RESUMO

OBJECTIVES: To evaluate the safety and effectiveness of robot-assisted radical cystectomy (RARC), laparoscopic radical cystectomy (LRC), and open radical cystectomy (ORC) in bladder cancer. METHODS: A literature search for network meta-analysis was conducted using international databases up to February 29, 2024. Outcomes of interest included baseline characteristics, perioperative outcomes and oncological outcomes. RESULTS: Forty articles were finally selected for inclusion in the network meta-analysis. Both LRC and RARC were associated with longer operative time, smaller amount of estimated blood loss, lower transfusion rate, shorter time to regular diet, fewer incidences of complications, and fewer positive surgical margin compared to ORC. LRC had a shorter time to flatus than ORC, while no difference between RARC and ORC was observed. Considering lymph node yield, there were no differences among LRC, RARC and ORC. In addition, there were statistically significant lower transfusion rates (OR=-0.15, 95% CI=-0.47 to 0.17), fewer overall complication rates (OR=-0.39, 95% CI=-0.79 to 0.00), fewer minor complication rates (OR=-0.23, 95% CI=-0.48 to 0.02), fewer major complication rates (OR=-0.23, 95% CI=-0.68 to 0.21), fewer positive surgical margin rates (OR=0.22, 95% CI=-0.27 to 0.68) in RARC group compared with LRC group. CONCLUSION: LRC and RARC could be considered as a feasible and safe alternative to ORC for bladder cancer. Notably, compared with LRC, RARC may benefit from significantly lower transfusion rates, fewer complications and lower positive surgical margin rates. These data thus showed that RARC might improve the management of patients with muscle invasive or high-risk non-muscle invasive bladder cancer.

RESUMO

OBJECTIVE: To describe the trocar disposition, docking angles, surgical times, functional outcomes, and complications experienced during the first 30 surgeries with Hugo RAS platform performed by a high-volume Da Vinci Xi's surgeon. METHODS: Retrospective, observational, descriptive study was performed between May-December 2023. Safety and feasibility of the procedures were evaluated considering console and docking time (minutes), perioperative complications (Clavien-Dindo classification), blood loss (mL), and collision of the arms during the procedures (Yes/No). For radical prostatectomies (RARP) the urinary continence and sexual function were also evaluated. RESULTS: RARP, simple prostatectomies (RASP), partial nephrectomies (RAPN), and cystectomy (RARC) were performed. Trocar placement, docking, and bed assistant ergonomics were important challenges. Patient positioning, trocar placement, and robotic arm positioning had to be adapted. The median console operative time for RARP and RASP was 78 (60-120) minutes and 79 (58-125) minutes, respectively. The median docking time for both RARP and RASP was 10 (5-20) minutes. Of patients undergoing RARP, 94.5% recovered sexual function and no patient used more than one PAD per day after 90days of the surgery. The median console operative and docking time for RAPN was 82 (80-130) minutes and 12 (7-19) minutes, respectively. Blood loss in all patients was less than 200 mL and all none procedure presented major complications. CONCLUSION: For a high-volume surgeon with motivated and well-trained multidisciplinary team, the implementation of HUGO RAS system for urological program is safe and smooth. Adaptations were necessary to achieve equivalent surgical technique and results. Docking position and bed assistant ergonomics are the major challenges.

