Recently, extensive uses of lectins as cytochemical markers have made of studies for various epithelial and nonepithelial neoplasia, however, investigations of epithelial cell surface of transitional cell carcinomas of the urinary bladder have been few. Thus, the atuhors performed a study of PNA binding in the authors performed a study of PNA binding in transitional cell carcinomas with comparision with that in normal mucosa of the urinary bladder to allow more accurate diagnosis and histological grade or degree of differentiation. The results of this study are as follows: 1) PNA shows negative reactions on all ten normal mucosae of the urinary bladder but positive staining at the glycocalyx of umbrellar cells in two cases. 2) PNA shows negative reactions on all four cases of von Brun'n nests and cystitis cystica. 3) PNA shows positive reactions on thirty (50%) of total sixty-one cases of transitional cell carcinomas and reveals two (20%), nine (41%), eleven (55%) and eight (88%) cases in grade I, II, III and IV, respectively. 4) PNA shows positive reactions on the intracytoplasm and/or degree of PNA binding activity in grade I to IV transitional cell carcinomas is not statistically significantly different (p>0.05). In summary, PNA did not react with normal nucosa and metaplastic lesions such as von Brunn's nests and cystitis cystica, however, it reacted with 50% (30/61 cases) of transitional cell carcinoma and its positivity is significantly increased with gradings of transitional cell carcinomas (p<0.05).

Various clinical evaluations in urological aspects were performed on 100 renal transplantations in the Department of Urology, Kosin Medical College from December 1984 to August l988. The following results were obtained. 1. Year distributions were as follows : 1 case was done in 1984, 5 cases in 1986, 31 cases in 1986, 30 cases in 1987, 33 cases in 1988. 2. Of 100 donors 44 cases were male and 56 cases were female. Sixth decade was most common. Of 100 recipients 71 cases were male and 29 cases were female. Fourth decade was must common. 3. Of all living-related donors 89 cases were related donors and 11 cases were unrelated donors. 4. The most common underlying renal disease requiring transplantation was chronic glomerulonephritis (90%) and reflux nephropathy was 2 cases(2 %). 5. All surgical approaches of donor nephrectomy were flank incision, usually with removal of 12th rib(59%). Selected kidney side was follow : 79 cases were left side and 21 cases was right side. 6. The ureteroneocystostomy was performed with modified Politano-Leadbetter method in initial 3 cases and extravesical Mac Kinnon method in 97 cases. 7. Our incidence of urological complications in 100 renal transplantations was 8%(8 cases). 6 cases were ureteral obstructions due to perinephric hematoma, 1 case was ureterotaneous fistula and 1 cases was bladder leakage. 8. Our incidence of complications in 100 donor nephrectomy was 3%(3 cases). 1 case was pleural effusion, 1 case was atelectasis and 1 case was perforation of stomach. 9. Results and prognosis in complicated cases were good.

Loss of the urethral floor with total urinary incontinence is a difficult problem that is infrequently encountered by the urologist. The techniques required for the urethral reconstruction are different and can be much more; delicate and demanding than the typical vesicovaginal fistula repair. Herein we report a case of the female urethral loss caused by chemical injury 3 years age and treated using bulbocavernous myocutaneous flap successfully.

Failure in the formation of a hymeneal orifice is a rare congenital malformation. There are many cases of imperforated hymen with hematocolpos in literature. However this condition associated with obstructive uropathy such as acute urinary retention is rare. We experienced a case of imperforated hymen with hematocolpos which caused acute urinary retention in a 16-year-old girl. Herein we report this case with brief review of literature.

The ureteral fistula is the most common urologic complication and it usually occurs within the first 3 weeks after renal transplantation. The dominant cause is damage to the arterial supply of the transplanted ureter by close dissection at time of donor nephrectomy. The signs and symptoms of ureteral fistula can mimmic acute rejection, which is oliguria, anuria, fever, wound tenderness, swelling and decreased renal function. It was well established that open intervention was standardized for such problem. Recently nonoperative percutaneous approaches to the placement of stents and tubes are used. Herein we report a case of ureteral fistula, misdiagnosed as acute rejection after renal transplantation, which was healed with Silastic drain insertion in a 22-year-old male recipient.

Hemangiopericytoma of the kidney is extremely rare, which is very much resembled a renal cell carcinoma. It tends to grow slowly but occasionally had demonstrated rapid infiltration and distant metastasis. The incidence and degree of its malignancy appears to be low. Herein we report a case of hemangiopericytoma which was developed from left kidney in 42 old man and treated with radical nephrectomy.
