During the period of 10.6 years from January, 1974 to June, 1984, clinical observations were made en 28 patients with multiple urothelial tumors involving 2 or more sites among renal pelvis, ureter, bladder and urethra. Out of 28 patients 1 multiple urothelial tumors, 7 had renal pelvis and ureteral tumor, 12 had upper urinary tract and bladder tumor, and 9 had bladder and urethral tumor. The results were as follows 1. 7 patients c renal pelvis and concomitant ureter tumor mostly had higher grade and higher stage tumors. 2. 12 patients c upper urinary tract and concomitant or subsequent development of bladder tumor usually had higher grade and higher stage tumors. 3. Patients having bladder tumor c urethral tumor showed multiple bladder tumors in 8 out of 9 cases, bladder neck lesion were in 7 of 9 cases. The location of urethral tumors showed 2 cases at anterior urethra and 8 cases at posterior urethra. The shape of urethral tumors showed papillary type in 3 cases and non-papillary type in 5 cases.

Inverted papilloma of the urinary tract is a rare finding, and it is almost benign in its histologic morphology and clinical behavior. Despite several published reports, the prognostic significance and potential clinical behavior of this malady remains unclear. The most commonly associated clinical symptoms are hematuria and obstruction of the urinary tract. Most inverted papillomas of urinary tract occur in the bladder and only rarely in the ureter, renal pelvis and urethra. We report here on one case of inverted papilloma in the prostatic urethra. This was diagnosed by transrectal ultrasonography and confirmed by its histology.

Cholesteatoma of the urinary tract is an extremely rare disease occurring in the bladder and renal pelvis. We report the radiologic findings in two cases of renal cholesteatoma involving the renal pelvis, calyces and ureter, and correlate these with the histopathologic findings.

Epithelioma of the urinary tract is rare and arises in the kidney, ureter and bladder. Herein, the authors describe clinical experiences with 4 patients who had nephroureterectomy for renal pelvis tumor between August 1970 and July 1971 at the Department of Urology, Presbyterian Medical Center, Taegu, Korea.

Transitional cell carcinoma of the upper urinary tract is distinguished from other genitourinary malignancy by its tendency to be part of a generalized abnormality that affects the entire urothelium and causes multiple tumors. We analyzed retrospectively 30 patients who underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis and ureter. High stage upper urinary tract transitional cell carcinoma and a history of synchronous bladder transitional cell carcinoma were adverse prognostic factors. We observed increased incidence of additional urothelial tumors in more than 50 per cent of patients, especially on the involved side, which mandated radical nephroureterectomy including a bladder cuff as the treatment of choice.

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall incidence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

Imaging features of metastases to the urinary system may closely mimic primary urinary tract tumors, and differential diagnosis by imaging alone may be problematic or even impossible in some cases. The main purpose of this article was to familiarize radiologists with imaging findings of metastasis to the urinary system on cross-sectional imaging, with an emphasis on abdominal and pelvic computed tomography and magnetic resonance imaging. In addition, we review the clinical importance and implications of metastases to the urinary tract and provide information on diagnostic work-ups.

A clinical observation was made on 127 patients with bladder tumor, admitted to the Department of Urology, Chonnam University Medical School Hospital during the period from January, 1979 to December, 1984. The following results were obtained: 1. There were 127 patients with bladder tumor, being 5.4 percent of a total of 2,360 in-patients during the period. 2. Of the patients with bladder tumor, 106 were males and 21 females with a ratio of 5 to 1 Ages were ranged from 6 months to 84 years with a mean age of 51.9 years and 81.1 percent of the patients being over 50 years of age. 3. The most common symptom was gross hematuria in 94.5 percent of the patients and frequency in 15.7 percent painful urination in 12.6 percent and dysuria in 10.2 percent were observed in order. Seventy four percent of the patients came with 1 year of their first trouble and only 3.1 percent delayed more than 5 years. 4. Of 124 patient, 40 (32.3 percent) had tumors in the posterior wall of the bladder and 83 (66.9 percent) had single tumor when first seen. 5. Of 114 patients on which an IVP was performed, 78 (68.4 percent) revealed normal upper urinary tracts and 85 (74.6 percent) showed filling defects in the bladder. 6. The most common of the associated diseases were hypertension in 11 cases and benign prostatic hyperplasia in 10. Concurrent transitional cell carcinoma in the renal pelvis and/or ureter or urethra were found in 11 patients (8.7 percent) of 127 patients with bladder tumor. Different malignancies developed in other organs except the bladder were associated in 10 patients (7.9 percent) of 127 patients with bladder tumor all their lives. 7. Pathologic examination of specimens from 111 cases revealed transitional cell carcinoma in 102 (91.9 percent). Classified according to the grade and stage, the most common was grade II found in 49 cases (44.2 percent) and stage A observed in 49 cases (44.2 percent). 8. A total of 155 operations, including 39 subsequent operations for recurrences was performed on 116 patients. They were 55 TUR, 36 open resection, 43 partial cystectomy, 20 total cystectomy with ileal conduit and 1 suprapubic cystostomy. 9. There were 47 recurrences in 35 (41.7 percent) of 84 patients initially operated and followed up. Of these recurrences, 24 (51.1 percent) occurred within 1 year of followup. Tumor recurrences were observed in 31 (81.6 percent) of 38 patients treated by surgery only, but in 16 (32.0%) of 50 patients treated by surgery plus intravesical chemotherapy.

During the period, Jan. 1961 to Sept. 1962. 77 cases of urinary tract calculi were seen at the C.A.H. This is 1.13% of all ambulatory patients seen at the urology section. Commonest sites were, ureter (63.6%), bladder (18.2%), kidney (9.1%) and urethra (9.1%) in that order. In age distribution, 21-25 years old was the highest (52.1%), and this might reflect the nature of the military hospital. In management, ureterolithotomy was the most commonly used procedure (31.2%), 20.8% of the cases were managed non-operating. Phosphate and oxalates stone were found more commonly in upper urinary tracts. Their break down was as follow; Phosphates 46.8%, Oxalates 23.8%, Oxalates and Phosphates 10.4%, The other properties 19.0%.

Inverted papilloma is a rare urothelial neoplasm most frequently occurred in the trigonal region of the urinary bladder. But, it rarely arises in the renal pelvis. The characteristic downward proliferation of urothelial cells within the underlying lamina propria is of such magnitude as to result in an exophytic papillomatous tumor. It was regarded as a benign neoplasm, but the malignant tendency is now being reported with inverted papillomas of urinary tract, and therefore they are no longer regarded as innocuous benign neoplasms. We report a very rare case of inverted papilloma of the renal pelvis and review the relevant literatures.
