Abstract

Objetivo: Las indicaciones más habituales para la colocación de un stent ureteral son nefrolitiasis obstructivas, cirugía nefroureteral, oncología urológica, endourología, compresión ureteral extrínseca y como apoyo previo al tratamiento con LEOC. Métodos: Presentamos un caso de un varón de 77 años de edad con catéter ureteral DJ colocado durante 8 meses y con antecedentes personales de nefrolitiasis que presenta calcificación de 60 mm x 30 mm de extremo distal del mismo. Resultados: Se realizó cistolitotomía abierta y extracción del stent que solventó el cuadro. La composición del cálculo fue fosfato amónico magnésico con trazas de urato amónico y fosfato cálcico. Conclusión: En muchas ocasiones la persistencia prolongada de dicho stent, junto con antecedentes de nefrolitiasis e infección urinaria predispone a la calcificación y encrustamiento de dicho catéter ureteral, siendo necesarias técnicas de endourología, litotricia extracorpórea o cirugía abierta para la resolución de dichos cuadros. Objective: The commonest indications for ureteral stent placement are: obstructive nephrolithiasis, renoureteral surgery, urologic oncology, endourology and extrinsic ureteral compression. Methods: We report the case of a 77-year-old male patient with a DJ ureteral catheter placed for an 8-month period and history of nephrolithiasis; the stent showed a 60 mm x 30 mm calcification, on its distal end. Results: Open cystolithotomy and removal of stent resolved the clinic symptomatology. Conclusion: A prolonged indwell time of stents, as well as a history of nephrolithiasis and urinary infections may on many occasions result in calcification and encrustation of ureteral stents, and will lead to the use of endourology techniques, extracorporeal lithotripsy or open surgery to resolve these conditions.

Abstract

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, 10ml of lidocaine gel and 50ml of lidocaine solution were instilled in the bladder. A 4.8Fr ureteral stent was placed using a 15.5Fr 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., (Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.)

Abstract

Se presenta el caso de un varón de 45 años que llevaba olvidado durante 2 años un catéter ureteral doble J izquierdo. El catéter presentaba ambos extremos calcificados no pudiéndose extraer mediante cistoscopia y pinzas. Se realizaron sesiones de litotricia extracorpórea en ambos extremos consiguiéndose la fragmentación de la litiasis y posteriormente pudo ser extraído en dos trozos mediante cistoscopia y ureteroscopia. A 45 year old man with a 2 year forgotten left double-pigtail ureteric stent was referred to our hospital. Because of distal calcifications, the stent could not be removed by means of a cystoscopy. So, extracorporeal wave lithotripsies were performed and then the stent were easily removed in two fragments by cystoscopy and ureteroscopy.

Abstract

Objective: To determine the incidence of urinary tract infection in those patients that we have used an ureteral double-J stent as internal diversion after urological procedures., Material and Methods: We reviewed all the medical records of patients who had a ureteral double-J stent after a urological procedure from August 2007 to May 2013. We have analyzed the following data: age, gender, type of prophylaxis, incidence of urinary tract infection (UTI), days of internal diversion with double-J stent, surgical procedure, bacterial characteristics, bacterial sensibility to antibiotics and UTI treatment., Results: We have used 73 double-J stents as ureteral internal diversion in 67 patients with a mean age of 44.73±57.23. Surgical procedures were 50 laparoscopic Anderson-Hynes pyeloplasties in 49 patients, and 20 high-pressure balloon dilatation of the ureterovesical junction to treat primary obstructive megaureter in 15 patients; and 3 patients with ureterovesical obstruction after endoscopic treatment of vesicoureteral reflux. Forty three stents showed a bacterial colonization in cultures. Pseudomona aeruginosa was present in 9 (20.9%) stents. Only in 12 stents, bacterial colonization was sensible to antibiotic prophylaxis. Stent colonization was higher in boys and younger patients. Four patients had a febrile UTI. Incidence of UTI in younger patients that underwent HBPD of UVJ is higher., Conclusion: Bacterial colonization is frequent in double-J stents but the incidence of UTI is low. Double-J colonization is higher in younger patients. Patients that underwent HPBD have a higher risk of UTI related with ureteral double J stent., (Copyright © 2014 AEU.
