Impact of a One-Stop Hematuria Clinic on Overall Survival and Bladder Tumor Recurrence.

BACKGROUND AND OBJECTIVE: One-stop clinics have emerged as a tool to optimize the therapeutic management of cancer patients. The main purpose of this study was to assess the role of the one-stop hematuria clinic (OSHC), as compared to a conventional clinic (CC), on the overall and disease-free survival of patients with bladder cancer. METHODS: A five-year follow-up retrospective and single-center study was conducted in patients with primary bladder tumor diagnosed between 2006 and 2015. The primary outcomes were five-year overall survival and one-year relapse rate. RESULTS: A total of 394 patients (160 in OSHC and 234 in CC) were included. No differences were observed in terms of age, sex, smoking habit or risk group between the OSHC and CC groups. The average times from first symptom to diagnosis (24.9 ± 29.1 vs. 100.7 ± 93.6 days) and from first symptom to treatment (70.2 ± 34.0 vs. 155.0 ± 102.9 days) were significantly lower in the OSHC group than in the CC group (p < 0.001 each). There was no significant difference in the five-year survival rate between OSHC and CC (103/160 vs. 150/234, respectively; p = 0.951), although the proportion of relapses during the first year was significantly lower in the OSHC group (35/139, 25.2%) than in the CC one (74/195, 38.0%; p = 0.02). CONCLUSIONS: OSHC significantly reduced the diagnosis and treatment times. The early-relapse rate was significantly lower in the OSHC group, although the five-year survival rate was similar.

[Usefulness of contrast enhanced ultrasound for evaluation of cystic renal masses.] / Utilidad de la ecografía con contraste en el estudio de las lesiones renales quísticas.

OBJECTIVE: Contrast enhanced ultrasound(CE) consists of the intravenous injection of gasmicrobubbles and their detection within the kidney in differentphases. CE is more accurate than contrast enhancedtomography for detection of septa and wall thicknessvascularization in cystic renal lesions. The purposes ofthis study are to confirm the usefulness of this tool in thecharacterization of complex cystic renal masses and toassess its histological correlation. MATERIALS AND METHODS: Retrospective observationalstudy of 78 patients with complex or indeterminatecystic renal masses who underwent a CE betweenJanuary 2015 - January 2020. RESULTS: Lesions with high suspicion of malignancy(Bosniak III and IV) were identified in 35 patients(45%). A surgical approach was taken in 23 (30%): 18patients with histology of renal cell carcinoma, and onlyin 4 the histology was benign. CE involved a change intherapeutic management due to better definition of thelesion in 48 patients (61.5%). CE has a sensitivity 100%,specificity 91.5%, PPV 81.8%, NPV 100%, and CE hadan important confidence level showed by the area underthe ROC curve (AUC = 0.968). CONCLUSIONS: CE is a useful tool in the characterizationof complex cystic renal lesions. It allows abetter definition of the Bosniak classification for thoseindeterminate or doubtful cases on CT that couldgenerate a change in the therapeutic attitude in manycases. It has a good image - histology relation.

Metástasis de carcinoma de mama en uréter. Presentación de un caso clínico / Metastasis of breast carcinoma in the ureter. Presentation of a clinical case

OBJETIVO: Resaltar la importancia del seguimiento estrecho a largo plazo de pacientes con antecedente de carcinoma de mama. MATERIALES Y MÉTODOS: Presentación de un caso clínico. RESULTADOS: Se presenta el caso de una mujer de 55 años de edad con antecedente de carcinoma lobulillar de mama. Recibió tratamiento neoadyuvante, cirugía y quimioterapia y radioterapia posterior. En estudio de imagen de control se diagnosticó de metástasis óseas múltiples. La paciente consultó por dolor lumbar izquierdo de varios meses de evolución, en estudio de imagen se observó hidronefrosis izquierda secundaria a lesión de partes blandas en unión pieloureteral con alteración funcional renal. En biopsia realizada mediante abordaje endoscópico (ureteroscopia) se diagnosticó de metástasis de carcinoma de mama en uréter. CONCLUSIÓN: Las lesiones metastásicas en uréter son extremadamente infrecuentes siendo aún menos frecuentes las de origen mamario con alrededor de diez casos publicados mundialmente. Con el diagnóstico previo de carcinoma de mama, el probable compromiso ureteral debe ser tomado en cuenta especialmente en pacientes con síntomas clínicos y radiológicos de obstrucción de la vía urinaria. Un diagnóstico oportuno es posible que influya en el pronóstico y supervivencia posterior

