Ureterocele in adults. A follow-up study of 28 adult patients treated with transurethral diathermy incision.

During an 18-year period, 28 adults with ureterocele were admitted to hospital with uncertain urological or abdominal symptoms. All of the ureteroceles were treated with transurethral diathermy incision. At follow-up examination after a mean observation time of 7 years, 16 of 20 patients were free from symptoms and the other 4 had only minor loin pain or dysuria. Significant vesico-ureteric reflux or depression of the renal filtration rate did not develop in any case. It is concluded that simple transurethral incision is adequate for treatment of small or medium-sized ureteroceles in adults.
