RESUMO

"The new frontier of robotic surgery is well under way. Current research and development is rapidly progressing, allowing for the creation of many new robotic companies. Each company has its own identity and platform for what their vision for the future entails. The competition generated between these companies will shortly be forcing newer, cheaper, more accessible robotic systems worldwide."

RESUMO

Robotically assisted laparoscopic techniques may be used for proximal and distal ureteral strictures. Distal strictures may be approached with ureteroneocystotomy, psoas hitch, and Boari flap. Ureteroureterostomy, buccal mucosa graft ureteroplasty, and appendiceal flap ureteroplasty are viable techniques for strictures anywhere along the ureter. Ileal ureteral substitution is reserved for more extensive disease, and autotransplantation is reserved for salvage situations.

RESUMO

"Theatre acting is the operation with a scalpel, movie acting is an operation with a laser". Michael Caine. Being the instrument in hands of urologist laser is much more than a single-application device. Its applicability is deeply dependent on physical properties, settings, and environment. With knowledge of how the device work, why it affects the tissue, and how this laser-tissue interaction goes surgeon can shape further clinical work to choose the best devices or techniques of surgery. Tailoring the laser effects on the needs of the patient. In this paper, we tried to briefly describe what a laser device consists of, the most important laser-tissue interactions that are necessary for understanding the operation of the laser, and the main laser systems that are used in urology


Michael Caine dijo que las actuaciones de quirófano son con bisturí y las actuaciones en películas son con láser. En manos de urólogos, el láser es mucho más que una técnica. Su aplicabilidad depende de las habilidades físicas, la disposición de los elementos y el ambiente. El conocimiento del láser permite al cirujano escoger la técnica correcta para cada caso. En este manuscrito, describimos en qué consiste el láser, las interacciones con el tejido y los principales tipos de láser en urología

RESUMO

PURPOSE: We evaluated mid urethral sling outcomes in overweight and obese patients compared to normal weight patients and identified risk factors for failure in this population. MATERIALS AND METHODS: Records of 688 women between January 2004 and July 2017 were retrospectively reviewed. Patients received urodynamic studies, 1-hour pad test, Urogenital Distress Inventory-6 and Incontinence Impact Questionnaire-7, and were divided into normal weight, overweight and obese. Objective cure at 1 year was defined as no involuntary urine leakage during filling cystometry and pad test less than 2 gm. Subjective cure was established by negative response to question 3 on Urogenital Distress Inventory-6. McNemar's test, chi-square test, Mann-Whitney U and Fisher's exact test were used for paired categorical variables. Independent samples t-tests and paired t-test were used for continuous parametric variables. Multivariate logistic regression was used to identify risk factors for failure. RESULTS: Objective and subjective cure in normal, overweight and obese patients was 91.4% and 89.1%, 87.5% and 86%, and 76% and 70.1%, respectively. There was no difference in surgical complications. Obese patients had worse quality of life scores preoperatively and postoperatively. Risk factors in obese patients with failed mid urethral sling included 66 years old or older (OR 2.02, 1.56-3.98), menopause (OR 4.21, 1.21-14.22), previous prolapse surgery (OR 4.57, 2.36-8.52), diabetes (OR 2.79, 1.61-5.99) and intrinsic sphincter deficiency (OR 5.06, 3.08-9.64). CONCLUSIONS: Obese women with mid urethral sling had lower objective and subjective cure at 1 year and worse quality of life scores compared to normal and overweight women. Risk factors for failure include age, diabetes, menopause, previous prolapse surgery and intrinsic sphincter deficiency.

