Predictors of success and hospitalization in semi-rigid ureteroscopy for lithiasis as an outpatient procedure.

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.

Renocolic fistula as a complication of radiofrequency in the treatment of renal cell carcinoma.

METHOD: Beyond postoperative suspicion, retrograde pyelogram was performed, the images of which are displayed, and demonstrated the fistula. RESULTS: Treatment has been definitive nephrectomy after failed attempt to seal the fistula with suture and TachoSil. CONCLUSIONS: Although radiofrequency ablation can be a valid technique for treating small renal tumors in patients with high morbidity, it is not without significant complications as described in this case, despite the precautions taken.

Fístula renocólica como complicación de radiofrecuencia para tratamiento de carcinoma renal de células claras / Renocólic fistula as a complication of ratiofrequency in the treatment of renal cell carcinoma

OBJETIVO: Describir un caso clínico de fístula reno cólica como complicación de ablación por radiofrecuencia de carcinoma de células renales. Se revisa la literatura y se exponen las diferentes actitudes diagnósticas y terapéuticas. MÉTODO: Tras la sospecha postoperatoria se realizó pielografía retrograda, cuyas imágenes se muestran, que demuestra la fístula. RESULTADO: El tratamiento definitivo ha sido la nefrectomía tras intento fallido de sellar la fístula con sutura y tachosil. CONCLUSIÓNES: Si bien la ablación por radiofrecuencia puede ser una técnica válida para el tratamiento del tumores renales de pequeño tamaño en pacientes con elevada morbilidad, no está exenta de complicaciones importantes como la descrita en este caso, a pesar de las precauciones tomadas(AU)

Vía clínica para la RTU de neoformaciones vesicales. Análisis de los 2 primeros años de implantación / Clinical pathway for TUR of bladder tumors: analysis of the first two years of application

OBJETIVOS: Analizar los resultados obtenidos en los 2 primeros años de implantación de una vía clínica para la resección transuretral (RTU) de neoformaciones vesicales diseñada en el Hospital Universitario La Paz. MÉTODOS: Hemos diseñado para la resección transuretral de vejiga una vía clínica de 4 estancias hospitalarias (5 días), y que incluye la siguiente documentación: matriz-verificación, órdenes de tratamiento, verificación de variaciones, hoja de información iconográfica para el paciente y la encuesta de satisfacción del paciente. La información para la evaluación de resultados se ha obtenido de la documentación de la vía y de los datos de actividad del Servicio de Urología. Para valorar los resultados en la eficiencia en el consumo de recursos, se ha realizado una comparación entre la estancia media de los pacientes en vía clínica y un grupo control compuesto por una muestra aleatoria de 50 pacientes sometidos a RTU vesical durante 1997 (AU)
