1.3) cm vs. (1.9±0.8) cm, P < 0.01, for RPW], indicating good preservation of renal function and remission of hydronephrosis. For 26 patients with double J stents before operation, significant reduction of USSQ average score (100.4±6.6 vs. 82.1±4.9, P < 0.01) evidenced better life quality preserving ability of coated metal stent versus double J stent. CONCLUSION: Coated metal stent implantation is a safe and minimally invasive management of ureteral stricture providing a satisfying long-term patency rate, after which the patients' quality of life and renal function could be both improved. This method could serve as a promising alternative long-term maintenance treatment option for patients with URL-US, especially when traditional endoscopic interventions failed.

Urolithiasis is a global phenomenon. Cystolithiasis is common in parts of Africa due to low protein intake and dehydration from endemic diarrhoeal illnesses. Nephrolithiasis is less prevalent than in high-income countries, probably due to a variety of lifestyle issues, such as a more elemental diet, higher physical activity, and less obesity. Although renal stones are less common in low- and middle-income countries (LMICs), the social and economic impacts of nephrolithiasis are still considerable; many stones present late or with complications such as upper urinary tract obstruction or urosepsis. These may lead to the development of chronic kidney disease, or end-stage renal failure in a small proportion of cases, conditions for which there is very poor provision in most LMICs. Early treatment of nephrolithiasis by the least invasive method possible can, however, reduce the functional consequences of urinary stone disease. Although extracorporeal lithotripsy is uncommon, and endoscopic interventions for stone are not widespread in most of Africa, percutaneous nephrolithotomy and ureteroscopic renal surgery are viable techniques in those regional centres with infrastructure to support them. Longitudinal mentoring has been shown to be a key step in the adoption of these minimally invasive procedures by local surgeons, something that has been difficult during the coronavirus disease 2019 (COVID-19) pandemic due to travel restriction. Augmented reality (AR) technology is an alternative means of providing remote mentoring, something that has been trialled by Urolink, the MediTech Trust and other global non-governmental organisations during this period. Our preliminary experience suggests that this is a viable technique for promulgating skills in LMICs where appropriate connectivity exists to support remote communication. AR may also have long-term promise for decreasing the reliance upon short-term surgical visits to consolidate competence, thereby reducing the carbon footprint of global surgical education.

BACKGROUND: To compare ureteroscopy (URS) complementary treatment following extracorporeal shock wave lithotripsy (SWL) failure with primary URS lithotripsy for proximal ureteral stones > 10 mm, and try to find out acceptable number of SWL sessions followed by safe URS. METHODS: This was a retrospective study following approval from Medical Ethics Committee of People's Hospital of Chongqing Banan District. Patients (n = 340) who received URS in our hospital for stones > 10 mm from Jan 2015 to June 2020 were divided into two groups according to their previous SWL history. Group 1 consisted of 160 patients that underwent unsuccessful SWL before URS. Group 2 encompassed 180 patients without SWL before URS. Patient's operative outcomes were compared. A logistic regression and receiver operator characteristics (ROC) were used to identify the acceptable number of SWL sessions prior to URS, regarding the intra-operative complications of URS. RESULTS: The group 1 required more surgery time (41.38 ± 11.39 min vs. 36.43 ± 13.36 min, p = 0.01). At the same time, more intra-operative (68.1% VS 22.8%, p < 0.05) and post-operative (35% VS 18.0%, p = 0.001) complications occurred in group 1. Need more hospital stay in group 1 (2.7 ± 1.2 days vs 1.6 ± 1.1 days, p < 0.05). More patients in group 1 need further URS (16.3% VS 8.9%, p = 0.029). After second URS, the SFR of URS in two groups was insignificant differences (82.5% VS 88.9%, p > 0.05). The median (25-75%) of SWL sessions before URS was 2 (1-3) in group 1. According to the results of logistic regression analysis, patients suffered more SWL failure have an increased risk of complications during URS (OR = 1.995, 95% CI: 1.636-2.434). ROC showed that the optimal number of SWL session followed by URS were 0.5, with a sensitivity of 67.7% and specificity of 71.5%. Intra-operative complication rates of URS treatment were higher in patients who suffered > 1 SWL failure (72.6% vs 57.4%, p = 0.047). CONCLUSION: There was no acceptable number of SWL sessions that could be followed by URS with fewer intra-operative complications. Patients who underwent previous SWL were likely to suffer more intra-operative complications, the average operating time, hospitalization time, and needing further treatment, during URS treatment for proximal ureteral stones larger than 10 mm.

