[A case of primary psoas abscess with paravesical extension].

We report a case of primary psoas abscess with paravesical extension. A 16-year-old man who had suffered from remittent fever for two months was admitted to our clinic. He had no urological symptoms or walking disturbances, but ultrasonography showed a well-defined echoic mass at the right paravesical space. Computed tomography confirmed this finding, and right psoas muscle appeared to be enlarged with irregular low density areas. Percutaneous drainage for right paravesical abscess was performed, and 15 ml of pus was obtained. The bacterial and fungal culture of the specimen resulted in no growth of any organisms. Six days after percutaneous drainage, he received en bloc resection of right paravesical abscess with segmental resection of bladder wall and peritoneum adherent to it. Furthermore, the affected region of the right psoas muscle was salvaged as highly upward as possible. Surgical specimen disclosed, pathologically, a non-specific granuloma with stellate necrosis. This finding suggested a feature of cat-scratch disease, tularemia, lymphogranuloma venereum and Yersinia infection. We reviewed the related literature on diagnostic images such as CT, ultrasonography and 67Ga scintigraphy. Moreover, bacterial causes and therapy of primary psoas abscess are discussed.

[Inverted papilloma of the urinary bladder].

Five cases of inverted papilloma in the bladder are reported. All cases were males complaining of dysuria or hematuria. Total cystectomy with construction of ileal conduit was carried out in the first case, and transurethral resection in the other cases. Every surgical specimen was histologically diagnosed as inverted papilloma. The inverted papilloma is a distinct lesion characterized by its rarity compared to frequency of the other vesical papillomas. The prognosis is generally benign, but the possibility of recurrence and malignant transformation indicates the necessity of a close periodical follow-up.

[Chemolysis of cystine calculi incarcerated in the ureter by the alkaline organic amine, tromethamine-E].

We dissolved the cystine calculi incarcerated in the ureter by irrigation with tromethamine-E via percutaneous nephrostomy. Case 1: A 25-year-old man with a past history of cystinuria and staghorn calculi in the right kidney, suffered from obstructive renal failure caused by the incarceration of a stone (18 x 15 mm) in the left middle ureter. After recovering promptly from renal failure by left percutaneous nephrostomy, he received continuous irrigation with tromethamine-E through an angiographic catheter percutaneously placed in the ureter. The ureteral calculus was reduced by 70% in size after the irrigation for 35 days, and then extracted percutaneously. Case 2: A 3-year-old child had multiple cystine calculi in the right renal pelvis and ureter. Although a calculus in the renal pelvis was extracted by the percutaneous ultrasound lithotripsy, two calculi incarcerated in the middle ureter were impossible to remove by a percutaneous approach. The irrigation with tromethamine-E was initiated through the catheter placed percutaneously in the right ureter. Both calculi completely dissolved 47 days later. The chemolysis by irrigation with tromethamine-E was greatly valuable in the treatment of cystine calculi. This dissolution could be an alternative to surgery especially in the treatment of ureteral cystine calculi, which might be difficult to be extracted by the percutaneous or transurethral approach.

[Ureteral endometriosis].

We present a case of ureteral endometriosis in a 48-year-old postmenopausal patient who was hospitalized complaining of right flank pain & microhematuria. She had no bladder irritability. She had a past history of simple hysterectomy and left oophorectomy because of adenomyomatosis. At that time, right ovary and other pelvic organs were normal. Physical examination revealed slight swelling of the liver without tenderness. Laboratory data at admission revealed severe liver dysfunction due to liver cirrhosis. Excretory urography demonstrated right hydronephroureterosis and severe stricture of the right lower ureter. Right ureteral catheterization demonstrated a high degree of stricture at the distal third. Cytology of right pelvic urine was negative. Right nephroureterectomy was done because long segment of right lower ureter adhered to the peritoneum tightly and we could not rule out ureteral cancer. Pathological diagnosis was extrinsic endometriosis of the right ureter. Ureteral endometriosis is rare and postmenopausal endometriosis is also rare. In our case hyperestrogenemia caused by liver cirrhosis might have played a role in the genesis and progression of endometriosis.

[Clinical observation of bacterial isolates from urine specimens of outpatients].

Changes of bacterial isolates from urine specimens of outpatients with urinary tract infections (UTI) from 1977 through 1984 were studied. Organisms which were isolated from patients with bacteriuria of over 10(3) bacteria per ml of urine regardless of grade of pyuria were studied. The incidence of UTI, especially that of acute cystitis was decreased during the recent 8 years. E. coli was the most predominant isolate in acute UTI with an isolation frequency of over 70% every year, followed by S. epidermidis nearly every year. Citrobacter spp., Klebsiella spp., P. mirabilis and S. aureus were also isolated steadily every year. Bacterial isolates in acute UTI were generally composed of these six species of bacteria. Although many kinds of bacteria were isolated in chronic UTI, E. coli was the most frequent species with an isolation frequency of 17-37%, followed by E. faecalis except in 1981 and 1982. The tendency of gram-negative rods to increase in acute and chronic UTI was observed except in 1981 and 1982. A slight decrease in sensitivity of E. coli and P. mirabilis against ampicillin (ABPC) and sulbenicillin (SBPC) was observed in acute UTI. In chronic UTI, the tendency of the sensitivity of E. coli against ABPC, SBPC and nalidixic acid to recover and the tendency of the sensitivity of P. aeruginosa against dibekacin to decrease were observed. E. faecalis was estimated to be sensitive to gentamicin, cefazolin, minocycline and fosfomycin. However, unlike those species mentioned above, many strains of E. faecalis showed a positive disc sensitivity to these drugs.

