Urinary incontinence after hysterectomy--three-year observational study.

OBJECTIVES: To perform a prospective evaluation of the long-term effects of hysterectomy on symptoms of urinary incontinence. METHODS: A prospective observational cohort study was performed. Preoperatively, 120 consecutive patients undergoing hysterectomy for benign conditions answered a questionnaire on symptoms associated with urge and stress urinary incontinence. Of the 120 patients, 44 underwent vaginal and 76 abdominal hysterectomy. Follow-up questionnaires were administered at 1 and 3 years postoperatively. RESULTS: Postoperatively, the questionnaire was answered by 115 (96%) of 120 patients after 1 year and by 107 (89%) after 3 years of follow-up. At surgery, the mean patient age was 49.5 years (range 32 to 78). In the abdominal hysterectomy cohort, a tendency was found for decreased episodes of urinary incontinence, although the difference was not significant. No significant changes were noted in micturition frequency. In the vaginal hysterectomy cohort, no significant changes were detectable in the symptoms associated with urge or stress incontinence, and no significant changes were noted in micturition frequency. For the entire hysterectomy group, a significant decrease occurred in stress urinary incontinence symptoms (P = 0.03). Subgroup analysis did not identify any particular risk factors for the development of urinary incontinence after hysterectomy. CONCLUSIONS: In contrast to the results of several studies, the results of our 3-year prospective study showed that total hysterectomy, independent of route, was not associated with an increase in urge or stress urinary incontinence symptoms.

Risk of urinary incontinence after childbirth: a 10-year prospective cohort study.

OBJECTIVE: To estimate prospectively the effect of first delivery on subjective bladder function and to assess the influence of subsequent deliveries and obstetric events METHODS: We performed a prospective, observational cohort study. During a 10-week period in 1995, 304 of 309 eligible primiparous women (98%) entered the study at the postpartum maternity ward and completed a bladder function questionnaire. The 10-year observational period was completed by 246 of 304 subjects (81%). RESULTS: Prevalence of moderate-severe stress urinary incontinence increased from 5 of 304 subjects (2%) at baseline to 27 of 229 (12%) at 10 years follow-up (P < .001). Prevalence of moderate-severe urinary urgency increased from 0 subjects (0%) at baseline to 31 of 229 (13%) at the 10-year follow-up (P < .001). The relative risk (RR) (adjusted for maternal age and parity) of moderate to severe urinary incontinence increased significantly 10 years after first delivery (RR 5.8, 95% confidence interval [CI] 1.2-33.7). At multivariable analysis adjusted for age and parity, stress urinary incontinence symptoms at 9 months and 5 years follow-up were independently associated with the presence of symptoms at 10 years after index delivery (RR 13.3, 95% CI 3.9-33.1 and RR 14.1, 95% CI 2.5-18.8, respectively). Number of vaginal deliveries or other obstetric covariates did not affect the risk of stress urinary incontinence or urinary urgency. CONCLUSION: Vaginal delivery is independently associated with a significant long-term increase in stress urinary incontinence symptoms, as well as urinary urgency, regardless of maternal age or number of deliveries. LEVEL OF EVIDENCE: II-2.

A three-year prospective assessment of rectocele repair using porcine xenograft.

OBJECTIVE: To prospectively evaluate clinical outcome of rectocele repair using xenograft 3 years after surgery. METHODS: Twenty-three patients who completed evaluation preoperatively and 1 year after surgery were assessed at a 3-year follow-up. Clinical examination was performed preoperatively, and at the 1- and 3-year follow-ups, with the pelvic organ prolapse quantification system. Symptom assessment was performed with a validated bowel function questionnaire including questions on sexual function. RESULTS: There were no graft-related complications during the 3 years following surgery. Preoperatively, all patients had stage II prolapse of the posterior vaginal wall and a rectocele verified at defecography. At the 1-year follow-up, 11 of 29 patients (38%) had rectocele of stage II or more, and 4 patients were reoperated. At 3-year follow-up 7 of 23 patients (30%) had rectocele of stage II or more. When including the 4 early anatomical recurrences, a total of 11 of 27 patients (41%) had rectocele of stage II or more at 3-year follow-up. Preoperatively, all patients reported varying degrees of rectal emptying difficulties and symptoms of bowel dysfunction. There was a significant decrease in rectal emptying difficulties (P < .01), sense of incomplete evacuation (P < .01), need for manually assisted defecation (P < .05), and symptoms of pelvic heaviness (P < .001) at the 3-year follow-up compared with preoperatively. Cure of rectal emptying difficulties was reported by fewer than 50% of patients. There were no significant changes in anal incontinence scores or symptoms of sexual dysfunction at the 3-year follow-up compared with preoperatively. CONCLUSION: Rectocele repair using porcine dermal graft was associated with an unsatisfactory anatomical cure rate and persistent bowel-emptying difficulties in the majority of patients 3 years postoperatively. LEVEL OF EVIDENCE: II-3.

Anatomical outcome and quality of life following posterior vaginal wall prolapse repair using collagen xenograft.

The aim of this study was to evaluate quality of life, sexual function, and anatomical outcome after posterior vaginal wall prolapse repair using a collagen xenograft. Thirty-three patients were evaluated preoperatively and at 6 and 12 months follow-up (FU). Quality of life and sexual function were assessed using a self-reported questionnaire. Prolapse staging was performed using the pelvic organ prolapse quantification system (POPQ). Preoperatively 3 patients had stage I, 26 patients stage II, and 4 patients stage III prolapse of the posterior vaginal wall. Prolapse of the posterior vaginal wall > or = stage II was observed in 7 patients (21%) at the 6-month FU and in 13 patients (39%) at the 12-month FU. Mean point Bp was reduced from -1.1 preoperatively to -2.5 at 6 months FU (p < 0.01) and -1.8 at 12 months FU (p < 0.01). Previous abdominal surgery was associated with a less favorable anatomical outcome (odds ratio: 2.0, 95% confidence interval: 1.5-3.8). There were no significant changes in sexual function or dyspareunia during the 1-year FU. Preoperatively 76% of the patients reported a negative impact on quality of life as a result of genital prolapse. There was a significant improvement in several variables associated with quality of life at 6 and 12 months FU. Posterior vaginal wall prolapse repair using a collagen xenograft was associated with an unsatisfying anatomical outcome at 1-year FU although several quality of life-associated variables affecting psychosocial function were improved. Improvement was not restricted to postoperative restoration of vaginal topography, and previous surgery had a negative effect on anatomical outcome.
