Influence of tract location on the outcomes of endoscopic combined intrarenal surgery: A retrospective analysis of 1000 cases.

OBJECTIVES: This study aimed to investigate the influence of tract location on surgical outcomes in endoscopic combined intrarenal surgery (ECIRS), considering the location of residual stones. METHODS: From January 2015 to December 2021, 1417 consecutive patients underwent ECIRS in three hospitals. After excluding patients with preoperative percutaneous nephrostomy, intended multi-stage procedures, those with a tract in the renal pelvis, and those with multiple tracts, 1000 patients were retrospectively analysed by comparing three groups based on tract location: group 1 (upper calyx), group 2 (middle calyx), and group 3 (lower calyx). A multivariate logistic regression model was implemented to assess whether the tract location independently affected the stone-free status. RESULTS: Patient characteristics were significantly different among the groups in terms of age, stone laterality, presence of calyceal stones, and hydronephrosis. There were no differences in stone-free rate (SFR) among the three groups. Multivariate analysis indicated that the tract location (group 1 or 2 compared with group 3) did not significantly affect the stone-free status (odds ratio = 1.4, 0.9-1.9, p = 0.066). Surgical duration significantly varied among the groups, with the shortest time observed in group 1. Organ injury was observed exclusively in group 1 (1.13%). Residual fragments were predominantly found in the lower calyx, with the calyx associated with the tract being the second most common location. CONCLUSIONS: Tract location does not significantly affect SFR. To improve the SFR, observation of the lower calyx and tract placement is important.

Shedding light on polypragmasy of pain after transurethral prostate surgery procedures: a systematic review and meta-analysis.

PURPOSE AND OBJECTIVE: To evaluate and compare the incidences of post-operative pelvic pain (PPP) in patients undergoing ablation, enucleation and conventional transurethral resection of the prostate (TURP). METHODS: A systematic review and meta-analysis was conducted according to the PRISMA guidelines. Using MEDLINE via PubMed and Cochrane CENTRAL, randomised control trials (RCTs) and observational studies reporting PPP rates post-ablation, enucleation or TURP were identified. The risk of biases (RoB) in RCTs and observation studies were assessed using the Cochrane RoB1.0 tool and the Newcastle-Ottawa Scale, respectively. RESULTS: 62 studies were included for qualitative analysis, while 51 of them reported number of patients with PPP post-intervention. Three observational studies and 13 RCTs compared the rates of PPP in patients undergoing ablation, enucleation or TURP. The most reported types of PPP are dysuria, abdominal pain and irritative symptoms. The pooled incidence of PPP at 1-month follow-up in patients undergoing ablation, enucleation and TURP were 0.15 (95% CI 0.10-0.22), 0.09 (95% CI 0.04-0.19 and 0.10 (95% CI 0.06-0.15), respectively. PPP is no longer prevalent at 3-months and onwards post-operatively. Ablation is associated with a higher risk of PPP than enucleation (RR 2.19, 95% CI 1.04-4.62) and TURP (RR 2.40, 95% CI 1.03-5.62) in observational studies but not RCTs; and there were no significant differences in the rates of PPP upon comparison of other modalities. CONCLUSION: PPP is common after transurethral benign prostatic hyperplasia surgery. Patients undergoing ablation had a higher rate of post-intervention PPP than those undergoing enucleation and TURP in observational studies.

Listening to Music during Outpatient Cystoscopy Reduces Pain and Anxiety and Increases Satisfaction: Results from a Prospective Randomized Study.

