5 cases of cryptorchidisms were treated with H.C.G. during the period from Feb. 1980 to Sept. 1980. Among them, in 3 cases of bilateral cryptorchidism, H.C.G. effect was surprisingly excellent in doses of 5,500 I.U. of puberogen for 7 weeks, 6,000 I.U. for 4 weeks and 4,000 I.U. for 4 weeks respectively. In 2 cases of unilateral cryptorchidisms the H.C.G. effect was rather unsuccessful, but seemed to be meaningful. H.C.G. treatment was thought to be valuable prior to surgery especially in bilateral cryptorchidism.

In the Urological Department of Cho Ray hospital 1n 1998, 10 cases with non-palpable testis were operated. The lowest age of patients was 6 years old, the highest age was 27, the average was 14. Eight testes were in iliac fossae, 2 testes were in internal inguinal ring. Authors used technique liberating testicular vessels: elongating spermatic vessel and cord long enough to allow the testis to be placed into scrotum; creating a direct path to scrotum and thus, it is able to descend the testis into the scrotum by single stage orchidopexy, without traction on the vessels and damaging the blood supplying for testis. Six of ten cases were followed-up after operation by Doppler Ultrasonography. All receive good blood supply, no atrophy of testis was seen after operation

Study on 21 children with bilaterally or unilaterally undescended testes at Vietnam National hospital of Pediatrics. These children were from 6 months to 15 years old, 90,5% of them was ≥ 3 years old. There wasn’t any disorder in quantity and structure of chromosome in all patients. They were analysed Barr bodies and results were nagative. The results were correspond to karyotyp 46, XY All patients had coresponding in clinical diagnosis and cytogenetic test diagnosis

Reported results of HCG treatment for cryptorchism are quite variable because many factors may influence the success of the therapy. It is possible that the anatomic stratification introduces an element of selection bias into the data. 12 cases of extracanalicularly located testis were treated with HCG from December 1988 year to June 1990 year. Five of the 12 cases were cosmetically satisfactory. 3 became retractile testis which is disturbing in all that could be treated successfully but could not be satisfactory from the cosmetic point of view. Apparent hernial sac developed in 4 cases who were clinically inapparent before initiation of the hormonal therapy.

A clinical observation was made on 48 hypospadias of the in-patients in the Department of Urology, Yonsei University Hospital during the period Jan. 1966 through Dec. 1975 and the following results were obtained. 1) Of 48 hypospadias, 29 cases(60.2%) were admitted at the age of 7 or below and 19 cases(39.8%) at the ages of 8 years or more. 2) Of 48 hypospadias, 29 cases(79.2%) were peno-scrotal, 8 cases(16.6%) penile and 2 cases(4.2%) were perineal in type. 3) Cryptorchism was the most common associated anomaly and it occupied 23.3% of 30 associated anomalies. 4) Of 33 urethroplasties, 12 cases(63.1%) were succeed by Thiersch-Duplay method and 12 cases(85.7%) were succeed by Ikoma's method.

Epididymal abnormalities have long been found in conjunction with undescended testis. Undescended testis with a patent processus vaginalis are associated with epididymal abnormalities, but the incidence of epididymal abnormalities in descended testis with a patent processus has not been reported. We analyzed the patency of processus vaginalis and epididymal abnormalities of 37 patients(41 testes) treated for undescended testes and 78 patients(79 testes) treated for hydrocele. Epididymal abnormalities ranged from simple epididymal elongation, epididymal angulation, disruption between testis and epididymal tail to more complex forms, such as epididymal/vasal atresia, complete disruption between the testis and epididymal head. Among 38 undescended testis with patent processus vaginalis 27(71%) had an epididymal abnormalities compared to 12 of 37(32%)hydroceles with patent processus vaginalis(P<0,05), and 12 of 38(329b) undescended testis with patent processus vaginalis had complex epididymal abnormalities(epididymal head separation and epididymal atresia) compared to 2 of 37(5%) hydroceles with patent processus vaginalis (p<0.05). Among 37 hydroceles with patent processus vaginalis 12(32%) had an epididymal abnormalities compared to 2 of 37(5%) hydroceles with incompletely patent processus vaginalis(P<0.05). These data suggest that epididymal abnormalities probably contribute to both testicular maldescent and closure of processus vaginalis.

PURPOSE: To investigate the relationship of MIS and cryptorchidism according to the descending level of testis into scrotum, we studied expression degree of MIS by immunohistochemical analysis using anti-human MIS polyclonal antibody in testicular specimen. MATERIALS AND METHODS: MIS were stained in excised testis by trauma on each 8 patients as control group and age-matched abdominal, inguinal and prepubic cryptorchidism. The expression were classified as score 1, 2, 3 and 4 according to stained degree of percentage in randomized 16 fields(x400) under the light microscope. RESULTS: Of the degree of MIS expression in control group, 87.5% were category 3 or more. The mean score was 3.13+/-0.62. 2. Of the degree of MIS expression in abdominal type cryptorchid testis group that underwent orchiectomies, 68.7% were category 1. The mean score, 1.31 +/- 0.48, showed significant difference compared to control group(p<0.05). 3. Of the degree of MIS expression in inguinal type,56.2% were category 3 or more. The mean score, 2.63+/- 0.81, showed no significant difference compared to control group(p>0.05). 4. Of the degree of MIS expression in prepubic type, 75.0% were category 3 or more. And the mean score, 2.88+/-0.62, showed no significant difference compared to control group(p>0.05). CONCLUSIONS: Expression of MIS is different according to descending level of testis and may play a role in physiologic changes of testicular descent.