RESUMO

Background: As a relatively new approach, popularity of pneumovesicoscopic surgery is increasing, but slower than expected due to complex nature of the procedure with efforts to overcome the difficult steps of the procedure. Bladder fixation is one of the crucial steps of the procedure. In this study, we present a novel and simple T-bar technique to overcome this difficulty. Methods: We retrospectively evaluated 24 consecutive patients (39 ureters) who underwent pneumovesicoscopic surgery with fixation of the bladder wall between December 2017 and September 2019. Results: Fixation by transabdominal suture (TS) was performed in 3 patients, while fixation by thread loops with needle in 3 and T-bar device in 18. Tearing of the bladder wall was encountered in 2 patients in TS, in 2 patients with thread loop groups, but none in the T-bar group. Conversion to open surgery was necessary in 3 patients in the T-bar group, but only 1 was related with the fixation technique. Conclusions: T-bar technique is an inexpensive and simple solution providing stable and reliable bladder wall and working port fixation during pneumovesicoscopy.

RESUMO

BACKGROUND: Robotic surgery presents a challenge to effective teamwork and communication in the operating theatre (OR). Our objective was to evaluate the effect of using a wireless audio headset device on communication, efficiency and patient outcome in robotic surgery. METHODS AND FINDINGS: A prospective controlled trial of team members participating in gynecologic and urologic robotic procedures between January and March 2015. In the first phase, all surgeries were performed without headsets (control), followed by the intervention phase where all team members used the wireless headsets. Noise levels were measured during both phases. After each case, all team members evaluated the quality of communication, performance, teamwork and mental load using a validated 14-point questionnaire graded on a 1-10 scale. Higher overall scores indicated better communication and efficiency. Clinical and surgical data of all patients in the study were retrieved, analyzed and correlated with the survey results. The study included 137 procedures, yielding 843 questionnaires with an overall response rate of 89% (843/943). Self-reported communication quality was better in cases where headsets were used (113.0 ± 1.6 vs. 101.4 ± 1.6; p < .001). Use of headsets reduced the percentage of time with a noise level above 70 dB at the console (8.2% ± 0.6 vs. 5.3% ± 0.6, p < .001), but had no significant effect on length of surgery nor postoperative complications. CONCLUSIONS: The use of wireless headset devices improved quality of communication between team members and reduced the peak noise level in the robotic OR.

RESUMO

PURPOSE OF REVIEW: Ureteral stents are necessary in the routine practice of an urologist. Choosing the correct stent and being aware of the options available will allow urologists to provide the best possible care for patients and value to the healthcare system. This review seeks to educate urologists regarding improvements in stent technology currently available or in development. RECENT FINDINGS: Research from around the world is underway to discover an ideal stent - one that is comfortable for patients, resists infection and encrustation and is affordable for hospital systems. Stent design alterations and stent coatings are revealing reductions in encrustation and bacterial colonization. Biodegradable stents and magnetic stents are being tested to prevent the discomfort of cystoscopic removal. Intraureteral stents are proving efficacious while eliminating an irritating coil from the bladder and the symptoms associated with it. SUMMARY: The studies highlighted in this review provide encouraging results in the pursuit of the ideal stent while opening discussion around new concepts and further areas of research.

RESUMO

Due to a safety alert issued by the US Food and Drug Administration (FDA) in 2011 for transvaginal mesh implants to treat female prolapse as a result of numerous reports of complications such as infection, chronic pain, dyspareunia, vaginal erosion, shrinkage and erosion into other organs nearly all industrial products have been withdrawn from the market in the meantime. The United Kingdom, Australia, and New Zealand extended warnings and prohibitions even on the implantation of midurethral slings (TVT, TOT). In view of these current international controversies regarding the use of implanted materials for the treatment of stress incontinence and prolapse and the lack of clear guidelines for the use of biomaterials, the opinion of the Working Group on Urological Functional Diagnostics and Female Urology should provide clarity. The Opinion is based on the SCENIHR Report of the "European Commission's Scientific Committee on Emerging and Newly Identified Health Risks", the "Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence" and in compliance with relevant EAU and national guidelines and the opinion of the Association for Urogynaecology and Plastic Pelvic Floor Reconstruction (AGUB eV). In addition, recommendations are given for the future handling of implants of slings and meshes for the treatment of stress incontinence and prolapse from a urologic viewpoint.

