    ABSTRACT: We discuss the effectiveness of in situ extracorporeal shock wave lithotripsy (ESWL) for the ureteral stones causing acute renal failure in 5 patients (4 men and 1 woman, mean age 56.2 years). Three of them had a sole functioning kidney, one had a solitary kidney and the other had bilateral ureteral stones. The obstructing stones were located in the upper ureter in one, lower ureter in 2, upper and lower ureter in one and bilateral upper ureter in one with the average length of the stones being 9.2 mm. We used the EDAP LT-01 device for these stones. The obstructing stones were successfully disintegrated by ESWL alone in three cases, but could not be disintegrated in the other 2 cases in which the obstruction had occurred gradually or there were multiple stones. In the latter 2 cases, we performed ESWL again with percutaneous nephrostomy or hemodialysis. We thus believe that ESWL is a safe and effective procedure and is the first choice of emergency treatment for some ureteral stones causing acute renal failure. However, the subject is limited to acute cases, and the stone must be easily detected, single with its size being less than 12 mm and composed of calcium.

    ABSTRACT: We treated 3 cases of ureteral stones which caused spontaneous peripelvic extravasation by extracorporeal shock wave lithotripsy (ESWL). None had histories of trauma or operation. The obstructing stones measured 6 x 5, 6 x 5 and 4 x 3 mm respectively, and each was located in a left upper, right upper and right lower ureter. The drip infusion pyelography (DIP) and computerized tomography (CT) revealed a mildly dilated collecting system and ureter of affected site and extravasation of contrast material around the kidneys. These stones were successfully crushed and discharged by ESWL performed with an EDAP LT-01 device. One week after the last ESWL, the DIP showed favorable urograms and extinctions of extravasation. As ESWL could achieve a release of calculous obstruction easily with a safe and non-invasive procedure, we confirmed it to be an effective treatment for similar types of ureteral stones causing peripelvic extravasation.

    ABSTRACT: We performed extracorporeal shock wave lithotripsy (ESWL) to 5 solitary kidney patients with upper urinary tract stones (4 kidneys and 1 lower ureter) using the EDAP lithotripter LT-01 and achieved 4 complete and 1 well results. The size of stones ranged from 8 mm to staghorn and trials were 1 to 10 units. We could accomplish perfect crushing and abortion of stones in the 4 renal stone patients without any adjuvant systems as ureteral stent but nephrostomy was needed in the 1 lower ureteral stone patient developed anuria. The values of blood pressure, hematology, blood chemical constituents and urine excretion enzymes at a month after the last ESWL were not so changed compared with those of preoperation and also excretory urogram showed favorable findings. In this series decreased renal functions by ESWL were not observed. We confirmed ESWL was an effective and a safe method even in the cases of solitary kidney patients and monotherapy without any adjuvants was possible.

    ABSTRACT: We report a case of left renal artery aneurysm with ring-like calcification in a 57-year-old man. The selective renal arteriography showed a 30 x 28 mm saccular type aneurysm arising from the periphery of the bifurcation of posterior segment artery. There were no clinical symptoms, such as hypertension and loin pain, but we performed aneurysmectomy for fear of rupture. Histopathological findings showed atherosclerotic changes with marked calcification of wall lacking natural collagen fibers. Renal artery aneurysm with calcification seldom ruptures because of its generally hard wall. However, as cases of rupture through weakness of calcification have been reported, we recommend positive surgical treatment.

    ABSTRACT: A 37-year-old man visited our hospital with the chief complaint of a painless mass in subcutaneous tissue of the pubis. We extirpated the localized cyst 2.5 x 4 cm in size. Histological diagnosis was cystic lymphangioma without malignant findings. We reviewed the literature on lymphangioma, a rare disease seldom seen in urological fields.

    ABSTRACT: We report a rare case of anomalous inferior vena cava (IVC) in a 46-year-old woman hospitalized for the examination of right hypofunctional kidney. She had no history of trauma or pyelonephritis and there were no abnormalities in laboratory findings except serum creatinine value. Excretory urography showed no excretion of contrast medium from right kidney and retrograde pyelography revealed moderate hydronephrosis of right kidney but the obstruction of the ureter was not recognized. Abdominal computed tomographic scan showed a total trace of IVC and inferior venacavography demonstrated complete obstruction of the IVC from its origin with collateralization of upper lumber veins and vertebral veins. Surgical exploration was performed and demonstrated that IVC was a trace from the postrenal segment to hepatic segment. Two right renal veins were draining into the upper lumber vein and the right ureter was compressed slightly by lower renal vein, dilated ovarian vein and fibrotic connective tissue.

