Analysis of Correlation and Agreement between the Uroflowmetry and the International Prostate Symptom Score in Patients after retropubic Radical Prostatectomy: A Multicenter Prospective Study[*] / Análisis de correlación y concordancia entre la uroflujometría y la escala internacional de síntomas prostáticos posterior a prostatectomía radical retropúbica: estudio multicéntrico prospectivo

Objectives Patients undergoing retropubic radical prostatectomy (RRP) may suffer from lower urinary tract symptoms (LUTS). We aim to characterize LUTS and to evaluate the correlation and agreement between uroflowmetry and the International Prostate Symptom Score (IPSS) in patients after RRP in two reference centers. Methods An observational multicenter prospective study was conducted between December 2015 and September 2016. Patients with at least 12-months of follow-up after RRP were included; these were evaluated with uroflowmetry and the IPSS. Results A total of 90 patients were included. The mean follow-up was of 54.6 months (standard deviation [SD] = 27.52), and the mean age was 65 (SD = 6.85) years old. The mean IPSS was 7.41 (SD = 6.29), with 33.3% (n = 54) of the patients with moderate symptoms and 6.7% (n = 6) with severe symptoms. A total of 50% (n = 45) of the patients had normal uroflowmetry. Patients with an abnormal/equivocal result in the uroflowmetry had a mean of 9.31 (SD = 7.03) points in the IPSS versus 5.51 (SD = 4.82) in patients with a normal uroflowmetry result (p < 0.01). The level of agreement between mild versus moderate-to-severe LUTS and normal uroflowmetry versus abnormal/equivocal was 61.1% (k = 0.22, p = 0.04). We found that a score ≥ 10 in the IPSS had a level of agreement of 65.6% (k = 0.31, p = 0.0004). Conclusions We consider that although the IPSS cannot replace uroflowmetry and vice versa, these tests are complementary and may be useful tools in the evaluation of patients with LUTS after RRP.

Objetivos Los pacientes en quienes se realiza prostatectomía radical retropúbica (PRR) pueden sufrir de síntomas del tracto urinario inferior (STUIs). El propósito es poder caracterizar STUI y correlacionarlos con la uroflujometría y la Escala Internacional de Síntomas Prostáticos (IPSS por sus siglas en inglés). Métodos Se realizó un estudio multicéntrico prospectivo entre Diciembre de 2015 y Septiembre de 2016. Se incluyeron todos los pacientes con un seguimiento mínimo de 12 meses después de la PRR. Estos fueron evaluados con uroflujometría e IPSS. Resultados Se incluyeron un total de 90 pacientes. El seguimiento promedio fue de 54,6 meses (desviación estándar [DE] = 27,52), la edad promedio fue de 65 años (DE 6,85). El promedio de la puntuación en la IPSS fue de 7,41 (DE = 6,29) con 33,3% de los pacientes con síntomas moderados y 6,7% con síntomas severos. El 50% de los pacientes tuvieron una uroflujometría normal. Los pacientes con resultado anormal o equívoco en la uroflujometría presentaron un promedio de 9,31 (DE = 7,03) en la puntuación de la IPSS, versus 5,51 (DE = 4,82) en pacientes con una uroflujometría normal (p < 0,01). El nivel de concordancia entre los STUIs leves y moderados/severos y uroflujometría normal versus anormal/equívoca fue de 61,1% (k = 0,22, p = 0,04). Se encontró que un puntaje ≥ 10 en la IPSS tiene un nivel de concordancia del 65,6% (k = 0.31, p = 0.0004). Conclusiones Se considera que aunque la IPSS no puede reemplazar la uroflujometría y viceversam, estas pruebas son complementarias, y son herramientas útiles en la evaluación de pacientes con STUIs después de la PRR.

Experiências sexuais após prostatectomia radical não poupadora de nervos / Experiencias sexuales después de prostatectomía radical sin conservación de bandeletas neurovasculares / Sexual experiences after non-nerve sparing radical prostatectomy

Resumo Objetivo O objetivo deste estudo foi explorar as experiências e expectativas de pacientes submetidos a prostatectomia radical não poupadora de nervos. Métodos Estudo qualitativo, descritivo-exploratório, baseado na fenomenologia hermenêutica. Foram realizadas dezesseis entrevistas em profundidade entre fevereiro e dezembro de 2017 e análise indutiva dos dados. Resultados Dois temas que refletem as experiências dos pacientes emergiram da análise: (1) As mudanças sexuais como fator-chave da resposta adaptativa, com os subtemas "Dificuldades sexuais após a cirurgia" e "Questões com relacionamentos íntimos e bem-estar psicossocial"; (2) Prostatectomia: a necessidade de adaptação a uma sexualidade holística, com os subtemas "Questionamento das experiências a partir do comportamento sexual atual" e "Adaptação da sexualidade e a intimidade após a cirurgia". Conclusão Pacientes submetidos à prostatectomia enfrentam dificuldades sexuais como disfunção erétil. Essas mudanças causam problemas nos relacionamentos sexuais e íntimos que afetam seu bem-estar. Diante dessa situação, alguns participantes questionam suas práticas sexuais habituais e tentam se adaptar a uma sexualidade holística não centrada no coito, incorporando formas inovadoras de sexualidade. Conhecer as experiências de homens submetidos a prostatectomia radical pode ajudar os profissionais de saúde a oferecer novas estratégias para lidar com as mudanças ambientais envolvidas na cirurgia da próstata.

