Clinical Observation on Undescended Testis: A Comparison Study of Palpable and Impalpable Undescended Testis / 대한비뇨기과학회지

The clinician is posed a serious clinical dilemma when confronted with absence of testis during surgical management of impalpable testis. Herein we performed a comparative clinical study of palpable and impalpable undescended testis in 135 patients, 150 undescended testes during the period from January, 1979 to June, 1984. The results were as follows: 1. Among the 150 undescended testes, 47 cases(31.3%), were impalpable undescended testes on physical examination. 2. In 135 patients of undescended testis, number of patients below 2 year-old(considered as optimal age of orchiopexy) were 15(11.1%) patients and below 10 year-old were 75(55.6%) patients. There was no marked difference of age distribution in patients of palpable and impalpable undescended testis. 3. Associated anomalies were found in 16 (11.9%) patients of total 135 patients, and twice more commonly found in the patients of impalpable undescended testis than palpable undescended testis. 4. As surgical location of undescended testis, abdominal type and absence of testis were more common in impalpable undescended testis (10.6% and 8.7% of cases) than palpable undescended testis (1% and 0% of cases).

Prophylactic Effectiveness of Intravesical Chemotherapy in Superficial Bladder Tumors / 대한비뇨기과학회지

Recurrence in patients with superficial bladder tumor is a serious problem. In one series, the recurrence rate was 73%, and invasive cancer developed in 10% of patients with recurrences. To eliminate or reduce the rate of recurrence, topical chemotherapy has been tried and showed adjunct effects. We studied to evaluate prophylactic effects of topical chemotherapy in 51 patients with superficial bladder tumor admitted to the Department of Urology, Kyung Hee University Hospital during the period from April, 1979 to April, 1984. Patients were divided into 2 groups. Group A comprised 19 patients (Adriamycin; 8, Thio-TEPA; 11) treated with topical chemotherapy following initial TUR and 27 patients treated by TUR only. Group B comprised 5 patients treated with topical chemotherapy (Adriamycin) after repeated TUR and 7 patients among 27 patients who had repeated TUR for recurrence. Patients treated by TUR only were defined as control group. Recurrence rate was analyzed in each group. Following results were obtained. 1. In group A, recurrence rate was 2.54 in patients with chemotherapy comparing to 3.35 in control patients. Average interval of recurrence was 39.3 months in chemotherapy patients and 29.8 months in control patients. 2. In group B, recurrence rate was higher in chemotherapy patients than in control patients with rate of 6.6 and 5.3, respectively. But recurrence rate was diminished to 6.6 after chemotherapy comparing to pre-chemotherapy period (10.3). 3. There was no difference in recurrence rate relating to multiplicity of tumor as a whole.

A Case of Self-Mutilation of Penis / 대한비뇨기과학회지

Amputation of penis occurs most commonly as an act of self-emasculation. Fortunately, complete amputation of penis is quite rare but potentially devastating occurrence. Reimplantation of the penis has both cosmetic and functional objectives. Recently, several successful applications of microvascular technique to reimplantation of the amputated penis have been reported. Also herein, we present a case of successful reimplantation of completely amputated penis by using a microvascular repair.

The Cell Surface Antigen A,B,O(H) as An Indicator of Malignant Potential in Bladder Carcinoma: A Preliminary Report / 대한비뇨기과학회지

Currently, the cell surface antigen A,B,O(H) is thought to be an important indicator of malignant potential in bladder carcinoma. Herein, we performed SRCA test in 54 bladder carcinoma for detection of such an isoantigen, comparing the SRCA result to its tumor grade and stage. Also, various significances including the clinical application of SRCA test for the management of the bladder carcinoma were discussed. The results were as follows: 1. Of 54 patients, 34 patients were low stage(0-A) and low grade(1-2). 2. There is a significant correlation between tumor grade and SRCA test: Of 38 patients with low grade. 19 patients were SRCA positive, but of 16 patients with high grade. all were SRCA negative. 3. There is a significant correlation between tumor stage and SRCA test: Of 36 patients with low stage, 18 patients were SRCA positive, but of 18 patients with high stage(above B1), only one patient was SRCA positive. 4. There is a high possibility of false-negative results in detecting O(H) isoantigen: Of 36 patients with low stage, 6 patients were blood group 0 who were all SRCA negative. but 30 patients with other blood groups showed variable SRCA results. 5. There is a considerable correlation between tumor recurrence and SRCA result: Of 20 patients who were followed more than one year after initial TUR, 8 patients were SRCA positive, of these 4 patients were recurred, but 9 patients of 12 patients with SRCA negative were recurred.

Study on Serum and Urinary Uric Acid Level in Patients with Urinary Stone / 대한비뇨기과학회지

Currently, uric acid disorders, especially including hyperuricosuria, are thought to be important in the formation Of idiopathic calcium urolithiasis. Herein, we estimated the serum concentration and urinary excretion of uric acid in I22 stone-formers, comparing to those in 56 controls. Also, various theories about the pathogenesis of uric acid disorder and stone formation were discussed. The results were as follows: 1. Serum uric acid levels of stone-formers were significantly higher than those of controls, in total and female, but, not in male. 2. Urinary uric acid levels of stone-formers were significantly higher than those of controls in total, male and female. 3. Hyperuricemia was significantly more frequent for stone-formers in total, male and female. 4. Hyperuricosuria was significantly more frequent for stone-formers in total, but, not significantly more frequent for stone-formers in male and female. 5. The incidence of stone-formers, in whom hyperuricemia and hyperuricosuria were not present at the sometime, was significantly less than that Of controls. These results suggest the possibility that uric acid disorder may play some roles in the genesis of urinary stone.
