Nine cases of renal hydatid disease are reported. All diagnostic procedures are discussed and the important role of ultrasound renal scan and cyst puncture is emphasized. Although it is rare, renal secondary location has to be suspected in cases of hepatic echinococcosis and conservative surgical treatment is required to preserve renal function.
Atresia of the cervix is a rare congenital anomaly of the female genital system. We describe a girl with urinary retention caused by hematometra and other urinary malformations, for which prior operations had been performed.
2 new cases of blind-ending branches of bifid ureters in children are reported. Clinical and diagnostic features as well as treatment of this pathology are presented. The authors emphasize the differential diagnosis of blind-ending ureteral diverticula, suggesting the possibility that the single congenital diverticulum is actually a dilated blind-ending ureter.

Two new cases of Wolfram's syndrome associated with progressive urinary tract dilatation are reported. The possibility of anatomic outlet obstruction or neurogenic bladder was eliminated radiologically and urodynamically. Dilatation of the urinary tract was considered to be a consequence of high diuresis associated with diabetes insipidus. A very important improvement in bilateral urinary tract distension was achieved with bladder drainage while dDAVP therapy dramatically decreased the daily urinary output. A review of diabetes insipidus and its urological implications is presented.

Endodermal sinus tumor (EST) of the ovary is a germ cell tumor that is now recognized more frequently than in the past. Since problems concerning natural history, prognosis and therapy of these neoplasms are not entirely resolved, it should be underlined the need to report new cases. The authors describe four cases of EST with reference to serial alphafetoprotein determination by radioimmunoassay; they also emphasize the importance of this technique as a very sensitive method in monitoring therapy and in detecting recurrences of disease even before any clinical evidence.
