Renal artery aneurysm causing hydronephrosis.

A 42-year-old man presented with left hydronephrosis incidentally discovered on abdominal echogram during a routine health examination. Color Doppler ultrasonography, intravenous pyelography and angiography revealed a non-calcified renal artery aneurysm of 30 mm in size compressing the pyeroureteral junction and causing hydronephrosis. Three-dimensional computed tomography (3-D CT) using spiral CT clearly displayed the aneurysm located at the first bifurcation of the left renal artery and involving the anterior segmental artery. Decompression was successfully obtained via in situ revascularization of the renal artery after aneurysmectomy. A literature search revealed 12 cases of renal artery aneurysm causing hydronephrosis reported in Japan, although only three cases were documented in other countries, and these reports are reviewed. Use of 3-D CT for evaluation of renal artery aneurysm is advocated.

[Renocolic fistula: a case report].

A 78-year-old woman had disregarded pneumaturia since April 1998. In March 1999, computed tomography and barium enema were done to examine anemia and positive fecal occult blood, revealing a left renocolic fistula and bilateral renal stones. Intravenous pyelography revealed a left staghorn calculus, non-functioning kidney, and right partial staghorn calculus. Urinalysis showed pyuria and the culture grew Proteus vulgaris and Klebsiella oxytoca. Smear and culture of the urine were negative for acid-fast bacilli. In consideration of the patient's age and conservation of right renal function, right pyelolithotomy was performed first. Three weeks later, left nephrectomy and partial colectomy were done. The postoperative course was uneventful. A renocolic fistula is relatively rare and to our knowledge there have been 37 cases reported in Japan, including our case. Surgery is the main therapy and was performed in 31 patients. Among them, surgery was not curative in 1 and 5 died of postoperative complications. Thus, surgery is not safe in all cases. However, despite her age and bilateral renal dysfunction, our patient was successfully operated on.

[A clinical study on renal pelvic and ureteral tumor associated with bladder tumor with special reference to risk factors of subsequently recurrent bladder tumor].

PURPOSE: The purpose of this report is to analyze the clinical feature of renal pelvic and/or ureteral tumor (RUT) associated with bladder tumor (BT) with special reference to risk factors of subsequently recurrent BT. METHODS: Of the 49 patients with RUT who underwent surgery and were diagnosed pathologically as transitional cell carcinoma at the Department of Urology, Osaka National Hospital from April 1986 to October 1996, 20 patients (40.8%) had associated BTs. These patients were categorized to the following 4 groups, Group 1: 5 patients with BT preceding RUT, Group 2: 5 patients with concomitant BT, Group 3: 10 patients with subsequent BT following RUT operation and Group 4: 29 patients without any associated BT. The clinical course of these 4 groups were studied and compared with each other retrospectively. RESULTS: In group 1, the first BTs preceded RUTs by 19 to 81 months (mean 54.6 months). And during this relatively long period, the preceding BTs were treated by TUR for each recurrence, 1 to 9 times (mean 5.2 times). Two of 5 were bilateral RUT cases, which were observed only in this group. In group 2, the prognosis were relatively poor (5-year survival rate: 0%), because all RUTs of this group were high stage. And also the concomitant BTs were showing invasive feature during the observation period, despite they were superficial at first. Thus 3 of 5 underwent radical cystectomy. On the other hand, in group 3, the subsequent BTs, which developed at 2 to 26 month (mean 13.4 month) after RUT operation, were all superficial and resectable by TUR. The 5-year disease specific survival rate was 50% in group 1, 0% in group 2, 63.5% in group 3, 64.9% in group 4. Group 2 had the most poor prognosis. However there was no significant difference in prognosis among the 4 groups. Incidence of preoperative urine positive cytology was significantly higher in group 3, than in group 4 (87.5% vs. 44.8%). CONCLUSIONS: These results indicated that the RUTs with associated BTs have distinct clinical features depending on the sequence of association with the BTs. Especially the RUTs with concomitant BTs should be watched carefully as a high risk group with poor prognosis and possible development of invasive BTs. Positive urine cytology prior to RUT operation may reflect biological activity of tumor cell for dissemination in the lower urinary tract and we suggested preoperative urine cytology was possible predictor of subsequently recurrent BTs after RUT operation in this study.

