A Comparative Study of Catheter-tip Culture with Foley Catheters of Different Materials / 대한비뇨기과학회지

In the recent 2 years, we performed 116 Foley catheter-tip(48 cases of latex, 35 cases of 100% silicone, 33 cases of Silastic) cultures from the male patients who did not have lower urinary tract infection before catheterization. The following result were obtained: 1. The overall positive culture rate of rather-tip culture was 35.3%, and the positive culture rate of urine aspirated from proximal catheter wall just before removal of catheter was 20.6%. 2. The most common microorganism was E-coli in 29.3% and followed by Proteus spp. in 14.7%, Pseudomonas aeruginosa in 12.2%, Klebsiella pneumoniae in 9.8%, Staphylococcus aureus in 7.3%, Candida tropical in 7.3% in orders. 3. In comparison with duration of catheterization, the positive culture rates of catheter-tip of 3 different materials removed within one day were similarly low from 0 th 12%. However, the positive culture rate was much increased in latex-tip (70%) than silicone-tip (23%) and Silastic-tip (14.3%) which were removed between 2 to 4 days. More than 5 days of indwelling catheterization, the positive culture rates were latex-tip in 100%, silicone-tip in 47% and Silastic-tip in 57.1%.

A Case of Unilateral Multilocular Cystic Kidney / 대한비뇨기과학회지

Multilocular renal cyst is an uncommon entity of uncertain nature. By recent years only n few cases had reported in the literature. The difficulties encountered in distinguishing this entity from the Wilms' tumor indicate that this disease warrants great emphasis. We have experienced a case of unilateral multilocular cystic kidney treated with nephrectomy.

A Comparative Observation on Success Rates of Stone Dislodgers / 대한비뇨기과학회지

A comparative observation was done on 139 patients of the lower ureteral stone, those were applied cystoscopic manipulation with 3 different types of stone dislodger at the Department of Urology, Seoul Adventist Hospital, during the periods from Jan. 1982 to June 1985. During that periods, we applied end-loop catheter in 48 patients, blunt-tip Dormia basket in 38 patients. The results were as follows; 1. The success rate of passage of dislodger beyond the stone was the highest in filiform-tip Dormia basket (97.4%) and loop catheter was the lowest (8l.3%). 2. The success rate of the primary stone extraction with filiform-tip Dormia basket was the highest (86.8%). 3. Indwelling of the dislodger in the ureter loop catheter was the most successful method among them(62.5%). 4. Of the cases of passage beyond the stone, the success rates of the stone extraction were very high and similar in their results, as in 92.3% with loop catheter, in 90.9% with blunt-tip Dormia basket, in 91.9% with filiform-tip Dormia basket. 5. The overall success rate of stone extraction was 75.0% in loop catheter, 75.5% in blunt-tip Dormia basket 89.5% in filiform-tip Dormia basket.

Chemical Analysis of the Urinary Stones / 대한비뇨기과학회지

We have analyzed 100 urinary calculi by chemical analysis, which obtained from the patients admitted our department during the period from March, 1981 to February, 1983. The following results were obtained: 1. The results of chemical analysis of 100 urinary calculi revealed calcium oxalate phosphate in 43%, calcium oxalate in 19%, calcium phosphate in 15%, ammonium phosphate in 12%, carbonate calcium oxalate phosphate in 7%, uric acid in 2%, acid + calcium phosphate in 2%. 2. 40 of 100 patients with urinary stones showed bacteriuria and Staphylococcus epidermidis was the most frequent organism. 3. The causative diseases of the urinary stones were renal tuberculosis 4 cases, neurogenic bladder in 4 cases, urethral stricture in 3 cases, BPH in 1 case and hyperparathyroidism in 1 case. 4. The incidence of high urinary calcium amount was greater in lithiasis group(43%) than in control group(17%) The incidence of high urinary calcium amount in lithiasis group was as following order: calcium oxalate phosphate in 55.8%, calcium phosphate in 46.7%, calcium in 42.1% and ammonium phosphate in 28%.

