The tension-free tape was significantly superior to the pubovaginal sling in terms of operation time, postoperative pain, and hospital charges, but not in cure rates. A longer follow up with a larger sample size is necessary to draw definite conclusions.

We report a patient whose irritable bladder symptoms following Bacillus Calmette Guerin (BCG) instillation were satisfactorily treated by steroid administration. A 59-year-old male had undergone transurethral resection for the bladder carcinoma recurred three times. The histopathological examination revealed the tumor as transitional cell carcinoma, G1 to G2, and pTa. Subsequently an instillation of 80 mg BCG into the bladder was planned 8 times every 7 days. After the 5th instillation he presented with gross hematuria, painful micturition, pollakisuria, urgency and reduced bladder capacity of 15 ml. The dose was reduced to 40 mg and another 3 instillations were accomplished. Since conventional treatments of anti-cholinergics, analgesics and epidural anesthesia were of little help for the subjective symptoms, he was put on the steroid pulse therapy 2 weeks after completion of the BCG regimen. The treatment gradually improved the subjective symptoms and increased the bladder capacity up to 160 ml. In conclusion, we believe that the steroid pulse therapy deserves considering in the early stage of irritable bladder symptoms following BCG instillation.

It was found that urolithiasis was 10 times more prevalent in those patients operated on with enterocystoplasty than those without bladder augmentation and that intermittent clean catheterization and regular bladder irrigation were of necessity to prevent urolithiasis for those having enterocystoplasty.

The dietary folate and serum folate concentrations averaged 293 micrograms/day and 8.1 ng/ml, respectively. The former is the first report based on the 5th standard table of food composition in Japan. Majority of pregnant women took less dietary folate than what recommended by the government. Those who are capable of becoming pregnant are recommended to consume much of the 3rd food group and those who are planning to become pregnant are recommended to take 400 micrograms of folic acid supplements from 4 weeks before to 12 weeks after conception.

A 72-year-old man referred our hospital with the chief complaint of macroscopic hematuria. He had undergone simple left nephrectomy for left renal stone when he was 27-years-old. His urine cytology showed class IIIb. They were 4 times. We performed random biopsy of the bladder and retrograde pyelography of the right But they were no positive findings for the cause of hematuria and for the existence of malignancy. After 2 months, he had macroscopic hematuria again. Cystoscopic re-examination revealed a fibrin out of the residual left ureteral orifice. Computed tomographic scan showed a perivesical mass. The diagnosis was the carcinoma of the ureteral stump. We performed ureterectomy. The pathological study revealed the undifferentiated carcinoma. This case is the first report of the undifferentiated carcinoma occurred on the residual ureteral stump in the Japanese literature.
