Comparing clean intermittent catheterisation and transurethral indwelling catheterisation for incomplete voiding after vaginal prolapse surgery: A multicentre randomised trial

Objective To compare clean intermittent catheterisation with transurethral indwelling catheterisation for the treatment of abnormal post-void residual bladder volume (PVR) following vaginal prolapse surgery. Design Multicentre randomised controlled trial. Setting Five teaching hospitals and one non-teaching hospital in the Netherlands. Population All patients older than 18 years experiencing abnormal PVR following vaginal prolapse surgery, with or without the use of mesh. Exclusion criteria were: any neurological or anxiety disorder, or the need for combined anti-incontinence surgery. Methods All patients were given an indwelling catheter directly after surgery, which was removed on the first postoperative day. Patients with a PVR of more than 150 ml after their first void were randomised for clean intermittent catheterisation (CIC), performed by nursing staff, or for transurethral indwelling catheterisation (TIC) for 3 days. Main outcome measure Bacteriuria rate at end of treatment. Results A total of 87 patients were included in the study. Compared with the TIC group (n = 42), there was a lower risk of developing bacteriuria (14 versus 38%; P = 0.02) or urinary tract infection (UTI; 12 versus 33%; P = 0.03) in the CIC group (n = 45); moreover, a shorter period of catheterisation was required (18 hours CIC versus 72 hours TIC; P < 0.001). Patient satisfaction was similar in the two groups, and no adverse events occurred. Conclusion Clean intermittent catheterisation is preferable over indwelling catheterisation for 3 days in the treatment of abnormal PVR following vaginal prolapse surgery.
