Ultrasonography and abdominal radiography versus intravenous urography in investigation of urinary tract infection in men: prospective incident cohort study.

OBJECTIVES: To compare ultrasonography and abdominal radiography with intravenous urography in the investigation of urinary tract infection in men. DESIGN: Prospective study in two hospital departments. Radiological procedures and urological assessments performed on different days by different clinicians SETTING: District general hospital. PARTICIPANTS: Consecutive series of men (n=114) referred to the department of urology for investigation of proved urinary tract infection. INTERVENTIONS: Ultrasonography and intravenous urography of renal tract and assessment of urinary flow rate. Clinical assessment, cystoscopy, urodynamic studies, and transrectal ultrasonography with biopsy. MAIN OUTCOME MEASURES: Sensitivity and specificity of ultrasonography and abdominal radiography compared with intravenous urography. RESULTS: Important abnormalities were seen in 53 of 100 fully evaluated patients, the most common being a poorly emptying bladder (34). The combination of plain radiographs of kidneys, ureter, and bladder and ultrasonography detected more abnormalities than intravenous urography alone. No important abnormality was missed by this combination (sensitivity 100% and specificity 93%). CONCLUSIONS: Ultrasonography with abdominal radiography is as accurate as intravenous urography in detecting important urological abnormalities in men presenting with urinary tract infection. This combination is safer than intravenous urography and should be the initial investigation for such patients. Additional determination of urinary flow rate is useful for the assessment of an incompletely emptying bladder.

The check X-ray: an unnecessary investigation after hip fracture fixation?

An X-ray-based image intensification system is a necessary operative aid in many orthopaedic procedures. Technological advances have not only increased the resolution of these systems, but allow the production of thermal images. We have compared such images obtained at the time of surgery with postoperative radiographs in 80 patients who underwent closed reduction and internal fixation for proximal femoral fractures. The films were independently assessed with particular reference to fracture reduction and the adequacy of fixation. In no case did the postoperative radiograph provide additional information. We therefore suggest that a postoperative radiograph is only necessary in exceptional circumstances. This is of significance in relation to patient discomfort, morbidity and radiation exposure. It also has important financial and manpower implications.

Arteriovenous fistula after fibular osteotomy leading to recurrent haemarthroses in a total knee replacement.

We present a patient with an arteriovenous fistula of the peroneal artery acquired after a left dome tibial osteotomy with midshaft fibular osteotomy. He had subsequently had a total knee replacement on that side. The arteriovenous malformation was only diagnosed when he represented with symptoms and signs of venous hypertension with sterile recurrent haemarthroses in the left knee. Percutaneous obliteration of the fistula, by a combination of coil embolisation and balloon occlusion, cured the symptoms.

Audit of bronchial artery embolisation in a specialist respiratory centre.

OBJECTIVE: To audit the use of bronchial arteriography and embolisation for controlling haemoptysis. DESIGN: Retrospective review of radiological and clinical data. SETTING: Brompton and National Heart Hospitals. PATIENTS: 35 patients with severe pulmonary disease in whom 58 bronchial arteriograms were obtained between 1 January 1984 and 31 December 1989 with the intention of bronchial artery embolisation for controlling haemoptysis. MAIN MEASURES: Rate of technical success and cessation of haemoptysis; detailed evaluation of patients, particularly those with major haemoptysis (> 100 ml expectorated blood); and retrospective assessment of the appropriateness of the procedure in each. RESULTS: 58 procedures were performed, nine of which were unsuitable for detailed analysis. Nine procedures were for minor haemoptysis, which subsequently recurred, and 40 for recent major haemoptysis in 26 patients with cystic fibrosis (16) aspergilloma (six), bronchiectasis (three), and an unknown diagnosis (one). The median total volume of haemoptysis in the episode before the procedure was 680 ml (range 270-2200 ml). Embolisation was technically successful in 33/40 procedures, in 17 of which, however, major haemoptysis recurred within 10 days of the procedure, leaving 16 clinically and technically successful procedures in 15 patients. Five patients (three with aspergilloma, two with cystic fibrosis) died of haemoptysis despite attempted embolisation. CONCLUSION: Success rate of bronchial artery embolisation was 40%(16/40). IMPLICATIONS: Bronchial artery embolisation is probably not justified for minor haemoptysis or when performed more than one week after a major haemoptysis. Repeat arteriograms during a single period of haemoptysis are seldom useful. With these criteria 43% fewer procedures would have been performed with no loss of clinical benefit.
