ABSTRACT

ABSTRACT Purpose: False-negative urodynamic findings may mislead or prevent planned treatments due to unmatched findings with the clinical presentation. We hypothesized that the absence of urodynamic demonstration of SUI or OAB on urodynamics would interfere with clinical outcomes. Materials and Methods: Materials and Methods: We prospectively studied 124 women with (94) or without (30) demonstrable SUI after sling operations. Similarly, 64 women with OAB syndrome with (38) or without (26) demonstrable DO were also compared after treatment with anticholinergic agents. Patients were assessed with the UDI-6 and IIQ-7 questionnaires 3 and 6 months after treatment. Results: Only 76% of SUI patients demonstrated urine leakage during urodynamics. The UDI-6 score was higher in the demonstrable-SUI and demonstrable-DO groups, while the IIQ-7 score was comparable within the incontinence or urgency/frequency groups. Demonstrable and non-demonstrable SUI-operated patients showed similar outcomes. Patients with urgency syndromes with or without demonstrable DO had a similar rate of improvement with anticholinergic therapy. Conclusions: Women with clinical complaints of SUI objectively demonstrated on urodynamics presented the same subjective clinical outcome as those with SUI lacking objective demonstration when measured by the UDI-6 and IIQ-7 questionnaires. Similarly, patients with OAB syndrome with or without demonstrable DO had similar clinical improvement when treated with anticholinergics and measured using the same questionnaires.

ABSTRACT

Abstract Objectives To understand the clinical relationship between lower limbs functions and the recovery of spontaneous voiding after an acute urinary retention (AUR) in older patients admitted to hospitals for non-urological causes using clinical parameters. Materials and Methods 56 adult patients (32 men; mean age: 77.9 ± 8.3 and 24 women; mean age 82.1 ± 4.6) with AUR were prospectively followed with validated Physical Performance Mobility Exam (PPME) instrument to evaluate the relationship between the recovery of mobility capacity and spontaneous voiding. After a short period of permanent bladder drainage patients started CIC along evaluation by PPME during hospitalization and at 7, 15, 30 60, 90, and 180 days of discharge. Mann-Whitney U, chi-square test and ANOVA tests were used. Results All patients were hospitalized for at least 15 days (Median 26.3 ± 4.1 days). Progressive improvement on mobility scale measured by PPME was observed after leaving ICU and along the initial 7 days of hospitalization but with a deterioration if hospitalization extends beyond 15 days (p<0.03). Prolonged hospital stay impairs mobility in all domains (p<0.05) except step-up and transfer skills (p<0.02) although a recovery rate on spontaneous voiding persistented. Restoration of spontaneous voiding was accompanied by improvement on mobility scale (p<0.02). Recovery of spontaneous voiding was markedly observed after discharging the hospital. All patients recovered spontaneous voiding until 6 months of follow-up. Conclusions Recovery to spontaneous voiding after acute urinary retention in the hospital setting may be anticipated by evaluation of lower limbs function measured by validated instruments.

ABSTRACT

Objectives Determine what happens to patients after unsuccessful SUI operations and to explore the reasons why these patients change doctors. Materials and Methods One hundred consecutive failed patients treated for SUI were interviewed about the exams requested after persistence of the incontinence as well as the reasons they abandoned their primary doctors through a structured questionnaire. Results Among the patients with cases of anterior colporrhaphy, bladder suspensions or slings, 34.3%, 13.7% and 8.3%, respectively, were not offered any further type of investigative procedures to clarify the failure. Urodynamic evaluations were recommended in 75% of failed slings, and 66.6% of the patients proceeded with these tests. In contrast, only 31% of patients with bladder suspensions and 40% of patients with anterior colporrhaphy were recommended for urodynamic investigations, and only 44.4% and 28.5% of them, respectively, proceeded with the option. Patients´ delusions were reinforced by the doctors’ attitude toward the investigations. Vacuous justifications and the lack of intention to seek improvement were the driving forces causing the patients to change doctors. Conclusion Unsuccessful patients are evaluated in a non-protocol form. Difficulty in clarifying the reasons for surgical failure and the disruption of the doctor-patient relationship are the main reasons why patients abandon them. .

