Pathogenesis and treatment of postcoital cystitis: are our approaches correct?

Aim. To study the pathogenetic factors in the development of postcoital cystitis and the efficiency of extravaginal transposition of the urethra. Materials and methods. Literature data and our point of view on the causes of postcoital cystitis are described. Case histories of 438 patients aged 18 to 61 (mean 24±1.3) were analyzed. The efficiency of extravaginal transposition of the urethra for the prevention of recurrence of postcoital cystitis was evaluated. Results. The long-term results of operations in 315 patients were studied. A positive effect was noted in 297 (94.3%), which means the complete recovery or reduction in the frequency of cystitis to 2 or less times a year, while complete recovery occurred in 214 patients. In 18 (5.7%), the surgical procedure was ineffective, which required repeated interventions. Discussion. According to our observations, the external opening of the urethra is located in patients with postcoital cystitis and in healthy women at the same level - before the introitus. During sexual intercourse, everyone experiences vestibulo-vaginal frictional dislocation of the urethra, however, exacerbations of the inflammatory process in the bladder occur only in some females, which is associated with the multifactorial nature of the disease. Conclusion. Postcoital cystitis develops as a result of a complex of factors, the most significant ofwhich are the state of the vaginal microflora, the virulence of uropathogenic bacteria, the anatomical features of the urethra and vagina, its narrowness with a mismatch with the penile size, the intensity and duration of sexual intercourse, severe, complicated childbirth and surgical procedures in this area. Performing extravaginal transposition of the urethra according to Komyakov demonstrated high efficiency in the prevention of recurrence of postcoital cystitis.
