Changes of testicular blood flow after vasectomy: Assessment by color Doppler ultrasound resistive index measurement

Objective: The objectives of this study were to evaluate the testicular blood flow in patients after vasectomy by use of color Doppler ultrasound resistive index measurement. Patients, subjects and methods: The study included 50 healthy men scheduled for vasectomy. Patients were assessed before and 3 and 6 months after surgery. Both testes were examined using color Doppler ultrasound with a linear array 15MHz transducer (Acuson, Sequoia). The Resistive Index (RI) of the testicular artery were measured at two locations: at the convoluted aspect (spermatic cord) and intratesticular (close to the rete testis). Addi…
