title: Loupe-assisted modified one-layer vasovasostomy.
abstract: Several studies indicate that microsurgical modified one-layer vasovasostomy is comparable to the two-layer anastomosis with respect to patency and pregnancy rates. The objective of this study was to determine the feasibility and result of modified one-layer vasovasostomy under loupe magnification only. Thirty-two patients aged 28 to 64 years (mean 41.3 +/- 6 years) underwent vasovasostomy at CGMH from July 1997 to June 2002, with all operations being a modified on-layer anastomosis created with the aid of a 3 x loupe. The estimated duration of vasectomy ranged from 4 months to 27 years, with a mean of 9.2 +/- 4.8 years. Postoperative semen analysis and pregnancy were examined. Each patient was followed up at 1,4, and 12 weeks postoperatively. The total operation time ranged from 118 to 228 minutes (average 150 +/- 35 minutes). There was no operation-related complication such as hematoma or wound infection. The patency rate was 89% (25/28), and the pregnancy rate at 2 years or more of follow-up was 39% (11/28). The patency and pregnancy rates were similar to those obtained in most studies of microsurgical vasovasostomy. For uncomplicated vasectomy reversal, this simple loupe-assisted modified one-lyer vasovasostomy seems to provide an adequate anastomosis.
