The prognostic factors influencing the recurrence rate of superficial bladder cancer / 대한비뇨기과학회지

The high incidence or recurrent superficial bladder tumors (stage T1) after initial management presents a major therapeutic challenge. In order to define better the most important prognostic factors that influence the recurrence rate of these tumors, a retrospective analysis was done on 41 patients with TI bladder carcinoma who were followed for more than three months after initial treatment (40 TUR and 1 segmental cystetomy). We examined the predictive value for tumor recurrence of the initial grade. the number and size of tumors and the initial urine cytology. The results obtained are as follows. l. During the total follow-up of 558 months in 41 patients, there were a total of 31 recurrences with a recurrence rate per 100 patient-months of 5.6. 2. A statistically significant prognostic factors were the grade and the number of tumors (p0.05).

Management of Lower Ureteral Calculi Using Rigid Ureteroscope / 대한비뇨기과학회지

Since January 1988 a group of 54 patients presenting with stone in the lower third of the ureter have been treated with rigid ureteroscope. In 47 cases(87 per cent) the stone was removed successfully. The associated number of complication was low, with most patients being treated conservatively. Our results confirm the safety and efficiency of ureteroscopy to manage the lower ureteral stones.

A Case of Complete Duplication of the Urethra in Male / 대한비뇨기과학회지

Duplication of the urethra is an unusual congenital anomaly. It exists in two distinct forms, either complete or incomplete : complete form is a rarer anomaly. We presented a case of complete duplication of the urethra in 27-year-old male with brief review or literature.
