Abstract

From July, 1977 to May, 1988, 148 patients of cryptorchidism had been admitted to our Department of Urology, Chonbuk National University hospital. A clinical evaluation was made on these 148 patients and a histopathological observation was combined to the 47 patients who had an operation for cryptorchidism during the period of May. 1986 to May, 1988. The results were as follows ; 1. cryptorchidism had the highest incidence rate among the anomalies of the genitourinary tracts. (32.8 %). 2. On the age distribution, 6 to 10 years old group was the most frequent (35.1%) and 11 patients (7.4%) were over 20 years old. 3. Inguinal area was the most frequent location (64%) and 28% of the cases were bilateral and the right side was more prevalent (67%). 4. Among the associated anomalies, inguinal hernia was the most common (36%) and 5 patients(3.4%) were associated with hypospadias. S. On histopathological findings of the undescended testis, the diameter of the seminiferous tubule was smaller compared to the normal descended testis and fibrosis of peritubular structure was initiated from earlier age group and the number of the spermatogonia was abruptly diminished after puberty.