Métodos Estudio cualitativo, descriptivo-exploratorio, basado en la fenomenología hermenéutica. Se realizaron 16 entrevistas en profundidad entre febrero y diciembre de 2017 y un análisis inductivo de los datos. Resultados A partir del análisis, surgieron dos temas que reflejan las experiencias de los pacientes: (1) Los cambios sexuales como factor clave de la respuesta adaptativa, con dos subtemas "Dificultades sexuales después de la cirugía" y "Cuestiones sobre relaciones íntimas y bienestar psicosocial" y (2) Prostatectomía: necesidad de adaptación a una sexualidad holística, con los subtemas "Cuestionamiento de las experiencias a partir del comportamiento sexual actual" y "Adaptación de la sexualidad e intimidad después de la cirugía". Conclusión Los pacientes sometidos a prostatectomía enfrentan dificultades sexuales como disfunción eréctil. Estos cambios causan problemas en las relaciones sexuales e íntimas que afectan su bienestar. Ante esta situación, algunos participantes cuestionan sus prácticas sexuales habituales e intentan adaptarse a una sexualidad holística no centrada en el coito, incorporando formas innovadoras de sexualidad. Conocer las experiencias de hombres sometidos a prostatectomía radical puede ayudar a los profesionales de la salud a ofrecer nuevas estrategias para lidiar con los cambios ambientales relacionados con la cirugía de próstata.

Abstract Objective The aim of this study was to explore the experiences and expectations of patients who underwent non-nerve sparing radical prostatectomy. Methods A qualitative descriptive, exploratory, study, based on hermeneutic phenomenology. Sixteen in-depth interviews were carried out between February and December 2017. An inductive analysis of data was performed. Results Two themes reflecting the patients' experiences emerged from the analysis: (1) Sexual changes as a key factor of the adaptive response, with the subthemes "Sexual difficulties after surgery" and "Issues with intimate relationships and psychosocial wellbeing". (2) Prostatectomy: the need of adaptation to a holistic sexuality, with the subthemes "Questioning the experiences from the current sexual behavior" and "Adapting sexuality and intimacy after surgery". Conclusion Patients undergoing prostatectomy face sexual difficulties such as erectile dysfunction. These changes cause problems in sexual and intimate relationships that affect their wellbeing. Given this situation, some participants question their usual sexual practices and try to adapt to a holistic sexuality not centered on coitus by incorporating innovative forms of sexuality. Knowing the experiences of men who underwent radical prostatectomy might help healthcare workers to provide new strategies for coping with the environmental changes involved in prostate surgery.

Assessment of the lower urinary tract symptoms after robotic-assisted radical prostatectomy: the behavior of voiding, storage and post micturition symptoms / Avaliação dos sintomas do trato urinário inferior após prostatectomia radical robótica-assistida: o comportamento dos sintomas de esvaziamento, armazenamento e pós-miccionais

ABSTRACT Introduction: despite being infrequent, urinary incontinence has a huge impact on the quality of life of patients undergoing radical prostatectomy, even with the robotic-assisted technique. Objective: to assess the evolution of urinary symptoms from preoperative to 12 months after robotic-assisted radical prostatectomy. Methods: data was collected from 998 patients who underwent robotic-assisted radical prostatectomy. Demographic data, preoperative and postoperative information on patients were documented. The ICIQ and IPSS questionnaires were also applied preoperatively and after 1, 3, 6 and 12 months after the operation. Results: Out of 998 patients, 257 correctly completed all questionnaires. The mean age of the patients was 60 ± 0.74 years. We found that the total IPSS increased initially and at 6 months after the operation, it was already lower than the initial preoperative value (7.76 at 6 months vs. 9.90 preoperative, p <0.001), being that questions regarding voiding symptoms were the first to improve followed by the questions regarding post micturition and storage symptoms. As for the ICIQ variables, there was an increase with radical prostatectomy and none of them returned to the preoperative level (p<0.001). Conclusions: robotic assisted radical prostatectomy causes, at first, a worsening of urinary symptoms in the lower tract with subsequent recovery. Recovery begins with voiding symptoms, followed by post micturition and storage symptoms. The symptoms assessed by the IPSS evolve to better parameters even than those of the preoperative period, while the symptoms of incontinence assessed by the ICIQ do not reach the preoperative levels in the studied interval.