ABSTRACT

INTRODUCTION: Bladder sarcomatoid carcinoma is a very rare variant of transitional cell carcinoma. With disputed nomenclature, the tumor has been described previously under a variety of names such as sarcomatoid carcinoma, pseudosarcoma, malignant mixed mesodermal/Müllerian tumor, metaplastic carcinoma and spindle cell carcinoma. This malignancy represents 0.3 percent of all bladder tumors and has an aggressive behavior yielding a poor prognosis despite radio and chemotherapy. CASE REPORT: An 81 y/o man presented with a transitional cell carcinoma and underwent a transurethral resection. Adjuvant onco-BCG was introduced. After 9 months of follow-up, a local tumoral recurrence occurred and a new transurethral resection revealed sarcomatoid carcinoma with osseous elements. A radical cystoprostatectomy was then carried out.

ABSTRACT

CONTEXTO: A profilaxia antibiótica nas ressecções transuretrais da próstata é uma prática regular e freqüente na clínica urológica. No entanto, seu efeito profilático e bactericida protetor pode ser contestado se procedimentos assépticos são utilizados na realização da cirurgia, sobretudo em pacientes com urina estéril. No caso de infecção urinária, a identificação dos germes para escolha do antibiótico adequado pode ser necessária. OBJETIVO: Verificar a eficácia da antibioticoprofilaxia em pacientes com urina estéril submetidos a ressecção transuretral de próstata. TIPO DE ESTUDO: Prospectivo num centro de referência de tratamento urológico, aberto. LOCAL: Hospital de referência terciária. PARTICIPANTES: 124 pacientes. VARIÁVEIS ESTUDADAS: 124 pacientes consecutivos foram randomicamente divididos em dois grupos para receber ou não antibioticoterapia profilática na ressecção transuretral de próstata. Cultura do meato uretral, urina, líquido irrigante e anti-séptico, além dos fragmentos de próstata ressecados foram analisados quanto a sensibilidade a antibióticos, escolhidos a critério do cirurgião, e determinada a partir de antibiograma com as cepas bacterianas identificadas nos sítios mencionados. RESULTADOS: Não se encontrou diferença estatisticamente significante na evolução clínica de ambos os grupos. Aqueles que receberam antibioticoprofilaxia apresentaram menor freqüência de cultura urinária positiva do que aqueles que não receberam profilaxia. No entanto, na observação da evolução clínica de ambos os grupos, o uso de antibiótico não mostrou qualquer benefício no que concerne à ocorrência de febre, positividade das culturas obtidas dos fragmentos de próstata ressecados ou episódios de bacteremia. 68 casos (57,1%) apresentaram cultura positiva do tecido prostático. Entretanto, não houve correlação entre a bactéria identificada a partir do tecido prostático e de outros locais, tais como meato, urina, líquido irrigante ou anti-séptico utilizado. Somente em seis casos foi encontrada a mesma bactéria no tecido prostático e na urina pós-operatória. Apenas em 15 casos (25%) do grupo antibiótico observou-se a sensibilidade esperada da bactéria identificada ao antibiótico utilizado...

ABSTRACT

OBJETIVOS: Pacientes com carcinoma de células renais (CCR) quando diagnosticados precocemente têm maior possibilidade de cura com o tratamento cirúrgico. Este estudo tem como objetivo analisar as características anatomopatológicas dos espécimes cirúrgicos que justificam a diferença da história natural dos pacientes com CCR incidental e sintomático. MÉTODOS: Foram estudados retrospectivamente 115 pacientes submetidos a nefrectomia por CCR esporádico, divididos em Grupo 1: 59 pacientes assintomáticos com diagnóstico incidental e Grupo 2: 56 pacientes sintomáticos. A média de idade dos pacientes foi de 59 anos, com 86 homens e 29 mulheres. Cirurgia radical foi realizada em 96 pacientes e cirurgia conservadora em 19 casos. Foram analisadas as características anatomopatológicas, incluindo grau nuclear, estadio patológico, tamanho do tumor e presença de invasão microvascular intratumoral, sendo estes parâmetros comparados com a sobrevida dos pacientes. RESULTADOS: Ao compararmos os dois grupos, confirmou-se que os tumores incidentais têm menor grau nuclear (p=0,003), menor tamanho (p=0,001), menor incidência de invasão microvascular (p<0,001) e mais baixo estadio (p<0,001). A probabilidade de sobrevida do grupo incidental foi significativamente maior quando comparada ao grupo sintomático (p<0,001). CONCLUSAO: Os CCR descobertos incidentalmente têm características anatomopatológicas mais favoráveis e estes pacientes têm maiores chances de sobrevida livre de doença quando comparados com os CCR sintomáticos.

