RESUMEN
Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.
RESUMEN
Objective: To investigate the therapeutic efficacy of double-J catheter in treatment of renal tuberculosis(TB) and in rescuing the structure and function of the kidney. Methods: Thirty-four patients with renal TB (22 combined with single side hydronephrosis) were divided into 2 groups randomly. Group A were treated with antituberculous therapy and group B with antituberculous therapy combined with pre-treatment with double-J catheter. All 34 patients were followed up for 3 months and were re-examined. Results: The results of B ultrasound, intravenous urogram (IVU), CT and isotope nephrogram were comparable between the 2 groups before treatment, and the results were significantly different between the two groups after 3 months' drug treatment (P<0.05). The results of routine urine tests, ESR and the positive rates of urine ABF were not significantly different between the 2 groups (P<0.05). Nephrectomy was performed in 21 cases, with 15 cases(88.2%) in group A and 6 cases(35.3%)in group B (P<0.05). Conclusion: Pre-treatment with double-J catheter in the diseased side of patients with renal TB can better preserve the structure and function of the kidney, and can help to lower the rate of nephrectomy.