RESUMO Introdução: apesar de infrequente, a incontinência urinária gera imenso impacto na qualidade de vida dos pacientes submetidos a prostatectomia radical, mesmo com a técnica robótica-assistida. Objetivo: avaliar a evolução dos sintomas urinários desde o pré-operatório até 12 meses após a prostatectomia radical robótica-assistida. Métodos: foram coletados os dados de 998 pacientes submetidos à prostatectomia radical robótica-assistida. Foram documentados dados demográficos, informações pré-operatórias e pós-operatórias dos pacientes. Também foram aplicados os questionários ICIQ e IPSS no pré-operatório e após 1, 3, 6 e 12 meses de pós-operatório. Resultados: de 998 pacientes, 257 preencheram corretamente todos os questionários. A idade média dos pacientes foi de 60±0,74 anos. Verificou-se que o IPSS total subia inicialmente e aos 6 meses após a operação, este já se tornava inferior ao valor inicial pré-operatório (7,76 aos 6 meses vs. 9,90 pré-operatório, p<0.001), sendo que as questões referentes a sintomas de esvaziamento foram as primeiras a melhorar e posteriormente as questões referentes a sintomas pós-miccionais e de armazenamento. Quanto às variáveis do ICIQ, houve elevação com a prostatectomia radical e nenhuma delas retornou ao patamar pré-operatório (p<0,001). Conclusões: a prostatectomia radical robótica assistida causa num primeiro momento uma piora nos sintomas urinários do trato inferior com uma recuperação subsequente. A recuperação se inicia pelos sintomas de esvaziamento, seguido dos sintomas pós-miccionais e de armazenamento. Os sintomas avaliados pelo IPSS acabam evoluindo a parâmetros melhores inclusive que os do pré-operatório, enquanto os sintomas de perda urinária avaliados pelo ICIQ não atingem os níveis pré-operatórios no intervalo estudado.

Nursing diagnoses and NIC interventions in adult males undergoing radical prostatectomy / Diagnósticos de Enfermagem e intervenções NIC em adultos do sexo masculino que passaram por prostatectomia radical / Diagnósticos de Enfermería e intervenciones NIC en adultos del sexo masculino que pasaron por prostatectomía radical

ABSTRACT Objective: To determine NANDA-I nursing diagnoses and NIC nursing interventions in patients who underwent radical prostatectomy. Method: A cross-sectional and descriptive study was conducted in a research and teaching hospital in western Turkey between June 2016 and June 2017. The sample included adult patients diagnosed with prostate cancer in the immediate postoperative period of radical prostatectomy. Data collection was performed using Gordon's Functional Health Patterns, NANDA-International and Nursing Interventions Classification Taxonomy Systems. Results: Participants were 54 adult patients. The main nursing diagnoses were in the classes of "physical injury", "self-care", "hydration" and "physical comfort". Some nursing diagnoses were identified in all patients, namely: "risk for deficient fluid volume", "risk for imbalanced fluid volume", "impaired urinary elimination". The most selected NIC interventions were in the classes of "risk management", "elimination management", "coping assistance", "tissue perfusion management" and "self-care facilitation". Conclusion: future studies with larger populations are needed to explore the nursing diagnoses and effects of nursing interventions on patients who underwent radical prostatectomy.

Resumo Objetivo: Determinar os diagnósticos de enfermagem da NANDA-I e as intervenções de enfermagem (NIC) em pacientes que passaram por prostatectomia radical. Método: um estudo transversal e descritivo foi realizado em um hospital universitário e de pesquisa na Turquia ocidental entre junho de 2016 e junho de 2017. A amostra incluiu pacientes adultos diagnosticados com câncer de próstata no período pós-operatório imediato da prostatectomia radical. A coleta de dados foi realizada usando os padrões funcionais de saúde de Marjory Gordon, NANDA-Internacional e os sistemas de taxonomia para a classificação das intervenções de enfermagem. Resultados: Participaram 54 pacientes adultos. Os principais diagnósticos de enfermagem foram nas classes de "lesão física", "autocuidado", "hidratação" e "conforto físico". Alguns diagnósticos de enfermagem foram identificados em todos os pacientes, especificamente: "risco para volume de líquidos deficiente", "risco para volume de líquidos desequilibrado", "eliminação urinária prejudicada". As intervenções (NIC) mais selecionadas foram nas classes de "manejo de riscos", "manejo da eliminação", "assistência de cobertura", "manejo da perfusão tecidual" e "facilitação do autocuidado". Conclusão: Estudos futuros com populações maiores são necessários para explorar os diagnósticos de enfermagem e os efeitos das intervenções de enfermagem em pacientes que passaram por prostatectomia radical.

