Meatal strictures after transurethral prostatectomy using latex or polyvinyl chloride three-way catheters.
Because latex rubber catheters have been implicated in urethral stricture formation, the incidence of urethral strictures following transurethral prostatectomy (TUP) and subsequent catheterisation with latex rubber or polyvinyl chloride catheters was compared. A total of 84 patients with benign prostatic hyperplasia (n = 71) or prostatic carcinoma (n = 13) underwent assessment of urethral diameter and subsequent internal urethrotomy prior to TUP. Following resection, 42 patients received three-way self-retaining latex rubber catheters and 42 received similar catheters made of PVC. Catheters were removed when the urine was clear (mean time = 3 days), and no patient required recatheterisation. Urinary flow was assessed in all patients at 6, 12 and 24 weeks after surgery, and diminution of flow with submeatal stricture formation was noted in one patient who had received a latex rubber catheter, and in one who had received a PVC catheter. In this study, the composition of the catheter had no bearing on subsequent stricture formation following TUP.