OBJECTIVE: To assess the importance of long-term close follow-up in patients with breast carcinoma. MATERIALS AND METHODS: To present a case report RESULTS: A case of a 55-year-old woman with history of lobular carcinoma of the breast is presented. She received neoadjuvant treatment, surgery and complementary chemotherapy and radiotherapy. In radiologic imaging studies, multiple bone metastases were diagnosed. The patient consulted for left lumbar pain. Radiologic studies revealed left hydronephrosis secondary to soft tissue lesion in pyeloureteral junction with renal functional impairment. A biopsy performed using an endoscopic approach (ureteroscopy), diagnosed a metastasis of breast carcinoma in the ureter. CONCLUSION: Metastatic lesions in the ureter are extremely rare, even less frequent the ones with breast origin with around ten cases published worldwide. With the previous diagnosis of breast carcinoma, the probable ureteral compromise should be considered especially in patients with clinical and radiological symptoms of urinary tract obstruction. A well-timed and proper diagnosis may influence in prognosis and survival

Metástasis de carcinoma de células renales en localizaciones poco frecuentes: hipófisis, tiroides y mama. Revisión de nuestra experiencia y presentación de tres casos clínicos / No disponible

Objetivo: El Carcinoma de Células Renales (CCR) metastásico puede presentarse en localizaciones anatómicas muy variables y tras varios años de seguimiento. En éste artículo resaltamos la importancia del seguimiento de pacientes con antecedente de CCR. Material y métodos: A partir de la revisión de 76 casos de CCR metastásico que recibieron tratamiento sistémico, se presentan tres casos clínicos con afectación de glándulas hipófisis, tiroides y mama. Discusión: Existe debate acerca del tiempo de seguimiento tras una cirugía por CCR y los métodos de imagen de control por la posibilidad de aparición de metástasis tardías y en lugares atípicos. Conclusión: Es importante mantener la sospecha de enfermedad renal metastásica en pacientes con antecedente de CCR, incluso en aquellos con buena evolución y sin tener en cuenta el tiempo transcurrido desde el diagnóstico inicial

Objective: Metastatic Renal Cell Carcinoma (RCC) may develop in different anatomical locations and after a strict follow up within normal limits. We assess the importance of close follow up in patients with history of RCC through 3 clinical cases with unusual locations of metastatic RCC. Methods: We present 3 cases of metastatic involvement of pituitary, thyroid and mammary glands. We retrospectively review our data base on metastatic RCC with 76 patients. DIscussion: There is not agreement about the time of follow up and image methods requested after surgery of RCC. The reason is the development of late onset and atypical placement metastases. Conclusion: Metastatic disease of renal neoplasms can occur at any time and at any location. It is important to keep suspicion of metastatic renal disease in patients in this background, even in those with good progress and regardless of the years that have passed since the initial diagnosis

Reimplante ureteral laparoscópico / Laparoscopic ureteral reimplantation

Aunque el reimplante ureteral laparoscópico (RUL) tiene una trayectoria de más de 20 años, su presencia en la literatura es relativamente escasa, casi siempre en forma de pequeñas series de casos con poca potencia estadística, lo que ha impedido obtener resultados consistentes. Ha demostrado ser una técnica segura y efectiva, mejorando el perfil de seguridad y complicaciones perioperatorias con respecto al reimplante ureteral abierto (RUA). Los escasos resultados a largo plazo sugieren una tasa de éxito similar entre los abordajes abierto y laparoscópico. Aunque no se han encontrado en la literatura evidencias firmes de las ventajas de las técnicas anti-reflujo en adultos, la mayor parte de las series publicadas incluyen estas técnicas. El reimplante ureteral se considera el tratamiento de elección en las lesiones ureterales por debajo del cruce iliaco. Ésta es su principal indicación actualmente. El reconocimiento intraoperatorio de la lesión y el RUL inmediato evitan otras complicaciones, pero la mayoría de las lesiones ureterales se diagnostican en el postoperatorio temprano. Aunque las recomendaciones clásicas aconsejan la derivación urinaria y tratamiento diferido, el abordaje inmediato es factible, y de hecho parece mejorar los resultados en complicaciones, estancia y función renal a largo plazo. En las situaciones postoperatorias de peritonitis secundarias a una fístula ureteral, el RUL inmediato ofrece ventajas específicas, al menos teóricamente, por el efecto protector del neumoperitoneo en las sepsis de origen abdominal