[A case of crossed fused kidney with simple ureterocele].

A 32-year-old man consulted Osaka National hospital with chief complaints of dysuria and macrohematuria. DIP and CT revealed that the right kidney deviated to the lower pole of the left kidney and they fused together. The right ureter crossed over the supine. The calcified shadow existed in the lower end of the left ureter with cobra head image. He had no external anomalies. Under diagnosing crossed fused kidney (inverted L shaped) complicated the left ureterocele with a stone, transurethral incision of ureterocele (TUI) was performed. We made transverse incision and extracted stone, 7 mm in size (calcium oxalate 96% and calcium phosphate 4%). Three months later after the operation, IVP, CG and VCG revealed the down-sized ureterocele and no VUR. Crossed renal ectopia complicated many anomalies about 50%. Among them anomalies of the urinary tract was most frequent about 30%. But crossed renal ectopia with ureterocele wasn't reported so far in Japanese literature.

[A clinical study on renal pelvic and ureteral cancer--with special reference to prognostic factors and adjuvant chemotherapy].

PURPOSE: This report focuses on the prognostic factors of the renal pelvic and ureteral cancer and on the treatment for advanced and/or recurrent cases. METHODS: We reviewed the forty-nine patients with transitional cell carcinoma of the renal pelvis and/or ureter who underwent surgery at the Department of Urology, Osaka National Hospital from April, 1986 to October, 1996. Univariate and multivariate analysis was done on the pathological features from these patients. RESULTS: The patients consisted of 34 males and 15 females and the mean age was 64.9, ranging from 27 to 83. Overall the 1, 3 and 5-year disease specific survival rates were 93.5%, 70.2% and 61.3% respectively by the Kaplan-Meier's method. The prognostic significance of the 6 pathological factors (pT, Grade, INF, pL, pV and pR) were evaluated statistically in terms of generalized Wilcoxon test and/or Cox-Mantel test. All the 6 factors effected on survival rates significantly. However, the grade, INF, pL, pV and pR factors were closely related to the pT factor. Moreover the pT factor was confirmed to be the most important and independent factor according to a multivariate analysis by the Cox's proportional hazard model. And the grade 3 factor with pT2 or higher stage was a high risk factor in recurrences significantly, in spite of curatively operated cases. Thirteen patients with high stage, metastasis or recurrences were treated after operation with the M-VAC or modified M-VAC regimen as preventive, adjuvant and/or salvage chemotherapy. The overall response rate was 72.7% in eleven cases with evaluable lesions, while these regimens could not be expected to improve long-term survival rate. The response rate of combined chemoradiation therapy was 66.7% for six cases with the localized recurrent cancer. CONCLUSIONS: The pT factor was the independent predictor of disease-specific survival. Adjuvant chemotherapy for prevention of cancer recurrence should be considered in the case of pT2 or higher stage plus grade 3 factor, even if curatively operated cases. The M-VAC or modified M-VAC regimen was reconfirmed to be useful as first line chemotherapy of advanced renal pelvic and ureteral cancer. Combined chemoradiation therapy was useful for the localized cancer recurrences, especially as a second line therapy for relapsed cases after M-VAC chemotherapy in this series.

[Study on the duration of pyuria after transurethral resection of prostate].

A retrospective study was conducted on the duration of pyuria after transurethral resection of the prostate (TURP) and the factors affecting the duration in 273 patients, who were diagnosed as having benign prostatic hyperplasia (BPH) with postoperative resolution of pyuria among those who underwent TURP over the last ten years at our clinic. In the 273 patients, the mean (+/- SD) weight of the resected prostate was 13.2 +/- 10.2 g (range : 1-52 g), the mean operating time was 74.3 +/- 29.8 min (25-215 min), the duration of pyuria was 110.6 +/- 38.3 days (23-273 days), and the resected weight to operating time ratio was 0.172 +/- 0.093 g/min (0.018-0.500 g/min). There was a significant correlation between the duration of pyuria and the patient's age, resected weight, operating time, or resected weight/operating time ratio, resected weight being the most important factor. The surgeon, the postoperative antibiotics used, and the preoperative existence of pyuria did not have any significant effect on the duration of postoperative pyuria. Investigation after stratification by the resected weight in 10 g increments suggested that a shorter operating time was important to reduce the duration of postoperative pyuria, particularly in BPH patients with a resected weight of 20-29 g.

