Define the different types of urinary incontinence
Stress: involuntary leakage of urine on effort/ exertion (e.g. coughing/ sneezing).
Urgency: involuntary leakage of urine preceded by a strong desire to pass urine. Can be caused by overactive bladder syndrome.
Mixed: a combination of these symptoms.
Investigations for urinary incontinence
Urine dipstick/ MSU - rule out infection
Frequency volume chart - record voided volume/ frequency or urination/ quantity + frequency of LUTS
Urodynamic tests e.g. cystometry - measures the detrusor muscle contraction and pressure whilst voiding, used to confirm diagnoses
Risk factors for stress incontinence
Pregnancy
Vaginal delivery
Obesity
Post-menopausal
Age
Neurological conditions e.g. multiple sclerosis
Pathophysiology of stress incontinence
Increased intra-abdominal pressure –> increased bladder pressure. Combine with weak pelvic floor support–> bladder neck slip below pelvic floor –> involuntary voiding.
Pathophysiology of overactive bladder
over activity of the detrusor muscle –> increased bladder pressure –> urgency + urge incontinence preceded by strong desire to pass urine
Management of stress incontinence
Conservative = physiotherapy + lifestyle (lose weight, reduce fluid intake)
Medical = duloxetine (SNRI)
Surgical = TVT (tension-free vaginal tape) or TOT (trans obturator tape)
Common finding on examination of patient with stress incontinence
Rectocele/ Cystocele
Management of urge incontinence
Conservative = bladder retraining
Medical = anticholinergic medication (e.g. oxybutynin), alternative = mirabegron
Surgical = botulinum toxin type A injection, augmentation cystoplasty
Caution for medical management of urge incontinence
Anticholinergic medications e.g. oxybutynin cause side effects (dry eyes, urinary retention, constipation, postural hypotension) and cognitive decline which can be problematic to the patient SO THEY SHOULD BE USED WITH CAUTION AND MIRABEGRON CAN BE CONSIDERED AS AN ALTERNATIVE.
Pathophysiology of pelvic organ prolapse
Structures of the levator ani are weakened which causes the pelvic fascia to be overstretched. As a result, the pelvic organs descend into the vagina
Types of pelvic organ prolapse
Rectocele - rectum bulges through posterior wall of the vagina
Cystocele - bladder bulges through anterior wall of the vagina
Uterine prolapse - uterus hangs down into the vagina
Vault prolapse - in patients who have had a hysterectomy, the top of the vagina (the vault) may descend into the vagina
Define rectocele
rectum bulges through posterior wall of the vagina
Define cystocele
bladder bulges through anterior wall of the vagina
Define uterine prolapse
Uterine prolapse - uterus hangs down into the vagina
Define vault prolapse
Vault prolapse - in patients who have had a hysterectomy, the top of the vagina (the vault) may descend into the vagina
Risk factors for pelvic organ prolapse
Multiple vaginal deliveries
Instrumental/ prolonged/ traumatic delivery
Obesity
Advanced age
Pelvic surgery (e.g. hysterectomy)
Clinical presentation of pelvic organ prolapse
Patient experiences dragging/ heavy sensation in their pelvis. They may have identified a lump/ mass and have to push this to initiate bowel movements.
Urinary symptoms - urgency, frequency, incontinence, retention
Bowel symptoms - constipation, incontinence, urgency
Sexual dysfunction - pain, altered sensation, reduced enjoyment
Management of pelvic organ prolapse
Conservative = physiotherapy (pelvic floor exercises) + lifestyle (weight loss, avoid high-impact exercise)
Medical = vaginal oestrogen cream + vaginal pessary
Surgical = pelvic floor repair
Purpose of vaginal pessary + types
Purpose = provide extra support to pelvic organs from within the vagina. Significantly improve symptoms non-invasively but can cause vaginal irritation and erosion long-term. Good for patients who are considering having children in the future.
Ring - sit around the cervix and hold the uterus up
Shelf/ Gellhorn - flat disc with a stem that sits below the uterus (make it challenging to have sex)
Define a genital tract fistula
Abnormal connection(s) between the bladder and vagina which creates a single, or multiple openings and causes urine to leak from the vagina
Aetiology: congenital, external trauma, radiotherapy, difficult childbirth (forceps laceration, C-section, uterine rupture), surgery (hysterectomy, ant-incontinence surgery, prolapse surgery)
CP: continuous incontinence from the vagina after a recent pelvic operation (small = watery discharge from the vagina + normal voiding)
Ix: 3 swab test, cystoscopy, urodynamics
Mx: catheter (small/ early) –> surgery
Aetiology of genital tract fistula
Congenital
Difficult childbirth (forceps laceration, uterine rupture, C-section)
Surgery (hysterectomy, anti-incontinence surgery, prolapse surgery)
External trauma
Radiotherapy
Clinical presentation of a genital tract fistula (vesico-vaginal fisutla)
CP: continuous incontinence from the vagina after a recent pelvic operation (small = watery discharge from the vagina + normal voiding)
Investigations for a genital tract fistula
3 swab test (gauze @ top/ middle/ bottom of vagina, insert catheter and blue dye into bladder, blue dye on swabs = leak)
Cystoscopy and EUA (examination under anaesthetics)
Urodynamics
Management of a genital tract fistula
Small/ diagnosed early = catheter (chance to heal itself)
Definitive = surgery
