The use of ADT in prostate cancer patients corresponded with a significant increase in cardiovascular morbidity associated with AMI and with nonfatal events. Therefore, ADT is linked to a significant negative impact on quality of life. Periodic cardiovascular evaluation is required for these patients.

Introduction:Renal ptosis is defined as the renal descent when there is a change from supine to orthostatic position, usually with a change of two vertebral bodies or more than five cm apart. Although rare, it is one of the causes of chronic flank pain or of upper abdomen. The typical patient of renal ptosis is young, female, thin, with complaint of pain when in an upright position (1, 2).Objective:Demonstrate a robot-assisted nephropexy technique in a young woman diagnosed with symptomatic renal ptosis on the right kidney, confirmed by imaging tests.Materials and Methods:A 29-year-old female patient with a history of chronic right-sided pain and palpable renal mobility on physical examination. The diagnosis of renal ptosis was confirmed by ultrasound imaging, excretory urography (Figure-1), and renal scintigraphy with 99mTc-DTPA (Figure-2). She was submitted to a robotic-assisted right nephropexy with a polypropylene mesh fixing the right kidney to the ipsilateral psoas muscle fascia.Result:We reported a 96-minute surgical time. The patient was discharged in the first postoperative day. At the one-month follow-up, there was an important improvement of the symptoms, with normality renal function and imaging tests describing adequate renal positioning.Conclusions:Robotic-assisted nephropexy is feasible and can be an excellent minimally invasive alternative technique for the proposed surgery. We reported a shorter hospital stay and a faster postoperative recovery compared with the opened procedure.

Purpose Bladder cancer is the ninth most frequent cancer worldwide with the twelfth highest incidence. However, its treatment has financial impacts that directly affect health burden. There is a scarcity of data about the costs related to healthcare in Brazil, especially in the public setting. As previously demonstrated, despite not being one of the most frequent cancers, bladder cancer appears to be one of the most expensive. The present study aimed to assess the costs related to the treatment of bladder cancer in the public setting in Brazil. Patients and Methods Retrospective data of patients treated for urothelial bladder carcinoma from 2019 to 2020 were retrieved at a single center. All charts were reviewed, with the assessment of clinical data, exams, surgical data, and postprocedure outcomes. The hospital finance department calculated the costs for outpatient evaluation, inpatient procedures, complementary exams, materials, drugs, and professionals' fees throughout all operations. Results A total of 107 patients with bladder cancer were analyzed, representing a total expenditure of BRL 5,671,042.70 and a mean cost of BRL 53,000.04 per patient (US$1.00 = BRL 5.60). Median costs were progressively higher for patients with stages I, II, III, and IV. Patients who underwent radical cystectomy (n = 14) had a median treatment cost of BRL 136,606.25 ± 96,059.08, during a mean follow-up of 9.2 months. Hospitalization costs represented 25% (range 20-43% according to the stage) of all expenditure. Medications and medical supplies represented 18% (16-23% according to the stage) of expenditure. Medical fees represented 31% of costs for stage I disease, but only 4% in stage II, III, and IV. Costs associated with emergency room visits were only observed in stage III and IV disease, representing 1% of all expenditure. Conclusions The management of bladder cancer resulted in a significant economic burden on our public health system. The costs associated with stage I bladder cancer were 4-12 times higher than those related to the treatment of other common malignancies at initial stages. Treatment was also expensive during the first months with more advanced stages.

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. The present study examined the association between HER2 expression and the histologic features of PCa subjected to radical prostatectomy (RP) and evaluated the role of testosterone suppression in HER2 expression. In group 1, specimens from individuals who underwent RP without prior neoadjuvant androgen deprivation therapy (ADT) were included (n=42). In group 2 (PCa with ADT), specimens from individuals who underwent RP and received neoadjuvant cyproterone acetate during distinct periods (200 mg daily for 1-24 months) were included (n=150; cohort derived from a previous study). Immunohistochemical expression of HER2 was associated with prognostic factors such as perineural invasion, extra-prostatic disease, T stage, serum prostate-specific antigen (PSA), angiolymphatic invasion and surgical margins. Univariate regression analysis indicated that perineural invasion, PSA, International Society of Urological Pathology, angiolymphatic invasion, margin, T stage and neoadjuvant ADT was associated with HER2 expression. Ordinal regression analysis indicated a significant effect of neoadjuvant ADT alone on HER2 expression (P<0.001). In addition, regression analysis indicated a significant effect of neoadjuvant ADT alone on HER2 expression (odd ratio=0.01; 95% CI, 0.00, 0.02; P<0.001). HER2 was expressed in PCa samples but was not associated with known prognostic factors. The use of short-acting ADT and the consequent blockage of testosterone effect may suppress the expression of HER2 in PCa cells.

Muscle-invasive bladder cancer (MIBC) is an aggressive disease with a complex treatment. In Brazil, as in most developing countries, data are scarce, but mortality seems exceedingly high. We have created a centralized program involving a multidisciplinary clinic in a region comprising 7 municipalities. Helping patients with adequate performance status get the right treatment helped to reduce 90-day mortality after radical cystectomy from 37% to 1.9%.

Background: The three-way indwelling urinary catheter (IUC) is used for continuous bladder irrigation and is considered the cornerstone for clinical treatment of patients with macroscopic hematuria. Although there seems to be a logical relationship between catheter size and efficacy of irrigation and drainage, we often observe relevant variations in these parameters between different brands of catheters available on the market. The aim of this study was to compare the mechanical properties of different models of latex and silicone three-way catheters in an in vitro setting that resembles clinical use. Methods: Three different three-way catheters were evaluated: Gold Silicone-Coated Rusch® (Model A), 100% Silicone Rusch® (Model B) and X-Flow Coloplast® (Model C). Irrigation channel, drainage channel, and overall cross-sectional areas were all digitally measured. Irrigation and drainage channel flow rates were measured and correlated with their corresponding catheter cross-sectional area values. Results: Different catheter models of the same caliber have different internal irrigation port diameters, internal drainage port diameters and internal cuff port diameters. The Model C IUC internal irrigation port diameter is significantly larger than models A and B. When flows were evaluated, we found that in the same model, the increase in caliber of the IUC was related to an increased drainage flow, but not to an increased irrigation flow. Conclusion: Precise measurements of the internal architecture of the three-way catheter, rather than relying on the caliber itself, could assist surgeons in choosing the best product for each specific patient, while minimizing complications.
