    ABSTRACT: The data of sexually transmitted urethritis in males have been collected at 24 institutes in Kyoto Prefecture since October, 2002. The data collected from January to December in 2004 are summarized herein. A total of 1,275 patients were diagnosed with urethritis during this period. Microbiological examinations isolated Neisseria gonorrhoeae alone in 368 (29%), Chlamydia tracomatis alone in 336 (26%), both in 85 (7%), and others in 453 (36%). Male patients under 20 years old tended to have Chlamydial urethritis, alone or combined with gonococcal infection, and had a predominant infectious source, a non-commercial-sexual-worker female partner, suggesting a profound problem in sexual life of adolescents. The urologist preferred to use quinolones as the first therapeutic modality against male urethritis. However, drug resistance of N. gonorrhoeae, especially against quinolones, has rapidly progressed, which was also observed by a sensitivity examination test. Antibiotics should be used adequately against male urethrits according to the recent guidelines.

    ABSTRACT: A prospective randomized study was conducted to evaluate the efficacy of prophylactic intravesical instillation of pirarubicin (THP) prior to transurethral resection (TUR) of superficial bladder cancer. A total of 63 patients were randomized into two groups, the THP group and the control group. In the THP group, 30 mg of THP dissolved in 50 ml saline was administered 4 times intravesically for 4 consecutive days before TUR. In the control group, no instillation was performed before TUR. The patients were followed by cystoscopy and urinary cytology every 3 months. The non-recurrence rates in the THP group and control group were 54.1% versus 37.6% at 1 year and 40.4% versus 26.8% at 2 years, respectively (P = 0.086). Time to recurrence for tumors larger than 1 cm was significantly longer in the THP group (P = 0.0137). Time to recurrence for single and grade 1+2 tumors tended to be longer in the THP group (P = 0.09, P = 0.079). No significant adverse effects were observed in any patient. Our findings suggest that intravesical THP instillation prior to TUR would be effective for patients with single, low grade lesions larger than 1 cm of superficial bladder cancer.

    ABSTRACT: In order to assess the ability of our protocol for antibiotic prophylaxis to prevent perioperative infections in urologic surgery, 1,353 operations of open and laparoscopic urologic surgery conducted in 21 hospitals between September 2002 and August 2003 were subjected to analyses. We classified surgical procedures into four categories by invasiveness and contamination levels: Category A; clean less invasive surgery, Category B; clean invasive or clean-contaminated surgery, Category C; surgery with urinary tract diversion using the intestine. Prophylactic antibiotics were administrated intravenously according to our protocol, such as Category A; first or second generation cephems or penicillins on the operative day only, Category B; first and second generation cephems or penicillins for 3 days, and Category C; first, second or third generation cephems or penicillins for 4 days. The wound conditions and general conditions were evaluated in terms of the surgical site infection (SSI) as well as remote infection (RI) up to postoperative day (POD) 30. The SSI rate highest (23.3%) for surgery with intestinal urinary diversion, followed by 10.0% for surgery for lower urinary tract, 8.9% for nephroureterctomy, and 6.0% for radical prostatectomy. The SSI rates in clean surgery including open and laparoscopic nephrectomy/adrenalectomy were 0.7 and 1.4%, respectively. In SSIs, gram-positive cocci such as methicillin-resistant Staphylococcus aureus (58.8%) or Enterobacter faecalis (26.5%) were the most common pathogen. Similarly, the RI rate was the highest (35.2%) for surgery using intestinal urinary diversion, followed by 16.7% for surgery for lower urinary tract, 11.4% for nephroureterctomy, and 7.6% for radical prostatectomy, while RI rates for clean surgery were less than 5%. RIs most frequently reported were urinary tract infections (2.6%) where Pseudomonas aeruginosa (20.3%) and Enterobacter faecalis (15.3%) were the major causative microorganisms. Parameters such as age, obesity, nutritional status (low proteinemia), diabetes mellitus, lung disease, duration of operation, and blood loss volume were recognized as risk factors for SSI or RI in several operative procedures. Postoperative body temperatures, peripheral white blood counts, C reactive protein (CRP) levels in POD 3 were much higher than those in POD 2 in cases suffering from perioperative infections, especially suggesting that CRP could be a predictable marker for perioperative infections.

