Nephrometry scoring systems: their importance for the planning of nephron-sparing surgery and the relationships among them / Escores nefrométricos: sua importância para o planejamento da nefrectomia parcial e as relações entre eles

Abstract In recent years, the development of new imaging techniques and scoring systems have improved the diagnosis and management of small renal masses. Imaging-based nephrometry scoring systems play an interesting role in the planning of nephron-sparing surgery, providing surgeons with the information necessary to determine the complexity of the renal mass, to deliver the appropriate postoperative care, and to predict adverse outcomes. The aim of this study was to review nephrometry scoring systems, evaluating their characteristics and the relationships among them. The urology and radiology communities should decide which nephrometry scoring system will prevail and be used in daily practice.

Resumo O diagnóstico e o manejo das pequenas massas renais têm sido aprimorados nos últimos anos com o desenvolvimento de técnicas de imagem e escores que desempenham papel interessante no planejamento da nefrectomia parcial, fornecendo informações importantes ao cirurgião para determinar o tipo de tratamento em relação a complexidade da massa renal, cuidados pós-operatórios e previsão de complicações após as cirurgias. O objetivo deste estudo é revisar os escores de nefrometria, suas características e relações entre eles no cenário da cirurgia. Os serviços de urologia e radiologia devem decidir qual é o melhor escore de nefrometria para ser utilizado na prática diária.

Practical evaluation of the R.E.N.A.L. score system in 150 laparoscopic nephron sparing surgeries

ABSTRACT Introduction: Nephrometric scores play an interesting role in nephron sparring surgery (NSS) planning. The aim of this study is to evaluate if R.E.N.A.L. score (RS) is capable to predict the occurrence of adverse events in laparoscopic NSS. Materials and Methods: We prospectively studied 150 laparoscopic NSS between 2015 and 2018 to evaluate the relationship between RS and incidence of adverse events. Clavien 3 or superior complications, warm ischemia time (WIT) over 30 minutes, tumor violation, positive surgical margins (PSM) and necessity of amplification of renal parenchyma during the resection of the masses to obtain free margins were considered as adverse events. We compared each item of the RS isolated and divided the patients between low risk and high risk. Results: Adverse results occurred in 48 cases (32%). Amplification of the margin of resection was observed in 28 cases (19%). WIT exceeded 30 minutes in 9 cases (6.1%), complications Clavien 3 or superior occurred in 13 cases (9%) and PSM were detected en 6 cases (4%). Comparing the patients with adverse outcomes and each item of the RS we did not find any statistical difference, but when divided into high risk and low risk, we found that patients in the high risk group had a higher tendency to present ad-verse results - 25.84% vs. 44.26% (p=0.03). Conclusions: RS system is a good way to predict adverse outcomes in NSS, especially in cases over 7. Further studies should focus on robotic approach and patient's characteristics other than the masses' aspects.

Tratamento manipulativo osteopático musculoesquelético em mulheres com incontinência urinária não complicada / Musculoskeletal osteopathic manipulative treatment in women with uncomplicated urinary incontinence

Controle eficiente dos mecanismos de fechamento uretral é essencial para continência urinária feminina, envolvendo mecanismo similar ao necessário para estabilidade sacroilíaca. Estudos demonstraram benefícios na reabilitação funcional do assoalho pélvico, após tratamento de pacientes com lombalgia, utilizando técnicas de manipulação osteopática. O objetivo primário deste estudo foi avaliar melhora da incontinência urinária após tratamento manipulativo osteopático musculoesquelético (TMO), associado com fisioterapia pélvica (FP). Participaram pacientes da divisão de fisioterapia da Policlínica Piquet Carneiro/UERJ, com diagnóstico de incontinência urinária não complicada, idade entre 21 e 65 anos, que responderam os questionários: International Consultation on Incontinence Questionnaire - Short Form - ICIQ, Stress Urinary Incontinance Questionnaire - SUIQ, Overactive Bladder Questionnaire - ICIQ-OAB qol, e o questionário de qualidade de vida e saúde geral ­ EQ5D. A força perineal foi avaliada através do teste de avaliação funcional do assoalho pélvico, e as pacientes foram divididas em dois grupos: no grupo FP submetidas ao protocolo de FP por 10 semanas, e no grupo TMO submetidas ao mesmo protocolo, associado com TMO, pelo mesmo período. No presente estudo, a utilização do TMO associado à FP obteve resultados semelhantes à utilização de FP isoladamente, não acrescentando melhora na resposta ao tratamento da incontinência urinária não complicada.

