Treatment of cryptorchidism. Long-term prospective study.

We have presented preliminary findings on a long-term prospective study designed to (1) assess timing of orchiopexy, (2) eliminate unnecessary abdominal exploratory surgery, and (3) determine efficacy of orchiopexy on subsequent fertility and on malignant degeneration. Some suggestions for the management of this common congenital defect can be provided, but long-term results are lacking. A significant drop-out rate from this prospective study is expected with time; therefore, large patient numbers are needed to draw any valid conclusions at the time of postpubertal reassessment.

Exstrophy of the bladder and associated anomalies.

Bladder exstrophy is a rare malformation of the urogenital tract. Its incidence is about one per 25,000-40,000 births, with a two to one ratio of males over females. No hereditary factors have been established, and it has been stated in the literature repeatedly that this defect does not occur with an increased frequency in the same family. However, Higgins reports bladder exstrophy in twins on two occasions, and twice in brothers and sisters.
