Levator ani complex

The group of muscles (pubococcygeus, puborectalis, iliococcygeus) that forms the main floor of the pelvis, supporting the bladder, uterus, and rectum and helping maintain continence.

Related: Pelvic floor muscle training, Puborectalis muscle, Pelvic organ prolapse
Puborectalis muscle

A U-shaped portion of the levator ani that slings around the anorectal junction, maintaining the anorectal angle that contributes to fecal continence.

Related: Levator ani complex, Anorectal angle, Fecal incontinence
Endopelvic fascia

Connective tissue layers that attach the pelvic organs to the pelvic sidewall and form supportive ligaments, such as the cardinal and uterosacral complexes.

Related: Cardinal ligament, Pelvic organ prolapse
Cardinal ligament

A band of connective tissue extending from the cervix and upper vagina to the lateral pelvic wall, providing key apical support to the uterus and vaginal vault.

Related: Endopelvic fascia, Apical prolapse
Urethral sphincter mechanism

The combination of smooth and striated muscle, vascular cushions, and connective tissue surrounding the urethra that maintains closure pressure and prevents urine leakage.

Related: Urethral hypermobility, Intrinsic sphincter deficiency, Stress urinary incontinence
Detrusor muscle

The smooth muscle of the bladder wall that contracts during voiding to expel urine and relaxes during storage to allow bladder filling.

Related: Detrusor overactivity, Urodynamic testing
Pelvic floor muscle training

A structured program of repeated voluntary contractions of the pelvic floor muscles, taught with proper technique, to improve strength and support and reduce incontinence symptoms.

Related: Levator ani complex, Stress urinary incontinence, Biofeedback
Pelvic organ prolapse quantification (POP-Q)

A standardized examination system that measures defined points on the vaginal wall relative to the hymen and assigns a stage from 0 to IV based on the most dependent point.

Related: Apical prolapse, Pelvic organ prolapse
Apical prolapse

Descent of the uterus or vaginal vault, often resulting from loss of level I suspensory support, which may coexist with anterior or posterior compartment prolapse.

Related: Cardinal ligament, POP-Q, Pessary
Pessary

A removable device inserted into the vagina to support prolapsed organs or reduce incontinence; ring and Gellhorn types are common, and regular follow-up is needed to prevent erosion.

Related: Apical prolapse, Pelvic organ prolapse
Urethral hypermobility

Excessive downward and rotational movement of the urethra during increased abdominal pressure, often associated with stress incontinence and loss of paraurethral support.

Related: Stress urinary incontinence, Urethral sphincter mechanism, Midurethral sling
Intrinsic sphincter deficiency

Poor urethral closure function caused by weakness of the sphincter mechanism itself, producing leakage with minimal exertion and often a poor response to support procedures alone.

Related: Urethral sphincter mechanism, Urethral hypermobility, Stress urinary incontinence
Stress urinary incontinence

Involuntary loss of urine occurring with physical exertion, coughing, sneezing, or other increases in intra-abdominal pressure.

Related: Urethral hypermobility, Pelvic floor muscle training, Midurethral sling
Detrusor overactivity

Involuntary bladder muscle contractions during the filling phase that may cause urgency, frequency, and urge incontinence, often seen on urodynamic testing.

Related: Detrusor muscle, Overactive bladder, Urodynamic testing
Overactive bladder

A clinical syndrome of urinary urgency, usually with frequency and nocturia, with or without urge incontinence, in the absence of infection or other obvious pathology.

Related: Detrusor overactivity, Bladder diary, Antimuscarinic therapy
Post-void residual volume

The amount of urine remaining in the bladder after voiding, measured by catheter or ultrasound; elevated values suggest incomplete emptying or retention.

Related: Urodynamic testing, Bladder diary
Urodynamic testing

A set of studies, including filling cystometry and pressure-flow analysis, that measures bladder and urethral function to clarify the cause of lower urinary tract symptoms.

Related: Detrusor overactivity, Post-void residual volume, Intrinsic sphincter deficiency
Bladder diary

A prospective patient record of fluid intake, voiding times and volumes, leakage episodes, and urgency, used to characterize voiding patterns and guide behavioral therapy.

