ABSTRACT

BACKGROUND@#Studies have classified muscle-invasive bladder cancer (MIBC) into primary (initially muscle-invasive, PMIBC) and secondary subtypes (initially non-muscle-invasive but progresses, SMIBC), for which controversial survival outcomes were demonstrated. This study aimed to compare the survival outcomes between PMIBC and SMIBC patients in China.@*METHODS@#Patients diagnosed with PMIBC or SMIBC at West China Hospital from January 2009 to June 2019 were retrospectively included. Kruskal-Wallis and Fisher tests were employed to compare clinicopathological characteristics. Kaplan-Meier curves and Cox competing proportional risk model were used to compare survival outcomes. Propensity score matching (PSM) was employed to reduce the bias and subgroup analysis was used to confirm the outcomes.@*RESULTS@#A total of 405 MIBC patients were enrolled, including 286 PMIBC and 119 SMIBC, with a mean follow-up of 27.54 and 53.30 months, respectively. The SMIBC group had a higher proportion of older patients (17.65% [21/119] vs. 9.09% [26/286]), chronic disease (32.77% [39/119] vs . 22.38% [64/286]), and neoadjuvant chemotherapy (19.33% [23/119] vs . 8.04% [23/286]). Before matching, SMIBC had a lower risk of overall mortality (OM) (hazard ratios [HR] 0.60, 95% confidence interval [CI] 0.41-0.85, P  = 0.005) and cancer-specific mortality (CSM) (HR 0.64, 95% CI 0.44-0.94, P  = 0.022) after the initial diagnosis. However, higher risks of OM (HR 1.47, 95% CI 1.02-2.10, P  = 0.038) and CSM (HR 1.58, 95% CI 1.09-2.29, P  = 0.016) were observed for SMIBC once it became muscle-invasive. After PSM, the baseline characteristics of 146 patients (73 for each group) were well matched, and SMIBC was confirmed to have an increased CSM risk (HR 1.83, 95% CI 1.09-3.06, P  = 0.021) than PMIBC after muscle invasion.@*CONCLUSIONS@#Compared with PMIBC, SMIBC had worse survival outcomes once it became muscle-invasive. Specific attention should be paid to non-muscle-invasive bladder cancer with a high progression risk.

ABSTRACT

Primary endometrioid adenocarcinoma of the rectovaginal septum is rare. Its pathogenesis is not clear and there is no standard treatment. One patient with endometrioid adenocarcinoma of the rectovaginal septum arising from deep infiltrative endometriosis was admitted to Qingdao Municipal Hospital. The patient presented with incessant menstruation and abdominal distension. She had bilateral ovarian endometriotic cystectomy 6 years ago. Imaging findings suggested a pelvic mass which might invade the rectovaginal septum. Pathological results of primary surgery confirmed endometrioid carcinoma of the pelvic mass arising from the rectovaginal septum. Then she had a comprehensive staged surgery. Postoperative chemotherapy was given 6 times. No recurrence or metastasis was found during the 2-year follow-up. The possibility of deep infiltrating endometriosis and its malignant transformation should be considered in the differential diagnosis of a new extragonadal pelvic lesion in a patient with a history of endometriosis, which would avoid misdiagnosis and missed diagnosis.

ABSTRACT

Bladder cancer is a common malignant tumor of the urinary system.The prognosis of patients with positive lymph nodes is worse than that of patients with negative lymph nodes.An accurate assessment of preoperative lymph node statushelps to make treatmentdecisions,such as the extent of pelvic lymphadenectomy and the use of neoadjuvant chemotherapy.Imaging examination and pathological examination are the primary methods used to assess the lymph node status of bladder cancer patients before surgery.However,these methods have low sensitivity and may lead to inaccuate staging of patients.We reviewed the research progress and made an outlook on the application of clinical diagnosis,imaging techniques,radiomics,and genomics in the preoperative evaluation of lymph node metastasis in bladder cancer patients at different stages.

ABSTRACT

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.

ABSTRACT

ABSTRACT Purpose: Contrast-enhanced CT scan is the standard staging modality for patients with bladder cancer undergoing radical cystectomy (RC). Involvement of lymph nodes (LN) determines prognosis of patients with bladder cancer. The detection of LN metastasis by CT scan is still insufficient. Therefore, we investigated various CT scan characteristics to predict lymph node ratio (LNR) and its impact on survival. Also, pre-operative CT scan characteristics might hold potential to risk stratify cN+ patients. Materials and Methods: We analyzed preoperative CT scans of patients undergoing RC in a tertiary high volume center. Retrospectively, local tumor stage and LN characteristics such as size, morphology (MLN) and number of loco-regional LN (NLN) were investigated and correlation to LNR and survival was analyzed. CT scan characteristics were used to develop a risk stratification using Kaplan-Maier and multivariate analysis. Results: 764 cN0 and 166 cN+ patients with complete follow-up and imaging data were included in the study. Accuracy to detect LN metastasis and locally advanced tumor stage in CT scan was 72% and 62%. LN larger than 15mm in diameter were significantly associated with higher LNR (p=0.002). Increased NLN correlated with decreased CSS and OS (p=0.001: p=0.002). Furthermore, CT scan based scoring system precisely differentiates low-risk and high-risk profiles to predict oncological outcome (p <0.001). Conclusion: In our study, solely LN size >15mm significantly correlated with higher LNR. Identification of increased loco-regional LN was associated with worse survival. For the first time, precise risk stratification based on computed-tomography findings was developed to predict oncological outcome for clinical lymph node-positive patients undergoing RC.

