Ultrasound is effective in evaluating pathologic entities of renal and bladder diseases. The advantage of the ultrasound scanning is no harmful, not need preparation, more comfortable and cheaper than other diagnostic methods with relative high diagnostic accuracy. Also ultrasound seems good primary screening test with I.V.P. in urologic diseases. So we made a brief clinical observation and reported with review of literature.

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.

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

There have been much limitations and errors in evaluating prostatic conditions by traditional radiologic methods due to its location and anatomical structure. However recent introduction and improvement of the ultrasonography have been enabled us to visualize boundary of the prostate clearly and differentiate the variable findings within the prostate. Transrectal or transurethral ultrasonography of the prostate is popular nowadays, however we performed suprapubic ultrasonography of which merits are traumatic to the patients, easy to perform and it requires no adjustments or additions to basic ultrasound equipment. In order to evaluate ultrasonogram of the prostate in patients with prostatic diseases and normal adults and compare preoperative volume of the prostate on ultrasonographic estimation with postoperative volume, 31 patients with prostatic diseases and 40 normal adults under the age 60 were studied with suprapubic ultrasonography. The results obtained were as follows. 1. On ultrasonographic picture of the prostate, normal adults showed symmetrical or triangular or elliptical appearance and there were numerous fine homogenous spots within the prostate. BPH patients showed symmetric, round or oval shapes and its margin was smooth and numerous fine spots were seen within the prostate as normal adults. The prostatic size enlarged and elevated to the bladder base. Advanced prostatic cancer patients showed dyssymmetric irregular appearance. The prostate of acute prostatitis patients resembled normal prostate but prostatic size enlarged. 2. The mean prostatic volume of normal adults on ultrasonographic estimation was 21.30+/-24.80 cm3 and there were no differences of the prostatic volume between ages. 3. The mean prostatic volume of 21 BPH patients on ultrasonographic estimation was 46.2+/-17.2 cm3 and majority patients were in 33.49-61.56 cm3. 4. Comparisonal studies between preoperative ultrasonographic prostatic volume and resected prostatic volume showed correlation coefficient 0.98 (P<0.005) and mean error rate 17.58+/-8.1%. Most cases showed preoperative prostatic volume was larger than the postoperative volume which was probably due to inadequate removal of tissue and surgical capsule. As results of the above, the suprapubic ultrasonography was helpful in differential diagnosis of the prostatic diseases and estimation of the prostatic size.

Histopathologic study was performed to observe the effects of M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin), widely used for advanced bladder cancer and its metastatic lesion, on the visceral organs of the experimental animal. M-VAC was used intraperitoneally throughout the study and the following results were obtained : 1. There were severe adhesions of visceral organs in all of experimental groups, compared with the control group. 2. Compared with the control group(15.0%), significant increase of incidence in renal cystic changes in experimental group(89.6%) was observed. The lesions were similar to polycystic kidney type I and considered to be irreversible. Therefore, ultrasonography of the kidney during the M-VAC regimen may be clinically worthwhile. 3. Portal triaditis ( 27.5% ) and fatty metamorphosis of the liver(24.1%) were observed significantly in the experimental group but they were limited, localized changes and thought to be reversible. Deterioration in hepatic function may not be seriously considered.

Granular cell tumor (GCT) is a benign neoplasm that frequently occurs in the skin, subcutaneous tissue, and oral cavity, although these tumors occur throughout the body. GCT of the bladder is an extremely rare disease, and only 10 cases have been reported. We report the use of ultrasonography and MRI for a case of GCT of the bladder; this lesion was pathologically confirmed.

OBJECTIVE: This study was designed to assess the usefulness of transperineal ultrasonography (US) for the determination of imperforate anus (IA) type. MATERIALS AND METHODS:From January 2000 to December 2004, 46 of 193 patients with an IA underwent transperineal US prior to corrective surgery. Sonographic findings were reviewed to identify the presence of internal fistulas and to determine "distal rectal pouch to perineum (P-P)" distances. IA types were determined based on the sonographic findings, and the diagnostic accuracy of transperineal US was evaluated based on surgical findings. RESULTS: Of the 46 patients, 17 patients were surgically confirmed as having a high-type IA, three patients were confirmed as having an intermediate-type IA and 26 patients were confirmed as having a low-type IA. The IA type was correctly diagnosed by the use of transperineal US in 39 of the 46 patients (85%). In 14 of the 17 patients with a high-type IA, internal fistulas were correctly identified. All cases with a P-P distance > 16 mm were high-type IAs and all cases with a P-P distance < 5 mm were low-type IAs. CONCLUSION: Transperineal US is a good diagnostic modality for the identification of internal fistulas in cases of high-type IA and for defining the IA level.

Primary vesical actinomycosis is an extremely rare disease. In most cases it is misdiagnosed as vesical or urachal tumor and usually diagnosed through post-operative pathologic confirmation. Here we report a case of primary vesical actinomycosis confirmed by preoperative repeated multiple transabdominal biopsies. The patient was a 49-yr-old woman who presented with frequency, dysuria, and intermittent gross hematuria for 2 months. Computed tomography and cystoscopic examination showed broad-based, edematous, and protruding mass at the dome and anterior portion of the bladder. The clinical and imaging findings of the patient initially suggested vesical malignancy. Transurethral resection and multiple biopsies of the mass were performed. Pathologic examination demonstrated fibrosis with chronic inflammation. We performed repeated transabdominal multiple needle biopsies for further pathologic confirmation. Histopathologic examination demonstrated typical sulfur granules, which were consistent with actinomycosis.

PURPOSE: To evaluate the impact of preoperative patient characteristics and flow rate on failure, early postoperative complications, and voiding in patients who underwent transvaginal tension-free vaginal tape-obturator (TVT-O) treatment for uncomplicated stress urinary incontinence (SUI). METHODS: We retrospectively reviewed patients who underwent TVT-O for SUI at 3 Italian centres. The exclusion criteria were predominant voiding and storage symptoms suggestive of detrusor overactivity, the presence of grade >1 urogenital prolapse, previous pelvic radiotherapy or other clinical contraindications for surgical procedures, neurogenic bladder dysfunction, and collagen diseases. Multivariate logistic regression models were constructed to identify predictors of early voiding dysfunction after TVT-O. RESULTS: A total of 219 patients underwent TVT-O between January 2010 and December 2015. All patients received follow-up at 3, 6, and 12 months, and underwent a stress test, uroflowmetry, and bladder ultrasound to evaluate the postvoid residual volume. They also responded to the Urogenital Distress Inventory (UDI-6) questionnaire. The rates of persistent incontinence after TVT-O, postoperative complications, and satisfaction were 16.4% (36 of 219), 24.2% (53 of 219), and 86.3% (189 of 219), respectively. Nineteen patients (9.5%) experienced early voiding dysfunction. Based on an analysis of baseline characteristics, we determined that a cutoff value of 9.0 on the UDI-6 predicted postoperative SUI with 62% specificity, 72% sensitivity, and 66% accuracy. In the multivariate logistic regression analysis, a preoperative UDI-6≥9.0 was an independent predictor of postoperative SUI. The predictors of complications were menopause (P = 0.04) and the preoperative UDI-6 score (P = 0.01). CONCLUSIONS: Menopause and UDI-6 scores could be prognostic factors for persistent SUI after TVT-O. Well-designed prospective studies with a suitable number of patients are needed to corroborate our findings.
