Emergency Surgery in Urology during the COVID-19 Pandemic

ABSTRACT Proposal: To highlight the indications for emergency surgery during the 2019 Coronavirus pandemic (COVID-19) that support recommendations published in midMarch 2020 by the American Confederation of Urology on its website. Materials and Methods: A bibliographic search was conducted in PubMed and Cochrane Library to perform a non-systematic review, using key words: Urology, Emergency and COVID-19, to determine recommendations for patients that should receive emergency care due to urological pathology. Results: The main recommendations and protocols in the management of different urological emergencies during the COVID-19 pandemic are reviewed and discussed. Conclusions: We are living a new condition with the COVID-19 pandemic, which obliges urologists to conform to the guidelines that appear on a daily basis formulated by multidisciplinary surgical groups to manage urological emergencies. Consequently, in this time of health crisis, we must adapt to the resources available, implementing all biosecurity measures to protect patients and all health personnel who are in charge of patient management.

Laparoscopic and robotic urology surgery during global pandemic COVID-19

ABSTRACT Known laparoscopic and robotic assisted approaches and techniques for the surgical management of urological malignant and benign diseases are commonly used around the World. During the global pandemic COVID-19, urology surgeons had to reorganize their daily surgical practice. A concern with the use of minimally invasive techniques arose due to a proposed risk of viral transmission of the coronavirus disease with the creation of pneumoperitoneum. Due to this, we reviewed the literature to evaluate the use of laparoscopy and robotics during the pandemic COVID-19. A literature review of viral transmission in surgery and of the available literature regarding the transmission of the COVID-19 virus was performed up to April 30, 2020. We additionally reviewed surgical society guidelines and recommendations regarding surgery during this pandemic. Few studies have been performed on viral transmission during surgery. No study has been made regarding this area during minimally invasive urology cases. To date there is no study that demonstrates or can suggest the ability for a virus to be transmitted during surgical treatment whether open, laparoscopic or robotic. There is no society consensus on restricting laparoscopic or robotic surgery. However, there is expert consensus on modification of standard practices to minimize any risk of transmission. During the pandemic COVID-19 we recommend the use of specific personal protective equipment for the surgeon, anesthesiologist and nursing staff in the operating room. Modifications of standard practices during minimally invasive surgery such as using lowest intra-abdominal pressures possible, controlled smoke evacuation systems, and minimizing energy device usage are recommended.

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

Differences in the percutaneous nephrolithotomy practice patterns among Latin American urologists with and without endourology training

ABSTRACT Purpose: Although the worldwide percutaneous nephrolithotomy (PCNL) practice pat- terns determined via a survey sent to members of the Endourological Society have been published, differences in PCNL practice patterns among Latin American urologists based on endourological or lithiasis training have not been published. To determine the PCNL practice patterns among Latin American urologists with and without training in endourology. Materials and Methods: The SurveyMonkey® web platform was used to develop a 27-item survey on PCNL for the treatment of renal stones, and the survey was sent via e- -mail and other electronic media to 2000 urologists from 15 Latin American countries. Endourology-trained (group 1) and nontrained urologists (group 2) were analyzed. The group results were compared using the chi-squared and Fisher's exact tests. SPSS version 20 for Windows was used for all analyses. Results: A total of 331 urologists responded to the survey (rate of 16.55%): 221 (66.7%) in group 1 and 110 (33.2%) in group 2). In groups 1 and 2, 91.9% and 63.2% performed PCNL, respectively: 85.1% and 58.5% used preoperative tomography, respectively; 12.7% and 4.7% used preoperative nephrolitometry nomograms, respectively: 45.2% and 32.1% used endoscopic combined intrarenal surgery, respectively: 68.3% and 38.7% used mul- tiple percutaneous tract realization, respectively: and 19.9% and 5.7% used minimally invasive PCNL, respectively (all p=0.0005). Conclusions: Statistically significant differences were observed in PCNL practice patterns of Latin American urologists with and without training in endourology. Specific training in endourology significantly influence the practice patterns of Latin American urologists.

Establishment of Reference Ranges for Prostate Volume and Annual Prostate Volume Change Rate in Korean Adult Men: Analyses of a Nationwide Screening Population

We aimed to determine normal reference ranges for prostate volume (PV) and annual PV change rate in a Korean nationwide screening population. Data from men who underwent a routine health check-up were collected from 13 university hospitals. The cohort comprised men aged > or =40 yr who had undergone 2 or more serial transrectal ultrasonographies. Men with initial PV>100 mL; serum PSA level>10 ng/mL; PV reduction>20% compared with initial PV, or who had history of prostate cancer or prostate surgery, were excluded. Linear regression and mixed effects regression analyses were used to predict mean PV and longitudinal change in PV over time. A total of 2,967 men formed the study cohort. Age, body mass index (BMI), and serum prostate-specific antigen (PSA) level were found to be significant predictors of PV. A predicted PV table, with a 95% confidence interval (CIs), was developed after adjusting for these 3 variables. Annual PV change rate was 0.51 mL/year (95% CI, 0.47-0.55). Annual PV change rate according to age was 0.68 mL/year, 0.84 mL/year, 1.09 mL/year, and 0.50 mL/year for subjects in their 40s, 50s, 60s, and > or =70 yr, respectively. Predicted annual PV change rate differed depending on age, BMI, serum PSA level and baseline PV. From a nationwide screening database, we established age-, PSA-, and BMI-specific reference ranges for PV and annual PV change rate in Korean men. Our newly established reference ranges for PV and annual PV change rate will be valuable in interpreting PV data in Korean men.

Biochemical recurrence after radical prostatectomy: is the disease or the surgeon to blame?

