[Cystic cystitis in children]

Cystic cystitis is a common urinary bladder disease with a histologic picture of nodular lesions of the bladder mucosa. Intralesional lymphoid proliferation due to recurrent urinary tract infection play a major role in the occurrence of cystic cystitis. It is often found together with vesicoureteral reflux and other urinary tract anomalies and urodynamic disturbances. Examination of 116 children with cystic cystitis revealed it to be associated with urinary tract anomalies, especially vesicoureteral reflux. The average age at diagnosis is 7 years. The disease often needs longterm prophylaxis for urinary tract infections, and has favorable prognosis.
