[Complete ureteric duplication associated with ureterocele: two cases report].

Area of Science:

• Pediatric Urology
• Congenital Anomalies
• Urinary Tract Imaging

Background:

• Complete ureteric duplication is a congenital anomaly where a single kidney has two ureters.
• Ureteroceles are cystic dilations of the ureter within the bladder, often associated with duplication anomalies.
• These conditions can lead to complications such as urinary tract infections and hydronephrosis.

Observation:

• Two pediatric cases of complete ureteric duplication with ureterocele are detailed.
• Case 1: A 4-month-old girl with fever and cloudy urine presented with a duplicated collecting system and upper pole ureterocele.
• Case 2: A 16-month-old girl with recurrent urinary tract infections showed a hydronephrotic lower pole, a "drooping flower" appearance, and an upper pole ureterocele.

Findings:

• Ureterocystoneostomy was performed for the upper pole ureterocele in Case 1, resulting in mild upper pole hydronephrosis postoperatively.
• Left heminephrectomy with partial ureterectomy was performed for the severely affected upper pole in Case 2, leading to an uneventful recovery.
• Imaging findings included antegrade pyelograms demonstrating duplicated systems and ureteroceles, and excretory urograms showing hydronephrosis and atrophy.

Implications:

• Management of complete ureteric duplication with ureterocele requires tailored surgical approaches based on individual presentation.
• Early diagnosis and intervention are crucial to prevent long-term renal damage and complications.
• These cases highlight the spectrum of clinical presentations and surgical outcomes in managing this complex congenital anomaly.
