[Cryptorchidism: medium- and long-term follow-up].

ABSTRACT

AIM: Cryptorchidism represents the most frequent male genital anomaly in paediatric population and may potentially interfere with fertility and determine neoplastic testicular diseases. We wanted to evaluate the correlation between age at orchiopexy and follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels in adulthood, determining the long-term complications of surgical treatment. METHODS: Fifty-seven patients (mean age 19 years, range 18-27) surgically treated for cryptorchidism in pediatric age were included in a medium and long-term follow-up (10-19 years). We divided this population into four groups A) monolateral cryptorchidism operated on before 36 months of age (15); B) monolateral cryptorchidism operated on over 36 months (32); C) bilateral cryptorchidism operated on before 36 months (5); and D) bilateral cryptorchidism operated on over 36 months (5). All patients underwent andrological examination, testosterone, FSH and LH dosage, measurement of testicular volume and spermiogram. RESULTS: Significant different FSH levels were found between group A and C and between A and D (P<0.01), while groups A and D presented also different mean testicular volume (P<0.01). In addition group D showed an abnormal morphology of spermiogram. The main complications found in follow-up were hydrocele (17,5%), varicocele (8,7%) and epididymal cysts (3.6%). CONCLUSION: Monolateral cryptorchidism is associated with normal fertility when treated early (group A). Subjects in Group D, on the contrary, have a rise of FSH, a reduction of testicular volume and semen abnormalities. The long-term follow-up of these patients can also detect associated.