Effective control of urethral closure mechanisms is essential for female urinary continence, involving mechanism similar to that required for sacroiliac stability. Studies have demonstrated benefits in the functional rehabilitation of the pelvic floor, after treatment of patients with low back pain, using osteopathic manipulation techniques. Primary objective of this study was to evaluate the improvement of urinary incontinence after musculoskeletal manipulation (OMT), associated with pelvic physiotherapy (PF). Patients from the Physiotherapy Division of the Policlínica Piquet Carneiro/UERJ, diagnosed with uncomplicated urinary incontinence, aged between 21 and 65 years, answered the questionnaires: International Consultation on Incontinence Questionnaire - Short Form - ICIQ, Stress Urinary Incontinence Questionnaire - SUIQ, Overactive Bladder Questionnaire - ICIQ-OAB qol, and the quality of life and general health questionnaire - EQ5D. The perineal force was evaluated through functional evaluation of the pelvic floor. Patients were divided: in the FP group submitted to the FP protocol, and in the OMT group submitted to the same protocol, associated with OMT, for 10 weeks. In the present study the use of OMT associated with PF, obtained results similar to the use of PF alone, and did not add improvement in the response to treatment of uncomplicated urinary incontinence.

Parameters of two-dimensional perineal ultrasonography for evaluation of urinary incontinence after Radical Prostatectomy

Introduction Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. Materials and Methods This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP) for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D) perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. Results Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002). We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008). Conclusions We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared. .

Efficacy and safety of parecoxib in the treatment of acute renal colic: a randomized clinical trial

PURPOSE: Although nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs) and opioids are effective treatments for acute renal colic, they are associated with adverse events (AEs). As cyclooxygenase-2 selective NSAIDs may provide a safer alternative, we compared the efficacy and safety of parecoxib versus an nsNSAID in subjects with acute renal colic. MATERIALS AND METHODS: Phase IV., multicenter, double-blind, noninferiority, active-controlled study: 338 subjects with acute renal colic were randomized to parecoxib 40 mg i.v. plus placebo (n = 174) or ketoprofen 100 mg IV plus placebo (n = 164). 338 subjects with acute renal colic were randomized to parecoxib 40 mg IV (n = 174) or ketoprofen 100 mg IV(n = 164) plus placebo. Subjects were evaluated 15, 30, 45, 60, 90 and 120 minutes after treatment start and 24 hours after discharge. Primary endpoint was the mean pain intensity difference (PID) at 30 minutes by visual analog scale (VAS) (per-protocol population). An ANCOVA model was used with treatment group, country, and baseline score as covariates. Non-inferiority of parecoxib to ketoprofen was declared if the lower bound of the 95 percent confidence interval (CI) for the difference between the two groups excluded the pre-established margin of 10 mm for the primary endpoint. RESULTS: Baseline demographics were similar. The mean (SD) mPID30 min was 33.84 (24.61) and 35.16 (26.01) for parecoxib and ketoprofen, respectively. For treatment difference (parecoxib-ketoprofen) the lower bound of the 95 percent CI was 6.53. The mean change from baseline in VAS 30 minutes after study medication was ~43 mm; AEs were comparable between treatments. CONCLUSIONS: Parecoxib is as effective as ketoprofen in the treatment of pain due to acute renal colic, is well tolerated, and has a comparable safety profile.

Comparative study between trimetazidine and ice slush hypothermia in protection against renal ischemia/reperfusion injury in a porcine model

PURPOSE: The aim of the study was to compare the effects of renal ice slush hypothermia and the use of trimetazidine in the protection against ischemia/reperfusion (I/R) injury. MATERIALS AND METHODS: Fifteen farm pigs were submitted to left kidney ischemia and right nephrectomy during the same procedure. Animals were divided into three groups. Group 1 was submitted to warm ischemia; Group 2 was submitted to cold ischemia with ice slush; and Group 3 received trimetazidine 20 mg one day and 4 hours before surgery. Ischemia time was 120 minutes in all three groups. Serum creatinine (SCr) and plasma iohexol clearance (CLioh) were measured before surgery and on postoperative days (PODs) 1,3,7, and 14. Semi-quantitative analyses of histological alterations were performed by a pathologist. A p value of < 0.05 was considered significant. RESULTS: All groups showed elevation of serum creatinine in the first week. Serum creatinine was higher in Group 3 in the first and third postoperative days (Mean Cr: 5.5 and 8.1 respectively). Group 2 showed a lower increase in creatinine and a lower decrease in iohexol clearance than the others. Renal function stabilized in the fourteenth POD in all three groups. Analyses of histological alterations did not reach statistical significance between groups. CONCLUSION: Trimetazidine did not show protection against renal I/R injury in comparison to warm ischemia or hypothermia in a porcine model submitted to 120 minutes of renal ischemia.

