Purpose: The impact of pelvic floor muscle training on the recovery of urinary continence after radical prostatectomy is still controversial. We tested the effectiveness of biofeedback-pelvic floor muscle training in improving urinary incontinence in the 12 months following radical prostatectomy. Materials and Methods: A total of 73 patients who underwent radical prostatectomy were randomized to a treatment group (36) receiving biofeedback-pelvic floor muscle training once a week for 3 months as well as home exercises or a control group (37). Patients were evaluated 1, 3, 6 and 12 months postoperatively. Continence was defined as the use of 1 pad or less daily and incontinence severity was measured by the 24-hour pad test. Incontinence symptoms and quality of life were assessed with the International Continence Society male Short Form questionnaire and the Incontinence Impact Questionnaire. Pelvic floor muscle strength was evaluated with the Oxford score. Results: A total of 54 patients (26 pelvic floor muscle training and 28 controls) completed the trial. Duration of incontinence was shorter in the treatment group. At postoperative month 12, 25 (96.15%) patients in the treatment group and 21 (75.0%) in the control group were continent (p = 0.028). The absolute risk reduction was 21.2% (95% CI 3.45-38.81) and the relative risk of recovering continence was 1.28 (95% CI 1.02-1.69). The number needed to treat was 5 (95% CI 2.6-28.6). Overall there were significant changes in both groups in terms of incontinence symptoms...

Purpose: We evaluated the somatic and autonomic innervation of the pelvic floor and rhabdosphincter before and after nerve sparing radical retropubic prostatectomy using neurophysiological tests and correlated findings with clinical parameters and urinary continence. Materials and Methods: From February 2003 to October 2005, 46 patients with prostate cancer were enrolled in a controlled, prospective study. Patients were evaluated before and 6 months after nerve sparing radical retropubic prostatectomy using the UCLA-PCI urinary function domain and neurophysiological tests, including somatosensory evoked potential, and the pudendo-urethral, pudendo-anal and urethro-anal reflexes. Clinical parameters and urinary continence were correlated with afferent and efferent innervation of the membranous urethra and pelvic floor. We used strict criteria to define urinary continence as complete dryness with no leakage at all, not requiring any pads or diapers and with a UCLA-PCI score of 500. Patients with a sporadic drop of leakage, requiring up to 1 pad daily, were defined as having occasional urinary leakage. Results: Two patients were excluded from study due to urethral stricture postoperatively. We evaluated 44 patients within 6 months after surgery. The pudendo-anal and pudendo-urethral reflexes were unchanged postoperatively (p = 0.93 and 0.09...

Background: Posterior reconstruction (PR) of the rhabdosphincter has been previously described during retropubic radical prostatectomy, and shorter times to return of urinary continence were reported using this technical modification. This technique has also been applied during robot-assisted radical prostatectomy (RARP); however, contradictory results have been reported. Objective: We describe here a modified technique for PR of the rhabdosphincter during RARP and report its impact on early recovery of urinary continence and on cystographic leakage rates. Design, setting, and participants: We analyzed 803 consecutive patients who underwent RARP by a single surgeon over a 12-mo period: 330 without performing PR and 473 with PR. Surgical procedure: The reconstruction was performed using two 6-in 3-0 Poliglecaprone sutures tied together. The free edge of the remaining Denonvillier`s fascia was identified after prostatectomy and approximated to the posterior aspect of the rhabdosphincter and the posterior median raphe using one arm of the continuous suture. The second layer of the reconstruction was then performed with the other arm of the suture, approximating the posterior lip of the bladder neck and vesicoprostatic muscle to the posterior urethral edge. Measurements: Continence rates were assessed with a self-administrated...

