2022 UDS

Question 1

Explain detrusor overactivity (DO) and its key characteristics.

Answer 1

DO is an involuntary detrusor contraction during bladder filling, associated with urgency and frequency. It can be neurogenic or idiopathic, and UDS may show phasic or terminal contractions.

Question 2

How do you calculate BOOI, and what does it signify?

Answer 2

BOOI is calculated as
Pdet at Qmax
−
2
×
(
Qmax
)
Pdet at Qmax−2×(Qmax). >40 suggests obstruction, 20–40 equivocal, <20 unobstructed. It helps in diagnosing bladder outlet obstruction.

Question 3

What is the Abrams-Griffiths Nomogram, and how does it work?

Answer 3

: It’s a graphical tool used to diagnose bladder outlet obstruction in men by plotting detrusor pressure against urine flow rate. It distinguishes between obstruction, equivocal obstruction, or non-obstruction.

Question 4

Describe the diagnosis and treatment of pelvic floor dysfunction.

Answer 4

Diagnosed through UDS, showing increased EMG activity during voiding, and a closed bladder neck. Treatment may include pelvic floor physical therapy, biofeedback, and relaxation techniques.

Question 5

Explain detrusor underactivity (DU) and how it is diagnosed.

Answer 5

DU is characterized by weak or prolonged bladder contractions, resulting in poor emptying. Diagnosed through UDS with Pdet at Qmax <40 cm H2O and decreased uroflowmetry.

Question 6

DU is characterized by weak or prolonged bladder contractions, resulting in poor emptying. Diagnosed through UDS with Pdet at Qmax <40 cm H2O and decreased uroflowmetry.

Answer 6

DU is characterized by weak or prolonged bladder contractions, resulting in poor emptying. Diagnosed through UDS with Pdet at Qmax <40 cm H2O and decreased uroflowmetry.

Question 7

Explain the management and surveillance of neurogenic lower urinary tract dysfunction.

Answer 7

Includes CIC, medical therapy, onabotulinumtoxin A, and surveillance UDS in high-risk patients. Surveillance UDS is crucial for monitoring upper tract deterioration and assessing treatment effectiveness.

Question 8

Describe the management options for BOO.

Answer 8

Depending on etiology (e.g., BPH), treatment can include alpha-blockers, surgical interventions like prostatic urethral lift, or other procedures to relieve obstruction.
