When the bladder is obstructed by BPH, the contractile strength is increased to empty completely. If the obstruction is too severe to overcome by detrusor contraction, there will be residual urine. If detrusor is still compensated there will be no postoperative residual urine. But if detrusor is decompensated with "fading contraction" there will be postoperative residual urine. So the measuring of detrusor contractile strength is a very important test to predict the postoperative residual urine. We calculated the mechanical power generated per unit area of the detrusor surface(WF; Watts factor) to measure the detrusor contractile strength in 14 BPH patients with more than 100ml of residual urine preoperatively and compared the amount of preoperative residual urine with postoperative residual urine to evaluate the diagnostic value of WF in predicting the absence or presence of residual urine postoperatively. The WF in each 3 patients whose detrusor contractile strength seemed to be decreased with more than 50 ml of postoperative residual urine was less than 4W/m2, that was decreased than normal(4-11W/m2). In contrast, the WF .in each 11 patients whose detrusor contractile strength seemed to be normal or increased with less than 50ml of postoperative residual urine was more than 4W/m2, that was normal or increased. There was no significant difference in the amount of preoperative residual urine between both group of patients(p=0.2253, Wilcoxon rank sum test). There was no statistically significant relationship between the WF and the amount of preoperative residual urine in both group of patients(r =-0.028, p=0.92). In conclusion, WF measurement was a useful test in checking the detrusor contractile strength to predict the absence or presence of postoperative residual urine in patients with more than 100ml of residual urine.

Torsion of the appendix testis ranks second in causes of acute scrotal swelling in children Prompt surgical exploration in children with torsion of the appendix testis is necessary if scrotal swelling obscures diagnosis or induces persistent scrotal pain. Exploration of both testes at the first operation adds little trouble to the operation and eliminates the possibility of Further torsion.

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.

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.

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.

Mucinous adenocarcinoma of the renal pelvis is a extremely rare disease and reported less than 50 cases in literature. This tumor is known to be commonly associated with renal stone, hydronephrosis and pyelonephritis. We report a case of mucinous adenocarcinoma of the renal pelvis in hydronephrotic kidney with multiple renal stones.

One thousand one hundred forty nine (1149) young women, 13-21 years of age, were examined by urinalysis and bacteriologic methods for the frequency and natural course of asymptomatic bacteriuria. Five percent (58/1149) of the women were found to have a significant bacteriuria, of which 58.6% (34/58) had a transient colonization in the urinary tract and another 41.4 % had a persistent bacteriuria. 66.7% (16/24) of recurrent bacteriuric subjects had gram negative rod bacilli. In 8.6%(5/58) of asymptomatic bacteriuric subjects, symptomatic urinary tract infection developed within 6 months. An incidence of pyuria in asymptomatic urinary tract infection is 80%, but a sensitivity of pyuria to bacteriuria was low in asymptomatic urinary tract infection. A predictive value for detection of asymptomatic bacteriuria by pyuria was 19%. With urine collection by urethral catheterization a chance of contamination can be diminished, but may not be eliminated a chance of contamination from urethral mucosa. Randomized double blind study showed that asymptomatic bacteriuria can be effectively controlled by daily single dose of trimethoprim sufamethoxazole for five days.

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.

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.
