A case of congenital urethral diverticulum is presented. The patient was a 16-year-old boy with the chief complaint of dribbling urine since he was 14 years old. A retrograde urethrogram revealed a diverticulum of the bulbar urethra, which had been produced by a cystic dilation of the Cowper's gland duct. The walls of the diverticulum were resected endoscopically.
Two patients with nonfunctioning kidney were treated with retroperitoneal laparoscopic nephrectomy. The working space in the retroperitoneum was created by balloon dissector consisted of surgical glove and rigid nephroscope.

In these two cases, the kidney were removed successfully without any complication. The operating time was 165 min and 219 min, respectively.
