Radical cystectomy for bladder cancer was preformed in total of 68 consecutive patients (53 males and 15 females) at Binh Dan hospital from August 2001 to August 2003. Histopathological examination revealed that the tumor grade was 1 in 19 patients (2 with positive node), grade 2 in 20 patients (10 positive node) and grade 3 in 28 patients (15 positive node). The pathological stage was pT1 in 2 patients (no positive node), pT2 in 50 patients (17 positive node), pT3 in 15 patients (12 positive node) and pT4 in 1 patient (positive node). Among 68 patients underwent radical cystectomy, 35 patients had cultaneous ureterostomy, 26 patients had a Carmey II plasty with ileal-conduct uriary diversion, 5 patients with urinary diversion of Kock plasty and 2 patients had a Bricker operation

The overactive bladder, according to the original definition by International Continence Society refers to the storage phase of the bladder and is diagnosed by urodynamics. The overactive bladder is a medical condition referring to the symptoms of frequency and urgency, with or without urge incontinence, in the absence of local pathology or metabolic factors that would account for these symptoms. The definition of overactive bladder needs clarification, which would help to overcome the current confusion. Possible neurological, muscular, and metabolic causes have been proposed but in many cases the exact causes remain unclear. The diagnosis depends greatly on a detailed history, clinical examination, and urinalysis. Urodynamic evaluation is indicated when neuropathy is suspected, and the treatment may be unsuccessful without exact knowledge of patients' state. It can be treated conservatively by bladder training, physiotherapy, and drugs alone or with combination. For refractory cases neuromodulation, denervation techniques, and bladder augmentation or substitution can be used with good results.

Residual urine can be erroneously estimated due to cystic pelvic pathology by portable ultrasound scanning. We report a case involving a false-positive elevated postvoid residual urine result using a bladder ultrasound caused by an ovarian cystadenoma unrelated to the urinary tract.

We report a primary choriocarcinoma of the urinary bladder in a 63-year-old man who presented with painless hematuria. He was diagnosed as having an invasive carcinoma and underwent a total cystectomy. The tumor was diffusely hemorrhagic and occupied the dome of the bladder. Histologically, it consisted of cyto-and syncytiotrophoblasts with extensive hemorrhage. No coexisting transitional cell carcinoma component was present. By immunohistochemistry, the tumor expressed beta-hCG and low-molecular weight cytokeratin intensely while it was negative for CEA or EMA. The post-cystectomy serum beta-hCG was 237mlU/ml, and decreased later. The pertinent literature is reviewed and diagnostic criteria are discussed.

In order to study the association between lower urinary tract infection and cystitis glandularis (CG), 120 cases of CG were diagnosed by cystoscopic biopsy in the suspicious foci of the bladder. Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3% (11/72), and gray zone rate was 18.1% (13/72). 31.9% (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67%. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.

Recently, to find a change of cellular immunologic function, the development of monoclonal anti-body for surface antigen of T cell subsets is used as an important method of quantitative and functional measure in T cell subsets. We evaluated the T cell subsets in the peripheral blood of 145 normal control group and 106 bladder cancer group which was diagnosed by tissue pathology during the period from June 1986 to June 1992. The results of this study showed that CD3 of T cell subsets was significantly decreased in bladder cancer group as compared with normal control group(p<0.05) and significantly decreased in T1 and T1 groups of bladder cancer groups(p<0.05). But CD4/CD8 ratio was not decreased in bladder cancer group as compared with normal control group.

An ultrasonic scanner in the field of urology is described that can be used for transurethral as well as for transrectal scanning of the bladder and prostate. The bladder was visualized best by transurethral scanning, while the rectal approach was preferable for examination of the prostate. Transurethral ultrasonography was performed in 7 patients with bladder cancer. Transrectal ultrasonography was performed in 21 controls and 41 patients with prostatic disease. The following results were obtained: 1. Diagnostic accuracy of the staging of transurethral ultrasonography was 85.7% in bladder cancer. 2. The average values of maximum anterioposterior, superio-inferior and transverse diameter. obtained from ultrasonogram were 2.43+/-0.29cm, 3.27+/-0.41cm, 4.07+/-0.91cm in control group ;3.11+/-0.6lcm, 4.16+/-0.66 cm, 4.71+/-0.76cm in B.P.H.; 3.65+/-0.46cm, 4.88+/-0.23cm, 5.98+/-0.18cm in prostatic cancer. 3. Diagnostic accuracy of transrectal ultrasonography was 93% in B.P.H. and 80% in prostatic cancer. 4. Transurethral ultrasonography enabled us to determine the degree of tumor invasion of the bladder wall and was useful to help select appropriate therapy. Transrectal ultrasonography has proved especially in estimating prostatic size and in detecting pathology.

BACKGROUND: Pathologic grading, one of the most important prognostic factors of papillary urothelial neoplasia (PUN) of the urinary bladder, has been revised continuously. The current study focused on the analysis of interobserver agreement on PUN of the urinary bladder bet- ween 1973 WHO classification (WHO 1973) and 1998 WHO/ISUP classification. METHODS: Seventy five cases from 15 institutions were collected, and after review by Korean Society of Urogenital Pathology (KSUP), 30 cases were selected as follows; group I, WHO grade 1 and papillary urothelial neoplasm of low malignant potential by ISUP (7 cases), group II, WHO grade 2 and low-grade papillary urothelial carcinoma (16 cases), and group III, WHO grade 3 and high-grade papillary urothelial carcinoma (7 cases). Seventy five general surgical pathologists who participated in this study were asked to grade the tumors based on WHO/ISUP classification. Interobserver agreement between the participants' diagnosis and KSUP consensus diagnosis was analyzed by kappa value. RESULTS: Interobserver agreement assessed by kappa value for all diagnostic groups was very low; for group I, kappa value was -0.900893722; for group II, -0.944650025, and for group III, -0.876728996. The overall kappa value of pathology residents was better than that of practicing pathologists. CONCLUSIONS: The 1998 WHO/ ISUP classification could not be easily translated from the 1973 WHO classification and because of poor interobserver agreement, it appears that further work would be needed before it can be practically applied.
