Malignant Teratoma of Prostatic Gland / 대한비뇨기과학회지

A teratoma is a true tumor which is composed of a variety of cell types representative of more than one germ layer. These neoplasms are principally encountered in the ovaries and testes. Rarely teratoma arises in the midline of the body such as anterior mediastinum, retroperitoneum, sacrococcygeal region, intracranial cavity, neck, and abdominal viscera, presumably from primitive sequestrated cell nests during embryogenesis. The teratoma is mostly benign in histology and biology, however, rarely cancer develops in preexisting benign cystic teratoma. The prostatic gland is an unusual site of the teratoma and so we report a case of teratoma which arose in the prostatic gland and underwent malignant change.

A Clinical Observation on Urinary Lithiasis / 대한비뇨기과학회지

A clinical observation was made on 150 patients of urolithiasis who admitted to the Department of Urology, National Seoul Hospital during the 5 years period from January, 1976 to December. 1980.

The most surgical intervention was ureterolithotomy in 25.3%. 9. The results of chemical analysis of 76 urinary calculi showed the mixed type of calcium phosphate and calcium oxalate in 38.2% (29 cases), calcium phosphate in 18.4% (14 cases), calcium oxalate in 15.8% (12 cases), the mixed type of calcium phosphate and ammonium phosphate in 11.8% (9 cases) and calcium carbonate in 5.3% (1 cases). The major component of urinary calculi was calcium-phosphate oxalate.

Clinical Observation on Benign Prostatic Hypertrophy / 대한비뇨기과학회지

A clinical observation was made on forty-three cases of benign prostatic hypertrophy, admitted to the Department of Urology, National Seoul Hospital during the period from January 1, 1977 to December 31, 1980. The results were summerized as follows. 1. The incidence of benign prostatic hypertrophy was 10.9% to 396 total in-patients and 34.4% to male in-patients 50 years old or more. 2. Most of patients were in the 7th and 8th decades of life (83.7%) with a mean age of 73.5 years old. 3. The mean average hospital period was 12.4 days. 4.

The mean volume of residual urine was 430ml. 6. Hematuria it 28cases (65.1%) and pyuria was revealed in 12 cases (27.9%). 7. I.V.P was performed in 34 cases and hydronephrosis was found in 5 cases (14.7%) and hydroureter in 4 cases (11.8%). Cystourethrography was performed in 31 cases, and elevated bladder base in 23 cases (74.2%) and trabeculation of bladder in 21 cases (67.7%). 8. Endoscopy was performed in 32 cases, The common findings were trabeculation in 28 cases (87.5%) and inflammations in 25 cases(78.1%). 9. Associated conditions with B.P.H. were hypertension in 6 cases (14.0%) and pulmonary tuberculosis in 5 cases (16.1%). 10. Management was done with retropubic prostatectomy in 16 cases, transurethral prostatectomy in 3 cases and suprapubic transvesical prostatectomy in 3 cases. 11. The mean weight of the removed adenoma was 34.2gm. 12. The mean duration of the indwelling catheter was 8.2 days. 13. The mean amount of transfused blood was 1. 78 pints. 14. Postoperative complications were urinary infection in lt cases (63.6%), temporary incontinence in 12cases (54.5%), epididymitis in 3 cases (13.6%), urethral stricture and rebleeding in each 2 cages (9.1%), delayed wound healing and pyrexia in each 1 case (4.5%). The mortality rate was 0%.

Retroperitoneal Cyst / 대한비뇨기과학회지

The retroperitoneal space is that indefinite area in the lumber and iliac region which lies between the peritoneum and the posterior wall of the abdominal cavity. The term retroperitoneal cyst or tumor is usually confined by the pathologist to these arising from the structures situated in the retroperitoneal space. Retroperitoneal cysts are that of non-neoplastic nature and originated from retroperitoneal tumor Because the retroperitoneal space is rather extensive and adjacent organs are easily displaced, many of the cysts grow to a large size before giving any clinical manifestation. Frequently, when the patient is first seen, there is an indefinite abdominal mass the exact nature of which is obscure, and the diagnosis is not made until the time of surgical investigation.

Statistical Observation on In-patients of the Department of Urology in the Past 3 Years / 대한비뇨기과학회지

A statistical observation was made on 267 in-patients with age distribution and operative procedures in the Department of Urology, National Seoul Hospital, during the period from January 1. 1976 to December 31, 1978.