BACKGROUND: This study investigates the effect of classical music, music of patients' own choice, or no music on pain reduction during elective cystoscopy. OBJECTIVES: The aim of the study was to describe the effect of listening to classical music, music of patients' own choice, or no music on patient's pain and satisfaction rates when carrying out an elective cystoscopy and the effect on the assessment capability of the performing urologist. DESIGN, SETTING, AND PARTICIPANTS: This randomized trial included 127 patients undergoing elective cystoscopy at the Urological Department of the University Clinic of Munich between June 2019 and March 2020. Outcome Measurements and Statistical Analysis: Patients were assigned randomly to 3 groups: group I: listening to standardized classical music (n = 35), group II: listening to music according to the patients' choice (n = 34), and control group III: no music (n = 44). Prior to cystoscopy, anxiety levels were assessed by the Beck Anxiety Inventory (BAI). The Visual Analog Scale (VAS, range 1-100) was used for a self-assessment of pain, discomfort, and satisfaction. Statistical analysis was done with Spearman's rank correlation and t-tests. RESULTS AND LIMITATIONS: The median age was 63 (range 27-91) years. The duration of cystoscopy was 5.7 (1-30) min. Patients had undergone a median of 2.3 cystoscopies in the past. Between giving informed consent and cystoscopy, patients had to wait for a median of 64 (0-260) min. The median VAS pain score was significantly lower in group I at 1.7 and group II at 2.3 versus 5.2 in the control group III (p < 0.001). The control group III had significantly worse pain and patient satisfaction rates compared with groups I and II. Group I had a significant lower VAS pain score than groups II and III (p < 0.001). Classical music also increased the assessment capability of the preforming urologist. CONCLUSIONS: Listening to music during elective cystoscopy significantly reduces pain and distress and leads to higher patient and surgeon satisfaction. We recommend listening to classical music or music chosen by the patients during outpatient flexible/rigid cystoscopy in daily clinical routine. Patient Summary: In this study, we found that patients who listened to classical music or music of their own choice while undergoing a cystoscopy showed significant reduction of pain and distress.

Complications and Interventions in Patients with an Artificial Urinary Sphincter: Long-Term Results.

PURPOSE: The artificial urinary sphincter is a common treatment of male urinary incontinence. We sought to characterize long-term rates of artificial urinary sphincter revision/removal and reimplantation, and associated risk factors. MATERIALS AND METHODS: We performed a population based, retrospective study using the Ontario Health Insurance Plan database of all male patients who underwent artificial urinary sphincter implantation from 1994 to 2013. Hospital, diagnostic and billing codes were used to identify patients. The Kaplan-Meier method and multivariable Cox proportional hazards models were applied to examine the cumulative incidence of artificial urinary sphincter reimplantation and revision/removal, and identify risk factors, respectively. RESULTS: A total of 1,632 male patients underwent initial implantation of an artificial urinary sphincter. The 10-year revision/removal and reimplantation rates were 34% and 27%, respectively. There was no difference between high and low volume hospitals or between community and academic hospitals in terms of revision/removal. A high level of comorbidity was associated with an increasing risk of removal/revision. The reimplantation rate was significantly lower in patients who underwent insertion at hospitals with the highest volume of surgery (HR 0.55, 95% CI 0.37-0.82, p <0.01). A high level of comorbidity was not associated with an increasing risk of reimplantation. Preimplantation radiotherapy was not significantly associated with the risk of reimplantation (p = 0.17) or revision/removal (p = 0.95). Other factors were not significantly associated with reimplantation or revision/removal. CONCLUSIONS: Most men who undergo artificial urinary sphincter placement still have a device without repeat surgery 10 years following insertion. Radiotherapy does not increase the risk of repeat surgery. A high level of comorbidity was associated with an increasing risk of removal/revision.

Quantifying Nonindex Hospital Readmissions and Care Fragmentation after Major Urological Oncology Surgeries in a Nationally Representative Sample.

