Spontaneous peripelvic extravasation associated with primary ureteral tumor: a case report

A case of spontaneous peripelvic extravasation associated with primary ureteral tumor is reported. A 56-year-old woman presented with left flank pain. Excretory urogram and abdominal computed tomographic (CT) scan demonstrated left hydronephrosis with extravasation of contrast materials around the renal pelvis. Retrograde pyelogram showed the filling defect in the left upper ureter. Under diagnosis of ureteral tumor, total nephroureterectomy was performed. Histological findings revealed transitional cell carcinoma. 80 cases of spontaneous peripelvic extravasation in Japan were reviewed and discussed briefly

Incontinent urinary diversion

1)膀胱癌に対する膀胱全摘除術時に尿路変更として, 回腸導管を188例に, 尿管瘻を49例に行った.2)術後30日以内の死亡はなかった.3)術後の早期合併症は, 回腸導管94, 尿管瘻18, 晩期合併症は, 回腸導管85, 尿管瘻23に認められた.合併症を認めなかったのは, 回腸導管49, 尿管瘻14であった.4)回腸導管の術後早期合併症は, 創感染(29%), 消化管疾患(13%), 上部尿路疾患(12%)が多くみられ, 晩期合併症は, ストーマの異常(26%), 上部尿路疾患(14%), 肝炎(13%)が多くみられた.5)回腸導管はWe analyzed 237 patients who underwent total cystectomy with ileal conduit urinary diversion or cutaneous ureterostomy at the Center for Adult Diseases, Osaka. One-hundred and eighty-eight patients underwent ileal conduit diversion and 49 patients underwent cutaneous ureterostomy. No patient died within 30 days after the operation, but two patients who underwent ileal conduit diversion died of postoperative complications within 2 months. Early complications occurred in 94 patients (50%) in the ileal conduit group and in 18 patients (37%) in the ureterostomy group. Late complications occurred in 85 patients (45%) in the ileal conduit group and in 23 patients (47%) in the ureterostomy group. Frequent early complications in the ileal conduit group were wound infection (29%), and intestinal complications (13%) which included ileus and upper urinary tract complications (12%). The most frequent late complications were stomal complications (26%) which included peristomal dermatitis stomal stenosis, parastomal hernia, and stomal prolapse, and upper urinary tract complications which were noted in 27 patients (14%)

Clinical results of total prostatectomy

1988年までの27年間に進行癌を含む63例の前立腺癌に対し全摘除術をおこなった.術前治療, 去勢術あるいは所属リンパ節郭清術の併用有無別に再発, 癌死, 生存成績について検討した結果, 補助療法を加えた全摘除術は臨床的早期癌や進行癌に対して優れた成績を示した.症例に応じた適切な補助療法の選択が今後の課題であると考えるRadical surgery was administered to 63 patients with prostatic carcinoma, of whom 48 were put under total prostatectomy, 13 under cystoprostatectomy and 2 under pelvic exenteration. Adjuvant therapy was given in three forms: pretreatment to 31 patients, castration to 44 patients and pelvic lymphadenectomy to 39 patients. The 7 patients in stage A survived without carcinoma. Of the 25 patients in stage B, recurrence was seen in 7 patients but there were no deaths and the 5- and 10-year cumulative survival rates were both 86%. Of the 24 stage C patients, 8 developed recurrence, 4 died with the disease, and the 5 and 10 year cumulative survival rates were 82% and 55% respectively. There were 7 stage D patients, of whom 3 developed recurrence and 2 died, and these patients had a 5 year cumulative survival rate of 86%. The results demonstrated that total prostatectomy with suitable adjuvant therapy is useful for advanced carcinoma as well as clinically early stage carcinoma

Studies on the Properties of Elastmer : I. A Consideration on the Interrelation between Viscoelastic and Dielectric Behavior of Polyurethane Elastmers

分子量の揃ったポリエステル型グリコールのうち,代表的なもの2種と,ポリエーテル型グリコールのうち代表的なもの2種を夫々選び,ワンショット溶液重合法でポリウレタンエラストマーを合成し,応力緩和,動的粘弾性などの力学緩和挙動と電気的な誘電緩和挙動をしらべ,緩和の活性化エネルギーから両者間に或る程度の対応付けが可能なことを見出した

Studies on Viscoelastic Behavior and Dielectrical Nature of Polyurethane Elastomers

分子量のそろったポリエステル型グリコールとポリエーテル型グリコールのうち,それぞれ代表的なものを2種類づつ選び,プレポリマー法でポリウレタンを合成し,応力緩和や動的粘弾性のような力学緩和挙動と電気的な誘電緩和挙動を調べた.その結果,両緩和の活性化エネルギ-から両者間にある程度の対応づけが可能なことを見い出し,また,第1報のワンショット法で合成したものと比較して重合法による物性への差違はほとんど認められなかった

ガリウム67が腎に集積した興味ある1例

腹部超音波検査で両腎の実質全体が不規則な高エコー像を呈するが腫瘍エコーは無く両腎実質のび漫性病変と考えられる症例において,クエン酸Ga-67(67Ga)静注3日後のシンチグラムにおいて両腎に淡いび漫性集積を認めた｡Tc-99m-DTPA(DTPA)によるRIアンギオグラムとレノグラムでは両腎への血流分布は正常で排泄遅延も認められなかった｡腎生検による病理所見でループス腎炎が証明された
