Complications of clean intermittent catheterization in boys and young males with neurogenic bladder dysfunction.

摘要

PURPOSE: We evaluate the risk for urethral lesions and epididymitis in boys with neurogenic bladder dysfunction treated by clean intermittent catheterization (CIC) for a minimum of 10 years. MATERIALS AND METHODS: The medical records of 28 males with neurogenic bladder dysfunction followed from the start of CIC until the age of 15 to 20 years were reviewed. RESULTS: CIC had been performed for a median of 16 years (range 10 to 21). Overall CIC was used for 438 years (265 before and 173 after puberty). During 76% of the years a noncoated polyvinyl chloride catheter with lubrication was used and in 24% of years a hydrophilic coated polyvinyl chloride catheter was used. The catheter size was 12C or greater in 43% of the cases. Independence from self-catheterization occurred during 37% of the CIC years. Of the patients 19 experienced at least 1 episode of difficulty inserting the catheter and/or had macroscopic hematuria on a total of 42 occasions. Major urethral lesions were seen on cystoscopy in 7 patients on 9 occasions (5 false passages, 1 superficial recess, 2 meatal stenoses, 1 urethral stricture). Major urethral lesions were not associated with puberty and did not occur during self-catheterization or with use of catheters 12C or greater. Epididymitis was seen in only a 12 year-old boy. CONCLUSIONS: The overall rate of complications was low. The incidence of major urethral lesions did not increase during puberty. Self-catheterization and 12C catheter or greater seemed to be protective against major lesions.