Related: Overactive bladder, Bladder training
Bladder training

A behavioral program that uses scheduled voiding and progressive interval lengthening to improve urgency control and increase functional bladder capacity.

Related: Bladder diary, Overactive bladder
Midurethral sling

A synthetic or biologic tape placed beneath the midurethra to provide dynamic support during stress and treat stress urinary incontinence.

Related: Stress urinary incontinence, Urethral hypermobility
Anorectal angle

The angle formed between the anal canal and rectum, maintained largely by puborectalis tone, that contributes to fecal continence.

Related: Puborectalis muscle, Fecal incontinence
Fecal incontinence

Involuntary loss of solid or liquid stool or gas, resulting from sphincter weakness, nerve injury, stool consistency problems, or altered rectal compliance.

Related: Puborectalis muscle, Anal sphincter injury, Biofeedback
Anal sphincter injury

Tearing or disruption of the anal sphincter muscles, most commonly from obstetric trauma, which can lead to fecal or flatal incontinence.

Related: Fecal incontinence, Endoanal ultrasound
Endoanal ultrasound

An imaging technique using an intra-anal probe to visualize sphincter muscle integrity and identify defects, thinning, or scarring.

Related: Anal sphincter injury, Fecal incontinence
Biofeedback

A technique using sensors and visual or auditory signals to help patients learn to contract and relax pelvic floor muscles correctly during training.

Related: Pelvic floor muscle training, Fecal incontinence
Bacterial vaginosis

A polymicrobial vaginal condition marked by a shift from lactobacilli to anaerobic bacteria, causing thin gray discharge and a fishy odor with elevated vaginal pH.

Related: Nugent score, Vaginal pH
Vaginal pH

A measure of vaginal acidity, normally about 3.8 to 4.5 in reproductive-age women, that rises when lactobacilli are reduced or infection is present.

Related: Bacterial vaginosis, Vulvovaginal candidiasis
Vulvovaginal candidiasis

A yeast infection of the vagina and vulva, typically caused by Candida albicans, producing thick white discharge, itching, and vulvar irritation.

Related: Vaginal pH, Vulvodynia
Nugent score

A standardized Gram-stain scoring system that quantifies bacterial morphotypes on vaginal smear to diagnose bacterial vaginosis as normal, intermediate, or positive.

Related: Bacterial vaginosis
Vulvodynia

Chronic vulvar pain lasting at least three months without a clearly identifiable cause, often described as burning and sometimes provoked by touch or intercourse.

Related: Dyspareunia, Vulvovaginal candidiasis
Dyspareunia

Persistent or recurrent pain with attempted or completed vaginal intercourse, which may be superficial, deep, or related to pelvic floor dysfunction.

Related: Vulvodynia, Pelvic floor muscle training
Antimuscarinic therapy

Treatment using medications that block muscarinic receptors to reduce involuntary bladder contractions, easing urgency and urge incontinence; dry mouth and constipation are common side effects.

Related: Overactive bladder, Detrusor overactivity
Topical estrogen

Low-dose estrogen applied locally to the vagina to restore epithelial thickness and lubrication, improving atrophy-related dryness, urgency, and recurrent urinary tract infection.

Related: Genitourinary syndrome of menopause, Overactive bladder
Genitourinary syndrome of menopause

A collection of vulvovaginal and urinary symptoms, including dryness, burning, and recurrent infection, caused by estrogen decline after menopause.

Related: Topical estrogen, Vaginal pH
Surgical site infection prevention

Measures before and during pelvic surgery, such as appropriate prophylactic antibiotics and skin preparation, aimed at reducing postoperative wound and deep infections.

Related: Perioperative care
Perioperative care

The coordinated management of a surgical patient before, during, and after an operation, including risk assessment, prophylaxis, thromboprophylaxis, and postoperative monitoring.

Related: Surgical site infection prevention
Informed consent

The process of explaining a proposed treatment's benefits, risks, and alternatives so a patient can make a voluntary, knowledgeable decision to accept or decline.

Related: Shared decision-making
Shared decision-making

A collaborative process in which clinician and patient discuss evidence and the patient's values and preferences to choose a mutually agreed plan of care.