    ABSTRACT: We assessed the psychosocial well-being in cured testicular cancer patients who had undergone chemotherapy with or without retroperitoneal lymph node dissection, radiotherapy or surveillance therapy. The sample consisted of 83 cured testicular cancer patients of whom 34 had undergone cisplatin-based combination chemotherapy with or without retroperitoneal lymph node dissection (chemotherapy group), 42 had received infradiaphragmatic radiotherapy (radiotherapy group) and 7 had received surveillance therapy (surveillance group). The questionnaire reported demographic data, psychosocial well-being, working ability, satisfaction with life, relationships, and general health and fitness. For questions dealing with psychological distress there were no differences among the groups. However, a significant number of patients in all groups reported greater feelings of anxiety about health and future since treatment. Working ability was significantly better in the chemotherapy and radiotherapy groups than in the surveillance group (p < 0.05 and p < 0.01, respectively). Interestingly, the patients who received the most extensive treatment (chemotherapy plus retroperitoneal lymph node dissection) reported the best working ability. Using the satisfaction with life scale, patients in the chemotherapy and radiotherapy groups showed significantly higher scores than those in the surveillance group (p < 0.05). The majority of the patients reported no significant change in long-term relationships with family, friends and spouse. The development of psychosocial problems during long-term adjustment seems to be low regardless of treatment received. Although a significant number of patients reported a higher incidence of anxiety and depression since the illness, the overall attitude was positive toward life. With regard to treatment type, patients in the chemotherapy and radiotherapy groups had better working ability and greater satisfaction with life than the surveillance group.

    ABSTRACT: Despite improvement in the response rate and protraction of the progression-free period of urothelial cancer produced by chemotherapy, severe bone marrow suppression often results in delays in the initiation of treatment cycles and/or decreases in drug dosages. Reduction of leukopenia during chemotherapy has been demonstrated by the combined administration of granulocyte colony-stimulating factor (G-CSF) in various malignancies. A phase I/II study was conducted to assess whether the interval between cycles of CISCA (cyclophosphamide, doxorubicin, cisplatin) chemotherapy could be shortened under support of recombinant human granulocyte colony-stimulating factor (rhG-CSF) for urothelial cancer. Three or more patients with transitional cell carcinoma of the urinary tract were allocated to each of four different treatment intervals (step 1: 28 days, step 2: 21 days, step 3: 17 days, and step 4: 14 days) by reducing the interval in a step-wise manner. Two mg/kg/day of a rhG-CSF, lenograstim, was injected subcutaneously on days 3 to 16 (until day 14 for the 14-day interval group). Sixteen patients were enrolled, four patients were treated with the step 1 protocol, five with step 2, four with step 3, and three with step 4. Leukopenia/neutropenia was the most severe toxic reaction, but none of the patients at any step manifested neutropenia of WHO grade 4 for more than four days. There were no significant differences in the hematological and nonhematological toxicities among the 4 steps. Seven of eight patients with measurable diseases were treated with CISCA on shortened schedules (steps 2-4), and one complete remission (CR) and four partial responses (PR) were demonstrated. CISCA chemotherapy supported by rhG-CSF was safely shortened to a 14-day interval in the pilot study. The potential role of rhG-CSF in shortening the interval of CISCA, as well as the benefit of the intensified schedule, remains to be clarified.

