ABSTRACT
An experimental study in vitro using piezoelectric extracorporeal shock wave lithotriptor(EDAP LT-01) and urinary stones removed from the patients by surgical method has been performed. The purposes were 1) to correlate the stone components and sizes with the storage of complete fragmentation, 2) to examine the screening effect and 3) to observe the stone fracture mechanism in urinary stones. The following results were obtained. 1. Tribasic calcium phosphate stone, magnesium ammonium phosphate stone and uric acid stone fractured more easily than calcium oxalate stone. In the case of small stones(diameter 0.5 cm), all stones fractured at relatively low storage. Large stones (diameter 1.5 cm) fractured at high storage with wide variations according to components. 2. Magnesium ammonium phosphate stones tested to observe for screening effect showed that a high storage was needed for complete fragmentation(about 2 times) when the stone debris was not removed. 3. Urinary stones fractured first on the front surface. When the stones showed lamellae, which were separated first by shock wave, thereafter each lamella was broken.

An ectopic ureteral orifice inserts at a point other than the trigone of the bladder. Ectopic ureteral orifices in a girl commonly are associated with complete ureteral duplication comprises only 10 to 12 per cent of such patients. Continuous incontinence in a girl with an otherwise normal voiding pattern after toilet training is the classic sign of an ectopic ureteral orifice. Here, we report a 3-years-old girl who was admitted to our hospital due to continuous urinary incontinence and managed with the diagnosis of bilateral ectopic ureteral orifices associated with bilateral complete ureteral duplication.

Carcinoembryonic antigen(CEA) was measured in the serum and urine of 46 patients with bladder cancer and 15 patients with non-cancer disease as control group at the Paik Hospital. Pusan during the period from January, 1986 to June, 1988. The following results were obtained. 1. The upper limits of normal serum and urinary CEA levels in non tumor control group were 3.7 ng/ml and 2.3 ng/ml. Mean and positive rate of serum and urinary CEA levels in bladder cancer group were 4.40 ng/ml(37.0%) and 21.52ng/ml(65.2%). 2. Mean urinary CEA level was correlated significantly with the stage, grade and size of bladder cancer but no significance was seen in serum CEA. In the advanced cases(Stage C, D), serum CEA levels were elevated. 3. The diagnostic rate was not elevated in spite of urinary CEA determination combined with urinary cytology. After transurethral resection of cancer mass and radiation therapy, urinary CEA level decreased. As a result, serum and urinary CEA determinations in bladder cancer have no diagnostic value, but it will be useful in the study of the extent of cancer, effect of therapy, recurrence and prognosis.

The massively dilated ureter is one of major therapeutic challenges that face the urologists. The goals of reconstructive procedures are the elimination of residual urine, effective ureteral peristalsis, efficient and/or urgent drainage. 6 cases of primary obstructive megaureter were presented with review of literatures. The results obtained were as follows ; 1. 6 cases were divided into 2 groups according to etiology with 4 adynamic segments and 2 intrinsic stenosis. 2. The underlying histopathologic features included 1 submucosal inflammation,2 submucosal fibrosis with inflammation and 2 submucosal fibrosis. 3. 5 cases were treated with Hendren's technique and 1 case treated by ureteral meatotomy. 4. All cases showed obvious improvement of upper tract without complication during follow-up period from 5 to 26 months.

The leiomyosarcoma of the spermatic cord is a rare malignant tumor which constitutes approximately about 10% of sarcomas of the spermatic cord and tunics. In Korea, only one case has been reported. Because the cases presented are too small to be mentioned, the efficacy of retroperitoneal lymph node dissection, radiotherapy and chemotherapy are not settled. The standard therapy for leiomyosarcoma has been radical orchiectomy with high ligation of the spermatic cord. Here, we report a case of the leiomyosarcoma of the spermatic cord and review the role of retroperitoneal lymph node dissection.

