Cutaneous vesicostomy revisited--the second 15 years.
The aim of this paper was to review the authors' experience with cutaneous vesicostomy (CV) over the last 15 years including indications, results, and complications of CV.


METHODS
The records of 31 patients treated by CV between 1987 and 2002 were reviewed. There were 20 boys and 11 girls. The two main primary pathologies were neuropathic bladder (19 patients) and posterior urethral valve (PUV) (7 patients). All patients underwent a Blocksom-type operation at a mean age of 23 months (range 14 days-9 years). Pre- and postoperative conventional uromanometry was performed in 18 patients (58%) and bladder function was assessed.


RESULTS
In 23 patients (74%) the CV provided a successful diversion with improvement of the upper urinary tract and/or stabilization of the renal function. In 5 patients (16%) with PUV, the improvement was temporary. In 3 patients (10%) the CV did not result in an improvement. Twenty-four patients underwent CV closure after a mean duration of 23 months (range, 1 month-7 years) of diversion. In 2 patients with myelomeningocele (MMC) and severe somato-mental developmental delay, CV was not closed and is being considered as a permanent treatment option. Urodynamic studies in 5 PUV patients showed impaired compliance and high intravesical pressure following a successful valve ablation and closure of CV. In the neuropathic bladder group the bladder function improved following closure of CV and commencement of anticholinergic medication and clean intermittent catheterization (CIC). Our augmentation ratio in the neuropathic bladder group was 22%. Complications of CV included: stenosis in 7 patients (22%), prolapse in 2 (6%), and cellulitis in 2 (6%). The revision rate was 16%.


CONCLUSIONS
In young infants CV had a less favourable result in the PUV patients than in cases with high-pressure neuropathic bladder with upper tract dilatation and severe urinary tract infection (UTI), where CV provided decompression and prevented deterioration of the renal function. Cutaneous vesicostomy has stood the test of time in our changing paediatric urological practice and it remains a valuable weapon in the armoury of paediatric urologists in selected patients.
