Complications and adverse events in lymphadenectomy of the inguinal area: worldwide expert consensus.

Background: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes.

Mesentery-Sparing Technique: a New Intracorporeal Approach for Urinary Diversion in Robot-Assisted Radical Cystectomy.

Background: Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is associated with significant morbidity and mortality. We present an alternative technique that preserves the complete mesenteric vascularization during the isolation of the intestinal segment used in ICUD, including distal vessels. This approach aims to minimize the risk of ischemia in both the ileal anastomosis and the isolated loop at the diversion site.

Neoadjuvant platinum-based chemotherapy and lymphadenectomy for penile cancer: an international, multi-institutional, real-world study.

Introduction: This study investigated the efficacy and safety of neoadjuvant chemotherapy for locally advance penile squamous cell carcinoma for which current evidence is lacking.

Methods: Included patients had locally advanced penile squamous cell carcinoma with clinical lymph node metastasis treated with at least 1 dose of neoadjuvant chemotherapy prior to planned consolidative lymphadenectomy. Objective response rates were assessed using Response Evaluation Criteria in Solid Tumors v1.

Patient's safety and satisfaction on same day discharge after robotic and laparoscopic radical prostatectomy versus discharge after 24 or 48 h: a longitudinal randomized prospective study.

Background: There is a tendency of prompted global health systems to reduce the length of hospital stay without compromising patient safety or satisfaction. We evaluated the safety and viability of early discharge in patients undergoing minimally invasive radical prostatectomy (MIRP), as well as patient satisfaction with this strategy.

Methods: This longitudinal prospective study included 72 patients who underwent MIRP for prostate cancer.

Ergonomic risk assessment of surgeon's position during radical prostatectomy: Laparoscopic versus robotic approach.

Background And Objectives: Radical prostatectomy (RP) is a definitive surgical therapy for localized prostate cancer. Evidence suggests that the poor ergonomics of surgeons during RP may lead to work-related musculoskeletal disorders and loss of productivity. Since each surgery modality has its physical demands, we compared the ergonomic risk between laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy.

Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer.

PD1.5 variant on gene, regulator of T lymphocyte activity, influences non-muscle-invasive bladder cancer risk.

Background: Since failure in recognition of abnormal cells by the immune system has an important role in bladder cancer development and progression, this study aimed to evaluate whether PD1 (c.627+252C>T) and PD1.5 (c.

Cost-Effectiveness Analysis of Robotic-Assisted Radical Prostatectomy for Localized Prostate Cancer From the Brazilian Public System Perspective.

Objectives: Radical prostatectomy (RP) is the gold standard for the surgical treatment of localized prostate cancer, presenting better results than radiotherapy especially for high-risk patients. Although it has clinical and technical benefits compared with open and laparoscopic techniques, the robotic-assisted RP is not publicly funded in Brazil. The objective of this study was to calculate the cost-effectiveness of the robotic-assisted RP from the Brazilian public system perspective.

The influence of testosterone suppression on HER2 immunoexpression in prostatic neoplastic tissue.

During initial risk assessments, the metastatic potential of prostate cancer (PCa) may not be fully considered. The tumor's multicentric origin, which is associated with genetic mutations, may explain existing treatment limitations. Investigating human epidermal growth factor receptor 2 (HER2) expression in patients with different stages of PCa may therefore increase understanding of the mechanisms associated with the development of castration resistance.

Salvage Retzius sparing robotic assisted radical prostatectomy: the first brazilian experience.

Introduction:: Salvage Radical Prostatectomy after radiation therapy is challenging and associated with high rates of serious complications (1, 2). The novel Retzius-Sparing RARP (RS-RARP) approach has shown excellent continence outcomes (3, 4).

Purpose:: To describe step-by-step our Salvage Retzius-Sparing RARP (sRS-RARP) operative technique and report feasibility, safety and the preliminary oncological and continence outcomes in the post-radiation scenario.

Prognostic Factors in De Novo Metastatic Renal Cell Carcinoma: A Report From the Latin American Renal Cancer Group.

Purpose: To assess the effect of clinical and pathological variables on cancer-specific and overall survival (OS) in de novo metastatic patients from a collaborative of primarily Latin American countries.

Patients And Methods: Of 4,060 patients with renal cell carcinoma diagnosed between 1990 and 2015, a total of 530 (14.5%) had metastasis at clinical presentation.

Comparative study between minimally invasive supraorbital craniotomy and pterional craniotomy for treating anterior circulation cerebral aneurysms in a low-resource setting.

The challenges encountered in performing minimally invasive approaches, such as supraorbital minicraniotomy (SOMC), in services without adequate equipment are rarely reported in the literature. This study analyzes the viability of SOMC in the treatment of cerebral aneurysms, using exactly the same resources as pterional craniotomy (PC). The results of these two techniques are compared.

Penile cancer.

Penile squamous cell carcinoma (PSCC) is a rare cancer with orphan disease designation and a prevalence of 0.1-1 per 100,000 men in high-income countries, but it constitutes up to 10% of malignancies in men in some African, Asian and South American regions. Risk factors for PSCC include the absence of childhood circumcision, phimosis, chronic inflammation, poor penile hygiene, smoking, immunosuppression and infection with human papillomavirus (HPV).

