RESUMO

BACKGROUND: Living donor kidney transplantation (LDKT) is one of the best options for patients with chronic renal failure, but approximately one-third of cases are limited by incompatibility ABO and/or HLA between recipient and donor. This study aims to analyze the surgical complications and bleeding events presented in ABO-incompatible (ABOi) and HLA-incompatible (HLAi) patients within a pre-transplant desensitization program compared with ABO-compatible (ABOc) recipients. MATERIAL AND METHODS: We performed a retrospective analysis of ABOi and HLAi recipients undergoing LKDT between 2009 and 2019, resulting in a total of 62 patients that we compared with the same number of ABOc performed consecutively before 2019. The following variables were analyzed: surgical complications, presence, size and rate of reintervention of peri-graft hematomas, and number of transfusions received in the postoperative period. RESULTS: No statistical differences were shown in donor and recipient age, BMI, or sex; in the case of pre-surgical hematocrit, the ABOi group presented slightly lower figures. In the incompatible group (ABOi + HLAi), we found a greater number of postoperative surgical complications when analyzing the number of hematomas, size, need for surgical reintervention, and the number of blood units transfused; incompatible patients showed higher rates of hematomas, need for surgical reinterventions, and transfused units (P < .05). CONCLUSION: Desensitized patients need more transfusions, have a greater number and size of hematomas, and have higher reintervention rates. Although these are present in greater numbers, we did not observe statistically significant differences in the number of surgical complications.

RESUMO

OBJECTIVE: Kidney transplantation process involves a series of challenges such as the shortage of organs worldwide for a population waiting for a first and subsequent kidney transplants and the search forthe most appropriate graft for each recipient, optimizing the ischemia time as much as possible, minimizing the impact of surgery and subsequent immunosuppressive therapy. METHODS: We carry out a review of the different advances and lines of research in the different areas involved in the kidney transplantation process from strategies focused on increasing the donor pool, enabling the expansion of living donor programs as well as orga preservation strategies previous to transplantation surgery.The arrival of robotic surgery in the field of kidney transplantation has been an important milestone in the last decade, showing improvements compared to traditional open surgery, maintaining satisfactory functional results, although its implementation is currently reduced with technical limitations in the extension to any type of recipient. New immunosuppressive agents that minimize potential side effects or reduce anticalcineurinic drugsdoses are also important lines of research. CONCLUSIONS: The future of kidney transplantation involves the search for increasingly global strategies to improve the supply of organs, improvements in the conditioning and preservation of grafts or the global development of minimally invasive surgery in the different areas of kidney transplantation. The weight of biotechnology and gene therapies represent promising tools in the field of tissue generation or targeted immunosuppressive therapies.

RESUMO

OBJECTIVE: We report the case of a young patient without known cardiovascular risk factors, complaining of lumbar colic pain due to renal infarction. METHODS: Differential diagnosis of lumbar colic pain must include some rare events. We performed a review of the current knowledge on the topic. RESULTS/CONCLUSION: The increasing difficulty in the diagnosis of these pathology lies on its clinical suspect, which can be clear when having cardiovascular risk factors. Its diagnosis, on a rare scenario, needs leucocytosis and LDH rising as suspicious indicators. Computed tomography, MRI, radionuclids and arteriography may confirm diagnosis. Treatment is based on thrombolytic therapy, anticoagulants and ontiagregants.

RESUMO

Objetivo: Presentamos un caso clínico de dolor cólico hacia fosa lumbar ocasionado por infarto renal en un paciente joven sin antecedentes de riesgo tromboembólicos conocidos. Métodos: Existen procesos poco habituales que se deben incluir en el diagnóstico diferencial del dolor cólico lumbar. Realizamos una revisión en el conocimiento actual. Resultado/Conclusiones: La mayor dificultad para el diagnóstico de esta patología radica en su sospecha clínica, que es clara si existen factores de riesgo cardiovascular. La aparición en un escenario no habitual, hace necesario recurrir a indicadores complementarios como la leucocitosis y la elevación de la LDH. Su confirmación se realiza mediante tomografía computada, RMN, gammagrafía o arteriografía. Su tratamiento necesita medidas trombolíticas, anticoagulantes y/o antiagregantes (AU)