ABSTRACT

INTRODUCTION: Approximately 85 percent of patients who die from prostate cancer have bone metastases. Even though the radiological aspect of such metastases is osteoblastic, we currently know that these lesions are mixed, with coexisting blastic and lytic lesions, always beginning with bone lysis by osteoclast proliferation. Treatment options are palliative and have poor response, and when there is an improvement it is usually short-lived. This work intends to study the effect of clodronate in the treatment of skeletal complications of prostate cancer. MATERIALS AND METHODS: In an open prospective study 32 patients with hormone refractory prostate cancer with metastases to bones were assessed, in the period between November 2000 and September 2002. Mean age was 69 years (51 to 83 years). Patients were previously assessed by a pain scale and Karnofsky index. They underwent bone scintigraphy, X-ray, dosage of prostate specific antigen (PSA) and biochemical tests before and following treatment (administration of intravenous clodronate every 28 days). The Student's t-test was used for statistical analysis. RESULTS: Twenty-nine patients (90.6 percent) showed improvement after the first and the 2nd cycles, which persisted for at least 4 months. Average on the pain scale improved from 7.7 to 2.1 and Karnofsky index raised from 42 to 71. Radiological aspect of the metastases improved in 15 patients (46.8 percent) and side effects were low (only 2 patients - 6.2 percent). CONCLUSION: Bisphosphonate was effective in the treatment of skeletal complications of prostate cancer, presenting an objective response in 90.6 percent of treated patients, with a marked improvement in the pain scale, Karnofsky index and consequently in the quality of life of patients, and with low side effects.

ABSTRACT

OBJETIVOS: O comportamento do carcinoma de células renais estádio PT1 näo está completamente esclarecido. Nós estudamos a presença de fatores prognósticos e tamanho tumoral na recorrência e sobrevida do carcinoma de rim esporádico após tratamento cirúrgico. MÉTODOS: Foram revisados retrospectivamente 120 pacientes, 93 PT1, nove PT2, 11 PT3, sete PT4, seguidos após nefrectomia. Foram analisadas sobrevida e recorrência da doença dentro de três grupos de tumores: grupo 1: < 4cm, grupo 2: 4-7 cm e grupo 3: >7 cm e os fatores prognósticos preditivos avaliados foram grau nuclear, invasäo microvascular, presença de gânglios comprometidos e degeneraçäo sarcomatosa RESULTADOS: A freqüência de fatores prognósticos adversos aumenta à medida que aumenta o tamanho do tumor. No grupo 1 tivemos apenas quatro tumores de alto grau e somente um apresentou invasäo microvascular näo havendo gânglios comprometidos ou degeneraçäo sarcomatosa. No grupo 2 havia 16 tumores de alto grau, quatro sarcomatosos, dois com invasäo microvascular positiva e dois com gânglios positivos. No grupo 3, encontraram-se 18 tumores de alto grau, 15 com invasäo microvascular e sete com gânglios positivos e cinco sarcomatosos. Houve significância estatística na sobrevida câncer específica (p=0,002) e livre de doença (p=0,0002) entre os três grupos. CONCLUSÄO: A evoluçäo dos tumores PT1 é distinta para tumores menores de 4 cm e de 4-7 cm cabendo a subdivisäo destes dois grupos em T1a e T1b

