Hemodialysis using Kiil type artificial kidney was performed on two cases of acute renal failure and a case of chronic renal failure and the following results were obtained: 1. A case of acute renal failure recovered from her deteriorated renal function following four consecutive hemodialyses and another following a single hemodialysis of six hours. 2. A case of chronic renal failure is now stabilized clinically and maintained on ambulatory intermittent long-term hemodialysis.

The incidence of giant condyloma acuminata of the penis is extremely rare. Although they are considered clinically malignant, the real possibility of malignant changes from them are controversial even among the investigators but cannot be entirely overlooked. Therefore, attention must be focused on this fact, in our conclusion. Two cases of malignancy of the penis which have apparently been transformed from giant condyloma acuminata of the penis are herein presented with review of related literatures. Case I: Sixty nine year old male patient complained of a fungating mass on the sulcus coronaris of the penis with ulceration and bleeding from the mass. Biopsy confirmed giant condyloma acuminata and subsequently circumcision and electrocoagulation were performed. Pathological specimen taken after 4 months because of the recurrence of the mass on the same region showed squamous cell carcinoma of the penis and amputation of penis was performed. Case II: Sixty eight old male patient complained of a growing mass and pain on glans penis. This patient also underwent circumcision and electrocoagulation according to the biopsy finding of giant condyloma acuminata. But 1 year later with recurrence of the mass on the same region, the pathological finding revealed squamous cell carcinoma of penis.

A clinical evaluation has been undertaken of 41 patients with urethral stricture who have been treated with visual urethrotomy in the Department of Urology, Seoul National University Hospital during 3 years periods from 1983 to 1985. The over all success rate was 54%. The results were unrelated to the sites of the lesion, the causes of the stricture and the durations of the catheter drainage. However, the results of the obliterated strictures (12.5%) are more poor than the non-obliterated strictures (64%), and patients with nonobliterated stricture less than 2cm long had the best results (22%). The overall morbidity rate was 20%, six cases of false way, one case of incontinence, one case of penile hematoma. Twenty seven cases were followed up over 6 months and its success rate showed 44.4%.

Fourteen total cystectomy specimens with primary carcinoma of urinary bladder were investigated to illustrate the overall prevalence and nature of mucosal changes adjacent to the overt carcinoma and to clarify the distribution pattern and extent of carcinoma in situ in regard with multiplicity, histological type and depth of invasion of the macroscopically visible tumor mass. Of 14 cases subjected to this study were 12 cases of transitional cell carcinoma of varying degree of differentiation and invasion, one adenocarcinoma, and the another one with no grossly detectable tumor but history of previous cystoscopic removal of papillary transitional cell carcinoma. Each specimen was processed by a histotopographic technique developed by authors, an easy access to reconstruct the mucosal changes using reconstruction paper. For the histological grading and staging of the overt carcinomas, Ash's and Collins' classifications were applied, respectively. Carcinoma in situ (CIS) was found in 10 out of 11 cases with overt urothelial carcinoma of urinary bladder and one case with no grossly visible neoplasm, in which cystoscopic removal of papillary carcinoma was carried out previously. Distribution pattern of CIS was mostly circular (group I) or arborizing (group II) , located around the overt carcinoma within 0.5 to 2.0cm., but not beyond 3.0cm. from its margin. Correlation between multiplicity of overt carcinomas and presence of CIS was evident together with irregularity of its distribution, but no significance was found with gross appearance, histological grading or with staging.

Thirteen patients with contracted bladder due to tuberculosis who underwent surgical intervention were evaluated The most common agonizing symptom was frequency. Surgical management included augmentation cystoplasty in 8 patients and urinary diversion in 5 patients. In augmentation cystoplasty, the overall success rate of 87.5 % has been achieved in view of relief of symptom, improvement of bladder capacity and preservation of renal function. For the success of augmentation cystoplasty, creatinine clearance higher than 30 ml/min., no abnormality in selected intestinal segment, absence of uninhibited detrusor contraction or detrusor-sphincter-dyssynergia and no bladder outlet obstruction are inevitable. As an alternative, urinary diversion should be considered only in cases of severely deteriorated renal function, severely decreased bladder capacity, bladder outlet obstruction, neurogenic bladder and inapplicability of augmentation cystoplasty.

We report a case of pseudosarcomatous variant of transitional cell carcinoma of the renal pelvis which showed grossly and microscopically the distinct biphasic growth patterns. Grossly, most part of the tumor showed solid growth protruding into the renal pelvic cavity as well as infiltrating into the parenchyma of lower pole. The overlying pelvic mucosa was replaced by a diffuse, papillary transitional cell carcinoma, and the solid mass was composed of pleomorphic spindle cell sarcomatoid component with frequent myxoid change and a few foci of osteoid deposit. Ultrastructural study of the spindle cells revealed epithelial differentiation featured with rich cytoplasmic organelles, basal lamina and basement membrane-like structures, although immunohistochemistry failed to detect epithelial differentiation.

Palliative open nephrostomy was done on 50 cases with advanced pelvic malignancy and benign conditions in the Department of Urology, Seoul National University Hospital during the period of March, 1979 to July, 1982. The results were as follows: 1. 20.5% (9/44) of our patients died without being discharged from the hospital after nephrostomy. 2. In advanced pelvic malignancy, only 52.6% of patients alive at 3 months and only 26.3% alive 6 months. 3. In advanced pelvic malignancy, the post-nephrostomy complication was 46.7% and the most common complication was various urinary problems. 4. The cause of death was multifactorical and impossible to define precisely. The nephrostomy complications were at least in part contributory to the deaths. 5. The terminal malignancy patients who might not expected to live six months and to lead a useful, relatively comfortable life outside the hospital after treatment could not have benefited from nephrostomy. Unavoidable cases, we recommended percutaneous nephrostomy and passage of ureteral catheters instead of open nephrostomy.

We analyzed the composition of urinary stones using chemical analysis method. From 1985 to 1995, 495 urinary calculi were eligible for stone analysis. Forty six per cent of the stones were composed of single chemical component, and pure calcium oxalate stone was the most common type of the stones consisting 34.9% of all stones, followed by 23.8% of mixture of calcium oxalate and calcium phosphate, and 92.7% of the stones had calcium component. Calcium oxalate crystal was found in 82.6% of the stones, calcium phosphate in 50.5%, ammonium magnesium phosphate in 26.7%, uric acid in 11.3% and cystine in 0.4%. Nation-wide extension of this study using chemical analysis will be mandatory for a proper assessment of the stone composition of Koreans and for planning of the proper management strategies for urinary stones in Korea.

A study was done to evaluate the diagnostic value of ultrasonography on acute scrotum patients. During the last three years, 25 patients were managed at Cheju Medical Center, eight of them were testicular torsion patients including one cryptorchid testicular torsion. one torsion of appendix testis, 11 acute epididymitis and 5 testicular rupture due to blunt scrotal trauma. Ultrasonography revealed enlarged testis and epididymis in all of the 8 testicular torsion patients and 7 of them showed inhomogeneously decreased echogenecity of the testis and epididymis. All acute epididymitis patients showed enlargement of the epididymis, and inhomogeneously decreased echogenecity was found in 8 of them. But testicular echogenecity was normal in all of the acute epididymitis patients and enlargement of the testis was found in two. All of the 5 testicular rupture patients showed irregular hypoechoic portions in the testicle and distorted testicular morphology, and linear fracture lines of the testis were found in two. We could suggest that scrotal ultrasonography is useful for the early differential diagnosis of the acute scrotum, especially when scrotal radioisotope scan is not available.