ABSTRACT

ABSTRACT Introduction: One of the most remarkable characteristics of urothelial carcinomas is multifocality. However, occurrence of synchronous bladder cancer and upper urinary tract urothelial cancer (UTUC) is exceptional. Minimally invasive approach for these synchronous tumors was just occasionally reported (1-4). The aim of this video article is to describe step-by-step the technique for simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion (ICUD). Patients and methods: A 66-year-old female presented with synchronous BCG refractory non-muscle invasive bladder cancer and a right-side UTUC. She was a former smoker and had previously been submitted to multiple transurethral resections of bladder tumor, BCG and right distal ureterectomy with ureteral reimplant. We performed a simultaneous laparoscopic right nephroureterectomy and robot-assisted anterior pelvic exenteration with totally intracorporeal ICUD. Combination of robot-assisted and pure laparoscopic approaches was proposed focusing on optimization of total operative time (TOT). Results: Surgery was uneventful. TOT was of 330 minutes. Operative time for nephroureterectomy, anterior pelvic exenteration and ICUD were 48, 135, 87 minutes, respectively. Estimated blood loss was 150mL. Postoperative course was unremarkable and patient was discharged after 7 days. Histopathological evaluation showed a pT1 high grade urothelial carcinoma plus carcinoma in situ both in proximal right ureter and bladder, with negative margins. Twelve lymph nodes were excised, all of them negative. Conclusion: In our preliminary experience, totally minimally invasive simultaneous nephroureterectomy and cystectomy with intracorporeal ICUD is feasible. Pure laparoscopic approach to upper urinary tract may be a useful tactic to reduce total operative time.

ABSTRACT

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.

ABSTRACT

ABSTRACT Background: Guideline-based best practice treatment for muscle invasive bladder cancer (MIBC) involves neoadjuvant chemotherapy followed by radical cystectomy (NACRC). Prior studies have shown that a minority of patients receive NACRC and older age and renal function are drivers of non-receipt of NACRC. This study investigates treatment rates and factors associated with not receiving NACRC in MIBC patients with lower comorbidity status most likely to be candidates for NACRC. Materials and Methods: Retrospective United States National Cancer Database analysis from 2006 to 2015 of MIBC patients with Charlson comorbidity index (CCI) of zero. Analysis of NACRC treatment trends in higher CCI patients was also performed. Results: 15.561 MIBC patients met inclusion criteria. 1.507 (9.7%) received NACRC within 9 months of diagnosis. NACRC increased over time (15.0% in 2015 compared to 3.6% in 2006). Higher NACRC was noted in females, cT3 or cT4 cancer, later year of diagnosis, and academic facility treatment. Lower utilization was noted for blacks and NACRC decreased with increasing age and CCI. Only 16.9% of patients aged 23-62 in the lowest age quartile with muscle invasive bladder cancer and CCI of 0 received NACRC. Conclusions: Although utilization is increasing, receipt of NACRC remains low even in populations most likely to be candidates. Further study should continue to elucidate barriers to utilization of NACRC.

ABSTRACT

ABSTRACT Introduction: The aim of the present prospective-randomized study was to compare perioperative outcomes and complications of bipolar and monopolar TURBT for lateral wall-located non-muscle invasive bladder cancers (NMIBC) under obturator nerve block (ONB). Patients and Methods: 80 patients who underwent TURBT for lateral wall-located primary bladder tumors under ONB from March, 2016 to November, 2019 were included in the present study. The patients were randomized equally into two groups; monopolar TUR (M-TURBT) and bipolar TUR (B-TURBT). The primary and secondary outcomes were safety (obturator jerk and bladder perforation) and efficacy (complete tumor resection and sampling of the deep muscle tissue). Results: Obturator jerk was detected in 2 patients (5%) in M-TURBT while obturator jerk was not observed during B-TURBT (p=0.494). Bladder perforation was not observed in both groups. All of the patients underwent complete tumor resection. There was no significant difference in muscle tissue sampling (67.5% vs. 72.5%, p=0.626) and thermal tissue damage rates (12.5% vs. 25%, p=0.201). The majority of complications were low-grade and the differences in Clavien grade 1-3 complications between groups were not statistically significant. Conclusion: In the treatment of lateral-wall located NMIBCs, either M-TURBT or B-TURBT can be safely and effectively performed by combining spinal anesthesia with ONB. Even so, it should be taken into consideration that low-grade postoperative hemorrhagic complications may occur in patients who undergo M-TURBT.