PURPOSE: We quantified the underestimation of hospital readmission rates that can occur with institutional databases and the incidence of care fragmentation among patients undergoing urological oncology procedures in a nationally representative database. MATERIALS AND METHODS: The 2013 Nationwide Readmissions Database was queried for patients undergoing prostatectomy, cystectomy, nephroureterectomy, nephrectomy, partial nephrectomy and retroperitoneal lymph node dissection for urological malignancies. Nationally representative 30 and 90-day readmission and care fragmentation rates were calculated for all procedures. Readmission rates with and without nonindex hospital readmissions were compared with Pearson's chi-square test. Multivariable logistic regression models were used to identify predictors of care fragmentation at 90-day followup. RESULTS: For all surgical procedures readmission rates were consistently underestimated by 17% to 29% at 90-day followup. The rates of care fragmentation among readmitted patients were similar for all procedures, ranging from 24% to 34% at 90-day followup. Overall 1 in 4 readmitted patients would not be captured in institutional databases and 1 in 3 readmitted patients experienced care fragmentation. Multivariable models did not identify a predictor of care fragmentation that was consistent across all procedures. CONCLUSIONS: The high rate of underestimation of readmission rates across all urological oncology procedures highlights the importance of linking institutional and payer claims databases to provide more accurate estimates of perioperative outcomes and health care utilization. The high rate of care fragmentation across all procedures emphasizes the need for future efforts to understand the clinical relevance of care fragmentation in patients with urological malignancies, and to identify patients at risk along with potentially modifiable risk factors for care fragmentation.

Rates and Risk Factors for Opioid Dependence and Overdose after Urological Surgery.

PURPOSE: Effective pain management is a critical component of the perioperative process with opioids representing a mainstay of therapy. The opioid epidemic is a growing concern in the United States. The goal of this study was to quantify the risk of opioid dependence or overdose among patients undergoing urological surgery and to identify risk factors of opioid dependence or overdose. MATERIALS AND METHODS: We retrospectively reviewed data on urological surgery from 2007 to 2011. Data sources included the HCUP (Healthcare Cost and Utilization Project) inpatient, ambulatory surgery and emergency department data sets. Outcomes of postoperative opioid dependence and overdose were identified by previously validated ICD-9 codes. Multivariable logistic regression adjusted for surgical procedure was performed to identify predictors of opioid dependence or overdose following urological surgery. RESULTS: Overall 675,527 patients underwent urological surgery, of whom 0.09% were diagnosed with opioid dependence or overdose. Patients in whom opioid dependence or overdose developed were younger (median age 51 vs 62 years), carried nonprivate insurance (69.6% vs 66%), underwent an inpatient procedure (81.0% vs 42.4%) and had a longer length of stay (median 3 vs 0 days) and a history of depression (14.4% vs 3.4%) or chronic obstructive pulmonary disease (20.3% vs 8.9%, all p <0.001). On adjusted multivariable analysis these factors remained independent risk factors for opioid dependence or overdose. CONCLUSIONS: Postoperative opioid dependence or overdose affects 1 of 1,111 urological surgery patients. Risk factors for opioid dependence or overdose included younger age, inpatient surgery and increasing hospitalization duration, baseline depression, tobacco use and chronic obstructive pulmonary disease as well as insurance provider, including Medicaid, Medicare (age less than 65 years) and noninsured status.

Case distribution and complications of mid-urethral sling surgery in a Canadian city before and after the Health Canada advisory on pelvic floor mesh.

INTRODUCTION AND HYPOTHESIS: Increased incidences of complications related to the use of mid-urethral slings (MUS) for the treatment of stress urinary incontinence resulted in both the Food and Drug Administration (FDA) and Health Canada issuing advisories in 2008 and 2010 respectively. The purpose of this study was to assess the effect these advisories had on the number of surgeons performing MUS surgery and post-surgical complications in Calgary, Canada. METHODS: In this study, we conducted a retrospective analysis of administrative data between 2006 and 2011. Post-surgical complications were identified using diagnostic codes. All rates were adjusted for the increase in the female population in Calgary during the study period. An interrupted time series model was used to evaluate any changes in the number of surgeons performing MUS surgery and any post-surgical changes from the period before and that after the advisories. RESULTS: The number of surgeons performing MUS surgery and the number of surgeries performed decreased over the study period, although neither of these was significantly related to the advisories. In terms of complications, we did not observe a significant change in the rate of repeat MUS surgeries, inpatient admissions, emergency department visits, or ambulatory care visits within 2 years of initial surgery. CONCLUSION: The FDA and Health Canada advisories had no effect on the use of MUS in Calgary. This suggests either that they bear little influence on local surgeons' practices, or that safety was already at such a high level that improvements were not possible.