A Case of Inverted Papilloma of Urinary Bladder / 대한비뇨기과학회지

Inverted papilloma of the urothelium is a rare, benign polypoid lesion which has typical histologic findings. Microscopically, a nonpapillary urothelium covers the surface from which cords of same epithelium invert and extend deep into the core in an anastomosing pattern, always maintaining its benign histological characteristic. Recently, we experienced a case of inverted papilloma of the bladder in 23-year-old male.

A Giant Hydronephrosis Associated with Staghorn Calculus / 대한비뇨기과학회지

One case of giant hydronephrosis associated with staghorn calculus was presented in 65 year old man. It`s containing fluid was about 4,000ml in amount. We reported this cases with a brief review of the literature.

A Case of Congenital Solitary Pelvic Kidney / 대한비뇨기과학회지

The pelvic kidney, which is located opposite the sacrum and below the aortic bifurcation is art ectopic renal mass with a congenitally short ureter and aberrant blood supply. The pelvic kidney may be assumed that any factors arresting the cranial migration of the ureteral buds. Genital anomalies are frequently associated in renal ectopia, which are affected on uterus and proximal vagina in female patient. We have experienced a case of congenital solitary pelvic kidney with amenorrhea in 21-year-old female patient.q

Yolk-sac Tumor of Testis in Male Infant with Pulmonary Metastasis: A Case Report / 대한비뇨기과학회지

Yolk-sac tumor in the testis is a very rare testicular tumor, most of which occurred in young children. Typical microscopic finding of yolk-sac tumor reveals perivascular mantles (Schiller-Duval body) with papillary structure. In the absence of distant metastasis, prognosis of yolk-sac tumor is known to be good. Recently. we experienced a case of yolk-sac tumor of the testis in 19 months male infant who had pulmonary metastasis with poor prognosis.

Clinical Observation on the Gonorrhea and Non-specific Urethritis / 대한비뇨기과학회지

During the period from Jan. 1978 to June 1978, clinical and laboratory observations were done on the 46 cases of gonorrhea and 40 cases of non-specific urethritis at random selection in the Department of Urology, Korea University Hospital. The following results were obtained: 1. The average age of the gonorrheal patients were 24 years old and 30 years in non-specific urethritis patients. 2. The main clinical symptoms of gonorrheal patients were profuse yellowish urethral discharge found in 91.3 % of cases and painful urination in 37 %. The symptoms of non-specific urethritis patients showed scanty urethral discharge in 525 % of cases and urethral discomfort in 25%. 3. The incubation period of gonorrheal cases was 3 to 7 days while in one-fourth of non-specific urethritis the period was shorter than 10 days. 4. In the past history 43.5 % of gonorrheal patients had V. D. and 62.5 % of non-specific urethritis patients had them. 5. In 20 cases ( 50%) of non-specific urethritis had positive shred culture with no evidence of positive findings in urinalysis or in Gram stain of urine sediment. 6. In 31 cases(77.5%) of positive shred cultures, staphy lococcus albus were grown in 12 cases, diphtheroid in 10 cases, mixed growth of staphylococcus albus and diphtheroid in 5 cases. Antimicrobial sensitivity test with Gram(+) cocci obtained from 19 cases of nonspecific urethritis showed highly sensitive resultes to hentamicin, lincomycin, carbenicillin, novobiocin and highly resistant reactions to oxytetracycline. 7. 82.6% of cases of gonococcal infection were cultured on the Thayer-Martin medium and antimicrobial sensitivity test was done with these colonies by disc diffusion method. Penicillin and its derivatives were highly sensitive, other antibiotics such as erythromycin, oxytetracycline, chloramphenicol and gentamicin were also sensitive.

Urine AFB was found in 26 cases (52%). 10. 18 cases of AFB culture was done with drug sensitivity test, which showed that INH was the most sensitive drug, but PAS and streptomycine were sensitive in high concentration of the drugs only. 11. On the urogram, non-visualization of the kidney was found in 20 cases and delayed visualization in 15 cases while abnormal ureteral findings noted in 18 cases. 12. Nephrectomy was performed in 23 cases out of 31 operated cases and nephrostomy was done in 7 cases. 13. Histopathological findings of 23 nephrectomized kidneys disclosed parenchymal tuberculous nodules in all cases and severely atrophic changes in 3 cases.
