# A case of post‐renal acute kidney injury caused by bilateral ureterolithiasis

## TL;DR

A rare case of kidney injury caused by blocked ureters due to stones was successfully treated with stents.

## Contribution

Highlights the importance of considering post-renal AKI due to bilateral ureterolithiasis in clinical practice.

## Key findings

- Bilateral ureterolithiasis can cause post-renal acute kidney injury.
- Treatment with bilateral retrograde ureteric stenting was successful in this case.

## Abstract

Bilateral ureterolithiasis is rare but can cause acute kidney injury (AKI). Clinicians should first examine for post‐renal causes of AKI, even if the patient lacks subjective symptoms.

This letter describes a case of bilateral ureterolithiasis which presented with post‐renal acute kidney injury (AKI) and was successfully treated by bilateral retrograde ureteric stenting. Clinicians should be aware of post‐renal AKI caused by bilateral ureterolithiasis when acute worsening of renal function with oliguria is observed.