Although the laparoscopic ureteral reimplantation (LUR) has a history of over 20 years, its presence in the literature is relatively sparse, almost always in the form of small case series with low statistical power, which has prevented consistent results. It has proven to be a safe and effective technique, improving the safety profile and perioperative complications compared to open ureteral reimplantation (OUR). The few long-term results suggest a similar success rate between the open and laparoscopic approaches. Although we do not found in the literature a strong evidence of the benefits of anti-reflux reimplantation techniques in adults, most of the published series include these procedures. Ureteral reimplantation is considered the treatment of choice in ureteral injuries below the iliac vessels. This is its main indication now. Intraoperative recognition of the injury and immediate LUR avoid other complications, but most of ureteral injuries are diagnosed in the early postoperative period. Although the classical recommendations advise urinary diversion and delayed treatment, the immediate approach is feasible, and indeed seems to improve results in complications, stay and long-term renal function. In situations of postoperative peritonitis secondary to a ureteral fistula, immediate LUR offers specific advantages, at least theoretically, for the protective effect of pneumoperitoneum in abdominal sepsis

Angiomiolipoma renal en un paciente con esclerosis tuberosa. Presentación de un caso clínico / Renal angiomyolipoma in a patient with tuberous sclerosis. Case report

OBJETIVO: Resaltar la importancia del manejo y seguimiento estrecho de pacientes con esclerosis tuberosa que asocian angiomiolipomas renales. MÉTODOS: Presentación de un caso clínico. RESULTADOS: Se trata de un paciente varón de 55 años de edad diagnosticado de esclerosis tuberosa en la infancia con posterior hallazgo de masas renales bilaterales y de gran tamaño en estudio de imagen, con compromiso importante de la función renal. El paciente no tuvo un seguimiento adecuado ni recibió tratamiento alguno. Al momento se encuentra en estadio terminal de su enfermedad renal. CONCLUSIÓN: Los pacientes que asocian angiomiolipomas renales y esclerosis tuberosa, presentan características particulares con mayor riesgo de complicaciones por lo que requieren un seguimiento estricto y un manejo específico

OBJECTIVE: To assess the importance of management and close follow-up of patients with tuberous sclerosis that associate renal angiomyolipomas. METHODS: To report a case. RESULTS: A 55 years old men with tuberous sclerosis diagnosed in childhood and later finding of bilateral giant renal masses in imaging studies, with significant compromise of renal function. The patient did not have a proper follow up and did not receive any treatment. At the moment he has end stage kidney disease. CONCLUSION: Patients that associate renal angiomyolipoma and tuberous sclerosis, have specific characteristics with a higher risk of complications requiring strict follow-up and specific treatment

Efficacy of different doses of sugammadex after continuous infusion of rocuronium.

AIM: To evaluate the effects of two different doses of sugammadex after maintenance anesthesia with sevofluorane and remifentanil and deep rocuronium-induced neuromuscular blockade (NMB). METHODS: Patients between 20 and 65 years of age, with American Society of Anesthesiologists physical status classification I-II, undergoing gynecological surgery were included in a prospective, comparative and randomized study. NMB was induced with an injection of 0.6 mg/kg of rocuronium followed by continuous infusion of 0.3-0.6 mg/kg per hour to maintain a deep block. Anesthesia was maintained with sevofluorane and remifentanil. Finally, when surgery was finished, a bolus of 2 mg/kg (group A) or 4 mg/kg (group B) of sugammadex was applied when the NMB first response in the train-of-four was reached. The primary clinical endpoint was time to recovery to a train-of-four ratio of 0.9. Other variables recorded were the time until recovery of train-of-four ratio of 0.7, 0.8, hemodynamic variables (arterial blood pressure and heart rate at baseline, starting sugammadex, and minutes 2, 5 and 10) and adverse events were presented after one hour in the post-anesthesia care unit. RESULTS: Thirty-two patients were included in the study: 16 patients in group A and 16 patients in group B. Only 14 patients each group were recorded because arterial pressure values were lost in two patients from each group in minute 10. The two groups were comparable. Median recovery time from starting of sugammadex administration to a train-of-four ratio of 0.9 in group A and B was 129 and 110 s, respectively. The estimated difference in recovery time between groups was 24 s (95%CI: 0 to 45 s, Hodges-Lehmann estimator), entirely within the predefined equivalence interval. Times to recovery to train-of-four ratios of 0.8 (group A: 101 s; group B: 82.5 s) and 0.7 (group A: 90 s; group B: 65 s) from start of sugammadex administration were not equivalent between groups. There was not a significant variation in the arterial pressure and heart rate values between the two groups and none of the patients showed any clinical evidence of residual or recurrent NMB. CONCLUSION: A dose of 2 mg/kg of sugammadex after continuous rocuronium infusion is enough to reverse the NMB when first response in the Train-Of-Four is reached.
