【Objective】 To explore the application value of scrotoscopy in the treatment of testicular hydrocele. 【Methods】 The clinical data of 27 patients with testicular hydrocele who were successfully treated with minimal hydrocelectomy with the aid of scrotoscope (MHS group) and 32 patients with traditional open surgery (TH group) during Dec.2017 and Dec.2021 were retrospectively analyzed and compared. 【Results】 Compared with TH group, the MHS group needed shorter average operation time [(32.22±5.25) min vs.(57.34±8.71) min, P<0.01], shorter incision length [(0.95±0.15) cm vs.(5.09±0.55) cm, P<0.01], shorter hospital stay [(3.63±0.97) d vs.(4.72±0.89) d,P<0.01] and lower postoperative incision visual analogue scale (VAS) (P<0.01), and milder degree of edema on the 3rd and 7th day after operation (P<0.05), but higher recurrence rate (14.81% vs.3.13%, P=0.256) 24 weeks after operation. 【Conclusion】 Scrotoscopy is safe in the treatment of testicular hydrocele, which has the advantages of short operation time, small incision, mild postoperative incision pain, mild scrotal edema and short hospital stay, but the recurrence rate tends to be higher than that of traditional open surgery.
