This study reviewed 23 years of retrocaval ureter cases. Surgical intervention in symptomatic patients effectively improved renal function.
Area of Science:
- Urology
- Surgical Science
Background:
- Retrocaval ureter is a rare congenital anomaly.
- This study details a 23-year experience with diagnosis and treatment.
Purpose of the Study:
- To report findings on the diagnosis and management of retrocaval ureter.
- To analyze clinical manifestations and treatment outcomes.
Main Methods:
- Retrospective review of 13 patients diagnosed with retrocaval ureter.
- Diagnostic imaging included intravenous urography and retrograde pyelography.
- All symptomatic patients underwent surgical correction.
Main Results:
- The mean patient age was 23 years, with 92.3% being male.
- Common presentations included pyelonephritis (53.8%) and flank pain (30.8%).
- All patients had type 1 right-sided retrocaval ureter; no associated anomalies were found.
Conclusions:
- Pyelonephritis was the most frequent reason for presentation.
- Surgical treatment is indicated for symptomatic retrocaval ureter and improves renal function.