Introdução: A hiperplasia prostática benigna (HPB), uma das doenças mais comuns do homem idoso, pode estar associada com sintomas do trato urinário inferior que afetam sua qualidade de vida. A prostatectomia aberta é uma das opções de tratamento. O antígeno prostático específico (PSA) pode estar aumentado em pacientes com HPB, reduzindo sua especificidade diagnóstica para câncer de próstata. O objetivo do estudo é avaliar o comportamento do PSA após a prostatectomia aberta, particularmente, em pacientes com o exame aumentado no pré-operatório. Método: Foi realizado um estudo prospectivo com 130 pacientes submetidos à prostatectomia aberta no HCFMUSP de julho de 2000 a setembro de 2003. Os pacientes foram divididos em dois grupos de estudo. O grupo caso foi composto por pacientes com PSA > = 4,0ng/ml e o grupo controle formado por pacientes com PSA < 4,0ng/ml. Após seis a doze meses das operações foram realizados exame digital retal e PSA. Os pacientes com exame digital retal anormal ou PSA após a prostatectomia > = 4,0ng/ml ou queda percentual do PSA < 70% do valor inicial foram biopsiados. Resultados: Em média, os pacientes apresentaram 71,18 anos e 10,81ng/ml de nível sérico de PSA total. O tamanho da próstata e o peso do adenoma foram...

Introdução: A prostatectomia perineal tem sido proposta como um procedimento seguro e pouco invasivo, sem comprometer os princípios oncológicos. No entanto, este acesso tem sido questionado sobre o risco de promover a incontinência anal. Objetivo: avaliar os efeitos do acesso para a prostatectomia perineal no mecanismo de continência anal. Métodos: Trinta e um pacientes com indicação cirúrgica de prostatectomia perineal foram avaliados entre agosto de 2008 e maio de 2009. Dados do pré e pós operatório (8 meses): estadiamento do câncer de próstata, a avaliação clínica (Índice de incontinência anal da Cleveland Clinic - CCISS), índice de qualidade de vida na incontinência anal (FIQL) e manometria anorretal. Os parâmetros médios manométricos foram: pressão de repouso (RP / mmHg), pressão de contração voluntária máxima (MSP / mmHg), zona de alta pressão (ZAP / cm), índice de fadiga do esfíncter (SFI / min.), índice de assimetria esfincteriana (SAI /%), limiar de sensibilidade retal (RST / ml) e volume retal máximo tolerado (MTRV / ml). Resultados: Foi concluída a avaliação em vinte e três pacientes, com média de idade de 65 (54-72) anos. Pré-operatório: o peso médio da próstata foi de 34,5 (24-54) gramas...

INTRODUÇÃO: O câncer de próstata (CaP) é o tipo mais comum entre os tumores malignos que afetam o homem. Dentre as opções terapêuticas para o tratamento precoce do CaP, destaca-se o tratamento cirúrgico com resultados satisfatórios de até 94% de cura nos casos localizados. A ressecção cirúrgica do CaP pode ser feita por três abordagens principais: prostatectomia radical retropúbica (PRR), prostatectomia radical laparoscópica (PRL) e mais recentemente a prostatectomia radical laparoscópica robô assistida (PRAR). Uma vez que existem várias alternativas terapêuticas para esse tipo de câncer, a qualidade de vida e satisfação relacionadas à avaliação, tornam-se muito importantes nos diferentes tipos de técnicas cirúrgicas. OBJETIVO: Comparar a qualidade de vida e o índice de satisfação nos pacientes submetidos a PRR e PRAR através de um estudo prospectivo e aleatorizado. MATERIAL E MÉTODOS: Através do Sistema Único de Saúde (SUS), 200 pacientes com diagnóstico de adenocarcinoma de próstata localizado, foram selecionados de forma aleatória para participarem do estudo, sendo então encaminhados entre março de 2010 a janeiro de 2011 para o Hospital Alemão Oswaldo Cruz (HAOC) para realizar PRAR, ou para o Instituto do Câncer do Estado de São Paulo (ICESP)...