[Proliferating character of inverted papilloma of the urinary bladder].

BACKGROUND: Inverted papilloma (IP) of the urinary bladder is generally considered to be a benign lesion by histological examination. In recent years, however, there have been several cases of IP simultaneously accompanied with transitional cell carcinoma (TCC), elsewhere in the bladder or combined as a single urothelial lesion. So we investigated proliferating character of IP by DNA ploidy analysis and immunohistostaining with proliferating cell nuclear antigen (PCNA). METHODS: Six cases of IP of the urinary bladder were analyzed and 12 cases of TCC of G1 and G3 grade were included in this study as a control. As DNA ploidy analysis, all specimens were feulgen stained using CAS DNA staining kit and examined by image cytometry (CAS 200R system). For the PCNA immunohistochemistry, all specimens were stained with anti-PCNA monoclonal antibody (Novocastra Lab.: PC10) according to ABC (avidin-biotin-complex) standard method. We determined that the DNA Index of the case under 1.20 was diploid and the others was aneuploid. PCNA staining were determined by only one pathologist as follows: negative (-) and positive (+), (2+) and (3+). RESULTS: As DNA ploidy, 5 of 6 cases of TCC G3 group as a control were aneuploid. But in spite of all cases of TCC G1 group were diploid, among IP cases, only 1 out of 6 was aneuploid. As PCNA staining, 2 of 6 in TCC G1 group and 5 of 6 in G3 group were positive. And it was noted examination was positive. CONCLUSION: There have been no recurrence since transurethral resection in all IP in the study including the case recognized as aneuploid and positive for PCNA staining. But the present results suggest that among IPs, considered generally as a benign tumor, the case which has high proliferating character exists.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1994). III. Secular changes in susceptibility].

Susceptibilities of Enterococcus faecalis, Staphylococcus aureus, Citrobacter spp., Enterobacter spp., Escherichia coli, Klebsiella spp., Proteus mirabilis, Pseudomonas aeruginosa and Serratia spp. isolated from patients with urinary tract infections (UTIs) in 10 hospitals during June 1994 to May 1995 to various antimicrobial agents were compared with those in the same period of previous years according to a classification, uncomplicated UTIs, complicated UTIs without indwelling catheter, and complicated UTIs with indwelling catheter. No remarkable changes were found in susceptibilities of Citrobacter spp., Enterobacter spp. and Serratia spp. The susceptibilities of E. faecalis to amikacin and quinolones were better than those in 1993. As for S. aureus, susceptible strains to all drugs increased in uncomplicated UTIs. Against E. coli in 1993, the antimicrobial activities of piperacillin, cefotiam and aminoglycosides have decreased, however, in 1994, these activities have turned to the better state. As for Klebsiella spp. susceptible strains to ABPC decreased. The susceptibilities of P. mirabilis to all drugs except minocycline were good. Against P. aeruginosa in 1993, the activities of aminoglycosides have decreased, but, in 1994, these activities have turned to the better state. These data should be considered in clinical treatment of various urinary tract infections.

[Clinical studies of inverted papilloma of the bladder].

Clinical studies were conducted on 9 cases of inverted papilloma of the urinary bladder which were transurethrally resected between August, 1987 and July, 1995 at our hospital, in males between 29 and 81 years of age (mean:58.3). Six of the 9 inverted papillomas were localized at the bladder neck and 3 in the trigone. Cystoscopic examinations revealed that inverted papillomas were divided into two types, one with a thick and short stalk with a smooth surface and the other with a thin and long stalk with/without a partial papillary surface. The majority of the former was located in the trigone and all of the latter cases in the bladder neck, suggesting that the two types occurred at different sites. Pathological examination by Hematoxylin-Eosin staining demonstrated that 5 of the 9 cases were of the trabecular type and 4 were of the grandlar type. Immunohistochemically, none of the tumors were stained with the antiprostatic-specific-antigen antibody revealed. Follow-up periods after the operation were from 12 to 48 months(mean:26.6 months) and no recurrence was observed.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1994). I. Susceptibility distribution].