    ABSTRACT: To assess prognostic factors in patients with metastatic nonseminomatous germ cell tumors, 50 patients with testicular germ cell tumors (TGCT) and 10 patients with extragonadal germ cell tumors (EGGCT) were studied. The clinical staging system for testicular tumors proposed by The Japanese Urological Association and The Japanese Pathological Society was applied. All patients with EGGCT had primary sites in the retroperitoneum. The 3-year survival rates of TGCT and EGGCT were 71.9% and 60.0%, respectively, and there were no differences in patient characteristics. Patients had significantly worse survival rates if the following applied: choriocarcinoma in the primary tumors, serum lactate dehydrogenase level greater than twice the upper limit of normal, liver, brain, or mediastinal metastases, or retroperitoneal tumors greater than 10 cm. It was concluded that the poor-risk group could be defined as those patients having lymph nodal disease only (stage II or III A) with retroperitoneal tumors greater than 10 cm, having pulmonary disease (stage III B) with retroperitoneal tumors greater than 5 cm, or liver, bone or brain metastases (stage III C), and these criteria will predict the prognosis for patients with advanced disease because the good-risk patients (53% of all patients) and poor-risk patients (47%) in this study had 3-year survival rates of 88.7% and 49.7% (p < 0.0001), and complete response rates of 96.9% and 60.7% (p < 0.005), respectively.

    ABSTRACT: A case of müellerian duct cyst with prostate cancer is reported. The patient was a 64-year-old male, complaining of hemospermia. Prostate cancer was suspected by rectal examination and a cystic mass was detected between the ejaculatory ducts by computed tomography and magnetic resonance imaging. He underwent a transperineal needle aspiration of the cyst. The fluid did not contain spermatozoa. A adenocarcinoma was detected from the prostate by needle biopsy. Therefore, a radical prostatectomy with the resection of the cyst was performed. This is the first report about the resection of müellerian duct cyst with the organs around it in Japan.

    ABSTRACT: The usefulness of preventive chemotherapy was studied in transurethrally prostatectomized patients with no prior urinary tract infections. They were divided into two groups (A and B) randomized by the envelope method. A was administered intravenously piperacillin (PIPC) 2 g once after surgery, and twice on the following day. B was similarly administered PIPC intravenously, followed by oral administration of tosufloxacin tosilate (TFLX) 300 mg twice daily from the second to the fifth day. Of the total of 135 cases, 104, 45 in A and 59 in B, conformed to the patient standards established for analysis. Efficacy was assessed by the primary physician and also according to a unified standard in which the onset of a post-surgical infection and a bacteriuria of 10(4) or greater CFU/ml observed ten days after surgery were regarded as ineffective. An intergroup statistically significant difference was not observed in the efficacy rate assessed by the primary physician. However, according to the unified standard assessment, B showed a significantly higher efficacy rate (88.1%) than A (62.2%). The administration of TFLX following PIPC was useful. With an indwelling catheter, B exhibited a significantly greater efficacy rate when the retention period was four days or longer. The efficacy was greater in both groups if lavage was not performed, and this effect was greater in A. Consequently, the administration of TFLX was considered more useful for long-term indwelling catheter cases. Neither serious side effects, nor clinical test abnormalities were observed in this study.

    ABSTRACT: We evaluated the clinical efficacy and safety of a Foley catheter coated with silver-protein (ProAg catheter) in the prevention of catheter-associated bacteriuria. ProAg catheter significantly reduced the incidence of extraluminal catheter-associated bacteriuria compared with usual latex Foley catheter although it did not inhibit intraluminal bacteriuria. There was no difference between ProAg catheter and latex catheter in the side effects such as urethral discharge, catheter-associated pain and allergic reaction. The ProAg catheter may be useful as an indwelling urethral catheter.

    ABSTRACT: We repose of chronic cystitis associated with alkali urine, struvite stones and a subsequent vesicorectal fistula caused by Corynebacterium sp, probably Corynebacterium group D2. We also studied in vitro and in vivo stone formation caused by Corynebacterium renale isolated clinically. C. renale inoculated into normal human urine increased urine pH and formed struvite crystals after a 24-hr incubation. Bladder stones were also formed in rats experimentally infected by C. renale as well as P. mirabilis. Some urea splitting species of Corynebacterium such as C. group D2 and C. renale may play a role in the formation of human struvite stone.

