    Indwelling catheter management: from habit-based to evidence-based practice. Smith JoAnn Mercer Ostomy/wound management Indwelling urinary catheters are used in the care of more than five million patients per year. Prevalence rates range from 4% in home care to 25% in acute care. Catheter-associated urinary tract infections account for more than 40% of all nosocomial infections and can be associated with significant complications. Clinical practices in catheter management vary widely and frequently are not evidence-based. Effective nursing measures include: identifying patients who no longer need indwelling catheters, discussing appropriate catheter alternatives, and providing patient and caregiver education. Many catheter-associated problems can be avoided by selecting a closed catheter system with a small size catheter (14 to 18 French with a 5-cc balloon), following manufacturer's recommendations for inflation/deflation, maintaining a closed system, securing the catheter, and properly positioning the drainage bag. Practices such as routine catheter irrigation should be avoided. Current recommendations related to the management of encrustation and blockage also are discussed. Providing evidence-based catheter management strategies may reduce the rate of catheter-associated urinary tract infection, catheter encrustation, and leakage as well as the discomfort and costs associated with these complications.
    [Percutaneous Fibrin Glue Injection for Persistent Urinary Leakage after Partial Nephrectomy : A Case Report]. Okada Takuya,Kono Yuka,Matsumoto Keiyu,Utsunomiya Noriaki,Tsunemori Hiroyuki,Kawakita Mutsushi Hinyokika kiyo. Acta urologica Japonica A 69-year-old man with left atrophic kidney was referred to our hospital because of a 5.7 cm solid mass in the lower pole of right kidney revealed by computed tomography for evaluation of aortic aneurysm. An open transperitoneal partial nephrectomy was performed, and final pathological diagnosis was clear cell carcinoma, grade 2, pT1b, pNx. One month postoperatively, a computed tomography revealed 16 cm retroperitoneal fluid collection which was diagnosed as urinoma due to urinary leakage from partial nephrectomy scar of the right lower calyx. Following percutaneous drainage of a 6 Fr Pigtail catheter, 6 Fr double-J ureteral stent and urethral catheter were placed, but the discharge through the percutaneous drain continued to be 700 to 1,000 ml/day. Forty-one days after drainage, two open-end catheters (5 Fr) were directed into the urinary fistula lumen through the percutaneous tract and 6 ml of fibrin glue was injected under fluoroscopic guidance. Four days later, another 2 ml of fibrin glue was injected because of a small amount of residual urinary leakage and percutaneous drainage catheter was removed. Thereafter, urinary leakage was completely cured and ureteral stent and urethral catheter were removed. 10.14989/ActaUrolJap_63_3_107