Introdução: margem cirúrgica comprometida ou positiva é definida como tumor estendendo-se na superfície de corte do cirurgião. A porcentagem deste evento, resultante de incisão capsular, varia de 1,3 a 71 % (EPSTEIN, 2001). O objetivo deste estudo é comparar o comprometimento das margens cirúrgicas nas prostatectomias radicais realizadas por via retropúbica e laparoscópica, em dois serviços de referência no Brasil. Pacientes e Métodos: foram analisados os exames anátomo-patológjcos de 179 pacientes submetidos a prostatecomia radical por adenocarcinoma de próstata, 89 por via retropúbica e 90 por via laparoscópica. Critérios de inclusão: pacientes com PSA (antígeno específico da próstata) igual ou menor que 15 ng/ml (nanogramas por mililitro) e Gleason igual ou menor que 7 na biópsia prostática, estádio clínico máximo T2. Resultados: houve comprometimento de margem cirúrgica em 41,57 % dos pacientes submetidos à PRR (prostatectomia radical retropúbica), distribuídos da seguinte maneira: 34,21 % nos estádios pT2 (7,69 % no pT2a, zero no pT2b e 40,98 % no pT2c) e 84,61% nos estádios pT3 (77,77 % no pT3a e 100 % no pT3b). Nos pacientes submetidos a PRL (prostatectomia radical laparoscópica) houve margens cirúrgicas positivas em 24...

O adenocarcinoma de próstata é a segunda neoplasia maligna que afeta homens, sendo precedida somente pelo cancer de pele. A prostatectomia radical continua sendo a mais aceita estratégia terapêutica para os casos confinado a próstata. Alguns achados clinicopatológicos em pacientes submetidos a prostatectomia radical são controvertidos como tendo valor preditivo de progressão bioquímica pós-cirurgia. O monitoramento da progressão da moléstia pós-prostatectomia radical é feito através de dosagem do PSA sérico cujo aumento pode significar recidiva local e/ou metástases. O valor de corte do PSA sérico indicando progressão é variável entre os autores. Há uma recomendação recente da Associação Americana de Urologia para que este valor seja ?0,2ng/mL com um segundo valor >0,2ng/mL. Não está estabelecido se pacientes mais jovens ou de raça negra mostram taxa de recidiva bioquímica maior. O PSA pré-operatório é um dado de grande importância preditiva, mas não está estabelecido a validade da estratificação dos valores em 3 categorias: 4-10ng/mL, 10-20ng/mL e >20ng/mL. Margens cirúrgicas comprometidas no espécime cirúrgico estão na categoria I (valor preditivo comprovado). É controvertido se a contagem final de Gleason 3+4=7 é semelhante ou não a 4+3=7 como fator preditivo de progressão bioquímica pós-prostatectomia radical. O estudo foi retrospectivo e os dados foram coletados dos prontuários médicos de 300 pacientes submetidos consecutivamente à prostatectomia radical no Hospital de Clínicas da Universidade Estadual de Campinas...

CONTEXT: Despite the recent improvements in performing radical retropubic prostatectomy that have led to a considerable decrease in the complication rate, erectile dysfunction still represents a major problem. Moreover, less invasive treatment options that are emerging for erectile dysfunction have not shown satisfactory results in managing these patients. OBJECTIVE: To study the efficacy and side effects of self-injection therapy in the treatment of men who had become impotent after undergoing radical prostatectomy due to prostate cancer, over a study period of 96 months. DESIGN: Observational study. SETTING: University Referral Center. PARTICIPANTS: 168 patients with erectile dysfunction, aged 43 to 78 years old, who underwent radical retropubic prostatectomy due to localized prostate cancer. PROCEDURES: The patients were treated with self-injection therapy using papaverine, phentolamine and prostaglandin E1, at home. RESULTS: This study showed an acceptable 94.6% success rate, with no life-threatening complications. In addition to this, our series presented a 13.1% cure rate with this therapy. CONCLUSION: Self-injection therapy with papaverine, phentolamine and prostaglandin E1 is effective and safe in the treatment of erectile dysfunction after radical prostatectomy.

Radical prostatectomy continues to play a central role in the management of localized prostate cancer. The majority of patients diagnosed with prostate cancer will undergo radical prostatectomy. A decrease in the morbidity of this surgical procedure has been accomplished through an improved understanding of pelvic anatomy and a greater understanding of the natural history of prostate cancer. Recently, minimally invasive techniques have been applied to radical prostatectomy (laparoscopic prostatectomy) in order to further decrease the morbidity of this operation. What remains to be determined is whether this approach confers the same long term surgical outcomes as the open approach. One method which offers known long term outcomes coupled with decreased morbidity is the radical perineal prostatectomy. The purpose of this paper is to review the criteria for patient selection as well as outcomes of the radical perineal prostatectomy.

