Intrascrotal Lymphangioma 2 Cases / 대한비뇨기과학회지

Intrascrotal lymphangioma is a rare benign lesion of uncertain etiology. A 2-year-old male and a 3-year-old male presented with painful swelling of the right scrotum. After sonographic examination of scrotums, both cases were explored and found to have cystic scrotal masses separated from testes and epididymies. Histopathologic study of the resected specimens confirmed intrascrotal lymphangiomas.

The effects of Intraurethral Stent (Intraurethral Cath) for the Treatment of Benign Prostatic Hypertrophy / 대한비뇨기과학회지

Transurethral resection of Prostate(TURP) is the current optimal therapy for benign prostatic hypertrophy. But in some cases of BPH patients, TURP cannot be performed because the patients have medical disorders not to be operated. Thus several alternatives have been used in the management of BPH patients, especially who had anesthetic contraindications to an operation. We experienced 12 cases of BPH patients applied with Intraurethral Cath(IUC) from April 1991 to September 1995. Eleven patients became able to void after IUC insertion. The maximal flow rates were 5.1 to 15.7 ml/sec and average value was 11.8 ml/sec. Almost all patients showed irritative voiding symptoms such as urgency, urge incontinence, frequency, and dysuria at first. In 7 patients, these symptoms disappeared spontaneously within 2 to 5 days and oxybutynin chloride was used orally in 2 patients. Suprapubic cystostomy was done in three patients because two patients had severe irritative voiding symptoms and one patient had persistent urinary retention. The stent was changed every 3 to 6 months. Stone formation around the device was noted in 2 patients and migration of device into the bladder was found in 2 patients. In 4 patients, TURP was performed when the patient's condition improved enough to be operated under epidural anesthesia. In conclusion, the use of IUC is thought to be a valid, cost effective and safe alternative to TURP in the treatment of highly operative risk patients with benign prostatic hypertrophy.

The clinical value of IVP in BPH / 대한비뇨기과학회지

Routine use of the IVP in preoperative evaluation of patients with obstructive bladder outlet symptoms has been questioned on the basis of the chance of incidental finding in the upper tract and the implication of such findings to management. We studied 220 patients who underwent intravenous pyelography before prostatectomy at Department of Urology, Sanggye Paik Hospital from Oct. 1989 to Jun 1992. Of 220 patients, 183( 83.2% ) showed normal upper tract with cystogram compatible with benign prostatic hyperplasia. Abnormalities were found in 37( 16.8% ) patients but treatment plan was altered in only 5(2.25% ) cases. Most of these abnormalities could be detected on KUB or cystoscopy. Only one(0.45% ) malignancy would have been missed without routine IVP. We conclude that IVP in our opinion should not be performed as a routine procedure in patients with benign prostatic hypertrophy, but only in selected cases.

Solitary Renal Metastasis of Adenoid Cystic Carcinoma of Minor Salivary Gland: A Case Report / 대한비뇨기과학회지

Adenoid cystic carcinoma (ACC) is a malignant epithelial neoplasm of typical histologic features and biologic behavior. It most often arises in the major and minor salivary glands of the head and neck, but has been noted in the trachea, lung, breast and elsewhere. Its biologic behavior is characterized by slow but aggressive growth with multiple local recurrences and frequent distant metastases, often over a period of years. Lung is the most common site of metastasis followed by bone, brain and liver. Herein, we report a solitary renal metastasis of ACC which occurred 8 years after successful extirpation of the primary tumor in minor salivary gland.

The Effect of Experimental Varicocele on Fertility in Adolescent Rats / 대한비뇨기과학회지

Varicocele is considered as one of common etiology for subfertility in men and recently it is acknowledged that varicocele first developed in puberty exert more severe damage to testicular structure than that in adulthood, but its ultimate effect on the fertility is not well known. We used animal model to compare the effect of varicocele on the fertility and histology in the adolescent with that in adulthood. Sprague-Dawley rats were treated to create varicocele at 7 weeks and 12 weeks of age by partial ligation of left renal vein. After 4 weeks of sexual maturation period passed, each male rat was mated with two female rats for 21days and then scarified to examine the testicular volume loss and histologic change. All female rats were also sacrificed for the evaluation of pregnancy rate, litter side and fetal weight. Pregnancy rate in adolescent rats were 47.1% and there was significant difference in fertility between control rats and rats with varicocele. Interestingly the impregnating ability of adolescent rats was correlated with the mean diameter of seminiferous tubules of both testicles. ipsilateral testicular volume loss and histologic changes were more severe in adolescent rats than in adult rate. In summary, varicocele created in adolescent Sprague-Dawley rats is considered to be implicated. in their adulthood fertility, probably due to its more severe damage to testicular volume and histologic change(especially tubular narrowing) than in adult rats.