Resumen Objetivo: Determinar los diagnósticos de enfermería de la NANDA-I y las intervenciones de enfermería (NIC) en pacientes que pasaron por prostatectomía radical. Método: Un estudio transversal y descriptivo fue realizado en un hospital universitario y de investigación en Turquía occidental entre junio de 2016 y junio de 2017. La muestra incluyó a pacientes adultos diagnosticados con cáncer de próstata en el período posoperatorio inmediato de la prostatectomía radical. La recolección de los datos se llevó a cabo utilizándose los patrones funcionales del paciente de Marjory Gordon, NANDA Internacional y los sistemas de taxonomía para la clasificación de las intervenciones enfermeras. Resultados: Participaron 54 pacientes adultos. Los principales diagnósticos de enfermería fueron en las clases de "daño físico", "autocuidado", "hidratación" y "comodidad física". Algunos diagnósticos enfermeros fueron identificados en todos los pacientes, específicamente: "riesgo para volumen de líquidos deficiente", "riesgo para volumen de líquidos desequilibrado", "eliminación urinaria perjudicada". Las intervenciones (NIC) más seleccionados fueron en las clases de "manejo de riesgos", "manejo de la eliminación", "asistencia de cobertura", "manejo de la perfusión tisular" y "facilitación del autocuidado". Conclusión: Estudios futuros con poblaciones más grandes son necesarios para explorar los diagnósticos de enfermería y los efectos de las intervenciones enfermeras en pacientes que pasaron por prostatectomía radical.

Serving as a bedside surgeon before performing robotic radical prostatectomy improves surgical outcomes

ABSTRACT Introduction: To evaluate the influence of previous experience as bedside assistants on patient selection, perioperative and pathological results in robot assisted laparoscopic radical prostatectomy. Materials and Methods: The first 50 cases of two robotic surgeons were reviewed retrospectively. Group 1 consisted of the first 50 cases of the surgeon with previous experience as a robotic bedside assistant between September 2016-July 2018, while Group 2 included the first 50 cases of the surgeon with no bedside assistant experience between February 2009-December 2009. Groups were examined in terms of demographics, prostate volume, presence of median lobe, prostate specific antigen (PSA), preoperative Gleason score, positive core number, clinical stage, console surgery time, estimated blood loss, postoperative Gleason score, pathological stage, positive surgical margin rate, postoperative complications, length of hospital stay and biochemical recurrence rate. Results: Previous abdominal surgery and the presence of median lobe hypertrophy rates were higher in Group 1 than in Group 2 (20% vs. 4%, p=0.014; 24% vs. 6%, p=0.012; respectively). In addition, patients in Group 1 were in a higher clinical stage than those in Group 2 (cT2: 70% vs. 28%, p=0.001). Median console surgery time and median length of hospital stay was significantly shorter in Group 1 than in Group 2 (170 min vs. 240 min, p=0.001; 3 vs. 4, p=0.022; respectively). Clavien grade 3 complication rate was higher in Group 2 but was statistically insignificant. Conclusion: Our findings might reflect that previous bedside assistant experience led to an increase in self-confidence and the ability to manage troubleshooting and made it more likely for surgeons to start with more difficult cases with more challenging patients. It is recommended that novice surgeons serve as bedside assistants before moving on to consoles.

Impact of time from biopsy to surgery on complications, functional and oncologic outcomes following radical prostatectomy

ABSTRACT Introduction: To determine the impact of time from biopsy to surgery on outcomes following radical prostatectomy (RP) as the optimal interval between prostate biopsy and RP is unknown. Material and methods: We identified 7, 350 men who underwent RP at our institution between 1994 and 2012 and had a prostate biopsy within one year of surgery. Patients were grouped into five time intervals for analysis: ≤ 3 weeks, 4-6 weeks, 7-12 weeks, 12-26 weeks, and > 26 weeks. Oncologic outcomes were stratified by NCCN disease risk for comparison. The associations of time interval with clinicopathologic features and survival were evaluated using multivariate logistic and Cox regression analyses. Results: Median time from biopsy to surgery was 61 days (IQR 37, 84). Median follow-up after RP was 7.1 years (IQR 4.2, 11.7) while the overall perioperative complication rate was 19.7% (1,448/7,350). Adjusting for pre-operative variables, men waiting 12-26 weeks until RP had the highest likelihood of nerve sparing (OR: 1.45, p = 0.02) while those in the 4-6 week group had higher overall complications (OR: 1.33, p = 0.01). High risk men waiting more than 6 months had higher rates of biochemical recurrence (HR: 3.38, p = 0.05). Limitations include the retrospective design. Conclusions: Surgery in the 4-6 week time period after biopsy is associated with higher complications. There appears to be increased biochemical recurrence rates in delaying RP after biopsy, for men with both low and high risk disease.

Hubo correlación entre los aspectos psicosociales y algunas escalas de evaluación de calidad de vida, principalmente las escalas funcionales y de síntomas. Conclusión: Quedó en evidencia que la prostatectomía radical perjudica la calidad de vida de los hombres y demanda asistencia de los profesionales de la salud para minimizar los efectos de las complicaciones más comunes. Se recomienda la implementación de intervenciones educativas y de apoyo multiprofesional para una mejor comprensión de las consecuencias físicas y psicosociales para ayudar a mejorar la calidad de vida de los hombres después de la prostatectomía radical.

