ABSTRACT

OBJETIVO: La ureteroscopia constituye una opción con elevadas tasas de éxito en el tratamiento de los cálculos ureterales, siendo superiores a la litotricia en la mayoría de los casos. El objetivo de nuestro trabajo es analizar las variables clínicas y demográficas, resultados y complicaciones, de nuestra serie de pacientes sometidos a ureteroscopia en régimen de cirugía mayor ambulatoria (CMA) y analizar los factores predictores de éxito del tratamiento y necesidad de ingreso hospitalario. MÉTODOS: Analizamos de forma retrospectiva 402 pacientes sometidos a ureteroscopia semirrígida (URS) por litiasis ureteral en régimen de CMA en nuestro centro entre 2004 y 2012. Excluimos los pacientes con catéter doble jota (CDJ) previo. Clasificamos las litiasis según su localización (lumbar, iliaca, pélvica) tamaño (< o > 1cm) y número (única o múltiple). El tratamiento se realizó mediante extracción con pinzas, LASER Holmium, o fragmentación mecánica. La revisión se realizó mediante radiografía simple de abdomen y ecografía al mes de la intervención. Consideramos éxito del procedimiento los pacientes libres del cálculo tratado o con restos litiásicos ureterales <3 mm al mes de la intervención. Realizamos un análisis univariante y multivariante mediante chi cuadrado y regresión logística para identificar los factores implicados en el éxito y la no necesidad de hospitalización. RESULTADOS: Incluimos 269 pacientes, 59% varones. La mayoría de la litiasis fueron únicas (92,2%), menores de un centímetro (76,6%), de localización pélvica (62,1%) e izquierdas (57,2%). Realizamos dilatación neumática del orificio ureteral en 67,3% de los casos, tratamos la mayoría de las litiasis con LASER (48%) y dejamos CDJ postoperatorio en el 92,2% de los casos. En el 83,3% de los procedimientos no existieron complicaciones intraoperatorias, realizándose el 89,6% en CMA, considerándolo éxito en el 82,2%. En el análisis multivariante, la lateralidad izquierda (p<0,001) y la localización pélvica de la litiasis (p=0,01) resultaron factores predictivos independientes de éxito del procedimiento. Para la necesidad de ingreso hospitalario solo la ausencia de complicaciones intraoperatorias resulto factor predictivo independiente (p=0,006). CONCLUSIONES: La lateralidad izquierda y la localización pélvica constituyen los factores predictores independientes de éxito de la URS. La ausencia de complicaciones intraoperatorias constituye el factor predictor independiente de no precisar hospitalización (AU)


OBJECTIVES: To analyze the outcomes, predictors of success and predictors of need for hospital admission in our series of patients who underwent ureteroscopy (URS) as a major outpatient surgery (MOS) procedure. METHODS: We carried out a retrospective analysis of 402 patients who had undergone semi-rigid URS for ureteral calculi as a MOS procedure in our center between 2004 and 2012. Patients with previous DJ catheter were excluded. We classified the calculi according to their location (lumbar, pelvic, iliac), size (< or > 1cm) and number (single or multiple). Follow-up was done by plain X-ray of the abdomen and ultrasound one month after surgery. The procedure was considered successful when patients were free from the treated calculi or had ureteral fragments <3 mm one month after surgery. Univariate and multivariate analyses were carried out to identify the factors involved in success and hospitalization not being required. RESULTS: A total of 269 patients were included. The majority of the stones were single (92.2%), <1 cm in size (76.6%), pelvic (62.1%), and left-sided (57.2%). 89.6% of the procedures were performed as MOS and 82.2% were considered to be successful. In the multivariate analysis, left-sided (p<0.001) and pelvic location of the calculi (p=0,01) were found to be independent predictors for the success of the procedure In terms of hospital admission, the only independent predictor was the presence of intraoperative complications (p=0.006). CONCLUSIONS: Left-sided and pelvic locations were the independent predictors for the success of the URS. A lack of intraoperative complications was the independent predictor for not requiring hospitalisation (AU)

ABSTRACT

El donante vivo relacionado (DVR) tiene importantes ventajas cuando se compara con el donante cadáver (DC) en términos de mejor supervivencia del paciente y del injerto, así como de un tiempo de espera menor. Desde 1985 hemos realizado en nuestro Centro 176 trasplantes renales (TR), de los cuales 156 (89 por ciento) son de DC y 20 (11 por ciento) de DVR en primer grado. El objetivo de este trabajo es presentar nuestra experiencia de 5 años con el DVR. A todos los donantes se les realizó un estudio protocolizado de función renal, bioquímico, metabólico y angiográfico. Doce niños recibieron su primer trasplante y 8 fueron retrasplantes ( 6 segundos, 1 tercero y 1 cuarto). El tratamiento inmunosupresor consistió en terapia clásica (azatioprina, ciclosporina prednisona) con inducción de suero antitimocítico. El FK506 y el micofenolato mefetil también se han empleado en alguno de ellos. En cuatro injertos fue necesario reaizar cirug´´ia arterial de banco debido a a presencia de anomalías vasculares. La complicación más signifiativa ha sido a pérdida de un injerto debida a una microangiopatía trombótica asociada al FK506. La supervivencia tanto del donante como del receptor es del 100 por ciento y la supervivencia actuarial del injerto a los 5 años es del 95 por ciento, con un infiltrado glomerular medio de 81,33 ml/min/1,73 m2 (AU)

ABSTRACT

Living related donor (LRD) provides significant advantages when compared with cadaveric donor (CAD) in term of improved patient and graft survival and shorten waiting time. From 1985, 176 kidney transplants were performed at our Center. Of these, 156 (89%) were from CAD and 20 (11%) were from LRD, first degree. The purpose of this paper is to show our experience at 5 years with use of LRD. All donors underwent standardized metabolic workup, angiography assessed and renal function test. Twelve children received their first transplant and 8 were retransplant (6-second, 1-third and 1-fourth). Immunosuppressive therapy consisted of globulin antithymocyte, azathioprine, cyclosporine and prednisolone, using FK506 and mycophenolate mofetil in some of them. Four kidneys with multiple renal arteries were reconstructed ex vivo with microsurgical technique before transplantation. The most significant morbidity was due to FK506-associated thrombotic microangiopathy (TMA) with graft lost. All patients (donor and recipient) survived. Five years graft survival rate is 95% and mean glomerular filtration rate is 81.33 ml/min/1.73 m2.

ABSTRACT

OBJECTIVE: To analyze the results of the first two years of application of the clinical pathway for transurethral resection (TUR) of bladder tumors at La Paz University Hospital. METHODS: We developed a clinical pathway of 4 hospital stays (5 days) for TUR of the bladder that included the following: matrix-verification, treatments prescribed, verification of changes, patient information sheet and patient satisfaction questionnaire. The information for the evaluation of the results were obtained from the pathway records and data on the activities of the Urology services. To assess the results for efficiency in the use of resources, the mean duration of hospital stay of patients in the pathway were compared with that of a control group comprised of 50 randomly selected patients submitted to TUR of the bladder in 1997. RESULTS: From June 1998 to May 2000, 481 of the 494 (97.4%) treated patients entered the clinical pathway. CONCLUSIONS: In our experience, the clinical pathway for the urinary bladder is a useful instrument for developing the clinical management of this condition. It reduces the unwanted changes in patient care and hospital stay, carries a low incidence of complications and readmissions, and achieves a high degree of patient satisfaction.