ABSTRACT

Objetivo: Estudar a presença da invasäo vascular microscópica intratumoral e a evoluçäo dos pacientes submetidos à nefrectomia devido ao câncer renal. Material e métodos: De Janeiro/88 a Julho/99, 115 pacientes submeteram-se ao tratamento cirúrgico para o carcinoma de células renais. Um único patologista revisou todas as amostras anátomo-patológicas, procurando células neoplásicas na microcirculaçäo do tumor. Resultado: O tamanho do tumor variou de 0,5 a 19,5 cm (5,9 ñ 2,9). Três tumores mediam até 4 cm (7 por cento), 9 (21 por cento) entre 4,1 e 7 cm, 8 (42 por cento) entre 7,1 e 10 cm, e 6 (50 por cento) mediam mais do que 10 cm (p<0,001). Invasäo vascular microscópica foi observada em 23 por cento dos casos, sendo 7 por cento em tumores diagnosticados incidentalmente e 39 por cento em tumores sintomáticos (p<0,001). Até o final do estudo, houve 5 casos de progressäo da doença e 8 mortes, nos casos onde havia invasäo vascular microscópica. Na ausência da invasäo, apenas 1 progressäo e 2 mortes foram observadas. Conclusäo: Nesta série, a presença de invasäo vascular microscópica associou-se a um aumento importante da morbimortalidade. Essa descoberta representa um outro fator prognóstico das taxas de sobrevida dos pacientes com carcinoma de células renais.

ABSTRACT

CONTEXT: Renal cell carcinoma is the third most frequent genitourinary neoplasia, and there is currently an increase in the incidental diagnosis of tumors confined to the kidneys. OBJECTIVE: To study the survival of patients with incidental and symptomatic renal tumors who have undergone nephrectomy.DESIGN: Retrospective. SETTING: Hospital Sírio Libanês and Beneficência Portuguesa de São Paulo. PARTICIPANTS: 115 patients with diagnosis of renal cell carcinoma, operated on by the same group of surgeons and evaluated by a single pathologist. MAIN MEASUREMENTS: Sex, age and diagnosis method, analyzed in two groups, according to the tumor diagnosis: Group 1 with incidental diagnosis and Group 2 with symptomatic tumors. The anatomopathological characteristics and patient survival in both groups were evaluated. A statistical analysis was performed using the Student t, chi-squared, log rank and Kaplan-Meyer tests. RESULTS: Among the studied patients, 59(51 percent) had an incidental diagnosis, with 78 percent diagnosed by ultrasonography, 20 percent by computerized tomography scan and 2 percent during surgeries; 56 patients (49 percent) were symptomatic. Tumor locations were equally distributed between the two kidneys, and the surgery was conservative for 24 percent of the incidental and 9 percent of the symptomatic group. In the incidental group only one patient had tumor progression and there was no death, while in the symptomatic group there were 5 progressions and 10 deaths. The 5-year specific cancer-free survival was 100 percent in the incidental and 80 percent in the symptomatic group (p = 0.001) while the disease-free rate was 98 percent in the incidental and 62 percent in the symptomatic group (p < 0001). CONCLUSION: Incidental renal tumor diagnosis offers better prognosis, providing longer disease-free survival

ABSTRACT

CONTEXT: Multiple genetic and epigenetic factors have been implicated in the oncogenesis and progression of prostate cancer. The major difficulty is in that the clinical management stems from the reality that reliable and accurate prognostic biomarkers are not available and that effective treatment regimens forming hormone-resistant prostate cancers are yet to be developed. Among the most important regulators of apoptosis and programmed cell death is the bcl-2 gene and its related proteins. Elevated levels of bcl-2 protein may contribute to the progression of prostate cancers to a metastatic and hormone-insensitive state characterized by poor responses to chemotherapy. OBJECTIVE: To characterize the expression of bcl-2 proteins as a prognostic factor in humans. DESIGN: A retrospective approach. SETTING: Urology section, Federal University of Säo Paulo. DIAGNOSTIC TEST USED: Immunohistochemical analysis using bcl-2 protein antibody and normal staining by hematoxylin-eosin. MAIN MEASUREMENTS: Prognostic relations and protein expression were evaluated considering the total sample (28) divided into two groups, high (8 to 10) and low (2 to 4), separated according to the histological differentiation grade (Gleason score) with 10 and 18 samples, respectively. RESULTS: The differentiation of grade into two groups separated according to the Gleason score in low and high types presented different bcl-2 expression (P < 0.001). CONCLUSION: The higher frequency of bcl-2 immunostaining in tumor samples was observed in association with more advanced Gleason scores and suggests that an increase in the ratio of this anti-apoptotic protein often occurs during progression of prostate cancers

