1.A Clinical Observation on Tumors of the Renal Pelvis and Ureter.
Korean Journal of Urology 1982;23(8):1105-1110
Primary tumor of the renal pelvis and ureter is relatively rare disease, but usually malignant. It's prognosis is dependent upon the early detection, accurate diagnosis, procedure for treatment, and tumor grade and stage. Therefore, urologist should endeavor after accurate diagnosis and definitive treatment. A clinical observation was done on the 11 patients with renal pelvic tumor and the 3 patients with ureteral tumor at the Department of Urology, Kyungpook National University Hospital during the period of 4 years from January, 1978 to December, 1981. The results were as follows: 1. There were 9 men and 5 women, giving a ratio of 1.8 to 1. The average age at presentation of the 14 patients was 51.4 years. 2. On excretory urogram, nonvisualization of the kidney was the most prevalent sign in 10 patients. Retrograde pyelogram was done in 11 patients in whom findings of IVP were not sufficient for diagnosis. Renal angi0graphy was done in 9 patients. 3. Urine cytology was positive in 2 of 14 patients. 4. Of the 13 patients treated, 12 were proved to have transitional cell carcinoma, and 1 was leiomyoma. In 3 of the 11 patients with renal pelvic tumor, Concomitant ureteral tumor was present at diagnosis. And in 2 of the 11 patients with renal pelvic tumor developed subsequent urothelial tumors in the ureter and/or bladder after simple nephrectomy. 5. Nephroureterectomy including resection of a bladder cuff was done in 11 patients, and in 2 of these was also performed lymphadenectomy. Simple nephrectomy was done in 2 patients with renal pelvic tumor under the misdiagnosis of renaltuberculosis. 6. Postoperative complications developed in 3 cases, wound infection, pneumothorax, and death, in each case.

PURPOSE: A retrospective review of the medical records of 168 patients who were evaluated for renal transplantation was undertaken to determine whether a voiding cystourethrography (VCUG) influenced the surgi cal care of the recipient. MATERIALS AND METHODS: Between June 1989 to May 1998, 168 patients received a transplantation at our center. These patients proceeded to transplantation, with all of them receiving a VCUG as part of their evaluation. We compared incidence of postoperative complications between normal VCUG group and abnormal group during follow up period (mean 31. 6 months). RESULTS: An urologic abnormality was identified by VCUG in 15 (8.9%) of 168 patients and all of them were vesicoureteral reflux (VUR). In 15 patients with VUR, grade of VUR were grade I in 2, grade II in 10, grade III in 2 and grade IV in 1. None of them with VUR required surgical intervention and had postoperative complications related to VUR. CONCLUSIONS: The VCUG is not essential for the preparation of potential recipients for renal transplantation and should be utilized selectively in individuals with a history of urologic disease or when urinary tract abnormalities are identified by physical examination or an abnormal urine analysis.

A clinical observation was made on 35 patients with renal tumor who had been admitted to the Department of Urology, Kyungpook University hospital during the period from January, 1975 to December, 1979. The following results were obtained; 1) The incidence of renal tumor among total 1, O29 inpatients was 3.4% and 16.3% among the 214 genitourinary tumors. The most prevalent age group was fifth decade. There were 22 men and 13 women, for a ratio of 1.7`1. 2) histopathological analysis showed renal cell carcinoma in 16 cases, transitional cell carcinoma in 5 cases and Wilms` tumor in 4 cases, in order of frequency. 3) The most frequent symptoms and signs were palpable mass in 51.4%, flank pain in 45.7% and gross hematuria in 42.8%, but these were seen as the classical symptom triad in 11.4% of the patients. 4) Renal angiography was performed in 14 patients with renal tumor. 7 renal cell carcinomas, 2 Wilms` tumors, 3 transitional cell carcinomas and 2 renal cysts were accurately diagnosed. S) At the time of diagnosis distant metastases were found in 6 patients with renal cell carcinoma. 6) Treatment of renal tumors consisted of surgery and adjuvant radiation and/or chemotherapy. In renal cell carcinoma 3 simple nephrectomies, 9 radical nephrectomies and l pedicle ligation only were done. Post-operative radiation or chemotherapy was performed in 2 cases. It patients with Wilms` tumor 1 simple nephrectomy, 3 radical nephrectomies were performed and in all the patients combined radiation and/or chemotherapy after surgery were Jone for cure of tumor. In 5 patients with transitional cell carcinoma, 2 patients underwent simple nephrectomy and 3 patients nephroureterectomy with bladder cuff resection.

