Abstract Introduction Prostatectomy is the standard treatment for patients with clinically localized prostate cancer. Currently, robot-assisted radical prostatectomy (RARP) is widely used for its advantages, as it provides better visualization, precision, and reduced tissue manipulation. However, RARP requires a multidisciplinary approach in which anesthesia and analgesia management are especially important. Objective This study aims to describe our experience delivering anesthesia for the first cases of patients undergoing RARP in a teaching hospital in Bogotá, Colombia. Methodology An observational study was conducted. We included all patients undergoing RARP from September 2015 to December 2019 at Fundación Santa Fe de Bogotá. All patients with incomplete data were excluded. Patient demographics were recorded, and significant perioperative events were reviewed. Results A total of 301 patients were included. At our institution, the mean age for patients undergoing RARP was 61.4 ± 6.7 years. The mean operative time was 205 ± 43 min and mean blood loss was 300 [200400] mL. Only 6 (2%) patients required transfusion. Age and BMI were not associated with clinical outcomes. Conclusions An adequate perioperative approach in RARP is important to minimize complications, which in this study and in this institution were infrequent.

Resumen Introducción La prostatectomía es el tratamiento estándar para pacientes con cáncer de próstata localizado. Actualmente, la prostatectomía radical asistida por robot es ampliamente utilizada por sus ventajas en visualización, precisión y manipulación de los tejidos. Sin embargo, este abordaje requiere un manejo multidisciplinario, pues el enfoque analgésico y anestésico es fundamental para optimizar los desenlaces. Objetivo Describir los primeros casos de prostatectomía radical asistida por robot realizadas en un hospital universitario de cuarto nivel en Bogotá, Colombia. Metodología Estudio observacional en el cual se incluyeron todos los pacientes sometidos a prostatectomía radical asistida por robot (PRAR) en el hospital Fundación Santa Fe de Bogotá entre septiembre de 2015 y diciembre de 2019. Se excluyeron los pacientes con historia clínica incompleta. Se registraron los datos demográficos y se revisaron los eventos perioperatorios importantes. Resultados Se analizaron 301 pacientes. La edad media de pacientes sometidos a PRAR fue 61,4 ± 6,7 años. El tiempo quirúrgico promedio fue 205 ± 43 minutos y la pérdida sanguínea media fue 300 [200-400] mL. Solo 6 pacientes (2 %) requirieron transfusión. La edad y el IMC no mostraron una asociación relevante con los desenlaces clínicos. Conclusiones El adecuado abordaje perioperatorio en PRAR es importante para minimizar las complicaciones, las cuales en este estudio y en esta institución fueron infrecuentes.

ABSTRACT BACKGROUND: Vesicourethral anastomotic stenosis (VUAS) following retropubic radical prostatectomy (RRP) significantly worsens quality of life. OBJECTIVES: To investigate the relationship between proliferative hypertrophic scar formation and VUAS, and predict more appropriate surgical intervention for preventing recurrent VUAS. DESIGN AND SETTING: Retrospective cross-sectional single-center study on data covering January 2009 to December 2019. METHODS: Among 573 male patients who underwent RRP due to prostate cancer, 80 with VUAS were included. They were divided into two groups according to VUAS treatment method: dilatation using Amplatz renal dilators (39 patients); or endoscopic bladder neck incision/resection (41 patients). The Vancouver scar scale (VSS) was used to evaluate the characteristics of scars that occurred for any reason before development of VUAS. RESULTS: Over a median follow-up of 72 months (range 12-105) after RRP, 17 patients (21.3%) had recurrence of VUAS. Although the treatment success rates were similar (79.5% versus 78.0%; P = 0.875), receiver operating characteristic (ROC) curve analysis indicated that dilatation using Amplatz dilators rather than endoscopic bladder neck incision/resection in patients with VSS scores 4, 5 and 6 may significantly reduce VUAS recurrence. A strong positive relationship was observed between VSS and total number of VUAS occurrences (r: 0.689; P < 0.001). VSS score (odds ratio, OR: 5.380; P < 0.001) and time until occurrence of VUAS (OR: 1.628; P = 0.008) were the most significant predictors for VUAS recurrence. CONCLUSIONS: VSS score can be used as a prediction tool for choosing more appropriate surgical intervention, for preventing recurrent VUAS.

