Objectives: To present a modified microdot technique of microsurgical vasovasostomy that facilitates precise suture placement. To determine the outcome of a multilayer microsurgical vasovasostomy (VV) employing the modified microdot technique in terms of patency and pregnancy rate.

Methods: Fifteen consecutive men who underwent modified microdot technique for microsurgical
VV in our institution performed by a single surgeon were reviewed. Data gathered were patient's age, BMI, over all operative time and complication rate, patency and pregnancy rate.

Results: A total of 15 patients underwent 2-layer microsurgical VV. The mean age 49.35 � 5.45 years old, BMI 29.69 � 4.62 kg/m2, operative time 220 � 47minutes, hospital stay 1.5 � 0.5 days, 0% complication, 87% patency rate, and 60% over all pregnancy rate.

Conclusion: The modified microdot technique ensures precision in suture placement and facilitates the anastomosis of vasal lumens of discrepant diameters by exact mapping of each planned suture. The microdot method separates the planning from the placement. Clinical outcome of our multiple layer modified microdot technique in microsurgical VV is comparable with current contemporary studies.