RESUMO

INTRODUCTION: The increasing adoption of robotic-assisted cystectomy with intracorporeal urinary diversion (ICUD), despite its complexity, prompts a detailed comparison with extracorporeal urinary diversion (ECUD). Our study at a single institution investigates perioperative outcomes and identifies risk factors impacting the success of these surgical approaches. METHODS: In this retrospective analysis, 174 patients who underwent robotic-assisted cystectomy at the University of Louisville from June 2016 to August 2021 were reviewed. The cohort was divided into two groups based on the urinary diversion method: 30 patients underwent ECUD and 144 underwent ICUD. Data on demographics, complication rates, length of hospital stay, and readmission rates were meticulously collected and analyzed. RESULTS: Operative times were comparable between the ICUD and ECUD groups. However, the ICUD group had a significantly lower intraoperative transfusion rate (0.5 vs. 1.0, p=0.02) and shorter hospital stay (7.8 vs. 12.3 days, p<0.001). Factors such as male sex, smoking history, diabetes mellitus, intravesical therapy, higher ASA, and ACCI scores were associated with increased Clavien-Dindo Grade 3 or higher complications. Age over 70 was the sole factor linked to a higher 90-day readmission rate, with no specific characteristics influencing the 30-day rate. CONCLUSION: Robotic cystectomy with ICUD results in shorter hospitalizations and lower intraoperative transfusion rates compared to ECUD, without differences in operative time, high-grade postoperative complications, or readmission rates. These findings can inform clinical decision-making, highlighting ICUD as a potentially more favorable option in appropriate settings.

RESUMO

OBJECTIVE: Wound dehiscence is associated with high morbidity and mortality. This study aimed to analyze the risk factors and comorbidities in the patients undergoing radical cystectomy with early postoperative wound dehiscence. METHODS: In all, 539 patients with bladder cancer who underwent radical cystectomy and urinary diversion at a single center between January 2008 and January 2022 were included in the study. The data related to the demographics, medical history, and perioperative clinical features were reviewed. Univariate and multivariate regression analysis was performed to identify risk factors for wound dehiscence. RESULTS: The mean age of the patients was 64.2 years (22-91). The mean body mass index was 26.4 kg/m2 (18.7-35.4). Wound dehiscence was observed in 43 (7.9%) of 539 patients. The patients with wound dehiscence had significantly higher mean BMI (27.8 vs. 26.3, p=0.006), ASA scores (p=0.002), history of chronic obstructive pulmonary disease (30.2 vs. 14.3%, p=0.006), diabetes mellitus (44.2 vs. 17.9%, p=0.003), previous abdominal surgery (18.6 vs. 7.7%, p=0.014), and postoperative ileus (58.1 vs. 16.9%, p=0.006). In the multivariable regression model, diabetes mellitus (odds ratio [OR] 4.9, 95%CI 2.3-10.1; p<0.001), postoperative ileus (OR 8.1, 95%CI 4.1-16.5; p<0.001), and chronic obstructive pulmonary disease (OR 2.6, 95%CI 1.2-5.7; p=0.013) were independent predictors of abdominal wound dehiscence following radical cystectomy. CONCLUSION: Diabetes mellitus, chronic obstructive pulmonary disease, and postoperative ileus were strongly associated with abdominal wound dehiscence following radical cystectomy. Both potential preventive and therapeutic interventions may decrease the risk of wound dehiscence.

RESUMO

ABSTRACT Purpose: A systematic review of the literature with available published literature to compare ileal conduit (IC) and cutaneous ureterostomy (CU) urinary diversions (UD) in terms of perioperative, functional, and oncological outcomes of high-risk elderly patients treated with radical cystectomy (RC). Protocol Registration: PROSPERO ID CRD42020168851. Materials and Methods: A systematic review, according to the PRISMA Statement, was performed. Search through the Medline, Embase, Scopus, Scielo, Lilacs, and Cochrane Database until July 2020. Results: The literature search yielded 2,883 citations and were selected eight studies, including 1096 patients. A total of 707 patients underwent IC and 389 CU. Surgical procedures and outcomes, complications, mortality, and quality of life were analyzed. Conclusions: CU seems to be a safe alternative for the elderly and more frail patients. It is associated with faster surgery, less blood loss, lower transfusion rates, a lower necessity of intensive care, and shorter hospital stay. According to most studies, complications are less frequent after CU, even though mortality rates are similar. Studies with long-term follow up are awaited.

