Microsurgical subinguinal varicocelectomy with delivery of the testis and ligation of gubernacular veins: Evaluation of clinical effects / 中华男科学杂志

<p><b>Objective</b>To compare the clinical effects and postoperative complications of microsurgical subinguinal varicocelectomy (MSV) with or without delivery of the testis and ligation of gubernacular veins in the treatment of varicocele.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 163 varicocele patients treated by MSV, 40 with (group A) and the other 123 without delivery of the testis and ligation of gubernacular veins (group B). We compared the operation time, postoperative complications, rate of recurrence, and semen parameters before and at 3 months after surgery between the two groups of patients.</p><p><b>RESULTS</b>The operation time was significantly longer in group A than in B (［81.1 ± 20.0］ vs ［62.3 ± 9.6］ min, P = 0.041). Sperm concentration, total sperm count per ejaculate, sperm viability, and the percentage of progressively motile sperm were significantly improved in both groups at 3 months after MSV as compared with the baseline (P < 0.05). There were no statistically significant differences in the above semen parameters between the two groups of patients with grade Ⅲ varicocele before and after surgery (P < 0.05). Scrotal edema developed in 5 cases in group A and wound infection in 2 cases in group B after MSV, but no postoperative testicular atrophy or recurrence was observed in either of the two groups.</p><p><b>CONCLUSIONS</b>MSV with delivery of the testis and ligation of gubernacular veins showed no advantages over that without in reducing varicocele recurrence and improving semen parameters, but rather involved longer operation time and a higher incidence rate of postoperative complications.</p>

Microsurgical subinguinal varicocelectomy-technique and preliminary results

INTRODUCTION@#Varicoceles represent the most common attributable cause of primary and secondaryinfertility in the male. A number of studies have established the effect of performing varicocelectomyin order to improve semen parameters. Several techniques of varicocelectomy has been described inliterature, however, the microsurgical technique has been considered as the gold standard in doingthis procedure.@*OBJECTIVES@#The study primarily aims to establish the effect of microsurgical varicocelectomy onpostoperative semenalysis when compared to baseline semenalysis. It also aimed to establish theimpregnation rate and the span at which impregnation occurs following varicocelectomy. Lastly, thestudy also describes the technique and modifications of microsurgical subinguinal varicoelectomyperformed by a single surgeon using an operating microscope and microdoppler throughout theprocedure.@*MATERIALS AND METHODS@#Microsurgical subinguinal varicocelectomy was performed on 37 patients inSLMC from June 2015 to May 2017 by a single microsurgeon (DGL). Patient age, varicocele grade,operative time, intraoperative findings, postoperative complication, and 3-month follow-upsemenalysis results were recorded and compared. Successful impregnation of the partner and thenumber of months from the operation to the successful impregnation were also recorded.@*RESULTS@#Three months postoperative semenalysis parameters were compared to the baselinesemenalysis. The total sperm motility was noted to have increased from 27.95± 15.02 to 50.95±12.60,postoperatively with p-value of 0.010. There was no significant difference observed in the totalcount, concentration, and percent immature forms. Eleven or 30% of patients were able tosuccessfully impregnate their partners in an average span of 9 months from the time of surgery.@*CONCLUSION@#In their experience, Microsurgical subinguinal varicocelectomy has improved the semenanalysis after 3 months with a 30% chance of impregnation at an average span of 9 months,postoperatively. Furthermore, the use of microdoppler ultrasound in microsurgical varicocelectomyfacilitated better identification of the testicular arteries.