Abstract Objective: To investigate quality of life and its correlations with psychosocial factors (anxiety, depression and low self-esteem) in men who underwent prostatectomy. Methods: A descriptive, correlational study with 85 men who underwent radical prostatectomy at least three months and at most five years prior to the survey. The instruments used were the European Organization for Research and Treatment of Cancer- QLQ C30, the European Organization for Research and Treatment of Cancer "Prostate Cancer" 25 items - EORTC QLQ-PR25; the Rosenberg Self-Esteem Scale and the Hospital Anxiety and Depression Scale. Results: Participants showed impairment of quality of life associated with impairment of sexual function and presence of urinary symptoms. There was a correlation between the psychosocial aspects and some quality of life assessment scales, mainly the functional and symptom scales. Conclusion: It was shown that radical prostatectomy causes impairment in the quality of life of men, requiring care from health professionals to minimize the effects of the most common complications. Educational interventions and multi-professional support based on a better understanding of the physical and psychosocial implications are recommended to help improve the quality of life of men after radical prostatectomy.

Salvage radiotherapy for biochemical recurrence after radical prostatectomy: does the outcome depend on the prostate cancer characteristics?

ABSTRACT Objective: To build a model to evaluate the impact of salvage radiotherapy (SRT) in men with PSA rise or persistent PSA after undergoing radical prostatectomy (RP). Materials and Methods: The study included 107 node-negative patients treated with SRT after RP at a single institution. Patients received SRT for either prostate-specific antigen (PSA) rising, or PSA persistence after RP. All patients received local radiation to the prostate / seminal vesicle bed. The primary measured outcome was the biochemical recurrence (BCR) free survival. Multivariable Cox regression analysis was used to develop a risk-stratification group to identify predictive factors associated with the probability of BCR at 5yr. Results: At a median follow-up of 52 months, the BCR free survival rate and overall survival in 5 years was 73% and 94%, respectively. At multivariable analysis, pre-SRT PSA level > 0.35ng / mL (p = 0.023), negative margins (p = 0.038), and seminal vesicles invasion (p = 0.001) were significantly associated with BCR free survival. Three risk groups using regression analysis for SRT administration was built. Low-, intermediate- and the high-risk groups had a BCR free survival in 5-years of 96%, 84%, and 44% (p = 0.0001), respectively. Conclusions: We developed a risk group stratification to show the impact of SRT based on prostate cancer characteristics. SRT showed to be extremely beneficial for patients with low- and intermediate-risk tumors. Moreover, the risk-group built could identify patients classified as high-risk who might benefit from more aggressive treatment for SRT.

Effectiveness of a home care teaching program for prostatectomized patients: a randomized controlled clinical trial / Efectividad de un programa de enseñanza para cuidado domiciliario de pacientes prostatectomizados: ensayo clínico controlado randomizado / Efetividade de um programa de ensino para cuidado domiciliar de pacientes prostatectomizados: ensaio clínico controlado randomizado

ABSTRACT Objective: To evaluate the effectiveness of a teaching program for hospital discharge of patients submitted to radical prostatectomy based on the self-efficacy construct of the Cognitive Social Theory. Method: A controlled clinical trial carried out on a 2-month follow-up of 68 prostatectomized men randomized into intervention group (n = 34) and control (n = 34). The intervention group received routine guidance from the service plus the teaching program. The control group only received routine guidance from the service. The data collection instruments were: sociodemographic and clinical questionnaire, self-efficacy scale, hospital depression and anxiety scale, household care knowledge questionnaire, and an item on satisfaction with a score of 1 to 5. Results: There was a significant difference between the intragroups for satisfaction (p<0.001) and knowledge (p<0.001) of the pre-test to the post-test. In the intervention group, there were significant changes between the times for anxiety (p=0.011) and knowledge (p<0.001). Conclusion: The teaching program with a combination of oral guidance, written instruction and telephone follow-up was effective in improving knowledge about home care and personal satisfaction.

Impact of urinary incontinence on the quality of life of individuals undergoing radical prostatectomy / Impacto da incontinência urinária na qualidade de vida de indivíduos submetidos à prostatectomia radical / Impacto de la incontinencia urinaria en la calidad de vida de individuos sometidos a la prostatectomia radical

ABSTRACT Objective: to assess the level of urinary incontinence and its impact on the quality of life of patients undergoing radical prostatectomy. Method: cross-sectional study carried out with prostatectomized patients. The data were collected from the following instruments: sociodemographic questionnaire, Pad Test, International Consultation on Incontinence Questionnaire - Short Form and King Health Questionnaire. Data were submitted to descriptive and bivariate statistical analysis. The level of significance was set at 0.05. Results: a total of 152 patients participated, with a mean age of 67 years. Among incontinent patients, there was a predominance of mild urinary incontinence. Urinary incontinence had a very severe impact on the general assessment of quality of life in the first months and severe impact after six months of surgery. The greater the urinary loss, the greater the impact on the quality of life domains Physical Limitations, Social Limitations, Impact of Urinary Incontinence and Severity Measures. Most participants reported no erection after surgery and therefore did not respond to the question of the presence of urinary incontinence during sexual intercourse. Conclusion: the present study evidenced the occurrence of urinary incontinence after radical prostatectomy at different levels and its significant impact on the quality of life of men, which reveals the need of interventions for controlling it.