ABSTRACT Prostate cancer is the most common invasive cancer in men. Radical prostatectomy (RP) is a definitive treatment option, but biochemical recurrence can reach 40%. Salvage lymphadenectomy is a relatively recent approach to oligometasis and has been rapidly diffused primarily due to improvement in imaging diagnosis and results showing possibly promising therapy. A systematic literature review was performed in March 2020, according to the PRISMA statement. We excluded studies with patients with suspicion or confirmation of visceral and / or bone metastases. A total of 27 articles were included in the study. All studies evaluated were single arm, and there were no randomized studies in the literature. A total of 1,714 patients received salvage lymphadenectomy after previous treatment for localized prostate cancer. RP was the most used initial therapeutic approach, and relapses were based on PET / CT diagnosis, with Coline-11C being the most widely used radiopharmaceutical. Biochemical response rates ranged from 0% to 80%. The 5 years - Free Survival Biochemical recurrence was analyzed in 16 studies with rates of 0% up to 56.1%. The articles do not present high levels of evidence to draw strong conclusions. However, even if significant rates of biochemical recurrence are not evident in all studies, therapy directed to lymph node metastases may present good oncological results and postpone the onset of systemic therapy. The long-term impact in overall survival and quality of life, as well as the best strategies for case selection remains to be determined.

ABSTRACT Purpose: Patient-reported history of pads per day (PPD) is widely recognized as a fundamental element of decision-making for anti-incontinence procedures. We hypothesize that SUI severity is often underestimated among men with moderate SUI. We sought to compare patient history of incontinence severity versus objective in-office physical examination findings. Materials and Methods: We retrospectively reviewed our single-surgeon male SUI surgical database from 2007-2019. We excluded patients with incomplete preoperative or postoperative data and those who reported either mild or severe SUI, thus having more straightforward surgical counseling. For men reported to have moderate SUI, we determined the frequency of upgrading SUI severity by recording the results of an in-office standing cough test (SCT) using the Male Stress Incontinence Grading Scale (MSIGS). The correlation of MSIGS with sling success rate was calculated. Failure was defined as >1 PPD usage or need for additional incontinence procedure. Results: Among 233 patients with reported moderate SUI (2-3 PPD), 89 (38%) had MSIGS 3-4 on SCT, indicating severe SUI. Among patients with 2-3 PPD preoperatively, sling success rates were significantly higher for patients with MSIGS 0-2 (76/116, 64%) compared to MSIGS 3-4 (6/18, 33%) (p <0.01). Conclusions: Many men with self-reported history of moderate SUI actually present severe SUI observed on SCT. The SCT is a useful tool to stratify moderate SUI patients to more accurately predict sling success.

Introduction: The world was surprised by COVID - 19 Pandemic, a viral infection caused by SARS-COV-2, which started in Wuhan, People's Republic of China, in December 2019. In addition to this new disease, the entire Brazil continued to deal with other diseases that have plagued our patients for decades. We present a case report of infection of the peritoneal cavity operative site that occurred at the beginning of the Pandemic by COVID-19 in Brazil. Case Report: patient who underwent radical prostatectomy, evolved with infection of the operative site 30 days after surgery, had a collection in the abdominal wall that was interconnected with pelvis cavity that could be drained with a wall drain. Discussion: The rate of infection of the operative site can reach up to 5% in radical prostatectomy surgeries, which is an acceptable rate. The beginning of the Pandemic in Brazil prevented the patients from returning to the big hospitals to some extent, either due to fear or uncertainty. Conclusion: We present a case of infection of the surgical site that coincided with the beginning of the Coronavirus Pandemic in Brazil that can be treated in a Basic Health Unit.

Introdução: O mundo foi surpreendido pela pandemia COVID-19, uma infecção viral causada pelo SARS-COV-2, iniciada em Wuhan, na República Popular da China, em dezembro de 2019. Além dessa nova doença, o Brasil inteiro continuou a lidar com outras doenças que atormentam nossos pacientes há décadas. Apresentamos um relato de caso de infecção do sítio operatório da cavidade peritoneal que ocorreu no início da Pandemia pelo COVID-19 no Brasil. Relato De Caso: paciente submetido a prostatectomia radical, evoluiu com infecção do sítio operatório 30 dias após a cirurgia, possuía coleção na parede abdominal e na pelve interconectadas entre si, que poderia ser drenada com dreno de parede. Discussão: A taxa de infecção do sítio operatório pode chegar a 5% em cirurgias de prostatectomia radical, que é uma taxa aceitável. O início da pandemia no Brasil impediu que os pacientes retornassem aos grandes hospitais, de certa forma, devido ao medo ou à incerteza. Conclusão: Apresentamos um caso de infecção do sítio cirúrgico que coincidiu com o início da pandemia de coronavírus no Brasil que pode ser tratada em uma unidade básica de saúde.