The frequencies of isolation and susceptibilities to antimicrobial agents were investigated on 567 bacterial strains isolated from patients with urinary tract infections in 10 hospitals during the period of June 1994 to May 1995. Of the above total bacterial isolates, Gram-positive bacteria accounted for 26.8% and a majority of them were Enterococcus faecalis. Gram-negative bacteria accounted for 73.2% and most of them were Escherichia coli. 1. Enterococcus faecalis.

Cephems were active with the MIC90s of 2 approximately 16 micrograms/ml, but penicillins and quinolones were not so active with the MIC90s and 64 approximately 128 micrograms/ml. 4. Citrobacter freundii. Gentamicin (GM) showed the highest activities against C. freundii isolated from patients with urinary tract infections. Its MIC90 was 1 microgram/ml. IPM was also active with the MIC90 of 2 micrograms/ml. Cefpirome (CPR) and cefozopran (CZOP) were also active with the MIC90s of 4 micrograms/ml and 8 micrograms/ml. The others were not so active with the MIC90s of 32 micrograms/ml or above. 5. Enterobacter cloacae. IPM showed the highest activities against E. cloacae. Its MIC90 was 0.5 microgram/ml. GM and amikacin (AMK), ciprofloxacin (CPFX) and tosulfloxacin (TFLX) were also active with the MIC90s of 4 micrograms/ml. Penicillins and cephems except latamoxef (LMOX), cefmenoxime (CMX), CPR and CZOP showed lower activities with the MIC90s of 256 micrograms/ml or above. 6. Escherichia coli. Most of antimicrobial agents were active against E. coli. CPR, CZOP, IPM, carumonam (CRMN), CPFX and TFLX showed the highest activities against E. coli. The MIC90s of them were 0.125 microgram/ml or below. Cefotiam (CTM), flomoxef (FMOX) CMX, ceftazidime (CAZ), and LMOX were also active with the MIC90s of 0.25 microgram/ml. Penicillins were not so active with the MIC90s of 128 micrograms/ml or above. 7. Klebsiella pneumoniae. CRMN showed the highest activities against K. pneumoniae. Its MIC90 was < or = 0.125 microgram/ml. CZOP was also active with the MIC90 of 0.25 microgram/ml. Penicillins were not so active with the MIC90s of 128 micrograms/ml or above. 8. Proteus mirabilis. P. mirabilis was susceptible to a majority of drugs. CMX, CAZ, LMOX, CRP, cefpodoxime (CPDX), CRMN, CPFX and TFLX showed the highest activities against P. mirabilis isolated from patients with urinary tract infections. The MIC90s of them were 0.125 microgram/ml or below. MINO was not so active with the MIC90 of 128 micrograms/ml. 9. Pseudomonas aeruginosa. Most of the agents were not so active against P. aeruginosa. IPM showed MIC90 of 8 micrograms/ml. The others were not so active with the MIC90s of 16 micrograms/ml or above. CPFX showed MIC50 of 0.5 microgram/ml.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1994). II. Background of patients].

Clinical background was investigated on 628 bacterial strains isolated from patients with urinary tract infections (UTIs) in 10 hospitals during period from June, 1994 to May, 1995. 1. Distributions of sex, age and urinary tract infections Among over sixties males, the majority was taken by complicated urinary tract infections. Among females, the uncomplicated urinary tract infections was most frequent without a relation of age. As for over 40 females, the increase of complicated UTI was admitted. 2. Distribution of sex, age and pathogens isolated from UTIs In uncomplicated UTIs, Escherichia coli was most frequently isolated without a relation of age, and next Enterococcus faecalis and CNS. In complicated UTIs without indwelling catheter, E. coli, Pseudomonas aeruginosa and E. faecalis were isolated the most frequent. In complicated UTIs with indwelling catheter, P. aeruginosa was most frequently isolated, and next E. faecalis and Staphylococcus aureus. 3. Administration of antimicrobial agents and pathogens isolated from UTIs In uncomplicated UTIs, pathogens, after administration of antibiotics, isolated from patients have obviously decreased from 216 to 32 isolates. And also, pathogens of complicated UTIs without indwelling catheter, have decreased from 127 to 50 isolates. However, in complicated UTIs with indwelling catheter, pathogens after or before administration of antibiotics, were not revealed an obvious change. 4. Pathogens and UTIs with or without factor and operation In uncomplicated UTIs with or without factor and operation, E. coli was mainly detected. In complicated UTIs without indwelling catheter and with factor and operation E. faecalis was mainly detected, and next E. coli, S. aureus and P. aeruginosa. Without factor and operation, E. coli was mainly detected. In complicated UTIs with indwelling catheter and with factor and operation, P. aeruginosa, E. faecalis and S. aureus were mainly detected at 23.5%, 15.0%, 15.0%, respectively. Without factor and operation, Proteus spp. 22%, and next E. faecalis and P. aeruginosa 10% and 12%, were detected, respectively. The distribution of pathogens, in the case of Proteus spp. and P. aeruginosa has been obviously varied by the influence of factor and operation.

