A Case of Prostatic Adenocarcinoma Confirmed by Immunoperoxidase Technique / 대한비뇨기과학회지

Recently, the use of immunoperoxidase technique for the location of prostatic acid phosphatase is well established. We experienced 67 year-old male patient who taken TUR due to mass on bladder neck. Previously he had received Rt. radical nephrectomy due to renal cell carcinoma 6 years ago and TUR due to metastatic urethral adenocarcinoma from renal cell carcinoma origin 3 years ago. The Pathologic report represented that the mass was malignant adenocarcinoma. To confirm the origin of adenocarcinoma, we performed immunoperoxidase technique and the adenocarcinoma was originated from the prostate.

Echinococcal Cyst: A Case Report / 대한비뇨기과학회지

Echinococcal cyst is a rare disease in Korea. A 33 year old man who had lower abdominal discomfort for 4 months, and multiple cysts in intraperitoneal and retroperitoneal cavity on abdominal CT. scan. On abdominal exploration, the multiple were diagnosed for Echinococcal cyst. Thin case is the first documented case of multiple Echinococcal cysts among Koreans reported in the literature.

Clinical Observations on Acute Scrotum / 대한비뇨기과학회지

Acute scrotum is any pathologic condition of the scrotum or intrascrotal contents that requires emergency medical or surgical management. Management of each disease entity is different, but the differential diagnosis is very difficult. So many testes had been lost due to delay of the adequate surgery and unnecessary explorations had been taken under the misdiagnosis. Clinical observations were carried out on 59 patients with acute scrotum admitted to the department of urology, Ewha Womans University Hospital during 10 years from April, 1976 to March, 1986. There were 36 patients with acute epididymitis, 6 spermatic cord torsion and 17 scrotal trauma, the mean age was 32.6 year old in acute epididymitis, 12.8 spermatic cord torsion and 23.5 scrotal trauma. Symptoms and signs showed no significant difference from each disease entity, but Prehn`s sign was somewhat useful to differentiate each one. In half patients with spermatic cord torsion that had arrived to the hospital within 24 hours from onset of symptom, the testes could be saved. Testicular scan with 99mTc-perte- chnetate was performed in 14 patients and the diagnostic accuracy was 93%, 21 patients with acute epididymitis had urinary tract infection and spermatic cord torsion occurred in 2 patients with cryptorchidism.

Application of Nd-YAG Lasers in Patients with Bladder Tumor / 대한비뇨기과학회지

Advances in laser technology have resulted in the creation of a new field of medical therapy. By virtue of the hyperdermic effects that can occur when intense energy of laser light is absorbed and transformed into heat, some lasers can be used to destroy tissue by vaporization or coagulation. The technology to allow extensive use in urology has only been recently perfected with the development of flexible light guides adaptable to standard urologic instruments. The Nd_YAG lasers can be attached to these urologic instruments and transmit through the water or the urine, so it has been prevailed in urologic disease, especially bladder tumor. We used the Nd_YAG lasers for the treatment of 25 patients with bladder tumor that admitted to the department of urology, Ewha Womans University Hospital during the period from October, l984 to July, 1986. The Nd_YAG lasers could be attached to the standard urologic instruments easily, so its use was very convenient and almost all portion of bladder wall could be irradiated. Intraoperative and postoperative bleeding was absent and indwelling of catheter wasn`t needed. During operation the obturator nerve reflex didn`t occur and the Jepth of coagulation could be controlled, so the risk of vesical perforation was almost nil. One year recurrence rate and progression rate to invasive tumor of 21 superficial bladder tumor patients was 28.6% and 4.8%, local recurrence didn`t occur in all patients. The main disadvantage of lasers was the incapability to get the pathologic specimen for staging and grading of tumor. Although laser therapy alone cannot obtain tissue specimen, it has various advantages and concomitant use with TUR increases the effectiveness of tumor therapy. So the lasers will act as an important role in the treatment of bladder tumor.

Leiomyosarcoma of the Spermatic Cord: Case Report / 대한비뇨기과학회지

We report a case of leiomyosarcoma of the spermatic cord with the review of literatures. To our knowledge, this is the first case to be reported in Korea.