There is very little published literature on urologic diseases prior to 1947 from areas now constituting Pakistan. From inception of the country to 1970s, urology was part of surgery practiced by general surgeons except for two urology units established in 1960s. The real take off of urology began with introduction of transurethral resection of prostate (TURP) in 1980s, ushering the era of endourology; the second era of which began with ureteroscopy along with extracorporeal shockwave lithotripsy (ESWL) in 1987-1989, percutaneous nephrolithotomy in 1992 and introduction of percutaneous nephrostomy in 1997. Renal transplantation was started in 1979 from living-related donors and currently, there are 19 renal transplant centres. At present, there are 11 specialized kidney centers in the country. Urology has undergone marked metamorphosis during the new millennium. It has given rise to many sub-specialties. Over the past few decades, the classical surgical training has shifted towards adaptation of surgical simulation labs. We foresee more specialized urology centers and strengthening of sub-specialty practices in the country.

OBJECTIVE: To observe the preventive effect of medicated plaster at Dazhui (GV 14) on preventing perioperative hypothermia in patients undergoing plasmakinetic resection of prostate (PKRP) and ureteroscopic laser lithotripsy. METHODS: A total of 300 patients with ASA gradeâ orâ ¡receiving ureteroscopic laser lithotripsy or PKRP under total intravenous anesthesia (TIVA) were randomly divided into an observation group and a control group, 150 cases in each group. The patients in the control group received routine heat preservation measures, while on the basis of the control group, the patients in the observation group were treated with medicated plaster at Dazhui (GV 14) 30 min before operation. The temperature (ear temperature), mean arterial pressure (MAP), heart rate and blood oxygen saturation (SpO2) at each time point (resting state before operation, 5, 10 min into operation, at the end of operation, 5 and 10 min after operation) were recorded; the number of hypothermia, the classification of postoperative shivering degree, operation time, propofol dosage, intraoperative infusion volume and intraoperative flushing fluid volume were recorded. RESULTS: The temperature at 5 and 10 min into operation as well as at the end of operation in the two groups was all lower than that before operation and at previous time point (P<0.01). The temperature at 5 and 10 min after operation in the two groups was all higher than that at previous time point (P<0.01), but still lower than that before operation (P<0.01). The temperature at 10 min into operation, at the end of operation, 5 and 10 min after operation in the observation group was higher than that in the control group (P<0.01, P<0.05). The total incidence rate of hypothermia in the observation group was 2.0% (3/150), which was significantly lower than 13.3% (20/150) in the control group (P<0.01). The total incidence rate of shivering was 18.0% (27/150) in the observation group and 28.7% (43/150) in the control group (P>0.05). CONCLUSION: The medicated plaster at Dazhui (GV 14) can effectively prevent perioperative hypothermia and improve comfort in patients undergoing PKRP and ureteroscopic laser lithotripsy.

OBJECTIVE: To verify the efficacy of transcutaneous electrical acupoint stimulation (TEAS) on catheter related bladder discomfort after ureteroscopic lithotripsy. METHODS: Sixty male patients with selective ureteroscopic lithotripsy under general anesthesia were randomly divided into a TEAS group (30 cases, one case dropped off) and a sham TEAS group (30 cases, 2 cases dropped off). Before anesthesia induction, the patients in the TEAS group were treated with TEAS at Guanyuan (CV 4), Zhongji (CV 3), Zusanli (ST 36) and Sanyinjiao (SP 6) for 30 min, with disperse-dense wave, frequency of 2 Hz/ 15 Hz and current intensity of 6 to 10 mA. The patients in the sham TEAS group were treated with the same TEAS device at the same acupoints, but no electrical stimulation was given. After 30 min, anesthesia induction started. The total dosages of propofol and remifentanil in the two groups were recorded, and the time of operation and anesthesia, the time of wake-up and the time of stay in postanesthesia care unit (PACU) were recorded. The postoperative recovery was evaluated 5 min (T1) after wake-up, 1 h (T2), 2 h (T3) and 6 h (T4) after the operation, including the severity of urinary tract irritation and visual analogue scale (VAS) score. The occurrence of adverse reactions was observed, such as nausea and vomiting, dizziness and headache. RESULTS: The dosage of remifentanil in the TEAS group was significantly lower than that in the sham TEAS group (P<0.05); but the dosage of propofol had no significant difference between the two groups (P>0.05). Compared with the sham TEAS group, the incidence of more-than-moderate urinary tract irritation symptoms in the TEAS group was reduced (P<0.05), and the VAS scores 1 and 2 h after operation were reduced (P<0.05). CONCLUSION: The 30-min TEAS at Guanyuan (CV 4), Zhongji (CV 3), Zusanli (ST 36) and Sanyinjiao (SP 6) before anesthesia induction could significantly control the severity of postoperative urinary tract irritation in patients with ureteroscopic lithotripsy, reduce the dosage of anesthetic drugs and relieve postoperative pain.