Recommendations on robotic-assisted radical prostatectomy: a Brazilian experts' consensus.

Radical prostatectomy is a commonly adopted treatment for localized/locally advanced prostate cancer in men with a life expectancy of ten years or more. Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure.

Robotic parastomal hernia repair.

Introduction And Objective:: Annually, more than one hundred thousand new stomas are created in the United States and near 30-50% of those will develop parastomal hernia ( 1 ). Occasionally parastomal hernias may result in life threatening complications such as bowel obstruction or strangulation requiring urgent surgical intervention ( 2 ). The minimally invasive surgery for these hernias are preferred, specially when the primary case was either laparoscopic or robot-assisted.

Laparoscopic Treatment of Ureteral Endometriosis: A Systematic Review.

Objective: To review the literature for the preoperative clinical characteristics, surgical findings, and outcomes of patients who underwent laparoscopic surgical treatment of ureteral endometriosis (UE).

Data Sources: A systematic search was performed in the PubMed and Scopus databases.

Methods Of Study Selection: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, studies in English language that assessed UE treated surgically by laparoscopy published between 2008 and 2020 were selected.

Role of salvage lymph node dissection in patients previously treated for prostate cancer: systematic review.

Prostate cancer is the most common invasive cancer in men. Radical prostatectomy (RP) is a definitive treatment option, but biochemical recurrence can reach 40%. Salvage lymphadenectomy is a relatively recent approach to oligometasis and has been rapidly diffused primarily due to improvement in imaging diagnosis and results showing possibly promising therapy.

Characteristics and Surgical Outcomes in Very Elderly Patients (≥75 years) with Renal Cell Carcinoma: Data from the Latin American Renal Cancer Group.

Background: The incidence of renal cell carcinoma (RCC) is increasing globally due to an aging population and widespread use of imaging studies.

Objective: The aim of this study was to describe the characteristics and perioperative outcomes of RCC surgery in very elderly patients (VEP), ≥ 75 years of age.

Methods: This is a retrospective comparative study of 3656 patients who underwent the treatment for RCC from 1990 to 2015 in 28 centers from eight Latin American countries.

Videoendoscopic gracilis muscle flap (VEGMF): A new minimally invasive technique for rectovesical fistula closure.

Fistulas between the rectum and the bladder have different etiologies, they may be congenital, acquired, or iatrogenic. Symptoms such as pneumaturia, fecaluria, and the passage of urine through the rectum are often alleviated by fecal and urinary diversion. The interposition of a flap of gracilis muscle is a technique that is very successful, but the conventional dissection of this flap involves a very large incision and a worse aesthetic result

Small renal masses in Latin-American population: characteristics and prognostic factors for survival, recurrence and metastasis - a multi-institutional study from LARCG database.

Background: To evaluate demographic, clinical and pathological characteristics of small renal masses (SRM) (≤ 4 cm) in a Latin-American population provided by LARCG (Latin-American Renal Cancer Group) and analyze predictors of survival, recurrence and metastasis.

Methods: A multi-institutional retrospective cohort study of 1523 patients submitted to surgical treatment for non-metastatic SRM from 1979 to 2016. Comparisons between radical (RN) or partial nephrectomy (PN) and young or elderly patients were performed.

Do rapid emotional thermometers correlate with multidimensional validated structured questionnaires in low-risk prostate cancer?

Purpose: To promptly identify mental suffering in low-risk prostate cancer (LRPC) patients, vulnerable to over- and undertreatment, we evaluated the correlation of rapid emotional thermometers (ET) with multidimensional validated structured questionnaires.

Methods: At diagnosis, consecutive LRPC patients underwent five ET domains: emotional suffering, anxiety, depression (DT), revolt and need for help and multidimensional questionnaires: beck anxiety inventory (BAI), beck depression inventory (BDI), beck hopelessness scale, SF36 (physical functioning PF, role limitations due to physical health RP, bodily pain BP, general health perceptions GH, vitality VT, social functioning SF, role limitations due to emotional problems RE and general mental health MH), international index of erectile function and international prostate symptom score (IPSS).

Results: Among 30 included patients, mean age 67.

Robot-assisted transvesical partial cystectomy for leiomyoma of bladder trigone.

Introduction And Objective: Leiomyomas of the urinary bladder are very rare neoplasms and are the most common benign mesenchymal tumors of the bladder, accounting for 35% of these. Treatment of leiomyomas is mainly surgical and approaches range from transurethral resection to open segmental resection or laparoscopic partial cystectomy. We sought to present the surgical technique of robot-assisted transvesical partial cystectomy for bladder leiomyoma.

Short-Term Surgical Outcomes of Standard and Lateral Video Endoscopic Inguinal Lymphadenectomy: A Multinational Retrospective Study.

Video endoscopic inguinal lymphadenectomy (VEIL) is a minimally invasive technique that gives superior surgical outcomes than open inguinal lymphadenectomy (IL) for treating lymph node metastasis in penile, vulvar, and skin cancers. This study compared surgical outcomes obtained with two different approaches of VEIL, standard VEIL and lateral VEIL (L-VEIL), in cancer patients. Sixty-two patients who underwent standard VEIL ( = 15) or L-VEIL ( = 47) for treatment of lymph node metastasis were evaluated retrospectively from three centers in Brazil, Egypt, and India.
