We report on the clinical outcome and satisfaction survey of long-term suprapubic catheterisation in patients with neuropathic bladder dysfunction. Between early 1988 and later 1995, 185 suprapubic catheters were inserted under direct cystoscopic vision. Anti-cholinergic therapy was given to all patients with significant detrusor hyper-reflexia; the catheters clamped daily for two hours and changed every six weeks. Ultrasonography and assessment of the serum creatinine were used to assess the upper renal tracts, and the results of the pre- and post-catheter video-cystometrography was used to evaluate bladder morphology, cystometric capacity, maximum detrusor pressure and the presence of vesico-ureteric reflux. There were equivalent numbers of males and females. The follow-up ranges from 3-68 months. Following catheterisation, there was a 50% reduction in the average maximum detrusor pressure, bladder morphology improved in 85% of the cases; the bladder capacity and upper renal tracts remained unchanged. Vesico-ureteric reflux was abolished in 33% of the cases. Complaints were common consisting of recurrent catheter blockage, persistent urinary leakage and recurrent urinary tract infections. There was a 2.7% incidence of small bowel injury with one fatality. However, the general level of satisfaction was high. It is concluded that suprapubic catheterisation is an effective and well tolerated method of management in selected patients with neuropathic bladder dysfunction for whom only major surgery would otherwise provide a solution to incontinence. We are encouraged to find preservation of renal function with maintained bladder volumes and reduced maximum detrusor pressures thus justifying the policy of catheter clamping and anti-cholinergic therapy in the presence of significant detrusor hyper-reflexia. However, even in expert hands this procedure is not without hazards.