PURPOSE OF REVIEW: Routine ureteroscopy (URS) for stone disease is performed under a general anaesthesia. However, controversy exists on the role of loco-regional anaesthesia and the outcomes associated with it. Here we review the challenges, outcomes and complications of loco-regional anaesthesia for URS. A Cochrane style review was performed in accordance with the preferred reporting items for systematic reviews and meta-analyses guidelines to evaluate the outcomes of loco-reginal anaesthesia for URS in stone disease, including all English language articles from January 1980 and December 2019. RECENT FINDINGS: Twenty-one studies (1843 procedures) with a mean age of 46 years and a maleâ:âfemale ratio of 1.2â:â1 underwent URS under loco-regional anaesthesia. The mean stone size was 9âmm (range:4-21âmm) and except five papers, all other papers included stones in the ureter of which the majority were in the distal ureter. The conversion to general anaesthesia was needed in 2.7% patients (range 1-21%) across studies, with a stone free rate of 48-100%. The complication rate varied from 1.4 to 36%. Although the intraoperative complications included ureteric injury (nâ=â21) or perforation (nâ=â4), the postoperative complications included fever (nâ=â37), urinary tract infection (nâ=â20), haematuria (nâ=â4), urosepsis (nâ=â4) and others (nâ=â7). SUMMARY: The present systematic review shows that local anaesthetic URS is a potential alternative to general anaesthetic URS in carefully selected patients. Randomised controlled trials with subgroup analysis are required to further assess whether loco-regional anaesthesia URS is noninferior to general anaesthesia URS and might help determine if the former approach should become more widespread.

Rationale: Dietary exposure to aristolochic acids and similar compounds (collectively, AA) is a significant risk factor for nephropathy and subsequent upper tract urothelial carcinoma (UTUC). East Asian populations, who have a high prevalence of UTUC, have an unusual genome-wide AA-induced mutational pattern (COSMIC signature 22). Integrating mutational signature analysis with clinicopathological information may demonstrate great potential for risk ranking this UTUC subtype. Methods: We performed whole-genome sequencing (WGS) on 90 UTUC Chinese patients to extract mutational signatures. Genome sequencing data for urinary cell-free DNA from 26 UTUC patients were utilized to noninvasively identify the mutational signatures. Genome sequencing for primary tumors on 8 out of 26 patients was also performed. Metastasis-free survival (MFS) and cancer-specific survival (CSS) were measured using Kaplan-Meier methods. Results: Data analysis showed that a substantial proportion of patients harbored the AA mutational signature and were associated with AA-containing herbal drug intake, female gender, poor renal function, and multifocality. Field cancerization was found to partially contribute to multifocality. Nevertheless, AA Sig subtype UTUC patients exhibited favorable outcomes of CSS and MFS compared to the No-AA Sig subtype. Additionally, AA Sig subtype patients showed a higher tumor mutation burden, higher numbers of predicted neoantigens, and infiltrating lymphocytes, suggesting the potential for immunotherapy. We also confirmed the AA signature in AA-treated human renal tubular HK-2 cells. Notably, the AA subtype could be ascertained using a clinically applicable sequencing strategy (low coverage) in both primary tumors and urinary cell-free DNA as a basis for therapy selection. Conclusion: The AA mutational signature as a screening tool defines low-risk UTUC with therapeutic relevance. The AA mutational signature, as a molecular prognostic marker using either ureteroscopy and/or urinary cell-free DNA, is especially useful for diagnostic uncertainty when kidney-sparing treatment and/or immune checkpoint inhibitor therapy were considered.