Erythropoietin-producing adrenocortical carcinoma.

A 62-year-old Japanese male with an erythropoietin-producing adrenocortical carcinoma is presented. The elevated erythropoietin level and erythrocytosis returned to normal after surgical removal of a huge left adrenal tumor weighing 1,580 g. A histopathological diagnosis of adrenocortical carcinoma was made. Despite adjuvant combined chemotherapy, the patient died of lung and liver metastases 3.5 months after operation. Although the possibility that the elevated plasma erythropoietin level and erythrocytosis resulted from local kidney hypoxia, caused by pressure from the huge adrenal tumor, cannot be completely neglected, the positive cytoplasmatic evidence of immunoreactive erythropoietin in the carcinoma cells and the detection of a high erythropoietin level in the tumor extract on radioimmunoassay confirmed that this is a very rare case of erythropoietin-producing adrenocortical carcinoma.

Renal leiomyoma associated with tuberous sclerosis.

The renal lesions characteristic of tuberous sclerosis are angiomyolipoma and cysts, with the former considered to be more common. Other renal tumors are rarely associated with tuberous sclerosis. Here we present a tuberous sclerosis patient with a renal leiomyoma which was detected incidentally during the investigation of fever of unknown origin.

[Clinical studies of 15 cases of renal angiomyolipoma].

Fifteen cases of renal angiomyolipoma seen between May, 1988 and October, 1994 in our hospital are presented. Surgical treatment was performed in 6 cases, 1 of which was falsely diagnosed as liposarcoma by frozen specimen during the operation. Nine cases were only followed-up by ultrasonography and/or computed tomography. In 2 cases, in which enucleation was performed after a follow-up period of more than one year, tumors were inclined to grow rapidly. In 5 cases, which were not operated and followed-up for more than one year, tumors were inclined to grow very slowly.

[Giant schwannoma in the pelvic cavity presenting as renal failure: a case report].

A case of giant schwannoma in the pelvic cavity detected with renal failure is reported. A 50-year-old man was referred to another clinic with chief complaints of general fatigue and edema of the face and dorsa of the feet. On March the 4th 1994, he was hospitalized in the clinic because of renal failure. Bilateral hydronephrosis and a giant pelvic tumor were found by computed tomography (CT) and ultrasonography. Because bilateral percutaneous nephrostomies failed to recover his renal function, he was referred to our clinic for the purpose of hemodialysis and the further examination of the tumor on March 16, 1994. The pelvic angiography showed that the tumor was fed by the vessel from the left internal iliac artery. After the chemo-embolization from the feeding artery, tumor resection was performed on May 9, 1994. The tumor was 16x13x10 cm in size, and 1,110 g in weight. The histological findings of the tumor revealed the mixed type schwannoma of Antoni A and B. Six months after the operation, he has had no tumor recurrence. This is a rare case of pelvic schwannoma which was detected with renal failure. We reviewed and discussed 56 cases of schwannoma in the pelvic cavity, including our case, in the Japanese literature.

[Intrascrotal fibrous pseudotumor accompanied by pelvic kidney with ectopic ureteral opening: a case report].