RESUMO Objetivo: avaliar o nível de incontinência urinária e o seu impacto na qualidade de vida de pacientes submetidos à prostatectomia radical. Método: estudo transversal, realizado com pacientes prostatectomizados. Os dados foram coletados a partir dos seguintes instrumentos: questionário sociodemográfico, Pad Test, International Consultation on Incontinence Questionnaire - Short Form e King Health Questionnaire. Os dados foram submetidos à análise estatística descritiva e bivariada. O nível de significância adotado foi de 0,05. Resultados: participaram 152 pacientes, com idade média de 67 anos. Entre os pacientes incontinentes, houve predomínio da incontinência urinária leve. A incontinência urinária causou impacto muito grave na avaliação geral da qualidade de vida nos primeiros meses e grave após seis meses de cirurgia. Quanto maior a perda urinária, maior impacto nos domínios da qualidade de vida Limitações Físicas, Limitações Sociais, Impacto da Incontinência Urinária e Medidas de Gravidade. A maioria dos participantes relatou ausência de ereção após a cirurgia e por isso não respondeu à questão referente à presença de incontinência urinária durante a relação sexual. Conclusão: o estudo evidenciou a ocorrência da incontinência urinária após prostatectomia radical em diferentes níveis e o seu impacto significativo na qualidade de vida dos homens merecendo intervenções para o seu controle.

Predictive factors for prolonged hospital stay after retropubic radical prostatectomy in a high-volume teaching center

ABSTRACT Objective: To evaluate the length hospital stay and predictors of prolonged hospitalization after RRP performed in a high-surgical volume teaching institution, and analyze the rate of unplanned visits to the office, emergency care, hospital readmissions and perioperative complications rates. Materials and Methods: Retrospective analysis of prospectively collected data in a standardized database for patients with localized prostate cancer undergoing RRP in our institution between January/2010 - January/2012. A logistic regression model including preoperative variables was initially built in order to determine the factors that predict prolonged hospital stay before the surgical procedure; subsequently, a second model including both pre and intraoperative variables was analyzed. Results: 1011 patients underwent RRP at our institution were evaluated. The median hospital stay was 2 days, and 217 (21.5%) patients had prolonged hospitalization. Predictors of prolonged hospital stay among the preoperative variables were ICC (OR. 1.40 p=0.003), age (OR 1.050 p<0.001), ASA score of 3 (OR. 3.260 p<0.001), prostate volume on USG-TR (OR, 1.005 p=0.038) and African-American race (OR 2.235 p=0.004); among intra and postoperative factors, operative time (OR 1.007 p=0.022) and the presence of any complications (OR 2.013 p=0.009) or major complications (OR 2.357 p=0.01) were also correlated independently with prolonged hospital stay. The complication rate was 14.5%. Conclusions: The independent predictors of prolonged hospitalization among preoperative variables were CCI, age, ASA score of 3, prostate volume on USG-TR and African-American race; amongst intra and postoperative factors, operative time, presence of any complications and major complications were correlated independently with prolonged hospital stay.

Diagnostic accuracy of multiparametric magnetic resonance imaging in detecting extracapsular extension in intermediate and high - risk prostate cancer

ABSTRACT Objectives: To evaluate the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) as a predictor of extracapsular extension (ECE) and unfavorable Gleason score (GS) in patients with intermediate and high-risk prostate cancer (PCa). Materials and Methods: Patients with clinically localized PCa who underwent radical prostatectomy (RP) and had preoperative mp-MRI between May-2011 and December-2013. Mp-MRI was evaluated according to the European Society of Urogenital Radiology MRI prostate guidelines by two different readers. Histopathological RP results were the standard reference. Results: 79 patients were included; mean age was 61 and median preoperative prostate-specific antigen (PSA) 7.0. On MRI, 28% patients had ECE evidenced in the mp-MRI, 5% seminal vesicle invasion (SVI) and 4% lymph node involvement (LNI). At RP, 39.2% had ECE, 26.6% SVI and 12.8% LNI. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of mp-MRI for ECE were 54.9%, 90.9%, 76%, 81% and 74.1% respectively; for SVI values were 19.1%, 100%, 77.3%, 100% and 76.1% respectively and for LNI 20%, 98.4%, 86.7%, 66.7% and 88.7%. Conclusions: Major surgical decisions are made with digital rectal exam (DRE) and ultrasound studies before the use of Mp-MRI. This imaging study contributes to rule out gross extraprostatic extension (ECE, SVI, LNI) without competing with pathological studies. The specificity and NPV are reasonable to decide surgical approach. A highly experienced radiology team is needed to provide accurate estimations of tumor extension and aggressiveness.