Influence of variations in arterial PCO2 on surgical conditions during laparoscopic retroperitoneal surgery.

BACKGROUND: Although deep neuromuscular block (post-tetanic-count 1-2 twitches) improves surgical conditions during laparoscopic retroperitoneal surgery compared with standard block (train-of-four 1-2 twitches), the quality of surgical conditions varies widely, often related to diaphragmatic contractions. Hypocapnia may improve surgical conditions. Therefore we studied the effect of changes in arterial carbon dioxide concentrations on surgical conditions in patients undergoing laparoscopic surgery under general anaesthesia and deep neuromuscular block. METHODS: Forty patients undergoing elective laparoscopic surgery for prostatectomy or nephrectomy received propofol/remifentanil anaesthesia and deep neuromuscular block with rocuronium. Patients were randomized to surgery under hypocapnic or hypercapnic conditions. During surgery, the surgical conditions were evaluated using the 5-point Leiden-Surgical Rating Scale (L-SRS) ranging from 1 (extremely poor conditions) to 5 (optimal conditions) by the surgeon, who was blinded to group. RESULTS: Mean (sd) arterial carbon dioxide concentrations were 4.5 (0.6) [range: 3.8-5.6] kPa under hypocapnic and 6.9 (0.6) [6.1-8.1] kPa under hypercapnic conditions. The L-SRS did not differ between groups: 4.84 (0.4) [4-5] in hypocapnia and 4.77 (0.4) [3.9-5] in hypercapnia. Ninety-nine percent of ratings were good or excellent irrespective of treatment. CONCLUSIONS: Deep neuromuscular block provides good to optimal surgical conditions in laparoscopic retroperitoneal urological surgery, independent of the level of arterial [Formula: see text]. CLINICAL TRIAL REGISTRATION: NCT01968447.

Effects of preoperative dutasteride treatment in holmium laser enucleation of the prostate.

OBJECTIVES: To investigate factors influencing the degree of difficulty in finding and maintaining an appropriate plane on the surgical capsule of the prostate during holmium laser enucleation of the prostate. METHODS: A total of 116 men undergoing holmium laser enucleation of the prostate for benign prostate hyperplasia between January 2010 and September 2013 at our hospital were included in this analysis. The degree of difficulty in finding and maintaining the plane of the surgical capsule of the prostate was retrospectively evaluated and graded by using video-based analysis according to newly defined criteria (grade I, least difficult; grade IV, most difficult). Factors influencing the degree of difficulty were investigated. RESULTS: Video analysis was possible in 99 of 116 patients. Decapsulation difficulty in decapsulation was deemed as being grade I in 32 patients, grade II in 31 patients, grade III in 20 patients and grade IV in 16 patients. Preoperative dutasteride therapy was the only factor associated with an increasing level of difficulty in decapsulation during holmium laser enucleation of the prostate. CONCLUSIONS: Although preoperative dutasteride therapy effectively reduces intraoperative blood loss, surgeons with limited experience should be careful with the use of dutasteride, because its administration might increase surgical difficulty during holmium laser enucleation of the prostate.

Venous thromboembolism after urological surgery.