BACKGROUND@#Various prediction tools have been developed to predict biochemical recurrence (BCR) after radical prostatectomy (RP); however, few of the previous prediction tools used serum prostate-specific antigen (PSA) nadir after RP and maximum tumor diameter (MTD) at the same time. In this study, a nomogram incorporating MTD and PSA nadir was developed to predict BCR-free survival (BCRFS).@*METHODS@#A total of 337 patients who underwent RP between January 2010 and March 2017 were retrospectively enrolled in this study. The maximum diameter of the index lesion was measured on magnetic resonance imaging (MRI). Cox regression analysis was performed to evaluate independent predictors of BCR. A nomogram was subsequently developed for the prediction of BCRFS at 3 and 5 years after RP. Time-dependent receiver operating characteristic (ROC) curve and decision curve analyses were performed to identify the advantage of the new nomogram in comparison with the cancer of the prostate risk assessment post-surgical (CAPRA-S) score.@*RESULTS@#A novel nomogram was developed to predict BCR by including PSA nadir, MTD, Gleason score, surgical margin (SM), and seminal vesicle invasion (SVI), considering these variables were significantly associated with BCR in both univariate and multivariate analyses (P < 0.05). In addition, a basic model including Gleason score, SM, and SVI was developed and used as a control to assess the incremental predictive power of the new model. The concordance index of our model was slightly higher than CAPRA-S model (0.76 vs. 0.70, P = 0.02) and it was significantly higher than that of the basic model (0.76 vs. 0.66, P = 0.001). Time-dependent ROC curve and decision curve analyses also demonstrated the advantages of the new nomogram.@*CONCLUSIONS@#PSA nadir after RP and MTD based on MRI before surgery are independent predictors of BCR. By incorporating PSA nadir and MTD into the conventional predictive model, our newly developed nomogram significantly improved the accuracy in predicting BCRFS after RP.

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

Objective@#To assess the feasibility and validity of the establishment of a modified channel for extraperitoneal robot-assisted laparoscopic radical prostatectomy (RARP) through single incision.@*METHODS@#From November 2020 to January 2021, 35 cases of localized PCa were treated by extraperitoneal RARP through single incision in our center. All the operations were performed by the same surgeon, none via the multichannel port for the establishment of the channel. We recorded and analyzed the intra- and postoperative parameters, operation cost, complications, pathological findings and follow-up data.@*RESULTS@#All the operations were successfully completed, without conversion to open surgery or additional channels, or serious postoperative complications, the time for establishing the extraperitoneal space averaging 25.4 (20.0-45.0) min, the operation time 67.3 (35.0-125.0) min, intraoperative blood loss 75.5 (60.0-150.0) ml, time to first postoperative anal exhaust 26 (8-48) h, and postoperative hospital stay 7.89 (7-10) d. Postoperative pathology showed adenocarcinoma in all the cases, with Gleason score (GS) 3+3 in 9 (25.7%), GS 3+4 in 9 (25.7%), GS 4+3 in 8 (22.9%), and GS ≥ 8 in 9 (25.7%) of the cases, 23 (65.7%) in the

Objective@#To investigate the application of a simplified technique for reconstruction of vesicourethral support (RVUS) in laparoscopic radical prostatectomy (LRP).@*METHODS@#From January 2017 to August 2019, 122 patients with localized prostate cancer underwent extraperitoneal LRP, 65 with RVUS (the RVUS group) and 57 without RVUS (the non-RVUS group). We compared the operation time, intraoperative blood loss, rate of pelvic lymph node dissection, neurovascular bundle sparing, incidence of urethrovesical anastomotic urinary leakage (UVAUL), postoperative urinary continence, postoperative hospital stay, intraperitoneal drainage tube removal time, and urethral catheter removal time between the two groups of patients.@*RESULTS@#No statistically significant differences were observed between the two groups in the operation time, intraoperative blood loss, rate of pelvic lymph node dissection, neurovascular bundle sparing, or urethral catheter removal time (P > 0.05). The incidence rate of UVAUL was lower in the non-RVUS than in the RVUS group (8.8% vs 0%, P 0.05) and 12 months after catheter removal (87.7% vs 92.3%, P > 0.05). The postoperative hospital stay was dramatically longer in the non-RVUS than in the RVUS group ([9.1 ± 4.3] vs [6.7 ± 1.8] d, P < 0.01) and so was the intraperitoneal drainage tube removal time ([6.9 ± 4.5] vs [4.8 ± 1.5] d, P < 0.01).@*CONCLUSIONS@#The simplified technique for reconstruction of vesicourethral support in laparoscopic radical prostatectomy improves early urinary continence, especially immediate continence, decreases the incidence rate of urethrovesical anastomotic urinary leakage, and shortens the intraperitoneal drainage tube removal time and postoperative hospital stay.?

