Summary
Simple renal cysts are common, especially in older adults, and their size and location impact the kidneys. However, cyst characteristics did not correlate with patient symptoms or pelvicalyceal system effects.
Area of Science:
- Radiology
- Urology
- Nephrology
Background:
- Simple renal cysts are frequently observed findings in abdominal imaging.
- Understanding their incidence and impact is crucial for clinical management.
Purpose of the Study:
- To determine the incidence of simple renal cysts.
- To analyze the relationship between cyst size, location, and their effect on the pelvicalyceal system.
- To correlate cyst characteristics with patient symptomatology.
Main Methods:
- Abdominal ultrasound examinations were performed on 2010 patients.
- 198 simple renal cysts were identified in 110 patients and categorized by size.
- The relationship between cyst size, location, symptoms, and pelvicalyceal system effects was evaluated.
Main Results:
- The male to female ratio was 1.4:1.
- Simple renal cysts were most common in patients over 50 years old.
- A notable 2% incidence of renal cysts was observed in children.
- Thick walls, calcification, and multilocularity were rare (1% each).
- Associated liver cysts occurred in 2% of cases.
Conclusions:
- A significant relationship exists between simple renal cyst size/location and their effect on the calyces.
- No clear correlation was found between patient symptoms and the effect on the pelvicalyceal system.
