Suspect uterine retroversion from examination and the clinical setting, while distinguishing an incidental position from symptomatic disease or an incarcerated pregnant uterus. Pelvic pressure, backache, painful menstruation, pain with intercourse, difficulty voiding or rectal pressure can prompt assessment, but none proves that the uterine position is the cause.
In retroversion the uterus tilts backwards as a whole; uterine retroflexion instead describes bending between its body and cervix. The two can coexist. On an appropriate pelvic examination, the uterine body may be felt posteriorly while the cervix points more anteriorly. Mobility, tenderness, a pelvic mass and the possibility of pregnancy affect interpretation. Symptoms may come from associated endometriosis, adhesions or another pelvic disorder rather than the tilt itself.[ref]
The especially important historical presentation is early or mid-pregnancy with increasing pelvic pressure and urinary retention. An enlarged backward-lying uterus can remain trapped beneath the pelvic brim, distorting the cervix and bladder outlet. Dribbling urine can represent overflow from retention, not adequate emptying. A distended urinary bladder and a posterior pelvic mass require careful assessment rather than treatment with a diuretic. A pre-1866 account of retroversion after conception emphasized retention as a principal presenting problem.[ref]
Historical treatment aimed first to empty an overdistended urinary bladder with a catheter, then to restore position where appropriate and prevent recurrence, sometimes with positional measures or a vaginal pessary. A fixed, painful or possibly pregnant mass made blind forceful manipulation particularly hazardous. Describing the aim of a period manoeuvre does not make repeated unassessed attempts at repositioning acceptable.
Modern correction: an asymptomatic retroverted uterus commonly needs no treatment. Symptoms call for investigation of their actual cause; retroversion alone does not establish infertility or explain every miscarriage. For selected symptomatic mobile cases, conservative support or a fitted vaginal pessary may be considered, while associated disease is managed on its merits.[ref] Suspected incarceration in pregnancy, especially with urinary retention, needs urgent obstetric assessment. Ultrasonography can clarify the anatomy; magnetic resonance imaging may help when the relation of the uterus, urinary bladder and cervix remains uncertain. Drainage of the urinary bladder and any attempt at reduction are specialist decisions guided by gestation, anatomy and complications. Published evidence is largely case reports and series, so a single successful method is not a universal rule.[ref]
