Hysterectomy is not associated with de-novo urinary incontinence: A ten-year cohort study

The Risk of Stress Urinary Incontinence After Hysterectomy for Uterine Fibroids

PURPOSE

We evaluated the relationship between previous hysterectomy for uterine fibroids and subsequent stress urinary incontinence (SUI).

METHODS

This study analyzed national health insurance data. The hysterectomy group (aged 40 to 59) comprised patients who underwent hysterectomy for uterine fibroids between January 1, 2011 and December 31, 2014, and the control group (aged 40 to 59) comprised patients who visited a medical facility for a checkup during the same time span. One-to-one propensity score matching was performed to balance confounders. SUI was defined as the need for SUI surgery accompanied by a diagnosis code for SUI.

RESULTS

After matching, 81,373 cases (hysterectomy group) and 81,373 controls (nonhysterectomy group) were enrolled. The mean follow-up period was 7.9 years for the cases and 7.8 years for the controls. The incidence of anti-incontinence surgery was slightly but significantly higher in the cases than in the controls (2.0% vs. 1.7%, P<0.001). Compared to the control group, abdominal hysterectomy significantly increased the likelihood of anti-incontinence surgery both before (hazard ratio [HR], 1.235; 95% confidence interval [CI], 1.116-1.365) and after adjusting for confounders (HR, 1.215; 95% CI, 1.097-1.347). In contrast, laparoscopic hysterectomy, laparoscopic hysterectomy with adnexal surgery, and abdominal hysterectomy with adnexal surgery were not associated with an increased rate of anti-incontinence surgery. The significant association between abdominal hysterectomy and an elevated rate of anti-incontinence surgery persisted even after stratifying patients by age group.

CONCLUSION

Prior abdominal hysterectomy without adnexal surgery was associated with an increased incidence of subsequent anti-urinary incontinence surgery.

Quality of Life after Risk-Reducing Hysterectomy for Endometrial Cancer Prevention: A Systematic Review

BACKGROUND

Risk-reducing hysterectomy (RRH) is the gold-standard prevention for endometrial cancer (EC). Knowledge of the impact on quality-of-life (QoL) is crucial for decision-making. This systematic review aims to summarise the evidence.

METHODS

We searched major databases until July 2022 (CRD42022347631). Given the paucity of data on RRH, we also included hysterectomy as treatment for benign disease. We used validated quality-assessment tools, and performed qualitative synthesis of QoL outcomes.

RESULTS

Four studies (64 patients) reported on RRH, 25 studies (1268 patients) on hysterectomy as treatment for uterine bleeding. There was moderate risk-of-bias in many studies. Following RRH, three qualitative studies found substantially lowered cancer-worry, with no decision-regret. Oophorectomy (for ovarian cancer prevention) severely impaired menopause-specific QoL and sexual-function, particularly without hormone-replacement. Quantitative studies supported these results, finding low distress and generally high satisfaction. Hysterectomy as treatment of bleeding improved QoL, resulted in high satisfaction, and no change or improvements in sexual and urinary function, although small numbers reported worsening.

CONCLUSIONS

There is very limited evidence on QoL after RRH. Whilst there are benefits, most adverse consequences arise from oophorectomy. Benign hysterectomy allows for some limited comparison; however, more research is needed for outcomes in the population of women at increased EC-risk.

Er:YAG laser in hysterectomized women with stress urinary incontinence: a VELA retrospective cohort, non-inferiority study

Objective: To test whether the erbium-doped yttrium aluminum garnet (Er:YAG) SMOOTH^® laser treatment efficacy on stress urinary incontinence (SUI) in hysterectomized patients is non-inferior to its efficacy in non-hysterectomized patients.Methods: In this real-world, retrospective cohort study performed in Turkey, Croatia and Italy, we enrolled a consecutive sample of 35 hysterectomized and 34 non-hysterectomized patients with SUI. We used the Er:YAG SMOOTH^® laser (Fotona, Slovenia) with a wave length of 2940 nm. The primary outcome was median reduction of SUI symptoms measured by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short-Form (ICIQ-SF) with the non-inferiority margin defined as the minimum clinically important difference of ICIQ-SF (δ < 2.52 points).Results: In hysterectomized patients, the ICIQ-SF was reduced by 5 points (95% confidence interval 3-8; p < 0.001), a reduction of 45% (95% confidence interval 36-67%). After adjustment for baseline ICIQ-SF and five covariates, the reduction of symptoms in the hysterectomized group was not inferior to the reduction in the non-hysterectomized group.Conclusion: The Er:YAG SMOOTH^® laser treatment seems to improve the symptoms of SUI in hysterectomized women not clinically relevantly less than in non-hysterectomized women. It seems that the beneficial effect of Er:YAG SMOOTH^® laser treatment for SUI in hysterectomized women is time-limited.

[Impact of hysterectomy on urinary incontinence: A systematic review]

INTRODUCTION

The impact of a hysterectomy on urinary incontinence is a controversial subject in the literature.

OBJECTIVE

To evaluate the prevalence and incidence of urinary incontinence after a hysterectomy as well as associated risk factors such as the type of hysterectomy, the surgical approach, urodynamic criteria and uterine disease.

STUDY DESIGN

We conducted a systematic review in Pubmed database with the following keywords and MeSH term: hysterectomy, urinary incontinence.

RESULTS

A total of 1340 articles were retrieved, 42 articles were selected for the final text analysis. The results of the different studies were heterogeneous. Hysterectomy seemed to increase the rate of sphincter deficiency (VLPP<60mmH₂O for 20% of cases versus 1,7% without hysterectomy, P=0.003). The vaginal route could increase the incidence of UI with OR of 2.3 (95%CI 1.0-5.2). Subtotal hysterectomy appears to increase UI with a 0,74 RR for total hysterectomy (95%CI 0.58-0.94). A radical hysterectomy with nerve conservation would preserve urinary functions, unlike pelvic radiotherapy, which is responsible for irreversible nerve damage by demyelination and bladder fibrosis.

The Onset of Urinary Incontinence in Different Subgroups and its Relation to Menopausal Status: A Hospital-based Study

BACKGROUND/AIM

Numerous risk factors have been reported to influence the development of urinary incontinence (UI). In this study, we took a closer look on the different forms of UI and tried to identify differences in regard to potential risk factors. Of special interest was the onset of UI symptoms and its relation to menopausal status.

PATIENTS AND METHODS

This was a hospital-based analysis of patients who presented with urinary incontinence in the outpatient ward of a tertiary hospital. The diagnosis of urinary incontinence was based on the subjective complaints of patients. Data concerning menopausal status, hormone replacement therapy, prior hysterectomy were assessed.

RESULTS

The mean age was 53.8 years in the SUI group, 62.7 years in the MUI group and 66.1 years in the UUI group, respectively (p<0.001). The proportion of patients with UUI was higher in the postmenopausal group, whereas the proportion of SUI was higher in the premenopausal group (p<0.001). The mean age in which complaints occurred was significantly lower in the SUI group (45.4 years) compared to the MUI (51.0 years) and UUI groups (54.7 years) (p<0.001). There was no correlation between menopausal status and onset of urinary incontinence (p=0.143).

CONCLUSION

Additional anamnestic information help further characterize the different types of urinary incontinence that can lead to an optimization of treatment options. Younger age and premenopausal status were accompanied by milder forms of UI while menopausal status itself had no influence on the onset of UI symptoms indicating that age-related changes may lead to different types of incontinence.