INTRODUCTION: We aimed to evaluate the predictive factors in a holistic manner for ureterorenoscopy (URS) outcomes in proximal ureteral stones by a multicenter study. MATERIALS AND METHODS: The data of patients who underwent URS for proximal ureteral stones between the years 2015 and 2018 in eight centers were recorded retrospectively. Patients were divided into two groups according to URS success: Group 1 consisted of patients with successful URS, and Group 2 consisted of patients with unsuccessful URS. The two groups were compared in terms of risk factors, stone, and clinical characteristics of patients. RESULTS: A total of 638 patients were included in the study. Group 1 consisted of 527 (82.6%) patients, and Group 2 consisted of 111 (17.4%) patients. In multivariate logistic analysis, the key risk factors for URS success was found to be age (OR = 0.980, 95% [CI] = 0.963-0.996, p = 0.018), stone area (OR = 0.993, 95% [CI] = 0.989-0.997, p = 0.002), and operation time (OR = 0.981, 95% [CI] = 0.968-0.994, p = 0.005). CONCLUSIONS: To make the treatment decision of proximal ureteral stones, it is necessary to examine several parameters including available equipment, stone, and patient characteristics. Physicians should keep these risk factors in mind in the decision of treatment options.

BACKGROUND: The drug Canephron N is a combination of extracts of centaury, lovage and rosemary. Moderate antispasmoic, anti-inflammatory, antioxidant, diuretic and antimicrobial effects are of great interest for urological practice. The optimal combination of components that were made of herbal medicine allows to use their synergistic effect for prevention of recurrence of urinary stone disease. The experience of using the drug Canephron in clinical practice is of great interest. AIM: to clarify the clinical efficiency of Canephron N in patients with urinary stone disease after surgical treatment and to evaluate the changes in diuresis and calcium excretion. MATERIALS AND METHODS: The results of using the drug Canephron after surgical treatment of urinary stone disease are provided. The changes in diuresis and calcium excretion in 75 patients undergone surgical treatment of urinary stone disease were studied. Patients after ureteroscopy, percutaneous nephrolithotomy and extracorporeal shock-wave lithotripsy were prescribed treatment to prevent stone formation including herbal drug Canephron N. RESULTS: At baseline, there was negative correlation between 24-hours diuresis and calcium excretion in all groups. During follow-up, a positive correlation between 24-hours diuresis and calcium excretion was found in patients receiving Canephron N and other types of treatment. The average follow-up was 390 days. During this period, recurrence was noted in 1 patient receiving Canephron, 4 patients in patients who took other drugs and in 5 patients who didnt receive any treatment. CONCLUSION: Risk factors of stone formation persist after surgical treatment of urinary stone disease. This is reflected in a negative correlation between 24-hour diuresis and calcium excretion. During treatment, a positive correlation between diuresis and calcium excretion was noted in patients with urinary stone disease. The use of drugs that affect stone formation as well as herbal medicine Canephron N allow to obtain comparable ratio of diuresis and calcium excretion.

OBJECTIVE: To evaluate the incidence, clinical presentation and factors associated with the development of urinary sepsis after performing ureterorenoscopy. MATERIAL AND METHODS: Retrospective study of patients undergoing ureterorenoscopy for the treatment of lithiasis between July 2015 and October 2017. Patients who developed urinary sepsis during the 30 days following the intervention were identified. Personal, clinical, surgical and microbiological backgrounds were collected. Statistical analysis was performed with the Chi squared test (or Fisher's exact test), Student's t (or U Mann-Whitney) or logistic regression as appropriate. RESULTS: 246 ureterorenoscopies were performed, 184 (74.8%) on ureteral stones and 62 (25.2%) on kidney stones, with a mean age of 52 (44.5-59.5) years. After procedure, 18 (7.3%) patients developed urinary sepsis, 10 of them (55.5%) occurred in the first 24h. The urine culture showed enterobacteria (61.1%) and enterococci (38.9%). The antibiogram showed greater sensitivity to nitrofurantoins (100%) and quinolones (72%). The statistical analysis showed that female sex, the clinical debut of urolithiasis as urinary sepsis, having received antibiotic or having required urinary diversion by a double J during debut, positive presurgical uroculture and the persistence of residual lithiasis after surgery were significantly associated (P<.05) with the development of urinary sepsis after ureterorenoscopy. CONCLUSION: Urinary sepsis is a complication that appears after performing ureterorenoscopy, especially in female patients with a history of urinary sepsis, antibiotic therapy, double J, previous positive urine culture or residual lithiasis after the procedure.

