Small (1-2 cm) hematomas or wound infections can develop. Large hematomas are possible from severed perivasal vessels leaking into the easily expandability scrotal tissue. These hematomas are diagnosed by physical examination and, unless they are extremely large, can often be treated with ice, rest, and expectant management.

Because the NSV technique involves pushing vessels around the puncture site and perivasal fascia rather than cutting them, the incidence of hematomas has been reduced. In China, where the NSV technique originated, the literature on NSV indicates a hematoma rate of 0.09%. A randomized controlled trial by Sokal et al in 1999 found a hematoma rate of 0.3% in the NSV group compared to 12.2% in the traditional incisional group. [12] A Chinese series of over 150,000 operations revealed an infection rate of only 0.91%. [13] Most recently, a Cochrane review concluded that NSV resulted in less bleeding, hematoma, infection, and pain, as well as shorter operation times, than the incisional method. [14]