A clinical evaluation was made with particular attention to surgical management on patients with staghorn calculi who had been admitted to the Department of Urology, Kyungpook National University Hospital during 10 years periods from January, 1975 to December, 1984. The results were as follows: 1. Out of total 2,634 in-patients, 469 were due to urinary stones and 51 due to staghorn calculi. 51 patients with staghorn calculi were 2% of total admission and 11% of patients with urinary stones. 2. The calculus was unilateral in 50 patients (right in 25 and left in 25) and bilateral in 1. Of 5O unilateral staghorn calculi l was in left solitary kidney. 3. 49 patients had presenting symptomatology and 2 patients had no symptoms. The most common symptom was flank Rain(80.4 %). 4. Excretory urogram showed marked hydronephrosis in 8 cases, mild to moderate hydronephrosis in 3O normal collecting system in 3 and non-visualized kidney in 10. 5. Urine cultures yielded organism in 19 of 41 cases: E. coli, Klebsiella and Staphylococci in 4 respectively and Enterobacter in 3. 6. The treatment modality was surgical intervention .in 47 patients (48 operations) and conservative management in 4. 4S surgical interventions were nephrectomy in 10 and conservative treatment 38. Conservative surgery was extended pyelolithotomy in 12, extended pyelolithotomy with parenchymal extension in 11, anatrophic nephrolithotomy in 9, partial nephrectomy in 5, and extended pyelolithotomy with ureterocalicostomy in 1. 7. Except 6 cases with remnant calculi, no mortality and significant morbidity was found in 38 cases with staghorn calculi treated by conservative surgery.

Korean Journal of Urology 1980;21(4):314-321
Seventy six patients with renal injury admitted to the Department of Urology, Kyungpook National University Hospital during the least 6 and a half years were reviewed with particular attention to diagnosis and management. The injuries in this series were classified as minor, major and critical injuries according to Hodges classification. 32 patients were classified into minor injury, 41 patients into major injury and 3 patients into critical injury. Excretory urography was obtained in 75 patients and renal angiography only in 6 patients. 31 patients with minor injury were treated conservatively. Conservative management was done in 23 of 41 patients with major injury and the remaining 18 patients were managed surgically. 15 of 18 patients treated surgically in major injury were managed with conservative surgery (renorrhaphy in 9, partial nephrectomy in 5 and symphysiectomy in 1) and remaining 3 patients with nephrectomy. In major injury, 7 out of 23 patients treated conservatively and 3 out of 9 patients managed with renorrhaphy required nephrectomy subsequently due to complicating illness.

Korean Journal of Urology 1973;14(2):105-108
Ureteroceles can be classified as intravesical forms which terminate inside the vesical cavity and ectopic ones which terminate in the vesical outlet, urethra, or elsewhere. Most intravesical ureteroceles do not require operative intervention, except when they are obstructive because of harboring calculi, upper tract dilation or infection, and when the function of the intramural portion of the ureter appears irreparably injured. Two cases of intravesical ureterocele including a calculus, occurring in female patients, 27 and 37 years old. are presented with a brief review of the literature.

