[Clam ileocystoplasty for neurogenic bladder due to spina bifida]

A 24-year-old female with neurogenic bladder due to spina bifida consulted our department for further evaluation and treatment of a left renal stone. She innately voided urine by Crede's method. At the age of 15 years, intermittent self-catheterization was started because left severe hydronephrosis was found. At the age of 19 years, cystostomy was performed because of low compliance bladder and an aggravation of hydronephrosis in spite of intermittent catheterization. Thereafter, she was referred to our department for further evaluation and treatment of a left renal stone since the stone was increasing in size. First, left percutaneous nephrolithotomy was performed successfully. Secondly, clam ileocystoplasty using the ileum was carried out, followed by 1) increase of the bladder capacity, 2) improvement of the bladder compliance, 3) adequate intermittent self-catheterization, and 4) disappearance of urinous odor resulting from removal of the cystostomy catheter. Thus, the clinical effects were thought to be significant.