RESUMO

BACKGROUND: Ureteral stents with magnetic tips (Blackstar©) were recently approved for use in Canada. To our knowledge this is the first published evidence of their use in pediatric patients. Traditionally, pediatric stent insertion and removal are performed under general anesthetic. Magnetic stents have three main benefits in pediatric patients; cost savings, decreased OR time and reduced general anesthetic exposure. METHODS: This study was a proof of concept pilot, ran from May 2017-May 2018 to demonstrate the safety and efficacy of magnetic stents in pediatric patients. Patients undergoing ureteroscopy, ureteric re-implantation, and pyeloplasty with simultaneous magnetic stent insertion. Forty (40) patients had regular double J stents removed under anesthesia and served as control cases, and 40 patients had a magnetic double J at initial surgery at two different sites, CHU de Quebec and Alberta Children's Hospital. RESULTS: Overall, 39 magnetic stents were successfully retrieved without general anesthetic, representing a retrieval failure rate of only 2.5%. CONCLUSION: As demonstrated in our research, magnetic stents represent a safe and equally effective alternative to traditional stents, especially in a pediatric patient. This is because, at worst, if retrieval of the magnetic stent fails, traditional cystoscopic removal can be performed, so nothing is lost. STUDY TYPE: Case-control study. LEVEL OF EVIDENCE: Level III.

RESUMO

INTRODUCTION: The aim of our study was to elucidate the impact of patients' physical characteristics on the movement of target organs and anatomical landmarks by comparing supine and lateral CT images. METHODS: This study consisted of 55 patients who underwent laparoscopic surgery in the lateral position. CT images of the area between the abdomen and pelvis were taken preoperatively with patients in both supine and lateral positions. We measured the moving distance of target organs and anatomical landmarks on the body surface used for access port settings. We investigated which covariates from patients' body composition most affected moving distance in correlation analysis. Then, using multiple linear regression analysis, we examined whether we could predict the movement of target organs and anatomical landmarks solely based on information obtained from supine CT images. RESULTS: The moving distance of both the hilum of the kidney and the outer edge of the rectus abdominis muscle were significantly associated with some physical characteristics. Multiple regression analysis showed that a larger visceral fat area could be a useful index for predicting the movement of the kidney toward the counter side. Lower CT density of back muscles and higher BMI could be useful indexes for predicting the movement of the rectus abdominis muscle. CONCLUSION: Our results suggested that body composition characteristics obtained from preoperative CT images can help predict the movement of target organs and anatomical landmarks used to determine proper port-site placement for laparoscopic surgery performed with the patient in the lateral position.

RESUMO

INTRODUCTION: The da Vinci SP® Robotic Surgical Platform (Intuitive Surgical) was recently introduced to overcome triangulation and motion restriction during laparoendoscopic single-site surgery. The authors describe a pure, single-site, robot-assisted, laparoscopic pyeloplasty (RALP) using the da Vinci SP System in a pediatric patient. MATERIAL AND METHODS: A 10-year-old patient with ureteropelvic junction obstruction underwent pyeloplasty conducted using the da Vinci SP® System. Retrospective perioperative and immediate postoperative outcomes were investigated. RESULTS: Surgery was completed with pure single-site surgery without additional port placement or standard multiport conversion. The total operation time was 211 min, and the console time was 90 min. The docking time was much greater than that of previous pyeloplasty operations using multiport system. This result may be because of difficulties caused by bulky instrumentation entering the pneumoperitoneum. The estimated blood loss was minor, and there were no intraoperative or perioperative complications. Ureteral stent was removed after 4 weeks. Cosmetic outcomes were satisfactory. CONCLUSIONS: Pure, single-site RALP using da Vinci SP® System seems feasible in aging children. Additional studies involving more patients, younger children, and long-term outcomes are required.

