Q. A 38-year-old man presents to the clinic complaining of recurrent flank pain and urinary tract infections. He has a past medical history significant for hypertension and a family history significant for polycystic kidney disease. On examination, he has bilateral palpable flank masses, and his blood pressure is 140/90 mm Hg. Laboratory investigations show mildly elevated creatinine at 1.5 mg/dL and urinalysis is positive for proteinuria. Imaging studies confirm bilateral renal cysts consistent with polycystic kidney disease. What is the most appropriate management of this patient's polycystic kidney disease?
