We administered intracavernous injections of 20 micrograms. prostaglandin E1 to 135 patients with impotence, and evaluated the effects and side effects. Among 135 patients who underwent intracavernous injection of prostaglandin E1 complete erection was observed in 83 (62 per cent), while incomplete erection was noted in 33 (24 per cent). In both groups the erection was sufficient for sexual intercourse. Tumescence without rigidity was noted in 12 patients and no response was obtained in 7. Poor response was seen frequently in patients with disorders of the vascular system and/or damage to the cavernous body of the penis. Priapism after the injection was not observed. Moreover, we never observed any other severe side effects. Intracavernous injection of prostaglandin E1 could be applicable to the therapy of impotence, especially that due to neurogenic disturbance. Since prostaglandin E1 acts quickly and loses its validity rapidly it is considered to be a more suitable agent than other vasoactive drugs.
From 1979 to 1983, surgical reconstruction of the buried penis was performed on 16 boys. They have been followed up for at least 5 years. In 15 boys, satisfactory appearance of the penis was gotten after the operation. In this paper, we introduced our surgical technique and reviewed the records.
A 60-year-old man visited our hospital with complaints of micturition pain and interruption of urinary stream. X-ray examinations were performed, showing no bladder and urethral stone. However, KUB revealed bilateral multiple renal stones. Excretory urography showed a horseshoe kidney and a concentration of the contrast medium in the ectatic tubules at the pyramidal apices. Calculi were also located in these ectatic tubules. Thus, we considered that this was a very rare case of medullary sponge disease associated with horseshoe kidney. So far there has been no case report of medullary sponge disease with horseshoe kidney in our country.
A case of ureteral obstruction secondary to diverticulitis is described. The patient had a 2-month history of lower left quadrant pain before an operation. As an intravenous pyelogram showed persistent hydronephrosis, an operation was performed. At the operation, a fibrotic mass which encased the left ureter and sigmoid colon was found. Ureterolysis and segmental sigmoidectomy were carried out. The pathological specimen showed two diverticula and subserosal cicatrization.
The concentration of transferrin in seminal plasma and serum levels of LH, FSH, testosterone, and prolactin were measured in 94 male patients attending our infertility clinic. The concentration of transferrin in patients with azoospermia was lowest among azoospermia, oligozoospermia, and normozoospermia groups. There was significant positive correlation between the concentration of transferrin in seminal plasma and sperm density. However, seminal plasma transferrin was inversely correlated with serum levels of LH, FSH, and prolactin, respectively. It is suggested that transferrin in seminal plasma contributes to the activation of seminiferous tubules and can be used as a reliable index of Sertoli cell function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