RESUMO

PURPOSE: To evaluate the long-term cure and complication rates of the canal transobturator tape (TOT) procedure for stress urinary incontinence (SUI) in females and assess how to reduce mesh erosion in TOT surgery. MATERIALS AND METHODS: The canal TOT procedure was developed in 2009 and was effective in mitigating the complications of the original TOT procedure in the short-term follow-up. This study was designed for a long-term follow-up. Between October 2006 and December 2010, 232 consecutive women with stress and mixed urinary incontinence underwent the canal TOT procedure. All patients were followed up by urological examination and self-assessment questionnaires. We performed urodynamic studies in patients with pure SUI symptoms and pelvic examination for all patients 5 years post-surgery. RESULTS: A minimum 5 years follow-up data were available for 144 patients. Complications were evaluated according to the Clavien-Dindo classification. Vaginal mesh erosion was reported in 2 patients (1.4%), and the mesh was surgically removed. No bladder or urethral mesh erosion were observed. The subjective and objective cure rates at 5 years were 77.8 and 94.5% respectively. CONCLUSIONS: Canal TOT procedure is an effective minimally invasive procedure with satisfactory results for female SUI in the long term. Compared to the rate of mesh erosion after the original TOT procedure, this technique might be useful in preventing mesh erosion because the mesh is always anatomically well positioned.

RESUMO

The increase of medical knowledge and technical innovations together with the demographic change represent a challenge for the new conception of guidelines and clinical studies. The present S2k guidelines, which are exclusively concerned with kidney and ureteral stones, should support the treatment of urolithiasis in hospitals and private practices and provide information on urolithiasis for patients. Increasing interdisciplinary collaboration in stone treatment is also demonstrated in the number of professional and working groups participating in the update of the new guidelines. The present S2k guidelines emerged from a consensus process and demonstrate the current recommendations in step with actual practice. They provide decision-making guidance for diagnostics, treatment and metaphylactic measures based on expert opinions and available published fundamental evidence from the literature.

RESUMO

Intravesical instillation of Bacille Calmette-Guèrin (BCG) is the standard adjuvant treatment for high-risk non muscle invasive bladder cancer (NMIBC). Since its mechanism of action is supposed to be linked to the immune system efficiency and senescence could negatively affect this efficiency, BCG efficacy in the elderly has been questioned. This study aimed to assess the impact of age on BCG efficacy and safety in patients with high-grade T1 bladder cancer (BC).Among 123 patients with high-grade T1 BCG scheduled for BCG treatment, 82 were <75 year-old (group A) and 41 were ≥75 year-old (group B). Follow-up: urine cytology and cystoscopy every 3 months for the first 2 years, every 6 months for the third year, and then yearly. Tumor recurrence was defined as pathological evidence of disease at the bladder biopsy; tumor progression was defined as pathological shift to muscle invasive disease at the bladder biopsy or the imaging techniques showing recurrent BC and distant metastasis likely related to it.The median follow-up was 65 months (range 11-152). Recurrence occurred in 35 patients, 19 (23.2%) in the group A and 16 (39%) in the group B. Progression occurred in 18 patients, 12 (14.6%) in the group A and 6 (14.6%) in the group B. Recurrence free rate was similar in both groups up to 2 years. The 5 years progression rate was almost the same in both groups A and B (85.9% vs 84.7%), whereas the 5 years cancer-specific survival (CSS) was 92.6% in the group A and 85.4% in the group B. Of the 18 patients with progression, 11 underwent cystectomy; 12 patients died because of their BC. Kaplan-Meier plots pointed out no difference in recurrence-free, progression-free, and CSS between the 2 groups. Adverse events were similar in the 2 groups. Only 4 (3.3%) patients, 2 (2.4%) in the group A and 2 (4.8%) in the group B, experienced mild adverse reactions compatible with treatment.Elderly patients with high-grade T1 BC are not poorer candidates to BCG treatment, as they had similar benefit and adverse reactions than those aging ≥75 years.

