Objectives: To determine the side effects associated with ureteral stents and their impact on sexual function and quality of life.

Methods: Symptom questionnaires were administered to 135 consecutive patients with unilateral ureteral stents. The questionnaire addressed irritative voiding symptoms, flank pain, hematuria, fever, loss of labor days, anxiety, sleep impairment, decreased libido, erectile dysfunction, dyspareunia, painful ejaculation, and a subjective overall impact on quality of life. The items were graded from 1 (minimal or no symptoms) to 5 (maximal symptoms). The patients were seen and questionnaires filled at 2 weekly intervals following stent insertion until stent extraction. Following removal of the stent, stent patency, impaction and migration rates were determined. Admissions to hospital and ancillary procedures to retreive stents were noted.

Results: The findings presented refer to questionnaire items scoring 3 or more. Dysuria, urinary frequency and urgency were reported by 40%, 50% and 55% of the patients, respectively. Flank pain, gross hematuria or fever was reported by 32%, 42% and 15% respectively. Among working patients, 45% lost at least 2 labor days during the first 14 days, and 32% were still absent from work by day 30. A total of 435 labor days were lost in the first month. Anxiety and sleep disturbance were reported by 24% and 20% respectively, and 45% of patients reported impairment in their quality of life. Decreased libido was reported by 45%, and sexual dysfunction by 42% of men and 86% of women. Stent removal necessitated ureteroscpoy in 14 patients (10.5%), due to upward migration in 11 (8.2%) and incrustration and impaction in 3. Spontaneous stent expulsion occurred in one patient. Forty-six (34%) stents were obstructed at the time of removal. Obstructed stents were associated with a longer mean dwell time as compared to the whole population, 75 versus 62 days respectively (P = 0.04).

Conclusions: Ureteral stents are associated with frequent side effects and significantly impact on patient quality of life. Our findings should be considered when deciding on ureteral stent insertion and dwell time.

Background: The indication for aortic valve replacement in patients with significant aortic stenosis is symptomatology. Aortic stenosis may be associated with bleeding from colonic angiodysplasia, resulting in anemia. Persistent anemia in such patients, despite lack of an identifiable source of bleeding, is not considered an indication for valve replacement.

Objectives: To report our experience with two elderly female patients who suffered from severe asymptomatic aortic stenosis, low levels of large von Willebrand factor multimer (10% and 5% respectively) and persistent anemia requiring multiple blood transfusions.

Methods: Both patients underwent an intensive work-up, but a source of bleeding could not be identified. Aortic valve replacement was performed in both patients.

Results: Aortic valve replacement abolished the need for further blood transfusions during a follow-up period of 20 months with normalization of the vWF[1] multimer level (20% and 30% respectively).

Conclusion: We suggest that aortic valve replacement be considered in selected patients with severe, otherwise asymptomatic aortic stenosis, who suffer from persistent anemia requiring multiple blood transfusions, lack an identifiable source of bleeding and have low levels of large vWF multimers.

Background: In the emergency department the physician is often confronted with the decision of where to hospitalize a patient presenting with chest pain and a possible acute myocardial infarction – in the cardiac care unit or in the internal medicine ward.

Objective: To characterize the clinical factors involved in the triage disposition of patients hospitalized with AMI[1] in Israel to either CCUs[2] or IMWs[3] and to determine to what extent the perceived probability of ischemia influenced the disposition decision.

Methods: During a 2 month nationwide prospective survey in the 26 CCUs and 82 of the 94 IMWs in Israel, we reviewed the charts of 1,648 patients with a discharge diagnosis of AMI. The probability of ischemia at admission was determined retrospectively by the Acute Coronary Ischemia Time-Insensitive Predictive Instrument. Co-morbidity was coded using the Index of Coexistent Diseases.

Results: The ACI-TIPI[4] score for patients admitted to CCUs or to IMWs was 76.2% and 57.7% respectively (P < 0.001). Multivariate analysis showed that young patients with a high probability of ischemia and low co-morbidity or functional impairment were more likely to be hospitalized in CCUs than in IMWs.

Conclusion: In Israel, the factors that strongly influence the initial triage disposition of patients with AMI to CCUs or IMWs are age, perceived probability of ischemia, status of co-morbid conditions and functional impairment.
