Review of surgical outcomes of patient who have undergone surgery for uterovaginal anomalies. Case notes of patients would be reviewed and data would be gathered for statistical analysis.
Uterovaginal anomalies are congenital malformations of the female reproductive tract, including hymenal, vaginal, cervical and uterine anomalies. The incidence could be as high as 7% in females1. These anomalies can occur alone or in association with other anomalies such as renal anomalies.
There could be variable consequences from these malformations, some are asymptomatic while some may have various symptoms.
It is important to be aware that obstructive uterovaginal anomalies, examples including imperforated hymen and obstructive hemivagina and ipsilateral renal anomaly (also known as OHVIRA), may present after puberty, with symptoms including amenorrhoea, dysmenorrhea, pelvic pain etc. These are conditions that should be managed. Patient may require interventions. Surgery is the principal management for obstructive anomalies, dependent on the types of obstruction. Types of surgeries ranges from simple surgical procedures to complex surgeries that require multidisciplinary input.
Post-operatively patients should be offered follow up for monitoring in view of the risk of stenosis that may require ongoing dilation or additional surgical management.
There are limited studies on the post-operative outcomes for uterovaginal anomalies, so this study aims at reviewing and comparing the different outcomes after initial surgery.
This is a retrospective observational study. Electronic and paper clinical records of all patients who attended the Prince of Wales Hospital, Alice Ho Miu Ling Nethersole Hospital and North District Hospital with the diagnosis of uterovaginal anomaly will be reviewed, data collected will be input and analyzed using different statistical analysis tools. Data between 1.1.2000 and 31.12.2023 will be reviewed retrospectively. No human subject will be recruited.
The aim of the study is to reviewing and comparing the different outcomes after surgery for patients who had uterovaginal anomalies

| Measure | Description | Time Frame |
|---|---|---|
| Background demographics affecting post-operative outcomes for patients with uterovaginal anomalies | Background demographics including age at diagnosis, age at operation, difference in age between menarche and diagnosis/ operation, history of previous abdominal or reproductive tract surgery, menstrual cycle will be reviewed. Categorical data will be analyzed with Chi square or Fisher's exact test. Continuous data will be analyzed with t test and ANOVA test. The significance level is set at 0.05. |