PURPOSE: We describe the critical steps of the laparoscopic radical prostatectomy (LRP) technique and discuss how they impact upon the pertinent issues regarding prostate cancer surgery: blood loss, potency and continence. RESULTS: A major advantage of LRP is the reduced operative blood loss. The precise placement of the dorsal vein complex stitch associated with the tamponading effect of the CO2 pneumoperitoneum significantly decrease venous bleeding, which is the main source of blood loss during radical prostatectomy. At the Cleveland Clinic, the average blood loss of our first 100 patients was 322.5 ml, resulting in low transfusion rates. The continuous venous bleeding narrowed pelvic surgical field and poor visibility can adversely impact on nerve preservation during open radical prostatectomy. Laparoscopy, with its enhanced and magnified vision in a relatively bloodless field allows for excellent identification and handling of the neurovascular bundles. During open retropubic radical prostatectomy, the pubic bone may impair visibility and access to the urethral stump, and the surgeon must tie the knots relying on tactile sensation alone. Consequently, open prostatectomy is associated with a prolonged catheterization period of 2 - 3 weeks. Comparatively...

PURPOSE: To compare the perioperative, short-term and long-term postoperative results of radical retropubic prostatectomy (RRP), laparoscopic radical prostatectomy (LRP) and robotic assisted laparoscopic prostatectomy (RALP) in the most recent studies evaluable. MATERIALS AND METHODS: Using PubMed we have undertaken a search based on references from major and recent articles with considerable sample sizes. RESULTS: The operative blood loss and the risk of transfusion were lower in the laparoscopic and robotic-assisted approaches. The surgical duration was shorter in the open and robotic group. Regarding the positive margins, continence and potency no substantial differences between the RRP, LRP, and RALP were found. CONCLUSIONS: Our results suggest that no one surgical approach is superior in terms of functional and early oncologic outcomes. Potential advantages of any surgical approach have to be confirmed through longer-term follow-up and adequately designed clinical studies.

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.

OBJECTIVE: Perineal prostatectomy has been proposed as a less invasive and safe procedure, but the risk of anal incontinence has been studied. This study aimed to evaluate the effects of perineal access on anal continence mechanisms after perineal prostatectomy. METHODS: From August 2008 to May 2009, twenty three patients underwent perineal prostatectomy. These patients were evaluated before surgery and eight months postoperatively using the Cleveland Clinic Anal Incontinence Score, the Fecal Incontinence Quality of Life Score, and anorectal manometry. RESULTS: The mean age of the subjects was 65 (range, 54-72) years, and the mean prostate weight was 34.5 (range, 24-54) grams. Gleason scores ranged from 6-7, and the mean Cleveland Clinic Anal Incontinence Score (mean±;standard deviation) values were 0.9±1.9 and 0.7±1.2 (p.0.05) before and after surgery, respectively. The Fecal Incontinence Quality of Life Score did not change significantly after surgery. The mean values for anal manometric parameters before and after surgery were, respectively: Resting Pressures of 64±23 mmHg and 65±17 mmHg (p = 0.763), Maximum Squeezing Pressures of 130±41 mmHg and 117±40 mmHg (p = 0.259), High Pressure Zones of 3.0±0.9 cm and 2.7±0.8 cm(p = 0.398)...