ABSTRACT A main challenge in the clinical management of prostate cancer is to identify which tumor is aggressive and needs invasive treatment. Thus, being able to predict which cancer will progress to biochemical recurrence is a great strategy to stratify prostate cancer patients. With that in mind, we created a mathematical formula that takes into account the patients clinical and pathological data resulting in a quantitative variable, called PSA density of the lesion, which has the potential to predict biochemical recurrence. To test if our variable is able to predict biochemical recurrence, we use a cohort of 219 prostate cancer patients, associating our new variable and classic parameters of prostate cancer with biochemical recurrence. Total PSA, lesion weight, volume and classic PSA density were positively associated with biochemical recurrence (p<0.05). ISUP score was also associated with biochemical recurrence in both biopsy and surgical specimen (p<0.001). The increase of PSA density of the lesion was significantly associated with the biochemical recurrence (p=0.03). Variables derived from the formula, PSA 15% and PSA 152, were also positive associated with the biochemical recurrence (p=0.01 and p=0.002 respectively). Logistic regression analysis shows that classic PSA density, PSA density of the lesion and total PSA, together, can explain up to 13% of cases of biochemical recurrence. PSA density of the lesion alone would have the ability to explain up to 7% of cases of biochemical recurrence. In conclusion, this new mathematical approach could be a useful tool to predict disease recurrence in prostate cancer.

RESUMO Um dos principais desafios no manejo clínico do câncer de próstata é identificar qual tumor é agressivo e precisa de tratamento invasivo. Assim, ser capaz de prever qual irá progredir para recorrência bioquímica é uma ótima estratégia para estratificar pacientes com câncer de próstata. Pensando nisso, criamos uma fórmula matemática que leva em consideração os dados clínicos e patológicos resultando em uma variável quantitativa, denominada densidade de PSA da lesão, que tem potencial para predizer recidiva bioquímica. Para testar se nossa variável é capaz de predizer recorrência bioquímica, usamos uma coorte de 219 pacientes com câncer de próstata, associando nossas variáveis e parâmetros clássicos como a recorrência bioquímica. PSA total, peso da lesão, volume e densidade de PSA clássico foram associados com recorrência bioquímica (p<0,05). O escore ISUP também foi associado à recorrência bioquímica na biópsia e na amostra cirúrgica (p<0,001). O aumento da densidade do PSA da lesão foi significativamente associado à recidiva bioquímica (p=0,03). As variáveis ??derivadas da fórmula, PSA 15% e PSA 152, também foram associadas positivamente à recorrência bioquímica (p=0,01 e p=0,002 respectivamente). A análise de regressão logística mostra que a densidade do PSA clássico, do PSA da lesão e PSA total, juntos, podem explicar até 13% dos casos de recorrência. A densidade de PSA da lesão por si só poderia explicar até 7% dos casos de recorrência. Em conclusão, esta nova abordagem matemática pode ser uma ferramenta útil para prever a recorrência da doença no câncer de próstata.

Abstract Background: The present study investigated the association between Postoperative Cognitive Dysfunction (POCD) and increased serum S100B level after Robotic-Assisted Laparoscopic Radical Prostatectomy (RALRP). Methods: The study included 82 consecutive patients who underwent RALRP. Serum S100B levels were determined preoperatively, after anesthesia induction, and at 30 minutes and 24 hours postoperatively. Cognitive function was assessed using neuropsychological testing preoperatively, and at 7 days and 3 months postoperatively. Results: Twenty four patients (29%) exhibited POCD 7 days after surgery, and 9 (11%) at 3 months after surgery. Serum S100B levels were significantly increased at postoperative 30 minutes and 24 hours in patients displaying POCD at postoperative 7 days (p = 0.0001 for both) and 3 months (p = 0.001 for both) compared to patients without POCD. Duration of anesthesia was also significantly longer in patients with POCD at 7 days and 3 months after surgery compared with patients without POCD (p = 0.012, p = 0.001, respectively), as was duration of Trendelenburg (p = 0.025, p = 0.002, respectively). Composite Z score in tests performed on day 7 were significantly correlated with duration of Trendelenburg and duration of anesthesia (p = 0.0001 for both). Conclusions: S100B increases after RALRP and this increase is associated with POCD development. Duration of Trendelenburg position and anesthesia contribute to the development of POCD. Trial Registry Number: (N° NCT03018522).

