The incidence increases with age, as at least 50% of people above the age of 50 have a simple cyst in one of the kidneys [12]. Overall, ultrasound services can help in finding out chronic kidney diseases or any renal issues. For percutaneous nephrostomy and abscess drainage, either the one-step or the Seldinger technique is used.