A case of intrascrotal fibrous pseudotumor accompanied by pelvic kidney with ectopic ureteral opening is reported. The patient was a 65-year-old man with the complaint of swelling of the right scrotal contents. Ultrasonography showed a heterogeneous mass with acoustic shadow from the right epididymis to right spermatic cord. Intravenous pyelography revealed a non-visualizing right kidney. Endoscopic examination was performed because of the right non-functioning kidney and right epididymectomy was performed. Endoscopic findings showed that the ureteral opening existed at 6 degrees of the bladder neck. Retrograde pyelography demonstrated the right kidney in the pelvic cavity. The tumor was stony hard and 30 x 50 mm in size. Pathological diagnosis of the tumor was a fibrous pseudotumor. We reviewed and discussed 22 cases of fibrous pseudotumor, including our case, in the Japanese literature.

[Recurrence of transitional cell carcinoma in bilateral upper urinary tracts and ileal conduit with invasion in the abdominal wall around nephrostomy after total cystectomy: a case report].

A case of recurrence of transitional cell carcinoma in bilateral upper urinary tracts and ileal conduit with invasion in the abdominal wall around nephrostomy after total cystectomy is presented. A 33-year-old man with right nephrostomy, after total cystectomy, construction of ileal conduit, bilateral partial ureterectomy and left nephrectomy for transitional cell carcinoma at another hospital was referred to our hospital because of further recurrence in the right renal pelvis and ileal conduit. He had had left nephrostomy before the left nephrectomy was performed. Right nephrectomy and total extirpation of ileal conduit were performed and hemodialysis was started from the day after the operation. However, several weeks later, transitional cell carcinoma was detected pathologically in the left abdominal wall around the left nephrostomy which had been inserted. The renal pelvis was inferred to have leaked urine around the nephrostomy and invasion arose in this region. After radiation therapy he was discharged but he died from recurrence of carcinoma 9 months after the operation. After total cystectomy, examinations by percutaneous puncture of the renal pelvis are very effective for evidence of recurrence in the upper urinary tract. However, we emphasize that the percutaneous technique carries the risk of tumor invasion through the percutaneous urinary tract.

[Clinical studies of chemotherapy for patients with a solitary kidney after nephroureterectomy for advanced upper urothelial transitional cell carcinoma].

Between June, 1987 and December, 1993, ten patients with solitary kidney after total nephroureterectomy for advanced upper urothelial transitional cell carcinoma were treated with chemotherapy (M-VAC or modified M-VAC). This series comprised 6 males and 4 females between 27 and 81 years of age (mean age: 58.5 years). The site of primary lesions was the renal pelvis in one case, ureter in 5 and renal pelvis and ureter in 4. Histologically, these extripated tumors were all identified as transitional cell carcinoma, the stage being pT3 and pT4 in 9 and grade being G3 in 8 of the 10 patients. Among the 13 cases including the 3 cases of recurrence after first line chemotherapy, 7 had lesions suitable for the evaluation. Two of the 7 cases achieved complete response and four achieved partial response, resulting in an 86% response rate. Of the 10 patients, 4 died of metastasis of carcinoma and the others are still alive. The average period after operation among 10 patients was 25 months. Side effects related to this chemotherapy were as follows: general fatigue, nausea or vomiting and alopecia 100%, leucocytepenia (< or = 1,000/mm3) 23%, anemia (RBC < or = 250 x 10(4)/mm3) 62%, thrombocytopenia (< or = 5 x 10(4)/mm3) 46%. However, nephrotoxicity in spite of solitary kidney was not noticed in any patients. From our experience, we suggest that M-VAC or modified M-VAC chemotherapy are safe against patients with a solitary kidney after nephroureterectomy for advanced transitional cell carcinoma of the upper urinary tract.

[A case report of condyloma acuminatum in female urethra].

A case of condyloma acuminatum in female urethra is reported. A 53-year-old woman was referred to our clinic because of urethral bleeding. A tumor was noted around the external urethral meatus and the size of the tumor was 20 mm in diameter. Excision was performed on the tumor including the external urethral meatus. Pathological examination revealed condyloma acuminatum. Condyloma acuminatum in female urethra is very rare. We reviewed and discussed 6 cases of condyloma acuminatum in female urethra, including our case, in the Japanese literature.
