Popis: Objective To ascertain the duration of intermittent low-friction self-catheterization (ILSC) required to cause stricture stabilization. Patients and methods Over a 4 year period, 101 patients with a median age of 62 years (range 16–85) with recurrent urethral strictures were recruited the trial. All the strictures were treated by internal urethrotomy and the patients were then randomized to perform ILSC twice weekly for either 6 months (group 1) or 36 months (group 2). Out-patient follow-up with urinary flow rate was initially at 1 month and then at 3 monthly intervals. Stricture recurrence rates were compared between the two groups. Results Of 101 patients, seven failed to attend after the first out-patient appointment. A further 21 died of unrelated disease whilst on ILSC (although 13 had been followed up for at least 24 months and so were included in the analysis). The median follow-up was 67 months (range 24–78). Ten patients in group 2, who has suffered from recurrent strictures, refused to stop catheterizing at the appointed time and all remain stricture-free on permanent ILSC, Of the remaining 76 patients, 48 catheterized for 6 months and 28 patients performed ILSC for 6 months and 28 patients performed ILSC for 12 to 36 months (nine stopped earlier than intended). Forty per cent of patients who stopped at 6 months developed a recurrence compared with 14% who catheterized for more than 12 months (P
