    Notes: Background At Kobe University Hospital we have created orthotopic neobladders since 1988 by using several colonic segments. Various types of neobladders were compared and a detailed description of these procedures and the voiding function outcome is presented. Methods Thirty-two men with invasive bladder carcinoma or recurrent carcinoma in situ underwent a radical cystectomy followed by orthotopic neobladder replacement using a right colonic, ileocolic or sigmoid colonic segment. The functional capacity, percentage of residual urine volume, configuration of the neobladder, and location in the pelvis were evaluated 1 year after surgery. Voiding function was evaluated using a questionnaire which included questions on diurnal and nocturnal continence, and by uroflowmetric analysis. Results Operative time, blood loss, and functional neobladder capacity did not differ for the 3 types of neobladders. The configuration of the right colonic and ileocolic neobladders resembled the shape of a rugby ball. The configuration of the sigmoid neobladder was oval. The right colonic and ileocolic neobladders tended to be located along the right side wall of the pelvis. The sigmoid neobladder was located in the center of the pelvis. Daytime and nocturnal continence was not affected by either the type of neobladder or its configuration or position. Neobladders located in the center of the pelvis exhibited a better maximum flow rate than those located along the right wall of the pelvis. Conclusion The technical difficulty in constructing the 3 types of neobladders was approximately the same. For better voiding a neobladder should be located in the center of the pelvis.

    Notes: We report here the case of a 78-year-old man who, 15 months after orchiectomy for palliation of prostate adenocarcinoma, was diagnosed as having squamous cell carcinoma of the urinary bladder. The bladder cancer was treated surgically, including dissection of pelvic lymph nodes. Some of these nodes were observed at surgery to be swollen, and were found on pathologic examination to exhibit the collision phenomenon: the mixing and mingling of cancer cells representing 2 distinct topographic origins. This case suggests that the possibility of collision phenomenon should be considered whenever any metastasis (but especially one in the lymph nodes) is found in a patient diagnosed with 2 different types of cancer. Moreover, it reminds us that diagnosis of one type of cancer does not rule out the possibility of another.

    Notes: The detection rate of organ-confined prostate cancer by digital rectal examination (DRE), serum prostate-specific antigen (PSA), and transrectal ultrasound (TRUS) of the prostate, as well as the value of a directed, guided transrectal core biopsy for the prostate (TRUS-guided biopsy) combined with systematic biopsy, were evaluated. The subjects were 171 patients with urinary symptoms suggestive of prostatic disease excluding those with clinical stage C and D prostate cancer. Twenty-five patients (14.6%) had prostate cancer, 127 (74.2%) had benign prostate hypertrophy, four (2.3%) had prostatic intraepithelial neoplasia, eleven (6.4%) had inflammation, and four (2.3%) had normal prostate tissue. The incidence of detection of hypoechoic findings by TRUS in the patients in whom nodules were detected by DRE or who had elevated serum PSA was higher than that in patients with negative diagnostic findings. In 22 of the 25 patients with prostate cancer, the cancer was detected by recognition of a hypoechoic area on TRUS. In 10 of these 22 patients, prostate cancer was also detected by systematic biopsy in isoechoic areas. Prostate cancer was detected by systematic biopsy in three patients without hypoechoic findings. The positive predictive value for patients with abnormal findings on all three tests was 64.3%, which is significantly higher than that for patients with any other combination of findings (p 〈 0.05). Our results indicate that the combination of DRE, serum PSA and TRUS is useful for the detection of organ-confined prostate cancer, and that TRUS and TRUS-guided prostate biopsy combined with systematic biopsy should be performed in patients with abnormal findings for both DRE and PSA. Our results also demonstrate that systematic biopsy is useful for the detention of prostate cancer from the isoechoic area visualized by TRUS.

    Notes: Background:The clinical outcome of patients with renal cell carcinoma with brain metastasis was analyzed.Methods:Nine patients (median age, 60 years) with primary renal cell carcinoma and distant metastasis, including brain metastasis, were treated. The median time to the development of brain metastasis was 15 months after the initial visit. Patients with poor performance status or progressive disease were treated with interferon or conservative therapy alone. Patients with good performance status and other well-controlled metastatic foci were treated either with radiotherapy, or by tumorectomy of brain metastasis, or both. The median follow-up was 26 months after the initial visit.Results: The 1-year, cause-specific survival rate was 17%. Of the 5 patients treated with α-interferon alone, all died of disease after the treatments, without improvement of performance status, 1 to 4 months after the diagnosis of brain metastasis. Two of 4 patients who underwent radiotherapy were treated with a combination of γ-knife and tumorectomy of brain metastasis. They remained alive 10 and 22 months after diagnosis of brain metastasis. The 2 patients who underwent the combination treatment of γ-knife and tumorectomy showed improvement of their performance status after these treatments for brain metastasis.Conclusion:Brain metastasis is an unfavorable prognostic factor in renal cell carcinoma. Although a larger number of patients would be necessary to demonstrate the definitive effects of γ-knife treatment, our results suggest that the combination of γ-knife and tumorectomy of brain metastases may be recommended for selected patients with good performance status and other well-controlled metastatic foci.