RESUMO

ABSTRACT Objective: To characterize the contribution of the extirpative and reconstructive portions of radical cystectomy (RC) to complications rates, and assess differences between urinary diversion (UD) types. Materials and Methods: We conducted a retrospective cohort study comparing patients undergoing UD alone or RC+UD for bladder cancer from 2006 to 2017 using ACS National Surgical Quality Improvement Program database. The primary outcome was major complications, while secondary outcomes included minor complications and prolonged length of stay. Propensity score matching (PSM) was utilized to assess the association between surgical procedure (UD alone or RC+UD) and outcomes, stratified by diversion type. Lastly, we examined differences in complication rates between ileal conduit (IC) vs. continent UD (CUD). Results: When comparing RC + IC and IC alone, PSM yielded 424 pairs. IC alone had a lower risk of any complication (HR 0.63, 95% CI 0.52-0.75), venous thromboembolism (HR 0.45, 95% CI 0.22-0.91) and bleeding needing transfusion (HR 0.41, 95% CI 0.32-0.52). This trend was also noted when comparing RC + CUD to CUD alone. CUD had higher risk of complications than IC, both with (56.6% vs 52.3%, p = 0.031) and without RC (47.8% vs 35.1%, p=0.062), and a higher risk of infectious complications, both with (30.5% vs 22.7%, p<0.001) and without RC (34.0% vs 22.0%, p=0.032). Conclusions: RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, CUD had a higher risk of post-operative complication than IC.

RESUMO

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

RESUMO

Resumen Objetivo: Describir resultados en términos de morbilidad y mortalidad del tratamiento de quistes hidatídicos hepáticos (QHH) por vía laparoscópica en una serie de pacientes consecutivos. Comparar calidad de vida (CV) de pacientes sometidos a quistectomía laparoscópica (QL) con pacientes llevados a colecistectomía laparoscópica. Materiales y Método: Serie de casos con seguimiento de pacientes con QHH, sometidos a QL. Analizamos datos con Stata® 10.0, mediante medidas de tendencia central y dispersión. Describimos 4 variables, realizando seguimiento con tomografía computada (TC) abdominal. Aplicamos encuesta de calidad de vida SF-36. Resultados: Incluimos 12 pacientes, 58,3% de género femenino. Número de quistes 2,02 ± 1,56, volumen quístico mayor 809,16 ± 766,05 ml, diámetro de quiste mayor 11,77 ± 4,33 cm, predominando en lóbulo hepático derecho (58%). Tiempo operatorio promedio 234,1 ± 52,9 minutos. Estadía hospitalaria promedio 11,5 ± 14,5 días. Morbilidad en 16,6%, sin mortalidad posoperatoria. Seguimiento con imágenes promedio fue 7,9 ± 4,3 meses, encontrando cavidades residuales pequeñas y asintomáticas en 50% de pacientes. No reportamos recidivas. Al comparar CV con grupo de colecistectomía sólo encontramos diferencia respecto a vitalidad (p = 0,04). Discusión: Aunque nuestra serie es pequeña y presenta mayor tiempo quirúrgico (por selección de pacientes) y mayor estancia hospitalaria que en otras series de QL, presenta menor porcentaje de recidivas, de fístulas biliares y no presenta mortalidad, concordando con otras series de QL que la recomiendan como opción terapéutica. Conclusiones: La QL para el tratamiento de los QHH resulta una cirugía aceptable, con morbilidad y mortalidad comparable con reportes de cirugía abierta.