PURPOSE: The PSA recurrence develops in 27 to 53 percent within ten years after radical prostatectomy (RP). We investigated the factors (disease grade and stage or the surgeon's expertise,) more likely to influence biochemical recurrence in men post-radical prostatectomy for organ-confined prostate cancer by different surgeons in the same institution. MATERIALS AND METHODS: A total of 510 patients that underwent radical prostatectomy were investigated retrospectively. Biochemical recurrence was defined as detection of a PSA level of > 0.20 ng/mL by two subsequent measurements. The causes, which are likely to influence the development of PSA recurrence, were separated into two groups as those related to the disease and those related to the surgical technique. RESULTS: Biochemical recurrence was detected in 23.5 percent (120 cases) of 510 cases. The parameters most likely to influence biochemical recurrence were: PSA level (p < 0.0001), T stage (p < 0.0001), the presence of extracapsular invasion prostate (p < 0.0001), Gleason scores (p = 0.042, p < 0.0001) and the presence of biopsy with perineural invasion (p = 0.03). The only surgical factor that demonstrated relevance was inadvertent capsular incision during the surgery that influenced the PSA recurrence (p < 0.0001). CONCLUSION: The PSA recurrence was detected in 21.6 percent of patients who had been treated with radical prostatectomy within 5 years, which indicates that the parameters related to the disease and the patient have a pivotal role in the PSA recurrence.

Is the ability to perform transurethral resection of the prostate influenced by the surgeon's previous experience?

PURPOSE: To evaluate the influence of the urologist's experience on the surgical results and complications of transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Sixty-seven patients undergoing transurethral resection of the prostate without the use of a video camera were randomly allocated into three groups according to the urologist's experience: a urologist having done 25 transurethral resections of the prostate (Group I - 24 patients); a urologist having done 50 transurethral resections of the prostate (Group II - 24 patients); a senior urologist with vast transurethral resection of the prostate experience (Group III - 19 patients). The following were recorded: the weight of resected tissue, the duration of the resection procedure, the volume of irrigation used, the amount of irrigation absorbed and the hemoglobin and sodium levels in the serum during the procedure. RESULTS: There were no differences between the groups in the amount of irrigation fluid used per operation, the amount of irrigation fluid absorbed or hematocrit and hemoglobin variation during the procedure. The weight of resected tissue per minute was approximately four times higher in group III than in groups I and II. The mean absorbed irrigation fluid was similar between the groups, with no statistical difference between them (p=0.24). Four patients (6 percent) presented with TUR syndrome, without a significant difference between the groups. CONCLUSION: The senior urologist was capable of resecting four times more tissue per time unit than the more inexperienced surgeons. Therefore, a surgeon's experience may be important to reduce the risk of secondary TURP due to recurring adenomas or adenomas that were incompletely resected. However, the incidence of complications was the same between the three groups.

Patterns in the Diagnosis and Management of Benign Prostatic Hyperplasia in a Country that does not have Country-Specific Clinical Practice Guidelines

PURPOSE: We have evaluated the patterns of diagnostic and treatment practices for benign prostatic hyperplasia (BPH) in a country that does not have country-specific clinical practice guidelines. MATERIALS AND METHODS: Probability samples were taken from the Korean Urological Association Registry of Physicians, and randomly sampled Korean urologists were asked to complete a questionnaire. The survey explored practice characteristics and attitudes, as well as diagnostic and treatment strategies, for the management of BPH. RESULTS: Of the 850 questionnaires sent, 302 were returned, and 277 of those were included in the final analysis (response rate 32.6%). For the initial evaluation, most urologists routinely used digital rectal examinations (DRE) and urinalysis. Uroflowmetry was used 34.7% of the time. Pressure-flow studies were rarely done. Symptom assessment was used in only 46.9% of cases. In addition, a significant number (58.8%) reported that treatment decisions were not based on the symptom questionnaire. Before surgery, almost all urologists routinely used DRE, urinalysis, and prostate-specific antigen tests. Of the respondents, 55.6% and 41.9% had prescribed alpha- blockers and alpha-blockers with 5-alpha reductase inhibitors, respectively. 81.2% of urologists perceived that selective alpha-blockers are different in terms of efficacy, and 82.7% felt that they differed in safety. Most respondents prescribed 5-alpha reductase inhibitors based on the prostate size. CONCLUSION: These data provide a picture of current practices regarding the management of BPH in Korea. The diagnostic and treatment practices for BPH do not follow published guidelines. Our findings ask the question "How influential are international guidelines, and do they really affect patient management in countries that do not have country-specific guidelines?"

Estandarización de la terminología de la función del tracto urinario inferior: reporte del Subcomité de Estandarización de la International Continence Society (ICS) / The standardization of terminology of lower urinary tract function

Recientemente, la International Continence Society ha desarrollado una serie de reuniones que han dado como fruto, documentos de consenso sobre una serie de temas relevantes para los urólogos dedicados al estudio y tratamiento de las disfunciones del tracto urinario inferior. Estos documentos fijan conceptos y al mismo tiempo dan origen a una terminología estandarizada, que facilita el intercambio científico. Nos ha parecido de gran interés, traducir al español en esta oportunidad el documento The Standardization of Terminology of Lower Urinary Tract Function, trabajando en conjunto en varios países hispanoamericanos y en España, de modo de lograr una terminología uniforme también en nuestro idioma, que posibilite el intercambio en la región. Esperamos que esta iniciativa sea bien recibida por nuestros pares y que sea de real utilidad para el desarrollo de nuestra disciplina. Agradecemos muy especialmente al Dr. Paul Abrams, su ayuda para desarrollar esta iniciativa, del mismo modo que agradecemos a la International Continence Society, por autorizar a nuestro grupo para preparar esta traducción.
