ㅤContext to the study:
Can you tell me about a study that examined urethral stricture recurrence after CISC?
ㅤ✅ Take-home message of study:
There was no significant difference in stricture recurrence rate between patients who performed CISC and those who did not.
ㅤ Retrospective case control series
ㅤ
Study participants:
Participants
126 new patients with urethral stricture treated endoscopically between 1994 and 2001.
31 patients underwent twice weekly clean intermittent catheterisation (CISC) with 16Fr catheter,
95 patients did not.
Mean follow up 25 months
Mean age 57.7 years
Stricture recurrence defined as symptomatic stricture recurrence (Qmax<10ml/s, obstructive LUTS, and definitive diagnosis at flexible cystoscopy or urethrogram) requiring surgical intervention.
Urethral dilatation was primary treatment in 32 (25.4%)
Urethrotomy in 91 (72.22%)
Dilatation and urethrotomy in 3 patients (2.4%)
ㅤ
ㅤ
Key study outcomes:
Overall stricture recurrence = 48%
CICS: 42%
no CICS 49%
mean time to recurrence 16 months
Repeat intervention rate per patient
CICS mean 2.6/recurrent stricture
No CICS 3.4/recurrent stricture
ㅤ
ㅤ
Study Limitations:
Small numbers in CICS group - repeat intervention rate different yet recurrence rate isn't - raising question of whether different outcomes would be observed in larger sample size
Single centre
No long term follow up
