[Posttraumatic functional exclusion of the kidney of nonvascular origin. Description of a case and review of the literature].

A review of published series about 56 cases with unilateral nonvisualization on excretory urography after external trauma have been described: the renal injury causing the nonvisualization was contusion in 8 patients, laceration in 13, rupture in 12 and renal pedicle in 19. The acquisition of the most important methods has allowed a total view as about minimal lesions (contusion, laceration), as rupture or fragmentation of the kidney and renal pedicle. We have evaluated 32 cases of renal traumatic injuries and we have studied one case with unilateral nonvisualization stressing the diagnostic, etiopathogenetic and therapeutic problems.

Fertility in unilateral cryptorchidism: review of 104 cases.

Testicular maldescent adversely affects spermatogenesis, therefore the primary purpose of its correction is to preserve subsequent fertility. However, many patients, even with unilateral cryptorchidism, are infertile in spite of successful prepubertal orchidopexy. Out of our 104 patients treated for unilateral cryptorchidism before puberty, a decreased sperm density (spermatic concentration less than 20 X 10(6)/ml) was observed in 64 cases (61.54%), a normal sperm count in 32 cases (30.77%) and azoospermia in the remaining 8 cases (7.69%). Both congenital and acquired abnormalities may be associated with development of bilateral testicular impairment in unilateral cryptorchid males.