Avaliação da violência intradomiciliar na criança e no adolescente enuréticos / Assessment of domestic violence against children and adolescents with enuresis

OBJETIVO: Descrever a frequência da violência doméstica praticada contra crianças e adolescentes brasileiros devido ao episódio enurético e os fatores de risco associados a ela. MÉTODOS: Foi realizado um estudo transversal envolvendo 149 pacientes com idades de entre 6 e 18 anos, diagnosticados com enurese noturna monossintomática primária. Durante uma entrevista semiestruturada com o paciente e seu responsável legal, foram obtidas informações sobre as características da violência doméstica e o agressor, sendo adicionada uma atividade lúdica para o paciente. A agressão foi classificada em verbal, física sem contato, ou física com contato. RESULTADOS: Dos pacientes entrevistados, 89 por cento (n = 132) sofreram algum tipo de agressão devido ao episódio enurético. Todos os casos apresentaram punição verbal associada ou não a outro tipo de agressão. Punição física sem contato ocorreu em 50,8 por cento dos casos, e com contato, em 48,5 por cento. O principal agressor foi a mãe (87,9 por cento). Em um caso, houve lesão genital grave que necessitou de cirurgia reconstrutora. Houve uma correlação significativa (p = 0,043, r = -0,768) entre os anos de estudo dos responsáveis e a gravidade da punição. CONCLUSÕES: Os índices de punição em pacientes com enurese noturna monossintomática primária são alarmantes. Crianças e adolescentes enuréticos que convivem no âmbito doméstico com pessoas com poucos anos de estudo podem ser considerados população de risco em relação à violência doméstica.

OBJECTIVE: To describe the frequency of domestic violence against Brazilian children and adolescents due to episodes of enuresis, as well as associated risk factors. METHODS: A cross-sectional study was carried out with 149 patients aged between 6 and 18 years who received the diagnosis of primary monosymptomatic nocturnal enuresis. A semi-structured interview was done with the patients and their guardians to collect information about the characteristics of domestic violence and abusers. In addition, a playful activity was performed by the patients. Abuse was characterized as verbal aggression, physical aggression without physical contact, and physical aggression with physical contact. RESULTS: Eighty-nine percent (n = 132) of the patients suffered abuse due to episodes of urine leakage. All cases were characterized by verbal punishment associated or not with other types of aggression. Physical punishment without physical contact occurred in 50.8 percent of the cases, while physical punishment with physical contact accounted for 48.5 percent of the cases. The main abuser was the mother (87.9 percent). One patient suffered an intentional severe genital injury, and reconstructive surgery was necessary. There was a significant correlation (p = 0.043, r = -0.768) between the abuser's educational level and punishment severity. CONCLUSIONS: Punishment rates due to episodes of urine leakage are alarming. Children and adolescents with enuresis who live with low-educated people can be considered a population at risk of suffering domestic violence.

Avaliação das medidas do comprimento peniano de crianças e adolescentes / Penile anthropometry in Brazilian child and adolescent

OBJETIVO: Classicamente, o pênis tem duas funções: permitir a fertilização interna e direcionar o jato miccional. Entretanto, alterações objetivas do tamanho peniano podem levar ao diagnóstico de doenças. Além disso, é motivo comum de consulta médica a busca por parâmetros de normalidade do tamanho do pênis. Contudo, a antropometria do pênis da criança e do adolescente brasileiros ainda não foi devidamente estudada. O objetivo do estudo é realizar a antropometria do pênis de crianças e adolescentes brasileiros, estabelecendo referências para aplicação clínica. MÉTODOS: Foi realizado um estudo transversal, envolvendo 2.010 pacientes com idades variando entre 0 e 18 anos. Foram obtidas cinco medidas penianas: diâmetro da haste peniana; comprimento aparente e real do pênis flácido; comprimento aparente e real (CRTmax) do pênis flácido sob tração máxima. O desenvolvimento puberal foi caracterizado pelos critérios de Tanner. RESULTADOS: De todas as medidas penianas, o CRTmax foi a única que não apresentou variação significativa interpesquisador em todas as faixas etárias analisadas (p = 0,255). Os resultados foram distribuídos em tabelas com a média do CRTmax e os valores do que se considera micropênis (média - 2,5 desvio padrão) de acordo com as diferentes faixas etárias e com os diferentes graus de maturação sexual de Tanner. Foi desenvolvido um gráfico com a distribuição dos valores do CRTmax distribuído por percentis 10, 25, 50, 75 e 90 por faixa etária. CONCLUSÕES: De todas as medidas antropométricas penianas, o CRTmax é a única clinicamente útil. Recomendamos nossos resultados como referência de antropometria peniana para crianças e adolescentes brasileiros.

