    Association of congenital megacalycosis and ipsilateral segmental megaureter (1987)

    Notes: Abstract Four cases of congenital megacalycosis associated with ipsilateral segmental megaureter in children are presented. This association has not been emphasized, although review of the English and French literature revealed eight such cases. In all cases, the concurrent entities are unilateral, with a left-sided predominance and a male prevalence. The diagnosis of megacalycosis is presumed in four of the cases by normal function and prompt emptying of the calyceal systems on diuretic renography and/or urography. The presence of normal caliber renal pelvis interposed between the dilated collecting system and the distal dilated ureter without evidence of vesicoureteral reflux implies the coexistence of ipsilateral idiopathic megaureter. The patients usually present because of urinary tract infection and/or calculus formation, but respond well to conservative therapy.

    Notes: Abstract In a collaborative study, 48 prepubertal boys with undescended testes ranging in age from 15 months to 11 years were treated with low-dose intranasal buserelin following an every-other-day programme for a period of 6 months. Urinary LH, FSH, and testosterone were not altered during the treatment period. Boys over 7 years of age experienced a slight but significant rise in testosterone at the end of treatment. Testicular descent was achieved in only 17% of boys. In the remainder, bilateral testicular biopsies were obtained during orchiopexy. Grouped analysis showed a significant increase in the number of germ cells per tubule in both unilateral and bilateral cryptorchid boys, suggesting that buserelin treatment of the testis in a cryptorchid position is capable of improving fertility potential. If time-matched controls are compared to treated boys of the same age, again a significant difference is observed indicating that buserelin treatment does increase the germ cell count.

    Germ cell counts in semithin sections of biopsies of 115 unilaterally cryptorchid testes (1987)
    Springer
    European journal of pediatrics 146 (1987), S. S25 
    Details
    ISSN: 1432-1076
    Keywords: Unilateral cryptorchidism ; Germ cell count ; Semithin sections

    Notes: Abstract One hundred and fifteen biopsies from unilateral cryptorchid prepubertal patients were embedded in Epon. Semithin sections were examined by light microscope and the germ cell count per tubule was calculated. The mean number of germ cells was normal from birth to 12 months of age and dropped below the lower limits of normal between 1 and 2 years. Germ cell counts rose considerably during the 18-months observation period with the highest counts occurring in the last 6 months. Variability in the clinical diagnosis of cryptorchidism or inherent heterogeneity in the testicular histology of cryptorchidism are possible explanations.