    Notes: A titanium Greenfield inferior vena cava filter was used for the treatment of 2 patients with unresectable renal cell carcinomas with tumor thrombi to prevent a fatal pulmonary embolism induced by tumor clots released during systemic interferon therapy and embolization of the primary tumor. After treatment, the size of the renal cell carcinomas at the primary site and the tumor thrombi decreased by 50%. There were no fatal pulmonary embolisms or complications related to the filter during the observation period (24 and 25 months) after therapy. This method may be useful in the prevention of a fatal pulmonary embolism induced by embolization and systemic interferon therapy in these patients.

    Notes: Purpose: In order to evaluate precise anastomosis using a Foley catheter, complications following radical retropubic prostatectomy were examined.Methods: Twenty-one patients underwent radical retropubic prostatectomy. Precise vesicourethral anastomosis was performed, visualizing the urethral stump by raising up the urogenital diaphragm using a Foley catheter. Complications, such as prolonged urinary extravasation and temporary urinary retention, were checked when the catheter was removed. Incontinence was evaluated both within 6 weeks and more than 6 weeks after operation. Anastomotic and urethral strictures were also checked during follow up.Results: The follow-up period ranged from 4 to 47 months (mean (± SD) 22.0 ± 12.1 months). Eighteen of 21 patients (85.7%) achieved continence after the operation. However, two patients still had stress incontinence and one patient had mild incontinence. Neither prolonged urinary extravasation nor temporally urinary retention were observed. Anastomotic and urethral stricture were not experienced during follow up.Conclusions: Precise anastomosis using a Foley catheter is technically easy and useful, even for relatively inexperienced urologists, to perform. Patients can often achieve continence following this procedure.

    Notes: Background: The presence of proliferating cell nuclear antigen (PCNA) has been suggested as a more important prognostic marker than either grade or mitotic in the prognosis of patients with renal cell carcinoma. We assessed the immunoreactivity of PCNA in primary lesions and pulmonary metastases from patietns with renal cell carcinoma and correlated the results with various histopathologic features and prognostic factors. Methods: We studied the relationship between PCNA expression and clinical prognostic factors from resected primary lesions and pulmonary metastases from 10 patients and primary lesions from 32 patients with renal cell carcinoma without metastases. The cells were immunohistochemically stained with PCNA monoclonal antibody (PC-10) and 1000 nuclei were counted. The results were expressed as a ratio of stained to total cells (PCNA labeling index, LI |X%). Results: The PCNA LI of pulmonary metastatic nuclei was significantly higher than the PCNA LI of renal lesions either from patients with (P 〈 0.05) or without (P 〈 0.01) metastases. Also, the mean PCNA LI of the pulmonary lesions in patients dying within 3 years of diagnosis was higher than the mean PCNA LI of patients surviving greater than 3 years. Conclusion: Our findings suggest that the PCNA LI, which was determined by immunohistochemical analysis, is an important market reflecting the biologic behavior of renal cell carcinomas. The degree of PCNA expression in this study was of prognostic significance.

    Notes: Background:The application of an appendix stoma in a Mainz urinary reservoir pouch is an established procedure and assures good continence. We modified this method for use with a sigmoid pouch.Methods:In each of 3 men with bladder carcinoma, an appendix with a blood supply was prepared and anastomosed to the detubularized sigmoid pouch with a 3-cm submucosal tunnel.Results:In all 3 patients, this procedure was performed successfully, and the pouch was completely continent. Self-catheterization could be performed without difficulty by 2 patients, and with slight resistance in the remaining patient. The patients are satisfied with their quality of life.Conclusions:We conclude, based on our findings and these preliminary observations, that this procedure is a potentially good alternative for the placement of continent stoma in continent urinary reservoir surgery.

    Notes: Abstract A 58-year-old man presented with dysuria at the Osaka Medical College Hospital in November 1996. Laboratory examination revealed elevated serum prostate-specific antigen (PSA) to 〉 100 ng/mL. Adenocarcinoma of the prostate with metastasis to the bone was diagnosed after a biopsy of the prostate and bone scintigraphy; hormonal therapy was administered. Although bone metastasis was well controlled and the serum PSA level declined to within normal levels (2.0 ng/mL), several painless nodules were found on the penile glans. Biopsy of the nodules showed that the penile tumor was a metastasis from the prostate cancer. The patient underwent partial penectomy for relief from penile pain. The serum PSA level showed no elevation 3 months after the partial penectomy, suggesting that careful observation of prostate cancer patients is necessary, even when oseous metastasis is well controlled and serum PSA levels are kept within normal ranges by hormonal therapy. The case also indicates that urologists should consider the possibility of metastasis to the penis from prostate cancer.
