What are the complications and treatment options for pelvic floor dysfunction?

Pelvic Floor Dysfunction: Complications and Treatment

Major Complications

Pelvic floor dysfunction leads to significant morbidity through urinary incontinence, pelvic organ prolapse, fecal incontinence, defecatory dysfunction, sexual dysfunction, and chronic pelvic pain, with an 11% lifetime risk of requiring surgical intervention and a 29% reoperation rate. 1

Primary Clinical Complications

• Urinary tract complications include stress incontinence, urgency incontinence, voiding dysfunction, and recurrent urinary tract infections, with annual direct costs of $12 billion 2
• Pelvic organ prolapse affects approximately 25-33% of postmenopausal women and costs $1 billion annually in direct healthcare expenses 2
• Fecal incontinence and defecatory dysfunction result in anal incontinence with annual costs exceeding $25 million 2
• Sexual dysfunction manifests as dyspareunia, vaginismus, and pelvic floor myofascial pain 3
• Chronic pelvic pain develops from pelvic floor muscle hypertonicity and myofascial dysfunction 4

Multicompartment Involvement

• Pelvic floor abnormalities typically involve multiple compartments simultaneously, requiring comprehensive assessment rather than isolated single-compartment evaluation 1
• Complete pelvic floor failure affects all three compartments (anterior/bladder, middle/vaginal-uterine, posterior/rectal), resulting in apical prolapse with associated organ dysfunction 5

Surgical Complications

Subacute and chronic complications after pelvic floor surgery include mesh-related problems and functional deterioration:

• Mesh complications include contraction/shrinkage, mesh exposure through mucosal surfaces, mesh extrusion from body cavity, improper positioning, and migration of synthetic materials 1
• Functional complications result from devascularization and denervation, leading to voiding dysfunction, persistent pain, and dyspareunia 1
• Clinical presentations include pelvic or groin pain, infection, voiding dysfunction, and pain/dyspareunia from excessive scarring 1

Treatment Algorithm

First-Line Conservative Treatment (Mandatory Initial Approach)

Pelvic floor physiotherapy must be offered as first-line treatment for all patients with pelvic floor dysfunction symptoms, achieving 90-100% success rates with comprehensive approaches. 4

Essential Conservative Components:

• Pelvic floor (Kegel) exercises performed daily with proper technique instruction from trained healthcare personnel, involving isolated pelvic floor muscle contractions held for 6-8 seconds with 6-second rest periods, performed twice daily for 15 minutes per session, for minimum 3 months duration 4
• Patient education covering bladder/bowel dysfunction, timed voiding, adequate fluid intake, and aggressive constipation management 4
• Lifestyle modifications including proper toilet posture with buttock support, foot support, and comfortable hip abduction 4
• Cognitive behavioral therapy to decrease anxiety, discomfort, and lower urinary tract symptoms 4
• Conservative measures alone benefit approximately 25% of patients with fecal incontinence 4

Critical pitfall: Constipation management is often discontinued too early; treatment must be maintained for many months before patients regain bowel motility and rectal perception 4

Second-Line Biofeedback Therapy

Biofeedback therapy should be implemented for patients not responding to conservative measures alone:

• Real-time voiding curve visualization programs to improve flow rate 4
• Perineal EMG surface electrode feedback to teach muscle isolation 4
• Specific indication for fecal incontinence when conservative measures fail 4

Pharmacological Interventions

Medications are reserved for women with more severe symptoms or inadequate response to conservative measures:

• Low-dose vaginal estrogen for women with more severe symptoms or those not responding to conservative measures 4
• Lidocaine for persistent introital pain and dyspareunia 4

Advanced Interventions (Third-Line)

When conservative measures and biofeedback fail:

• Perianal bulking agents (e.g., intraanal injection of dextranomer) for persistent fecal incontinence 4
• Sacral nerve stimulation for moderate or severe fecal incontinence unresponsive to conservative measures and biofeedback 4
• Barrier devices for patients who have failed conservative or surgical therapy 4

Surgical Options (Fourth-Line)

Surgical intervention is considered after exhausting conservative options:

• Anal sphincter repair (sphincteroplasty) specifically for postpartum women with fecal incontinence and patients with recent sphincter injuries 4
• Specialist referral to urologist or urogynecologist for urinary incontinence, or colorectal surgeon for fecal incontinence 4

Diagnostic Evaluation for Complications

Initial Clinical Assessment

• History and physical examination form key elements, though physical examination may be limited in depicting multicompartment involvement 1
• Focused diagnostic tests include urodynamic studies for urinary incontinence and anal manometry for defecatory dysfunction 1

Imaging for Complex Cases

Radiologic imaging provides global pelvic floor information when clinical evaluation is limited:

• MR defecography (with rectal contrast and imaging during rectal evacuation) for severe or recurrent prolapse, enteroceles, and defecatory dysfunction 1
• Dynamic pelvic floor MRI (without defecation but with Valsalva maneuvers) for multicompartment assessment 1
• Transperineal ultrasound for real-time dynamic evaluation and assessment of mid-urethral sling or vaginal mesh complications 1
• Fluoroscopic cystocolpoproctography with oral, rectal, bladder, and vaginal contrast for comprehensive functional assessment 1

Post-Surgical Complication Imaging

MRI is superior for evaluating subacute and chronic surgical complications:

• MRI pelvis with IV contrast directly visualizes synthetic materials, mesh positioning, and soft tissue changes better than CT 1
• CT has poor soft-tissue resolution and cannot adequately depict synthetic materials along anterior and posterior vaginal walls 1
• VCUG assesses urinary dysfunction post-operatively, showing urethral narrowing suggesting obstruction from implanted slings 1

Treatment Success Monitoring

Success is measured by:

• Improvement in voiding and bowel diary parameters 4
• Flow rate and post-void residual urine measurement 4
• Frequency and severity of incontinence episodes 4
• Urinary tract infection recurrence rates 4

Critical Clinical Pitfalls

• Multicompartment involvement is the rule, not the exception—global assessment of all pelvic compartments allows repair of all defects during single procedure, including occult defects 1
• Behavioral or psychiatric comorbidities must be addressed concurrently for optimal outcomes 4
• Patients with refractory disease require full urodynamic studies or MRI rather than repeated failed conservative attempts 4
• Constipation management requires months of sustained treatment, not premature discontinuation 4