OBJECTIVE: Classically, the penis has two functions: to make internal fertilization possible and to direct the urine stream. However, objective abnormalities in penis size can lead to diseases being diagnosed. Furthermore, many medical consultations are the result of patients seeking parameters for normal penis size. Additionally, the penile anthropometry of Brazilian children and adolescents has not yet been properly studied. The objective of this study is to carry out penile anthropometry of Brazilian children and adolescents, establishing references for clinical use. METHODS: A cross-sectional study was carried out of 2,010 patients with ages varying from 0 to 18 years. Five penile measurements were taken: diameter of penile shaft; apparent and real length of flaccid penis; apparent and real (RSLmax) length of flaccid penis fully stretched. Pubertal development was defined according to Tanner's criteria. RESULTS: Only RSLmax, out of all of the penile measurements, did not exhibit significant interobserver variation at all ages analyzed (p = 0.255). Results were tabulated with mean RSLmax and the values that define micropenis (mean - 2.5 standard deviations) by age and by Tanner sexual maturity stages. A graph was plotted of the distribution of RSLmax results by the 10th, 25th, 50th, 75th and 90th percentiles and by age. CONCLUSIONS: Out of all of the penile anthropometric measurements, only RSLmax is clinically useful. We recommend our results as a reference standard for penile anthropometry of Brazilian children and adolescents.

Avaliaçäo multicêntrica da eficácia e tolerabilidade do extrato lipidoesterólico de Serenoa repens em pacientes com hiperplasia prostática benigna sintomática / Efficacy and tolerability of the extract of Serenoa repens in a multicentric study in patients with symptomatic Benign Prostatic Hyperplasia

Objetivo: investigar a eficácia e a tolerabilidade do extrato lipoesterólico de Serenoa repens (LSESr) no tratamento da Hiperplasia Prostática Benigna (HPB). Métodos: estudo multicêntrico prospectivo, aberto, näo-controlado, realizado em 17 clínicas urológicas. Estudados 142 pacientes ambulatoriais com idade acima dos 50 anos e HPB sintomática, Pontuaçäo Internacional de Sintomas Prostáticos (I-PSS) maior ou igual a 8 na escala da OMS e taxa máxima de fluxo urinário menor ou igual a 12 ml/s para um volume urinário maior ou igual a 150 ml. Os pacientes receberam uma capsula de 160 mg do extrato lipidoesterólico de Serenoa repens duas vezes ao dia durante três meses. Avaliados I_PSS, índice de qualidade de vida (QV), urofluxometria e dosagem do antígeno prostático específico (PSA) sérico no início e ao término do estudo. Os efeitos colaterais foram registrados sistematicamente. A análise estatística foi realizada, utilizando-se um teste "t" pareado para avaliar a evoluçäo do I-PSS e da urofluxometria em D90 comparado ao D0. Obsevadas alteraçöes significativas nos parâmetros, nenhuma reaçäo adversa séria foi observada, outras reaçöes adversas leves e passageiras foram registradas em 10,56 porcento dos casos, principalmente gastrointestinais. Somente um paciente abandonou o tratamento devido à reaçäo adversa gastrointestinal. Näo houve diferença estatísticamente significante entre a média basal e final dos valores do PSA. Neste estudo o extrato lipidoesterólico da Serenoa repens demonstrou ser uma terapia medicamentosa da HPB com boa eficácia na sintomatologia e nas aferiçöes objetivas, além de ter sido muito bem tolerado pela grande maioria dos pacientes.(au)

Aspectos práticos do tratamento do carcinoma localizado da próstata (T1/T2 ou A/B) / Localized prostate cancer: practical aspects of treatment (T10-T2 ou A/B)

The detection rates of localized prostate cancer have increased sifnificantly in recent years because of the routine prostate examination and PSA dosage. In this stage the perspective of cure or at least disease control is expected. There are two potential curative treatments for clinically localized prostate cancer: radical prostatectomy and radiation therapy. For patients with life expectancy greater than 10 years and in good health status the surgical treatment, according to the majority of authors, seems to have more significant therapeutic benefits. It is important to point out that both the radiation sensitive and radiation resistant cell populations can be completely excised. Potential harm includes urinary incontinence and erectile dysfunction. On the other hand, for patients without those characteristics or who decline surgical approach, radiotherapy is recommended. The main drawback of this technique is that approximately 30 percent of clinically localized tumors countain cell clones that cannot be eradicated with therapeutic doses or radiation. Such patients have been documented to have a high incidence of subsequent distant metastases and persistently rising serum PSA levels. Interstitial radiation therapy has some attractive features, such as avoiding major surgery and the low rates of impotence and incontinence. Nevertheless, is not routinely applied because of the radiation resistent cell clones and the uneven distribution of radiation thet yields poor treatment results. With the newer branchytherapy techniques, long-term results are lacking. The potential harm or radiation includes cystitis, proctitis and erectile dysfunction...
