Clinical Context
A typical patient is an adult presenting with suspected or confirmed urinary tract obstruction, nephrolithiasis, recurrent urinary infections, or hematuria requiring diagnostic or therapeutic urinary tract imaging or intervention. The clinical workflow begins with outpatient evaluation by a primary care physician or urologist, including history, physical exam, and urinalysis. Imaging (e.g., renal ultrasound or non-contrast CT) identifies hydronephrosis or stones. The patient is scheduled for an interventional urology procedure in an ambulatory surgery center or hospital outpatient department. Peri-procedure steps include informed consent, pre-procedure labs, anesthesia evaluation (local, regional, or general depending on complexity), intra-procedural fluoroscopic or endoscopic guidance, and a short post-procedure observation period before discharge. Typical sites of service are the ambulatory surgery center, hospital outpatient department, or inpatient operating room for complex cases.