PURPOSE: We determined the rates of deep venous thromboembolism and pulmonary embolism after common urological procedures in the United States. MATERIALS AND METHODS: The NSQIP database was used to identify common urological procedures performed between January 1, 2005 and December 31, 2011. A total of 82,808 patients were included in the study. RESULTS: Overall 633 (0.76% of 82,808 subjects) deep venous thromboses occurred within 30 days of surgery in this cohort of patients treated with common urological procedures. Among procedures performed at least 500 times the rates of deep venous thrombosis were highest for cystectomy/urinary diversion (3.96% [71/1,792]), partial cystectomy (2.35% [17/722]) and open radical nephrectomy (1.67% [45/2,702]). The rates of deep venous thrombosis were lowest in patients undergoing laparoscopic colpopexy (0.00% [0/707]), placement of a female sling (0.08% [9/10,648]) and hydrocelectomy/spermatocelectomy/varicocelectomy (0.13% [3/2,333]). A total of 349 (0.42%) pulmonary embolisms occurred in this cohort, with cystectomy/urinary diversion having the highest rate overall (2.85% [51/1,792]). Multivariate logistic regression revealed that age greater than 60 years, functional status, history of disseminated cancer, congestive heart failure, anesthesia time greater than 120 minutes and chronic steroid use were independently associated with the formation of deep venous thrombosis/pulmonary embolism. A limitation of the study is that no data were available on thromboembolic prophylaxis. CONCLUSIONS: While deep venous thrombosis and pulmonary embolism are uncommon after urological surgery, this study is the first to our knowledge to provide a comprehensive comparison of deep venous thrombosis/pulmonary embolism rates across a full spectrum of various urological procedures in American patients. This study should give the reader a better understanding of the exact risk faced by the patient when undergoing common urological procedures.

Evaluation of surgical conditions during laparoscopic surgery in patients with moderate vs deep neuromuscular block.

BACKGROUND: The routine use of neuromuscular blocking agents reduces the occurrence of unacceptable surgical conditions. In some surgeries, such as retroperitoneal laparoscopies, deep neuromuscular block (NMB) may further improve surgical conditions compared with moderate NMB. In this study, the effect of deep NMB on surgical conditions was assessed. METHODS: Twenty-four patients undergoing elective laparoscopic surgery for prostatectomy or nephrectomy were randomized to receive moderate NMB (train-of-four 1-2) using the combination of atracurium/mivacurium, or deep NMB (post-tetanic count 1-2) using high-dose rocuronium. After surgery, NMB was antagonized with neostigmine (moderate NMB), or sugammadex (deep NMB). During all surgeries, one surgeon scored the quality of surgical conditions using a five-point surgical rating scale (SRS) ranging from 1 (extremely poor conditions) to 5 (optimal conditions). Video images were obtained and 12 anaesthetists rated a random selection of images. RESULTS: Mean (standard deviation) SRS was 4.0 (0.4) during moderate and 4.7 (0.4) during deep NMB (P<0.001). Moderate block resulted in 18% of scores at the low end of the scale (Scores 1-3); deep block resulted in 99% of scores at the high end of the scale (Scores 4 and 5). Cardiorespiratory conditions were similar during and after surgery in both groups. Between anaesthetists and surgeon, there was poor agreement between scores of individual images (average κ statistic 0.05). CONCLUSIONS: Application of the five-point SRS showed that deep NMB results in an improved quality of surgical conditions compared with moderate block in retroperitoneal laparoscopies, without compromise to the patients' peri- and postoperative cardiorespiratory conditions. Trial registration The study was registered at clinicaltrials.gov under number NCT01361149.

Interobserver variability of Clavien-Dindo scoring in urology.

OBJECTIVES: To assess the interobserver variability of Clavien-Dindo scoring in urology. METHODS: A thematic survey was carried out simultaneously in nine Polish urological centers among 171 responders - 81 urologists and 90 urologists-in-training, made up of 16 women and 155 men. After Clavien-Dindo classification was presented, respondents were asked to grade nine typical urological complications according to Clavien-Dindo classification. Interobserver agreement, reproducibility of answers, as well as the influencing factors were analyzed. Questions in the survey related to complications of variable severity after basic urological operations, including four open, one laparoscopic and four endourological. RESULTS: Agreement on the grade of complication was moderate (κ = 0.45) and it was noticed in 69% of respondents (range 38-87%). No effect of surgical approach (classic vs endoscopic, 70% vs 67%, P = 0.64), or physician professional experience (resident vs urologist, 71% vs 66%, P = 0.77) was observed. The most significant discrepancies were found in cases of local complications after transurethral surgery (accordance in 39%) and laparoscopic radical prostatectomy (accordance in 55%), and in cases of severe general complications after Bricker operation (accordance in 58%). CONCLUSIONS: The variability of Clavien-Dindo classification scoring among urologists is significant. Thus, the Clavien-Dindo classification might require detailing before its eventual implementation in urology, together with appropriate training of specialists. However, despite some disadvantages, the simplicity, reproducibility and logical scheme of the Clavien-Dindo classification make it a promising tool for quality assessment in different fields of urology.

