[Recurrent cystitis and crenotherapy. 302 cases].

This article analyzes a series of 302 female patients prone to cystitis. The fact that these women were seen in a urological crenotherapy center highlights the very evolutive nature of the disease. The high rate of E coli present in the urine should be noted. Most of the women had a normal intravenous urogram and a normal endoscopy. The "classic" causes are rarely responsible for attacks of cystitis, but sexual intercourse and pregnancy seem to play a part. Several of the women took estroprogestative pills, or wore an intra-uterine device. The rate of bowel symptomatology-colopathy or constipation--should be noted. The article assesses the evolution of cystitis before and after crenotherapy at La Preste.
