Clinical and hormonal evaluation and sonography of the scrotum and testes were performed 1\u20132 days before the procedure. The aspiration was done using short\u2010term general anesthesia. Follow\u2010up consisted of sonographic reexamination of the scrotum and testes immediately and 1 month after the procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Intraoperative sonography with power Doppler imaging enabled good visualization of the testicular parenchyma, easy sampling, and avoidance of prominent vessels. Sufficient material was retrieved in 15 USTSA patients (94%) and 19 TSA patients (83%). No patients needed more than 4 hours' ambulatory hospitalization after the procedure. In the remaining 5 patients, aspiration failed to yield sperm, so open biopsy was performed. In those patients, postaspiration surgical exploration revealed subtunical bleeding in 3 patients after TSA but none after USTSA. Late minor complications occurred in 2 patients (13%) in the USTSA group and 7 (30%) in the TSA group. No difference was found between the 2 groups in pregnancy rate in the patients' female partners.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>USTSA is a safe and accurate method for sperm retrieval in azoospermic patients. \u00a9 2001 John Wiley &amp; Sons, Inc.
