Gosling's interpretation of the male lower urinary tract. T, trigone; D, detrusor
muscle; DT, deep trigone; ST, superficial trigone; IS, internal urethral sphincter;
P, prostatic capsule; PS, external intrinsic striated urethral sphincter; PS, periurethral
striated muscle. (Borrowed with permission from Urology Clinic of North America.)
FIGURE 2.
Sixty-one year old man with severe urgency, frequency, nocturia, occasional urge
incontinence, and poor stream. Note high-pressure unstable contractions before voiding
(>100 cm H2O). Patient voids with high detrusor pressure and low flow rate.
FIGURE 3.
Forty-seven year old man with urinary incontinence; he had a history of low anterior
resection of the colon and subsequent urinary incontinence. Incontinence worsened
after TUR of prostate. Note steep filling cystometrogram (end-filling pressure of
200 mL, 60 cm H2O). Poor flow and intermittent pattern suggesting abdominal strain
to empty.
