Objective To compare the prescrotal orchiopexy and traditional inguinal orchiopexy in the clinical treatment of children with low cryptorchidism.Methods Seventy-two patients(78 testes)who underwent orchiopexy in our hospital during March 2006 to May 2011 were retrospectively analyzed.And the undescended testis could be manipulated beyond the external inguinal ring under anaesthesia.Matching conditions were age differences among 3 months,same preoperative testicular positioning,same surgeon and same side.Using the paired study of 1 to 1,all the patients were divided into 2 groups: prescrotal orchiopexy(group A)and the traditional inguinal orchiopexy(group B),each group included 36 patients(39testes).Mean age was 5.4 years(group A)and 5.5 years(group B).The time of operation and restore standing,success rate and complications,including hernia,hydrocele,testicular atrophy and ascent were compared between the 2 groups.Results All the patients were successfully operated.The average surgical time for the prescrotal and inguinal groups were 33 and 41 min(P =0.0022),and average time of standing was 1.2 and 5.4 d(P =0.0003).All the patients had no wound infection.Followup ranged from 3 to 65 months.No hernia,hydrocele,testicular atrophy and ascent were identified in either group.The ratios of successful surgery were 100％ in the two groups.Conclusions The prescrotal orchiopexy is simple,safe,and effective in the cases that testis could be pushed down through the external inguinal ring.Compared with traditional inguinal approach,the advantages of prescrotal approach are shorter operative time,fewer traumas,less pain,faster recovery and cosmetic results.
