Complicated Renal Cyst as a Cause of Renal Colic and its Endoscopic Treatment
Main Article Content
Renal cysts have a prevalence of 10% in the general population. Although they are usually asymptomatic, around 8% will develop complications such as cystic infection. A 75-year-old female presented with flank pain and hematuria. Computed tomography showed a dominant cyst with connection with the excretory system, as well as ipsilateral hydronephrosis secondary to pyelo-ureteral obstruction. A double J catheter was installed, and antibiotic treatment was started. One month later, she was admitted for ureterorenoscopy which revealed communication between the main cyst and the urinary tract, and proceeded to perform
endoscopic drainage of the cyst.
