1/5. Acute retention of urine due to prolapsed ectopic ureterocele in an adult male.

    A case is presented of prolapsed ectopic ureterocele which produced severe urinary retention in a 31-year-old male patient. The usefulness of lumbar transcutaneous puncture is emphasized in a case associated with a non-functioning upper pole of a duplex kidney.

2/5. Ultrasonic evaluation of the obstructed duplex kidney.

    The problem of a duplex collecting system associated with an obstructed ectopic ureter or ureterocele is common in pediatric urology. Four such patients were studied by gray scale ultrasound which was useful in demonstrating the dilated upper pole collecting system as well as an ectopic ureter and a ureterocele. Although the diagnosis of a nonfunctioning upper pole unit in a duplex kidney is usually suggested by the urogram, ultrasound provides a noninvasive means of confirmation which is independant of function. Further, ultrasound-guided puncture with antegrade pyelography demonstrates the course of the ectopic ureter, thus providing a more complete preoperative evaluation.

3/5. Transurethral puncture in management of ectopic ureteroceles.

    In the past, treatment of ectopic ureteroceles with duplicated collecting systems with little or no function in the upper pole segment has been heminephrectomy, often followed by reconstruction of the ureterovesical junction. Herein we review our initial use of transurethral puncture of ureteroceles to initiate drainage with potential return or improvement of function to the upper pole segment. The initial goal was to do pyelopyelostomy rather than heminephrectomy with less potential morbidity to the patient and preservation of functional renal tissue.

4/5. diagnosis and treatment of fluid-filled renal structures in children with ultrasonography and percutaneous puncture.

    The application of ultrasonographic and percutaneous needle puncture techniques in the diagnosis of various fluid-filled renal anomalies has permitted rapid delineation of anatomic detail, more definitive physiologic evaluation, and drainage, when necessary, in a safe and cost-effective manner. Its usefulness in children is emphasized in 6 illustrated cases of male infants with minimally or nonopacified renal anomalies, one of the more difficult diagnostic problems in pediatric urology.

5/5. Prenatal bladder outlet obstruction secondary to ureterocele.

    We present 2 cases of prenatal hydroureteronephrosis and bladder outlet obstruction due to an obstructing ureterocele. Both neonates were stabilized and managed with early endoscopic decompression. Neither infant demonstrated significant function in the kidney ipsilateral to the ureterocele either before or after ureterocele puncture. There have been few cases reported of prenatal bladder outlet obstruction due to a ureterocele. Our limited experience has been poor with regard to salvaging the affected upper tract. Future definitive management will be tailored as more of these cases are documented.