RESUMO

BACKGROUND: Subcutaneous ureteral bypass (SUB) device placement is an increasingly popular treatment option for decompression of ureteral obstruction in cats. Mineralization occlusion of the device occurs in a minority of cases but is the most common complication. OBJECTIVE: To evaluate a 2% tetrasodium ethylenediaminetetraacetic acid (tEDTA) solution for treatment of mineralization occlusion in cats with SUBs. ANIMALS: Six client-owned cats (8 obstructed devices). METHODS: Case series. Each cat was found to have device occlusion based on a combination of ultrasound examination, SUB irrigation, and failure to identify another cause of device obstruction. Each SUB was drained, irrigated using sterile saline, and infused with 1-2 mL of 2% tEDTA solution. Success was defined as normalization of flow during subsequent ultrasound visualization while irrigating. The volume and frequency of tEDTA instillations, time to achieve device patency, follow-up biochemical and ultrasound findings, and future reobstruction events were recorded. RESULTS: Resolution of mineralization was documented in all 8 SUBs. Reobstruction events occurred in 2 cats, all of which resolved after additional tEDTA infusions, but 1 cat ultimately required device exchange at 356 days from the first tEDTA infusion. In 1 cat, a single infusion was prematurely discontinued because of persistent pelvic dilatation after 1.25 mL of tEDTA had been instilled. No complications were observed. CONCLUSIONS AND CLINICAL IMPORTANCE: Tetrasodium EDTA infusions can be safely considered as a treatment option for mineralized SUB devices in cats. This solution was easily infused, well tolerated, and avoided the need for SUB device exchange in the majority of cats in which it was used.

RESUMO

BACKGROUND: The aim of this study was to examine ureteral stricture rate after the use of UAS in an unstented ureter and compare complications of smaller vs. larger-caliber UAS. METHODS: We conducted a retrospective analysis of consecutive RIRS for renal stones, with the use of UAS in unstented ureters. We excluded cases with previous ureteroscopies, who carried ureteral stent or nephrostomy, had impacted stones, underwent radiation treatment, or had urinary tract malignancies. The primary outcome was formation of ureteral strictures diagnosed by hydronephrosis in ultrasound test and late secretion in dynamic renal scan. Secondary outcome was stone-free-rate (SFR) and complications. In addition, we compared safety and efficacy of smaller (9.5/11.5Fr) vs. larger-caliber (12/14Fr) UAS. RESULTS: The cohort included 165 patients with a median follow-up time of 115 days. There was no case of ureteral stricture formation after the use us UAS, despite using a larger-caliber UAS in nearly half the cases. Larger-caliber UAS was not associated with more complications compared to the smaller-caliber one (p = 0.780). SFR was non-significantly higher in the larger-caliber UAS group (p = 0.056), despite having a larger stone burden, and only stone number was associated with SFR (p = 0.003). CONCLUSIONS: These data suggest that the use of UAS during RIRS in an unstented ureter is safe and does not involve ureteral stricture formation after one procedure. Furthermore, the use of wider sheaths was not found to be associated with higher complications rate.

RESUMO

OBJECTIVES: To describe a new technique for robot-assisted AMS-800 artificial urinary sphincter (AUS) bladder neck implantation in women. PATIENTS AND METHODS: We reviewed the medical files of patients who underwent robot-assisted AUS implantation between March 2017 and November 2018 at our centre. All of the implantations were performed using a posterior approach to the bladder neck in order to avoid blind dissection and the risk of vaginal and/or bladder injury. This strategy was viewed as an alternative to the anterior robot-assisted implantation recently described. The AUSs were activated 5 weeks after implantation. Patients were followed up at 3, 6 and 12 months, then annually. RESULTS: Eight patients, with a median age of 64 years, underwent robot-assisted AUS implantation via a posterior approach to the bladder neck. The median preoperative pad weight was 300 g/24 h. The median operating time was 244 min. No peri-operative vaginal and or bladder injuries were observed. At a median of 12 months of follow-up, all the AUSs were functional. Five patients required no protection (62.5%), three had day protection (37.5%), and all said they were satisfied except for one patient (12.5%) who requested treatment for persistent urge incontinence. CONCLUSION: Robot-assisted AUS implantation in women via a posterior approach to the bladder neck is a procedure that is simple, reproducible and safe. The short-term functional results are satisfactory and comparable to those obtained via an open approach. A more long-term comparison of the efficacy and longevity of AUSs implanted using this posterior approach is needed to confirm its benefit compared with the anterior robot-assisted approach and the classic open technique.