Is It Worth the Sweat? Prehabilitation in Uro-oncology: A Mini Review.

In several surgical specialities, exercise as part of a prehabilitation program enhances recovery. However, for uro-oncological patients, evidence up to 2020 did not demonstrate significant benefits in terms of postoperative complications or hospital length of stay (LOS). We reviewed the literature from 2020 to 2023 and screened 205 reports, of which four full texts were included. Two retrospective cohort studies, despite having potential confounding risks, indicated that preoperative exercise might reduce LOS. One of these studies also suggested a lower likelihood of complications. Present evidence hints at the potential benefits of embedding exercise in prehabilitation for uro-oncological patients, particularly for short-term functional results. However, evidence on a direct effect on postoperative complications and LOS is still inconclusive. Future research should prioritise identification of specific exercises (eg, anaerobic vs aerobic, strength training, endurance, or respiratory exercises) that yield the most cost-effective benefits. PATIENT SUMMARY: Recent studies suggest that exercising before surgery might help people with urological cancers to improve their short-term fitness. More research is needed to see if exercise before surgery shortens hospital stays or reduces complications.

Catheter-associated meatal pressure injuries (CAMPI) in patients with long-term urethral catheters-a cross-sectional study of 200 patients.

Background: Indwelling urethral catheters (IDC) are ubiquitous to healthcare settings, and are associated with many familiar risks like haematuria, infections, bladder spasms and stones. However, a less known complication is catheter-associated meatal pressure injury (CAMPI), especially in those with long-term IDCs. The objective of this study was to explore the prevalence, associated features and management of CAMPI in adults with a long-term IDC. Methods: A cross-sectional multi-centre study was undertaken of 200 adults with a long-term IDC across regional south-west Queensland, Australia between June 2019 to June 2021. The prevalence of CAMPI was determined by clinical examination, voluntary surveys completed by participants and documentation in medical records. Key IDC statistics included total duration of IDC, location of IDC changes, IDC size, type and fixation. Results: Out of 200 adults with a long-term IDC, 9% (18/200) had a CAMPI. There was a higher prevalence of male CAMPI (17/169, 10%) compared to female CAMPI (1/31, 3%). The median time to identification of a CAMPI after initial IDC insertion was 12 weeks (2-136 weeks), but occurred as soon as 2 weeks. CAMPI formation was associated with IDC changes in the community, impaired mobility and congestive cardiac failure (CCF). CAMPI were mostly treated by conservative means given the frailty of the population. Conclusions: Poor mobility, community-managed IDCs, and CCF were all found to have statistically significant associations with the development of CAMPI. CAMPI represents an important and underserved iatrogenic complication within urology practice, and greater awareness is needed to prevent it in vulnerable patients with long-term IDCs.

Outcomes of urethral meatal preservation ventral urethroplasty for female urethral stricture: a series of cases.

Objective: To present a series of cases with our initial experience and short-term outcomes of a modified vaginal mucosal flap urethroplasty. Methods: Patients diagnosed with urethral stricture and operated by the same operative technique between January 2012 and January 2018 were followed for at least 6 months. Uroflowmetry and clinical outcomes were evaluated. Results: Nineteen patients were included with an average age of 56.4 years, mean preoperative Qmax of 5.3 ml/s, and PVR of 101.4 mL. After 6 months of the procedure, the mean Qmax improved to 14.7 mL/s (p<0.05), PVR decreased to 47.3 mL (p<0.05), and 84.2% of all patients reported improvement in clinical self-reported symptoms. There was an improvement in symptoms such as voiding effort in 84.2% of patients, weak stream (89.5%), and recurrent urinary tract infection (85.7%). The success rate (absence of symptoms and normal Qmax with no significant PVR) of the procedure was 84.2%. Conclusion: The described technique was considered effective for the treatment of female urethra stricture, with a high clinical success rate and an objective improvement of Qmax and decrease in PVR after 6 months of the procedure.