Purpose: We compared the safety and efficacy of laparoscopic and open radical prostatectomy through a systematic assessment of the literature. Materials and Methods: Literature databases were searched from 1996 to December 2004 inclusive. Studies comparing transperitoneal laparoscopic radical prostatectomy, extraperitoneal endoscopic radical prostatectomy or robot assisted radical prostatectomy with open radical retropubic prostatectomy or radical perineal prostatectomy for localized prostate cancer were included. Comparisons between different laparoscopic approaches were also included. Results: We identified 30 comparative studies, of which none were randomized controlled trials. There were 21 studies comparing laparoscopic with open prostatectomy with a total of 2,301 and 1,757 patients, respectively, and 9 comparing different laparoscopic approaches with a total of 1,148 patients. In terms of safety there did not appear to be any important differences in the complication rate between laparoscopic and open approaches. However, blood loss and transfusions were lower for laparoscopic approaches. In terms of efficacy operative time was longer for laparoscopic than for open prostatectomy but length of stay and duration of catheterization were shorter. Positive margin rates and recurrence-free survival were similar. Continence and potency were not well reported but they appeared similar for the 2 approaches. There were no important differences between laparoscopic approaches. Conclusions: Laparoscopic radical prostatectomy is emerging as an alternative to open radical prostatectomy but randomized...

Background and objectives:Although many features of robotic prostatectomy are similar to those of conventional laparoscopic urological procedures (such as laparoscopic prostatectomy), the procedure is associated with some drawbacks, which include limited intravenous access, relatively long operating time, deep Trendelenburg position, and high intra-abdominal pressure. The primary aim was to describe respiratory and hemodynamic challenges and the complications related to high intra-abdominal pressure and the deep Trendelenburg position in robotic prostatectomy patients. The secondary aim was to reveal safe discharge criteria from the operating room.Methods:Fifty-three patients who underwent robotic prostatectomy between December 2009 and January 2011 were prospectively enrolled. Main outcome measures were non-invasive monitoring, invasive monitoring and blood gas analysis performed at supine (T0), Trendelenburg (T1), Trendelenburg + pneumoperitoneum (T2), Trendelenburg-before desufflation (T3), Trendelenburg (after desufflation) (T4), and supine (T5) positions.Results:Fifty-three robotic prostatectomy patients were included in the study. The main clinical challenge in our study group was the choice of ventilation strategy to manage respiratory acidosis...

PURPOSE: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view. MATERIALS AND METHODS: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP) and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy. RESULTS: LRP nuances were reassessed by surgical teams in order to verify possible weaknesses in their performance. Our basic approach was to carefully study the anatomy and pioneer open surgery descriptions in order to standardized and master a technique. The learning curve is presented in terms of an objective evaluation of outcomes for cancer control and functional results. In terms of technique-outcomes, there are several key elements in radical prostatectomy, such as dorsal vein control-apex exposure and nerve sparing with particular implications in oncological and functional results. Major variations among the surgical teams' performance and follow-up prevented objective comparisons in radical prostatectomy. The remarkable evolution of LRP needs to be supported by comprehensive results. CONCLUSIONS: Radical prostatectomy is a complex surgical operation with difficult objectives. Surgical technique should be standardized in order to allow an adequate and reliable performance in all settings...

OBJECTIVE: Perineal prostatectomy has been proposed as a less invasive and safe procedure, but the risk of anal incontinence has been studied. This study aimed to evaluate the effects of perineal access on anal continence mechanisms after perineal prostatectomy. METHODS: From August 2008 to May 2009, twenty three patients underwent perineal prostatectomy. These patients were evaluated before surgery and eight months postoperatively using the Cleveland Clinic Anal Incontinence Score, the Fecal Incontinence Quality of Life Score, and anorectal manometry. RESULTS: The mean age of the subjects was 65 (range, 54-72) years, and the mean prostate weight was 34.5 (range, 24-54) grams. Gleason scores ranged from 6-7, and the mean Cleveland Clinic Anal Incontinence Score (mean±;standard deviation) values were 0.9±1.9 and 0.7±1.2 (p.0.05) before and after surgery, respectively. The Fecal Incontinence Quality of Life Score did not change significantly after surgery. The mean values for anal manometric parameters before and after surgery were, respectively: Resting Pressures of 64±23 mmHg and 65±17 mmHg (p = 0.763), Maximum Squeezing Pressures of 130±41 mmHg and 117±40 mmHg (p = 0.259), High Pressure Zones of 3.0±0.9 cm and 2.7±0.8 cm(p = 0.398)...
