A technique for transrectal ultrasound guided drainage of prostatic cysts and large cystic utricles is described using simple adaptation of equipment readily available in the transrectal ultrasound suite.
Using the puncture trajectory display generated by the ultrasound unit, the biopsy needle is manually advanced through the needle guide of the transrectal ultrasound probe. Once the tip of the needle reaches the lumen of the cystic lesion, the central trocar 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 cyst aspiration.
This technique was performed successfully in 11 patients with symptomatic cysts within the prostate, including 7 with intraprostatic cysts and 4 with cystic utricles. The fluid collection recurred in 1 patient with a cystic utricle, causing epididymal pain and orchialgia that resolved with repeat drainage.
This technique allows for easy, successful drainage of symptomatic prostatic cysts in an outpatient setting without specialized equipment or anesthesia.
描述一种经直肠超声引导下前列腺囊肿及大囊性尿道球腺囊肿引流技术，该技术只需对经直肠超声检查室中现有的设备进行简单改装即可。
利用超声设备生成的穿刺轨迹显示，将活检针经直肠超声探头的针导向器手动推进。一旦针尖到达囊性病变的腔内，将针的中心套管从外套管中取出，并将静脉输液管插入套管的开口处。将注射器连接到延长管的另一端，以便进行囊肿抽吸。
该技术在11例有症状的前列腺囊肿患者中成功实施，其中包括7例前列腺内囊肿患者和4例囊性尿道球腺囊肿患者。1例囊性尿道球腺囊肿患者出现积液复发，导致附睾疼痛和睾丸疼痛，经再次引流后缓解。
该技术可在门诊环境中轻松、成功地对有症状的前列腺囊肿进行引流，无需特殊设备或麻醉。
