Here is some helpful infor about the post op course for no-scalpel vasectomy
POSTOPERATIVE CARE — The dressing and scrotal support are maintained for at least 48 hours after surgery. An ice pack intermittently applied to the scrotum for 48 hours also helps decrease discomfort and swelling.
Significant post-procedure pain is common occurring in up to 30 percent of patients but is usually self limited. Acetaminophen or ibuprofen usually provides sufficient analgesia, although occasionally narcotic analgesics are necessary.
Postoperative instructions should be reviewed with the patient. Mild pain, swelling, and bruising are normal for the first two to three days and blood in the ejaculate is common and will typically clear after three to four days. The patient should call for increasing pain, bleeding from the incision site, fever, or significant scrotal swelling.
Bed rest or quiet activity is recommended for the first 24 hours following a vasectomy. The patient may return to light work in two to three days, but should refrain from heavy work, sports, or lifting for one week.
Sexual activity is avoided for one week. The patient and his partner should be reminded to use an alternate method of contraception until semen analysis has confirmed absence of sperm (azoospermia) in the ejaculate. Since sperm are stored along the entire vas deferens and in the seminal vesicle, interruption of the vas does not result in immediate sterility and several ejaculations are required to evacuate all of the sperm.