[Clinical study of serum squamous cell carcinoma-related antigen levels in penile cancer].

A squamous cell carcinoma-related antigen (SCC-Ag), which has been recognized as a tumor marker of cervical cancer of the uterine, was detected in the serum with a radioimmunoassay and its clinical usefulness in penile cancer was evaluated. Seven serum samples of penile cancer, one of Paget's disease and two of condyloma acuminatum were analyzed for the SCC-Ag level. The mean +/- standard deviation of serum SCC-Ag level and positive rate (greater than 2.0 ng/ml) were 1.6 +/- 1.75 ng/ml and 14%. Neither pathological staging nor cell grading of penile cancer showed any relation to the serum SCC-Ag level. When the tumor of the penis has been recognized and a cut-off value of 1.0 ng/ml used, the positive rate of penile cancer was 71.4% and false positive rate of other benign penile tumors was 0%. Serum SCC-Ag values were changed parallel in to the clinical course in three patients. These results suggest that the detection of the serum SCC-Ag value may be of use for detection of penile cancer and monitoring of these patients.

[A case of prostate cancer with multiple pulmonary metastases].

A 65-year-old man was hospitalized with bloody sputum. His chest X-ray showed multiple nodules in both lung fields. Transbronchial lung biopsy demonstrated a poorly differentiated adenocarcinoma, which suggested that respiratory abnormalities might be metastatic cancer. Because he had noticed pollakisuria and dysuria, urologic consultation was sought. The findings of digital examination, urethrography, and ultrasonotomography suggested that he had an advanced prostate cancer. In addition, tumor markers of prostatic acid phosphatase (PAP), acid phosphatase (ACP), and prostate antigen (PA) showed abnormal titers; 120 ng/dl, 166 IU/l, and 15.4 ng/ml, respectively. The prostate tissue obtained by transperineal biopsy revealed histopathologically adenocarcinoma and positive findings in immunohistochemical staining for PAP and PA as well as the specimens from the lung. Bilateral orchiectomy and medication of 250 mg of DESD daily as an antiandrogen therapy improved respiratory symptoms. One week after the operation, the multiple shadows on the chest X-ray diminished dramatically. Moreover, serum values of PAP and PA also decreased to the normal range. He is alive in a stable condition 6 months after the operation.

[Clinical studies on doxycycline in the treatment of nongonococcal urethritis by Chlamydia trachomatis].

Twenty-one nongonococcal urethritis patients by Chlamydia trachomatis infection were treated with doxycycline (DOXY, Vibramycin) 200 mg/day orally for 2 weeks. The age of these patients were ranged from 17 to 52. C. trachomatis was eradicated 8(89%) of 9 cases on 3rd day and never reisolated on 7th day after treatment. Ten (83%) of 12 patients on 7th day and any patients on 14th day were not suffered from symptoms after treatment. Urethral discharge was not seen macroscopically, 11 (92%) of 12 patients on 7th day and any patients on 14th day. According to the criteria for urethritis requiring at least 4 WBC per high power field in urethral smear and/or first voided urine, the overall clinical efficacy rate was 44% (4/9) on 3rd day, 83% (10/12) on 7th day and 100% (9/9) on 14th day. No side effects were recognized in any cases. In conclusion, DOXY was thought to be useful and safe drug in the treatment of nongonococcal urethritis by C. trachomatis.

[Primary papillary adenocarcinoma of renal pelvis: a case report and review of the literature].

A rare case of primary papillary adenocarcinoma of the renal pelvis is reported. A 75-year-old man was introduced to our institute because of chance hematuria. He had no history of urolithiasis or urinary tract infection. Excretory urography showed a space taking lesion at the lower position of left renal pelvis with low function. Because of advanced stage with paraaortic lymphnode invasion, simple nephrectomy followed by irradiation and systemic chemotherapy with 5-FU was done. He died of pneumonia and acute heart failure after subtotal gastrectomy for peptic ulcer four months after the nephrectomy. Excised specimen revealed papillary adenocarcinoma of the renal pelvis without mucin production. This case was the 51st case reported in the literature. A short review of the disease is also reported.

[A case of leiomyosarcoma of the urinary bladder].

A case of leiomyosarcoma of the urinary bladder in a 33-year-old female is reported. She was admitted with the complaint of gross hematuria. Cystoscopic examination showed a thumb-tip sized mass, located at the dome. CT showed a wide-based tumor at the dome (CT number was 60.2 H.U.). Segmental resection of bladder was performed, followed by radiation and chemotherapy (VCR, ACT-D, CPM and ADM). She is alive without evidence of disease 13 months after surgery. A case report and review of the literature are presented.

[Urine polyamine in patients with malignant urological diseases using a polyamine-test enzyme kit].

Using a polyamine-test enzyme kit, the urine polyamine concentration was determined in 74 patients with malignant urological disease (12 with renal cell cancer, 13 with pelvic-ureter cancer, 24 with bladder cancer and 25 with prostate cancer), 7 patients with BPH, 20 patients with benign urological disease and 20 normal subjects. The urine polyamine level was significantly elevated in all the patients with any malignant urological disease compared to normal subjects. It was also significantly high in the patients with BPH. Defining the mean +/- 3SD (= 50 mumole/g Cr.) of 20 normal subjects as an upper limit, slightly higher levels not exceeding 100 mumol/g Cr. were frequently observed in the patients with BPH or with benign urological disease. Setting the upper limit at 100 mumole/g Cr., the positive rate amounted to 33% (low stage 17%) in renal cell cancer, 23% (low stage 14%) in pelvic ureter cancer, 13% (low stage 0%) in bladder cancer and 4% (low stage 0%) in prostate cancer. The positive rate was low especially in low stage cases.