RESUMO

OBJECTIVES: To determine the percentage of renal cell carcinomas incidentally diagnosed (IRCC) and to compare their clinical and pathological characteristics with symptomatic or non-incidentally diagnosed tumors (SRCC). METHODS: We retrospectively study 189 patients who were diagnosed of renal carcinoma between 1990 and 1999. 166 underwent surgery (149 radical nephrectomy; 17 nephron-sparing surgery). We determine the percentage of IRCC detected by radiological tests and compare them with the SRCC diagnosed after presenting with some of the classic symptoms or metastasis, with special focus on tumor size, pathology stage, tumor recurrence, progression and evolution. RESULTS: 87 SRCC (46%); 102 SRCC (54%). There are not differences in terms of age, gender, side, and postoperative hospital stay. Tumor size was higher in the SRCC (mean 8.5 cm) than in the IRCC (6.3 cm). SRCC tumor stage was: pT1 27.3%, pT2 27.3%, pT3a 23.8%, pT3b 16.6%, pT3c 2.3%, and pT4 2.3%; IRCC stage was: pT1 51.3%, pT2 25.6%, pT3a 10.9%, pT3b 10.9%, pT3c 1.2%, and no pT4. The percentage of patients with lymph node involvement was higher (p = 0.02) in the SRCC (15%) than in the IRCC (4.8%). The percentage of patients with metastasis at the time of diagnosis was higher in the SRCC group (26%) than in the IRCC (9.2%). Recurrences were more frequent in the SRCC Group (8.3%) than in the IRCC (1.2%) (p = 0.07). Tumor progression was more frequent in the SRCC group (34%) than in the IRCC (7.3%) (p<0.01). 76% of the patients undergoing nephron sparing surgery were IRCC. CONCLUSIONS: Currently, there is a high percentage of IRCC (46% in our series from 1990-99). Renal tumors presenting as IRCC have better prognosis, since they have significantly smaller size, lower stage, less advanced disease, less recurrences, and less progression than SRCC.

El tamaño fue mayor enlos ARS (media 8.5 cm.) que en los ARI (media 6.3cm.). El estadio tumoral en los ARS: pT1 27.3%, pT227.3%, pT3a 23.8%, pT3b 16.6%, pT3c 2.3%, pT42.3%; mientras que en los ARI: pT1 51.3%, pT225.6%, pT3a 10.9%, pT3b 10.9%, pT3c 1.2% y ningunopT4. La proporción de pacientes con enfermedadganglionar fue mayor (p=0,02) en los ARS (15%) queen los ARI (4.8%). La proporción de pacientes conmetástasis a distancia en el momento del diagnósticofue mayor (p<0,01) en los ARS (26%) que en los ARI(9.2%). Las recidivas fueron más frecuentes (p=0,07) enlos ARS (8.3%) que en los ARI (1.2%). La progresión fuemás frecuente (p<0,01) en los ARS (34%) que en losARI (7.3%). De los pacientes que recibieron cirugía conservadora,el 76% fueron ARI.CONCLUSIONES: En la actualidad existe un elevadoporcentaje de ARI (46% en nuestra serie de los años1990-99). Los tumores renales que debutan como ARItienen mejor pronóstico, ya que presentan significativamentemenor tamaño, mejor estadio, enfermedadmenos avanzada, menos recidivas y menor progresiónque los ARS

RESUMO

OBJECTIVES: To analyse the role of CT-scan on preoperative determination of bladder and lymph node involvement of infiltrative bladder cancer, and its possible impact on the surgical management of these patients. METHODS: Retrospective study including 115 patients with the diagnosis of infiltrative bladder cancer between 1984 and 1999. The ability of CT-scan for bladder and lymph node staging was evaluated comparing results with the findings after radical surgery. Potential impact of this imaging technique on change of surgical attitudes was evaluated. RESULTS: Perivesical involvement estimation by CT-scan was right in 36.5%, underestimated in 49.6% and overestimated in 14%. The more advanced the perivesical involvement the lower the sensitivity for CT-scan in perivesical staging. The more locally advanced tumour the higher specificity, oscillating between 44% for pT2 and 94% for pT4. In reference to lymph node staging, it was correct in 71.3% of the cases, although this percentage depended almost exclusively on patients with negative nodes (N-). However, there was a 24.3% understaging rate which corresponded to the majority of N+ patients. These data offer a 28% sensitivity, 93% specificity, 68% positive predictive value, and 72% negative predictive value. Finally, the reliability of bladder staging in patients with lymph node involvement (N+) (39 patients) was established; it was correctly estimated in as low as 30% of the cases with a 70% understaging rate. CT-scan would have modified surgical attitudes in only 6 patients (5%), all of them with advanced tumours. CONCLUSIONS: The impact of CT-scan on infiltrative bladder cancer clinical staging is relatively low. The highest benefit is obtained in patients suspect of having advanced disease. Limitation to this group would result in significative cost reductions with low risk for unappropriate surgical management.

