[A case report of pulmonary arterio-venous fistula complicated with hereditary hemorrhagic telangiectasis].

A 5-year-old girl with multiple pulmonary arterio-venous fistulae was reported. Both her mother and grandmother have been diagnosed as the same disease previously. Her grandmother was treated with resection of the right basal segment for arterio-venous fistulae. Her mother is well with fistulae for more than 20 years. The patient was operated upon to enucleate two larger fistulae in segments 3 and 6 of right lung. Her postoperative course was uneventful. She was discharged from the hospital on the 22nd postoperative day. Pulmonary arteriovenous fistulae are thought to be a part of the hereditary hemorrhagic telangiectasis. Enucleation of the larger fistulae of the lung are preferable even for multiple lesions.

[A clinical study on 34 cases of urothelial cancer of upper urinary tract].

Thirty-four cases of tumor of the renal pelvis or ureter or both have been treated in our department during the past decade. The primary tumor was in the renal pelvis in 11 cases, in the ureter in 21 cases and in the ureter and renal pelvis in 2 cases, a co-existent tumor in the bladder was found in 4 cases. Seventeen patients had a tumor on the right side and 17 on the left side. The most frequent symptom was gross hematuria (70.6%) and flank pain was the presenting symptom in 7 cases (20.6%). On the intravenous pyelography, a filling defect in the renal pelvis or ureter (41.2%) and nonvisualization (53.0%) were frequent findings. Twenty-nine cases had undergone total nephroureterectomy with resection of a bladder cuff, 3 had simple nephrectomy and 2 had open biopsy alone. Postoperative radiation therapy was done in 1 case, chemotherapy in 10 cases, and 6 cases of them were treated by CAP therapy (cis-dichlorodiamine platinum, doxorubicin and cyclophosphamide). Actual and relative 5-year survival rates were 53.8% and 63.5%, and no significant difference was found in survival rate between the patients with renal pelvic tumors and those with ureteral tumors.