Introduction: Patients unfit for general anesthesia who present with renal tract pathology currently have limited options. Many of these patients present in the emergency setting with imperative reasons for intervention, including sepsis, renal failure, and pain. Conservative management and temporizing measures, such as percutaneous nephrostomy, are associated with significant morbidity. Ureterorenoscopy (URS) is a central component of the management of upper tract disease and is routinely performed under general anesthesia. We describe our institution's experience of URS using only local anesthetic (LA) lubricating gel per urethra. Methods: A single centre, retrospective analysis of 78 patients was performed for an 11 year period. Demographic data and Charlson comorbidity index scoring were collected for all patients. Outcomes, including stone-free rates, tolerability, and complications, were analyzed. Results: In total 58% of patients were men. Mean age was 68 and Charlson comorbidity index was 5.2. Indications for URS included pain (68%) and renal failure (15%). Totally 10% of patients previously had retrograde stenting because of sepsis. Median stone size was 8 mm. All patients were able to tolerate the procedure and none were abandoned because of pain. The overall stone-free rate was 82% after one procedure. The stone-free rate for mid and distal ureteral stones was 97%. Nineteen percent of patients were left with a ureteral stent after the procedure, with the remaining patients left totally tubeless. Median length of stay was 1 day. There were no complications above Clavien Grade 2. Conclusion: Urologists are increasingly faced with unfit patients presenting with urolithiasis. In the appropriately selected patient, LA flexible ureterorenoscopy is a feasible option with good outcomes. This approach is a useful addition to the armamentarium available to patients deemed unsuitable for general or regional anesthesia.

PURPOSE: Postoperative ureteroscopy patients can develop bladder spasms, complaints of pain, and the urgent need to void during emergence from anesthesia. Discomfort leads to patient agitation, resulting in a risk to patient safety. The purpose of this study was to determine the effectiveness of a preemptive preoperative belladonna and opium (B + O) suppository on postoperative bladder comfort, narcotic requirements, and length of stay of ureteroscopy patients. DESIGN: A prospective double-blind study was conducted. METHODS: Fifty adult outpatients scheduled for ureteroscopy were assigned to routine care or a B + O suppository immediately after anesthesia induction. Urinary urgency and pain were assessed every 15 minutes. FINDINGS: Urgency significantly decreased in the B+O group, with less than half reporting urgency at discharge. CONCLUSIONS: Pre-emptive preoperative administration of a B + O suppository before ureteroscopy results in decreased urinary urgency during the postoperative recovery. Pre-emptive preoperative interventions can result in positive outcomes before discharge.

BACKGROUND: The European School of Urology (ESU) started the European Urology Residents Education Programme (EUREP) in 2003 for final year urology residents, with hands-on training (HOT) added later in 2007. OBJECTIVE: To assess the geographical reach of EUREP, trainee demographics, and individual quality feedback in relation to annual methodology improvements in HOT. DESIGN, SETTING, AND PARTICIPANTS: From September 2014 to October 2017 (four EUREP courses) several new features have been applied to the HOT format of the EUREP course: 1:1 training sessions (2015), fixed 60-min time slots (2016), and standardised teaching methodology (2017). The resulting EUREP HOT format was verified by collecting and prospectively analysing the following data: total number of participants attending different HOT courses; participants' age; country of origin; and feedback obtained annually. RESULTS AND LIMITATIONS: A total of 796 participants from 54 countries participated in 1450 HOT sessions over the last 4 yr. This included 294 (20%) ureteroscopy (URS) sessions, 237 (16.5%) transurethral resection (TUR) sessions, 840 (58%) basic laparoscopic sessions, and 79 (5.5%) intermediate laparoscopic sessions. While 712 residents (89%) were from Europe, 84 (11%) were from non-European nations. Of the European residents, most came from Italy (16%), Germany (15%), Spain (15%), and Romania (8%). Feedback for the basic laparoscopic session showed a constant improvement in scores over the last 4 yr, with the highest scores achieved last year. This included feedback on improvements in tutor rating (p=0.017), organisation (p<0.001), and personal experience with EUREP (p<0.001). Limitations lie in the difficulties associated with the use of an advanced training curriculum with wet laboratory or cadaveric courses in this format, although these could be performed in other training centres in conjunction with EUREP. CONCLUSIONS: The EUREP trainee demographics show that the purpose of the course is being achieved, with excellent feedback reported. While European trainees dominate the demographics, participation from a number of non-European countries suggests continued ESU collaboration with other national societies and wider dissemination of simulation training worldwide. PATIENT SUMMARY: In this paper we look at methodological improvements and feedback for the European Urology Residents Education Programme hands-on-training over the last 4 yr.

