Abstract: Background and Goals: The most common type of renal cystic lesions are simple renal cysts. They are often spherical or oval, one or more, unilateral or bilateral, and contain a clear or straw-colored fluid that resembles plasma. To evaluate the success rate for catheter against needle aspiration in renal cysts and investigate the efficacy of per cutaneous aspiration of uncomplicated renal cysts. Methods: Fifty individuals with mildly symptomatic renal cysts are included in this prospective trial. From February 2024 until June 2025, US-Guided Aspiration was performed as an outpatient operation at the radiology department of Al Sadder Medical City. Using the US criteria for a simple renal cyst, individuals were chosen based only on their symptomatic status. Every patient who was recommended by the urology department completed comprehensive consent papers that included all information regarding the treatment and any potential risks. The patient was created using a unique algorithm, and the data was statistically examined using SPSS version 20, where the chi-square test was used for categorical data and the independent sample T-test on measurement data. P values less than 0.05 are considered significant. Findings: This study included fifty participants with kidney cysts. There were 31 (62%) female patients and 19 (38%) male patients. The average age of the patients was 52.7 (35-77) years. There were 26 (52%) on the left and 24 (48%) on the right. The average diameter of the cysts was 7.68 (4.5–10.5) cm. Cysts aspirated through a needle had a mean diameter of 6.81 cm, whereas cysts drained via catheter had a mean diameter of 8.54 cm. Only 12 out of 50 patients (24%) show symptomatic failure, which indicates that their pain has returned over time, whereas 38 out of 50 patients (76%) typically show symptomatic success, which indicates that their pain was successfully reduced. Conclusions: Simple Percutaneous aspiration of a minor renal cyst can be a minimally invasive, well-tolerated procedure that can be utilized as a first line of treatment for simple renal cysts that are symptomatic and has a relatively high symptomatic success rate. Additionally, neither preparation nor hospitalization are required. A small 5F catheter can be used to drape a small renal cyst, and it works better than aspirating it using a needle. It can also be used for larger renal cysts.
