# Simultaneous treatment of renal cysts and ipsilateral stones with retroperitoneoscopic surgery: report of two cases

## TL;DR

This paper reports two cases where retroperitoneoscopic surgery successfully treated both kidney cysts and stones in the same operation.

## Contribution

The novelty is demonstrating a single retroperitoneoscopic approach for treating co-occurring renal cysts and stones.

## Key findings

- Retroperitoneoscopic surgery effectively removed both renal cysts and stones in two patients.
- The combined approach was safe and yielded good treatment outcomes.
- This method is a viable option for selected patients with co-occurring renal cysts and stones.

## Abstract

A simple kidney cyst is the most common type of renal cyst. These cysts are usually asymptomatic and detected incidentally upon radiological exams of the abdomen. Currently, there are many methods of treating renal cysts, in which retroperitoneoscopy to remove the cyst is a safe and more effective method. However, the simple renal cyst with renal pelvis stones will raise a question in the approach.

In this report, we present two cases, admitted to the hospital with abdominal pain and diagnosed with a simple renal cyst with renal calculis. The two patients underwent retroperitoneal laparoscopic treatment of renal cyst and renal calculi in one surgery.

We want to discuss and share our experience in surgically treating these exceptional cases.

In two cases, we chose the retroperitoneoscopic technique to remove the renal cyst and the renal stone, which resulted in good treatment results. This is an effective and safe alternative for the simultaneous treatment of renal cysts and ipsilateral renal calculi in carefully selected patients.

Simple renal cysts and renal calculi are two common urinary system diseases with many effective treatment methods.

However, the co-occurrence of both simple renal cysts and renal pelvis stones in the same kidney may result in different intervention strategies, depending on each patient's case.

In this case, we chose the retroperitoneal endoscopic technique to resect the renal cyst tip and remove the renal pelvis stones, which has brought about good treatment results.

This is an effective and safe alternative for simultaneously treating renal cysts and calculi on the same side in carefully selected patients.