RESUMO

OBJECTIVES: To analyse functional outcomes and complication rates of artificial urinary sphincter (AUS) implantation with a distal bulbar double cuff (DC) for the treatment of stress urinary incontinence (SUI) in men with and without a history of external beam radiotherapy (RT). PATIENTS AND METHODS: Data of all patients undergoing AUS implantation with a distal bulbar DC (DC-AUS) were collected prospectively from 2009 to 2015. Indications for DC implantation were based on urethral risk factors in terms of RT and previous proximal bulbar urethral interventions including, endoscopic or open surgery for urethral stricture or SUI. Implantation was carried out to a standardised protocol. Activation of the AUS was performed 6 weeks after implantation. Further follow-up (FU) included pad test, uroflowmetry, post-void residual urine measurements, radiography, and a standardised questionnaire. Continence and complication rates were compared between patients with a history of RT and non-RT patients. Explantation-free survival was estimated using Kaplan-Meier curves and the log-rank test. Firth's penalized Cox-regression analyses were performed to analyse proportional hazard ratios for explantation. RESULTS: In all, 150 men (median age 70 years, interquartile range [IQR] 66-74) after DC-AUS implantation were available for analysis. Overall, 73 men (48.7%) had a history of RT. The median (IQR) FU was 24 (7.25-36) months. Baseline clinical characteristics only differed regarding previous open SUI surgery (P = 0.016). Social and objective continence was achieved in 94.8% and 84.3% of all patients treated by implantation of a DC-AUS, respectively. Between the RT and non-RT patients there were no statistically significant differences in continence rates [social continence: 100% vs 90.2% (P = 0.194); objective continence: 87% vs 82% (P = 0.877)]. For complications rates there were no significant differences between RT and non-RT patients after DC-AUS implantation [infection (P = 0.09), erosion (P = 0.31), mechanical failures (P = 0.14)]. According to Kaplan-Meier analysis explantation rates in patients with a history of RT (26.0%) vs non-RT patients (20.8%), estimated explantation-free survival, and AUS durability, did not differ significantly (log-rank P = 0.219). CONCLUSION: Our data from a large institutional series indicate DC-AUS implantation to be an effective and safe treatment strategy in men with SUI and a history of RT.

RESUMO

OBJECTIVE: To determine if there is a difference between postoperative urinary infection rates after retrograde intra-renal surgery (RIRS) when ureteral access sheath (UAS) was used or not used. MATERIALS AND METHODS: We retrospectively analyzed the medical records of all patients who underwent RIRS at our institution between January 2016 and October 2018. RESULTS: 129 patients were included in the study. The mean age of the patients was 48.8 ± 12.1 years; 94 patients were male and 35 were female. The mean stone size (largest diameter), stone attenuation and stone volume were 15.3 ± 5.8 mm, 1038 ± 368 HU and 1098 ± 1031 mm3, respectively. Out of 129 patients, 81 were treated by using UAS (Group 1) and 48 were treated without use of UAS (Group 2). There was no statistically significant difference between the two groups in terms of post-operative infection (p = 0.608). However, the operative time of patients with post-operative infection was statistically higher than the other patients; 88.35 ± 22.5 min versus 59.37 ± 22.1 min (p = 0.017). In multivariate regression analysis, operation time (p = 0.02, r = 1.07) was found to be the sole predictor of post-operative infection. CONCLUSIONS: Using UAS during RIRS might reduce the intrarenal pressure and also has several advantages. However not prolonging the operation time too much could be of higher importance than UAS use in terms of preventing post-operative infection after RIRS.
