[Coital incontinence].

INTRODUCTION: Urinary incontinence may seriously impact quality of life, self-image and subsequently the sexual life. Beside this fact, urinary leakage can specifically occur during sexual intercourse, formally named coital incontinence, and thus lead to specific alteration of the sexual life.

AIM: To analyse the prevalence, pathophysiological mechanisms and possible therapeutic options for coital urinary incontinence.

METHODS: Related terms to urinary incontinence and sexual dysfunction were search on PubMed database.

RESULTS: Whereas at least a quarter of incontinent women have a coital incontinence, this symptom was rarely spontaneously reported. Some women had only coital incontinence (7.6 to 20% of cases). In men, urinary incontinence during sexual intercourse was mainly observed after prostatectomy in 20 to 64% of cases. Coital incontinence requires precise assessment. Indeed, it can occur whatever the phase of coitus: local stimulation (20-30%), excitement (13-18%), penetration (62.9-68%), movements back and forth, orgasm (27-37.1%). Cervico-urethral hypermobility, sphincter incompetence, urethral instability, detrusor overactivity could be the principal physiopathological mechanisms. In men, the main cause was a stress incontinence secondary to sphincter deficiency. Specific therapeutic strategies have proved their effectiveness. The rehabilitative approach (RR=0.25, CI [0.06-1.01]), medicinal (anticholinergic were effective in 59% of cases) or surgical therapeutic (slings with an efficiency of 87%) was proposed to patients.

CONCLUSION: Coital incontinence is a common and troublesome symptom. Its precise assessment may suggest a specific mechanism and thus a specific treatment.
