Study hypothesis
To study and compare the effect of 2 different indwelling ureteric stents on patients symptoms and quality of life. Ureteric stents need to be stuff enough for east of insertion and soft enough for increased comfort whilst in situ. Previous studies have shown that ureteric stents cause side effects in the majority of patients. We aim to assess the difference between side effects with the present stent compared to a newer developed stent. The main objective is to see whether either stent is superior with regard to the frequency and severity of side effects.

Urological and Genital Diseases:
Intervention
Informed written consent will be obtained from 100 prospective patients. Pre stent symptom questionnaire will be completed pre-procedure. Each patient will be randomised to receive either the Bard Inlay stent of the Microvasice Polaris stent. The type of stent used will be blinded from the patient and the researcher recording information. Once the stent has been indwelling for one week, the stent in situ questionnaire will be completed. Following removal of the stent the post stent questionnaire will be completed. On completion of the questionnaires, comparative scores from the 2 groups will undergo statistical analysis.
