Control of massive hematuria in idiopathic hemorrhagic cystitis after administration of conjugated estrogen.

A renal transplant patient with severe hemorrhagic cystitis of idiopathic etiology was treated initially with intravenous administration of conjugated estrogen (1 mg./kg.), followed on day 2 and thereafter with 5 mg. per day orally for 3 weeks. Hematuria decreased in intensity within 10 hours and disappeared within 48 hours. Hematuria did not recur by 6 months after completion of oral doses of conjugated estrogen. Complications or other side effects were not observed. In our experience conjugated estrogen controls hematuria in patients with idiopathic hemorrhagic cystitis and this form of treatment must be considered in this condition.

[Infiltrating transitional carcinoma of the bladder. 3. Effect of regional lymph node dissemination on the prognosis].

The evolution of 168 patients, 136 of which underwent bilateral lymphadenectomy is analyzed in this paper. In 126 cases it was possible to obtain all the data in order to define N within the T.N.M. rating. With regard to the remaining patients 10, of which we lack the anatomopathological report, and 32 which did not undergo lymphadenectomy, are included under item Nx. During follow-up, metastasis was diagnosed in 60% node-positive patients. We believe it to have been already present at the time of undergoing surgery. Survival was significantly higher in the group without node dissemination than in both negative-nodes and Nx groups. When assessing the nodular dissemination group, patients treated with 2000 rad prior to cystectomy showed higher survival rates: 36% vs 22% and 11% for groups treated with 4500 rad and no radiotherapy. respectively. Metastatic percentage, however, was lower for the group managed with surgery alone (50%) than those treated with pre-operative radiotherapy (73% and 67% with 2000 and 4500 rad, respectively), on the other side, it would seem a contradiction that a 2000 rad dosage should be more effective than a 4500 rad dosage for this group of patients, since theoretically, the latter is closer to the ideal dosage to eradicate the nodular disease. Since 3 of 5 patients have micrometastasis, which we are yet unprepared to detect, all positive-node patients should receive chemotherapy immediately after recovery from surgery.

[Traumatic sectioning of the isthmus in a case of renal fusion].

In this paper, we present a case of traumatic sectioning of the isthmus in a patient with multiple injuries, suffering from a horse-shoe-shaped kidney, which is extremely rare, according to the review of the literature which we have carried out. In view of the scanty incidence of kidney fusions and the difficulty sometimes involved in classifying them and in their surgical treatment, we shortly comment on the consequences which traumatisms may have on this kind of kidney malformation.
