[Electrohydraulic lithotripsy of upper urinary tract calculi].

Electrohydraulic lithotripsy (EHL) was employed for the treatment of 35 patients with upper urinary tract calculi. The stones in 14 patients with renal and upper ureteral calculi were disintegrated by a 9Fr probe and the rigid nephroscope. Twelve patients with upper or middle ureteral calculi were treated using a 5Fr probe and the fiberscope. The stones in 9 patients with lower ureteral calculi were removed by a 5Fr probe and the rigid ureteroscope. Although small residual stones were observed in 15 patients (43%), all the stones were fragmented satisfactorily except in two patients. The complications due to EHL were observed in eight patients (23%). The most frequent complication was the ureteral injury which was observed in 6 patients. In 2 of these patients the stone migrated out from the ureter. However, all the cases of ureteral injury were healed by the conservative therapy such as by indwelling the stent catheter without ureteral stricture.

Effects of Triton WR 1339 and orotic acid on lipid metabolism in rats.

In order to investigate the effect of hepatic cholesterol flux on biliary bile acids, Triton WR 1339 and orotic acid were administered to rats, and the biliary cholesterol, phospholipids and bile acids were analyzed together with serum lipoproteins and hepatic lipids. Triton, which raised serum very low density lipoprotein and lipid levels and decreased serum high density lipoprotein liver lipid levels, increase the biliary cholic acid group/chenodeoxycholic acid group ratio (CA/CDCA) in the bile without affecting the total amount of bile acids and the other biliary lipids. Orotic acid, which decreased serum lipid and lipoprotein concentrations and increased liver lipid levels, increased the biliary excretion of cholesterol and phospholipids, but produced no significant change in the total amount of bile acids and in the CA/CDCA ratio in bile.

The beneficial effects of thoracic duct drainage in HLA-1 haplotype identical kidney transplantation.

The beneficial effects of pre-treatment thoracic duct drainage on graft survival in living related kidney transplantation are presented. Since July 1980 lymphocyte depletion through thoracic duct drainage has been used as pre-treatment therapy in 39 HLA-1 haplotype identical living related kidney transplant patients. Thoracic duct drainage was maintained for 29 to 49 days (mean 36 days) before transplantation and 52 to 215 times 10(9) cells (mean 130 times 10(9) cells) were removed. Postoperative immunosuppression consisted of azathioprine and steroids. Actuarial graft survival was 100 per cent at 3 months, 97 per cent at 6 months through 2 years, 92 per cent at 3 years and 57 per cent at 4 years after transplantation. Patient survival was 100 per cent at 3 months, 97 per cent at 6 months through 3 years and 86 per cent at 4 years. Pre-treatment thoracic duct drainage maintained for more than 28 days could have a significant role on the improvement of the graft survival in HLA-1 haplotype identical kidney transplantation.

[A case report of patient with advanced stomach carcinoma of linitis plastica type responding to multi-immunotherapy and chemotherapy].

Multiple-drug (OK-432, PSK and SPG) immunotherapy and chemotherapy provided remission of symptoms for 36 months in a patient aged 21 years suffering scirrhous gastric carcinoma associated with carcinomatous peritonitis in which direct infiltration to the pancreas, retroperitoneum and the left colon was observed. A remarkable improvement with time was observed by endoscopic and roentgenographic observation, and a substantial improvement was also observed in the NK-cell ratios of lymphocyte subsets of the OKT series in relation to immunologic parameters. A tumor necrosis factor [TNF]-like substance was thought to have been induced by multiimmunotherapy in this case.

[Susceptibility of clinical bacterial isolates to aztreonam].

In vitro activities of 7 antimicrobial agents against organisms (474 strains) isolated from patients with various infections in Ehime University Hospital from May to July 1986 were investigated. Summarized results are as follows: 1. Aztreonam (AZT) showed potent activities against Escherichia coli, Citrobacter sp., Klebsiella pneumoniae, Serratia marcescens, Proteus sp., Pseudomonas aeruginosa and Haemophilus influenzae. 2. Antimicrobial activities of AZT were especially superior against Proteus sp. to the third generation cephem antibiotics. 3. Enterobacter sp. seemed more susceptible to AZT than to cephem antibiotics, but minimum inhibitory concentrations of AZT against may isolates of Enterobacter sp. were in wide ranges.

[Descent of right renal vein--a case report].

Renal descensus with the descent of right renal vein and ureteroureterostomy was carried out in a 61-year-old male patient. The patient had a 9 X 6 mm calculus in his right kidney and 2 cm long stricture in his right upper ureter that had been caused by the previous surgery for ureteral calculus. This operation, which was described by Gil-Vernet, provided excellent results without any complications.

[A case report of inverted papilloma of the posterior urethra].

Sixty-seven cases of inverted papilloma have been reported in many anatomical sites of urinary tract but only 9 cases involving the posterior urethra have been described in Japan. We report the 10th case of inverted papilloma of the posterior urethra in a 27-year-old male who complained of macroscopic hematuria. The lesion was diagnosed cystoscopically and treated by transurethral resection.

[Synchronous triple primary malignant neoplasms in a 42-year-old female].

Synchronous triple primary malignant neoplasms, namely, retroperitoneal myxoid liposarcoma, sigmoid colon carcinoma and uterocervical carcinoma in situ in a 42-year-old female is reported. The retroperitoneal sarcoma and colonic carcinoma were resected simultaneously, while a hysterectomy was performed five months later. No genetic influence could be elicited in the present case. The synchronous triple primary, malignant neoplasms in this case should be considered as having arisen by mere chance. Other cases in which triple or more primary malignancies were resected are briefly reviewed. In addition, cases of triple or more primary malignant tumors with include at least one sarcoma are also reviewed.