RESUMO

OBJETIVOS: Analizar el papel de la T.A.C. en la determinación prequirúrgica de afectación vesical y ganglionar, del cáncer vesical infiltrante, así como su posible impacto en el manejo quirúrgico de estos pacientes. MÉTODOS: Se realizó un estudio retrospectivo en 115 pacientes con cáncer vesical infiltrante diagnosticados en el período 1984-1999. Se determinó la capacidad de la T.A.C. para el estadiaje vesical y ganglionar y se compararon los resultados con los obtenidos tras la cirugía radical. Se evaluó el posible impacto de esta técnica de imagen en el cambio de actitud quirúrgica en estos pacientes. RESULTADOS: La estimación de afectación perivesical con T.A.C. fue correcta en 36,5 per cent, fue subestadiada en 49,6 per cent, y sobreestadiada en 14 per cent. La T.A.C. para el estadiaje perivesical posee una sensibilidad más baja cuanto más avanzada es dicha afectación. Su especificidad es más elevada cuanto más avanzado localmente sea el tumor, oscilando entre 44 per cent en los pT2 y el 94 per cent en los pT4.En lo referente al estadiaje ganglionar, es correcto en 71,3 per cent de los casos, aunque este porcentaje depende casi exclusivamente de los pacientes con ganglios negativos (N-). Existe, sin embargo, una tasa de subestadiaje de 24,3 per cent que corresponde a la mayoría de los pacientes N+. Estos datos nos ofrecen una sensibilidad del 28 per cent, especificidad de 93 per cent, valor predictivo positivo de 68 per cent, y predictivo negativo de 72 per cent.Por último, se establece la fiabilidad del estadiaje vesical en los pacientes con afectación ganglionar (N+) (39 pacientes), habiendo estimado correctamente un escaso 30 per cent con una tasa de subestadiaje del 70 per cent. Esta prueba solo habría modificado la actitud quirúrgica en 6 pacientes (5 per cent), todos en estadios avanzados. CONCLUSIONES: El impacto de la T.A.C. en el estadiaje clínico del cáncer vesical infiltrante es relativamente bajo. El mayor beneficio se obtiene en pacientes con sospecha de enfermedad avanzada. Su limitación a este grupo supondría una significativa reducción de costes con bajo riesgo de un manejo quirúrgico inapropiado (AU)

RESUMO

OBJECTIVE: To report a case of choriocarcinoma of the bladder during the different periods of its evolution. The anatomopathological study showing dedifferentiation of a transitional cell tumor is presented and the histogenesis of this rare tumor is discussed. METHODS: A case of a rapidly progressing transitional cell tumor of the bladder that dedifferentiated into choriocarcinoma is presented. The pathological findings of the first resections of the transitional cell tumor that progressed to choriocarcinoma are presented and the histogenesis is discussed. RESULTS/CONCLUSIONS: Choriocarcinoma of the bladder is very rare, highly malignant and carries a poor prognosis. Its origin is widely accepted to be in the dedifferentiation of a transitional cell tumor. The use of immunohistochemistry and the positivity of HCG support the diagnosis.

RESUMO

Objetivos: Presentar un caso clínico de coriocarcinoma vesical en distintos momentos de su evolución con estudio anatomo patológico amplio en donde parece demostrarse la postura de la desdiferenciación de un tumor de células transicionales.Destacar por su extraordinaria infrecuencia y rareza al coriocarcinoma vesical, el cual plantea la duda y la discusión sobre su histogénesis debatida por varios autores.Métodos Y Resultados: Se presenta un caso clínico de un tumor vesical de células transicionales que evoluciona progresiva y rápidamente, desdiferenciándose en un coriocarcinoma. Se presenta el estudio anatomo patológico de las primeras resecciones del tumor de células transicionales y su evolución hacia coriocarcinoma. Se presenta la discusión sobre la histogénesis.Conclusiones: El coriocarcinoma vesical es extremadamente raro e infrecuente, con alto grado de malignidad y mal pronóstico. Su origen mas ampliamente aceptado se encuentra en la desdiferenciación de un tumor de células transicionales. El empleo de la inmunohistoquímica y la positividad para HCG apoya el diagnostico (AU)