Use of Clavien-Dindo classification in reporting and grading complications after urological surgical procedures: analysis of 2010 to 2012.

PURPOSE: We determined the use of the Clavien-Dindo classification in urological articles. We also assessed the recent trend in the use of different postoperative complication reporting classifications by authors in major journals from 2010 to 2012. MATERIALS AND METHODS: We reviewed all articles from 5 major urological journals published between January 2010 and October 2012. All studies reporting surgical outcomes were included in analysis and individually assessed after retrieving the full text. We recorded the use of complication classifications with particular emphasis on the Clavien-Dindo classification. RESULTS: A total of 907 articles mentioned surgical outcomes, of which 137 reported no complications. A descriptive classification was the most common method (483 of 770 articles or 62.7%), followed by the Clavien-Dindo classification (256 of 770 or 33.3%). Use of the Clavien-Dindo classification in articles from all 5 journals that discussed surgical outcomes increased from 21.4% in 2010 to 50.2% in 2012. Of the 770 articles 287 (37.3%) used any standardized criteria for surgical outcome reporting in 2010 to 2012. Of the 287 articles that reported surgical outcomes the Clavien-Dindo classification was used in 256 (89.5%). CONCLUSIONS: Increasing use of classification systems was seen in the most recently published articles. When a system was adopted by authors, the Clavien-Dindo classification was used most frequently. While there has been increased use of standardized reporting systems in articles mentioning surgical complications, there is room for increased implementation.

Effective and Economical Option of Anesthesia in Retrograde Intrarenal Surgery.

Background: There is only limited data in the literature showing the effect of anesthesia methods on the success of retrograd intrarenal surgery. The aim of this study was to compare and evaluate retrograd intrarenal surgery cases performed under spinal and general anesthesia in terms of effectiveness, cost, hospitalization time and complications. Methods: A total of 337 patients who underwent retrograd intrarenal surgery due to kidney stones between 2014 and 2019 were retrospectively evaluated. In our study, the patients were divided into two groups according to the anesthesia method administered: Group 1 consisted of 172 patients who received spinal anesthesia and Group 2 comprised 165 patients administered general anesthesia. Both groups were compared in terms of demographic data, localization and size of stone, radiographic stone density, operation time, complications, need for postoperative analgesia, length of hospitalization, and stone free rate. Results: The cost of general anesthesia was significantly higher compared to that of spinal anesthesia (p < 0.001). The analgesia application administered within the first six postoperative hours was significantly higher in the general anesthesia group (p < 0.001). In other findings, there was no statistically significant difference between the two groups. Conclusion: Retrograd intrarenal surgery can be performed with similar safety and effectiveness under both general and spinal anesthesia. However, spinal anesthesia seems to be more advantageous due to the patients' lower need for analgesics in the early postoperative period and the lower cost of the anesthetics used.

Preclinical evaluation of the Versius surgical system: A next-generation surgical robot for use in minimal access prostate surgery.

Objectives: To evaluate the Versius surgical system for robot-assisted prostatectomy in a preclinical cadaveric model using varying system setups and collect surgeon feedback on the performance of the system and instruments, in line with IDEAL-D recommendations. Materials and methods: Procedures were performed in cadaveric specimens by consultant urological surgeons to evaluate system performance in completing the surgical steps required for a prostatectomy. Procedures were conducted using either a 3-arm or 4-arm bedside unit (BSU) setup. Optimal port placements and BSU layouts were determined and surgeon feedback collected. Procedure success was defined as the satisfactory completion of all steps of the procedure, according to the operating surgeon. Results: All four prostatectomies were successfully completed; two were completed with a 3-arm BSU setup and two using a 4-arm BSU setup. Small adjustments were made to the port and BSU positioning, according to surgeon preference, in order to complete the surgical steps. The surgeons noted some instrument difficulties with the Monopolar Curved Scissor tip and the Needle Holders, which were subsequently refined between the first and second sessions of the study, in line with surgeon feedback. Three cystectomies were also successfully completed, demonstrating the capability of the system to perform additional urological procedures. Conclusions: This study provides a preclinical assessment of a next-generation surgical robot for prostatectomies. All procedures were completed successfully, and port and BSU positions were validated, thus supporting the progression of the system to further clinical development according to the IDEAL-D framework.