Resumo Introdução: O presente estudo investigou a associação entre Disfunção Cognitiva Pós-Operatória (DCPO) e aumento do nível sérico de S100B após Prostatectomia Radical Laparoscópica Assistida por Robô (PRLAR). Métodos: O estudo incluiu 82 pacientes consecutivos submetidos à PRLAR. Os níveis séricos de S100B foram determinados: no pré-operatório, após indução anestésica, e aos 30 minutos e 24 horas do pós-operatório. A função cognitiva foi avaliada com testes neuropsicológicos no pré-operatório, no 7° dia pós-operatório (7 DPO) e aos 3 meses após a cirurgia (3 MPO). Resultados: Observamos 24 pacientes (29%) com DCPO no 7 DPO e 9 pacientes com DCPO (11%) após 3 meses da cirurgia. Quando comparados com os pacientes sem DCPO, os níveis séricos de S100B estavam significantemente aumentados aos 30 minutos e às 24 horas do pós-operatório nos pacientes que apresentaram DCPO no 7 DPO (p= 0,0001 para os dois momentos) e 3 meses após a cirurgia (p= 0,001 para os dois momentos) A duração anestésica também foi significantemente maior em pacientes com DCPO no 7 DPO e 3 MPO em comparação com pacientes sem DCPO (p= 0,012, p= 0,001, respectivamente), assim como a duração da posição de Trendelenburg (p= 0,025, p= 0,002, respectivamente). O escore Z composto nos testes realizados no 7 DPO foi significantemente correlacionado com a duração da posição de Trendelenburg e a duração da anestesia (p= 0,0001 para ambos). Conclusão: S100B aumenta após PRLAR e o aumento está associado ao desenvolvimento de DCPO. A duração anestésica e o tempo decorrido em posição de Trendelenburg contribuem para o desenvolvimento de DCPO. Número de registro do estudo: (n° NCT03018522)

ABSTRACT Purpose: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. Materials and Methods: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. Results: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. Conclusions: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

O câncer de próstata é uma das neoplasias mais frequentes na população masculina. A prostatectomia radical está entre os principais tratamentos para essa afecção, sendo a primeira escolha para casos de doenças localizadas e localmente avançadas. Contudo, essa modalidade de tratamento cirúrgico costuma trazer grande prejuízo à função sexual masculina como um todo. Sabe-se que a disfunção erétil é uma complicação frequente e temida do tratamento cirúrgico do câncer de próstata, de forma que há diversas estratégias para prevenir e tratar tal condição. Porém, uma adequada reabilitação sexual desses pacientes envolve um atendimento global às dificuldades encontradas no restabelecimento de uma vida sexual satisfatória, não apenas focado na qualidade das ereções. Infelizmente, há uma série de problemas sexuais frequentes que são desencadeados pela prostatectomia radical, mas que ainda são extremamente negligenciados no cuidado pós-operatório. Dentre eles podemos citar: queda do desejo sexual, perda de volume peniano, desenvolvimento de deformidades penianas e distúrbios do orgasmo e da ejaculação. Neste artigo são abordados os principais efeitos sexuais da prostatectomia radical que costumam ser negligenciados no seguimento

ABSTRACT Objective: Minimally invasive techniques are used increasingly by virtue of advancements in technology. Surgery for prostate cancer, which has high morbidity, is performed with an increasing momentum based on the successful oncological and functional outcomes as well as cosmetic aspects. Materials and methods: Sixty two patients underwent robot-assisted perineal radical prostatectomy (R-PRP) surgery at our clinic between November 2016 and August 2017. Six pelvimetric dimensions were defined and measured by performing multiparametric magnetic resonance imaging (mpMRI) prior to operation in all patients. In light of these data, we aimed to investigate the effect of pelvimetric measurements on surgery duration and surgical margin positivity. Results: By using this technique in pelvic area, we observed that measurements only representing surgical site and excluding other pelvic organs had a significant effect on surgery duration, and pelvic dimensions had no significant effect on surgical margin positivity. Conclusion: In R-PRP technique, peroperative findings and oncological outcomes can vary depending on several variable factors, but although usually not taken into account, pelvimetric measurements can also affect these outcomes. However, there is a need for randomised controlled trials to be conducted with more patients.

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.

Resumen Objetivo El objetivo de este estudio fue analizar las experiencias y expectativas de pacientes sometidos a prostatectomía radical sin conservación de bandeletas neurovasculares. 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.