ABSTRACT

RESUMEN Antecedentes: los avances en cuidados perioperatorios e inmunosupresión permitieron que la su pervivencia de los pacientes trasplantados aumente significativamente, así observamos que la litiasis vesicular es más frecuente en este grupo de pacientes. Objetivo: el objetivo de este trabajo es analizar y describir los resultados obtenidos en colecistecto mías en pacientes trasplantados cardíacos. Material y métodos: seleccionamos los pacientes mediante una búsqueda cruzada entre las bases de datos de Trasplante Cardíaco y Cirugía Biliar. Recopilamos información sobre sus antecedentes médi cos, parámetros clínicos y de laboratorio, entre otros. Resultados: entre enero 1994-diciembre 2017 se realizaron 154 trasplantes cardíacos con una edad media de 40 años; 16 pacientes fueron incluidos en este estudio y en los cuales fue realizada la cole cistectomía laparoscópica posterior al trasplante. No se registraron morbilidad, readmisiones ni mor talidad. Conclusión: la colecistectomía laparoscópica es segura y es el método de elección en pacientes tras plantados cardíacos. Se debe realizar colangiografía intraoperatoria, ya que los predictores de litiasis coledociana suelen estar alterados.


ABSTRACT Background: The advances in perioperative care and immunosuppressive treatment resulted in a significant increase in survival of transplant patients; as a result, cholelithiasis is more common in transplant patients. Objective: The aim of this study is to analyze and describe the results obtained in cholecystectomies in heart transplant patients. Material and methods: We selected patients by cross-referencing the databases of heart transplantation and scheduled biliary surgeries, and collected information on their medical history, clinical parameters and laboratory tests, among other data. Results: Between January 1994 and December 2017, 154 heart transplant procedures were performed; mean age was 40 years; 16 underwent laparoscopic cholecystectomy after heart transplantation and were included in this study. There were no complications, readmissions or deaths. Conclusion: Laparoscopic cholecystectomy is safe and is the method of choice for heart transplant patients with cholelithiasis. Intraoperative cholangiography should be performed as the predictors of choledocholithiasis are usually abnormal.

ABSTRACT

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.

ABSTRACT

ABSTRACT Hypothesis: Endoclip can be used as fiducial marker in urology. Objective: To assess the feasibility, cost effectiveness and reliability of endoclips as novel fiducial markers in precision radiotherapy, as part of a trimodality bladder-preserving treatment (TBPT) of muscle-invasive bladder carcinoma. Materials and Methods: This retrospective study was performed at Weifang People's Hospital (Weifang, China) from January 2015 to June 2018. A total of 15 patients underwent TBPT. Endoclips were applied to healthy edges of the resected bladder wall as novel fiducial markers. Radio-sensitizing chemotherapy and routine precision radiotherapy were given. The number and position of the endoclips during radiotherapy sessions were monitored. Complications and tumor recurrence were analyzed. Results: The mean age (±standard deviation) of the patients was 67±10 years (range 46-79). There were 3 females and 12 males. Forty-nine endoclips were applied in all patients (3.3±0.8). The tumor was completely visibly resected in all patients. The number of endoclips remained the same through the planned last radiotherapy session (3.3±0.8), i.e., none were lost. All endoclips were removed after the last radiotherapy session. The average number of follow-up months was 38.9±13.2 (range 11-52). There were no procedure-related complications at discharge or follow-up. At one-year, overall recurrence-free survival was 93.3%. Two patients had recurrences at 18 months and 10 months after TBPT, respectively, and salvage radical cystectomy was performed with no further recurrences. Another patient died due to metastasis 9 months after the completion of therapy. Conclusions: Endoclips are reliable, safe and cost-effective as novel fiducial markers in precision-radiotherapy post-TBPT.

ABSTRACT

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.

ABSTRACT

Primary signet-ring cell carcinoma of the urinary bladder is a rare tumor. The overall incidence is approximately 0.12-0.6% of all urinary bladder malignancies. The majority of the patients present in an advanced stage with a uniformly grim prognosis. As signet-ring cell carcinomas are more common in the gastrointestinal tract, a possibility of metastasis needs to be considered. Here we report, a 42-year-old patient who presented with hematuria and was diagnosed with a urinary bladder tumor. The patient was managed with partial cystectomy and pelvic lymph node dissection. The histopathological examination confirmed primary signet-ring cell carcinoma of the urinary bladder.

ABSTRACT

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.

ABSTRACT

ABSTRACT Purpose: To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit. Materials and methods: Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, deterioration of the upper tract, intraoperative blood loss and patient-reported quality of life (HRQOL). The modified Wallace 1 technique involved eversion of the ureteral plate and bowel mucosa edges, which were anastomosed together in running fashion, while the outher anastomotic wall was augmented with sero-serosal interrupted sutures. Results: The mean (SD) follow-up time was 26.1 (5.7) months in group I and 25.2 (4.8) months in group II, during which, anastomotic stricture was observed in 8 patients (12%) from the first and 2 patients (3%) from the second group (p < 0.05). The anastomotic leakage rate was significantly higher in first group (17% vs. 8.5%, p< 0.05), while patient-reported HRQOL outcomes were similar between groups after the 12 month follow-up period. Conclusions: By using a modified Wallace technique, we were able to significantly lower anastomotic stricture and anastomotic leakage rates, which are major issues in minimizing both short- and long-term postoperative complications.