Opioid Stewardship in Urology: Quality Improvement Summit 2018.

INTRODUCTION: We summarize the 2018 AUA (American Urological Association) Quality Improvement Summit, Opioid Stewardship in Urology, highlighting appropriate urological opioid use as well as reviewing programs that have been successful in reducing opioid prescribing. The AUA brought together nearly 100 attendees from across the United States, including clinicians who specialize in urology and other specialties, as well as researchers, government officials and others. METHODS: The 2018 AUA Quality Improvement Summit was a 1-day meeting held at AUA headquarters in Linthicum, Maryland. Talks and panels highlighted opioid stewardship programs and emphasized research on the nature and management of postoperative pain. RESULTS: The impact of the opioid epidemic is profound and the contribution of postoperative prescribing is noteworthy (eg 6% of opioid naïve patients demonstrate new persistent use habits after surgery and up to 70% of opioid pills prescribed after surgery go unused). Speakers raised awareness of these facts and detailed opportunities to improve, including prudent prescribing, opioid reclamation, use of nonopioid alternatives, and outreach and education. CONCLUSIONS: The 2018 AUA Quality Improvement Summit provided a platform for urologists to discuss the opioid epidemic and to learn strategies for combatting this issue from multidisciplinary experts. Physician led opioid stewardship and research, facilitated by this Summit, may enhance the quality and safety of medical care and improve the lives of patients, their families and their communities.

A Systematic Review on Guidelines and Recommendations for Urology Standard of Care During the COVID-19 Pandemic.

CONTEXT: The first case of the new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), was identified in Wuhan, China, in late 2019. Since then, the coronavirus disease 2019 (COVID-19) outbreak was reclassified as a pandemic, and health systems around the world have faced an unprecedented challenge. OBJECTIVE: To summarize guidelines and recommendations on the urology standard of care during the COVID-19 pandemic. EVIDENCE ACQUISITION: Guidelines and recommendations published between November 2019 and April 17, 2020 were retrieved using MEDLINE, EMBASE, and CINAHL. This was supplemented by searching the web pages of international urology societies. Our inclusion criteria were guidelines, recommendations, or best practice statements by international urology organizations and reference centers about urological care in different phases of the COVID-19 pandemic. Our systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Of 366 titles identified, 15 guidelines met our criteria. EVIDENCE SYNTHESIS: Of the 15 guidelines, 14 addressed emergency situations and 12 reported on assessment of elective uro-oncology procedures. There was consensus on postponing radical prostatectomy except for high-risk prostate cancer, and delaying treatment for low-grade bladder cancer, small renal masses up to T2, and stage I seminoma. According to nine guidelines that addressed endourology, obstructed or infected kidneys should be decompressed, whereas nonobstructing stones and stent removal should be rescheduled. Five guidelines/recommendations discussed laparoscopic and robotic surgery, while the remaining recommendations focused on outpatient procedures and consultations. All recommendations represented expert opinions, with three specifically endorsed by professional societies. Only the European Association of Urology guidelines provided evidence-based levels of evidence (mostly level 3 evidence). CONCLUSIONS: To make informed decisions during the COVID-19 pandemic, there are multiple national and international guidelines and recommendations for urologists to prioritize the provision of care. Differences among the guidelines were minimal. PATIENT SUMMARY: We performed a systematic review of published recommendations on urological practice during the coronavirus disease 2019 (COVID-19) pandemic, which provide guidance on prioritizing the timing for different types of urological care.
