What are the complications of bladder outflow obstruction?
- Renal insufficiency
- Infection (cystitis, epididymitis)
- Urinary retention
- Bladder calculi
- Bladder diverticulum
Minimum investigations for patient with BPH?
- IPSS
- DRE
- PSA
- Serum Creatinine
- Urine flow studies
- Urinalysis
- Ultrasound KUB
Causes of obstructive LUTS?
Male
- Bladder - neck contracture (primary/post prostatectomy)
- Prostate- BPH/Ca
- Urethra - Stricture
Female
- Bladder - prolapse
- Urethra- diverticulum/cancer/stricture
What are the causes of irritative LUTS?
- Bladder
Inflammation (UTI/irradiation/carcinoma in situ)
Outflow obstruction
Detrusor instability
Neuropathic bladder
Small capacity (TB/interstitial cystitis) - PID
Define incontinence
Inappropriate involuntary voiding or leakage of urine,producing social/hygienic problems
Classify the causes of urinary incontinence
- Failure to store
- Failure to void
- Other causes (fistulas)
What are the “failure to store” causes of incontinence?
1. Bladder Involuntary contractions (OAB/detrusor hyperreflexia) Decreased capacity (TB/irradiation) Sensory urgency (UTI/calculus/ca in situ)
2. Urethral Anatomical stress incontinence Post surgery (prostatectomy) Atrophic vaginitis Radiotherapy Neurological (myelomeningocele) Prostate ca with invasion of the ext. sphincter
What are the “failure to empty” incontinence causes?
- Bladder
Neurogenic bladder(LMN)
Myogenic bladder(atonic detrusor)
Drugs (TCA)
2. Urethral Anatomic obstruction (stricture/stenosis of bladder neck/prostate) Functional obstruction (detrusor sphincter dyssinergia)
Investigations in urinary incontinence
Urine culture (suspect UTI)
Urine cytology (suspect CIS)
Ultrasound
Urodynamics
Define enuresis
Persistence of involuntary voiding beyond age of anticipated control
Bedwetting >2 months in a child older than 5 years of age
What are the most common causes of enuresis?
Developmental delay Genetic factors Sleep disorders Nocturnal polyuria Decreased capacity Psychological factors
When are no further investigations needed in a child with enuresis?
All 3 of:
Monosymptomatic nocturnal enuresis
Normal exam
Normal urinalysis
What is the treatment of enuresis?
5 areas
- General measures (decrease fluid intake at night)
- Medical (older than age 7, Desmopressin, Imipramine, Oxybutinin)
- Behavior reinforcement (star charts)
- Conditioning (enuresis alarm)
- For polysymptomatic enuresis (treat diurnal symptoms)
What is the role of PDE5 and what effect does it cause?
Breakdown of cGMP to GMP
Detumescence
How would a psychogenic ED present?
Sudden onset
Morning erections present
Associated premature ejaculation
Causes of organic ED
- Vasculogenic
- Neurogenic
- Endocrine
- Chronic systemic disease
