A clinical evaluation was made on 191 patients with urethral rupture and stricture, who had been admitted to the department of Urology during l3 years from l972 to 1984. We have tried the various methods in management of urethral rupture and stricture, such as 1) simple traction by balloon catheter 2) end-to-end anastomosis 3) perineal traction on the prostate 4) immediate cystostomy, and delayed urethroplasty in urethral rupture; 5) urethral dilatation 6) internal urethrotonry 7) end-to-end anastomosis 8) pull-through urethroplasty 9) transpubic urethroplasty 1O) scrotal inlay urethroplasty 11) perineal skin flap urethroplasty in urethral stricture. Especially, we have compared the primary realignment of urethral rupture with delayed urethroplasty Primary realignment with perineal traction on the prostate was most excellent in management of complete posterior urethral rupture, which had a low morbidity, complication, and cost. Immediate cystostomy, and delayed end-to-end anastomosis was good in management of complete anterior urethral rupture. We thought that the difference of result after primary. realignment or delayed urethroplasty of urethral rupture did not depend upon the alternative of them but the degree of urethral injury, surgeon's skill and the adequate application of them according to the state of patients at the time of urethral injury.

Continuous bladder irrigation with 1% alum solution was performed in 10 patients with various lesions in whom massive bladder hemorrhage persisted despite evacuation of clots and normal saline irrigation. Hematuria ceased promptly in all patients without any complication. So, we report them with the literature review.

Unilateral spermatic cord torsion has been shown to cause damage to the contralateral testis in humans and animal models. In the present paper, we have examined contralateral testes of prepubertal Sprague-Dawley rats 14 days after 720 torsion to determine the effect of scrotal surgery versus abdominal approach and to determine the effect of therapeutic orchiectomy versus detorsion. Torsion periods were 2. 6 and 24 hours. Histologic examinations of contralateral testis at the end of the experiment demonstrate that all rats of both the orchiectomy and detorsion groups had a significantly reduced mean seminiferous tubular diameter compared to controls (p<0.001). But the groups of abdominal approach had a smaller reduced mean seminiferous tubu1ar diameter than the groups of scrotal approach. These results indicate that these contralateral alterations seem to be caused by generalized perineal inflammatory responses as well as immunologic responses.

In 1923 Brettauer and Rubin reported that eight cases were accompanied with hydroureter and hydronephrosis among 10 patients who were suffering from prolapse of Uterus. And Wallingford, in 1939, investigated six cases of the prolapse and one of them died of Uremia resulting from severe renal damage. A suggestion, now widely believed, is that if the prolapse is neglected for a long time without medical treatment, the hydroureter and the hydronephrosis may develop frequently, because of angulating the ureters as they pass under the uterine arteries. Although Prolapse of the uterus induces the damage to the urinary tract, little attention has been paid for the urological study. The author has been studied an advanced hydronephrosis and hydroureter resulted from prolapse of uterus itself. Follow-up study for six weeks after total hysterectomy showed a great deal of improvement in renal function and NPN.

Prepubertal male Sparague-Dawley rats were used to investigate the effects of unilateral testicular torsion on the contralateral testicular histology. All rats were divided into eight experimental group (5 animals each), one of which was used for experimental control (sham operation). We have examined contralateral testes to determine the effect of therapeutic orchiectomy or detorsion after active physical 720' torsion (six hrs., twelve hrs., twenty four hrs.) through hemi-scrotal incision, and the effect of torsion only for two weeks. The contralateral testes demonstrated significant decreased weights variously and smaller seminiferous tubular diameter in both the orchiectomy and detorsion groups compared to the torsion only group, and there was marked contralateral testicular alterations in the torsion only group compared to the control group. These studies indicate that testicular torsion will cause contralateral testicular damage, and these contralateral alterations may be caused by generalized perineal inflammatory responses rather than immunologic phenomenon.

A series of 57 infants and children presenting with palpable abdominal masses which performed surgery from Jan. 1. 1972 to Dec. 31. 1978 has been reviewed. Masses such as distended bladder, abdominal distension, intussusception, intestinal obstruction, abscess, hematoma, as well as hepatospleaomegaly which not performed a surgical operation, were not included. There were 29 children with non-urological conditions, and 28 with urological lesions. The study was limited to the latter group. The groupings by age at presentation and type of urologic lesion enable us to make certain genera statements. About one-half of surgical abdominal masses were of urologic origin, and about one-third were renal origin. Since legions of renal origin are the predominant cause of abdominal masses in infants and children, an I. V. P. and other urological examination should be obtained as soon as possible on all children patients with abdominal masses.

Renal oncocytoma has been recently defined histopathologically but many controversies have arised about its origin and differential diagnosis. Until the present time nearly all renal oncocytoma were considered to be benign nature, but rare cases have been reported to be metastasized. We reported a case of renal oncocytoma and synchronous contralateral renal cell carcinoma treated by radical nephrectomy on one side and enucleation on the other side.

The incidence of testicular rupture by blunt trauma has been considered rare. But if testicular rupture has developed, the diagnosis of which is difficult. In the 50 cases of scrotal trauma patients, we investigated in the frequency of testicular rupture and early exploration in comparison with delayed exploration. Then the incidence of testicular rupture was in 46.1% of the cases of exploration, and early exploration of for scrotal trauma has resulted in higher testicular salvage rate than delayed exploration.
