A feasible ambulatory mini-incision microsurgical vasovasostomy under local anaesthesia using a specially designed double-ringed clamp that simplifies surgery

<p><b>INTRODUCTION</b>In line with the effort to evaluate feasible surgical options for vasectomy reversal and to increase patients' willingness to undergo the procedure, this study reported on a technique for ambulatory mini-incision microsurgical vasovasostomy using a double-ringed clamp (i.e. Moon's clamp). This technique does not require the use of dilators, approximators and other accessory devices.</p><p><b>METHODS</b>Ambulatory mini-incision microsurgical vasovasostomy was conducted on 263 patients who satisfied the surgical eligibility requirements for vasovasostomy and the safety criteria for local anaesthesia. The operation time, details on postoperative recovery and results of the postoperative semen analysis were recorded and retrospectively analysed.</p><p><b>RESULTS</b>The mean time used to isolate the bilateral vas deferens was 25.5 minutes. All patients were discharged on the day of surgery and all patients returned to their normal activities within 24-48 hours after surgery. No haematoma or infection occurred except in one patient. Postoperative semen analysis showed that the surgery was successful in 182 (96.8%) of the 188 patients who complied with the postoperative patient instructions.</p><p><b>CONCLUSION</b>Ambulatory mini-incision microsurgical vasectomy reversal using Moon's clamp and under local anaesthesia is a surgically feasible option that offers the advantages of a low-risk operation. It also achieves successful vasovasostomy without other accessory devices and allows patients to return to their daily activities quickly with minimal complications.</p>

The effect of testicular torsion on the contralateral testis in rats / 대한비뇨기과학회지

Prepubertal male Sparague-Dawley rats were used to investigate the effects of unilateral testicular torsion on the contralateral testicular histology. All rats were divided into eight experimental group (5 animals each), one of which was used for experimental control (sham operation). We have examined contralateral testes to determine the effect of therapeutic orchiectomy or detorsion after active physical 720' torsion (six hrs., twelve hrs., twenty four hrs.) through hemi-scrotal incision, and the effect of torsion only for two weeks. The contralateral testes demonstrated significant decreased weights variously and smaller seminiferous tubular diameter in both the orchiectomy and detorsion groups compared to the torsion only group, and there was marked contralateral testicular alterations in the torsion only group compared to the control group. These studies indicate that testicular torsion will cause contralateral testicular damage, and these contralateral alterations may be caused by generalized perineal inflammatory responses rather than immunologic phenomenon.
