Summary
Hydronephrosis causing acute kidney injury is rare. Surgical repair of the pyelo-ureteral junction obstruction, including pyeloplasty, effectively restored kidney function in two reported cases.
Area of Science:
- Nephrology
- Urology
- Pediatric Surgery
Background:
- Acute renal failure (ARF) secondary to hydronephrosis is uncommon.
- Bilateral pyelo-ureteral junction (PUJ) obstruction can lead to significant renal impairment.
Observation:
- This study reports two cases of ARF caused by bilateral PUJ obstruction.
- Diagnostic methods included ultrasonography and descending pyelo-ureterography (DPU).
- One patient presented with a concurrent infection.
Findings:
- DPU revealed an absence of opacification, confirming the obstruction.
- Initial management involved percutaneous nephrostomy.
- Subsequent surgical intervention, including pyelo-ureteral resection and Anderson-Hynes pyeloplasty, was performed.
Implications:
- The surgical approach demonstrated a high success rate (95%).
- Renal function was satisfactorily recovered post-operatively.
- This highlights the efficacy of surgical correction for PUJ obstruction-induced ARF.