We studied 16 male patients complaining of impotence after trauma. Underlying causes of injury were posterior urethral injury (9 patients), pevic bone fracture (3 patients), perineal burn (2 patients), penile fracture (1 patient) and spinal cord injury (1 patient). Rigiscan was used for diagnostic test and compared with other erectile function tests (Papaverine injection test, Snap Gauge test, PBI(penile brachial index) and PDI (penile digital index) test, AVS (audiovisual stimulation) and Erectiometer tests. The results obtained were as follows: 1. In 9 patients shown normal rigiscan, the number of erection was 1.56+/-0.87 times per night, duration was 14.2+/-7.54 minutes at tip and 20.1+/-9.42 minutes at base, tumescence change was 2.30+/-1.64 cm at tip and 3.40+/-0.73 cm at base, rigidity was 66.28+/-13.33% at tip and 78.86+/-21.43% at base. 2. Among 9 patients shown normal rigiscan, 8 patients showed partial to full rigid erection in intracavernous Papaverine injection test. 3. In 7 patients shown abnormal rigiscan, the findings of Snap Gauge test, AVS test and Erectiometer test showed slight to absent responses, but 9 patients shown normal rigiscan presented variable findings. 4. 13 patients with PBI > or=0.75 and 15 patients with PDI > or =0.77 showed normal rigiscan. but patients shown abnormal rigiscan presented variable findings of PBI and PDI tests. Conclusively, rigiscan and intracavernous Papaverine injection test showed high corresponding rate, but other erectile function tests presented variable findings in patients complaining of impotence after trauma.

The lymphangioma of the scrotum and retroperitoneum is a rare benign tumor secondary to congenital abnormal development of the local lymphatic communications, and about thirty cases have been reported in the literature. The majority of the patients are observed in the third to fifth decades, but this neoplasm has been reported even in the newborn. The frequent site of the lymphangioma occurs in the neck and axilla. Other sites are uncommon and one of the least frequent site is the scrotum and retroperitoneum. Treatment is complete surgical excision, unless completely removed, recurrences are common. Here, we report a case of cystic lymphangioma of the scrotum and retroperitoneum of a 26-years-old man.

We report a case of retroperitoneal fibrosis of uncertain cause, in which surgical ureterolysis could be established. The initial symptoms of patient were right flank dull pain and low abdominal discomfortness. At the multiple biopsy during ureterolysis, no neoplastic cell could be seen. After one month of discharge, advanced stomach cancer was found during evaluation of dysphasia and indigestion which appeared after discharge. So, the patient was placed on the conservative treatment after ureterolysis due to advanced stomach cancer.

Congenital renal arteriovenous malformation is a rare lesion. Nephrectomy or partial nephrectomy is a well-known treatment and as alternative method, transcatheter embolization therapy has been developed. We report a case of congenital arteriovenous malformation manifested by intermittent right flank pain and gross hematuria with blood clots, cured by means of transcatheter embolization therapy during angiographic study with polyvinyl alcohol foam (IVALON).

The renal oncocytoma is a rare benign tumor arising from the proximal tubular cells and has recently become a recognized clinical and pathologic entity. The feature of this tumor includes the tendency to (1) be incidental finding, (2) be large in size, (3) have well defined borders, (4) exhibit benign clinical behaviors. Here, we report a case of renal oncocytoma which was found incidentally due to pelvic inflammatory disease of a 37-years-old woman, who was treated with the radical nephrectomy.

The vaginal stone associated with vesico-vaginal fistula is quite rare and its cause, frequency, composition and others are poorly understood. We report a case of huge vaginal stone associated with vesico-vaginal fistula in 57 years old woman. considering of the possible causes of stone formation in the vagina and its composition, prevention, treatment complication and others. A stone, 6 x 7 x 5cm in size, was removed by litholapaxy. The stone was composed of uric acid, magnesium ammonium phosphate and carbonate appetite.
