PURPOSE: Testicular microlithiasis (TM) is a relatively rare clinical entity of controversial significance characterized by the existence of hydroxyapatite microliths located in the seminiferous tubules. The aim of this study was to observe the natural course of changes in the calcific density of pediatric TM. MATERIALS AND METHODS: We included a total of 23 TM patients undergoing scrotal ultrasound (US) on at least two occasions from July 1997 to August 2014. We retrospectively analyzed the patient characteristics, clinical manifestations, specific pathological features, and clinical outcomes. We measured the calcified area and compared the calcific density between the initial and final USs. RESULTS: The mean age at diagnosis was 11.3+/-4.6 years, and the follow-up period was 79.1+/-38.8 months (range, 25.4-152.9 months). During the follow-up period, no patients developed testicular cancer. Calcific density on US was increased in the last versus the initial US, but not to a statistically significant degree (3.74%+/-6.0% vs. 3.06%+/-4.38%, respectively, p=0.147). When we defined groups with increased and decreased calcification, we found that diffuse TM was categorized into the increased group to a greater degree than focal TM (10/20 vs. 4/23, respectively, p=0.049). In addition, five of eight cases of cryptorchidism (including two cases of bilateral cryptorchidism) were categorized in the increased calcification group. CONCLUSIONS: Diffuse TM and cryptorchidism tend to increase calcific density. Close observation is therefore recommended for cases of TM combined with cryptorchidism and cases of diffuse TM.

PURPOSE: It is well known that testicular germ cell tumors arise with increased frequency in patients with cryptorchidism. In addition, intratubular germ cell neoplasia (ITGCN) is a precursor lesion to testicular germ cell tumor. Approximately 50% of patients with ITGCN will develop an invasive of testicular germ cell tumors within 5 years. Therefore, we evaluated that the incidence of ITGCN in postpubertal cryptorchidism. MATERIALS AND METHODS: Between January 2002 and August 2012, orchiectomy specimens from 31 postpubertalpatients (aged 12 or over) with cryptorchid testis were reviewed. The specimens were evaluated for ITGCN using immunohistochemical stains of placental-like alkaline phosphatase and Oct 3/4 with routine hematoxylin-eosin stain. Additionally, the degree of spermatogenesis was assessed using the Johnsen score. RESULTS: Mean age was 34 years (range, 17 to 74 years) at surgery. All patients were diagnosed as unilateral cryptorchidism. One patient (3.2%) of 20-year-old had ITGCN in surgical specimen with all positive markers. Histological assessment of spermatogenesis showed that mean Johnsen score was 3.42 (range, 1 to 9). Majority of patients (27 of 31) presented impaired spermatogenesis with low Johnsen score lesser than 5. CONCLUSIONS: Considering the risk of malignancy and low spermatogenesis, we should perform immunohistochemical stains and discuss preventative orchiectomy for the postpubertal cryptorchidism.

Objective:
To determine the feasibility and short-term effect of single scrotal-incision orchidopexy (SSIO) without ligation of the processus vaginalis (PV) in the treatment of palpable undescended testis (PUDT).
METHODS:
This retrospective study included 109 cases of PUDT (125 sides) and 15 cases of impalpable undescended testis (IUDT). The former underwent SSIO without PV ligation (group A, n = 53) or standard inguinal orchidopexy with PV ligation (group B, n = 56) while the latter received laparoscopic exploration (group C). We analyzed the success rate of SSIO in the management of PUDT, postoperative complications, and incidence rates of hernia and hydrocele, and compared the relevant parameters between groups A and B.
RESULTS:
The median age of the PUDT patients was 1.4 (0.6-11.0) years. Group A included 24 cases of left PUDT (2 with hydrocele), 20 cases of right PUDT (1 with hydrocele), and 9 cases of bilateral PUDT, the success rate of which was 95.1%. Group B consisted of 27 cases of left PUDT, 22 cases of right PUDT (3 with hernias), and 7 cases of bilateral PUDT. The rate of PV patency in the PUDT patients was 80.8% (101/125). Laparoscopic exploration of the 15 IUDT patients revealed 2 cases of congenital testis absence, 6 cases of testis dysplasia, all treated by surgical removal, 3 cases of staying around the inner ring, descended by inguinal orchidopexy, and the other 4 treated by laparoscopic surgery. The incisions healed well in all cases, with no testicular atrophy, inguinal hernia or hydrocele.
CONCLUSIONS
Single scrotal-incision orchidopexy without PV ligation is a safe and feasible procedure for the treatment of palpable undescended testis, which avoids the risk of inguinal hernia or hydrocele.