    ABSTRACT: We report a case of renal cell carcinoma with metastasis to the pancreas, treated by radical nephrectomy and total pancreatectomy. A 56-year-old man visited our hospital because of macrohematuria and right low backache. An intravenous pyelography, ultrasonography and a CT scan of the abdomen revealed right renal tumor at the upper portion, about 11 cm in diameter, but no abnormal findings of the pancreas. Aortic and celiac angiograms demonstrated multifocal lesions, 1 or 2 cm in size, compatible with a metastatic tumor in the region of the pancreas. The patient underwent right radical nephrectomy and open biopsy of the pancreas. The right renal tumor was histologically revealed to be renal cell carcinoma without nodal or venous extension. Histological examination of the pancreas biopsy specimen confirmed it to be a renal cell carcinoma metastatic to the pancreas. Therefore, he underwent total pancreatectomy 1 month after the previous surgery. Three months after the second surgery, a CT scan of the brain revealed metastasis to the pituitary gland. He is still under therapy.

    ABSTRACT: This is a report of the thirteenth known case in Japan of emphysematous cystitis. A 70-year-old man visited our hospital because of pollakisuria and macrohematuria on November 21, 1989. The patient had been known to have familiar amyloid polyneuropathy for the previous 3 years. Urinalysis showed marked hematopyuria. The residual urine was 216 cc, and urine cultures yielded 10,000,000 colonies of Escherichia coli per ml. Laboratory studies revealed systemic inflammatory findings, but no diabetic change. A plain X-ray film of the abdomen and an excretory urogram (DIP) showed small linear and round gas collections in the bladder shadow. A CT scan revealed multiple gas locules within the bladder wall. A diagnosis of emphysematous cystitis was established. The patient was given antibiotics, and there was striking clinical improvement. Histological examination of the endoscopically obtained biopsy specimen of the bladder revealed amyloidosis. We believe that this patient had a cystitis emphysematosa precipitated neurogenic bladder due to amyloid polyneuropathy and amyloidosis of the bladder.

    ABSTRACT: This is a report of the fifth case of pelvic lipomatosis in Japan. A 52-year-old man presented himself in our hospital with a complaint of left lower abdominal pain on August 28, 1988. At that time, physical examination was unremarkable with the exception of mild obesity. The excretory urogram and retrograde pyelogram revealed left hydroureteronephrosis with tapering of the left lower ureter. Urethrocystogram showed an elongated posterior urethra with anterior displacement and elevation of the bladder. Computed tomography revealed excess of diffuse fatty tissue in the pelvic space with bladder deformity and rectal compression. Pelvic arteriogram demonstrated no neovascularity. A diagnosis of pelvic lipomatosis was established. He lost 6 kg by diet therapy. Left lower abdominal pain disappeared, but excretory urogram after eight months showed no changes.

    ABSTRACT: The efficacy and safety of YM617, a new alpha 1-blocker, were evaluated in 121 patients with urinary obstruction of the lower urinary tract in the long-term administration study for 1 year. A total of 121 patients, i.e., 111 with benign prostatic hypertrophy (BPH), 6 with bladder neck sclerosis (BNS), 3 with BPH with BNS and 1 with female urinary obstruction, were orally administered 0.1 to 0.4 mg of YM617 once daily. Patients showing improvement of patient's impression and of subjective symptoms judged by the physician were increased until the 16th to 20th week, and it had been maintained there after. Objective findings were improved to a constant level after the 4th week. Patient's impression and subjective symptoms were improved in a certain dose-response relationship Side effects were observed in 3 patients but none were serious. YM617 proved to be useful in the treatment of patients with urinary obstruction of the lower urinary tract like BPH because it maintained the efficacy and safety in the long-term administration.

    ABSTRACT: We report a case of huge renal arteriovenous aneurysm, which was successfully treated with transcatheter arterial embolization (TAE). A 72-year-old woman was admitted with the clinical symptom of dyspnea on effort. She felt a tremor in the left abdomen. Computerized tomographic scan showed a large enhanced mass (8x7x7 cm) on the left kidney. Selective renal arteriography revealed a renal arteriovenous aneurysm. Transcatheter arterial embolization with a steel coil was performed with minimal loss of renal parenchyma. A total of 270 cases of arteriovenous fistula have been reported in Japan and were statistically analyzed. The number of reports on TAE has dramatically increased since 1978, TAE can be first indicated for treatment of renal arteriovenous fistula in view of less invasiveness and preservation of renal function.

