Glued Angiocatheter: A Rare Complication of Intrarenal Pseudoaneurysm Glue Angioembolization

Endovascular management of intraparenchymal renal artery pseudoaneurysms is a reasonable and effective therapeutic technique. Endovascular management preserves the maximum amount of renal tissue and reduces the potential risk of nephrectomy. We present the case of an angiocatheter that became stuck in the renal artery following the injection of cyanoacrylate glue for angioembolization of an intrarenal pseudoaneurysm.

Eosinophilic cystitis mimicking tuberculosis: an analysis of five cases with review of literature

Eosinophilic cystitis [EC] is a rare disease. It is a transmural inflammation of the bladder, predominantly with eosinophils. High index of suspicion is needed for timely intervention. EC should be kept as a differential diagnosis in patients presenting with lower urinary tract symptoms due to small capacity bladder with a negative workup for urinary tuberculosis and in patients having hematuria and negative cytology, or incidentally found bladder lesions with known risk factors. Initial treatment is conservative with removal of risk factor, anti-histaminics and steroids. Augmentation cystoplasty should be considered in patients with a small capacity bladder. These patients need a strict and long term follow-up

Efficacy of Holmium Laser Urethrotomy in Combination with Intralesional Triamcinolone in the Treatment of Anterior Urethral Stricture

PURPOSE: To evaluate the outcome of visual internal urethrotomy with a holmium:yttrium-aluminum-garnet laser along with intralesional triamcinolone injection. MATERIALS AND METHODS: Patients with an anterior urethral stricture less than 3 cm in length were evaluated by clinical history, physical examination, uroflowmetry, and retrograde urethrogram preoperatively. All patients were treated with holmium laser urethrotomy and intralesional triamcinolone (80 mg) injection under general or regional anesthesia. An 18 F urethral catheter was placed for 5 days. All patients were followed up for 12 months postoperatively by history, uroflowmetry, and if required, retrograde urethrogram or urethroscopy every 3 months. RESULTS: The mean age of the patients was 42.9 years (range, 14 to 70 years). The overall recurrence rate was 24%. The success rate in patients with strictures less than 1 cm in length was 95.8%, whereas that in patients with strictures of 1 to 3 cm in length was 57.7% (p=0.002). The outcome did not depend on age, duration of symptoms, etiology, or location of stricture. CONCLUSIONS: Holmium laser urethrotomy with intralesional triamcinolone is a safe and effective minimally invasive therapeutic modality for urethral strictures. This procedure has an encouraging success rate, especially in those with stricture segments of less than 1 cm in length.

Fragmented Pigtail Percutaneous Nephrostomy Tubes: Etiology and Management

PURPOSE: To review our experience with the management of fragmented and retained pigtail percutaneous nephrostomy (PCN) tubes and to explore the reasons for the fragmentation. MATERIALS AND METHODS: We retrospectively reviewed our institute database from January 2006 to December 2011 for patients who had undergone retrieval of fragmented PCN tubes. We assessed the preoperative factors, operative technique, and post-operative outcomes. RESULTS: A total of seven patients (4 males and 3 females) had been diagnosed with fragmented PCN tubes. The mean age of the patients was 41.5 years. Of the seven patients, five required antegrade instrumentation by way of a percutaneous tract to remove the foreign body, mostly along with stone retrieval. One patient underwent ureterorenoscopy and pneumolithotripsy for a ureteric stone along with ureteroscopic removal of the PCN fragment. Another patient underwent nephrectomy of the kidney containing the PCN fragment because it had become nonfunctioning. All patients were free of stones and symptoms on follow-up. CONCLUSIONS: A prolonged waiting period for definitive surgery, urinary infection, and associated stone disease are significant factors causing fragmentation of PCN tubes. Proper insertion techniques, regular timed changes of the PCN tube, appropriate care of the PCN tube, and early surgery for underlying stone disease are required to avoid this complication. Patients with retained PCN tubes can be managed effectively with antegrade or retrograde endoscopic techniques while definitive management of the primary pathology is carried out, without any additional morbidity.