Between January l986 and June l990. 86 cases with interventional uroradiologic procedure entered into the study. Of 86 cases, 54 procedures were performed via percutaneous route and 32 procedures via intravascular. 54 percutaneous procedures included 24 of puncture and aspiration (13 for renal abcess and 11 for renal cyst). 2 of uric acid stone dissolution and 20 of UPJ and ureteral management (11 for UPJ stricture. 8 for ureteral stricture and 1 for ureteral fistula). 32 intravascular procedures included 24 of transcatheter embolization (10 for kidney. 3 for bladder and 11 for internal spermatic vein) and 8 of transluminal angioplasty (6 for renovascular hypertension and 2 for renal artery stenosis after renal tansplantation). Complications occurred in 10 cases which consisted of severe bleeding in 3, sepsis in 3, chronic urinary tract infection in 2. high fever with flank pain in 1 and paresthesia of gluteal muscle in 1. These complications were managed by conservative treatments with no sequalae. The results of interventional uroradiologic procedures for the 86 cases revealed good in 52. fair in 19 and fail in 15.

8.A Clinical Observation on Tumors of the Genitourinary Tract.
Korean Journal of Urology 1982;23(4):442-450
A clinical observation was made on patients with the tumors of the genitourinary tract, who were admitted to the Department of Urology, Kyungpook National University Hospital during 10 years period from January 1970 to December 1979. Out of 1606 total hospital admissions. 284 were due to the tumors of the genitourinary tract, giving rate of 17.68%, sex ratio, male to female, was 6.89:1 The most frequently involved age group was the 7th decade, being 31% of total, followed by the 6th decade (22%). About 85.21% was seen at age of 40 and over. Prostate was the most commonly involved organ comprising 122 (42.96%) out of 284 cases of the tumors of the genitourinary tract, followed in frequency by bladder in 77 (27.11%), kidney in 40 (14.08%), and penis in 24 (8.45%). The tumors were benign in 123 and malignant in 161, giving ratio of benign to malignant approximately 1:1.3. The most common type among benign group was B.P.H. and among malignant type, bladder carcinoma. Pathologic diagnosis was performed on 174 cases. Out of these, 52 were diagnosed as transitional cell carcinoma of bladder, followed in frequency by B.P.H. in 36 and squamous cell carcinoma of penis in 16.

Korean Journal of Urology 1978;19(2):143-150
Fifty six urethroplasties performed from Jan. 1971 to Dec. 1976 at the Dept. of Urology, Kyung pook National University Hospital were reviewed respectively with particular attention to complications relating injury site to operative procedure. During the period the total number of patients with urethral injury was 71, of whom 56 under went a urethroplasty and the remaining 15 were treated conservatively. Of the 56 patients had urethroplasties 21 had for anterior urethral injury, in whom 13 underwent a primary realignment procedure and eight a perineal end-to-end anastomosis. Urethral stricture developed in seven(61. 5%) of the 13 primary realignment procedures, while in only one of the eight perineal end-to-end anastomoses. No impotence did occur in patients with the anterior urethral injury. Posterior urethroplasty was performed in 32 patients, of whom 30 had a primary realignment procedure and the remaining two a perineal end-to-end anastomosis with suprapubic cystostomy. Urethral stricture was developed in 20, impotence in seven, and fistula in two of the 30 primary realignment procedures. Results from the present study show that the primary realignment procedure is more likely to complicate urethral stricture regardless the site of injury, compared with the perineal end-to-end anastomosis.

10.Treatment of Hypospadias by the Byars Technique.
Korean Journal of Urology 1982;23(1):90-95
Byars hypospadias repair is known to be simple, sound and also giving the lowest incidence of fistula formation. The authors applied this technique to 25 patients with hypospadias in this department during 5 years period from January, 1976 to December, 1980. Fourteen patients presented with penoscrotal type, 5 penile type, 3 coronal type, and 3 scrotal type. Of these patients, 9 had chordectomy only, 11 chordectomy and secondary urethroplasty, and 5 with previous chordectomy attempted elsewhere urethroplasty only. Chordectomy were performed on 20 occasions and urethroplasty on 16 occasions. NO significant morbidity was seen related to this technique, except one patient with ureterocutaneous fistula which was treated subsequently by fistula repair.