    ABSTRACT: A 69-year-old man initially came to our hospital with the chief complaint of dysuria and hematuria. On rectal examination, the prostate gland was found to be grossly enlarged and rock hard in consistency. Abnormal laboratory data included: lactate dehydrogenase, alkaline phosphatase, acid phosphatase and prostatic acid phosphatase. Chest X-ray revealed multiple nodular lesions in both lung fields. Pathologic findings of the prostate needle biopsy revealed moderately well differentiated adenocarcinoma. Early combined hormonal and chemotherapy (adriamycin, TGF, methotrexate, bleomycin) was performed. After two courses of this regimen, the pulmonary lesions vanished completely. In addition, partial disappearance of osteoblastic lesions on bone scans was recognized.

    ABSTRACT: A 34-year-old man visited our clinic because of right testicular swelling, pain and scrotal erythema. At first he was diagnosed as having acute epididymitis and received medical treatment. Nevertheless, his course was poor and was hospitalized after 1 month. Incision to the scrotum was performed and about 30 ml of dark yellow pus was drained. Culture of the pus yielded E. coli which was susceptible to all kinds of antibiotics. The local symptoms subsided, but the right testicular pain still persisted. Right epididymectomy was attempted on the 22nd hospital day. At the operation an abscess formation in testis was found but no marked changes in the epididymis were found. Right orchiectomy was performed. Histology of testis showed extensive necrosis and severe infiltration of many inflammatory cells. We report this rare case of pyogenic orchitis with abscess formation.

    ABSTRACT: The acute changes of proximal tubule function and its pathological condition were investigated by measuring (gamma-GTP) activities in the urine and renal tissue using warm ischemic kidneys of adult dogs (n = 34). Eight kidneys were kept in a warm ischemic condition throughout the experimental period and the tissue was extirpated from the kidney at every hour, and 31 kidneys were released from the 30 min ischemic condition. The urine and the blood (peripheral and renal artery and vein) were collected from these kidneys at every hour up to 5 hr. The kidneys observed for urine outflow (n = 24) were divided into three groups with time; 7 kidneys (1 hr), 5 kidneys (3 hr), and 12 kidneys (5 hr), and they were extracted. The gamma-GTP activity of the urine showed the maximum value of 851 +/- 102 mIU/ml at 30 min and decreased to 217 +/- 56 mIU/ml, which declined to be close to the starting value of 133 +/- 26 mIU/ml, at 5 hr after the warm ischemic condition was released. The gamma-GTP activities of the cortex were 325 +/- 62 mIU/mg.p (1 hr), 527 +/- 37 mIU/mg.p (3 hr), and 266 +/- 44 mIU/mg.p (5 hr). However, no increase in gamma-GTP activity was observed either in the renal vein blood, or in the cortex obtained from the 8 kidneys kept in the warm ischemic condition. A histopathological examination showed the progressive changes in some parts of the proximal tubules after release from the ischemic condition.(ABSTRACT TRUNCATED AT 250 WORDS)

    ABSTRACT: A 58-year-old man visited the urological clinic in Prefectural Tohkamachi Hospital with complaint of swelling of bilateral scrotal contents. He had no history of fever, pain or difficulty of urination. Physical examination revealed a giant mass of adult-head size in right scrotum and left inguinal hernia of fist growth. Surgical extirpation of the right scrotal mass and left inguinal herniorrhaphy was performed and the mass was diagnosed as obsolete hydrocele testis and weighed 1,600 g. The excised hydrocele sac showed marked thickening and dark brown pus amounted to about 1,400 ml, which was negative in bacterial culture. Histological examination revealed partial deposits of cholesterol and calcification in tunica vaginalis with extremely atrophic testis and destructive spermatogenesis. The findings suggested the existence of long-term infection in hydrocele testis. The etiology and pathogenesis of this disease is discussed.

    ABSTRACT: A 37-year-old male visited our hospital with the chief complaint of a mass about the size of a hens egg in the right scrotum. Before hospitalization, he had noticed the abnormal intrascrotal mass. The mass gradually enlarged with pain, so he was admitted on May 23, 1982. Under the diagnosis of intrascrotal tumor, the mass was removed. It was a cyst with enriched geratinoid contents enclosed with thick granulation tissue and adhered to the tunica vaginalis externally. Pathological findings revealed it to be an intrascrotal pseudocyst. Discussion is made in relation to the histological genesis of this lesion.
