Urodynamic parameters development and complications of clean intermittent self-catheterization in Chinese schoolchildren with neurogenic underactive bladder.

ABSTRACT

OBJECTIVE: To evaluate the urodynamic parameters, development of bladder function and complications of clean intermittent self-catheterization (CIC) in Chinese schoolchildren with neurogenic underactive bladder. METHODS: Ninety-three children with neurogenic underactive bladder were successfully treated with CIC or combined with oxybutynin for two years follow-up. According to bladder compliance before CIC, they were subdivided into a normal bladder compliance (NBC) group and a low bladder compliance (LBC) group. Urodynamic parameters and complications were recorded. RESULTS: At follow-up, the incidence of neurogenic detrusor overactivity was found to have significantly decreased in both groups. Moreover, maximum cystometric capacity (CC) and relatively safe CC in the NBC group was significantly higher than those before CIC. However, relatively safe CC was significantly lower than that before CIC, and detrusor leakage point pressure was significantly higher than that before CIC in the LBC group. The incidences of bacteriuria, vesicureteral reflux (VUR), febrile urinary tract infections (UTI) and macroscopic hematuria were, respectively, 62, 13, 25 and 15%, and those of VUR and febrile UTI in the LBC group were significantly higher than those in the NBC group. CONCLUSION: For these cases, the complications of CIC are rare, and bladder compliance seems to be correlated with the development of bladder function and complications during CIC.
