[Micturition, sexual and defecation disorders in middle-aged women after pelvic fractures. A comparative study].

PURPOSE OF THE STUDY: To present the results of a three-year study on micturition, defecation, gynecological and sexual disorders in middle-aged women who sustained pelvic fractures.

MATERIAL AND METHODS: A group of 33 female patients who were treated for unstable pelvic fractures (AO types B or C) in the 2004-2009 period were evaluated (treated group) and compared with 31 women who had given vaginal birth at least once and went to see a urologist because of urinary problems in the period from 2009 to 2010 (control group). The questionnaires used in the study included ICIQ, UIQ, UDI and PISQ12 instruments. Urodynamic tests included flow cystometry, urethral pressure profile at rest and under stress and uroflowmetry. For a comparison of continuous variables of normal distribution, the t-test for independent samples was used. In the questionnaire study when responses were classified as nominal-ordinal variables, the Mann-Whitney U-test was used. Differences between the two patient groups in qualitative variables were tested by Pearson s 2 test. When the expected number of answers in contingency table was lower than 5, Fisher s exact test was used; when the number of answers was 0, Haldane s correction was employed. The results in all tests were considered significant when the level of significance was lower than 5%, i.e. p-value < 0.05.

RESULTS: The age of patients in the treated group ranged from 17 to 55 years (average, 32 years), the age in the control group was between 30 and 78 years (average, 58 years). The difference was significant (p<0.001). The control group patients had significantly more serious urination disorders than the treated group patients. Some micturition problems were reported by 25 patients (75%) of the treated group and by all patients of the control group (p<0.001). Intestinal disorders were more frequent in the treated group, in which 19 (61%) patients reported problems as against seven (21%) in the control group. Gynaecological problems involving feelings of genital prolapse had 13 (39%) control patients (p = 0.041). Sexual disorders were markedly worse in the treated group, with 16 (52%) of the patients having problems in comparison with only seven (21%) in the control group.

DISCUSSION: A comparison of patient groups composed using the method described here is disputable. The first difficulty lay with a low compliance of the treated patients, of whom only 33 underwent examination out of 52 originally enrolled. The other problem was the necessity of having an exactly defined control group of patients willing to undergo urological and gynaecological examination including urodynamic testing. The groups composed by our method were comparable only in the micturition disorder characteristic. A significantly higher age of the control group affected the comparison of defecation, gynaecological and sexual problems.

CONCLUSIONS: The results of this study showed a high occurrence of micturition, defecation and sexual disorders in middle-aged women after pelvic injury. However, the problems are usually not serious enough to make the patients seek help of a specialist. The authors recommend that these problems should be looked for by disorder-directed inquiry in the final period of pelvic fracture treatment and help of a specialist in urology, gynaecology, sexuology or proctology should be offered to the patients in whom disorders have been identified. Key words: urinary incontinence, voiding dysfunction, stool incontinence, obstipation, unstable pelvic fracture.
