La colocación de catéteres doble J con anestesia local en régimen ambulatorio es un procedimiento seguro y eficiente para el manejo de distintas patologías ureterales / Office stent placement under local anesthesia is a safe and efficient procedure for the management of multiple ureteral disorders

Objetivo: Evaluar los resultados de la colocación de catéteres doble J con anestesia local para el manejo de distintas patologías ureterales. Métodos: Estudio retrospectivo de 45 cateterismos ureterales consecutivos con anestesia local desde enero de 2015 hasta julio de 2016. Se incluyeron pacientes hemodinámicamente estables con una obstrucción o fístula urinaria o para la identificación ureteral durante una cirugía abdominopélvica. Cinco minutos antes del procedimiento se instilaron 10 ml de gel-lidocaína y 50 ml de suero-lidocaína en la vejiga. Se colocaron catéteres 4,8 Fr mediante un cistoscopio flexible de 15,5 Fr y escopia. Se analizaron las características y resultados de los procedimientos. Resultados: Se realizaron 45 procedimientos (33 colocaciones, 12 recambios) en 37 pacientes, de los cuales 40 (89%) fueron exitosos. Con una edad media de 58,6 años (±17,5), se intervinieron 10 hombres (27%) y 27 mujeres (73%). Las principales indicaciones fueron litiasis (37,8%), compresiones extrínsecas del uréter (28,9%) y la localización intraoperatoria ureteral (22,2%). Los intentos infructuosos fueron debidos a la incapacidad para ascender la guía/catéter en 4 casos (8,8%) o para identificar el meato ureteral en uno (2,2%). Ocho pacientes (17,8%) presentaron alguna complicación postoperatoria (7 Clavien I, uno Clavien IIIa). Ningún procedimiento se interrumpió por dolor. El análisis estadístico no encontró ningún factor predictor de éxito. El régimen ambulatorio fue 4 veces más barato. Conclusiones: La colocación de catéteres ureterales se puede realizar de forma eficaz y segura bajo anestesia local en el gabinete de cistoscopias. Este procedimiento podría ahorrar tiempo operatorio, reducir costes y minimizar los efectos secundarios de la anestesia general

Objective: To assess the outcomes of ureteral stent placement under local anesthesia for the management of multiple ureteral disorders. Methods: Retrospective study of 45 consecutive ureteral stents placed under local anesthesia from January 2015 to July 2016. Inclusion criteria were hemodynamically stable patients with urinary obstruction, urinary fistula or for prophylactic ureteral localization during surgery. Five minutes before the procedure, 10 ml of lidocaine gel and 50 ml of lidocaine solution were instilled in the bladder. A 4.8 Fr ureteral stent was placed using a 15.5 Fr flexible cystoscope under fluoroscopic control. Characteristics of procedures and outcomes were analysed. Results: A total of 45 procedures (33 placement, 12 replacements) were attempted in 37 patients, of which 40 (89%) were successful. There were 10 male (27%) and 27 female patients (73%) with a mean age of 58.6 years (±17.5). Main indications for stent placement were stones (37.8%), extrinsic ureteral compression (28.9%) and surgery ureteral localization (22.2%). The reasons for failing to complete a procedure were the inability to pass the guidewire/stent in 4 cases (8.8%) or to identify the ureteral orifice in 1 (2.2%). Postoperative complications occurred in 8 patients (17.8%) (7 Clavien I, 1 Clavien IIIa). No procedure was prematurely terminated due to pain. Statistical analysis did not find significant successful predictors. The outpatient setting provided a fourfold cost decrease. Conclusions: Ureteral stent placement can be safely and effectively performed under local anesthesia in the office cystoscopy room. This procedure could free operating room time, reduce costs and minimize side effects of general anesthesia

Pulmonary vein isolation and left atrial complex-fractionated atrial electrograms ablation for persistent atrial fibrillation with phased radio frequency energy and multi-electrode catheters: efficacy and safety during 12 months follow-up.

AIMS: Ablation for persistent atrial fibrillation (AF) remains a difficult and time-consuming procedure with varying degrees of success. We evaluated the long-term effects of a novel approach for ablation of persistent AF using multi-electrode catheters. METHODS AND RESULTS: In 89 patients with longstanding persistent AF (>1 year), multi-electrode ablation was performed with a pulmonary vein ablation catheter (PVAC), a multi-array septal catheter (MASC), and a multi-array ablation catheter (MAAC) for ablation of complex-fractionated atrial electrograms (CFAE) at the septum, left atrial (LA) roof, floor, posterior wall, and mitral isthmus. Follow-up was performed at 6 and 12 months with electrocardiogram, 7 days Holter, and occasionally ambulant event recordings. Average procedure and fluoroscopy times were 112 ± 32 and 21 ± 10 min. The pre-specified endpoint of pulmonary vein isolation and LA CFAE ablation was reached in all patients. No procedural complications were observed. At 12 months after a single treatment 44 of 89 (49%) remained in sinus rhythm, including direct current cardioversion in 12 patients. At 12 months, after a redo PVAC/MASC/MAAC, an additional 6 of 15 patients (40%) were free of AF. In 18 of 89 (20%) patients AF was changed to paroxysmal. CONCLUSIONS: In this single centre study, ablation for longstanding persistent AF with the PVAC/MASC/MAAC resulted in 56% freedom of AF at 1 year after 1.2 ± 0.4 procedures. This approach is time efficient and has a favourable safety profile.
