Summary A group of 69 community patients undergoing long‐term urethral catheterisation for urinary incontinence took part in this study; 33 patients with a mean age of 70.03 years (± 16.6) received the Dow Corning Silastic catheter (16 F 10‐ml balloon) and 36 patients with a mean age of 75.61 years (± 12.6) received the Bard Biocath catheter (16 F 10‐ml balloon). Over a 16‐week period catheters were monitored every 2 weeks and changed as necessary. The Bard Biocath catheter remained in situ for an average of 89.61 days (± 35.31) and the Silastic catheter remained in situ for an average of 56.7 days (± 38.8); this difference was statistically significant. Used catheters were analysed for encrustation using scanning electron microscopy (SEM). The average time in situ for non‐encrusted Biocath catheters was 83.7 days and 25.28 days for non‐encrusted Silastic catheters. It was found that 70% of patients who received Biocath catheters preferred them to their previous catheters whereas only 30% of patients in the Silastic group preferred the trial catheter. The incidence of bypassing was 28% in the Biocath group and 52.8% in the Silastic group.