Aim: To describe results in morbidity and mortality terms of the hepatic hydatidosis (HHC) treatment by laparoscopic route in selected patients. In addition, compare the quality of life (QL) of cystomectized vs cholecystectomized patients, both laparoscopically. Materials and Method: Case series with follow-up of patients with HHC, undergoing laparoscopic cystectomy (LC). Data analysis, through measures of central tendency and dispersion, performed with Stata® 10.0. Analyzing 4 variables followed-up with abdominal computed tomography. A quality of life survey SF-36" was applied. Results: 12 patients were included, 58.3% female gender. Cysts number 2.02 ± 1.56, largest cystic volume 809.16 ± 766.05 ml, larger cyst diameter 11,77 ± 4,33 cm. Right hepatic lobe is predominantly 58%. Surgical time, 234.16 ± 52.95 minutes. Hospital stay, 11.58 ± 14.55 days. Morbidity 16.6%, with no postoperative mortality. Follow-up, performed at 7.9 ± 4.3 months, finding residual cavity in 50%, no recurrences were reported. At comparing QL with cholecystectomy group, we only found differences at the vitality item (p = 0,04). Discussion: Although our series is small and has a longer surgical time (by patient selection) and a longer hospital stay than in other LC series, it has a lower recurrences percentage, biliary fistulas, and no mortality, agreeing with other LC series that recommend it as a therapeutic option. Conclusions: The laparoscopic approach for the HHC treatment, is an acceptable surgery, with morbidity and mortality comparable to the reports of laparotomy surgery.

RESUMO

ABSTRACT Introduction: Neobladder vaginal fistula (NVF) is a known complication after cystectomy and orthotopic diversion in women, occurring in 3-5% of women. Possible risk factors for fistula formation include compromised tissue vascularity due to surgical dissection and/or radiotherapy, suture line proximity, local tissue recurrence, and injury to the vaginal wall during dissection. The surgical repair of a NVF can be challenging secondary to vaginal shortening, atrophy, local inflammation from chronic exposure to urinary leakage, and the proximity of the neobladder to the anterior vaginal wall. In this video, we present transvaginal repair of a NVF with Martius flap interposition. Materials and Methods: This is the case of a 47 year old woman with a history of radical cystectomy and creation of a Studer pouch secondary to bladder cancer two years prior who subsequently developed a NVF. Evaluation included an office cystoscopy which demonstrated a 3-4mm left-sided neobladder vaginal fistula at the level of the ileal-urethral anastomosis. No pelvic organ prolapse or evidence of bladder cancer recurrence was appreciated. Results: A vaginal approach for the NVF repair was performed with a Martius flap interposition. A water-tight closure was achieved without any intraoperative or immediate postoperative complications. The urethral Foley was removed at 2 weeks and by 4 weeks the patient did not report any urinary leakage. Conclusions: Neobladder vaginal fistula is a rare complication following cystectomy and orthotopic urinary diversion that can be repaired using a transvaginal approach. A Martius flap interposition is important to augment success of the repair. If a transvaginal approach fails a transabdominal approach or conversion to cutaneous diversion may be necessary.

RESUMO

ABSTRACT Purpose The present study aimed to determine whether sarcopenia after radical cystectomy (RC) could predict overall survival (OS) in patients with urothelial bladder cancer (UBC). Materials and Methods The lumbar skeletal muscle index (SMI) of 80 patients was measured before and 1 year after RC. The prognostic significance of sarcopenia and SMI decrease after RC were evaluated using Kaplan-Meier analysis and a multivariable Cox regression model. Results Of 80 patients, 26 (32.5%) experienced sarcopenia before RC, whereas 40 (50.0%) experienced sarcopenia after RC. The median SMI change was -2.2 cm2/m2. Patients with sarcopenia after RC had a higher pathological T stage and tumor grade than patients without sarcopenia. Furthermore, the overall mortality rate was significantly higher in patients with sarcopenia than in those without sarcopenia 1 year after RC. The median follow-up time was 46.2 months, during which 22 patients died. Kaplan-Meier estimates showed a significant difference in OS rates based on sarcopenia (P=0.012) and SMI decrease (P=0.025). Multivariable Cox regression analysis showed that SMI decrease (≥2.2 cm2/m2) was an independent predictor of OS (hazard ratio: 2.68, confidence interval: 1.007-7.719, P = 0.048). Conclusions The decrease in SMI after surgery might be a negative prognostic factor for OS in patients who underwent RC to treat UBC.