ABSTRACT

No momento do diagnóstico do câncer prostático, grande parte dos pacientes já tem doença disseminada. O tratamento com deprivaçäo androgênica é o mais indicado nesses casos, sendo a orquiectomia um método muito eficaz, que porém pode trazer consequências psicológicas. Alguns autores defendem a orquiectomia total (OT) com o argumento de que células de Leydig podem permanecer na albugínea quando a orquiectomia subcapsular (OS) é realizada, podendo comprometer a deprivaçäo hormonal. Com o objetivo de comparar a OT com a OS foi realizado um estudo com 58 pacientes com câncer de próstata estádio-D2, divididos em 2 grupos randomizados (grupo A: pacientes submetidos a OT e grupo B: 30 pacientes com OS). Dosou-se a testosterona total e o PSA imediatamente antes da cirurgia e 6 meses após. Utilizou-se o teste "t" de student para comparaçäo entre os grupos, näo sendo encontrada diferença entre eles. Conclui-se que as duas técnicas säo semelhantes sendo que a OS tem a vantagem de diminuir os traumas psicológicos e diminuir custos com a colocaçäo de próteses

ABSTRACT

Com o objetivo de avaliar o comportamento dos fios de sutura absorvíveis em contato com urina estéril, urina contaminada por Escherichia coli e por Proteus mirabilis, foram utilizadas 90 ratas Wistar, distribuídas em três grupos de 30 animais cada, e também três tipos de fios de sutura absorvíveis (poligliconato, categute cromado e poliglactina 910). A alta concentraçäo de amônia na urina infectada por Proteus mirabilis alterou a resistência tênsil dos fios absorvíveis sintéticos. Existiu também uma relaçäo direta entre a distribuiçäo dos fios de poliglactina 910 e a quantidade de amônia na urina

ABSTRACT

A litogenesia dos fios de sutura absorvíveis foi estudada em urina estéril e em urina contaminada por Escherichia coli e Proteus mirabilis, de ratos. Concluiu-se que o fio absorvível sintético monofilamentar poligliconato) foi o fio menos litogênico e que a presença de infecçäo aumenta a litogenesia do fio

ABSTRACT

Para estudar o efeito do pH e da urina infectada por E. coli e Proteus mirabilis sobre o categute cromado, o ácido poliglicólico (PGA) e a poliglactina 910 (P 910), dividimos o experimento em três partes. Na primeira, estudamos o comportamento dos fios imersos na urina estéril, infectada por E. coli e Proteus mirabilis, e no meio de cultura contaminado por Proteus mirabilis. Acompanhamos diariamente até o 6§ dia o aspecto físico. Na segunda parte, estudamos isoladamente cada elemento da reaçäo de desdobramento de uréia, sem a presença de bactérias, e na tercera parte mimetizamos essa reaçäo em meio estéril e com pH ácido e alcalino. Enquanto o categute cromado se manteve íntegro em todos os meios, o PGA e o P.910 dissolveram-se na urina infectada por Proteus devido à amônia resultante do desdobramento da uréia. Essa dissoluçäo também foi constatada em meio estéril (mimetizaçäo da reaçäo de desdobramento da uréia pela urease sem o Proteus). A variaçäo do pH näo influenciou a destruiçäo dos fios

ABSTRACT

Esse trabalho tem como objetivo estudar a concentraçäo mínima de amônia necessária para dissolver os fios de sutura absorvíveis sinéticos, e a relaçäo entre essa concentraçäo e o tempo de dissoluçäo do fio. Foram utilizados diferentes concentraçöes de hidróxido de amônio (NH4), variando de 1 até 0,01 mol/1. Constatamos que existe uma relaçäo direta entre a concentraçäo de amônia, o tempo de contato e a dissoluçäo do fio. A concentraçäo mínima de amônia necessária para dissolver os fios é muito próxima da concentraçäo normal de amônia na urina