Transcutaneous electrical acupoint stimulation (TEAS) is an effective analgesic measure. We studied the analgesic effect of TEAS by applying it alone after ureteroscopic lithotripsy, rather than applying it as a supplementary analgesic measure. Participants (n = 120) scheduled to undergo ureteroscopic holmium laser lithotripsy, were enrolled and randomly assigned into Group T (TEAS n = 60) and Group C (Control, n = 60). The participants in Group T were treated with TEAS for postoperative analgesia. TEAS were implemented on bilateral Shenyu (BL23) and Yinlingquan (SP9) at the time backward and the time at 4, 8, 12 h postoperatively. TEAS was re-implemented three times on the target acupoints for the next 2 days. When TEAS failed to meet the analgesic effect, the participants were given tramadol hydrochloride tablets of 100 mg. Participants of Group C were given tramadol hydrochloride tablets for postoperative analgesia. The primary outcome of VAS scores at the time backward (T0), 4 h (T1), 12 h (T2), 24 h (T3), 48 h (T4) postoperatively and the amount of remedy for analgesic consumption within 48 h postoperatively were compared. The secondary outcome of adverse reactions and plasma concentrations of serotonin (5-HT) and substance P (SP) at T0, T1, T2, T3, T4 were detected, respectively. The VAS scores at T1, T2, T3, T4 postoperatively in two groups were lower than T0. Compared to group C, the VAS scores at T1 (3.68 ± 0.68 vs. 4.79 ± 0.82, P = 0.01), T2 (2.64 ± 0.72 vs. 3.92 ± 0.88, P = 0.03), T3 (2.21 ± 0.88 vs. 3.38 ± 0.74, P < 0.01) in Group T were lower, and total remedy of analgesic consumption was significantly lower (127.14 ± 28.46 vs. 415.27 ± 86.37, P < 0.01) within 48 h postoperatively. The plasma concentrations of 5-HT in Group T was lower than Group C at T1 (348.54 ± 138.49 vs. 418.69 ± 124.68, P = 0.03), T2 (324.28 ± 112.73 vs. 398.52 ± 114.53, P < 0.01), T4 (309.64 ± 129.09 vs. 388.46 ± 115.36, P = 0.04) postoperatively and concentrations of SP at T1 (59.38 ± 24.68 vs. 78.93 ± 26.32, P < 0.01), T2 (49.36 ± 25.55 vs. 66.49 ± 23.57, P = 0.02), T3 (42.19 ± 24.36 vs. 64.15 ± 28.16, P = 0.04), T4 (39.26 ± 19.88 vs. 54.64 ± 20.62, P = 0.02) postoperatively were also lower than Group C. Meanwhile, the occurrences of vertigo (6.7 vs. 18.3%, P < 0.01), nausea and vomiting (11.7 vs. 21.7%, P < 0.01), constipation (10.0 vs. 20.0%, P = 0.03) in Group T were also lower. Application of TEAS alone was associated with effective alleviation of postoperative pain, reduction of postoperative analgesics consumption, decrease of plasma concentration of algogenic substance and the incidence of adverse reactions after ureteroscopic lithotripsy.

Urothelial carcinoma in the upper tract is rare and often discussed separately. Many established risk factors were identified for the disease, including genetic and external risk factors. Radiographic survey, endoscopic examination and urine cytology remained the most important diagnostic modalities. In localized upper tract urothelial carcinomas, radical nephroureterectomy with bladder cuff excision are the gold standard for large, high-grade and suspected invasive tumors of the renal pelvis and proximal ureter, whereas kidney-sparing surgeries should be considered in patients with low-risk disease. Advances in technology have given endoscopic surgery an important role, not only in diagnosis, but also in treatment. Although platinum-based combination chemotherapy is efficacious in advanced or metastatic disease, current established chemotherapy regimens are toxic and lack a sustained response. Immune checkpoint inhibitors have led to a new era of treatment for advanced or metastatic urothelial carcinomas. The remarkable results achieved thus far show that immunotherapy will likely be the future treatment paradigm. The combination of immune checkpoint inhibitors and other agents is another inspiring avenue to explore that could benefit even more patients. With respect to the high incidence rate and different clinical appearance of upper tract urothelial carcinomas in Taiwan, a possible correlation exists between exposure to certain external risk factors, such as arsenic in drinking water and aristolochic acid in Chinese herbal medicine. As more gene sequencing differences between upper tract urothelial carcinomas and various disease causes are detailed, this has warranted the era of individualized screening and treatment for the disease.
