Purpose: A technique for transrectal ultrasound guided drainage of pro
static cysts and large cystic utricles is described using simple adapt
ation of equipment readily available in the transrectal ultrasound sui
te. Materials and Methods: Using the puncture trajectory display gener
ated by the ultrasound unit, the biopsy needle is manually advanced th
rough the needle guide of the transrectal ultrasound probe. Once the t
ip of the needle reaches the lumen of the cystic lesion, the central t
rocar of the needle is removed from the outer cannula and intravenous
line tubing is inserted into the opening in the trocar. The syringe is
attached to the opposite end of the extension tubing, allowing for cy
st aspiration. Results: This technique was performed successfully in 1
1 patients with symptomatic cysts within the prostate, including 7 wit
h intraprostatic cysts and 4 with cystic utricles. The fluid collectio
n recurred in 1 patient with a cystic utricle, causing epididymal pain
and orchialgia that resolved with repeat drainage. Conclusions: This
technique allows for easy, successful drainage of symptomatic prostati
c cysts in an outpatient setting without specialized equipment or anes
thesia.
