A step-by-step priority of procedures is recommended when attempting t
o restore urethral patency in an obstructed male cat. In order of prio
rity they are: (1) massage of the distal urethra, (2) attempts to indu
ce voiding by gentle palpation of the urinary bladder, (3) cystocentes
is, (4) retrograde urethral flushing, (5) combinations of 1 through 4,
(6) diagnostic radiology to determine if the cause of urethral obstru
ction is intraluminal, mural or extramural, and if absolutely necessar
y, (7) surgical procedures.