    ABSTRACT: The cytotoxic effect of cis-diamminedichloroplatinum II (cisplatin, CDDP) on spermatogenesis in BALB/C mice, and possible protection of the testes by leuprolide acetate (D-Leu-6 LHRH(1-9)-ethylamide, TAP-144, leuprolide), a synthetic gonadotropin-releasing hormone analogue, were examined. Temporary interruption of the pituitary-gonadal axis by the analogue and amelioration of the gonadal toxicity of cisplatin by reducing the cell division rate in spermatogenesis were expected. The results showed cisplatin to have a cytotoxic effect on spermatogenic cells in BALB/C mice. The administration of leuprolide had no effect on testicular weight or histological findings in the mouse testes. Pretreatment and simultaneous administration of leuprolide did not reduce the damaging effect of cisplatin on the testes in mice. This is at variance with a previously published report.

    ABSTRACT: In the construction of a Kock continent ileal reservoir for urinary diversion, significantly high rates of late postoperative complications regarding nipple valves, the efferent limb in particular, have been reported. There are only a few reports on afferent nipple valve malfunction. A total of 42 patients who underwent a Kock pouch operation and were observed for more than 12 months (mean 38 months) was evaluated in terms of afferent nipple valve malfunction. Late afferent nipple valve complications were observed in 10 of the 42 patients (24%). These complications included erosion of the polyester fiber fabric used as a collar (5 patients), stenosis of the afferent limb (2) and obstruction of the afferent nipple by a mucous plug or fungus ball (3). The latter 2 complications were due to mechanical or dynamic obstruction of urine flow caused by a nonabsorbable collar. None of the 10 patients had problems with efferent nipple valve function. Our results suggest that the peristaltic direction of the intestine and the use of nonabsorbable material as a collar are primarily responsible for the late afferent nipple valve complications. Further modifications are needed to produce a stable nipple valve. Otherwise, simpler and more reliable alternative techniques of antireflux anastomosis should be considered.

    ABSTRACT: In order to elucidate the mechanism of elevation of alpha-fetoprotein (AFP) which we often observed during VAB-6 chemotherapy, we analyzed sequential changes of AFP, liver enzymes and bilirubin in 10 patients with evaluable disseminated testicular cancer who were treated with VAB-6 chemotherapy. None of the patients had previous liver disease or hepatic involvement. During the early phase of each course of chemotherapy, AFP showed a temporary elevation associated with reversible increase in liver enzymes and bilirubin. These changes returned to normal before the next course of chemotherapy. In each patient, marked tumor regression occurred as a result of VAB-6 chemotherapy. Nine of the 10 patients remain free of disease after treatment. We conclude that during VAB-6 chemotherapy, a temporary elevation of AFP is common, associated with reversible liver dysfunctions, and that this spurious elevation of the tumor marker, most likely caused by a heavy dose of cisplatin, should not be interpreted as related treatment failure.

    ABSTRACT: Construction of a continent ileal urinary reservoir (Kock pouch) is associated with a high incidence of late complication because of malfunction of the nipple valve, the efferent limb in particular. We have so far experienced several types of afferent nipple malfunction. We herein report on the unexpected complications of the afferent nipple valve in patients with a post operative observation of 1 year or more. From 1984 through 1989, urinary diversion via a Kock pouch was performed on 47 patients at Kyoto University Hospital and Public Toyooka Hospital. The study group comprises 42 patients with a mean observation of 40 months (range 14 to 60 months). The late complications of the afferent nipple valve were observed in 11 of the 42 (26%) patients. These included erosion of Dacron fabric used as a collar (5 patients), afferent nipple stenosis (3 patients) and afferent nipple obstruction by mucous plug or fungus ball (3 patients). Removal of Dacron collar was performed in 4 of the 5 patients with collar erosion and in 1 of the 3 patients with nipple stenosis. Nipple obstruction was relieved by endoscopic manipulation or diuresis. All of the 11 patients had no problems with their efferent nipples. Our results suggest that the use of nonabsorbable material as a collar and peristaltic direction of the afferent limb are mainly involved in the complications of the afferent nipple. A more reliable and simpler procedure for antireflux anastomosis should be considered.