Comparing the short - term outcomes and complications of monopolar and bipolar transurethral resection of bladder tumors in patients with coronary artery disese: a prospective, randomized, controlled study

ABSTRACT Introduction: To compare the perioperative outcomes and complications of monopolar and bipolar transurethral resection of bladder tumors (TURBT) in patients with coronary artery disease (CAD). Materials and Methods: A total of 90 CAD patients with newly diagnosed bladder cancer who underwent TURBT were randomized into monopolar TURBT (M-TURBT) and bipolar TURBT (B-TURBT) groups. Primary outcome was safety of the procedures including obturator jerk, bladder perforation, clot retention, febrile urinary tract infection and TUR syndrome. The secondary outcome was the efficacy of TURBT procedures, including complete tumor resection, sampling of the deep muscle tissue and sampling of the qualified tissues without any thermal damage. Results: Mean ages of the patients in M-TURBT and B-TURBT groups were 71.36±7.49 and 73.71±8.15 years, respectively (p=0.157). No significant differences were found between M-TURBT and B-TURBT groups regarding complete tumor resection (76.2% vs. 87.5%, p=0.162) and muscle tissue sampling rates (71.4% vs. 64.6%,p=0.252). Obturator jerk was detected in 16.7% of the patients in M-TURBT group and 2.1% in B-TURBT group (p=0.007). No statistically significant differences were found between the groups regarding intraoperative and postoperative complications. Conclusions: Both monopolar and bipolar systems can be used safely and effectively during TURBT procedure in CAD patients. Due to the more frequently seen obturator jerk in M-TURBT than B-TURBT, careful surgical approach is needed during M-TURBT.

The association between the outcomes of extraperitoneal laparoscopic radical prostatectomy and the anthropometric measurements of the prostate by magnetic resonance imaging

ABSTRACT Introduction and objective To determine the association between the anthropometric measurements by magnetic resonance imaging (MRI) and perioperative outcomes of extraperitoneal laparoscopic radical prostatectomy (ELRP). Materials and Methods From 2008 to June 2016, 86 patients underwent preoperative MRI prior to undergoing ELRP for localized prostate cancer. We analyzed the associations between anthropometric measurements of MRI and the perioperative outcomes of patients who underwent ELRP. Results The mean patient age was 69.61±8.30 years. The medians of operating time and blood loss were 2.30 hours and 725.30ml, respectively. The total post-surgical complication rate was 1.16%. The median hospital stay was 6.50 days. The pathological stages for T2 and T3 were 45.74% and 34.04%, respectively. The rate as positive surgical margins (PSMs) was 18.09% (pT2 and pT3; 6.38% and 9.57%). The angles between pubic bone and prostate gland (angle 1&2), were significantly associated with operative time and hospital stay, respectively (p<0.05). There was no correlation between the pelvimetry and positive surgical margin. Conclusions The findings of the present study suggest that anthropometric measurements of the MRI are related to operative difficulties in ELRP. This study confirmed that MRI planning is the key to preventing complications in ELRP.

Prospective evaluation of vesicourethral anastomosis outcomes in robotic radical prostatectomy during early experience in a university hospital

ABSTRACT Purpose: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. Materials and Methods: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. Results: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. Conclusion: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.

Open radical prostatectomy reproducing robot-assisted radical prostatectomy: Involving antegrade nerve sparing and continuous anastomosis

ABSTRACT Purpose: To present modified RRP using the same method as RALP and compare its surgical outcomes with RALP. Materials and Methods: Demographics, perioperative and functional outcomes of the 322 patients that underwent RRP (N=99) or RALP (N=223) at our institution from January 2011 through June 2013 were evaluated retrospectively. Postoperative incontinence and erectile dysfunction are involved functional outcomes. During the modified procedure, the bladder neck was dissected first as for RALP. After dissection of vas deference and seminal vesicle, the prostate was dissected in an antegrade fashion with bilateral nerve saving. Finally, the urethra was cut at the prostate apex. After a Rocco suture was applied, and then urethrovesical anastomosis was performed with continuous suture as for RALP. Results: Perioperative characteristics and complication rates were similar in the RRP and RALP groups except for mean estimated blood loss (p<0.001) and operative time (p<0.001). Incontinence rates at 3 and 12 months after RRP decreased from 67.6% to 10.1 and after RALP decreased from 53.4% to 5.4%. Positive surgical margin rates were non-significantly different in the RRP and RALP groups (30.3% and 37.2%, respectively). Overall postoperative potency rate at 12 months was not significant different in RRP and RALP groups (34.3% and 43.0%). Conclusions: RRP reproducing RALP was found to have surgical outcomes comparable to RALP. This technique might be adopted by experienced urologic surgeons as a standard procedure.

Artificial urinary sphincter for urinary incontinence after radical prostatectomy: a historical cohort from 2004 to 2015

ABSTRACT This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS implant, provided by a private nonprofit HMO operating in Belo Horizonte, Brazil. On total, there were 91 AUS implants, with a median interval between radical prostatectomy and AUS implant of 3.6 years (IQR 1.9 to 5.5). The rate of AUS cumulative survival, after a median follow-up of 4.1 years (IQR 1.7-7.2 years), was 44% (n=40). The median survival of AUS implants was 2.9 years (IQR 0.5-7.9 years). Thirty-seven AUS implants (40.7%) resulted in grade III surgical complications. There were 5 deaths at 2.1, 4.7, 5.7, 5.7 and 6.5 years of follow-up, but none due to causes directly associated to the AUS implant. Persistent severe incontinence was documented in 14 (15.3%) additional patients. From the 51 AUS implants which resulted in grade III surgical complications or persistent severe incontinence, 24 (47.1%) underwent surgical revisions. Explantation of the sphincter or its components was observed in 6 cases (25.0%). Mechanical failure, described as fluid loss and/or inability to recycle the AUS device, was observed in 4 devices (16.7%). In conclusion, although AUS implants are recommended as the gold-standard treatment of severe urinary incontinence after prostatectomy, the observed high rates of malfunction and grade III adverse events are a matter of concern warranting further assessment on the safety and efficacy of these devices.

