Association of nerve-sparing grading in robotic radical prostatectomy and trifecta outcome.

PURPOSE: To evaluate the neurovascular bundle preservation grades during robotic-assisted radical prostatectomy and compared to the trifecta combined outcome (oncologic control, continence, and sexual function) twelve months after the surgery. METHODS: Cohort of patients who underwent nerve-sparing robotic-assisted radical prostatectomy had the neurovascular bundle preservation retrospectively graded from 0 to 8 according to the Hopkins subjective visual classification. Patients then were divided into two groups, according to the median of nerve-sparing grading: those with score six or high and those with score less than six. Main outcome was the trifecta combined outcome and secondary outcomes was the individual trifecta criteria (prospective analysis). A secondary analysis with groups divided according to pre-operatory SHIM score was made. RESULTS: One hundred robotic-assisted nerve-sparing radical prostatectomy were performed, of which 83 were included. There were 53 patients with grading greater than or equal to six (group 1) and 30 patients less than six (group 2). 66.6% patients (35/53) in group 1 had a trifecta combined outcome of compared to 33.3% (10/30) in group 2 (p = 0.017). Individually, the erectile function was higher in group 1 (73.6%) compared to group 2 (46.7%) (p = 0.014). Both the results of the combined endpoint trifecta and erection were also maintained in the group with preoperative SHIM ≥ 17. CONCLUSIONS: The grading of preservation of the neurovascular bundle in radical prostatectomy is related to a better combined trifecta outcome one year after surgery.

Burnout syndrome in pediatric urology: A perspective during the COVID-19 pandemic - Ibero-American survey.

INTRODUCTION: Burnout syndrome is a major cause of decreased life quality, mental health, and productivity for physicians. It is strongly related to work overload and has been a scarcely studied topic in pediatric urology. During the COVID-19 pandemic, authorities' recommendations have led to big changes in pediatric urology practice worldwide. This study aimed to evaluate the level of burnout in Ibero-American pediatric urologists (IPUs) during this pandemic. MATERIAL AND METHODS: A cross-sectional study was conducted by applying an electronic survey during the COVID-19 pandemic peak to members of the two major associations of pediatric urology in Ibero-America (the Ibero-American Society of Pediatric Urology [SIUP] and the Brazilian School of Pediatric Urology [BSPU]) to evaluate demographic, pre-pandemic, and pandemic data. Burnout levels were assessed using the Copenhagen Burnout Inventory (CBI) questionnaire. RESULTS: A response rate of 40% was obtained (182 out of 455 IPU respondents). Participants were from 14 different countries in Ibero-America and 75.4% were male. Data showed that during the pandemic there was a significant decrease in weekly workload, that is: > 40 h per week (h/w) (91.4%-44.6%, p < 0.001); and >6 h/w (94.9%-45.1%%, p < 0.001) in operating room time (ORT). Personal (Pe-BO), work-related (W-BO), and patient-related (Pa-BO) burnout levels among IPUs were 26.3%, 22.3%, and 7.4%, respectively (Summary table). An important difference by gender was seen, with women suffering more from the syndrome (odds ratio of 2.67 [95% confidence interval, 1.285.58; p = 0.013] for Pe-BO and OR of 3.26 [95% CI, 1.52-7.01; p = 0.004] for W-BO). CONCLUSION: A significant decrease in workload for IPU during the pandemic was observed, as well as a low level of burnout syndrome during this time. However, the predominance of burnout in women found in this study is notable.

Proposal of a New Electrode and Modality of Electrical Stimulation for Diaphragmatic Pacemakers.

PURPOSE: This report describes the implantation of a new design of intramuscular electrode to the diaphragm and introduces a new modality of electroventilation for diaphragmatic pacemaker. DESCRIPTION: We used 22 Large White female pigs to test 68 electrodes that were implanted in the abdominal portion of the diaphragm by videolaparoscopy. Animals were submitted to a new protocol of electroventilation with an unpolarized current and a single-channel mode with 1 electrode for each hemidiaphragm during 3 hours. EVALUATION: The electrodes were easily fixed to the diaphragm with the help of a deployment device designed for this purpose. There was no evidence of clinical complications such as pneumothorax or bleeding. No significant differences were observed in arterial blood gas analysis and serum lactate levels. CONCLUSIONS: The designed electrodes provided an excellent performance in connection between the electrical stimulator and the muscle tissue. The proposal for using an unpolarized current proved to be effective in stimulating both hemidiaphragms simultaneously with only a single channel of the electrical stimulator.