RESUMO

PURPOSE: The present study aimed to determine whether sarcopenia after radical cystectomy (RC) could predict overall survival (OS) in patients with urothelial bladder cancer (UBC). MATERIALS AND METHODS: The lumbar skeletal muscle index (SMI) of 80 patients was measured before and 1 year after RC. The prognostic signifi cance of sarcopenia and SMI decrease after RC were evaluated using Kaplan-Meier analysis and a multivariable Cox regression model. RESULTS: Of 80 patients, 26 (32.5%) experienced sarcopenia before RC, whereas 40 (50.0%) experienced sarcopenia after RC. The median SMI change was -2.2 cm2/m2. Patients with sarcopenia after RC had a higher pathological T stage and tumor grade than patients without sarcopenia. Furthermore, the overall mortality rate was signifi - cantly higher in patients with sarcopenia than in those without sarcopenia 1 year after RC. The median follow-up time was 46.2 months, during which 22 patients died. Kaplan-Meier estimates showed a signifi cant difference in OS rates based on sarcopenia (P=0.012) and SMI decrease (P=0.025). Multivariable Cox regression analysis showed that SMI decrease (≥2.2 cm2/m2) was an independent predictor of OS (hazard ratio: 2.68, confi dence interval: 1.007-7.719, P = 0.048). CONCLUSIONS: The decrease in SMI after surgery might be a negative prognostic factor for OS in patients who underwent RC to treat UBC.

RESUMO

ABSTRACT Standard radical cystectomy (RC) in women involves removal of the distal ureters, bladder, proximal urethra, uterus, ovaries, and adjacent vagina. Furthermore, pelvic organ-preserving RC to treat selected women has become an accepted technique and may confer better postoperative sexual and urinary functions than standard RC, avoiding complications such as incontinence, prolapse, neobladder-vaginal fistula (NVF), and sexual dysfunction, without compromising oncological outcome. This article reports a different surgical approach: a patient who underwent a cutaneous continent reservoir and neovagina construction using a previous ileal orthotopic neobladder after RC. Patient presented no complications and she has no evidence of recurrent disease and is sexually active, with a satisfactory continent reservoir. This case is the first report of this procedure that was able to treat concomitant dyspareunia caused by short vagina and neobladder-vaginal fistula. In conclusion, standard radical cystectomy with no vaginal preservation can have a negative impact on quality of life. In the present case, we successfully treated neobladder fistula and short vagina by transforming a previous ileal orthotopic neobladder into two parts: a continent reservoir and a neovagina. However, to establish the best approach in such patients, more cases with long-term follow-up are needed.

RESUMO

ABSTRACT Introduction: Acute kidney injury (AKI) after major surgeries is associated with significant morbidity and mortality. We aim to report incidence, predictors and associated comorbidities of AKI after radical cystectomy in a large cohort of patients. Materials and Methods: We conducted a retrospective analysis of 1000 patients who underwent open radical cystectomy in a tertiary referral center. Perioperative serum creatinine measurements were used to define AKI according to the RIFLE criteria (as Risk, Injury and Failure). The predictors of AKI after surgery were determined using univariate and multivariate analyses. Results: Out of 988 evaluable patients, AKI developed in 46 (4.7%). According to RIFLE criteria; AKI-Risk, AKI-Injury and AKI-Failure occurred in 26 (2.6%), 9 (0.9%) and 11 (1.1%) patients, respectively. Multivariate analysis showed that performing nephroureterectomy with cystectomy (Odds ratio [OR]: 4.3; 95% Confidence interval [CI]: 1.3-13.6; p=0.01) and the development of high grade complications (OR: 3.8; 95% CI 1.9-7.2; p<0.0001) were independently associated with AKI. Conclusions: AKI is a significant morbidity after radical cystectomy and the term should be included during routine cystectomy morbidity assessment.