4-Ports endoscopic extraperitoneal radical prostatectomy: preliminary and learning curve results

ABSTRACT Introduction There is a lack of studies in our national scenario regarding the results obtained by laparoscopic radical prostatectomy technique (LRP). Except for a few series, there are no consistent data on oncological, functional, and perioperative results on LRP held in Brazil. As for the LRP technique performed by extraperitoneal access (ELRP), when performed by a single surgeon, the results are even scarcer. Objective To analyze the early perioperative and oncologic results obtained with the ELRP, throughout the technical evolution of a single surgeon. Patients and methods A non-randomized retrospective study was held in a Brazilian hospital of reference. In the 5-year period, 115 patients underwent the ELRP procedure. Patients were divided into two groups, the first 57 cases (Group 1) and the following 58 cases, (Group 2). A comparative analysis between the groups of efficacy results and ELRP safety was carried out. Results The average age of patients was 62.8 year-old and the PSA of 6.9ng/dl. The total surgery time was 135.8 minutes on average, and the urethral-bladder anastomosis was 21.9 min (23.3 min versus 20.7 min). The positive surgical margins (PSM) rate was 17.1%, showing no difference between groups (16.4% versus 17.9%; p=0.835). There was statistical difference between the groups in relation to the anastomosis time, estimated blood loss and the withdrawal time of the urinary catheter. Conclusion The ELRP technique proved to be a safe and effective procedure in the treatment of prostate cancer, with low morbidity.

"Total reconstruction" of the urethrovesical anastomosis contributes to early urinary continence in laparoscopic radical prostatectomy

ABSTRACT Purpose: To demonstrate the effect of total reconstruction technique on postoperative urinary continence after laparoscopic radical prostatectomy (LRP). Material and Methods: LRP was performed using a standard urethrovesical anastomosis in 79 consecutive patients (Group-A) from June 2011 to October 2012, and a total reconstruction procedure in 82 consecutive patients (Group-B) from June 2012 to June 2013. The primary outcome measurement was urinary continence assessed at 1, 2, 4, 12, 24 and 52 weeks after catheter removal. Other data recorded were patient age, body mass index, International Prostate Symptoms Score, prostate volume, preoperative PSA, Gleason score, neurovascular bundle preservation, operation time, estimated blood loss, complications and pathology results. Results: In Group-A, the continence rates at 1, 2, 4, 12, 24 and 52 weeks were 7.59%, 20.25%, 37.97%, 58.22%, 81.01% and 89.87% respectively. In Group-B, the continence rates were 13.41%, 32.92%, 65.85%, 81.71%, 90.24% and 95.12% respectively. Group––B had significantly higher continence rates at 4 and 12 weeks after surgery (P<0.001 and P=0.001). There were no significant differences between the groups with respect to patient's age, body mass index, prostate-specific antigen level, prostate volume, IPSS, estimated blood loss, number of nerve-sparing procedures and postoperative complications. Conclusions: Total reconstruction technique in the procedure of urethrovesical anastomosis during LRP improved early recovery of continence.

Laparoscopic versus open radical prostatectomy in high prostate volume cases: impact on oncological and functional results

ABSTRACT Background and objective: To prospectively compare the laparoscopic versus open approach to RP in cases with high prostate volume and to evaluate a possible different impact of prostate volume. Materials and Methods: From March 2007 to March 2013 a total of 120 cases with clinically localized prostate cancer (PC) and a prostate volume>70cc identified for radical prostatectomy (RP), were prospectively analyzed in our institute. Patients were offered as surgical technique either an open retropubic or an intraperitoneal laparoscopic (LP) approach. In our population, 54 cases were submitted to LP and 66 to open RP. We analyzed the association of the surgical technique with perioperative, oncological and postoperative functional parameters. Results: In those high prostate volume cases, the surgical technique (laparoscopic versus open) does not represent a significant independent factor able to influence positive surgical margins rates and characteristics (p=0.4974). No significant differences (p>0.05) in the overall rates of positive margins was found, and also no differences following stratification according to the pathological stage and nerve sparing (NS) procedure. The surgical technique was able to significantly and independently influence the hospital stay, time of operation and blood loss (p<0.001). On the contrary, in our population, the surgical technique was not a significant factor influencing all pathological and 1-year oncological or functional outcomes (p>0.05). Conclusions: In our prospective non randomized analysis on high prostate volumes, the laparoscopic approach to RP is able to guarantee the same oncological and functional results of an open approach, maintaining the advantages in terms of perioperative outcomes.
