ارکیوپکسی یک مرحله‌ای با قطع عروق اسپرماتیک بیضه‌های داخل شکمی غیرقابل لمس

Background: Non-palpable undescended testis (NUDT) is one of the problems encountered in pediatric surgery. As studies show, about 30-40 % of NUDT is associated with intraabdominal testis (IAT), in the case of IAT various surgical techniques have been presented for example multistage orchiopexy, orchiopexy by microvascular anastomosis orchiopexy by transaction of spermatic vessels at two stages, hormonal manipulation, in which there is no definitive success and there are several associated complications. Orchiopexy in one stage by transaction of spermatic vessels of the base of vas artery is a suitable method. Methods: This study is descriptive and prospective and was performed in Bahrami and Tehran children hospital from 2000-2001 on intraabdominal undescended testis. The patients were followed for at least 2 years. Results: From 31 patients, 70.9% were over 4 years old, 93.5% were hospitalized over 3 days, and operation time in 64.5% was lower than 3 hours. The most common early complication was vomiting (16.1%) and the most common late complication was wound infection (6.5%). There was a %80/6 chance of testicular anomaly. In follow up period, there was no decreasing in testicular size. Conclusion: One stage orchiopexy by spermatic vessel transaction is a safe technique with high success rate and low complication rate with acceptable increase in operation time and hospital stay. Based on our experience, we recommend this technique for non-palpable undescended testis.
