Transperineal urethroplasty using the perineal-scrotal flap is recommended when an end-to-end anastomosis is not feasible, either because of a long stricture or severe scar secondary to previous operative failures. This technique seems to give better exposure than inlaid scrotal grafts and requires no special instruments other than the posterior urethral needles. A clinical observation was made on 10 patients of posterior urethral stricture who performed transperineal urethroplasty in the Department of Urology, Kangnam Sacred Heart Hospital, Hallym Medical College during the period from January. 1980 to January, l985. Among these 10 patients, 8 underwent by Blandy`s exteriorization operation and 2 underwent by intussusception into the prostatic urethra. The results in these cases. 6 had favorable results without voiding problems and 2 needed periodic urethral dilatation due to restricture. Impotence and incontinence was developed in 2 cases each other.

In order to observe the protein compositions of soluble extracts of P. westermani, and their changes during early developmental stages, the crude saline extracts of 4, 6, 8, 10 and 12 week-old worms which were harvested from experimentally infected dogs were analysed by disc-PAGE. The results were as follows: A total of 15 bands were identified from electrophoregrams of respective developmental stages. Of them, 5 bands were recognized throughout the developmental stages. The number and protein amount of identified bands changed according to the worm development from 4 weeks to 12 weeks. However, the banding patterns of 4 and 6 week-old worms and 8 and 10 week-old worms were similar each other. Of 15 identified bands, band 1 was recognized only in 12 week-old worms whereas bands 3, 4, 8, 9, 10, 11 and 15 gradually lowered their amount according to development to disappear in 12 week-old. In addition, band 5 became a major band in 12 week-old while band 6 turned to a minor band at tha same age. The possible relations of changing patterns of protein bands with worm development were discussed.
